    但是，苔絲至少在她從搖籃時(shí)代就開(kāi)始呀呀學(xué)唱的古老的萬(wàn)物頌中，找到大約可以表達(dá)她的感情的句子因此這也就足夠了。
  • In order to ascertain stress concentration factor of a member , the approximate expression of strain can be established in the region of stress concentration by using the elastic theory providing the member is predigested suitably
    摘要為確定構(gòu)件應(yīng)力集中處的應(yīng)力集中系數(shù)，通過(guò)對(duì)構(gòu)件簡(jiǎn)化后進(jìn)行彈性分析，建立應(yīng)力集中處的近似應(yīng)變表達(dá)式。
  • By combining the linearization of the rewritten governing equation with the method of harmonic balance , improved analytical approximate expressions of the frequency and the corresponding periodic solutions of the oscillator are derived
    通過(guò)將變形后的控制方程的線性化與諧波平衡法組合起來(lái)，我們建立了達(dá)芬諧波振子頻率及周期解的改進(jìn)解板逼近。

    同時(shí)將本文建立的方程與現(xiàn)有的幾種計(jì)算橫向各向同性介質(zhì)中反射、透射系數(shù)的近似公式進(jìn)行了比較，對(duì)不同的理論模型和不同的地層條件進(jìn)行了多波ava正演。
  • From the exact expression of the field , we obtain a multipole polynomial expansion , and under the paraxial condition we furthermore obtain the approximate expression . the loffe trap , consisting of two coils with parallel currents and four straight conductors with currents in alternating directions , is one of the most important traps . we specially study the field structure of it by using both the exact expression and a multipole polynomial expansion that facilitates studies of classical or quantum orbits . if the region near the origin is of interest , we may obtain a simple expression of the field and this configuration may be called idealized loffe trap
    若只討論阱中的近原點(diǎn)區(qū)域時(shí)，阱中的磁場(chǎng)可以呈現(xiàn)出一種簡(jiǎn)潔的形式，人們把它稱為理想ioffe阱。磁矩反平行于磁場(chǎng)的中性粒子在阱中與磁場(chǎng)發(fā)生相互作用，借助相互作用勢(shì)，可以獲得粒子在阱中的經(jīng)典運(yùn)動(dòng)方程。在一定的近似條件下，我們可以采用逐次近似的方法，使方程簡(jiǎn)化，其中三個(gè)分量式中關(guān)于z的方程比較容易求解，而關(guān)于x 、 y的方程則演化為我們熟悉的馬丟方程的形式。
