This paper introduces an idea of design and working principle for the phonic realization of wind - tunnel control parameters with the computer of the wind - tunnel control system and a phonic chip. the system structure is simple, economical and practical. the phonic information memorized in analogue has high fidelity effect and is very easy to modify
對火炮身管進行窺膛檢測是常規靶場經常進行的試驗項目，本文從工程實現方面詳細論述了新型光電式火炮身管窺膛檢測系統的組成、功能、工作原理和目前所達到的技術指標。 -
Focused on the nonstationary features and analysis requirements of flutter test data, the application scheme is brought forward for flutter signal processing. by using computer simulation and flutter test of low - speed wind - tunnel of some aeroelastical modes, the characteristics of the scheme are investigated
本文基於顫振試驗信號的非平穩特點與分析需求，應用自適應時頻分析技術給出並實現了兩種新的顫振信號處理方案，重點研究了適用於連續變速顫振試驗的顫振邊界預測問題。 -
Simultaneously, a new fbp criterion is presented based on the gray - lavel and contour for the image of gabor spectrogram and the relation parameter is used to make flutter boundary prediction. the functions of the method are studied by computer simulation and further examined by using several flutter testing data ( low - speed wind - tunnel, high - speed wind tunnel and flight )
本文詳細研究了顫振信號聯合時頻譜圖的特徵，應用圖像邊緣識別方法對顫振信號時頻譜圖的輪廓、灰度進行了綜合分析，給出了一種全新的顫振余量定標量化法，依此量化值完成對顫振邊界的外推。 -
Using the developed computer program the wind flow around a cubic building model, a rectangle - section tall building and a gable - roof building are first numerical predicted, respectively. in the prediction the single - area and multi - area grid refinement approaches are respectively used and the numerical results are compared with the wind - tunnel test results and the numerical results without grid refinement obtained by other researchers. this indicates that the proposed nonstaggered grid and refinement scheme is not only valid and easy to be car
採用編制的計算程序首先對一立方體建築模型、一矩形截面高層建築和一雙坡屋面建築的繞流風場進行了模擬計算，分別採用單域和多域加密方案對建築周圍的網格實施了局部加密，數值模擬結果與風洞試驗結果以及其他研究者的非加密計算結果進行了比較。
