test region meaning in English
试验区
Examples
- Unlike in subsonic and transonic speed regimes, the interference resulting from the finite size of the test region is seldom present .
不像在亚、跨音速区域，这里因试验段尺寸有限造成的干扰是难得存在的。 - Viewpoints on building modern agricultural equipments test region in heilongjiang reclamation area
发挥农垦现代化农机装备优势推进全省农机跨区作业 - Best test regions are confirmed to found the acoustic emission test method for valve leakage . the large amount of data collected also allowed a brief investigation of the effects of different opening , valve types , differential pressure and leakage rates
根据本次研究工作的目的和特点并结合现场的实际情况，探讨了内漏时阀门开度、阀门类型、两侧压差以及泄漏率等因素变化时的声学特性。 - First , it was taken that a discuss about the effects of geometry parameters of each piezocrystal on direction parameters ( main lobe width , side lobe amplitude , elimination of grating lobes ) , amplitude of ultrasonic pressure , element viberation pattern , mutual radiation among elements , efficient test regions , ability to keep accurate and near - field distance and so on . based on the direction of ultrasonic field in ulpa deduced by ourselves . in addition , on the base of integrating all kinds of factors , it was put forward that the principle and method for optimized design of geometry parameters of piezocrystals in ulpa transducer , and its design programme and interface were compiled
首先在推导超声相控线阵换能器声场的指向性的基础上，就各个晶片几何参数对指向性指标(主瓣宽度、旁瓣幅度、消除栅瓣) 、声压幅值、阵元振动模式、阵元间互辐射、有效检测区域、精确控制能力、近场长度等方面的影响进行了论述，并在综合各方面影响的基础上，提出了晶片几何参数优化设计的原则和方法，编写了设计程序和界面。 - Compare a lot of face image characteristic vector with face image sets characteristic matrix in order to get their similarity , and find the least value of similarity as threshold . in the detecting phase , compute the similarity between characteristic vector of testing region in gray image and face image sets characteristic matrix , if the similarity bigger or equal to threshold then the testing region is a human face , otherwise is not
然后，用大量的人脸图像的特征向量与人脸图像集特征矩阵比较它们的相似程度，找出值小相似度，并把这个最小相似度作为阈值；在检测阶段，求出灰度图像的待测区域的特征向量与人脸特征矩阵的相似度，若该相似度大于等于阈值，则是人脸，否则不是人脸。
