Recognizing its importance is only the fist step to advocate invetion or innovation， and some effective measures should be taken for it. For one thing， our authority should continue to enlarge the recruit of graduate. For another， the conditions of scientists and skilled workers should be further improved. Only in this way， can “the soul of our nation” be fully embodied and our nation have a brighter future.

This file contains a C++Builder 4 project called SimplyChaos-X ver 3.1 (SCX31). SCX31 is an encryption tool. I designed it as my graduation paper work. SCX31 is a symmetric stream cipher built on chaos function, one time pad cipher and inspiration from Ground Effect (aviation). The key length can be up to 40 characters (320 bits).

JLAB is a set of Matlab functions I have written or co-written over the past fifteen years for the purpose of analyzing data. It consists of four hundred m-files spanning thirty thousand lines of code. JLAB includes functions ranging in complexity from one-line aliases to high-level algorithms for certain specialized tasks. These have been collected together and made publicly available for you to use, modify, and --- subject to certain very reasonable constraints --- to redistribute. Some of the highlights are: a suite of functions for the rapid manipulation of multi-component, potentially multi-dimensional datasets a systematic way of dealing with datasets having components of non-uniform length tools for fine-tuning figures using compact, straightforward statements and specialized functions for spectral and time / frequency analysis, including advanced wavelet algorithms developed by myself and collaborators.

用fpga实现的DA转换器，有说明和源码，VDHL文件。 A PLD Based Delta-Sigma DAC Delta-Sigma modulation is the simple, yet powerful, technique responsible for the extraordinary performance and low cost of today s audio CD players. The simplest Delta-Sigma DAC consists of a Delta-Sigma modulator and a one bit DAC. Since, both of these components can be realized using digital circuits, it is possible to implement a low precision Delta-Sigma DAC using a PLD.

linux下用C语言写的聊天程序！/*BUG and NOTE: Not join protect to Shared Memory Segments,example Semaphore Arrays. Not check the parameters validity. When transmit may be error. If the client program no right exit,others cannot know,the service program shouldbe check the client program whether exist timing. The program when exit(), it do not delete the Shared Memory Segments,you maybe use atexit() but the program have some processes. When one process is exit(),others is continue. The service program s action is few. And so on. */
