误差模型

Based on the finite strain theory, a subroutine‐UEL for ABAQUS is developed , and the residual pore pressure under wave load is computed, and stability of soil around pipeline and seabed is analyzed. Regarding the liquefaction soil as model, a subroutine‐UMAT for ABAQUS is developed , and the behavior of pipeline in liquefaction soil analysis qualitatively.

并据此模型对复杂波浪荷载下埋置管线的动力响应进行分析，发现波浪的非线性和随机性以及管线-土体之间的接触效应对计算结果的影响十分显著，如果忽略这些因素，则会在分析埋置管线动力响应时造成较大误差。4。

These conditions do not relate to the unknown parameters but the dimension of model, so it is easy to apply in practice. Next, we consider the relative efficiency of LSE against the beast linear unbiased estimator.

我们给出了Pitman准则下，最小二乘估计优于Within估计的一个充分条件，最后又得到了广义均方误差意义下两步估计一致的优于Between估计和Within估计的充分条件，并且这些条件只是和模型维数有关而和未知参数无关的一些不等式关系，因此便于实际应用。

The paper analyzes the dynamic relations of the China's real estate price index and main macroeconomic indexes in recent years under the cointegration and error correction model frame. The finding is that real estate price has the support of macroeconomic background, real estate market risk is not severe.

从此角度出发，本文在协整和误差校正模型的框架下，分析了中国近年来房地产价格指数与主要宏观经济指标的长期均衡关系，得出了虽然近年来房地产价格上涨较快，但从总体上看，其变化有宏观经济背景的支持，房地产市场风险还不是很大的结论。

According to this method, all the undetermined parameters can be determined without fitting them to experimental data.

用这种模型计算旋流器的迁移率不需用实验数据拟合待定参数，避免了实验误差的影响。

As a result of error distribution\\\'s non-uniqueness, draws out to the standard deviation understanding again, by about standard deviation reflected that the erroneous zero rank value two side the variation targets, the application unimodal distribution fits the error distribution, the goal is: By approaches the rationality which under the enhancement goodness of fit\\\'s premise determines to the error.

从文章的上下文感觉此标准值似乎是人为规定的，并不受实测数据本身分布的影响，不具有客观性。个人认为：研究在实际中实测数据相对于均值的分布更有意义。按照作者的观点，误差的分布都是单峰的，除了正态分布这种对称分布外，作者认为还有不对称的偏峰分布。因此研究这种偏峰分布模型可能更有意义。

There is very little information for general cell diagnosis, which is universal problem in aluminum reduction process. Studies on technique of getting and processing cell state parameters have been made, where direct detection, on-line emulation and fuzzy information processing are combined. Then a new method of dynamic temperature detection, it's model and formula are proposed, and a practical equipment was designed. 3. Information about aluminum reduction process state are very different, not enough and unprecise, while there are many knowledge based on experience.

2为解决目前铝电解过程控制系统中普遍存在的、能用于槽况综合解析的信息不足这一问题，研究了综合运用直接检测技术、在线仿真技术和模糊信息处理技术等技术获取和处理电解槽的各种状态参数和信息的方法；并提出了一种新型的动态测温方法，推导了该方法的数学模型和计算公式，给出了公式的误差分析并设计了一个实验用动态测温装置，向实现对电解质温度的直接检测和控制迈出了探索性的一步。

The model errors or uncertainties and disturbances in manipulation make the position errors unpreventable.

而机械手模型的不确定因素和外界的扰动又使这种位置误差不可避免。

As for determination of upper bound of error, a primarymethod was suggested from the viewpoint of safety of flood control.

对模型中的误差上限确定问题，从防洪安全的角度给出了初步确定方法。

A conservative form for the flow equation is established by using upwind finite volume element method.

考察非饱和水流问题的模型方程，利用线性迎风有限体积元方法建立非饱和流动的守恒形式，并获得该方法形式为O的误差估计，最后给出数值模拟。

This paper brings in three variates including energy consumption, energy price and economic growth on the basis of previous double variate system. Using the data from 1978 to 2004, we do Cointegration Test to see the long relationship among them. Then we build an Error Correcting Model. Moreover, we use Granger Causality Test to re-examine the relationship of the three.

本文在前人简单双变量系统的基础上构建了能源消费，能源价格与经济增长三变量系统，利用1978-2004年的数据，通过协整分析，检验了能源消费，能源价格，经济增长之间的关系，构造了三变量的误差修正模型，并用Granger因果检验进一步验证了三变量之间的关系。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
