利用miracl大数库，利用椭圆曲线快速实现算法ANF计算椭圆曲线上的单标量乘法

C++实现MPEG话音帧头数据读取与时间长度估计.这个文章和程序针对的是包含XING和VBRI头的MPEG audio帧进行读取，然后根据它们估算声音的长度。这里不包括任何的话音audio数据的编码与解码。不过，文章确实对audio frame header进行了非常详细的说明。-C++ Achieve MPEG audio header data read with the estimated length of time. This article and procedures aimed at containing XING and VBRI head read MPEG audio frame, and then according to their estimates of the length of the sound. Here does not include any voice audio data encoding and decoding. However, the article on the audio frame header is indeed a very detailed explanation.

这是一个抽道程序，用于时间抽道，把时间抽稀，在画图上可以较快的画出图像，并且合理的抽道可以保证图像并不失真。非常简单实用的一个程序，本人原创代码，希望大家喜欢。

用vc实现的一个画图程序，画一个圆形和方形。本来可以画三角形，不过没有设定。同时程序中设了timer用来使图形移动，加一点趣味罢了！-vc achieved with a drawing, and painting a circle and a square. Triangle could have been painted, but not set. While proceedings timer used to set up a mobile so that the graphics and some fun too!
