本研究主要应用劈裂试验，小梁弯曲试验，收缩试验和无侧限抗压试验考察了在普通沥青混合料中掺适量废胶粉后对低温抗裂性能的改善效果。试验结果表明：掺3—5％的废胶粉，可以降低沥青混凝土的低温弹性模最和增大其变形均达1—3倍，玻璃化转变温度也比普通沥青乱凝土的低10℃以上。

Only a single glass transition temperature appeared in the dynamic mechanical spectra indicating atactic copolymers were obtained.

三元共聚物在动态粘弹谱图上只出现单一的玻璃化转变温度峰，是完全的无规共聚物，拉伸强度明显大于常规乳液聚合方法得到的聚合物，耐水性也得到显著提高。

Only a single glass transition temperature appeared in the dynamic mechanical spectra indicating atactic copolymers were obtained.The tensile strength and water resistance are higher than those of samples parpared by conventional emulsion polymerization method.

三元共聚物在动态粘弹谱图上只出现单一的玻璃化转变温度峰，是完全的无规共聚物，拉伸强度明显大于常规乳液聚合方法得到的聚合物，耐水性也得到显著提高。

According to the intrinsic viscosity in dichloroacetic acid at 25℃, the molecular weight of polymers were estimated to be 20, 000～50, 000.Because of the thermal instability of the urea bond in molecular chain, all synthetic polymers began to degrade around 220℃, and had no melting point.

由于模拟聚合物中所含的脲键存在着热不稳定性，所有聚合物的热分解温度都在220℃附近（低于天然动物丝蛋白分解温度），并且所有聚合物样品在熔融之前已开始分解；另外只有分子量比较大的模拟聚合物P4有明显的玻璃化转变（T〓=107℃）。

After that , the comparison of the fertilizable competences of ICSI and IVF on cryopreservated oocytes was studied in this article , in order to establish an optimized method to improve the fertilizable competences of oocytes up to the level of embryos .

和胞浆内单精子注射两种方法对玻璃化冷冻卵母细胞的受精能力进行了比较研究，旨在建立能够进一步提高牛冷冻卵母细胞受精能力的改进方案，使卵母细胞冷冻技术上升到与胚胎冷冻同样成熟的水平。

After that, the comparison of the fertilizable competences of ICSI and IVF on cryopreservated oocytes was studied in this article, in order to establish an optimized method to improve the fertilizable competences of oocytes up to the level of embryos.1 Effects of the reducing injury methods on IVF of cryopreservated oocytesThe result of the three methods, choosing the right time oocytes, using minimum size sample vitrification and culturing after thawing, showed that these ways could partly maintained the fertilizable competences of cryopreservated bovine oocytes.

减轻损伤方案对冷冻卵母细胞IVF的影响使用选择合适时期的卵母细胞进行冷冻；采用最小样本量玻璃化冷冻方法进行冷冻；在解冻后先孵育再进行体外受精等三种方案能够部分维持或恢复冷冻牛卵母细胞IVF受精能力。

With the percent of calcium chloride rises, the way of brittle rupture changes into flexile rupture.
