灰色数列模型对水泥粉尘容许浓度的研究

应用灰色数列模型寿命表法对接尘工人连续工作３０年，控制尘肺患病率在１％的条件下，水泥粉尘作业场所的粉尘容许浓度为１６．８ｍｇ／ｍ３。同时采用直线与曲线回归进行拟合预测，选择相关指数较优的模型对数回归，现场水泥粉尘容许浓度为２４．３ｍｇ／ｍ３。灰色数列模型、对数回归方程与实际概率单位误差分析，ＧＭ（１，１）的误差较小，拟合度较好，现场粉尘容许浓度合理严格。

Study on grey mathematical arrays model for the allowable concentration of cement dust

Under the control of 1% pneumoconiosis prevalence rate. daest expo bed 30 years' standingworkers' bad been calculated by using the grel mathematical arrays (G. M.A. ) life table, the alloable concentration cement dust in the operation area must be 16.8 mg/m3. Simultaneuosly,fitting calcua non of linear and curie regresstion and optitnization of the related index model logarithm regresstion.the allowable con centration cement dust must be 24. 3 ma/m~.Comparing the results of error anallsis between G.M. A. model and a ctual probability, it showsthat the former's error is smaller and fitting decree is batter than take latter, and the allowable concen iration is reasonable and strict.
