駐波強度 的英文怎麼說
中文拼音 [zhùbōqiángdù]
駐波強度
英文
intensity of standing wave-
If the velocity of atoms is near to zero, the light for ces will tend to confine the atoms near to nodes and antinodes. the stability depends on the magnitude of the negative slope of the light force, the depth of the potential well and the momentum diffusion coefficient. it is important to select the parameters, e. g
如果通過激光冷卻能使原子速度降至很小甚至為零，光壓力的作用將使原子被較穩定地囚禁于激光駐波場的節點和反節點處，其穩定程度取決于該處光壓力曲線負斜率的大小、對應勢能的勢阱深度以及動量擴散系數的大小，因此，如何在實驗中合理選擇激光強度、失諧量等顯得尤為關鍵。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In the storm, the part on surface layer of the underlying bed will produce the liquefaction, the absolute standing wave that form the front of the structure may bring 6. 16 meter depth of the liquefaction, so the foundation of structure will lose part of the supporting force, the structure will slide in this situation. that is to say, because of the foundation partly liquefaction, the exist of soft layer and the component force of gravity, the structure slide further to the basin and collapse, which leads to disastrous consequence
在強暴風浪下，底床表層1 . 75米以上均有可能產生液化現象，而在構築物前形成的完全駐波，甚至能夠造成6 . 16米的液化深度，構築物地基部分失去支持力，將直接導致構築物的滑動，也就是說，在地基部分液化、軟弱層的存在以及構築物沿坡重力分力的共同影響下，構築物將向「盆」底方向發生更大的滑動，甚至可能發生倒塌。
