速度

Since the phase velocity and Q-factor both are functions of complex velocity, their values can be computed easily.

而复速度和品质因子又是复速度的函数，从而便可很容易的得出。

For every mode of Lamb waves, the magnitude of phase velocity between the two models has the turning point.

3对于Lamb波的每个模式，煤粒负载模型相速度与单层模型相速度的大小关系存在一个转折点。

Also, to study the subluminous phase velocity in optical field is meaningful and fundamental from the view of basic research in optical theory.

另外，相速度本身是光场传播理论中的一个基本问题，研究光场低相速度区存在的一般规律，也是一个有意义的基础性研究课题。

The surface waves propagate with a phase velocity which is always less than the velocity of ectromagnetic waves in free space.

面波传播速度的阶段，始终是比ectromagnetic波在自由空间速度减少。

The research leads to following conclusions: A The age of the ferromanganese contacting with the upper phosphate layer is 14.9 Ma; B The crust had been grown continually without sedimentation interruption since 14.9 Ma, suggesting that it can be used to rebuild the environment of palaeo-ocean and palaeo-climate from 14.9 Ma to 0 Ma; C The sedimentation interruption between the ferromanganese and the upper phosphate layer lasted around 4 Ma; D Between 19 Ma and 22.7 Ma, great phosphatization event happened in this area, which might cause the sedimentation interruption from 22.7 Ma to 14.9 Ma; E The ferromanganese crust began to grow from 75 Ma.

对超微量Sr同位素测试得到的富钴结壳磷酸盐年龄进行分析认为：(1)上部富钴结壳与上层白色磷酸盐化层接触部位的年龄为14.9 Ma；(2)自14.9 Ma以来，结壳的生长是连续的，沉积间断发生的可能性非常小，该样品可以用来进行14.9 Ma年以来古海洋、全球变化的重建工作；(3)上层白色磷酸盐化层与其上部的富钴结壳之间存在4 Ma的沉积间断；(4)19 Ma~22.7 Ma左右在该区发生过大规模的磷酸盐化作用，磷酸盐化作用可能造成磷酸盐化时期(19 Ma~22.7 Ma)和之后4 Ma(19 Ma~14.9 Ma)富钴结壳的沉积间断；(5)结壳的初始生长年龄在75 Ma左右；(6)老结壳的生长速度要远低于新结壳的生长速度。

Lines are induced on the surface of a photosensitive glass by focused femtosecond laser transverse writing with scanning velocity in a wide range of 40-1800 μm/s. The formed lines are analyzed using scanning electron microscope and optical microscope.

利用聚焦飞秒激光的横向直写方式，采用宽的扫描速度范围(40-1800 μm/s)，在光敏玻璃表面上诱导了直线结构，并扫描电子显微镜和光学显微镜分析了形成的直线，发现随着扫描速度不同，形成的直线具有三种不同的形貌。

If she falls below 140 strides per minute she'll pick up the pace.

如果她速度降至每分钟140步以下，她会马上提高速度。

Pitot tube allows an indirect measurement of speed by determining the dynamic pressure from the difference between the total and static pressure.

空速管提供了一种间接测量速度的方法，它是通过测定全压和静态压强差值的动态变化来测量速度的。

A pitot tube is a pressure measurement instrument used to measure fluid flow velocity. The pitot tube was invented by the French engineer Henri Pitot in the early 1700s and was modified to its modern form in the mid 1800s by French scientist Henry Darcy. It is widely used to determine the airspeed of an aircraft and to measure air and gas velocities in industrial applications.

速度感应器，俗称空速管，最早就是法国工程师 Henri Pitot 先生发明，并在一个世纪后由另一位法国工程师 Henry Darcy 先生改进而成为现代形式的重要器件，广泛用于探测气体或液体的速度变化，并把数据传到给控制中心。

Velocity formula and acceleration formula of point in the plane graph is proved by means of complex vector ,and a simple method to obtain the velocity and acceleration is proposed.

研究刚体的平面平行运动，用复矢量方法推导了平面图形内各点的速度、加速度关系式，给出了求解平面图形内各点速度、加速度的简捷方法。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down
