简介：我们为f(T)严肃理论在宇宙论的限制的精确上探索SandageLoeb(SL)测试的影响。因为它在远类星体的系列在Lyman-森林里测量redshift飘移，SL测试是对当前的宇宙论的观察的重要补充，盖住2z的redshift沙漠5。避免数据矛盾，当模仿30的基准的模型嘲笑SL测试数据，我们基于当前的联合观察数据使用最好合适的模型。我们确定为f(T)严肃理论的参数评价上的这些SL测试数据的影响。二个典型f(T)模型被考虑，幂定律模型f(T)PL和指数形式的模型f(T)终止。结果证明SL测试罐头有效地打破存在在在另外的宇宙论的观察的今日的事密度m和小瘤常数H0之间的强壮的退化。为考虑f(T)模型，SL测试的30年的观察能极其改进m和H0的限制精确，但是不能有效地改进模型参数的限制精确。

简介：水泡的行为上的可视化研究为水池在压力0.1MPa在一个水平透明加热器上沸腾R141b被执行了。水泡的行为被在加热器表面下面放的一个高速度的照相机记录。离开直径，水泡的离开时间和在不同的热流动的成核地点密度被获得。可视化结果证明水泡离开直径和离开时间减少，当当热流动增加，成核地点密度增加时。没有液体，在实验招募进microlayer，这也被观察。基于试验性的结果，煮曲线因为R141b被使用动态microlayer模型预言。作为结果，在基于动态microlayer，为沸腾的模型和实验数据R141b弄弯的预兆的结果之间的协议擅长高热流动。关键词R141b-热转移-水泡动力学-水池沸腾CLC数字TK124
