partial equation中文什么意思
例句與用法
- only clouds of points instead of grids are distributed over the computational domain and the spatial derivatives of the considered partial equations are estimated using a least-square curve fit on local clouds of points
與傳統(tǒng)的網(wǎng)格方法不同，無網(wǎng)格方法的核心是用“點(diǎn)云”離散求解區(qū)域，并基于當(dāng)?shù)攸c(diǎn)云離散結(jié)構(gòu)，引入二次極小曲面逼近空間導(dǎo)數(shù)。 - t-s model is a novel fuzzy reasoning model which replaces the parameters of traditional reasoning system with linear partial equation . therefore, it can generate complicated nonlinear equation with fewer fuzzy rules . but the conclusional parameter is not a fuzzy rule but a linear equation, it can not be got from expert's experience and operational data directly . we must refine the parameter with some algorithm . by constructing t-s fuzzy neural networks we can solve the problem easily
t-s模型是一種新穎的模糊推理模型，它以線性局域方程取代了一般推理過程中的常數(shù)，因此可以用少量的模糊規(guī)則生成較復(fù)雜的非線性函數(shù)。但是由于結(jié)論參數(shù)是線性函數(shù)而非模糊數(shù)，所以規(guī)則不能直接從專家經(jīng)驗(yàn)和操作數(shù)據(jù)中直接得到，必須通過一定的算法進(jìn)行提煉。因此模型參數(shù)的辨識(shí)成為建立t-s型模糊系統(tǒng)的主要問題。 - it is wekk known that the fractional integrals, the commutators for the macinkiewicz integrals and the multilinear operators play a profound and extensive role in harmonic analysis and the partial equations . in this thesis, we'll discuss the mapping properties of these kinds of operators . our thesis consists of five chapters . chapterl is the introductions
由于分?jǐn)?shù)次積分算子，marcinkiewicz算子的交換子，多線性算子是調(diào)和分析的重要算子，他們不僅在調(diào)和分析中有著重要的地位，而且在偏微分方程具有著及其重要的作用。本文致力于這些算子的研究。 - nonlinear analysis is an important branch of modern analysis . it has been become a much more important tools for dealing with the nonlinear problems arising in many applied mathematics . it is also an important method for studying the nonlinear integral equations, the differential equations and partial equations
非線性泛函分析是現(xiàn)代分析數(shù)學(xué)的一個(gè)重要分支，是處理許多非線性問題的重要而有力的工具，在處理應(yīng)用學(xué)科提出的各種非線性積、微分方程和偏微分方程中發(fā)揮著不可替代的作用 - in chapter 2, the ii ordering is presented and the arbitrary functions and the arbitrary constants are least in the solution of formal series under the ii ordering by illustration; furthermore, the author introduces the application of the standard form of reid to ascertain the target equation of linear constant partial equations
在第二章中，作者給出了reid標(biāo)準(zhǔn)型算法中的型序關(guān)系，通過舉例說明在型序下，得到的形式冪級數(shù)解中任意函數(shù)和任意常數(shù)的個(gè)數(shù)最少；并提出了reid標(biāo)準(zhǔn)型的一個(gè)重要應(yīng)用：確定線性常系數(shù)偏微分方程組的目標(biāo)方程。
