摘要
借助传热学基本理论对体吸收型激光能量计因热辐射、热对流和热传导造成的热能损失进行了分析,在此基础上建立了能量计热能损失的数学模型。根据数学模型采用最小二乘法对测量数据进行了曲线拟合,得到与实际降温曲线非常接近的拟合曲线。利用拟合曲线对测量数据进行补偿修正后使得能量计的测量重复性得到了很大提高。该方法对于体吸收型激光能量计的研制具有一定的理论意义。
Abstract
The thermal energy loss of the bulk absorption laser energy meter caused by the thermal radiation,heat convection and conduction was analyzed based on the basic heat-transfer theory. The mathematical model of thermal loss for the energy meter is established according to the analytical result. The curves of the measured data were fitted with the math model and least square method. The fitted curve is quite similar to the actual curve of the temperature drop. The measurement repeatability of the energy meter is improved greatly after the measured data is compensated and corrected by the fitted curve. The work is useful for the development of bulk absorption laser energy meters.
