spherical radiation 中文意思是什麼
spherical radiation
解釋
球輻射-
Figuratively, one may imagine the radiation of such a spherical maser as resembling a little hedgehog.
可以很形象地把這種球狀脈塞源的輻射想象為一個小刺蝟球的樣子。 -
Abstract : it is observed that the sommerfeld ' s formula for a progressive spherical wave is not covariant with respectro the rotation of the coordinate system. it contains complex partial waves that are not physical. the standing wave representation of the same formula is shown to be covariant and physical. it is applied to solve the boundary value problem of fiber optics. the radiation modes as well as the guided normal modes are obtained in closed forms. the intensity distribution in various modes is obtained. it is remarked that the mode of critical refraction is missing
文摘:說明了球面行波的索末菲公式在坐標轉動下不協變.證明了球面波的駐波表示是協變的，因而是一個物理的關系式，故適用於圓柱坐標中各類波動方程的定解問題.作為一個例，應用於光纖光學，導出了受導簡正模和輻射模的表達式，以及各模式的強度分佈 -
Besides, successfully calculating the electromagnetic four - potential in the spacetime of charged black hole expressed by the generali zed spherical coordinate and furtherly solving the h - j equation of such spacetime make it possible to get the exact description of the energy extent of nonthermal radiation particle and to study the characteristics of such black hole ' s nonthermal radiation
另外，本文還求出了一類用扁橢球坐標表示的荷電黑洞時空中的電磁四維勢矢量，從而成功地求解了此類彎曲時空中的hh方程，得到了這種非熱輻射粒子能量范圍的精確表達式，從而對這類黑洞的非熱輻射特徵進行了研究。 -
This paper deals with theoretical study on extinction characters of non - spherical particles and their smokescreen, which is one of the fundamental researches of smokescreen technology. the mathematical radiation extinction model of particles is discussed, and numerical simulation of extinction characters of particle and smokescreen is developed
