In order to measure instantaneous rotation speed, the rotation speed of the shaft in the spatial coordinate system is investigated and the measurement model for measuring instantaneous rotation speed of rotation mechanism is proposed.

为了测量瞬时转速，对旋转体转速在空间坐标系中的关系进行了研究，并建立了旋转机械瞬时转速测量模型。利用线阵CCD技术设计了一种新型光学瞬时转速测量系统。

So we need consider the effects of the earth curvature. In global integration, the requirement of the data coverage and the computation are comparative high. In this thesis, a moving coordinate system is used to overcome the effects of the earth curvature. And a differential calculation concept is proposed that assumes the difference of geoid calculated between the central point and its marginal point is constant when the integration area is far away from the central point.

论文中提出了利用柱体积分时采用移动坐标系来顾及地球弯曲的影响，并利用差分的概念，设想离计算区域到一定距离后，流动点对计算区域内的中心点和边缘点的影响之差为一常数，并用试验的方法，统计分析了它们对大地水准面的有效积分拓展范围。

In order to improve the calculating precision of geodesic length and azimuth by inverse solution in the new form of geodetic coordinate system, the high-order corrective terms are added and the exact value of latitudinal scale factor of length calculated from geodetic latitude of the calculated points is adopted.

文中对新大地主题解算"的概念没有定义，而是直接引用文献[1，2]的概念，读者若不阅读文献[1，2]，就不清楚"新大地主题解算的概念，建议作者对此进行补充。2。 1、本文探索意在扩大新大地坐标系适用范围，进一步提高解算精度，方案可行，目标明确。
