[交流] 论文摘要翻译

摘要:本文从Mie散射理论出发,利用单次散射理论模型研究了船舰尾流(包括气泡和气泡幕)前向散射穆勒矩阵的分布模式,以及矩阵元与气泡数密度,气泡半径之间的关系。研究表明:(1)单个气泡Mie散射穆勒矩阵元m2和m4在前向90度范围内的存在较大震荡,且震荡幅度随半径增大而增大。(2)气泡幕前向散射穆勒矩阵元M11和M44无方位变化,有方位变化的矩阵元随方位变化具有周期性,各矩阵元随极径增大而指数衰减;矩阵元M11和M44随着气泡半径的增大而增大,随方位角正弦振荡分布的矩阵元振幅随气泡半径增大而增大;矩阵元在气泡数密度为108/m3附近存在极大值,在极值点两侧矩阵元随数密度变化特性相反。

如你是这个方向的学生,应该自己初翻一下。非本专业的人即便英语水平较高,都会面对大量的专业词汇而发憷的。这是提高自己的机会!

中文摘要,和英文初翻,望高人修改

本文从Mie散射理论出发,利用单次散射理论模型研究了船舰尾流(包括气泡和气泡幕)前向散射的穆勒矩阵的分布模式,以及矩阵元与气泡数密度,气泡半径之间的关系。研究表明:单个气泡Mie散射穆勒矩阵元m2和m4在前向90度范围内的存在较大震荡,且震荡幅度随半径增大而增大;气泡幕前向散射穆勒矩阵元M11和M44无方位变化,有方位变化的矩阵元随方位角正弦振荡分布,各矩阵元随极径增大而指数衰减;矩阵元M11和M44随着气泡半径的增大而增大,随方位角正弦振荡分布的矩阵元振幅随气泡半径增大而增大;气泡幕前向散射穆勒矩阵元在气泡数密度为108/m3附近存在极大值,在极值点两侧矩阵元随数密度变化特性相反;对于不同的气泡半径和数密度,矩阵元M12,M13不仅可提供强度大小信息,还可以提供相位反转的信息。


Abstract: Using Single-scattering Theory model,the characteristic distribution pattern of Forward -Scattering Mueller Matrix(FSMM)of ship wakes, and the correlation with bubble number density and bubble radius are discussed based Mie scattering theory . The results indicate that: m2 and m4 elements have relatively strong shocks for a single bubble with scattering angles ranging from 0 to 90 degree, and the amplitude of shocks increases with radius rise; M11 and M44 elements of FSMM for bubbles have no change with different azimuths, the distributions of the elements changing with different azimuths are in accordance with the law of sine shocks ,and the elements of FSMM decay with polar radius exponentially; Elements M11 and M44, together with the amplitudes of the elements changing with different azimuths, increase with radius rise; The maximums of the elements appear when the number density of bubbles is about 108/m3,and the characteristics of elements are opposite with the number densities around the sides ;In addition to the information of intensity, M12 and M13 elements can provide the information of phase reversal while the radius and the number density of bubbles change.

摘要中的结论太多了,这样堆砌感觉不太好。  语法倒是小问题
Using Single-scattering Theory model,the characteristic distribution pattern of Forward -Scattering Mueller Matrix(FSMM)of ship wakes, and the correlations among matrix element, bubble number density and bubble radius are discussed based on Mie scattering theory . The results indicate that: (1) m2 and m4 elements have relatively strong shocks for a single bubble with scattering angles ranging from 0 to 90 degree, and the amplitude of shocks increases with radius; (2) M11 and M44 elements of FSMM for bubbles don’t change with different azimuths, the distributions of the elements changing with different azimuths are in accordance with the law of sine shocks ,and the elements of FSMM decay exponentially with polar radius; (3) Elements M11 and M44, together with the amplitudes of the elements changing with different azimuths, increase with radius; The maximums of the elements appear when the number density of bubbles is about 108/m3,and the changing characteristics of elements are opposite with the number densities around the sides;(4) when the radius and the number density of bubbles change, M12 and M13 elements can provide the information of intensity as well as the information of phase reversal.
