  1. Abstract : events contributing to the establishment of statistics the science of data and its chemical branch are epitomized. as the new chemical branch named chemometrics or chemstatistics has been disputed in the circles of chemistry for a long time, reasons for adopting chemstatistics are given, which is defined as the science of gathering or generating, describing, summarizing and interpreting the data concerned to acquire new chemical knowledge or information. the fact that many traditional statistical methods, such as significance tests, analysis of variance, regression and correlation, and some others not usually considered statistical, such as model building, monte carlo method, fourier transformation, artificial nerval networks and pattern recognition, each contains one or more of the five connotations of statistics is expounded. the regular pattern that a chemstatistician grows up is approached. the urgent task is to include chemstatistics in the undergraduate or graduate curriculum of chemistry specialty. the goal of the project is to nurture chemists who know statistics

    本文試從通過行政合同與行政合同行為的差異分析入手，進而探索行政合同行為產生的法律關系，並由此提出自己的觀念：行政合同是行政主體為行政目的，與公民、法人和其他組織通過協商方式在意思表示一致的基礎上所達成的協議，它是雙方合意的結果，行政合同行政合同相關問題的法律分析中文提要有且僅有一方當事人為行政主體;而行政合同行為則是行政主體在行政合同訂立、履行、變更和終止過程中發生的行為，它是單方的、具體的;兩者本質明顯不同。
