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 -
In the interest of adapting big size in radial direction, higher precision, higher angular rigidity, less moment of inertia, higher dynamic capability in the three - anxis simulation test turntable. researching the angular rigidity of the wire race ball bearings in axes direction, the adjustment mode and adjustment quantity to shafting, and analysing the contact stress of bearings in work is very necessity
為了適應某些模擬轉臺研製中關于剛度高，轉動慣量盡量小，動態特性要求高等特殊要求，研究鋼絲滾道球軸承的軸向支撐剛度，軸系調整方式及調整量，以及該軸承在工作中的受力及應力狀況十分必要。 -
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。 -
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。 -
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。 -
As the motor of hev, it is required to meet the need of the frequency of start - up / shut - down, step - up / speed - down, the radical change between higher angular moment during low speed or climbing and lower angular moment during high speed, the enablement of regenerative braking
作為混合動力電動汽車用的電機要求能夠滿足頻繁地啟動停車、加速減速，低速或爬坡時要求高轉矩，高速行駛時要求低轉矩的大范圍變速，以及實現再生制動的需要。 -
Studying the techniques to speedup the ray - tracing method, introducing the methods which are popular for the moment of the partitioning of the urban cell, including space volumetric partitioning, angular z - buffer technique and triangulation, through the comparative advantages of these methods, and combining with the technologies of computer graphics, we get a new efficient ray - tracing method - - a ray - tracing method based on the octtree technique
重點闡述了其加速技術，介紹了現有的分區技術，包括直接的下方形分區、角分區以及三角形分區，通過比較、分析這些分區方法的優點與不足，並結合計算機圖形學技術，我們得到了一種新的、更加方便、快速、有效的射線跟蹤演算法? ?射線跟蹤八叉樹演算法。 -
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） 。
