orthogonal expansion造句
例句與造句
- Are uncertain and should be regarded as random variables , therefore the reinforced concrete frame is stochastic structure inherently , and then its motive equations converted to combined random differential equations for the uncertain parameters and external random excitation . these equations were solved by order - orthogonal expansion method with pseudo - excitation method , and then the statistic stochastic responses of random structure were obtained . at last , based on the stochastic cumulative damage model with double parameters developed by park , formulas were formulated for calculating structural earthquake damage probability using the structural reliability theory ( mainly jc algorithm ) in extensive random space
首先對(duì)受地震激勵(lì)的剪切型鋼筋混凝土結(jié)構(gòu)進(jìn)行建模，用隨機(jī)等效線性化方法將二階非線性微分方程組化成一階線性微分方程組(或稱之為狀態(tài)方程) ；再考慮材料等參數(shù)的隨機(jī)性，則狀態(tài)方程成為復(fù)合隨機(jī)微分方程組，將擴(kuò)階系統(tǒng)方法和虛擬激勵(lì)方法推廣并應(yīng)用于這個(gè)復(fù)合隨機(jī)微分方程組，求出結(jié)構(gòu)的隨機(jī)響應(yīng)量的統(tǒng)計(jì)參數(shù)；最后采用隨機(jī)累積損傷破壞準(zhǔn)則，在廣義隨機(jī)空間內(nèi)，用jc算法求解失效概率，進(jìn)而求出結(jié)構(gòu)的抗震可靠度。 - We have the following results . part i the computations of the bergman kernel functions the bergman kernel function plays an important role in several complex variables . s . bergman introduced the concept of bergman kernel function in 1921 when he studied the orthogonal expansion on d in c and he generalized it to the case in several complex variables in 1933
Bergman核函數(shù)的顯式表達(dá)bergman核函數(shù)在(單、多)復(fù)變函數(shù)理論的發(fā)展過程中起著十分重要的作用， bergman在1921年研究復(fù)平面中區(qū)域d上的正交展開，其研究結(jié)果導(dǎo)出了一個(gè)核函數(shù)k _ d ( z ， ) ， ( z ， t ) d d 。 - In this paper , based on an improved orthogonal expansion in an clement , using the new idea of ref .
