一、示值误差的校准1.被校对象氯化氢气体检测报警器,测量范围:0~20μmol/mol、0~50μmol/mol。2.校准方法在正常工作条件下,仪器通电预热稳定后,按照使用说明书标定仪器,先通入零点气体校准仪器的零点,再通入浓度约为满量程80%的气体标准物质,预吸附一定时间后校准仪器。然后分别通入浓度约为满量程20%、50%和80%的气体标准物质,记录仪器稳定示值,每种浓度重复测量3次,

在传统的制造工艺中,环面蜗轮滚刀刀齿的顶后角面由手工磨削,不能保证滚刀刀齿刃带面的宽度;滚刀的每一个几何特征曲面是通过不同的制造工艺采用不同的机床加工生成,工艺繁琐且制造效率低。为了简化滚刀制造工艺,提高制造效率和刃带面的制造精度,本文提出一种滚刀半自动计算机辅助设计(Computer aided design,CAD)方法。首先建立滚刀螺旋面和侧后角面数学模型,在此基础上提出一种滚刀刀齿顶后角面
