Y-2衍射仪(图1)为结构分析通用设备,不带有应力测定仪那样的平行光阑,且计数管最大2θ只达157°(拆除限位开关后亦只达159°),不能满足应力测定的要求。
The Y-2 diffractometer (Figure 1) is a general-purpose structural analysis unit that does not have a parallel diaphragm such as a stress-gage and has a count tube maximum of 2θ of only 157 ° (only 159 ° when the limit switch is removed) Meet the stress measurement requirements.
