One of the most important innovations in his analysis was the application of the theory of probability to account for the statistical variation of the agitating forces on bed particles caused by turbulence 在他的分析中其中一個(gè)最重要的革新,是應(yīng)用在紊動(dòng)流場(chǎng)的攪動(dòng)力作用于河床粒子時(shí)去計(jì)算統(tǒng)計(jì)上變量的概率理論。
One of the most important innovations in his analysis was the application of the theory of probability to account for the statistical variation of the agitating forces on bed particles caused by turbulence 他著作中的重要革新是使用了概率論,當(dāng)流沙床面在受到力的作用時(shí),用這個(gè)概率論來(lái)計(jì)算床面顆粒攪動(dòng)力的統(tǒng)計(jì)變化。
