cross sectional

基本解釋

The cross sectional transitions are smooth to avoid dead spaces and minimize pressure loss.
橫截面的平滑轉(zhuǎn)變避免了死空間，并且使壓力損失達(dá)到最小。
Where ρ is the density of air, A is the cross sectional area, and C is the drag coefficient for a cylinder.
上述表達(dá)式中，p表示空氣密度，A代表圓柱的橫截面面積，C代表圓柱的牽引力（阻力）系數(shù)。
The ratio of aircraft length to maximum cross sectional area also influences the intensity of the sonic boom.
飛機(jī)的長度和最大橫截面面積之比也會(huì)影響音爆的強(qiáng)度。

The piston has a cross-sectional area, a, and the force pressure is force per volume area.
我們以活塞系統(tǒng)為例，來說明膨脹功。

It's a more powerful method than something called a cross-sectional study, and I'll come back in a later lecture and talk about these in more detail, but a cross-sectional study means you're taking a snapshot of a population of people at one time.
這種方法比所謂的橫斷面研究更加有效,我將在以后的課中,再仔細(xì)討論這個(gè)問題,但橫斷面研究是指,你一次記錄下一群人的狀況

Well, a cross-sectional study would mean that you'd get a random group of the population and measure them in 1970 and then take another random group five years later and measure them, but it wouldn't be the same people necessarily, it would be different groups of people.
那么,橫斷面研究就是,1970年你在人群中隨意選擇一組人,并記錄下相關(guān)數(shù)據(jù),然后,五年后再隨意選擇一組人記錄數(shù)據(jù),但這不需要是同一組人,通常是不同的人
