缺陷
It can also take care of some plate girder defections, such as residual stresses and initial bending. 它还可以考虑梁的初始缺陷，如残余应力和初弯曲。
The instrument overcomes the inherent defections of the old instrument, and gains data automatic test and analysis.Hence, the intelligent instrument design is realized. 光强度自动测试仪在性能上不仅克服了传统仪器的固有缺陷，而且达到自动测试与分析的目的，实现了仪器的智能化设计。
