The mixture is then distilled in vacuo . 然后将混合物进行真空蒸馏。
2.
The cortical atrophy leads to compensatory dilation of the cerebral ventricles known as " hydrocephalus ex vacuo " 皮质萎缩导致脑室代偿性扩大，诸如众所周知的脑积水。
3.
According to phenomena observed during total solar eclipse , it can be pointed out that the velocity of gravitational field wave is equal to the velocity of light in vacuo 摘要据日全食时的现象能够得出：在真空中，引力波的传播速度和光波的传播速度相等。
4.
Then fourier transformation is employed to solve equations of motion of the rings , bulkheads , stringers and fluid respectively , with their reactions ( moments ) expanded by the shell ' s in - vacuo modes . by means of continuity conditions on the interfaces between the shell and the stiffeners as well as the fluid , and inverse fourier transformation , the modal reactions ( moments ) are finally expressed by the shell ' s modal velocities 然后用fourier变换分别求解环肋、舱壁、纵骨和流场的运动方程，将它们对壳体的作用力(力矩)用壳体周向模态展开，利用它们与壳体在连接处位移连续条件以及fourier逆变换得到用壳体速度表示的模态相互作用力(力矩) 。
