However, the sparsity of the observational points used in the refraction method due to the restrictions imposed by the surface hypsography of the area-- one point per kilometre-- makes it possible only to give relatively accurate data for base rock velocities, but not for morphologic structure configurations.

但是，小折射方法受地表的地形起伏因素影响比较大，且观测密度也不够，每公里只有一个点，所以在该区只能较准确地给出基岩的速度信息，而无法准确地获得基岩的形态起伏数据。

However, owing to the much restricted hypsography of the surface for the refraction method and the insufficient surveying points --only one observational point a kilometre, we can only provide relatively true velocities of the base rock, but cannot obtain the accurate data of the morphologic-structural configuration.

但是，小折射方法受地表的地形起伏因素影响比较大，且观测密度也不够，每公里只有一个点，所以在该区只能较准确地给出基岩的速度信息，而无法准确地获得基岩的形态起伏数据。
