rotational inertia meaning in Chinese
【物理学】转动惯量。
Examples
- Technically , the helium ' s rotational inertia decreases
用专有名词来说明，就是氦的转动惯量降低了。 - Chan and kim observed such a decrease of rotational inertia in a ring of solid helium
陈鸿渭与金恩成在一圈固态氦中，观察到这种转动惯量减少的情形。 - The rotational inertia of an arbitrarily triangle uniform plane is calculated by a simple method . it is pointed out that principal axes can be deduced from the calculation
摘要用一种简单的方法计算了均质的任意三角形平板刚体的转动惯量，并由此结果给出一般三角形的惯量主轴。 - The period of these torsional oscillations depended on the rotational inertia of the helium ; the oscillations occurred more rapidly when the inertia went down , just as if the mass of the helium decreased
这种扭转振?的周期取决于氦的转动惯量，转动惯量减少时振?加快，看起来好像是氦的质量减少了。 - The equations of motion governing the axisymmetric elastic deformation of finite orthotropic cylindrical shells , involving the effect of transverse shear and rotational inertia , are derived . by applying the reverberation method , the displacement and the resultant forces of the shell in the phase space are expressed . then the transient waves in the finite orthotropic cylindrical shell subjected to the axisymmetric impact are obtained by using inverse laplace transforms . furthermore , the transient solutions are decomposed to the generalized ray integrals and computed numerically
分析了计及剪切变形和转动惯性的有限长正交异性圆柱壳中弹性瞬态波的传播问题，采用回传矩阵法，在相空间中给出了位移和内力的表达式。再利用laplace逆变换，得到正交异性圆柱壳受轴对称冲击作用时弹性瞬态波解，然后将其分解为若干广义射线积分之和，并用数值方法求解之。
