简介:在那里存在,这被证明了在垂直的热之间的生气联合由使用线性热力学的狂暴的运输和垂直速度。这结果断言热的垂直部件狂暴的运输流动由垂直潜在的温度梯度的运输和垂直速度的联合运输组成。在这篇论文,垂直的热上的垂直速度的联合效果狂暴的交通被从大气的边界层使用观察数据决定联合系数的十字验证,并且狂暴的交通的一系列重要性质外面被打开。这些性质显示生气联合系数是尺寸的对数功能不太垂直的速度和尺寸更少高度,并且不仅与磨擦速度u*,有关而且到联合粗糙高度zW0和联合温度T垂直速度的W0。另外,仅仅当垂直速度大小遵循限制|W/u*时,功能关系建议那|≠1,并且在水平z然后,垂直速度导致生气联合的W0,垂直的热上的效果狂暴的运输流动。生气联合理论和试验性的结果提供挑战给传统的狂暴的K闭合理论和Monin-Obukhov类似理论。
简介:写陈冲的人实在太多了,多得让你无从下笔。或是在写“小花”,或是在写“大班”总之陈冲一向很难再是陈冲。她一路影星着、走红着、启承转合着她自己的故事和生活,外人便只剩下热闹地尾随和矜持着评判的份儿。陈冲像是那种更在乎自我判断超过他人作价的女人。十四五岁演“小花”获“百花奖”时,她就表现出那么一种很天然、很确定的自我意识,报纸上说她已“冉冉升起”,她就回报说在学校还是往常一样地上课、考试和睡觉,同学最大的反应是吃惊她“也会演电影”。在美国上学、打工、结婚、离婚、再结婚。这期间她一步步走进好莱坞,拍了各种各样的片子,尝试了各式各样的人物。成与败的每一件事都颇有声色。而这一次见到陈冲时,她已有了一个可爱之极的女儿和一桩桩做导演的成功业绩。银幕下的陈冲很自我:不化妆、不打理一头鸦雀都可以作窝的短发,不在身上的任何一处下真功夫点缀、短短的几十天里见过她四五面,竟有三次是同一件浅咖啡色的针织衫套在她原本大可招摇过市的性感身段上。问她时她会比你还惊讶地连连问“是吗是吗……我怎么没感觉呢”然后就很有感觉地破口大笑。笑声里底气很足,动静很大,频律上全无节制。再后来一听见笑声,就知那是陈冲优越、富足、健康、外加美国生活了近二十年的圆...
