Profit model is the strategic issue in the media industry. The dual sales is the core of the media industry.There are some defaults in the profit models such as single, linear and low value-added in the converging trend in the media industry.As the impact of convergence in the media industry appear gradually, the value chain of media industry take on network-based, flexible and similar structure.The innovation of profit model in media industry should focus on value-added, value chain transformation and governance of the value chain management.

内容提要：盈利模式问题是媒介产业发展中的一个战略性问题，二次销售模式作为媒介产业的核心模式在媒介融合的进程中逐渐显露出其单一化、线性化和低增值化的缺陷，由于媒介融合的影响，媒介产业价值链出现网络化、柔性化和同构化的发展趋势，媒介产业在此趋势中应通过价值增值、价值链转换和加强价值链治理实现盈利模式的创新。

The convergence and choice of the step size under the condition of the changeless base set is discussed.

I. d. Bernoulli random variables. First, we can get the upper bound with order from Chebyshev inequality. Second, a better upper bound was gotten with the new inequalities, which can fasten the convergence rate.

并对服从两点分布的独立随机变量X1，X2，…，X进行研究，首先利用Chebyshev不等式得到随机变量偏离方差ES的上界，但它只有阶的收敛速度，然后利用新的不等式得到一个新的上界，它有更快的收敛速度，这在探讨收敛速度时有着重要的理论意义。

Second, On the basis of analysis of density distribution of sequence points on the chaotic orbit of one-dimension chaotic mapping, a mutative interval chaotic optimization algorithm is presented in search for the solution optimums of the non-linear constrained problems with multi-variables and multi-peak values.
