variance law造句
例句與造句
- According to the fluctuating property of wind , on the stochastic vibration finite element theory , some calculation formulas of the response , including the along - wind response and the across - wind response , are obtained , the ideology of the torsion vibration in the double - tower structure and the ideology of the double - tower structure ' s dynamical wind load are also put forward at the same time . by using the stochastic vibration module of the general finite element program , the paper analyses the performance of the wind resistance more deeply and fully , discussing the influence on the double - tower structure from the diversification of the different component . the variance law of dynamic displacement and wind - induced vibration coefficient is derived through analyzing structure stochastic vibration , so is the effect of several parameters on dynamic displacement , acceleration and wind - induced vibration coefficient
從結(jié)構(gòu)風(fēng)振的基本理論出發(fā)，通過對脈動風(fēng)功率譜的分析，推導(dǎo)了結(jié)構(gòu)風(fēng)振響應(yīng)(順、橫風(fēng)向)的計(jì)算公式，同時提出了雙塔結(jié)構(gòu)的扭轉(zhuǎn)振動和動力風(fēng)荷載計(jì)算的思想，在結(jié)合通用有限元程序的隨機(jī)振動模塊的情況下，對雙塔結(jié)構(gòu)的抗風(fēng)性能作了深入、全面研究，探討了雙塔結(jié)構(gòu)構(gòu)件截面的變化對其抗風(fēng)性能的影響，同時探討了順風(fēng)向風(fēng)速譜的選取、風(fēng)速、參與計(jì)算的振型數(shù)、風(fēng)與結(jié)構(gòu)耦合作用是否考慮等因素對分析結(jié)果的影響，比較了規(guī)范風(fēng)振系數(shù)的計(jì)算與隨機(jī)算法結(jié)構(gòu)的異同，并討論了原因，得出一些有意義的結(jié)論。 - It's difficult to find variance law in a sentence. 用variance law造句挺難的
