The synthesized PCU was then characterized by infrared spectroscopy, differential scanning calorimetry, thermogravimetric analysis, small-angle X-ray scattering, and tensile strength measurement. The IR showed that the polymer synthesized by the above two methods both have the polycarbonate-urethane structure and the tensile measurement showed good mechanical performance of the polymer. The DSC and TGA data showed that there is an obvious soft-hard glass transition area, which indicated the existence of the micro-phase separation structure. The extent of the phase separation was affected by the ratio of starting materials, the molecular weight of PCD, and the polymerization method. The decomposition upon heating was observed in two steps. SAXS result showed that the radius (r_2), the distance between domains (d_2), and gyral radius (R_2) of hard segment micro-domain were fairly affected by the starting materials ratio and soft segment content.

IR结果表明两种方法合成的聚合产物均具有聚碳酸酯聚氨酯的结构;拉伸实验表明聚合产物具有良好的力学性能;DSC、TG结果表明,聚合物呈现出较为明显的软硬段玻璃化转变区,表明存在微相分离的结构,相分离的程度受原料配比、软段分子量、聚合方法的影响,其热分解分为明显的两个阶段; SAXS结果表明,聚合物原料配比、软段含量的变化对硬段微区回旋半径R_2,微区间距d_2,微区半径r_2影响不大其值分别为9.5(A|°、29、7.4,但对软段的微区半径及间距影响较大,随着软段含量的增大,软段微区的半径r1和间距d1都增大。

The tensile property was improved and then stable with the increasing content of coupling agent, however, the crupture ratio up and then down. And the tensile strength increase stey by step and electric insulation property is up and then descended with the addition of radiation agents.

结果表明,随着阻燃剂含量的增加和粒径超细化,其阻燃性能不断得到提高;而随着偶联剂含量的增加,其拉伸强度逐渐增大到一定程度后趋向稳定,断裂伸长率则先增大后下降;随着辐照剂量的增大,拉伸强度逐渐增大,电气绝缘性能先上升后下降。

Based on a lot of experiments, it shows the distinct error between classical theory curve which express the relation of cell diameter, cell density and foam tensile strength , tensibility tensile product and re-spring degree and experiment curve. It also can't explain the relation of hole degree , area of cell wall with above four mechanics parameter. But the sub-cluster scale theory was demonstrated successfully to explain the relation of cell structure and foam mechanics property on different mold temperature, mold pressure, mold period and different chemical blowing agent, blowing activator content.

通过大量的实验结果理论分析表明:以往的经典理论存在着很多不足之处,它不能有效地解释孔径、泡孔密度与抗拉强度、断裂伸长率、断裂功、及回弹率之间的理论曲线与实验曲线之间的偏差,也不能解释空隙度、泡孔壁厚与上面四者之间的关系,而群子标度理论则成功地论证了在不同模压温度、模压压力、模压时间及不同用量发泡剂、发泡促进剂条件下泡体力学性能与结构之间的相关性。

The results indicate that the formation of loess vertical joints can be divided into two phases:① the formation of inner fissure, i.e. in the beginning of deposition, the undulation of terrain leads to uneven distribution of loess, then when it rains uneven collapsibility generates, which leads to generate inner fissures ;② the stage of fissure extension, namely loess continues deposition after the inner fissures have been formed, the increasing of the top pressure makes the top of inner fissure lie in the state of tensile stress, so, when the stress reaches its tensile strength, the inner fissure extends along the vertical direction and then becomes a vertical joint.

结果表明黄土垂直节理的形成可分为 2 个阶段:①内裂隙形成阶段,开始沉积时,由于地形的起伏导致黄土厚度上的分布不均匀,在降雨时产生不均匀湿陷,从而导致产生内裂隙;②裂隙扩展阶段,内裂隙形成后黄土继续堆积,顶部压力的增长致使裂隙顶部土体受到拉应力作用,当达到其抗拉强度时裂隙就会沿竖直方向产生扩张而形成垂直节理。

It indicates that the damnification morphology of K9 glass is cleavage damage, the reason of which is that the hoop tensile stress overtops materials'tensile strength. And the materials'damage threshold is inversely proportional to irradiation time.The mathematical model of in-band CW laser irradiating optical material is established.

结果表明:K9玻璃材料的损伤形态为解理破坏,破坏的原因是环向拉伸应力大于材料的抗拉强度,且材料的损伤阈值与辐照时间反向相关,即激光功率密度越高,造成破坏所需的时间越短。
