摘要
市政工程试验检验涉及面广、类别众多,试验方法千差万别。不同试验方法得到的试验数据不具有对比性,因此需采用某种方法建立这些试验数据之间的联系,以使它们具有对比性。数理统计学中的回归分析方法、相关性分析方法是可行的途径。通过3个实例给出了建立一元线性公式的方法,并验证了该方法的可行性。可供试验工作人员参考。
Due to wide range and many categories involved by the tests and inspections of municipal engineering,the test methods are different.The test data obtained by different methods are not comparable.Therefore,the relationship among these test data should be establish by some method to make them comparable.Regression analysis and correlation analysis in mathematical statistics are feasible ways.The method of establishing univariate linear for-mula is given through three examples and its feasibility is verified.It can be used as a reference for test staff.
