| 1 | Research on the Influence of Cutting Condition on the Surface Microstruct ure of Ultra-thin Wall Parts in Ultrasonic Vibration Cutting显示文摘In many fields of high-tech industry the ultra-t hi n wall parts are employed. In this paper the experiments were carried out to dis cuss the surface microstructure of the camera’s guided drawtube by applying ult rasonic vibration cutting device to the traditional lathe. The influence rule of the cutting condition on the surface roughness was put forward, which was drawn by comparing the ultrasonic cutting with the common cutting by use of the cemen ted carbide tool and the polycrystalline diamond (PCD) tool. The test results sh owed that the ultrasonic cutting performs better than the common cutting in the same condition. According to the test results analyzing, the surface characteriz ation is influenced clearly by the rigidity of the acoustic system and the machi ne tool, as well the setting height of the tool tip. Otherwise, the dense regula r low frequency vibration ripples will be scraped on the machined surface. When the tool tip is set higher than the rotating center of the work piece by three t imes of the amplitude of ultrasonic vibration, the vibration ripples behave alig ht; they turn light and shade alternatively when the tool tip is lower than the rotating center of the work piece by three times of the amplitude of ultrasonic vibration. According to the test result analyzing, the following conclusions are put forward: 1) The surface roughness in ultrasonic cutting is better than that in common cutting. Under a one third critical cutting velocity, the value of th e surface roughness in ultrasonic cutting rise slightly along with the cutting v elocity, while in common cutting it decreases contrast to the cutting velocity; the curves of the surface roughness in ultrasonic cutting and common cutting see m to be alike, both increase along with the feed rate and the cutting depth, but the value in ultrasonic cutting is smaller in the same condition.2) The influen ce of the coolant on the surface roughness cannot be ignored. The kerosene can b e employed to improve the surface roughness in ultrasonic machining.3) In ultras onic cutting process of aluminum alloy ultra-thin wall work piece, the PCD tool performs better than the cemented carbide tools.4) The vibration ripples result from the not enough rigidity of the acoustic system and the improper setting he ight of the tool tip. The departure of the tool tip from the rotating center of the work piece to some extent causes the vibration ripples on the machined surfa ce. | GAO Guo-fu, ZHAO Bo, JIAO Feng, LIU Chuan-shao (Department of Mechanical Engineering, Jiaozuo Institute of Technolog y, Henan 454000, China) | 2002 | 厦门大学学报(自然科学版)2002，41，S1： | 9 |

| 3 | 肝细胞来源外泌体可能成为慢加急性肝衰竭患者肝再生和预后评估的生物标志物显示文摘【据Hepatology International 2021年8月报道】题:肝细胞来源外泌体可能成为慢加急性肝衰竭患者肝再生和预后评估的生物标志物(作者Jiao Y等)慢加急性肝衰竭(ACLF)患者虽然肝损伤严重,但是部分患者仍可以通过肝脏再生得以存活,因此ACLF患者的肝再生评估尤为重要。外泌体兼具肝脏活组织检查的特异性和外周血检测的非侵袭性的优点,可能是肝脏疾病潜在的生物标志物。本研究旨在建立ACLF肝再生的外泌体表达谱模型,探讨其在肝衰竭患者肝再生及预后评估中的作用。 | JIAO Y LU W XU P 焦彦 卢旺 陈煜 时红波 马迎民 | 2021 | 临床肝胆病杂志2021，37，10： | 8 |

| 5 | 笋芽顶端分生组织在竹秆横切面形态形成中的作用与机制研究显示文摘竹秆的横切面主要由表皮、皮层、维管组织、基本组织及髓腔(早期为髓组织)组成。这些组织均由笋芽茎顶端分生组织分化发育而来,且其在生长发育过程中促使了竹秆横切面形态(本文特指:竹秆横切面外轮廓形状、围度及壁-腔结构)的形成。然而,人们对于这一生长发育过程的生物学机制知之甚少。本研究利用解剖学、数学模拟等方法,对 20 种具不同秆径竹种的笋芽顶端分生组织进行了分析。研究结果发现,笋芽顶端分生组织指状形态的维持是竹子产生圆柱形竹秆的基础;在顶端分生组织细胞数目增加的同时,线性增加原体细胞数目应是竹子在演化过程中产生大径竹秆且保持规则壁-腔结构的方式。进一步通过研究一个竹壁增厚且壁-腔架构紊乱的稳定变异体———实肚竹( Phyllostachys nidularia f. farcta)发现,其笋芽顶端分生组织细胞数目减少且原体/原套细胞数比值降低使其产生了高比例的壁组分组织(指基本分生组织与肋状分生组织)与低比例的髓组织。上述 2 种组织的比例失衡,使得实肚竹笋芽在后续发育中壁组分组织随机挤入到了髓组织中,最终形成了实肚竹异常的竹秆横切面形态(竹壁多样化增厚且壁-腔结构紊乱)。此外,相对较小的顶端分生组织,使得实肚竹笋芽产生了较少的内源激素,如其生长素含量仅约为其原种篌竹的 67. 5%,各细胞分裂素含量也显著低于篌竹笋芽。转录组分析进一步发现,在实肚竹笋芽中与激素及代谢相关的功能基因呈显著下调表达。这些生理与分子变化最终导致了实肚竹竹秆矮化、秆径减小且生物量降低。本论文的研究结果为研究竹秆横切面发育提供了一个重要的视角,同时也为实肚竹厚壁茎秆的形成提出了一个合理的机制。 | Wang Y Sun X Ding Y Fei Z Jiao C Fan M Yao B Xin P Chu J Wei Q 王雨珺 魏强 | 2019 | 世界竹藤通讯2019，17，3： | 5 |
