| 摘 要： | 本文从“同温度层不完全平行于地面,且在变化”的“任意分层”假设出发,导出了水准折光修正公式,并利用光的色散效应在10~(-6)的精度要求下,求得r=r_T=h_1/h_2=(n_(01)-1)/(n_(02)-1)=常数最后指出,研制双波长激光水准仪的必要性和可能性,并提出了研制此种仪器的技术参数.

| Abstract: | The authors point out that "The layers with same temperature are not quite parrallel to the ground and are changable tinder different condition" (i.e. the layers are divided arbitrarily). Under such an assumption the correcting formula for refraction in levelling has been derived concerning the effect of light dispersion. The formula with the precision 10-6 is as follows
The necessity and the possibility to develop the two wavelengths laser levelling instrument are suggested and the technical parameter for producing this kind of instrument are put forward too. |
