  1. 航空发动机在高空台上模拟标准大气条件试验的性能研究

    Performance Investigation of Aero-engine Ground Test Under Standard Atmosphere in ATF

  2. 增益矩阵在标准大气条件下设计,并通过相似理论将其扩展到全线。

    Gain matrix K is a constant matrix design at sea-level static condition , and should be transformed to actual flight condition with similarity correction factors .

  3. 但在标准大气条件下,由于几类误差相互抵消,因此近距离测定强对流云回波顶高精度较高。

    But echo top height errors are negligible in short range under standard condition of the atmosphere because errors cansed by several factors counteract each other , BO the radar measurements of convective cloud top heights are quite accurate .

  4. 详细分析了影响电视跟踪系统作用距离的因素,分析了目标、天空背景在电视像面的照度和对比度,建立了标准大气条件下,电视系统作用距离的数学模型。

    It discusses the factors that affect the effective distance of TV , analyzes the lum and contrast of targets and sky background on the imaging surface of TV . A mathematic model of effective distance of TV under the standard air condition is also constructed .
