揭示出在高掺Yb3+的石英基光纤中，共掺Al3+的摩尔浓度为Yb3+摩尔浓度的9—11倍时既可以减小Yb3+的浓度猝灭概率，又可以获得高吸收系数，同时还可更好地满足数值孔径的要求的结论。

A novel Er3+-doped tellurite glass with compositions of TeO2-ZnO-Na2O-Bi2O3 was prepared, and the intensity parameters, spontaneous emission probability, absorption and emission cross-section of Er3+ ions were calculated according to the Judd-Ofelt and McCumber theory.

研制了一种新型掺铒碲酸盐玻璃TeO2-ZnO-Na2O-Bi2O3，利用Judd-Ofelt和McCumber理论计算了Er3+离子的强度参数、自发辐射几率、吸收截面和发射截面等光谱参数。

Therefore, the energy of π(superscript *) orbit decreases, the probability of optical absorption increases, the n→π(superscript *) electronic transition enhances, and the absorption band broadens and shows red-shift. The above phenomenon will result in the degradation of optical properties of ZnO/silicone white paint under proton exposure.

同时Si-O-Si链内氧原子未成键的孤对电子与邻近硅原子的3d空轨道配位，降低了π轨道的能量，提高了对光吸收的几率，增强了n→π电子跃迁，使吸收带红移，从而导致ZnO/silicone白漆光学性能退化。

On the other extreme, when all of a teenager's peers are sexually abstinent and worship weekly, the probability of that teenager being sexually active is 3 percent.

在另一极端，当所有少年的同辈是性abstinent 和崇拜周刊，那个少年的可能性是性活跃的是百分之3 。

Central bank's monetary policy report has been no "tightening" the wording, but in negative interest rates, inter-bank market funds are more abundant, a large number of outflow of hot money is not an environment immediately lowered the deposit reserve ratio of the probability of very small.

央行的货币政策报告已没有"紧缩"的措辞，但在负利率，银行间市场资金较为充裕，有热钱大量流出的环境不立即降低了存款准备金率的可能性非常小的。

Adjusting the probability of acceptance could control the speed of chaos simulated annealing, and influence the rate of convergence.

接收概率衰减速度的调节可以控制混沌退火的速度，从而影响网络的收敛速度。

So the probability of call acceptance will be improved.

CRSVP模型与Intserv/RSVP的区别主要在二个方面。
