分子动能

温度是分子动能能量级，发育起点温度是启动生化反应的能量级，用活动积温表述昆虫发育所需热能比用有效积温更为确切。

As temperature is a molecular kinetic energy level , and the start temperature of development is an energy level to activate biochemical reaction , so using the active accumulated temperature to describe the energy needed for insect development is more accurate than using effective accumulated temperature .

用这个模型，我们分析了从Cu（111）铜单晶表面脱附分子的动能分布和角分布。

Using the model , we have investigated the kinetic energy and angular distributions of nitrogen molecules desorbing from the copper single crystal surface Cu ( 111 ) .

温度其实就是（分子）动能的体现。

Temperature is just kinetic energy .

以这种方式损失的能量最终表现为分子的动能或热能。

在物理学中，温度是组成一个物体的分子无序动能的一种量度。

In physics , the temperature is a measure of the disordered kinetic energy of the molecules constituting a body .

对于平衡条件下的汽液界面，由于汽液相变的影响，在紧贴界面处存在一个分子平均动能非平衡分布的区域。

The thermal non-equilibrium distribution through the interface region is caused by the energy transport between the liquid and the vapor phase .

理想气体的压力与分子的动能成正比，它的下限为零。

The pressure in a perfect gas , being directly proportional to the kinetic energy of the molecules , has a lower bound of zero .

升高温度可增加分子的平均动能，加快醇酸酯化、醛醇缩合、醛醛缩合等反应的速度。

Temperature rise could increase molecular average kinetic energy and quicken alcohol acid esterification , aldol reaction and aldehyde-aldehyde condensation .

分子（及其动能和动量）在邻近的流体层边界或细胞膜之间交换的过程。

An exchange of molecules ( and their kinetic energy and momentum ) across the boundary between adjacent layers of a fluid or across cell membranes .

C60分子以30eV初始动能入射到石墨表面时，将保持完好球形沉积在石墨表面；

At the impact energy of 30 eV , C_ ( 60 ) will deposit on the surface of the graphite and keep the sphere-like shape .

在太空中，一个个分子都有着很高的分子平均动能，只是它们数量太少影响不到你。

In space , individual molecules have a high average kinetic energy , but there are so few of them that they don 't affect you .
