中文拼音 [zìránchéngfǎ]
自然乘法
英文
natural multiplication-
Different algorithms were compared in the numerical simulation and model experiment of concrete velocity inversion the results showed that, compared with the least - square solutions and the damped least - square solutions, the damped and natural weighted least - square solutions reflected the inner defections of the tested object more reliably and exactly due to the usage of correct priori information, which benefited the suppression of noises and made the iterations of inverse stable and convergent
結果表明，相對于最小二乘法和阻尼最小二乘法，基於自然權的加權阻尼最小二乘演算法，由於利用了正確的先驗信息，不但使反演過程收斂，而且具有數值穩定、抗噪能力強的優點，其成像結果能真實有效地反映對象內部缺陷，因此更適用於混凝土的超聲波速度反演。Compared with straight ray tracing, inversion of bending ray tracing is better when data of test are accurate. on the other hand, natural weight is introduced and numerical simulations and experiments of wlm on inversion of velocity and attenuation are also made, which show that wlm, with resistance of noises and convergence of iteration, may get good re - construction images
本文引入了物理意義明確的自然權，對基於自然權的加權阻尼最小二乘反演演算法（ wlm ）在速度反演、衰減反演中進行了數值模擬和試驗研究，結果表明wlm均能獲得良好的重建圖像，迭代收斂，抗噪能力強。The main contents can be listed as follows : 1. after analyzing the properties of the natural illuminating system, a region - based background and natural illumination model is set up using the histogram of image difference and rls filter. on the basis of that model, we propose an adaptive algorithm of judging and updating background image
基於戶外自然光照系統的特點，建立了基於圖像差分直方圖和遞推最小二乘濾波（ recursiveleastsquarefilter ，簡稱rls濾波器）的局域化背景和光照變化模型，提出了自適應的背景判斷和更新演算法。It comes up with a new notion, d - solution, which is applied to the distance estimation, by virtue of hilbert space ; furthermore, the dissertation has gained a necessary condition which is identity of minimum mean - square value in linear function classes, so that d - solution extends minimum mean - square value within the domain of nonlinear function equation or equation system ; and, the dissertation studies in detail the classical moment estimation and maximal likelihood estimation on the parameters of ar ( p ), a series of theorems in the estimation section shows the moment estimators are consistent on the ground of large samples jikewise, those distribution functions of the estimated parameters accord to maximum likelihood estimation converge gauss distribution if the white noise is gaussan
首先，藉助hilbert空間理論，提出了距離估計的d -解，給出了d -解的必要條件，這個條件在線性函數類里即是極小二乘估計法， d -解的必要條件滿足的方程實質上將極小二乘估計法推廣到多函數及非線性函數類。再而，詳細地研究了多元弱平穩序列自回歸模型ar （ p ）的參數經典的矩的替代估計和極大似然估計，獲得矩的替代估計的一致性的結果。對基於gauss白噪聲假設多元弱平穩序列自回歸模型的均值、白噪聲的協方差陣的極大似然估計都有依分佈收斂到多元正態分佈的統計性質。Because of his compassion and his aspiration to carry on with his dharma activities to liberate all sentient beings, the karmapa has returned to our fold of his own free will. with the power of such blessing, all dharma activities of this nature will naturally come to fruition
因為大寶法王的悲心與佛行事業，度眾事業，使他乘願再來，以此加持力，任何這類的佛行事業自然任運而成，不須要我們來擔心的。He said to himself, " two plus five, the son of a bitch is seven. three plus six, the son of a bitch is nine.
他自言自語道： 「二乘以五，他媽個雞是十。三乘以六，他媽個雞是十八。 」加法竟然被翻譯成乘法，這是意譯嗎？分享友人
