Hyper - voltage numeric calculation 過(guò)電壓及數(shù)值計(jì)算
Method to determine the type used to contain the result of a numeric calculation 方法確定用來(lái)包含數(shù)值計(jì)算的結(jié)果的類型。這取決于結(jié)果數(shù)字的存儲(chǔ)要求。
Through tests the paper studies the relationship between shear strength and water content of hefei expansive soil . a one - dimension numeric calculation model about the moisture variety in unsaturated expansive soil is built 實(shí)驗(yàn)研究了合肥膨脹土抗剪強(qiáng)度指標(biāo)c和與天然含水量之間的關(guān)系,并提出合肥膨脹土隨含水量變化的抗剪強(qiáng)度公式。
This is a novelty of the paper . in heat transfer there are problems in converting a mass of data , which is from numeric calculation and hardware collection , to visual image ; these problems have many relations with the applications of heat transfer relevant subject 這是本課題研究的一個(gè)新穎之處,在熱力傳導(dǎo)中,大量存在著將數(shù)值計(jì)算及硬件采樣所獲得的大量數(shù)據(jù)轉(zhuǎn)化為可視化圖像的問(wèn)題;這一問(wèn)題與傳熱學(xué)相關(guān)學(xué)科的可應(yīng)用于實(shí)際中有著密切的聯(lián)系。
As a result the prototype that was function satisfactory and user friendly , has developed with vb and matlab commercial software . because the numeric calculations are all done by anns , the software is able to transplanted and embedded in different blast furnaces and different software 利用數(shù)據(jù)庫(kù)中30組數(shù)據(jù)對(duì)系統(tǒng)進(jìn)行輸入以訓(xùn)練神經(jīng)網(wǎng)絡(luò),當(dāng)顯示訓(xùn)練完畢后,將數(shù)據(jù)庫(kù)中剩余的27組數(shù)據(jù)輸入以對(duì)神經(jīng)網(wǎng)絡(luò)對(duì)高爐鐵水硅含量預(yù)測(cè)結(jié)果的命中率進(jìn)行檢測(cè)。
On the basis of theoretic analysis and numeric calculation , the author verifies that only is the ratio of the fundamental period of the structure to the disturbance period beyond 1 . 4 , it ' s possible to achieve reductions in both the relative displacement and the absolute acceleration responses 作者在此基礎(chǔ)上,從理論分析和數(shù)值計(jì)算兩方面證明了粘性變阻尼控制僅在結(jié)構(gòu)周期與激勵(lì)主周期的比值大于1 4時(shí)才有可能同時(shí)減小結(jié)構(gòu)的位移反應(yīng)峰值和加速度反應(yīng)峰值。
We give a mathematical proof for the model - approximately independence of anc coefficient . combining a concrete nuclear reaction , we check up the model - approximately independence of anc coefficient with numeric calculation . under the el transition condition , a expressions with anc coefficient to compute the cross section of radiative capture reaction has been given in this thesis 我們對(duì)anc系數(shù)的近似模型無(wú)關(guān)性給出了一個(gè)數(shù)學(xué)形式理論證明,并結(jié)合具體的核反應(yīng),利用數(shù)值計(jì)算驗(yàn)證了anc系數(shù)的近似模型無(wú)關(guān)性;在e1躍遷情況下,我們給出了一個(gè)用anc系數(shù)計(jì)算輻射俘獲反應(yīng)截面的計(jì)算公式。
Because the model used in the paper is different from other methods of judgment to slagging , all the variables affecting slagging are assigned the local values resulted from numeric calculation ( in other methods , the parameter to affect slagging can only use one flag value ) . hence , the judgment to the slagging condition on any specific node of the grid can be made , so that effective and timely measures can be taken during operation 因?yàn)?,與其它結(jié)渣評(píng)判方法不同的是,本文的模型中,影響結(jié)渣的各變量全部用數(shù)值計(jì)算結(jié)果得到的當(dāng)?shù)刂?其它判斷方法所用的參數(shù),對(duì)一臺(tái)爐子只用一個(gè)標(biāo)志值) ,這樣給出的是受熱面上任一網(wǎng)格節(jié)點(diǎn)的結(jié)渣情況,以便運(yùn)行過(guò)程中及時(shí)有效地采取措施。
On one hand , the internal forces and displacement formulas of csbcs were deduced by using the matlab program , on the other hand , taking out of one wavelength of csbcs and soil from the actual project as the analysis object , simulation numeric calculation was carried out by using big - style fem ( finite element member ) software , ansys 一方面,用matlab編程,推導(dǎo)了波紋鋼板橋涵的內(nèi)力和位移公式,另一方面,取一個(gè)波紋長(zhǎng)度的波紋鋼板橋涵和土作為分析對(duì)象,用大型有限元軟件ansys對(duì)湖北洪沙線豐收渠橋涵工程的靜載試驗(yàn)進(jìn)行了模擬數(shù)值計(jì)算。
