the effect of inertia weight on particle swarm optimization is studied,on basis of which adopts four kinds of strategies of inertia weight to regulate the speed of a new quantum delta potential well based particle swarm optimization.a faster and more stabile algorithm,found by comparing the performances of four equations regulated the inertia weight,solves 0/1 knapsack problem.the result of experiment shows that the modified algorithm improves the precision of optimal solution and has a faster speed and a higher efficiency in convergence.in a word,choosing a parameter of inertia weight suitably can improve the performance of new qdpso.

摘 要：在研究惯性权重对基本pso算法影响的基础上，根据惯性权重对粒子群算法影响的特点，采用4种惯性权重策略对一种新的具有量子行为的粒子群算法的速度进行调节，比较每种算法的性能，从中找到一种新的性能更好的改进算法，将其用于求解0-1背包问题。实验结果表明较好地选择惯性权重参数对算法的性能有很大提高，该改进算法在求解0-1背包问题中具有高效性，提高了最优解的精度，同时具有较快的收敛速度。

On the basis of briefing the features of deposit products in American banking and the main problems existing in Chinese banking's deposit product design, the paper proposes the following suggestions:(1) quickening the reform of interest rate liberalization to enhance bank's autonomous operation;(2) adding product elements to balance the rights and obligations between depositors and banks;(3)differentiating transaction of funds from bank's service to improve the deposit pricing approache;(4)enriching product catalogues to provide more choices for clients;(5) changing the designing notion that lacks differentiation to pay more attention to market segmentation.

本文在简要介绍美国银行业存款产品设计特点和分析我国银行业存款产品设计存在的主要问题的基础上，提出以下改进存款产品设计的建议：加快利率市场化改革，提高银行经营自主权；增加产品构成要素，平衡双方的权利与义务；区分资金交易和银行服务，改进存款定价方式；增加产品种类，提高客户的可选择性；改变过度平均化的产品设计思想，注重对市场进行细分。

A new convenient synthesis of a series of 1-aryl-2-propanones using aromatic amines as precursors, via diazo reaction and improved Meerwein arylation reaction under mild conditions, was achieved. In addition, 1-[3,5-bisphenyl]-2-propanone is a new compound among the synthesized compounds. This approach is an efficient synthetic method for the aryl-propanones with the different substituting groups.

Cees Hamelink said, at Seminar on Communication Development and the International Programme for the Development on communication in 1984, that as social scientists we are always better at criticizing bad models than at presenting new model. Most of us written extensively and critically about How lerner and Schramm and Rogers have inadequately dealt with all these things, and they have admitted their mistakes themselves, but none of us has really come forward with, a new and better model.
