An algorithm for detecting moving IR point target in complex background is proposed,which is based on the Reverse Phase Feature of Neighborhood of target in difference between neighbor frame images that two positions of the target in the difference image are near and the gray value s of them are close to in absolute value but with inverse sign.

基于运动点目标在邻帧差分图像中所具有的近邻反相特征，即运动点目标的两个位置相邻近、灰度值一正一负，提出一种在复杂背景下，基于红外序列图像的运动点目标检测算法。

朱风云 ，秦世引基于运动点目标在邻帧差分图像中所具有的近邻反相特征，即运动点目标的两个位置相邻近、灰度值一正一负，提出一种在复杂背景下，基于红外序列图像的运动点目标检测算法。

As growth rates are near the critical velocity of absolute stability limit by the calculation according to M-S theory, it must be considered that deep cells may keep their cellular structure.

当凝固速度近绝对稳定临界转变点时，KGT模型和Hunt-Lu数值模型与试验结果有较大的差别，其原因是这些模型的计算均未考虑到深胞晶在速度高于MS理论计算的绝对稳定平界面极限后仍能保持自身稳定性而造成的； 8。

A new method based on the Fourier-Bessel series is proposed to calculate the higher-order harmonic components of a nonlinear ultrasound field in absorbing medium and an analytical solution of a series form is obtained. A closed analytical solution of the higher-order harmonics in the zeroth-order Bessel ultrasound field and the focused Gaussian ultrasound field is deduced to study the field property, especially the near-field property.

提出了一种基于Fourier-Bessel级数的新方法，用于计算吸收媒质中非线性超声场的高次谐波分量，得到其级数形式的解析解，由此推导出吸收媒质中零阶Bessel超声场、Gauss聚焦超声场高次谐波的封闭解析解，进而对其声场特性尤其是近场特性进行了研究。

Based on the Volume of Fluid Method, the wave damping absorber of the numerical wave flume for irregular waves has been investigated. Setting the Turbulence motion equation and the Renault equation as the governing equations and using the wall function technique in the near-wall region, an absorbing wave-maker is set at the left side of the flume.

本文对基于VOF方法的不规则波数值波浪水槽进行了阻尼消波研究，以湍流运动方程一雷诺方程为控制方程，在近壁区应用壁函数技术，在数值波浪水槽的左端设置了主动吸收式造波机。

The result showed that the carrier concentration of IMO was less than one third of that of ITO.So,the absorptance of visible light in IMO is lower than in ITO,there might br more space to improve the conductivity of IMO.

因此，IMO薄膜对可见光的吸收小，有很大的发展空间可以通过提高载流子浓度而进一步提高电导率，对近红外线也有较高的透射率，有利于拓展透明导电薄膜的应用领域。

In the solar and near infrared region it is more usual to speak of absorptivity than emissivity.

在日射和近红外区段内，讨论吸收率比讨论发射率更为普遍。

Living in New York for nearly 20 years, he came back to Beijing a couple years ago and began to compose composite works that are complicated and similar to the style of abstract expressionism.

他移居纽约近20年后，近年又回北京，开始创作一种复杂的、接近于抽象表现主义风格的综合材料艺术。

There have been a good number of abstract art of substantial content and varied form in the past twenty years. Abstract art of Shanghai has become an important genre of contemporary art, gaining momentum as it goes, with great variety and new concepts.

近二十年以来，上海举办了多次内容丰富、形式多样的抽象艺术展览，上海抽象艺术业已成为我国的一种重要的当代艺术现象，并出现多元纷呈、观念不断更新的强势劲头。

It can be inferred from the analysis of the two languages that people employ things they are familiar with to refer to abstract concepts, for example, the spatial concepts of UP and DOWN can be used for abstract concepts like NUMBER, STATUS, QUALITY etc.

两种语言中UP，DOWN空间概念的使用是人们遵循"近取诸身，远取诸物"的原则，将空间域的概念投射到数量，社会地位，情绪状态以及好坏等抽象概念域，以减小认知难度的结果。隐喻的使用和理解符合人类认知的普遍规律。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
