| 摘 要： | 在把离子伯恩斯坦波处理成对快阿尔芬波的响应下,导出了点火托卡马克等离子体的离子回旋混合共振的二阶方程.数值求解这个二阶方程得到了快波电场Ey的结构和在共振区快波的转换和反射等.结果与高阶方程的计算很好地一致.计算还得到,只有在弱阻尼的情况下,α粒子吸收的功率才是重要的.

| Abstract: | A novel chaotic communication scheme combining the continuous chaotic system with the digital communication channel is proposed,in which the chaotic modulation and demodulation module are realized with software and the continuous chaotic signals carrying the hidden information are transmitted in digital form.The designing method of the proposed communication scheme is described in detail and the optimal selections of the related parameters to balance the performances of the system in security,transmission rate and transmission quality are discussed.The proposed communication system is easy to practically realize and compared with the conventional digital communication system,the performance of the transmission rate and transmission quality is not lowered while the security of information transmission is obtained. |
