常見(jiàn)例句

There is a close correlation between sea level slope and height datum, in which geodesylists and oceanographers are interested.
海面傾斜與高程基準(zhǔn)密切相關(guān)，它已經(jīng)受到大地測(cè)量學(xué)界和海洋學(xué)界的重視。
The reason why GPS leveling cant be used for height transfer across obstacle is that the height datum of both sides of obstacle is not consistent.
GPS水準(zhǔn)無(wú)法直接應(yīng)用于跨障礙高程傳遞，其關(guān)鍵原因在于障礙物兩側(cè)的高程基準(zhǔn)不一致。
The key of GPS leveling across sea is that the height datum on each side of channel is not consistent, so the general geometrical fitting method can not be used directly.
GPS跨海水準(zhǔn)的關(guān)鍵問(wèn)題是海峽兩側(cè)的高程基準(zhǔn)不一致，因此無(wú)法采用常規(guī)的數(shù)值擬合方法。
