flat gradient

Based on field measuring, a temperature field and temperature gradient curve of steel flat box beam are presented. In this temperature gradient curve, the sunshine temperature difference between roof and floor is high to 30 ℃.

结合大量现场试验，提出了符合工程实际的日照温差下带人行道翼缘的扁平钢箱梁温度梯度模式和竖向及横向的温度梯度曲线公式，其顶底板日照温差可达30℃。

The numerical results show that the influences of gradient parameter on the contact stress, contact area and maximum indentation depth are stronger when a functionally graded coated half-space is indented by a rigid flat circular indenter or a rigid spherical indenter.

数值方法求解表明：功能梯度材料涂层半空间在刚性柱形压头和球形压头作用下，接触表面分布应力，接触半径以及最大压痕受材料梯度效应的影响较大。
