減斜-
According to statistics parameters of the typical clouds over xi ' an region and cloud data obtained from the global distribution of cloud cover under the auspices of world meteorological organization, for xi ' an region typical cloud, the parameters of khragian - mazin cloud drop size distribution are obtained. based on xi ' an cloud water content profile, on earth - space paths, attenuation due to cloud are calculated by means of the k - m distribution. it is shown that the attenuation induced by cloud are taken into account at ka - at elevation angle smaller than 30 and v - band paths
第三，根據西安地區氣象觀測數據，討論了西安典型雲的宏觀和微觀物理特性；根據西安典型雲的觀測結果和世界氣象組織提供的數據，得到西安典型雲的k - m雲滴譜參數；並根據西安地區雲的液水含量，計算了地一空路徑上雲的衰減，結果表明，在v波段和仰角小於30度的ka波段路徑，雲的衰減需加以考慮。 -
Mortars are high - angle weapons that are relatively short range and can safely be used to drop rounds close to friendly forces ( when in the defense, a mortar can hit targets as close as 70 - 100 meters away from the gun position with ease )
迫擊炮是高射角武器，射程相對較短，可以為友軍提供安全的近距離支援（在防禦戰中，一門迫擊炮可以輕而易舉地打擊距離炮身70 ? 100米的目標） 。 -
The preferences are analyzed, pipe ’ s parameters such as depth, thickness, pipe diameter, and mechanical property of material ; soil parameters such as soil types, internal friction angle, pipe - soil interaction ; fault ’ s parameters such as fault types, fault throw, fault drop, fault - pipe angle, mechanical property of material ; load types such as gravity force, linear displacement load, seismic load and seismic wave. some conclusions are drawn from the calculating results : when buried pipes cross fault, pipe ’ s embedded depth should be shallow, and big pipe diameter and thick wall should be selected. avoid the site where fault moves severe, and select suitable pipe - fault angle
在有限元三維模型建立中考慮的因素有:管道自身參數如管道埋置深度、管壁厚度、管徑、管道材料等;巖土材料參數如土體類型、巖土的內摩擦角、管土相互作用等;斷層考慮有斷層類型，斷層斷距，斷層錯動距離，斷層與管道的交角，斷層材料的考慮等;荷載分別考慮靜荷載，動荷載，其中動荷載包括線性位移加載、地震力加載和地震波加載等。 -
But the influence trend of the maximum rolling angle and the rolling period was not so simple, it was because the influence of which embodied in the phase relationship of mass flow and the pressure drop across the tube. the d - partition method was developed to separate the test tube into four regions and the drift flow model was imported into the two phase region, based on which the solution of the response of the pressure drop of tested tube to the inlet mass flow perturbation can be obtained
在不搖擺和搖擺工況下，採用d分區法對實驗段進行分區，在兩相區採用漂移流模型對實驗段的壓降對入口流速擾動的響應進行了求解，給出了各區壓降響應的表達式，進而得到了在不搖擺和搖擺工況下，壓降與入口流速擾動之間的傳遞函數。 -
Besides, the effect on the performance caused by a variety of water drop types and contents is discussed. a model for computing the loss and deviation angle is developed using stage - stacking method on average streamline
著重分析了含有不同類型以及不同含量的水滴的來流對風扇壓氣機特性的影響，並且將計算結果與風扇壓氣機在來流為空氣下的特性進行對比分析。 -
The spin, sometimes called the negative spin, occurs when the angle of attack of the canopy is increased and one side is stalled causing it to drop almost vertically and spin on its yaw axis
旋轉，有時候叫反向旋轉，發生於當傘的攻角增加，而且單側失速時，引起幾乎垂直地下墜，同時繞著它的偏移軸心旋轉。 -
In city, because the occupied area of the urban sewage pumping station is usually limited, the length of the forebay is inclined to be short and the diffusion angle in flow direction is big accordingly, which causes bad flow pattern, such as backflows, vortices, etc. the bad flow pattern will make the efficiency of the pump unit drop
城市排污泵站由於條件的限制，前池一般面積較小，擴散角較大，擴散段較短，因此水流進入前池后突然擴散，流態紊亂，易行成迴流、漩渦等不良水流流態，從而影響水泵的工作性能。
