approximate vt. 1.使接近。 2.接近;走近。 3.近似,約計(jì)。 4.模擬。 5.估計(jì)。 approximate a solution to a problem 使問題近于解決。 approximate something to perfection 使某物臻于完善。 The total income this year approximates 10,000 dollors. 今年總收入接近一萬元。 approximate the motions of the stars in a planetarium 在天文館中模擬行星的運(yùn)行情況。 We approximated the distance at 100 miles. 我們估計(jì)行程距離為100英里。 vi. 近于。 His income this year approximates to 8,000 dollars. 他今年的收入接近八千美元。 adj. 近似的,大概的。 an approximate account 簡(jiǎn)要的說明。 an approximate date 大約的日期。 the approximate estimate 大概的估計(jì)。 an approximate number 概數(shù)。 an approximate value 近似值。 adv. -ly 大體,大致。
In chapter 2 there are four goals : the first is to investigate some geometric properties of h - caccioppoli sets , the second is to characterize the discontinuous set su and jump set ju of u bvh ( ) , the third is to study pointwise behavior of u bvh ( ) and our effort is concentrated on showing approximate differentiability of u in the sense of pansu ' s , while the last and the most important is to show that dhu with u bvh ( ) as a radon measure can be split into three parts ( absolutely continuous part , jump part and cantor part , respectively ) just like the derivative of a bv function in the setting of euclidean space 第二章有四個(gè)目標(biāo):一是討論h - caccioppoli集的若干幾何性質(zhì),二是刻畫h -有界變差函數(shù)的近似不連續(xù)點(diǎn)集和跳躍點(diǎn)集的特征,三是研究u bv _ h ( )的逐點(diǎn)行為,我們集中討論u在pansu意義下的近似可微性,最后也是最重要的目標(biāo)我們證明對(duì)u bv _ h ( ) , d _ hu作為radon測(cè)度能夠分解成絕對(duì)連續(xù)部分、跳躍部分和cantor部分之和。
