| 2 | Some Investigations on Early Organization of Karst System显示文摘Some investigations on the early organization of karst system are carried out through modeling the dissolution evolution processes of stochastic fracture networks in carbonate rock. It is assumed that water flow in fracture network is laminar, and the dissolution rate process can be described with an empirical equation, The results suggest that a karst system is a self-organization system. It can spontaneously create higher hierarchical level out of a relative homogeneous structure through amplifying the microscopic heterogeneity of initial flow field. Under given boundary conditions, a karst system with initial fracture network of varied hierarchical levels is likely to have stronger tendency to lead to a typical karst system featuring conduit passages than a system with initial network of unique hierarchical level. Through merging local flow systems, a karst system concentrates the limited flow into a few pathways to promote the formation of higher hierarchical level. | Yu Qingchun(Geofront Laboratory, Department of Civil Engineering, Kyoto University, Kyoto 606-8501, Japan)Shen Jifang Wan Junwei(Department of Hydrogeology and Environmental Engineering, China University of Geosciences,Wuhan 430074, China)Ohnishi Yuzo(Geo | 1999 | Journal of Earth Science1999，18，4： | 8 |

| 4 | LOCAL SCOUR ESTIMATION AT BRIDGE SITE: MODIFICATION AND APPLICATION OF LACEY FORMULA显示文摘In the recent years, it has been established that b/h or h/b (b = length of the structure in the lateral direction and h = approach flow depth) is the dominant factor for the estimation of local scour depth around abutments and piers. One of the major limitations of the Lacey formula is that it predicts only one value of the scour depth for a specific river because of the absence of important parameters b and h. Therefore, its application is quite uncertain for variable b and h. Considering its limitations and experimental facts of flow concentration and shear stress amplification close to above structures, the original Lacey formula is modified introducing the parameters b and h. The applicability of the original as well as modified Lacey formula is tested to the data collected from major rivers in Bangladesh. | Md.

| 5 | Genesis of continental seismogenic zone and a new fault zone model显示文摘Experiments were conducted repeatedly on Mannari granite under different temperature and confining pressure conditions. Systematic micro- and submicro-structural and mechanical analyses of granite samples deformed under 1.5 GPa (confining pressure), at 25 ℃-650 ℃ temperatures and at 2×10-6s-1 strain rate show the brittle-ductile deformation microstructures and microstructural associations similar to those observed in naturally deformed crustal rocks and minerals. Brittle fracturing and crystalline plasticity co-exist and react with each other in the brittle-ductile transition domain of the continental lithosphere. The interaction between the different mechanisms in the transitional domain results in the variation of anomalous strength values, which may best explain the genesis of the continental seismogenic zone. A new fault zone model is proposed on the basis of detailed micromechanical and microstructural analyses. | LIU Junlai & M. Shimada1.

| 6 | Transformation Plasticity─The Effect on Metallo-Thermo-Mechanical Simulation of Carburized Quenching Process显示文摘Theory of metallo-thermo-mechamics and the developed CAE code offer a powerful tool to simulate residual stresses and distortion during heat treatment processes, in which the transformation plasticity is one of factors to be considered being coupled with stress/strain and metallic structure. It is pointed out in this paper that, especially in the case of carburized quenching, transformation plasticity plays very important role on the distortion, which is verified by axisymmetric finite element, employing heat treatment simulation code 'HEARTS'. Simulated results with the careful consideration on the effect of transformation plasticity reveal to improve remarkably the accuracy of prediction of the displacement and the mode of distortion, compensating the discrepancy between experimental and calculated results. Attention is also paid on the difference in transformation plasticity and conventional plasticity in simulating the volume fraction, stress and strain in ring-shaped specimen during quenching. Moreover some discussions are made on practical use of the effect, and recent experimental results on the coefficient of transformation plasticity are presented. | Shigeru Yamanaka, Takayuki Sakanoue, Toshikazu Yoshii, Tatsuo Inoue 1.

| 7 | Zero initial partial derivatives of satellite orbits with respect to force parameters violate the physics of motion of celestial bodies显示文摘Satellite orbits have been routinely used to produce models of the Earth's gravity field. In connection with such productions, the partial derivatives of a satellite orbit with respect to the force parameters to be determined, namely, the unknown harmonic coefficients of the gravitational model, have been first computed by setting the initial values of partial derivatives to zero. In this note, we first design some simple mathematical examples to show that setting the initial values of partial derivatives to zero is generally erroneous mathematically. We then prove that it is prohibited physically. In other words, set-ting the initial values of partial derivatives to zero violates the physics of motion of celestial bodies. | XU PeiLiang Disaster Prevention Research Institute, Kyoto University, Uji, Kyoto 611-0011, Japan | 2009 | Science China Earth Sciences2009，52，4： | 2 |

