| 摘 要： | 在确定的函数关系(数学模型)中,因变量(输出量)随自变量(输入量)的变化规律完全由数学逻辑所确定,自变量到因变量的传递系数(灵敏系数)也可由因变量的标准差和自变量的标准差之比所决定,而与自变量的来历(测量的或者给定的)没有关系[1].本文根据这一基本原理,采用模拟自变量随机变化的方法,成功计算了手持式激光测距仪的测距固定偏差和比例偏差系数的测量不确定度,从而计算出测距标准差综合评定的扩展不确定度,同时解决了复杂的数学模型中多个输入量到输出量的灵敏系数和输出量的不确定度的计算问题.

| Abstract: | The given definite function formula there will obtain certainty result only derived from variations,and relation transmit(sensitive) coefficient between the result and variation is also regarded as the ratio betwwen the standard deviation of result and the standard deviation of variations.But it is no relational that the variations were from surveying or by given.According to this basic principle and letting the variations change randomly,we have triumphantly calculated that uncertainty of measurement for result about distant inherent error;proportion error factor and distant''s standard deviation of Hand-held Laser Distant Meter in this paper,and let it be not difficulty to calculate that uncertainty of measurement for result and sensitive factor estimated from complicated mathematical mode contained so much import variations. |
