校测 meaning in English

calibration
corrective gauging

The calibration of a closed throat will not suffice if the walls are removed to make an open throat .
如拆走洞壁形成一个开口试验段，则闭口试验段用的校测结果就不够充分了。
In this dissertation , with the background of wind tunnel reconstruction of one country key project , nozzle design and flow field - testing is studied
本文以国家某重点工程的风洞改造项目为背景,研究了m7 、 8喷管设计及流场校测等问题。
Using the system designed in this thesis work , flow field calibration of the wind tunnel is accomplished , which covers dynamic pressure drop coefficient , dynamic pressure time stability , axial static pressure gradient , boundary layer , and degree of turbulence , etc . boundary layer measuring principle and method are especially described in detail , the relationship between boundary layer thickness , wind speed setting , and the depth of the experimental section is summarized , and finally the calibration data for th e model center zone under specific wind speed are given
然后利用本文设计的系统完成了落差系数、动压时间稳定姓、轴向静压梯度、边界层及湍流度等内容的流场校测。特别对边界层测量的原理及方法做了较详尽的叙述，总结出边界层厚度与设定风速、实验段深度的关系，然后给出模型中心区一定风速下校正数值。
