momentum vector 中文意思是什麼
momentum vector
解釋
動量矢量-
Angular momentum is an axial vector quantity.
角動量是一種軸矢量。 -
If the wheel is rotating counterclockwise, its angular-momentum vector is directed eastward.
如果輪子是逆時針方向旋轉，其角動量矢量的方向朝東。 -
Orbital angular momentum vector
軌道角動量矢量 -
The results show that binding energies per nucleon at each density and various asymmetry parameters fulfill the empirical parabolic law and the asymmetry energy is density dependent. it is found that both scalar and vector potentials of neutron in the neutron rich nuclear matter become stronger although the isospin dependence is not stronger. we compare our results with those in a simple method, where the dbhf nucleon self - energies are extracted from the momentum dependence of the single - particle energy
首先我們要求在每一個密度及各種不對稱系數的核物質中，相對論平均場（ rmf ）計算出的核子標量與矢量自能與dbhf計算出的標量與矢量自能一致，從而得到在rmf下的密度依賴的有效介子核子耦合常數，包括同位旋標量介子。 -
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。 -
In some ways, an electron is just like such a spinning sphere of charge ? an electron has a quantity of angular momentum ( its “ spin ” ) and an associated magnetism, and in an ambient magnetic field its energy depends on how its spin vector is oriented
就某種意義而言，電子可類比於一個旋轉的帶電小球：它帶有角動量（就是自旋）以及伴隨而來的磁性，而它的能量是由自旋向量與外加磁場的關系來決定。 -
And the technology can also control the vector of a primary jet, the ratio of momentum between the synthetic jet and the primary jet is a main influence factor, and the vectoring control of primary jet is also effected deeply by the position and the frequency of actuators
應用合成射流技術可以有效控制宏觀低速流流動方向，其控制強度由宏國防科學技術大學研究生院學位論文觀流動與合成射流的動量比決定，而合成射流激勵器的工作頻率以其布置位置對主流的控制效果影響很大。
