Shallow earth temperature is influenced by surface temperature change everyday and every year, topographic change, elevation change and surface feature change, so it should be corrected.

浅层地温受到地表气温的日、年变化、地形变化、高程变化和地貌变化等的影响，应对实测值进行相应校正。

Soundness of the rock surface must be included in the topographic study.

岩石表面的坚固性，必须包括在地形研究之内。

So, instead of'intermediate layer correction', we should adopt free air gravity anomaly and'topographic trend surface correction', which result in topographic trend surface free air gravity anomaly.

为此，应当不做“中间层校正”，而应代之采用自由空气重力异常加上“地形趋势面校正”之结果，以形成地形趋势面自由空气重力异常。

The practical part of the seminar (field survey) on documentation works including making topographic maps and archaeological survey (putting GPS points of archaeological sites, collect surface materials) will be conducted at the archaeological site Kanka (200 km. from Tashkent).
