电势梯度

例如由重力势梯度给出的重力场，或由电势梯度给出的电场。

For example , the electric field or gravitational field is given by the gradient of the gravitational or electric potential .

依据非平衡态热力学建立了混凝土中应变梯度和电势梯度、应变梯此汉理卜人学附士学位论文度和电场强度等力电关系的数学模型。

( S ) According to nonequilibrium thermodynamics , a mathematical model on the relationship between strain gradient and electric potential gradient is presented .

结果表明测量敏感区域为发射电极到测量电极的弧形区域，在发射电极到测量电极的电势梯度线上，测量敏感函数近似于一个指数函数。

Then , the gradient of the potential is acquired according to the numerical computation . The result shows that the sensitivity field has an arc-shape within the region from transmitting electrode to measuring electrode , and it can be expressed approximately using an exponential function .
