Then the periodic properties of geocenter motion in the x, y, z components are summarized. considering the statistical precision of the gps observations, the geometrical distribution of gps stations and their physical stablility, a new method to determine the parameters of geocenter motion is studied and analyzed. in order to have a better understanding of its effect on the height datum origin, the rule of geocenter motion in the horizontal and vertical components are also analyzed and some useful conclusions are drawn
提出了將譜分析與抗差估計相結合的抗差譜分析方法，並用該方法分析了地心運動時間序列的主要周期特性；為合理地確定地心運動參數，詳細研究與分析了一種新的定權方法對求解地心運動參數的作用，該方法充分利用了gps觀測量的統計精度、點位的幾何分佈以及物理穩定性；為了明確地心運動導致的高程基準的變化，分析了地心運動對地面點的水平分量和垂直分量的影響規律。 -
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 -
Because spamassassin can learn over time and access dynamic databases, even without installing the periodic rule updates, it is more likely to remain useful for a longer time than strictly rule - based systems
因為spamassassin可以不斷地學習和訪問動態數據庫，甚至無需安裝定期規則更新，所以與嚴格基於規則的系統相比，它更可能長時間地使用。 -
An improved one - dimensional ca traffic model was proposed to describe the freeway traffic under the periodic boundary conditions. this model was based on the nasch model, it can describe stop - and - go traffic, which gives a better description of the phenomena observed on highways with a slow - to - start rule
在元胞自動機交通nasch模型和fi模型的基礎上，基於交通流中實際車輛的慢起動行為，進一步提出一種新的一維交通流元胞自動機模型，在臨界密度附近，存在著亞穩態和滯后現象。 -
