Before clamping, to check the template, especially the template Panel connection 技术上来说,格林函数,,伴随着一个在流形中作用的线性算子 ,为以下方程式的解 其中 为狄拉克 函数。此技巧可用来解下列形式的微分方程: 若的 核是非平凡的,则格林函数不只一个。不过,实际上因着对称性、边界条件或其他的因素,可以找到唯一的格林函数。一般来说,格林函数只需是一种数学分布即可,不一定要具有一般函数的特性。 格林函数在凝聚态物理学中常被使用,因为格林函数允许扩散方程式有较高的精度。在量子力学中,哈密顿算子的格林函数和状态密度有重要的关系。由于扩散方程式和薛定谔方程有类似的数学结构,因此两者对应的格林函数也相当接近。 动机 若可找到线性算符 的格林函数 ,则可将 (1) 式两侧同乘,再对变量 积分,可得: 由公式 (2) 可知上式的等号右侧等于 ,因此: 由于算符 为线式,且只对变量 作用,不对被积分的变量 作用),所以可以将等号右边的算符 移到积分符号以外,可得: 而以下的式子也会成立: good processing performance, with sufficient rigidity. Template selected template surface should be flat and smooth, plywood coated high strength, good wear resistance, water resistance, durability, physical and chemical properties of stable and smooth surface, no pollution, no damage, clean. Template straight keel, specifications, and panels close, firmly attached, have sufficient rigidity.
