風微擾 的英文怎麼說
中文拼音 [fēngwéirǎo]
風微擾
英文
chopping of wind-
The analyzed and contrasted results of the distribution of the surface pressure distributions and the sectional side forces with the former results of the slender body in the same flow conditions show that the shm ' s control effect to the slender body is due to that the two asymmetric vortices over the slender body model are sensitive to the nose perturbations
通過對物面壓力分佈、截面側向力分佈和以前細長旋成體結果的對比和分析,發現單孔位微吹氣擾動對于細長旋成體橫側向控製作用在於模型頭部背風側非對稱二渦結構對擾動的敏感性。At the same time, the dynamic response of structure under environmental excitation such as ground micro - earthquake, vehicle vibration and wind vibration, is usually disturbed with noise. thereby, the signal - to - noise ratio of data collected by sensors is rather low
同時,結構在環境激勵(如:地面微震、車輛振動或者風振等)作用下的響應信號由於受到噪聲干擾,儀器所能採集到的信號信噪比較低,而且是非平穩信號。The complete air - cooled control system has been realized by at89c52 microprocessor and icl7109 the integral adc which has high counter - interference capability. the main circuit uses non - contract solid module and has the characteristics of high speed switching off and avoiding contract burned to stop blower fan
該系統採用at89c52微處理器及抗干擾能力強的積分型模數轉換器件icl7109實現數據的採集及處理,實現了完整的風冷控制系統功能;主迴路採用無觸點固體模塊,具有關斷速度快、避免觸點燒壞、導致風機停運的特點。The paper considers a risk model with negative risk sum perturbed by diffusion. the integro - differential equation and the explicit expression for the ruin probability are derived
