Unlike in subsonic and transonic speed regimes, the interference resulting from the finite size of the test region is seldom present . 不像在亞、跨音速區(qū)域,這里因試驗(yàn)段尺寸有限造成的干擾是難得存在的。

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 根據(jù)本次研究工作的目的和特點(diǎn)并結(jié)合現(xiàn)場(chǎng)的實(shí)際情況,探討了內(nèi)漏時(shí)閥門開度、閥門類型、兩側(cè)壓差以及泄漏率等因素變化時(shí)的聲學(xué)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 首先在推導(dǎo)超聲相控線陣換能器聲場(chǎng)的指向性的基礎(chǔ)上,就各個(gè)晶片幾何參數(shù)對(duì)指向性指標(biāo)(主瓣寬度、旁瓣幅度、消除柵瓣)、聲壓幅值、陣元振動(dòng)模式、陣元間互輻射、有效檢測(cè)區(qū)域、精確控制能力、近場(chǎng)長(zhǎng)度等方面的影響進(jìn)行了論述,并在綜合各方面影響的基礎(chǔ)上,提出了晶片幾何參數(shù)優(yōu)化設(shè)計(jì)的原則和方法,編寫了設(shè)計(jì)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,用大量的人臉圖像的特征向量與人臉圖像集特征矩陣比較它們的相似程度,找出值小相似度,并把這個(gè)最小相似度作為閾值;在檢測(cè)階段,求出灰度圖像的待測(cè)區(qū)域的特征向量與人臉特征矩陣的相似度,若該相似度大于等于閾值,則是人臉,否則不是人臉。
