By using of GEODYNⅡ from GSFC/NASA/USA and newly lunar gravity model LP165P from JPL/NASA/USA,the effects on the orbit revolutionary from different models by truncation to some degree and order are simulated and computed,the orbit revolutionary and analysis of orbital lifetime under different height,inclination and ellipticity with same lunar gravity model are computed.
The “twice loosed shoe”method tries to discuss Wheeler-DeWitt equation by fixing the cosmological scalar factor a and the scalar field Φin turn. This method can conquer the great field difficulty caused by only considering the tunnelling effect of the birth of the quantum universe. The potential well effect of the field Φprovides the probability truncation.
The results show that high inclination circular high orbit(150 km or 200 km) has better performance,with its orbit lasting more than one year without(alignment,) and its orbit can be computed with gravity model truncated in degree and order 100 without losing its accuracy.
The entropy has both linearly and logarithmically divergent terms, where the linearly divergent term can reduce to the form proportional to the event horizon area if the temperature is replaced by the Hawking temperature and the coordinate cutoff is replaced by the proper cutoff;
With the new lunar gravity models LP165P and GLGM-2,we analyze the character of the lunar gravity field,compute corresponding degree-wise rms, and give gravity anomaly distribution figures at different height of the two models. Then we analyze and compare the character and difference of the lunar gravity models truncating to different orders and degrees at different height.
