Model 2:Model 1 can predicts various indicators of the regional population, but the parameters trends to uncertainty during the long-term, and the cumulative effect of error is significant.

模型一能得到关于各区域人口的各项指标，但在对人口长期趋势进行预测时，模型一中各参数存在较大的不确定性、且误差的累积效应明显，在进行长期预测时达到人口高峰后一直下降，不再有波动，这与实际历史上的三次高峰不符合，故在模型二中挖掘数据内在的相关信息，利用2001-2005年中国国家统计年鉴数据及模型一中短期预测的人口总数建立灰GM(1，1)模型对我国人口总数进行长期预测。

The results show: Firstly, at degree 120, cumulative geoid height error is at the level of 17.616 cm with the adjusted accuracy of center of mass designed as 0 m, and errors come to 18.106 cm, 19.033 cm and 27.329 cm with the adjusted accuracy designed as 5×10-5 m, 1×10-4 m and 5×10-4 m, respectively.

In the Market Equilibrium with Stocks, the necessity for existence of stocks stems from the contradictions of the continuity and discontinuity,the elasticity and inelasticity between supply and demand; stocks's role in a Market Equilibrium with Stocks formation mechanism is largely embodied by a cumulative difference of supply and demand, rather than a simple short-term supply and demand residual error.

在有库存市场均衡中，库存存在的必然性源自于供给与需求在连续性与非连续性、富于弹性与缺乏弹性之间的矛盾；库存在有库存市场均衡形成机制中的作用，更多的表现为一个累积效应下的供求差额，而不是简单的短期供求残差。

Based on equaling the semi-rigid connecting as the reduction of member end section bending stiffness,an optimization equivalent method is put forward on the principal of minimizing the error term between stiffness matrix of fined model and one of equivalent simple model.In this dissertation,structural fatigue cumulative damage and residual life assessment of wind-induced fatigue safety prewarning system is studied.S-N curve method and fracture mechanics method for fatigue analysis are discussed.

本文建立了高耸塔架结构中广泛使用的螺栓节点板联结节点的精细有限元模型，提出了一种优化等效的方法，以刚度矩阵的误差最小为等效原则，在把节点处杆件的半刚性联接等效为杆端截面抗弯刚度下降的基础上，得到了螺栓节点联结杆件的精细有限元模型与简化有限元模型的等效关系。

According to verifying 11 vacuating wells parameters such as structure and sand body thickness that have been predicted by model, it shows high coincidence rate of more than 90% to real datum. Moreover, the permeability variation in pilot site accords with water flooding situation. The computed parameters such as reserves, cumulative oil production of single well and area, water cut have small relative error of less than 2%, the matching accuracy degree is high.

通过11口抽稀井检验，模型预测的构造、砂厚等参数与实际情况相比，符合率在90%以上；试验区的渗透率变化与水淹状况也具有较好的一致性；储量、区块及单井累积产油量、含水等参数计算的相对误差均小于2.0%，拟合精度高。

For example, size problem to offsctdruckereien point of view, the greater the number of celebrity…, the better, because the same set of products can be more, and flexography is not, efficiency depends on the machine speed, in parts of the appropriate size, size 小意 to use low-cost, small size, from roll to die-drum is plate, tape, seihan fees naturally had; size also means that the cumulative operation error gets smaller, quality control is easy.

譬如尺寸问题，以胶印的观点则是开数越大越好，因为同样印数下可以多出产品，而柔版则不然，效率是靠机速实现的，在活件允许的情况下，尺寸适当即可，尺寸小意着使用成本低，试想，尺寸小则从版辊到模切滚筒都小，版材、胶带、制版费自然也就都省了；尺寸小还意味着操作过程中的累计误差变小，质量控制也就容易了。
