邊際變異 的英文怎麼說
中文拼音 [biānjìbiànyì]
邊際變異
英文
marginal variation-
So for, because of the restriction of experiment boundary condition that different original condition and over ideal theorization model that is mentioned in the preface, it is imminence needs to understand the changing of reality soil on the true wave loading in true time and space so that validated and lead next research in theory and simulation
正如在前言中對此方面研究評述所提及，目前的研究被與實際迥異的實驗邊界條件和過分理想化理論模型制約，迫切需要了解真實的時間和空間尺度下，真實的土體在真實的波浪荷載作用下將發生怎樣的變化，以驗證和引導我們進行的理論與模擬研究。It is shown by structural seismic response of four wavelets that littlewood - paley wavelet is not suitable for structural seismic response, because structural response is too small, meyer wavelet is a better wavelet for structural seismic response, for it ' s structural response is agreement with the finite element method, and also harmonic wavelet, structural response under earthquake is a little bigger than finite element method, structural response under odd exponent wavelet is also bigger than finite element method, this method is very simple by wavelet transform, wavelet transform method is different from old methods, one is with which not only knows the effects of earthquake wave detail frequency - band on structural response, but also considers earthquake wave ' s non - stationary of frequency and time - domain value, another is the second mode shape and higher mode shape response that do n ' t attenuate so fast
通過對這四種小波的結構地震反應分析研究說明： littlewood ? paley小波不適合於用來作結構地震反應分析，因為在littlewood ? paley小波下的結構地震反應太小，不符合實際情況；用meyer小波作結構地震反應分析比較合適，和有限元法的結果比較接近；也可以用諧波小波來作結構地震反應分析，只是在諧波小波下的結果略為偏大；單邊指數小波下的結構地震反應分析比有限元法稍大一點，它通過小波變換大大簡化了結構地震反應分析。用小波變換方法來進行結構地震反應分析和以往方法不同的是：它不僅可以知道地震波的具體頻率段對結構反應的影響，而且同時考慮了地震波的幅值非平穩性以及頻率非平穩性；另外與以前方法得到的結果有差異的是，第二振型及以後的高一點的振型的反應沒有以前的方法衰減得快。The paper deduce the need of labors in cities in a region and further deduce the really scale of labors in these cities. as a result, this paper proves that the gaps of the level of urbanization will change and disperse ultimately when the marginal output of labor and the labor capital ratio are different and constant
從而推導出區域城市部門對勞動力的需求，進而推導出這些城市的實際勞動力規模，並證明：在勞動邊際產出、勞動?資本比例不同，且一定的條件下，兩個區域的城市化水平差異是變動的。At last, the welfare loss when oligarchic business ' s marginal cost and demand and product differentiate vary is researched, the policy advice is given to the government how to regulate
最後，研究了各種寡頭模型企業在邊際成本變化，需求變化，產品差異度變化時福利的損失情況，並對政府如何進行調節和控制提出政策建議。分享友人
