" The first law, also called the law of inertia , states that if a Body is at rest or moving at constant speed in a straight line, it will continue to do so unless it is acted upon by a force."

第一定律说，如果物体处在静止状态或者沿直线做等速运动，那它将继续保持这种状态，除非受到力的作用才会改变。

A body in motion remains in motion at a constant speed in a straight line without the action of an external force.

没有外力的作用，运动中的物体就连续作匀速直线运动。

By adding a suffix, we can force the type of a literal integer constant to be type long or unsigned or unsigned long.

通过增加后缀，能够强制将字面值整数常量转换为 long、 unsigned 或 unsigned long 类型。

The target of the control system is to maintain constant normal force and tangent speed when following or deburring a workpiece.

最后，进行了边缘跟踪及打毛刺实验，分析了在不同速度及不同正压力下，对力均方误差的影响。

While the experimental side force distribution over a slender body with a blunt ogive nose is basically consistent with the curve of the analogy predicted, and the characteristic points and half cycle of the experimental curve are basically constant with the roll angle changing 360°. But the local maximums in the curve are not the results as the analogy predicted, which is an important flow feature of 3-D slender body than that of 2-D cylinder.

而钝头拱形细长体在大迎角下的截面侧向力分布与脉冲起动横流比拟方法预测的侧向力曲线的形状是基本相同的，而且随着滚转角旋转360°，截面侧向力分布曲线的特征点和半周期基本保持不变，即它们都基本上不受滚转角变化的影响；但是截面侧向力分布曲线极值点形成的原因却是不同的，这是细长体绕流区别于二维圆柱绕流的一个重要特性。

In the investigation of micromagnetism, in-plane magnetoresistance and in-field magnetic force microscopy on a series of permalloy planar wires were performed. Here, the wire length and thickness are kept constant, 20μm and 30nm, respectively. The width of the wire spans from 10 to 0.1μm. The magneto-transport behavior and magnetic configuration are quite different regarding their widths, corresponding to the aspect ratio.

在研究微磁学时，我们以平行膜面磁阻的量测和施加磁场下观察磁区的磁力显微来从事一系列镍铁合金毫微米线的磁矩翻转研究，这一系列毫微米线的线长和厚度分别固定为20微米和30奈米，线宽则由10微米变化至0.1微米，线宽的改变将造成磁电传输行为和磁区结构有截然不同的结果。

But, in the every phase of constant developing of the globalization, the leading force varies from strength to weakness, from single-pole to multi-poles with the changes of political and economical conditions.

资本主义主导的全球化由特殊趋向一般，即由单一资本主义为主导的全球化趋向非资本主义的全球化；由单向转向双向，即由西方发达国家对东方发展中国家的单向扩张转为东西方国家的互动。

This problem was addressed by developing "polarizable force fields" [1][2] or using macroscopic dielectric constant .

这个问题可由极化力场来解决。或者利用大尺度介电常数。

Why does the field force is in inverse proportion to the square of the distance between the two masses, but not to three or four power of ones and to prefigure that the constant G of the gravitation isn't invariant.

概述：此文章描述了引力的动力过程，阐述了引力质量是惯性质量的一种表现形式；场力为什么与作用距离的平方成反比，而不是与三次方、四次方成反比；并预示了万有引力常数G并不是真正不变的常量等等。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
