振幅異常 的英文怎麼說
中文拼音 [zhènfúyìcháng]
振幅異常
英文
amplitude anomaly-
In general, the upward amplitude curve " curvature is larger, and it changes quicker. on the contrary, the downward is smaller and slower ; because the flare force contains the square of the wave elevation velocity, it results in an difference between the flare force frequence and the associated moving frequence ; the flare force decreases the downward amplitude of heaving oscillations ; the speed of ship has an ignorant effect on the peak values of three calculated values, but there is an obvious effect on the oscillating frequence ; the wave amplitude has an effect on the ship motion, and there is an linear relation between the oscillating amplitude and the wave amplitude on the whole. by the way, there are some experiences and lessons according to the progress calculation : before the calculation of the ship motion, we should checkout the balance in a calm water firstly, namely, the whole displace of ship and the longitudinal position of the center of gravity must be consistent with the draft in calm water, or else, the calculation may show the " floating " phenomenon ; the mixed language programming has a lot of virtues, but it exists a fatal limitation - the debug of dll
研究表明：在某些頻率范圍內相關水動力系數基本不隨吃水變化，只有超過某一頻率后水動力系數的值才會出現差異；在橫搖方向，水動力系數並沒有隨著吃水的變化發生規則變化，而是出現了波動現象；近船首剖面的水動力系數計算表明，水動力系數的波動非常大，並遠遠偏離了平均位置的水動力系數值，值的變化速率也不盡相同，總的看來，上振幅曲線曲率較大，變化較快，下振幅曲線曲率較小，變化較慢；外飄力和波面運動的速度的平方項有關，導致其振動頻率和相應運動方向的頻率不同；外飄力使升沉向下運動的幅值減小；船速對三個計算量的峰值影響甚微，但對振動頻率有明顯影響；波幅對船舶運動的影響是明顯的，船舶運動的幅值基本上和波幅成線性關系。Impulse is conducted unusually much if behavioral potential amplitude is reduced with ascendant rate, change by function of film of cardiac muscle cell, should stimulate a gender to drop, the joint between the cell decreases, impulse of as a result is conducted decelerate or block sluggish
沖動傳導異常多由心肌細胞膜性能改變如動作電位振幅和上升速率降低，應激性下降，細胞間接合減少，以致沖動傳導減慢或阻滯。( 3 ) we can detection the azimuth of crack growth by abnormal amplitude or the discrepancy of wave - speed. ( 4 ) we can guess whether crack contains fluids by the change of p - wave speed. second, using pore model, under press and temperature, we have studied the influences of pore density on the characteristic parameters of seismic wave
第一、利用人工裂縫模型，研究了裂縫密度、方位和張開度的變化對地震波屬性參數的影響，根據實驗結果，總結出：可利用橫波分裂的不同程度來檢測裂縫密度的高低；可利用縱橫波的振幅、主頻、衰減（或品質因子q ）和主振幅的變化來檢測裂縫張開度的變化；可利用速度的差異和振幅異常來檢測裂縫發育的方向；可利用縱波速度的變化來推測裂縫中是否含流體。Anomalous reflection amplitudes from fractured reservoirs ? failure of avoa
裂縫油藏的異常反射振幅? ? avoa的失敗？On the basis of the calculating of complexity ( c value ) and combination entropy ( h value ) from the numerical method of geoanomaly analysis, logged signals data ( spontaneous potential, acoustic slowness, spontaneous gamma ray and electrical resistivity ) and seismic data ( amplitude, frequency, phase, etc. ) are processed after regularization of data obtained from linqing basin of shengli oil field. many types of geoanomalies obtained from the computation are analyzed so the spacial variation rules of them can be discovered. then the oil regions can be predicted by this method
本文創新性地將地質異常概念引入油氣勘探領域，以地質異常理論為指導，以勝利油田臨清坳陷油氣地質異常預測研究為例，針對我國陸相含油氣盆地的常規測量、測試和解釋數據，如與地震相關的數據（振幅、頻率、吸收系數、層速度等） 、與測井相關的數據（自然電位、聲波、視電阻率、自然伽馬等）等，提取不同數據類型的地質異常以及異常組合特徵，通過對這些參數的綜合研究分析其空間變化規律，系統地建立有效預測油氣藏的新技術和新方法，進而達到區域油氣資源預測的研究目的。分享友人
