In physical representation , the non - vanish components of matrix are retarded , advanced green function and the matrix component related with the thermal distribution function 在物理表示中,傳播子只包含三個(gè)分量:推遲、超前格林函數(shù)及與熱分布函數(shù)相關(guān)的矩陣分量。
The rationale regarding the use of the skeletal muscle tissue technique is the availability of a longitudinally oriented basal lamina and extracellular matrix components that direct and enhance regenerating nerve fibers 使用骨骼肌組織修復(fù)神經(jīng)缺損的優(yōu)點(diǎn)在于,它能夠提供縱向延展的基底膜和細(xì)胞外基質(zhì)成分,這些物質(zhì)都可以直接促進(jìn)神經(jīng)纖維的再生。
The composite material , which is used to make muller plow of sand mill , is prepared by the method of cast - infiltration and the technology parameters for making composite material is optimized . then the effects of the matrix component on composite layer also are disccused 通過試驗(yàn)對(duì)利用鑄滲法在鑄件表面獲得一定厚度復(fù)合材料層的形成機(jī)理進(jìn)行了理論分析,優(yōu)選了利用鑄滲法在鑄件表面制備復(fù)合材料的工藝參數(shù)(澆注溫度、合金膏塊的厚度、澆注位置等) 。
From basic equations of elastic mechanics , related knowledge of fracture mechanics and frequent used methods of differential and integral calculus , bending fracture models of anisotropic functionally graded materials is established by assuming that material constants ( stiffness matrix component ) are expressed in arbitrary functions 根據(jù)彈性力學(xué)的基本方程以及斷裂力學(xué)的有關(guān)理論及微積分方法,將材料常數(shù)(剛度系數(shù))設(shè)為空間變量的任意函數(shù),建立了各向異性功能梯度材料板彎曲斷裂模型,即三類偏微分方程邊值問題。
