In part one , we dissuss the galerkin method and error estimate for first - kind boundary integeral equation derived by forrowing exterior dirichlet problems then result in superconvergent results by least - squares processing 首先,第一部分討論了由dirichlet外問(wèn)題:導(dǎo)出的一型邊界積分方程的解法及其誤差,然后進(jìn)行最小二乘處理后得到超收斂結(jié)果。
By integeral design of the senser and the circuits , the products has advantages of minisize , light weight , wide responding range , high sensitivity , etc . the results of performance test and environment examination indicate that , the design is reasonable , the arts rational , all performances arrive or exceed the demands of the contract . the product has passed the appraise rate of minister , arrived the international leading level 該傳感器具有微型化、重量輕、頻響寬、靈敏度高、傳感器與調(diào)理電路一體化的特點(diǎn)。經(jīng)性能測(cè)試和環(huán)境試驗(yàn)表明:該傳感器設(shè)計(jì)合理、工藝可行,各項(xiàng)性能指標(biāo)均達(dá)到或超過(guò)合同規(guī)定的要求,通過(guò)部級(jí)鑒定,達(dá)到國(guó)際先進(jìn)水平。
There are many papers ( cf [ l ] - [ 3 ] ) have studied the method and error estimate for boundary integeral equation and elliptic boundary value problems , and obtain some superconvergent results by varied post - processings such as interpolation , average and extrapolation etc . in this paper , we mainly study the galerkin solution for first - kind boundary integeral equation and elliptic boundary value preblem . further more we can obtain superconvergence results by ( l _ ( 2 ) project ion ) least - squares processing for derivative of elliptic boundary value problems 對(duì)于邊界積分方程與橢圓邊值問(wèn)題的解法及誤差估計(jì)已有很多文章(參[ 1 ] - [ 3 ] )研究,并且通過(guò)各種后處理如插值、平均、外推等得到一系列的超收斂結(jié)果,本文則著重探討一型邊界積分方程galerkin解通過(guò)l ~ 2投影(最小二乘)算子處理后以及橢圓邊值問(wèn)題的導(dǎo)數(shù)進(jìn)行l(wèi) ~ 2投影(最小二乘法)處理后可獲得超收斂結(jié)果。
When calculating it , the foundation effectness is taken in the controlling differential equation of thick - plate on the elastic foundation , general first the base solveness of the equation is derived by flouier integeral and 8 - function . , then the boundary integeral equation is created by image work theory , finally discret the boundary and the algebraic equation iscreated 在計(jì)算彈性地基板時(shí)把地基效應(yīng)歸并到彈性地基上中厚板彎曲問(wèn)題的控制微分方程中。利用廣義傅立葉積分和狄拉克函數(shù)性質(zhì)推導(dǎo)出該方程的基本解,繼而利用虛功原理建立邊界積分方程。通過(guò)邊界離散,建立代數(shù)方程。
