derivation block
differential element
differentiation element

The automatic differentiation available just can handle a derivative unit . usually , the code of a derivative unit just includes fixed composition
现有的自动微分工具通常只能处理一个微分单元的微分，一个微分单元的代码通常只包括固定的组成结构。
The cell differential matrix equation is founded on the basis of mechanics analysis of the waterwall and superheater tubes . it is computed by the ansys fea software the effect on the heat and stress coupling field of some operation parameters , which is the theory guidance for accelerated lifetime tests and the accurate life evaluation
对水冷壁直管段和过热器弯管段进行力学分析，建立微分单元矩阵方程，应用ansys有限元分析软件定量分析温度、压力等参数对管道运行中热?应力耦合场的影响，验证了寿命评估的准确性。
Based on the condition of static equilibrium , the equation of active granule pressure is derived the height of the action point of the granule pressure on the backface of the linear retaining wall is larege than one third of height of the wall and distribution is nonlinear
摘要通过对直线挡墙背散粒体取微分单元，根据静力平衡条件，推导出直线挡墙主动散粒体压力沿墙高的分布的公式，证明直线挡墙主动散粒体压力沿墙高呈非线性分布，合力作点的位置大于而不是等于或小于墙高的三分之一。
