【摘要】 应用微核测定法研究了匀强磁场的致突变效应。结果表明:1.在0～5000G.S范围内,微核细胞率与照射剂量呈线性关系（r=0.9871823）。以最小二乘法进行回归分析,得到经验回归直线Y=2.81904762+0.00126571D。2.在3000G.S时,在0～180分钟的范围内,微核细胞率与照射时间增长呈非线性关系。用多项式回归分析,得到经验多项式回归曲线Y=3.731464+1.751274t-0.1680962t²+0.002084t^?+0.0001321t⁴（r=0.9276326）。更多还原

【Abstract】 Mutagenic effect of uniform magne-tic field was studied using micronucleusas indicator.Result of experiment showedthat (1) in the range of 0-5000Gs,thefrequency of micronuclear cell and rad-iation dose was in linear relationship(r=0.9871823).Through l(?)ast squares linearregression analysis,empirical regressionlinear is gained.(Y=2.81904762+0.00126571D)(2) In the range of 3000 Gs from 0-180minutes,the frequency of micronuclearcell and the increase of radiation timeis in non-linear relationship. Through multinomial regression an-alysis,empirical multinomial regressioncurve is gained.Y=3.731464+1.751274t-0.1680962t~2+0.002084t~3+0.0001321t~4(r=0.9276326)更多还原
