Filling flexibilizer , such as epoxy terminal block , polyurethane ether structure , thiokol and liquid ctbn to the system of expoxy - mannich amide , through the test on shear strength , bounding elasticity modulus and break strength of cured products , the different fuction could be found using different flexibilizers 摘要在环氧酚醛胺体系中使用端环氧基聚氨酯醚、聚硫橡胶、液体丁腈橡胶等活性增韧剂，通过对固化物剪切强度、弯曲弹性模量及断裂强度的测试对比，可以看出不同增韧剂效果不同。
Cu - zn - cr - zr conducting bar alloy and cu - cr - zr end ring alloys used for superpower asynchronous traction motor rotor were prepared by ingot metallurgy . using hardness measurement , tensile test at room and higher temperature , electrical resistance test at room and higher temperature , optical microscopy , xrd , sem , and tem , the mechanical and electric properties and the microstructure of above alloys at different treatment were studied . them were also analysed and explained in theory 采用铸锭冶金法制备了大功率异步牵引电动机转子用导条合金和端环合金，通过硬度测试、室温拉伸、高温拉伸、电导率测定、金相分析、 xrd 、 sem 、 tem等方法研究了不同加工工艺和热处理工艺对上述合金力学性能、导电性能及其组织结构的影响和变化规律，并从理论上进行了分析和解释。
6 5 = 27 . 8 % , o r = 74 . 3 % iacso the second , above alloys not only have good strength and conductibility at room temperature but also have good strength at high temperature . bar alloy can hold o b = 274mpa and o o2 = 250mpa at 350 ? while end ring alloy can hold o b = 200mpa and o 02 = l65mpa at350 ? 研究合金不仅在常温具有很好的强度和导电性，而且具有较高的高温强度，导条合金在350时b仍保持在274mpa左右， 0 . 2仍保持在250mpa左右；端环合金在350时b仍保持在200mpa以上， 0 . 2仍保持在165mpa以上。
