Generally, tidal bore is wave alignment moving upstream estuary, and its surface will break when the wave alignment is strong, which leads to water roll tracing the source. the velocity, which is between small - disturbed wave velocities before tidal bore happens and the one after tidal bore happens, increases with the ratio of tidal bore height to the water depth in wave front
涌潮一般是向河口上游推進的波列，強度大時，表面破碎，進而發展成溯源推進的水滾，其傳播速度隨涌潮高度與波前水深比值增加，大小介於涌潮前後小擾動波波速之間。 -
This paper applies ittc single - parameter ocean wave spectrum to simulate a random long - crested ocean wave according to statistics superposition theory and real - time simulate disturbance on the ship by random wave. it simulates roll and pitch of the ship in random wave in the time domain and gains roll angle ( t ) and pitch angle ( t ) signal of ship rolling movement
本文根據統計疊加理論，採用ittc單參數標準海浪譜模擬模擬實際的長峰波隨機海浪，進而實時模擬長峰波隨機海浪對船舶的隨機擾動，對船舶在海浪中的橫搖和縱搖運動進行了時域模擬，得到船舶搖蕩運動的橫搖角信號（ t ）和縱搖角信號（ t ） 。 -

頸部揉捏按摩頭，通過正反二個方向的旋轉按摩，腰、背部設有四輪行走機構，兩寬、兩窄滾動的按摩輪，能緊貼您的腰背部，根據腰背曲線作上下行走按摩，靠墊兩端設有遠紅外線墊波系統，能使熱波紅外線深入人體細胞深層護理，坐墊大腿部設有兩捶擊頭可選擇敲擊、振顫、拍打三種按摩手法，小腿墊設一可調速滾輪機構。 -
By analyzing the result, three most main factors influencing the calculation accuracy are found : the constitution of wave scatter diagram, interpolating the irregular wave and the estimating of roll damping coefficient
通過分析計算結果提出了影響計算精度的三個最主要的因素：海浪能量譜的構成、不規則波的合成方法、橫搖阻尼的估算。 -
By using band and equal distance wavelet transform and average energy method, the ground roll wave can be recognized and suppressed belier, hence obtaining good results
採用窄檔等頻距小波變換方法，在含面波的低頻頻帶內，用平均能量法識別和壓制面波，取得良好效果。 -
Ground roll wave has characteristics of strong energy, low frequency and slow attenuation
摘要面波具有能量強、頻率低、吸收衰減緩慢等特點。 -
In the low band of wavelet transform, energy of ground roll wave is normally greater than the average energy in overall band of seismic reflection event, which is regarded as the discrimination criterion for it
在小波分頻后的含面波頻帶內，同一時刻較強面波能量總要比該時刻全排列的平均能量大得多，這是分頻識別強面波的判別準則。 -
With the disturbance of random wave the ship will inevitably roll and result in the ship ' s incline, especially, for small ships which the most obliquity of the ship is likely to reach above degree 15. in the actual combat the rolling movement of the ship will result in difficult control of the artillery for the artillerymen on the ship, reduce the artillery ' s probability of shots, and affect the power of the artillery by direct control of the object ( artillery ) fixed on the ship it can be kept horizontal state all the time
尤其是對大量的小型艦船，船體的最大傾角甚至可達到15以上。在實戰中，船舶的搖蕩將造成炮手對船載火炮的操縱性能降低，降低火炮的發射命中率，影響到船載火炮威力的發揮。通過直接控制固連于船體的火炮，使其始終保持在水平狀態，可以提高實戰中火炮的操縱性能，提高火炮的命中率。
