Dicyclopentadiene dioxide was hardly cured by amines or acid anhydrides alone, but can be well cured by acid anhydrides mixed with alcohols. The curing process using different amounts of maleic anhydride and glycerol were studied, and the influence on gel time and temperature-deformation curve were determined. Although dicyclopenta-diene dioxide is a diepoxide compound, the cured resin formed a more rigid molecular chain, therefore a plastic which shows no glass transition point before the decomposition...

Dicyclopentadiene dioxide was hardly cured by amines or acid anhydrides alone, but can be well cured by acid anhydrides mixed with alcohols. The curing process using different amounts of maleic anhydride and glycerol were studied, and the influence on gel time and temperature-deformation curve were determined. Although dicyclopenta-diene dioxide is a diepoxide compound, the cured resin formed a more rigid molecular chain, therefore a plastic which shows no glass transition point before the decomposition temperature (ca. 300°) may be obtained under optimum amount of curing agent and proper curing conditions.

二氧化双环戊二烯难于被胺或单独的酸酐所固化,但能很好的被酸酐与醇所固化。曾采用不同量的顺丁烯二酸酐及甘油进行固化,并确定了对凝胶时间及温度形变曲綫的影响。二氧化双环戊二烯虽是一种双环氧化合物,但由于能形成较为殭硬的分子链,因此在适当的固化剂用量及固化条件下,能得在分解温度(约300℃)前不出现玻璃化转变的塑料。

In this article, dynamical features of non - equilibrium phase transitions are dis-cussed, taking the physical problems of OPO and laser processes as two examples. The phase transition point is found to be the point of sudden change from a stable nodal point to a saddle point. The role of fluctuations and dissipations in such phase transi-tions is elucidated, and critical exponents analogous to those in the second order phase transition are found (β = 1/2, γ4 = 1).

本文就光学参量振荡和激光两个物理问题,讨论了非平衡态相变过程的动力特点。相变点是由稳定结点状态突变到鞍点时的转变点。说明了涨落和耗散在相变中所起的作用,得到第二类相变的临界指数(β=1/2,γ=1)。

Near the N→SA transition point, recent observations show that the anomalous increase in the volume viscosity is much greater than that of the shear viscosity. This is explained in terms of the time correlation function for viscosity. The reason for the disagreement between the experimental results and the Brochard's theory is also given.

本文由粘滞系数的时间关联函数表达式,得到了实验观察到的现象:在液晶N相→S_A相转变点附近(T→T_s_A),体粘滞系数的反常发散比切变粘滞系数反常发散要大得多。说明了Brochard等人的理论中,不能解释此实验的原因。
