A new kind of copolyetherimide is synthesized, and effect of contents of this kind of COPEI resin on morphology of blends of COPEI/the diglycidyl ether of bisphenol A(the Epikote 828)/ 4,4'-diamino diphenyl sulphone and preparation of epoxy resin microspheres are researched .

采用共缩聚方法合成了一种新型聚醚酰亚胺，通过改变它在COPEI/双酚A二缩水甘油醚型环氧树脂(E828)／二氨基二苯基砜共混体系中的用量，考察了对共混体系的相结构以及对制备环氧树脂微球的影响。

Multiple experiments include whole sphere and sphere with cracks due to some spheres have a few cracks in the shell equatorial plane after welding. Then, the nominal compression stress-strain curves corresponding to different included angles θ between horizontal plane and welding line were plotted.

由于其中某些空心球在焊接时出现了孔洞，故分别做了完整和焊接出现孔洞的两种情况下的多组实验，得出了焊缝与水平面夹角θ成不同角度时压缩的名义应力－应变曲线。

Gibreel, the tuneless soloist, had been cavorting in moonlight as he sang his impromptu gazal, swimming in air, butterfly-stroke, breast-stroke, bunching himself into a ball, spreadeagling himself against the almost-infinity of the almost-dawn, adopting heraldic postures, rampant, couchant, pitting levity against gravity.

加百列，这个不和谐的独唱演员，兀自在月光下的天空跳跃翻滚，一边咏唱着他的即兴gazal，一边在空气中划游，时而蝶泳，时而蛙泳，一会儿蜷缩成一个球，一会儿又尽情舒展开，向无限的黎明，用一种庄严的姿态，时而高昂，时而俯伏，轻率地和万有引力较着劲。

A pulsar is a celestial object that emits light in short burst a pulsar in the crab nebula flashes at a rate of 30 times/s,suppose the light pulses are caused by the rotation of a spherical object that emits light from a pair of diametrically opposed "flashlights" on its equator.

脉冲星是一种以短爆发形式辐射光的天体。假设球型天体赤道面上有一对"发光塔"，并且这对发光塔的联线构成赤道面的直径，进一步假设光脉冲产生于球形天体的转动，那么巨蟹座星云中的一个脉冲星的闪光频率是每秒30次。
