重心

In virtue of this,some properties of convex polyhedroid are studied and the definite values and extreme values of convex polygon in Euclidean plane are extended to the case in n-dimensional space.

提出n维欧氏空间中广义重心坐标的概念，建立了广义重心坐标下两点间的距离公式，并利用于研究凸多胞形的若干性质，将欧氏平面上凸多边形的一些定值与极值性质推广到n维空间。

To solve the problem above, we develop a new method to filter signal by performing nonlinear transformation of coordinate and filter of function.

其实现的基本思想是：将一曲线分段，求分段的重心，然后将分段中心的函数值赋给重心。

The relation between the center of time gravity of the ultrashort pulse and the carrier phase was studied by using three kinds of pulses,named Gauss,Hyperbolic Secant and Lorentz pulses.The analytical expressions of the relation between them was deduced.

以Gauss、Hyperbolic Secant、Lorentz三种脉冲为例，利用理论推导和数值模拟的方法研究了载波相位对超短脉冲时间重心的影响，并给出了三种脉冲的时间重心与载波相位的解析表达式和数值模拟的图形。

Syntactically speaking, Chinese is a paratactic, personal, topic-prominent and dynamic language while English is strikingly different for being hypotactic, impersonal, subject-prominent and static.

从句法的角度来看，汉语是一种重意合，讲究人称搭配，以主题为重心的动态语言，而英语是一门在很大程度上区别于汉语的语言，它重形合，句子一般以主语为重心，词汇也多采用静态的名词和介词，对人称搭配也没有汉语来得严格。

First of all, the original input data weighted to calculate the weighted center of gravity after the data coordinates, will be moved to the coordinates origin Ping The center of gravity coordinates, re-normalized.

首先 将原始输入数据加权，计算加权后数据的重心坐标，将坐标原点平移到该重心坐标，再作归一化处理。

The purpose is to calculate the butadiene's π MO by golden section relation and to get radio of positive and negative ions,whose coordination number is 4 by regular tetrahedron.

通过提出丁二烯πMO系数比的黄金分割系数和正四面体重心规律的具体应用，用黄金分割关系求出丁二烯的πMO；用重心规律求出配位数为4的正离子与负离子的半径比。

After comparing with previously report, conclusion was as follow: when players use take-off spike movement by single-foot, the strides should increase progressively after observing the ball's direction, and raise the height of jump by getting faster horizontal and vertical velocity of body gravity. In order to avoid increasing the time of take-off, the body gravity is inadvisable to drop so much. In air motion period, player's movement of arm swing will influences the time of spike, if we emphasize the quick offensive, it should reduce the movement of arm swing to decrease the time of spike. When spiking, the joint of elbow should flex by a little range to make forearm powerful.

经由本实验结果与过去研究比较后得到以下结论：选手在执行单脚起跳扣球动作时，助跑的步幅宜在观察球的动向后，采取递增的方式助跑，并加快身体重心水平速度及垂直速度，以提高起跳高度；起跳期起跳脚踏入瞬间身体重心不宜大幅度的下降，以避免增加起跳所花费的时间，影响扣球的节奏及战术的执行；空中动作期时，选手的挥臂动作会影响击球时间，若要强调快速的进攻节奏，宜减少扣球的挥臂动作，以降低完成扣球所需的时间；而击球瞬间肘关节宜保持小幅度的弯曲，以发挥前臂的力量和速度。

Methods The stability of pilot-rescue- equipment depends on its barycenter, so the steeve was analyzed individually to find out its barycenter.

倾覆稳定性取决于吊救装置的重心位置，因此将吊救装置单独分析计算，确定其重心位置。

And the use "unidimensional method" the test human body center of gravity method carries on the comparison to them in the standard posture and other movement posture under bodily center of gravity change.

并采用"一维法"测试人体重心的方法对他们在标准姿势和其它运动姿势下的身体重心变化进行比较。

Malice the desire to score off my neighbour, to enjoy this purification even as I enjoy the clean voluptuousness of the warm breeze on my skin and the cool support of the water ── No Signposts in the Sea.

原句用的是单部句，是全文的重心主题所在，而to enjoy this purification 又是全句的重心所在，因此要放到句末，以符合层进法的修辞要求。

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。
