南京航空航天大学学报 法模拟了气囊充气过程,获得了充气过程中,气囊外形和流场之间的动态关系,分析了囊内流场的动态变化情况,并和气囊分析的控制体积(control volume,cv)法进行了对比。结果表明,cv方法尽管简单,但对于高速下的气囊充气过程.无法获得囊内瞬态的流场变化及气

此外,控制系统的体积更小,这样整个装置到能方便地运送到其它实验室。
In addition, the control system has been reduced in size, so the entire apparatus can be transported easily to other laboratories.
一些人类学家注意到大脑体积减小其实并不令人惊讶,在我们变得更强更大之后,我们需要更多的灰质来控制躯体这个大麻烦。
Some anthropologists note that brain shrinkage is not very surprising since the stronger and larger we are, the more grey matter we need to control this larger mass.
大体积混凝土的温度应力问题与温度控制要求在碾压混凝土坝中同样存在。
The problem of thermal stress and a need for temperature control in the mass concrete construction also occur in the roller compacted concrete dams(RCCD).
That is, in real life, the variables that you'd normally control aren't some combination of entropy and these variables, but really their temperature, volume and pressure, any couple of those, might be what you'd really have under experimental control.
在生活中,我们所能控制的,不是熵和其他变量的组合,而是温度,体积,压强,以及其中的两两组合,这些才是试验中所能控制的。
