  1. Abstract : the magnetic moment of a hydrogen atom is calculated by using the solution of the relativistic wave equations. it is shown that the so called total magnetic moment are produced from the electron orbit motion. these results show that the total angular momentum j is actually the relativistic orbital angular momentum

    文摘:利用氫原子的相對論性波動方程解計算了氫原子的磁矩.結果表明，現行量子理論中所謂的總磁矩實際上都是由電子的軌道運動產生的，由此提出了所謂的總角動量實際上是相對論性軌道角動量的看法
  2. The effects of the energy, the angular momentum of particles and the mass quadrupole moment on the orbits of particles are discussed

    討論了粒子的能量、角動量和質量四極矩對于粒子軌道的影響。
  3. According to the law of mass moment of inertia and of momentum moment, the conditions for the complete dynamic balance of rotor inertial forces and moment of inertia in the rotary piston vacuum pump are put forward, with the rotor movement in single cylinder analyzed as basis

    根據質量矩定理和動量矩定理對單缸滑閥真空泵的轉子運動狀況進行了分析，分別提出了轉子慣性力和慣性力矩完全動平衡的條件。
  4. In the motion, the direction of angular momentum vector changes every moment, because there is a torque caused by gravity act on the wheel, then the wheel rotate itself and rotate around the fixed point

    車輪進動實驗：在進動中，角動量的矢量方向不斷改變，是因為受到一個由重力產生的力矩，使車輪在自轉的同時又繞支點轉動。
  5. Just as linear momentum is the product of mass and velocity, so the angular momentum of a body is defined as the product of its moment of inertia and its angular velocity

    正如線性動量是質量和速度乘積一樣，物體角動量也定義為其慣性矩和角速度的乘積。
  6. It must then make fewer turns per second, in obedience to a law of physics called the conservation of magnetic moment ( this is similar to the law of conservation of angular momentum that slows a spinning ice dancer down as he spreads his arms )

    服從稱為磁矩守恆的物理定律，其會減少每秒旋轉的次數（這一定律與角動量守恆定律很相似，花樣滑冰舞者通過伸展自己的上肢來減慢自己旋轉的速度就是利用這一原理） 。
  7. The distributing of the velocity in the intake port and on the port exit and the distributing of the turbulence kinetic energy are get. the momentum moment flow rate is used to scale the swirl. some advices to improve on the port are put forward

    使用ansys的后處理模塊對計算結果進行處理，得到了氣道內、氣道出口的速度分佈、紊流動能分佈等結果，採用動量矩流率對渦流水平進行了評定，並對氣道的改進提出了一定的建議。
