| 9. | The global distribution of nssr can be provided by means of satellite remote sensing . in this paper a new parameterization derived by li zhan - qing ( li model ) in 1995 was used to compute the net surface solar radiation for 18 stations of chinese main land on some days over january and february in 2001 . after compared the results of li model with those derived from a model ( li - leighton model ) and b model ( langley parameter model ) for clear - sky and cloud - sky respectively , we founded that the relative difference of the two model are below 6 %
结果表明：在晴天情况下， li模式与a模式很相近，而与b模式结果差别较大，因为b模式在晴空条件下是不准确的，这也可以从a模式与b模式的差别看出；在云天情况下， li模式与b模式结果尽管有些差异，但是相似性仍然很好，除了个别的台站外，绝大部分台站两者的相对差在6以内。 |
| 10. | According to the gravity - elasticity similar law the model scale of bai shan pumped - storage hydroelectric plants is taken as the trashrack bar is made of zinc , the relative errors between its practical density and elastic modulus and its proper values are - 7 . 82 % and + 1 . 43 % , respectively . by lvs measuring the velocity distribution ahead the trashrack bar and on the basis of the velocity distribution the working conditions of the pumped - stroage hydroelectric plant are controled . the dynamic strain of the trashrack bar induced by flow are measured using strain slips
