Abstract: Checking and measuring the verticality is very important in the vertical control of high-rise building const ruction.
文摘：垂直度检测在高层建筑施工的竖向控制中十分重要。
In view of these problems, the paper put forward some countermeasures for strengthening tourist highway network const ruction in this region.
针对上述问题，本文提出了加强该区旅游公路交通网络建设的对策。
A beam as the base of rail must have strong strength, rigidity, small subsequent creep camber, and excellent durability as well as rapid in const ruction.
桥梁不仅应有足够的强度、刚度以及小的后期徐变变形，同时还应具有良好的耐久性，并且要求实现快速施工。
All-field electroretinogram (ERG) can only estimate the ruction of retina in total, at the same time, local-field ERG can only test a small region of retina every time.
全视野视网膜电图只能对视网膜功能进行整体评价，局部视网膜电图一次只能测试视网膜少量区域。
