直线运动

Descartes and Gassendi were the first to insist that inertial motion must be rectilinear motion and that bodies move in circles or curves must be constrained by some external cause.

笛卡儿和加森迪首先坚持惯性运动是直线运动，在圆或曲线上的运动必被某些外因所限制）Such bodies， Descartes

D: Well the law of inertia says that something in motion will tend to stay in motion, and what's more, to move in a straight line.

惯性原则就是：运动中的物体要保持运动的状态，同时保持直线运动（惯性守则好像不是这么说的吧，请参看楼上的）。

It is a pity that the actual motion blur direction in the blurred image is often unknown.

在曝光的瞬间，造成图像模糊的被摄景物与相机的相对运动，虽可近似作为直线运动来处理，但模糊图像中的运动模糊方向未知。

Static motion study Uniform rectilinear motion is the basic motion of deep tow system, it is also named static motion.

缆体系统静态运动分析匀速直线运动是深拖系统的基本运动状态，也是缆体系统研究的基础，称静态运动。

Therefore the plunger is in both rectilinear motion and circular motion.

柱塞在运动中既做往复直线运动，同时还做圆周运动，故磨损均匀，使用寿命延长。

It is also a familiar fact that a force is required to slow down or stop a body which is already in motion,and that a sidewise force must be exerted on a moving body to deviate it from a straight line.

要使一个已经运动的物体慢下来或使其停止运动就需要作用力；要使该物体偏离直线运动，就需要横向作用力，这也是大家所熟悉的事实。

That a force is rettulred to slow down or stop a body which is already in motion, and that a sidewise force must be exerted on a moving body to deviate it from a straight line.

要使一个已经运动的物体慢下来或使其停止运动就需要作用力；要使该物体偏离直线运动，就需要横向作用力，这也是大家所熟悉的事实。it 是形式主语，代替 that 引出的两个主语从句。

The motion of the fluid flowing through a SKstatic mixer in laminar flow can be resolved into rotary motion and straightline motion, so we can respectively calculate the flow resistance of the two motions.

将流体在静态混合器中作的层流流动分解为直线运动和旋转运动，然后分别计算这两种运动在流管中的流体阻力，并将两者相加后得到SK型静态混合器中液体层流流动时流体阻力的计算式。

The main idea of the simulation is adopting Monte Carlo method and the classical over barrier model to simulate the randomicity of the charge exchange processes between projectile and metal and the dispersing of projectile's continuum movement. In each step, the movement of projectile is considered to a uniform acceleration.

本论文模拟的基本思想是在经典过垒模型下，采用蒙特卡罗方法来模拟入射离子与固体间电荷交换过程的随机性，并将入射离子连续的运动过程离散化，在每一个步长中，将入射离子的运动近似看成是匀加速直线运动。

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。
