查询词典 conservation

Based on the conservation principle of linear and angular momentum,the method derives the equations of the mass and mass center as well as inertia tensor of the new end-effector for the manipulator handling the unknown object.

1引言由于自由飞行空间机器人本体的质量随着载荷及燃料的消耗而发生变化，而目标的惯性参数往往是未知的，因此在运动控制时，必须进行参数辨识。

Vector nature of angular momentum, precession, conservation of vector angular momentum (its transfer between parts of a system), nutation.

角动量的矢量特性，进动，角动量守恒(它在系统内部之间的转移)，章动。

The tangent space and normal space of the robot motion curve is constructed by using Newton-Euler orthogonal method, which satisfies the restrictions of linear and angular momentum conservation of free-floating space robot system. An analytical expression of joint actuation torque in the floating state is given by using this method.

根据空间机器人自由漂浮状态时系统动量守恒的特点，采用Newton-Euler正交方法构建了满足系统动量守恒约束条件的空间机器人运动曲线法空间与切空间基底，并以此基础得到了自由飘浮状态下的空间机器人关节力矩的显式表达式。

In the teaching of central field, we should pay attention to turning the relative motion of two - body into one dimentuonal radial motion by introducing two physical concepts of reduced mass and effective potential energy, and we should also pay attention that the area law is the geometrical description of the conservation of angular momentum in the central field.

在有心力场教学中，应着重强调指出：通过引入折合质量和有效势能这两个物理量，把二体相对运动问题转化为单体沿径向的一维运动问题；以及面积定律是质心在有心力场中角动量守恒的几何描述。

However, the Big Bang does not explain many things, including the uneven distribution of matter that results in "voids" and "clumps," or the retrograde motion that must violate the Law of Conservation of Angular Momentum.

然而，大爆炸并不能解释许多事实，包括物质分配不均，结果造成一些"虚空"和"实体"；而且"逆行运动"必然违反角动量守恒定律。

But I think we should also enhance people's awareness of energy conservation.

你说的有道理，但是我认为我们应该提高人们节约能源的意识。

To encourage more people to join the ranks of energy conservation.

鼓励更多的人加入节能的队伍里。

This will not only improve the health indicators, but also with the role of energy conservation.

这不仅将改善其健康状况的指标，而且还与节约能源的作用。

So the study of energy conservation of heating is very necessary.

因此，进行供热节能的研究是非常必要的。

The two nations will cooperate on research and development of energy conservation.

这两个国家将合作进行能源保护的研究与开发。

All this to say that I'm glad filmmaking hasn't become completely ironic. I can enjoy an ironic film as much as the next person, but they usually involve a message of some sort. One that's delivered in a smirkingly clever way that requires little in the way of talent.

所有这些都是说，我很高兴电影制作没有变成完全讽刺艺术，我可以和下一个人一样享受讽刺电影的乐趣，虽然他们经常会被划归到一定级别，技术方面不需要很高的才能。
