渐变折射率2

说明：  根据舰船螺旋桨噪声一书给出的计算空泡噪声的公式，简便计算各种条件下的螺旋桨噪声级的程序(According to the formula for calculating the cavitation noise given in the book "Propeller Noise of Ships", the program for calculating the propeller noise level under various conditions is simple and convenient.)

扩展卡尔曼滤波算法，应用很多，换个背景就可应用，有点基础就下载，本程序已删掉背景。(Extended Kalman filter algorithm, the application of a lot can change in the context of applications, a little foundation on the download, the procedures have been deleted from the background.)

说明：  对abaqus有限元程序进行二次开发的J积分运算(J-integral operation of ABAQUS finite element program)

说明：  Fourier Ptychography是一种首先开发用于显微镜的成像技术。该技术首先收集感兴趣的显微样品的一系列图像。从相干光源（通常从LED阵列）以不同的照明角度获取每个图像。然后，使用迭代相位检索算法将获取的图像集组合为最终的高分辨率图像，该图像可以包含多达十亿个像素（千兆像素）。该技术还提供了非干涉相位图像和近波长衍射极限分辨率。(Fourier Ptychography is an imaging technique first developed for use in microscopes. The technique first collects a series of images of a microscopic sample of interest. Each image is acquired under a different angle of illumination from a coherent light source (typically from an array of LEDs). The acquired image set is then combined using an iterative phase retrieval algorithm into a final high-resolution image that can contain up to a billion pixels (a gigapixel). The technique also provides a non-interferometric phase image and near wavelength diffraction-limited resolution.)
