The results indicate that the hexyl branches content has dramatically effects on the thermal properties and crystallization behavior. The shear effect on WAXD results is less than that on SAXS results which indicates that PEcO melt is relatively stable in a definite structure scale.

对剪切场下不同辛烯含量的PEcO的结晶研究发现：剪切对广角测试范围的结构影响较小，对小角测试范围的结构影响较大，说明乙烯-辛烯共聚物熔体在一定尺度范围的结构是比较稳定的。

A quadrilateral distortion metric was proposed, which considered both of element minimal angle and warpage. An mesh smoothing approach of combining Laplacian method and μGA for quadrilateral mesh was presented, which could improve the mesh quality significantly without effect the algorithm's performance.

提出一种综合考虑单元最小角和翘曲的四边形网格质量评价标准，以该标准为优化目标，提出了一种以面积为权值的Laplacian方法与小种群遗传算法相结合的网格光顺方法，在兼顾计算效率的同时，可有效地优化网格形态质量。

Theoretical analysis and simulation shows that the direction driving motor accelerates first, and then decelerates to compensate for the eccentricity when the satellite is deviated from laser center with a certain distance, and reacquires the tracking satellite. The needed time from reacquisition to tracking is affected by motor acceleration, telescope′s detecting precision, and detector′s response and treatment time, and the effect of detector precision on the reacquisition and re-tracking time is greater, as a result, the detector response and treatment time is decreased to the least.

理论分析与仿真结果表明，当卫星偏离光斑中心一定距离时，指向驱动电机先加速后减速，补偿这个偏心，重新捕获跟踪卫星；重新捕获到跟踪所需时间受电机加速度和望远镜探测精度以及探测器响应处理时间影响，其中探测器精度对重新捕获到跟踪所需时间影响较大，探测器响应处理时间要减小到最小；为了使从捕获到跟踪过程中卫星始终在扫描光斑范围内，经纬仪驱动电机的最小角加速度为25.5°/s2。
