A study on Coping style of Chinese Stock Investors

Objective:To study the coping style of Chinese stock investors.Methods:Coping Style Questionnaire was sent to 1840 stock investors. Results: Solving-problem and Retreat were often used; the coping style was significantly different among investors of different investing time, investing cycle, profit and loss,and self-evaluation on stock knowledge. Investors of different time of investing were significantly different in the coping skill of seeking help and rationalization.Negative coping ways were more adopted by the investors of long investing cycle,and loss or no profit or loss. Conclusion:We need pay attention to investors' mental health, especially to the long-time invest and investor of loss; it will improve the investers' ability to cope with setbacks when we help them to master more stock knowledge

采用改进的PIC技术的OCDMA系统性能分析

文章提出改进的并行干扰消除（PIC）技术来减少多址干扰对光码分多址（OCDMA）系统性能的影响。以光正交码（OOC）为地址码,推导出改进的PIC技术的系统误码率表达式。通过仿真分析给出了误码率与OOC的码长、码重和并发用户数的关系。结果表明,采用改进的PIC技术,能大大降低OCDMA系统的误码率,改善系统性能,且系统满足误码率≤10-9时所需的最小OOC码长远远小于PIC所需的最小OOC码长

色散管理孤子系统中调制不稳定性的研究

文章从色散管理孤子（DMS）在光纤中传输满足的非线性薛定谔方程出发,推导出DMS系统中调制不稳定性（MI）增益谱的表达式,并给出了数值模拟结果。结果表明:色散管理图强度越强,对MI过程产生的增益的抑制作用越大;路径平均色散越大,抑制MI过程产生的增益越明显
