查询词典 partial cross section

Fourthly, the resonance structure disappears in the energy dependence of integral cross-section due to the summation of partial waves.

在相同入射能的情况下，总散射截面随转动量子数j的增大而显著增大，随量子数m的增加而减小。

Theoretical calculation of the partial cross section for He-HF collision system

He-HF碰撞体系分波截面的理论计算

Then the stability solution of the variable cross-section compression bar, that is discribed by a partial differential equation with variable coefficient is transformed into solving a set of algebraic equations established in the subspace.

首先以均匀梁的低阶纵向振动模態函数构成求解子空间，然后在此子空间中把变截面压桿稳定由变系数偏微分方程描述的求解问题转化为非线性代数方程组的求解，从而简化了计算过程。

When the partial composite beams are loaded, the interface of steel and concrete would generate slips. The slips make the assumption of plane cross section disaccorded and decrease the stiffness, so stress and deflection are affected by the slips rather deeply.

部分剪力连接在承受外荷载时，钢与混凝土的交界面上会产生滑移，而滑移使组合截面不符合平截面假定，结构的刚度也会减小，因此截面应力和挠度变形受滑移的影响比较大。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
