Antibacterial function of body wall was conducted by the following way: microorganism was directly resisted through the change of cuticle, such as incrassation of up-cuticle protuberance and increasing length of micro-floccus in the up-cuticle dissociation surface; exudation function of large granular orthochromatic mucous cells and reticulation mucous cells in the epidermis could be enhanced when the Eisenia fetida was induced by E. coli. Moreover, the mucus that contained compound substance of mucopolysaccharide and protein could make the bactericidal function or dilute the microorganism on the surface of earthworm, which could protect earthworm from invasion of microorganism; the content of neutral mucopolysaccharide of antibacterial function could be increased according with the exudation increment of small granular proteinaceous cells in the epidermis, which could resist bacteria invading into the epidermis of earthworm.

The value of the hardness of mung bean decreased as the soaking time increased. On the other hand, the hydration rate constant of mung bean increased, but the equilibrium of the moisture content decreased. Higher temperature could be conducive to reaching an equilibrium of the moisture content and shorten soaking time. On the microstructure, observation soaking could promote mung bean seed coat to absorb water, that might make its spongy mesophyll swell and inner wrinkly structure more smooth . During soaking at 50℃ and 70℃ for two hours, the surface and palisade parenchyma of the mung bean seed coat cracked, and pectic substances of the middle lamella were loss. Because of this, soaking rate could raise and shorten the soaking time.
在硬度测试中,则呈下降趋势;在绿豆吸水特性方面,其吸水速率常数呈增加趋势,而水分平衡常数则呈下降趋势;浸渍温度之提升有助於达到浸渍平衡及缩短浸渍时间;配合绿豆微细构造之观察,种皮会因浸渍、吸水,种皮外表的多角形海绵组织会有膨大情形,内部皱摺状构造则渐趋平滑;在50℃、70℃浸渍二小时,绿豆种皮之表皮、栅状组织会有破裂,海绵组织及中胶层果胶会有流失情形,因而使绿豆之浸渍速度提升与缩短浸渍时间。

Results show that when improving spot pitch in weld bonded joints with high elastic modulus adhesives, stresses in weld spot zone are decreased while stresses and strains at edges of overlap region are increased slightly. For the joints with low elastic modulus adhesives, both stress concentration degree at the weld spot and the shear strain at edges of overlap region are increased with the spot pitch increasing.

In this paper, test research have been performed on the two important mechanical properties indicator compressive modulus of elasticity and shear modulus. Numerical simulation has been performed on the base of results of test under the situation uniform and uneven thickness of elastomer layer, which analyze internal stress distribution of the elastomeric bearing, as follows:(1) The traditional test methods of compressive modulus of elasticity test are rather cumbersome and take up experimentalists lots of time.
