求翻译：辐照时间越长，剂量片吸收的剂量值越大，发光曲线的积分值也越大，剂量值与辐照时间的关系可以采用最小二乘法进行拟合；拟合得到的直线斜率不同说明辐照源的活度不同。是什么意思？

Longer irradiation time, the greater the dose tablets absorbed dose values, the integral value of the light curve, the relationship of dose values ​​and exposure time were fitted by the least squares method; obtained by fitting a straight line the slope of a different description of the convergence

The longer exposure time, the dose is absorbed dose, the greater the value of the integral values light curve, the larger the dose, duration of exposure to radiation can be used to multiply the minimum 2, to be fitted by a straight line with slope on different sources of radiation in different degre

The exposure time is longer, the dosage piece absorption dosage is bigger, the illumination curve integral valve is also bigger, the dosage and the exposure time relations may use the least squares method to carry on the fitting; The fitting obtains the straight line slope different explanation sour

Irradiating the longer, larger doses absorbed-dose values, integral values of the light curve is also bigger, dose and irradiation time to value with least square fitting; fitting straight lines are different slope describes the activity of different radiation sources.
