简介：Farr-Gao算法是为减少的Gr的一个最先进的算法?bner有限的点的消失的理想基于，它作为一个内建的命令在枫树被实现了。这份报纸为它论述二维的改进那为计算减少的Gr采用预处理策略?与给定的点集合的塔子集联系的bner底。试验性的结果证明preprocessedFarr-Gao算法比古典的更有效。

简介：分离mKdv方程的一个准确two-soliton答案被使用Hirota直接途径导出。另外，我们阴谋soliton答案讨论solitons的性质。注意我们获得在二solitons之间的完全有弹性的相互作用，是值得的。

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]
