Secondly, in our methods, the essential geometry of the image single axis geometry may be specified by six parameters and this may be estimated from one conic and one fundamental matrix (a total of 12 parameters) or may be minimally estimated from two conics (a total of 10 parameters).

本文证明了单轴旋转运动的不变量可以通过一个基本矩阵和一条二次曲线来确定，在这种情况下，由于基本矩阵的自由度为7，二次曲线的自由度为5，所需确定的参量个数仅为12，大大减少了不变量的计算量；本文同时证明单轴旋转运动的不变量可以通过最少两条二次曲线来确定，在这种情况下所需确定的参量个数仅为10，该方法是目前同类算法中参数最少的；本文提出了用多条二次曲线求解单轴旋转运动的不变量的最大似然估计算法，其所需确定的参量个数为6+2n，其中n为二次曲线的个数，该公式更深刻地反映了二次曲线与不变量的参数关系。

The effects of FPL andits three ingredients on growth of ovary,on micro-and ultra-structure andAlkaline phosphatase activity of endometrium,on structure andkeratinization rate of exfoliated cells in vaginal epithelium in mice,onmicrocirculation in rat and on uterine kinesis in rabbit were respectivelyobserved by the techniques of light and electron microscopes,histochemistry,microcirculation and organ cinetography.The results have confirmed themechanism of FPL for the sterility caused by ovary standstill and persistentcorpus luteum to be as follows:(1) a weak estrogen-like role which canprompt development of ovary,proliferation and secretion of endometrium andvaginal epithelium and cornification of exfoliated cells in vaginal epithelium;(2)enhancing AKP's activity of endometrium;(3)improving microcirculation;(4) exciting uterus.

In order to decrease visual delay in virtual reality,we studied and analyzed the testing results of all sorts of human being head motion .

为了克服虚拟现实系统中的视觉延迟现象，在对各种头部运动规律测试结果分析研究的基础上，提出人的头部运动是具有高斯-马尔可夫特性的随机过程，建立了头部运动的随机数学模型，设计了基于卡尔曼滤波和测量数据预处理技术的头部未来位置预测算法。

In order to decrease visual delay in virtual reality, we studied and analyzed the testing results of all sorts of human being head motion. We put forward that the head moving of human being is a Guass-Markov stochastic process and constructed a stochastic mathematics model for head motion. We also proposed an effective algorithm for head-moving prediction based on Kalman filtering and preprocessing of the measured data.

Dynamic motion study Deep tow system often works under complex sea condition, so the vehicle responses to draw-in and let-out cable are studied, the response to heaving is studied too.

缆体系统动态运动分析深拖系统常常工作于复杂的海况条件下，拖体一般是不带动力的，仅靠母船的机动和支持保持拖体的定深和避碰，因此，本文在缆体系统动态分析的基础上，研究了拖体对缆顶端的收放缆运动及垂荡运动的响应。

According to our assumption, the ether is carried by the motion and takes a part in it. A light wave passing near the wheel would have a different speed when the wheel is at rest than when it is in motion.

根据我们的假定，以太被轮子的运动所带走，并且是参与运动的，通过轮子旁边的光波的速率会因轮子的静止或运动而有所不同。

Moldeling and simulation of bubble motion caused by ultrasound using MATLAB The model to describe bubble dynamic motion caused by ultrasound was presented, which included the effects of fluid viscosity, surface tension and vapor pressure of the solvent.

超声空化气泡运动过程模拟及模型的求解建立了超声作用于均相液体中空化泡运动的动力学模型，模型中考虑了液相的动力粘度、表面张力和溶剂的蒸汽压对空化泡运动特性的影响，用MATLAB对建立的普遍化的模型方程进行了数值求解和过程模拟。

Linear motor is a kind of equipment for converting electrical energy into linear movement use. In most occasions where need converting rotary movement into linear movement, linear motor shows its superiority. It makes many in-between transferring machine unnecessary. Therefore, the whole system runs more steadily. In addition, thanks to the reducing of the in-between machine, the friction wastage of the whole system is reduced and the efficiency of the whole system is improved.

直线电机是一种将电能直接转换成直线运动机械能的驱动装置，在许多需要由旋转运动转换成直线运动的场合下使用，它可以省却中间机构，从而使装置得以简化，减少了维护的工作量，提高了系统的可靠性，且易于控制，在合适的使用场合下，还可以提高整个系统的效率。

The purpose of this study was to evaluate the changes on the tongue movement during swallowing before and after orthodontic retraction of anterior teeth using ultrasound technique. The subject consisted of four men and nine women, with a mean age of 21.3 years old. The subjects were undergoing orthodontic treatment with extraction, and there were at least 3mm space left on each side between lateral incisors and canines.

在齿颚矫正治疗时，常常利用拔牙的方式让前牙往后方移动，而这样的移动是否会影响舌头的运动及功能则有待验证；本研究的目的是使用B+M模式口腔超音波防震扫描技术，去评估接受拔牙治疗之矫正患者，在前牙后退完成之后，舌头吞咽运动的时间和振幅是否会改变，并检测前牙距离、角度的改变比率和舌头吞咽运动改变比率之间的相关性。

In video sequences, the objects we are interested in are those which are of self-movement, so most of video segmentation refer to the segmentation of self-movement objects. This paper also mainly discusses the segmentation of self-movement objects.

由于在视频序列中，人们注意及感兴趣的主体，一般是具有自主运动的物体，所以现有的视频分割算法绝大多数指的是视频中运动对象的分割，本文也主要讨论视频中运动对象的分割。

The split between the two groups can hardly be papered over.
