查询词典 sheath

Friction wheel、wedge-shaped sheath fixed on central pipe,other parts fixed on swivel lower shell by bolts.

For most piercing-sucking insects, they will secrete gell saliva and watery saliva when they feed on plants. The gell saliva will be secreted at the early stage of feeding to form salivary sheath, which is supposed to surround and protect the stylet. This saliva can help piercing-sucking insects to feed on plants directly and indirectly. Meanwhile, the watery saliva contains many components like pectnase, cellulose, polyphenol oxidase, peroxidase, alkaline phosphatase, sucrase, etc. These components can help piercing-sucking insects in plant tissue penetration, food digestion, detoxification of plant secondary substances and break-down of plant defence reaction.

对多数刺吸式昆虫而言，他们取食时会分泌胶状和水状两种唾液，其中胶状唾液会在取食早期分泌形成唾液鞘来围绕并保护口针，通过直接和间接的作用来帮助取食；而水状唾液中则包含了果胶酶、纤维素酶、多酚氧化酶、过氧化物酶、碱性磷酸酯酶、蔗糖酶等组分，来帮助刺吸式昆虫对植物穿刺、消化食物、解毒次生物质并破坏植物的防御反应。

Results In both groups after injury, several changes on oculomotor nerve occurred including number reduction of neurons, dispersion in distribution, disappearance of sub-nuclear structure, structure destruction of fibers and myelin sheath, neurite gemmation, and specificity decrease in fibers distribution, while all these changes in section-suture group were more obvious.

结果 不同损伤均可导致神经元的数量减少，分布散乱，亚核分布结构改变，神经纤维和髓鞘的结构破坏，轴突芽生及再生纤维分布的特异性降低，而且上述改变在神经切断组更加明显。

It is clearly possible, moreover, for a particular style to come in and go out of fashion repeatedly. Some example of such "ins and outs" of fashion are peasant blouses, sheath dresses, padded shoulders, and circular skirts, to name but a few.

除此之外，也有可能存在某种特殊的风格款式重复的作为时尚出现的情况，这些特殊的风格款式有村姑衫，女士紧身裙，衬肩，和西裙，但是只有少数。

He pulled Goliath's sword from its sheath and cut off the giant's head.

他从剑鞘里拔出歌利亚的剑，把这个巨人的头切了下来。

In the darkness he loosened his sheath knife and taking all the strain of the fish on his left shoulder he leaned back and cut the line against the wood of the gunwale.

他摸黑拔出鞘中的刀子，用左肩承担着大鱼所有的拉力，身子朝后靠，就着木头的船舷，把那根钓索割断了。

Objective: To investigate use of poloxamex of selfmade sheath reagent for fully automatic hemocyte analyzer.

目的：研究泊洛沙姆在SE9000全自动血液分析仪用自制鞘液中的应用。

The results show that the compound conductive fiber has typical structure of sheath-core consists of black greened polyaniline electric conductive deposition as the skin and the white polypropylene matrix fiber as the core, which makes the compound fiber preferable physical mechanical property. The intensity and the elongation ratio of the electric conductive fiber are decreased but the thermal stability is enhanced after modified. The compound fiber has the good acid resistance but poor base resistance. The thermal stability of the compound fiber prepared by 4-methyl-benzene sulfonic acid is better than that prepared by hydrochloride acid. Moreover, the compound fiber can be re-doped by other organic or inorganic acid after freed from the adsorbed acid. Furthermore, the electric conductivity of the compound fiber decreases with the temperature increasing but hardly changed with the humidity. The adsorptive ability and therefore the content of the polyaniline, the constant of electric conduction, and the durability of the compound fiber can be enhanced by thinning the diameter, section heteromorphosis, section heteromorphosis and plasma treatment of the surface or blending with COPET of the fiber.

结果表明：复合纤维是聚丙烯与聚苯胺的共混体系，具有典型的皮芯型结构，皮层为墨绿色的聚苯胺沉积层，形成连续的导电通道，芯层为白色的聚丙烯基质纤维，提供物理机械性能；导电改性后纤维的强度、强力和伸长率均有下降，但热稳定性得到提高；复合纤维的耐酸性比耐碱性好，以对甲苯磺酸做掺杂酸比盐酸掺杂聚苯胺热稳定性好，脱掺杂后的复合纤维，可用其它无机酸或有机酸进行再掺杂；复合导电纤维的电导率随温度升高降低幅度较大，但几乎不受湿度影响；基质纤维细旦化、截面异形化、表面等离子体处理或共混COPET等改性处理均能提高纤维的吸附性，进而提高复合纤维表面聚苯胺含量、电导率和耐久性。