| 11 | Shear Strength Behavior of Two Landfill Clay Liners显示文摘Direct shear tests were conducted to obtain both the shear strength of compacted clay liners (CCLs) specimens and the interface shear strength between compacted clay liner and base soil. These experiments were conducted under the conditions of five different water contents. The experimental results show that shear strength of both CCLs and CCLs/base interface decreases with the increase in the water content of CCLs and base soil. In addition, the considerate concentration of NaCl in leachate has no deteriorating effect on the shear strength of liners. Triaxial shear tests were also conducted on clay liner specimens to obtain total and effective shear strength under a fast compression. The shear strength parameters with total stress are =18.5° and c =30 kPa for clay bentonite, and =48.5° and c =90 kPa for sand bentonite and those with effective stress are ’=27.2° and c’ =25 kPa for clay bentonite, and ’=35° and c ’=100 kPa for sand bentonite, respectively. These results indicate that the compacted clay bentonite shows normal consolidation, but that the compacted sand bentonite exhibits over consolidation. | Jian Wenxing Engineering Faculty, China University of Geosciences, Wuhan 430074 Masashi Kamon Toru Inui Department of Global Environmental Engineering, Graduate School of Engineering, Kyoto University,Kyoto, 606 8501, Japan Takeshi Katsumi Department of Civil Engineering, Ritsumeikan University, Kusatsu, Shiga, 525 8577, Japan | 2002 | Journal of China University of Geosciences2002，13，3： | 1 |
| 12 | Urban-Rural Comparison of Nutrient Intake by Adult Women in Shaanxi Province, China显示文摘Triplet surveys were conducted in the city of Xi’an and two villages (one in the vicinity and the other at a distance) in Shaanxi fuvince in China in October-November (when agricultural activitis were low), 1997, to elucidate nutrient intakes with a focus on possible urban-rural differences. Total food duplicate samples were collected from non-smoking and non-habitually dhnking adult healthy women (ahout 50 subjects per site and 149 in total). The nutrient intakes were estimated from the weight of food items in reference to national food composition tables. On average, the women took 1873 kcal energy, 54 g protein and 37 g lipid per day, with a lipid eneny ratio of 18.4%. Both excess and insufficient energy intake was observed as a result of food intake analysis and body mass index determination. With regard to minor nutrient intakes, insufficiency was serious in the case of calcium, vitamin A and vitamin B2, but not with iron. Whereas dependency on plant foods for sources of energy and protein was common to the three regions, Xi’ an people consumed more animal foods than those in the villages. Intake of fish and shellfish was quite low throughout the three regions. Among the four types of cereals, wheat was consumed most substantially in the three regions and in three meals (except for the village where people essentially did not take lunch in reflection of low agricultural activities), whereas rice was consumed more in Xi’an than in the two villages. Maize consumption was higher in the two villages (especially for breakfast) than in the city.In contrast, foxtail millet (although in small amounts) was taken primarily in Xi’an and ouly at the time of breakfast. | HARUO NAKATSUKA ZHANG ZUO-WEN QU JIANG-BIN GAO WEI-PIN DENG YI-JUAN SHINICHIRO SHIMBO TAKAO WATANABE NAOKO INOGUCHI-MATSUDA KAE HIGASHIKAWA AND MasAYUKI IKEDA(Miyagi University, Taiwa-cho 981-3298, Japan)(Department of Food and Nutrition, Kyoto Wome | 1999 | Biomedical and Environmental Sciences1999，12，4： | 0 |

| 16 | Preliminary study of the tight lattice pressured heavy water reactor loaded with Pu/U and Th/U mixed fuels显示文摘To improve nuclear fuel utilization efficiency and prolong fuel cycle burn-up, a tight pitch lattice pressured heavy water reactor was investigated as an alternative of next generation of power reactors. It is shown that the high conversion ratio and negative coolant void reactivity coefficient are challenges in the reactor core physics designs. Various techniques were proposed to solve these problems. In this work, a tight pitch lattice and mixed fuel assemblies pressured heavy water reactor concept was investigated. By utilizing numerical simulation technique, it is demonstrated that reactor core mixed with Pu/U and Th/U assemblies can achieve high conversion ratio (0.98), long burn-up (60 GWD/t) and negative void reactivity coefficients. | XU Xiao-Qin, XU Qiu, YOSHIIE Toshimasa, SHIROYA Seiji (Nuclear Science Department, Research Reactor Institute, Kyoto University, Osaka 590-0494, Japan) Engineering | 2001 | Nuclear Science and Techniques2001，12，4： | 0 |

| 18 | Microstructure and Mechanical Properties of Two-phaseTiAl Alloys in Lamellar Form显示文摘In two-phase TiAl alloys, the lamellar structures are of special interest and importance since they are so common and persistent. not only under as-cast conditions but also after thermal treatment. However. the lamellar structures are still poor in ductility,although they are beneficial for toughness and high temperature strength. This article will review the recent progress made in understanding the basic mechanical properties of the γ and α2 phases which comprise the two-phase alloys in Iamellar form, and discuss how an improved balance of strength and ductillty in the lamellar form may be | Masaharu Yamaguchi and Haruyuki Inui(Department of Metal Science and Technology, Kyoto University, Sakyo-ku, Kyoto 606, Japan) | 1994 | Journal of Materials Science & Technology1994，10，3： | 0 |
| 19 | Copper Elimination from the Molten Steel by Addition of Hydronitrogens显示文摘A novel method has been proposed to remove copper from molten steel by adding the compounds of hydrogen and nitrogen into the melt at normal pressure. Feasibility experiments were carried out in Mo-wire resistance furnace at 1600℃. The copper content of about 400 g 45 steel were reduced from 0.60% and 0.57% to 0.41% and 0.51% with 3.25g and 1.20 g NH4Cl respectively, while the copper contents of about 300 g steel melt were reduced from 1.15% and 0.61% to 0.90% and 0.56% with 4.10 g and 2.00 g NH2CONH2. These results indicate that the proposed method is very promising to be put into practical and worthwhile of further study. | Liansheng Li~(1)) Changxiang Xiang~(1)) Jie Cao~(1)) Shiqi Ii~(1)) Eiji Ichise~(2)) 1)Applied Science School, UST Beijing, Beijing 100083, China 2) The Kyoto University, Kyoto, Japan | 1998 | International Journal of Minerals,Metallurgy and Materials1998，12，2： | 0 |
