[Method] Based on the data of annual precipitation in Anyang and Nanyang from 1953 to 2009, the changes of precipitation in Anyang and Nanyang were compared by means of mathematical statistics, regression analysis and wavelet analysis. [Result] In recent 57 years, annual precipitation in Anyang and Nanyang showed decrease trend, especially Anyang with obvious decrease trend; from seasonal variation, average precipitation in spring and winter went up in Anyang and went down in Nanyang, while average precipitation in summer and autumn reduced in two cities; from periodic variation, when the time scale of precipitation in Anyang was 12-15 years, there was a catastrophe point in 1970, and Nanyang had two catastrophe points in 1965 and 1997 when the time scale of precipitation was 15 years and 4 catastrophe points in 1968, 1978, 1987 and 1999 when time scale was 7-10 years. [Conclusion] The study could provide theoretical foundation for the forecast of local climate changes.展开更多

The diagnosis of all 11 cases was confirmed by bariummeal roentgenography. After intubation, all the patients could take liquid or soft diet by mouth.There was no operative mortality and the patients survived 2 to 14 months (mean5.7 months). All of them could take food by mouth before death. The clinical application proved that the intubation has been a safe and suitable management.展开更多

After the change of history and the alternation of times, there are many kinds of ancient buildings and traditional houses in the ancient city. Combined with the current development of the ancient city, through the combination of actual research and questionnaire survey, clarify the current development problems, according to the principle of combining protection and renewal, put forward the feasibility of solving problems from the management concept and technology, and clarify the development direction of the ancient city.展开更多
