Examples

Using the beam propagation method ( bpm ) simulation , we confirm that wide controllability of the branching ratio and low excess loss can be realized by this structure
用bpm方法模擬的結果表明，此結構實現(xiàn)了50 - 94的不對稱分支比，并且具有低的附加損耗的特點。
Site - select spectra indicate that the eu3 + in nanoparcles < wp = 7 > formed two kinds of luminescence centers with different branch ratios of 5d0 - 7fj . the ratio of varied with different excitation
用不同能量激發(fā)zns時5d0 7f0與5d0 7f1發(fā)光分支比不同，表明激發(fā)能量對兩類發(fā)光中心的激發(fā)具有選擇性。
Some microscopic theoretical analysis indicates the branching ratio of the transitions near zero degree is not sensitive to the halo structure . the complete angular distribution of the " h ( 6he , 6li ) n reaction has to be measured to reveal the halo structure of the second exited state of 6li
有的微觀理論分析表明， 0附近的該躍遷強度比對是否存在暈結構不敏感，要想揭示~ 6li第二激發(fā)態(tài)的暈結構，應該測量~ 1h ( ~ 6he ， ~ 6li ) n反應完整的角分布。
The author has calculated the spontaneous radiate probabilities , the linear oscillator strengths , branching ratio of tm3 + iones by judd - oflet theory . according to the j - o calculated data , the transition 1g4 ? 3h6 was stronger than the transition 1g4 ? 3h4 . it was agreement with the emission spectra
3 ）對tbzre玻璃，用j ? o理論計算了各光譜參數(shù)，從1g4能級的躍遷分支比從理論上得出480nm波長的光相對650nm波長的光強，這與發(fā)射光譜圖是相符合的。
A wide range of the branching ratio can also be achieved for the asymmetric case . using supermode theory , i compared the design results of directional coupler by means of 2d mode and 3d mode and designed 3db directional coupler using 3d bpm and couple mode theory
實際的設計過程中，考慮到定向耦合器輸入波導和輸出波導部分的耦合影響，圍繞耦合模理論計算結果手動調(diào)節(jié)耦合區(qū)長度，并應用三維bpm來模擬設計，得到耦合區(qū)長度，設計了精確的3db定向耦合器。
5 . the luminescence enhancement of eu3 + was also observed after ultraviolet irradiation but was weaker than the zns : mn2 + and the branch ratio of 5d0 - 7f0 increased after irradiation . it indicates probably the contribution from the centers in the surface of nanoparticles increased
在紫外光的輻照下首次觀察到eu3 +離子發(fā)光的熒光增強現(xiàn)象，輻照后5d0 < wp = 5 > 7f0發(fā)射強度分支比增加，表明對稱性較低的發(fā)光中心對發(fā)光的貢獻增加，可能是處于顆粒表面的eu3 +離子對發(fā)光的貢獻增加。
