查询词典 inertial motion

If a particle is moving accelerated, the sum of the inertial reactions of the particle to the objects which force it to produce the accelerated motion is called the inertial force of the particle.

从质点组相对运动动力学方程出发，考虑每个质点受到的惯性力，推导出非惯性系的动能定理，并在此基础上对机械能守恒进行研究，给出了惯性力为保守力的条件。

However, most of these investigations focused on the rotating beams or plates undergoing a prescribed large overall motion, where the effect of large overall motion of the reference frame on elastic deformation was considered but at the same time the beam's elastic deformation couldn't influence the large overall motion of the reference frame because the large overall motion is known a priori. In fact, this kind of problem on the dynamic stiffening is a structural dynamics problem in a non-inertial frame.

值得指出，上述这些研究工作都局限于大范围运动为已知情况下的非惯性系下柔性体的动力学性质，实质上是一个非惯性系下的结构动力学问题，只考虑了大范围运动对变形运动的影响，而没有充分考虑到大范围运动和变形运动之间的相互耦合作用，这种耦合作用是单向的。

The scale analysis on planetary scale motion in the tropical atmosphere shows that the equilibrium between the pressure gradient force and Coriolis force in the meridional direction is easily established, which is known as the zonally semi-geostrophic motion The semi-geostrophic adaptation process in which the inertial gravity waves play an important part is relatively quick The evolution process after the semi-geostrophic adaptation process is slow and controlled by the Kelvin waves and long Rossby waves

对热带大气行星尺度运动所做的尺度分析和物理分析表明：热带大气的行星尺度运动在y方向容易实现气压梯度力与Coriolis力的平衡，它称为纬圈的半地转运动。半地转平衡的建立过程，也就是半地转适应过程相对是很短暂的，它不需要考虑f=β0y随y的变化，因而主要依靠惯性重力波为频散；而半地转平衡建立后的演变过程相对是很缓慢的，它主要受Kelvin波和Rossby波控制。

While the frequency can be as high as N when the particle motion is vertical, it cannot be lower than the Coriolis frequency f. In this limit, the particle motion is horizontal in 'inertial' circles, expressing the tendency for steady rectilinear motion with respect to a nonrotating reference frame.

虽然频率可高达为N时，粒子的运动是垂直的，它不能低于科氏频率楼在此限制，粒子议案是水平在'惯性'界，表达为稳定直线运动的趋势关于一nonrotating参照系。

Teacher, Shen mentioned formula replicability reasoning using mathematical methods, often with red, yellow and blue chalk in turn show the hands of this teacher, Shen, colored chalk, such as beating of the notes, images, vivid, so that we are both relaxed and learn together happy; Shen teacher also used chalk powder into the suspension liquid foam, and emulsion, the solution can be compared; to chalk on the throw, drop to indicate what is the role of inertial motion and gravity; is to compare chalk down chalk placed on the desktop Pressure Size ......

沈老师讲到公式的举一反三，在用数学方法进行推理时，往往用红、黄、蓝粉笔依次展示，沈老师手中这彩色粉笔如跳动的音符，形象、生动，使我们学起来感到既轻松又愉快；沈老师还用粉笔灰泡成悬浊液，与乳浊液、溶液进行比较；将粉笔上抛、下落来说明什么是惯性运动和重力作用；正倒放置粉笔来比较粉笔对桌面压强的大小……总之，每一节每一课，沈老师的粉笔都有妙用。
