In deep sea, sound ray bendingcorrection has to be done in order to achieve high precision of the calibration.
在深海，必须进行声线弯曲修正才可获得高精度校准结果。

Curve flexibility may dictate the degree of the fulcrum bendingcorrection index, whereby a curve that is less flexible may achieve a greater fulcrum bendingcorrection index.
曲线的弯曲度可能指明了支点弯曲矫正指数的程度，然而较不弯曲的曲线可能达到更大的支点弯曲矫正度指数。

Combined with the calibration method, two methods for the sound ray bendingcorrection in deep sea are developed when the sound velocity profile is known and unknown separately.
