Experimental mice were exposed to Trypanosome evansi after injection by different doses of antigenic reservoir. The results showed that 20 μg dose produced 83% and 67% protection to 2 sample variations after 4 immunizations. However, 3 immunizing doses could not give good protection. No protective effects were detected when experimental animals immunized by single VSG exposed to isotype from different rabbits.

Three components of peroxide in the activator amongwhich have the different decomposed temperatures made the Vinyl-ester resinsolidified heat discharge increased that gained a bigger solidified degree. Theactivator-adopted quantity can dramatically affect the casting samples performance:eg. When use 1.0-1.4 portions of activator, the casing sample can reach its maximumTensile strength and Bend strength; when use more activator, the polymeric meshworkcontracted which embrittle the casing sample and reduce the dynamic performance; Inthe Pultrusion processing, when CF composed of about 60vo1%, more demould agentcan bring the better processing but degrade the CFRP, normally use around 1.2 portion.

采用具有不同分解温度的三组分有机过氧化物引发剂，乙烯基酯树脂的固化反应放热量增加，固化程度提高；引发剂用量对浇注体的性能影响很大，在用量为 1.0~1.4 份时，浇注体拉伸强度剂弯曲强度达到最高，过多的引发剂使聚合网络减小，浇注体变脆，力学性能降低；在拉挤成型工艺中，碳纤维的体积含量一般为 60%左右，脱模剂增加使加工性能好转但会使复合材料性能下降，一般用量为 1.2 份。

How to process it affects the equivalent prediction of the entire conductor performance. According to the traditional composite theory, the following several predictions were carried: only consider the functions of the stainless steel conduit outside the cable body, the double insulation and the double shielding layer; the influence of the flexible cable body is neglect, so only consider the function of its internal helium tube; the material nature of the cable body is assumed the isotropism, which the elasticity modulus is 1-10 GPa (here taking 2 GPa); combining the homogenization theory with the composite damage theory.
