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

    文摘:本文追溯了統計學發展、建立中的大事，陳述了它的定義及其化學分支發展、建立的梗概；鑒于化學界對該新興化學分支學科的名稱長期存在爭議，提出了以化學統計學而不以化學計量學為該學科名稱的理由，把化學統計學定義為一個研究有關數據的收集或產生、描述、分析、綜合和解釋，以獲得新化學知識或信息的學科；闡明了許多公認屬于統計學的方法，如顯著性檢驗、方差分析、回歸和相關，以及一些尚未認定屬于統計學的方法，如模型建立、蒙特卡羅方法、傅立葉變換和人工神經網路，都含有統計學5個內涵中的一個或多個；探討了化學統計學家成長的模式，認為當務之急是把化學統計學納入化學專業的教學計劃，以培養懂統計學的化學家。
