查询词典 data point

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.

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。
