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。

Whether from commiseration for a woman of so miserable a destiny; or from the morbid curiosity that gives a fictitious value even to common or worthless things; or by whatever other intangible circumstance was then, as now, sufficient to bestow, on some persons, what others might seek in vain; or because Hester really filled a gap which must otherwise have remained vacant; it is certain that she had ready and fairly requited employment for as many hours as she saw fit to occupy with her needle.

或许是出于对这位如此命苦的女人的怜悯；或许是出于对平淡无奇的事情也要故弄玄虚的少见多怪；或许是出于某种难以解释的原因——这在当时和今天都是有的——某些人苦求不得的、别人却可予取予夺、或许是因为海丝特确实填补了原先的一项空白；不管是什么原因吧，反正求她做针线的活路源源不断，只要她乐意于多少钟点，总有很不错的收入。

Whether from commiseration for a woman of so miserable a destiny; or from the morbid curiosity that gives a fictitious value even to common or worthless things; or by whatever other intangible circumstance was then, as now, sufficient to bestow, on some persons, what others might seek in vain; or because Hester really filled a gap which must otherwise have remained vacant; it is certain that she had ready fairly requited employment for as many hours as she saw fit to occupy with her needle.

Commencing from the teaching of common chemistry concept, this topic investigated the function of self-explaining in the teaching of chemistry concept, focusing on exploring whether there exists certain correlation between the level of the students" self-explanation and their academic performances, then tested the variety circumstance of level of students" self-explanation and academic performances after carrying out some training on self-explanation capability. Meanwhile, analyses were made on the exaltation degree to which ths students could improve their academic performances after being trained.

本课题从平常的化学概念的教学入手，探索自我解释(self-explaining)在化学概念的教学中的作用，着重探索了自我解释水平与学生学科成绩间是否存在一定的相关性，进而在通过实施一些自我解释能力的训练后测试学生自我解释水平和学科成绩的变化情况，同时对不同学生经过自我解释能力的训练后的学科成绩的提高程度作了分析。

To fulfill the need of the application of RP technique in medical domain, reverse CAD modeling from medical cross sections is systematically studied in this dissertation. Firstly, Some algorithms related to the research of this dissertation are studied. New algorithms for orientation and inclusion test for simple polygon, an error constrained automatic faring algorithm for B-spline curve and a theorem regarding the termination criterion for subdivision of triangular Bézier patch are proposed. Then based on similarity between contours of adjacent sections, a methodology for surface reconstruction from cross sections is presented. Finally, a virtual measuring method is proposed.
