但是，基於移相器的普通相控陣天線在進行寬帶寬角掃描時，由於渡越時間和孔徑效應的影響，使信號的瞬時帶寬受限。After thoroughly analyzing the influence of each pump parameters on the gear pump performance, the paper developes the criterion for optimum gear parameters, which can be utilizied in practice easily for gear manufacturing using normal involute gear hob with two - fillet type. the conclutions studied by the paper are : 1. both the addendum coefficient and the deddendum coefficient of the pump gear should be 1. 125
以目前國內普遍使用的雙圓弧頭全齒高為2 . 5倍模數漸開線標準滾刀作為泵齒輪的加工刀具，通過對齒輪加工原理的分析，提出了欲使泵齒輪參數達到最佳，泵齒輪的齒頂高系數和齒根高系數都為1 . 125 ；對變位系數的確定應考慮到泵齒輪的根切、齒頂厚、重合度以及側隙因素；泵齒輪為避免過渡曲線干涉，必然要存在根切現象。The octopus can be bought from customer service centres of mtr, airport express, kcr light rail, kmb and nwfb, ticket offices of kcr east rail and octopus service centre of nwff
普通八達通卡可在地鐵、機場快線、九廣輕鐵、九巴及新巴的客務中心、九廣東鐵票務處，以及新渡輪的八達通服務中心選購。Then, taking into account the effect of the compression of the approach roadway and the differential slope of the bridge slab, the author analyzes the dynamic response of man - vehicle - road system when the vehicle approaches and leaves the bridge by means of laplace transform, the curve of man ' s acceleration versus time, the vertical force between the vehicle and road versus time, the man ' s maximum transient vibration value and the maximum force between the vehicle and road are got, and the program about the calculating progress above are edited. based on the analysis above, the influence on the maximum transient vibration value of some parameters about the vehicle and road such as the movement direction and speed and weight of the vehicle, the differential slope of the bridge slab and the length of the approach slab, are studied, and some conclusion are given
分上橋和下橋兩種情況，考慮車路耦合和橋面沉降坡差的影響，對車輛通過設和不設搭板的路橋過渡段時「人?車?路」系統的相互作用用拉普拉斯變換法進行了動力響應分析，得到了人的加速度及路面對車的垂直作用力隨時間的變化曲線、人的加速度最大瞬態振動值和路面對車的最大作用力，分析了車輛的行進方向、速度和載重，橋面沉降坡差和搭板長度等車和路各參數對計算結果的影響，並編制了相應的計算程序。分享友人
