Our study shows that the optical potential of the diffracted light of the semi - gaussian beam is far higher than that of the evanescent - light wave, and its maximum normal velocity of the incident atoms can be far grater than that of the evanescent - light wave under the same parameters, so the blue - detuned semi - gaussian beam, as a novel atomic mirror, can be used to efficiently reflect atoms with a normal velocity of greater than 1 m / s
研究表明，半束蘭失諧高斯光束衍射光場的光學勢遠大於消逝波光場的光學勢，在同樣的參數條件下，入射原子的最大速度也比消逝波光場的大，所以作為一種新穎的原子反射鏡，半束蘭失諧高斯光束可以被用來有效的法向速度大於1m s的入射原子。 -
The thesis analyzes the transmitting characteristic of the uwa channel, derives the propagation losses, eigenrays and channel impulse responses of uwa channel by use of the kraken normal wave mode and the ray trace algorithm based on velocity - depth curvilinear profile approximation. based on the analysis, a scheme of auto - replying lduwarc system by means of spread spectrum technique has been designed
論文首先分析了遠程聲遙控通道傳輸特性，分別利用kraken簡正波和射線跟蹤模型對深海和淺海水聲通道的傳輸特性進行分析，對通道的多徑結構、衰落和環境噪聲進行了計算，並在此基礎上設計了基於擴頻技術的自主應答式遠程聲遙控系統方案。 -
In viewing of the characteristics of propagation of 3d converted wave, studies are performed on the processing methods of 3d converted waves, such as horizontal component rotation, calculation of 3d transition point, hyperbolic velocity analysis and nmo ( normal moveout ) correction of 3d converted wave, and non - hyperbolic velocity ratio analysis and nmo correction of 3d converted wave
基於三維轉換波傳播特點，對三維轉換波資料處理方法進行了研究，包括水平分量旋轉，三維轉換點計算、三維轉換波雙曲速度分析與動校正、三維轉換波非雙曲速度比分析與動校正等。 -
Finally a set of equations with initiate values for boundary value problem is established where the velocity potential and its normal derivative are unknowns. because the model includes the effects of both the time and space to the velocity potential of free surface, it can be applied to strong nonlinear wave. as examples, solitary wave is computed in the numerical flume
推導給出計算域內以所有節點波勢函數和波面位置高度的時間增量為未知量的線性方程組，並同時考慮時間因素和空間變位對波面勢函數的影響，在預設的計算精度下，通過時步內的循環迭代逐一確定每個時步上的波面運動位置，從而建立了一種可適于求解強非線性波浪變形計算的數值模式。 -
The signal testing unit examines directly the production parameter - the belt " s velocity and sends out electrical signal similar to sine wave. the signal handling and analyzing unit disposes of the sensor " s output signal by amplifying, plasticisering a / d transforming and measuring and displays it digitally. after the alarming and controlling unit compares the testing signal with the standard one and analyses, it will show the normal production situation or alarm at the abnormal state and control the related equipments if it is necessary
信號檢測單元直接檢測皮帶速度，並輸出近似正弦波的電信號：信號處理與分析單元對傳感器輸出信號進行放大、整形、 a d轉換和計算等處理，並進行數字顯示；預警、報警、控制單元將信號與標準信號進行比較，經分析后顯示正常狀態或對異常狀態進行聲、光預警、報警。
