本文通过对鄂西武陵山区农村的田野调查发现,熟人社会网络主要依靠传统儒家伦理来维持,呈现出关系化的社会网络状态,这种社会网络呈现单一和发展规模有限等特点。随着人口城乡流动剧增,特别是大批农民工进城以及返乡以后,原本相对单一的重构方式趋于多元化,并呈现着关系化和类别化等多重社会网络并置的状况。多重社会网络并置现象既是城乡流动的体现,也是不同人群基于生存选择而将乡土性和城市性编入日常生活实践的结果。其生成对于重新理解国家、社会和个人的关系,以及进一步理解中国社会转型过程中的差序格局及公私边界等问题有着重要启示意义。

This study focuses on assessing the dynamic behaviors of carbon SupercompositeTM laminates when subjected to high strain-rates and air blast loads, using a shock tube for testing. The investigation aims to understand the response of these advanced materials under extreme conditions, which is crucial for applications in aerospace, military, and other high-performance industries. SupercompositeTM (CZE) prepreg, made up of a 3K plain weave carbon fabric with milled carbon fibers as interlaminar reinforcements impregnated with epoxy, is used to create SupercompositeTM (CZE) laminates. A woven carbon composite (CBE) laminate was also created using 3K plain weave Carbon/Epoxy (CBE) prepreg. Both types of laminates were designed and fabricated using the autoclave process. The dynamic behaviors of CZE and CBE laminate under transverse compression loads were evaluated using a modified Split Hopkinson Pressure Bar (SHPB). The study found that the 3D reinforcement with milled carbon fibers significantly affected the dynamic behavior of the CZE laminate. Stereo imaging videos, captured using two SHIMADZU high-speed video cameras in shock tube experiments, recorded the time history of back surface deflection. The plate specimens exhibited low deflections without any visible damage. The experimentally observed center point deflections of the CZE plates decayed sooner than those of the CBE laminates, indicating an improvement in damping due to the presence of 3D reinforced milled carbon fibers. This research shows that optimized utilization of milled carbon fibers as 3D reinforcement can withstand high stress in the thickness direction and higher energy absorption when subjected to impact and high strain-rate loading.

Aim: To study the effect of vaseetomy on histological appearance of the testis. Methods: Parkes strain mice wereused as the animal model; they were bilaterally vasectomized (Vx) or sham-operated (So) and killed at intervals of 4,6, 9, and 12 months after the operation. Testes were excised from 5 Vx and 5 So mice at each interval and processed for histological examination. results: Testes of So mice showed normal histological features. By contrast, marked al-terations were observed in the seminiferou tubules in testes of Vx mice, except in those killed 4 months after the opera-tion. The seminiferous epithelium in the tubules was only 2-3 layers thick and showed much depletion of germ cells;in severe cases, the epithelium consisted of only a thin layer of Sertoli cells, spermatogonia and a few *** of germ cells, occurrence of multinucleated giant cells and vacuolated appearance of the epithelium were ofcommon features in the tubules. Furthermore, lumen of the rete testis in Vx mice was greatly dilated and showed accu-mulation of sermatozoa with immature germ cells; in mice vasectomized for 6-12 months, several macrophages in-gesting spermatozoa were ofte observed in the lumen of the rete testis. Spermatic granuloma was also somettimes no-ticed in corpus or in cauda regions of the epididymis in mice vasectomized for 6-12 months. Conclusion: We sug-gest that consequences of vasectomy should be thoroughly understood in order to make this method rather more popularas a reversible method of male contraception.
