  1. The precipitation and temperature both existed 5year periodic variation in the pre - flood period in the south of china

    華南前汛期降水和氣溫都有5a的主周期。
  2. Another is maximum allowable dispatching the effectiveness of flood control and actives. with the extension of hydrological observation data and accumulation of reservoir operation experiments, periodic analysis and research the reservoir design flood is basic of operating above two aspects

    隨著水文觀測資料的延續和水庫運行經驗的積累，定期對水庫設計洪水進行分析研究是保證水庫實現上述兩大職責的基礎。
  3. With the meteorological and hydrographic data in songhuajiang and nenjiang valley from 1951 to 1995, using correlation analysis and empirical orthogonal analysis, the rule of the flood and relation between flood and precipitation distribution in this region are discussed. the results show that periodic change of water level is obvious in this region. now water level is in the serious stage from 1980 ' s. there are great relation between the water level of flood period and the precipitation. the unusual precipitation of nenjiang valley has greater impact than that of second songhuajiang valley. at the summer in 1998, songhuajiang and nenjiang valley encountered the ghastly flood and the reason for that is the anomalous precipitation great exceeding the historic maximum

    利用松花江，嫩江流域1951 1995年期間的氣象和水文資料，採用相關分析，經驗正交分析等方法，討論了該流域洪澇發生的規律及其與流域內降水分佈的關系.文章指出，江流域的水位變化有明顯的階段性，且具有全流域一致的特性，目前正處在80年代以來洪澇較嚴重的階段;嫩江流域降水異常偏多對松花江洪澇的影響比第二松花江的作用要大; 1998年夏季，松花江，嫩江流域出現超歷史紀錄特大洪水的關鍵原因是嫩江流域6 8月的降水距平百分率遠遠超過了歷史上的的最大值
  4. The periodic variation of ssta of the two key regions combine reflect vary length periodic variation of flood season precipitation anomalies in liaoning areas

    兩關鍵區ssta周期特徵反映遼寧汛期降水異常的不同長度周期特徵，且有很好的互補關系。
  5. ( 3 ) the precipitation anomaly existed 3year. 5year 7year 14year periodic variation in the pre - flood period in the south of china. the temperature anomaly existed 2year 4year 5year 12year 19year periodic variation in the pre - flood period in the south of china

    （ 3 ）華南前汛期降水異常存在3a 、 5a 、 7a的年際周期和14a的年代際周期；華南前汛期氣溫異常存在的2a 、 4a 、 5a的年際周期及12a 、 19a的年代際周期。
  6. ( 2 ) the precipitation shows periodic variation of 2 - 4 years in the four seasons and significant 10 - 12 years periodic variation in summer and flood season. ( 3 ) liaoning flood season precipitation anomalies in phase with huabei and dongbei, jiangnan inverse

    在周期上，遼寧四季降水的3年左右振蕩特徵較為一致，夏季和汛期的10 12年周期顯著。遼寧汛期多少雨年同期華北、東北與之同位相，江南與之反位相。
