本试验方法不仅适用于热双金属横向弯曲的测量，也适用于其他材料横向弯曲的测量。
This test method is not limited to thermostat metals and can be used for other materials for which the cross curvature must be measured accurately.
钻柱横向非线性振动的基频随着初弯曲最大挠度的增大而减小，初弯曲对钻柱横向非线性振动基频的影响随钻柱长度的增大而增大，随轴向压力的影响而增加。
The effect of initial deflection on the first frequency increased with either the length of drill stem or the axial compressive force on the drill stem increases.
