In order to keep variations negligibly small, only small perturbations will be considered . 為了使變分小到可以忽略的程度,僅考慮微小的擾動。
The series solution for boundary value problem of nonhomogeneous harmonic equation with variable coefficient is obtained 使變系數(shù)非齊次調(diào)和方程邊值問題的求解有了新的進展。
I squint through sweat - filled eyes at the display . ken ' s voice echoes in my ear . for the first time , i hear desperation 我在展覽使變斜視眼過汗裝滿的眼睛??隙鞯穆曇粼谖业亩渲须S聲附和。第一次,我聽到沮喪。
From customer relationship management and analysis tools , to corporate resource systems , the sheer size of online applications is growing fast 無論是客戶關(guān)系管理和分析工具還是公司資源系統(tǒng),都可以使變小后的在線應(yīng)用程序快速運行。
To each of liquid and solid , the most of way is perpendicular installation , make the medium from lower to upper , it will be made attrition uniform in the transmitter , prolong using life - span 對于液固兩相流體,最好采用垂直安裝,使被測介質(zhì)自下而上流動,可使變送器襯里磨損均勻,延長使用壽命
Consequently , this scheme is feasible and valid . the research enriches the contents of variational assimilation and makes it more extensive application , which increases the quality of initial fields in nwp 因此,將遺傳算法應(yīng)用于四維變分資料同化是切實可行而且有效的,這一工作豐富了變分同化的內(nèi)容,使變分同化技術(shù)作為提高數(shù)值預(yù)報初始場的質(zhì)量這一有效技術(shù)得到了進一步的應(yīng)用。
And going on in this chapter the prophet isaiah says , i will lead the blind by ways they have not known , along unfamiliar paths i will guide them . i will turn the darkness into light before them and make the rough places smooth . these are the things i will do 先知以賽亞繼續(xù)說:我要引瞎子行不認識的道,領(lǐng)他們走不知道的路,在他們面前使黑暗變?yōu)楣饷鳎?font color="#cc0033">使變曲變?yōu)槠街?,這些事我都要行,并不離棄他們。
A novel dna modification discovered in streptomyces lividans is different from dna methylation . this unusual modification causes wild type s . lividans dna sensitive to site - specific oxidative double - strand cleavage ( dnd phenotype , dna degradation ) 變鉛青鏈霉菌的dna異常修飾系統(tǒng)是一種不同于甲基化修飾的新型修飾系統(tǒng),它可使變鉛青鏈霉菌dna在電泳時易遭到氧化雙鏈切割( dnd表型, dnadegradation ) ( zhouetal . , 1988 ) 。
In this thesis , the decoupling unit of vav system is designed in the way of feedforward conpensation . then the transfer function matrix of the feedforward conpensation decoupling unit of the 5 inputs & 5 outputs vav system is worked out . the decoupling conpensation unit can change the transfer function matrix of the open loop and closed loop control system into diagonal matrix , so that the coupling among the five control loops is eliminated , and vav system is decoupled 本文采用前饋補償法設(shè)計了變風(fēng)量空調(diào)系統(tǒng)的解耦補償器,并得出了五輸入、五輸出變風(fēng)量空調(diào)系統(tǒng)前饋補償解耦器的傳遞函數(shù)矩陣,該解耦補償器可以使本文所研究的變風(fēng)量空調(diào)控制系統(tǒng)的開環(huán)傳遞函數(shù)矩陣和閉環(huán)傳遞函數(shù)矩陣都變換為對角矩陣,從而解除五個控制回路之間的耦合,使變風(fēng)量空調(diào)系統(tǒng)實現(xiàn)解耦。
