A set of new formulas for computing the position and time of crossover points is presented.

本文给出了一组新的计算交叉点位置和时间的公式，这组公式利用测高卫星精密重复轨道的特点，不需要从星历表中读取每个弧段在赤道上的位置及穿越赤道的时间。

There may be more extra-landm ark noise associated with the measurement of angle NAPg than with the other thre e angles.Since change in SNA is affected by Nasion horizontal displacement,its r epresentation of Point A displacement was questionable.

除了NAPg，其它3个角度的变化基本能反映出颌骨及牙齿在矢状方向的位置改变，但SNA角的变化在一定程度上同时受N点水平向位移的影响，使其反映A点水平向位置改变的可靠性受到影响。

Based on variational principle and split-based interpolation finite element method for fast and accurate analysis of normal mode helical antenna,Combination of genetic algorithm and then load the normal mode helical antenna loaded on the value of lumped elements,Load location,and matching network integrated optimal design parameters,And using Sherman-morrisorr Woodbury formula to quickly solce the load component values and load the changed position of the impedance matrix equation to improve the efficiency of optimized design.

采用基于变分原理和剖分插值为基础的有限元法来快速精确分析法向模螺旋天线，然后结合遗传算法对加载法向模螺旋天线上的加载集总元件的值、加载位置以及匹配网络参数进行一体化优化设计，并采用Sherman-Morrisorr Woodbury公式来快速求解加载元件值和加载位置改变后的阻抗矩阵方程，提高优化设计的效率。

Then this dissertation proposes methodologies and algorithms through which a three-axis NC cutter path can be directly generated from massive data points obtained non-contact measuring devices. At the beginning, a Z-map model is employed to set up mesh points with the principle of Convolution Kernel and Blobby algorithm.

在认真分析闭环伺服系统基本框架的基础上，建立了伺服驱动系统中伺服电机、伺服驱动器等主要部件的数学模型，研究了位置控制器的硬件结构和位置伺服控制策略；通过深入剖析Windows系统的体系结构，提出Windows环境下基于虚拟设备驱动程序的伺服系统稳定控制。

Analogous complexes 3a" and 4a"= CpRu(PPh32, Ar = para-C6H4OMe containing methoxy group at the para-position of gem-diphenyl group were similarly obtained from protonation of the corresponding acetylide complexes via formation of vinylidene intermediate. But only complex 3a'= CpRu(PPh32, Ar2 = fluorenyl is stable in solution, and decomposed to unidentified complex when heated to reflux in THF. Deprotonation of complex 4a in the presence of base gives neutral acetylide complex 6a.

在两个相邻位置的苯基对位位置上接有一甲氧基的衍生物3a&和4a&也可利用类似的质子化反应合成，唯有错合物3a'= CpRu(PPh32， Ar2 = fluorenyl 可以稳定於溶液中，不会进行上述反应，如将其溶於四氢呋喃溶液加热至沸腾则会分解产生无法鉴定的化合物。

The same position of the first plurality and the same position of the second plurality may be the only point on the first and second plurality of acoustic drivers joinable by a straight line.

所述多个第一声学驱动器的相同位置和所述多个第二声学驱动器的相同位置可以是所述多个第一和多个第二声学驱动器上的能被一条直线连接起来的唯一点。

The lid member is hinged to the support member so as to be shiftable between a closure position covering the support member and a toothbrush head on the support member and an opened position providing access to the support member and a toothbrush supported thereby.

使得在覆盖支承件及支承件上的牙刷头部的闭合位置、和为支承件及其支承的牙刷提供通路的打开位置之间可以更换。

There is a need for further studies on the response behavior of torsionally coupled base isolated structures, especially to investigate the effect of torsional coupling on the parametric behavior of base isolated system.

本文首次研究了TMD在存在扭转振动的基础隔震结构上的应用，研究TMD安装位置对结构动力反应的影响，并针对其安装位置进行初步的参数优化。

With Gary Neville ruled out, in effect, for over a year the most United could do was press Wes Brown into service at right-back, where he has contributed stoutly without looking born to the role.

除去加里-内维尔，事实上，在一年多的时间里曼联大多把布朗摁在右边后卫的位置上，他表现的兢兢业业，但是并不是天生就打这个位置的人。

O |-全球最大的阿森纳中文球迷网络社区 The real weakness remains at left-back where Mathieu Flamini has deputized willingly but without the defensive nous that comes with the touchline territory.

真正的漏洞是左后卫，现在马修·弗拉米尼心甘情愿的踢上了这个位置，不过在防守时的位置感稍嫌不足。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
