The results showed that intermidiate 1, 2-propanediol-sebacate of low relative molecular mass was synthesized with toluene-p-sulfoinc acid as catalyst, benzene as watercarrying agent, and of mole ratio of sebacic acid to 1, 2-propanediol of 1:4. The glass-transition temperatures of PPSC were below 0 ℃ which confirmed that PPSC would be in a high-elastic state of ambient temperature and human body temperature. PPSC was a elastomer with moderate crosslinkage, low module and high elongation, and had rapid degradation ratio (degradation degree more than 50%) in phosphate (pH value 7.4) at 37℃.

结果表明，以对甲苯磺酸为催化剂、苯为带水剂，在酸醇比为1，4的条件下可合成较低相对分子质量的中间体癸二酸聚酯二元醇；PPSC弹性体的玻璃化转变温度在0℃以下，于室温及人体温度下处于高弹态；PPSC为适度交联的、低模量高伸长的弹性体，其在37℃、pH值为7.4的磷酸盆缓冲溶液中具有较快的降解性（降解度超过50%）。

The stable polymers was formed through thechemical crosslinking reaction between the hydrolysates of semicellulose and the decompositionproducts of lignin.

半纤维素水解产物与木素的降解产物发生化学交联反应，形成了稳定性极高的体型聚合物，降低了木材的吸湿性，使得压缩变形得以固定，这应该是压缩变形固定的主要原因。

Meanwhile, the differences of prominence about effects of factors and best technological conditions are found by the means of perpendicularity analysis.(2) The properties of semicoke from North Shannxi and coke from Shanxi are compared.

包括对陕北低变质煤煤质特征分析以及干馏失重受干馏温度、热解时间、粉煤粒径的影响规律研究，并运用正交分析的方法得出干馏温度、干馏时间、粉煤粒径对热解失重影响的显著性差异和最佳工艺条件。

After stimulating the sympathetic nerve,it does some stimulation to the organs in abdomen.By keeping the normal hormone's secretion, it delays the women's senilism

并且能刺激交感中枢神经，并对腹腔深部各器官有温热刺激，维持体内性激素的正常分泌，延缓女性早衰，性冷淡等综合症。

The realization of these research goals added thenew contents to the genetic theory and application of sporophytic self-incompatibility inplants.

这3个研究目标的实现，为植物孢子体型的遗传理论提供了新内容，为甘蓝自交不亲和性利用提供了新的方法。

Effects of temperature on degradation of pollen tube RNA by the stylar S-RNase from Prunus mume were investigated, which provided an experimental basis for elucidating the mechanisms of self-incompatibility in Prunus mume.

研究不同温度对果梅花柱S-RNase降解花粉管RNA的影响，为揭示果梅自交不亲和性机制提供依据。

Specific recognition and degradation of stylar S-RNase for self-pollen tube RNA, resulted in the stop of self-tube growth in Prunus mume. The recognition specificity of stylar S-RNase for the RNA weakened with the rise of temperature, consequently regulating the self-incompatibility reaction in Prunus mume.

果梅花柱S-RNase特异性识别并降解自花花粉管RNA，导致自花花粉管停止生长；随着温度的升高花柱S-RNase对花粉管RNA的识别特异性减弱，从而调节果梅的自交不亲和性反应。

Methods: Using to orthogonal design select the emulsifying agent of progest cream,based on the appearance, subtleness, and stability.

以外观、涂展性、细腻性及稳定性为考察指标，采用正交设计，以综合打分的方式筛选乳化剂。

It deliberated that magnesium sulphate and epichlorohydrin affecting on synthetization of starch xanthate, mass ratio of synthetic starch xanthate and Magnesium sulphate was...

研究了MgSO_4和环氧氯丙烷对DX合成的影响，得出淀粉和MgSO_4的重量比为8：1，淀粉和环氧氯丙烷的重量比为10：1，MgSO_4和环氧氯丙烷对黄原酸化程度没有影响，但能增强交联程度和不溶性。

It deliberated that magnesium sulphate and epichlorohydrin affecting on synthetization of starch xanthate, mass ratio of synthetic starch xanthate and Magnesium sulphate was 8: 1, Mass ratio of synthetic starch xanthate and epichlorohydrin was 10 : 1, Magnesium sulphate and epichlorohydrin didn't affect sulphonating extent of synthetic starch xanthate, but did enhance cross extent and nature of insoluble.
