The inquiry learning of modern Chinese should emphasize the study way of the probing into type voluntarily , stress the application of knowledge, teach students how to utilize many kinds of methods , obtain information through the multiple channel, pay attention to the learning process, improve students' thinking level , train students to pinpoint the problems and solve the ability of the problem.
The improved attack can recover the main key by about 2120 encryption operations and 2123 bytes of memory. Compared with Gilbert-Minier's attack,the time complexity of this attack decreases 224 times with 28 times increase in memory.
By means of the powerful calculation and simulation functions of MATLAB, this paper introduced a way to design and realize the system simulation teaching software based on the graphic user interface (GUI) of MATLAB. The software makes convenience for the teaching and studying, simplifies the teaching and improves the study efficiency.
At the same time , the powerful optimization function of Matlab simplifies calculation process and improves calculation efficiency.
The results proved that MS could induce apoptosis of tumor cells, result in typical apoptosis changes in vitro ,influence transforming process of tumor cells from phase S to phase G2M and enhance the positive marking percentage of breaking point of DNA.
