The experimental results show that for most continuous optimization problems, the strategy of concave function gains an advantage over the linear strategy, while the linear strategy outperforms strategy of convex function with the identical initial and final weights.

试验结果表明，对于多数连续优化问题，在初始权值和最终权值相同的情况下，凹函数递减策略优于线性策略，而线性策略优于凸函数策略，凹函数递减策略能够在不影响收敛精度的情况下较大幅度地提高粒子群算法的收敛速度。

If the Landweber method and pre-iteration method were convergent, the residue sequence would be monotone decreasing. By analyzing the convergence, the fact is demonstrated that for the severe ill-conditioned matrix of sensitivity coefficient, because of the limitation of the precision of the computer, the residue sequence is not monotone decreasing; thereby the reconstruction images diverge from the true distribution of the conductivity. So the generalized inverse method with threshold is established and the selection way of the regularization parameter is presented, by which the better images are reconstructed.

Landweber法和预迭代法收敛，则其残差序列单调递减，通过对它们的收敛性进行分析，证实对于病态性严重的灵敏度系数矩阵，由于受计算精度的限制，迭代过程中的残差序列不再单调递减，从而导致重建图象偏离实际电导率分布，因此作者建立了带阈值的广义逆算法，提出了规则化参数选择方法，获得了较好的图象重建质量。

The accumulation factors of heavy metal in different kinds of leafy vegetables decreased with the increase of the extractable heavy metal concentration, which can be described best by the exponential equation y=ax(superscript b.

不同品种蔬菜对各重金属的富集系数随可提取态重金属含量增加呈幂函数形式递减，且递减趋势与土壤中可提取态重金属含量范围密切相关。

In spite of the limited air sounding data, we would use the adiabatic lapse rate method and the time interpolation to get the hourly mixing height. It should be noticed that the degree of accuracy was not so good enough that we can completely believe it. As a result, the follow research worker should notice this over estimation by the method.

因此尽管在有限的例行气象探空观测下，采用乾绝热递减法配合时间权重内插计算是现有条件下的一权宜方法，但是须注意的是，此方法的准确性并不如我们所预期，混合层比对的相关性也不甚理想，因此建议后续研究，如有继续采用乾绝热递减法来决定混合层高度之时，应多加留意探空资料对混合层所产生的高估影响。

This paper points out that Keynes macroeconomic theory is on the basis of three major psychological law: reduced marginal propensity to consume, liquidity preference, decreased marginal efficiency of capital.

本文指出，凯恩斯的宏观经济理论以先验的三大心理规律，即边际消费倾向递减、流动性偏好、资本边际效率递减为基础，脱离资本主义深层次的经济关系和经济结构，来分析资本主义的宏观经济运行。

The great tour purchasing power is the drive power of promoting the region's tourism developmentln the regional space, scale economic and regional separation are one of the basic characteristics of promoting tourism industry, So we must arrange the regional tourism industry with a systematic method and give prominence to the central city. For its outstanding area in the regional space, central city has evident superiority in the regional ecnomic development, and has echelon between central city and its periphery scennic spots, which is the inducement mechanism of tourism industry's arranging, developing and advancing step by step. For the law of diminishing marginal utility and the theory of equilibrium, the max utility equilibrium of tourism consumption be at the point of tangency of undiscrepancy curve and the cost budget curve.

中心城市居民巨大的出游力是拉动其周边旅游地发展重要的内在驱动力；由于地缘关系，区域规模经济与地域分割并存，是旅游产业运动的一个基本特征，为此必须对区域旅游经济进行系统化布局，突出中心城市的产业中心性；因其区位条件独特，中心城市在区域经济发展中居于明显的优势，与周边城乡部位存在经济发展上的梯次性，这种梯次性是区域旅游生产力布局、产业发展梯次传动，最终整体联动的经济诱导机制；根据边际效用递减规律和旅游者最大效用均衡理论，旅游消费效用最大化的均衡在无差异曲线与开支预算线的切点(即旅游目的地选择的最佳位置)上，且随着边际效用递减，目的地选择的最佳位置向远离中心城市方向移动，这就是中心城市与周边旅游地互动关系的经济学解释。

由于产量递减主要是油相相对渗透率下降造成的，因此文中提出一种利用相对渗透率预测产量递减规律的新方法。
