I already introduced, as you see there length, time and mass and we call these the three fundamental quantities in physics.
我已经讲过，长度、时间、质量，它们被称为，三个基本物理量。

The fundamental formula of large deformation, when the deflection is of the same order as the length of the shell, is derived exactly for cylindrical shell under cylindrical deformation.
当薄壳为柱形且作柱状弯曲时，精确地求得了壳的挠度与长度同级的大变形基本公式。

The conversion efficiency between the fundamental wave and the th emission is roughly constant over the length of the plasma channels.
