简介：我们在场在intracavity冷却并且外部洞为光制冷冷却之间的比较。结果证明intracavity计划在低光密度(0.01)被比较喜欢。我们能在实验为不同案例选择合适的计划。而且在一样的条件下面，拿做Yb3+的ZBLAN(ZrF4-BaF2-LaF3-AlF3-NaF)作为一个例子拍摄，二个计划的冷却过程被获得。计算结果证明冷却的intracavity将为一件薄电影样品完成更大的温度落下。最后，二极管激光可以为简短讨论的intracavity模型成为一个候选人。[从作者抽象]

简介：纸基于准确公平可靠，相对错误函数作为损失功能在被拿开发最佳的Bonus-Malus系统(BMS)的一个图案。在BMS，频率和严厉部件被考虑。这个图案与从古典方形错误的损失功能导出的传统的BMS相比。
