Just one last dance...oh baby..just one last dance we meet in the night in the spanish cafe I look in your eyes just don't know what to say It feels like I'm drowning in salty water Afew hours left'til the sun's gonna rise tomorrow will come an it's time to realize our love has finished forever how I wish to come with you how I wish we made it through Just one last dance before we say goodbye when we sway and turn round and round and round it's like the first time Just one more chance hold me tight and keep me warm cause the night is getting cold and Idon't know where I belong Just one last dance The wine and the lights and the Spanish guitar I'll never forget how romantic they are but I know, tomorrow I'll lose the one I love There's no wayto come wyth you it's the only way to do Just one last dance before we say goodbye when we sway and turn round and round and round it's like the first time Just one more chance hold me tight and keep me warm cause the night is getting cold and Idon't know where I belong Just one last dance

我们来到我们第一次见面的西班牙咖啡馆，看着你的眼睛，我真的不知道要说什么好……明天的太阳还有几个小时就要升起，只有那么短暂的几个小时了，到了明天，我知道，我们之间的爱就会永远、永远的结束……其实我多么希望能够跟你在一起；一辈子都在一起……只有最后的一只舞了，在我们分开之前的，最后的一只，我们像我们第一次见面那样，转啊，转啊……这是最后的一次我们彼此紧紧相依，感受对方的体温，因为夜越来越冷，寒冷到我甚至不知道自己到底属于哪里……最后的一只舞，那摇曳的红酒，那暗昧的灯光，还有那个西班牙吉他，我不会忘记它们有多么的浪漫。但是我知道，明天即将到来，我就会永失我爱……只能这样了，我没有办法跟你厮守……那就跳这最后的舞吧，最后的一只舞，只有这最后的一只舞

The common method, that all strong-correlation terms of the model are eliminated, can bring the loss in the engineering application, so the new method is proposed that the identified model reserves some correlation. The augmented matrix A is constructed by the outputΔW and the matrix S. The"determinating order based on ratio of determinant"is brought out to screen the strong-correlation terms in the structure identification. The latent root estimation is improved in screening the eigenvalues and eigenvectors. Thus the estimation precision is improved greatly.The consistence check of guidance instrument error coefficients of flight test and ground test is the purpose of flight experiment. The causes of inconsistency of the two models are analyzed. The hypothesis test of linear regression model based on F statistics is proposed to check the consistence.Finally, the instability of error coefficients is probably caused by the change of the flight environments, therefore, the relation between the error coefficients and flight environment is analyzed. The approach is presented to identify SINS guidance instrument error models and compensate the error in the segmented sections corresponding to the change of vertical acceleration of aircraft.

在结构辨识中，常用的方法由于将模型中的强相关项全部剔除而给工程应用带来损失，因此，本文提出了新的有益思想，即在保留一定相关性的基础上进行辨识：将输出向量ΔW与环境函数矩阵S构成增广矩阵A，然后采用"比定阶行列式"来剔除相关向量的方法，这样既可以尽可能多地保留了对落点影响大的强相关参数，又可以对落点影响小的强相关参数给予剔除；在参数估计中，改进了特征根估计中特征根和特征向量的筛选方法，提出"近零"准则，从而大大提高了参数估计的精度；再者，鉴于天地模型"一致性"检验是飞行试验和SINS制导工具误差系数分离的主要目的，因此，本文又深入分析了造成天地模型不一致的原因，提出了采用基于F统计的线性回归模型假设检验方法来进行捷联制导工具误差模型的天地"一致性"检验；最后，鉴于飞行环境剧烈变化可能会对惯性仪表误差系数稳定性带来一定的影响，因此本文深入地分析了SINS制导工具误差系数与外界环境的关系，提出了基于过载变化大小的分段辨识和分段实时补偿的算法。

The adaptive program is calculated by T-B stress recovery scheme and z-z error estimation, the error is estimated by energy norm of difference of recovery stress and meshless stress. If the local relative error exceeds the limit relative error, then new nodes will be generated at the high error area.

本研究的自适应方法采用TB应力平滑技术和Z-Z误差估计，利用平滑应力和无网格法所得应力解差值的能量范数来估算误差，如果局部相对误差超过了允许误差，则在高误差域插入新的离散点进行加密。

Besides, we have studied deeply error of two kinds which appeared frequently in the hypothesis testing (error of the first kind and error of the second kind), including the relations to error of two kinds and its effect to the result of hypothesis testing and the effective control of error of two kinds so as to be satisfying and etc.

另外，对假设检验中经常出现的两类错误（第一类错误和第二类错误）也作了深入的探讨，其中涉及到了两类错误之间的关系，两类错误对假设检验结果的影响以及如何有效的控制两类错误使之达到令人满意的程度等。

China and South Korea have excoriated Japan over its approval of new school books which they say whitewash the atrocities committed during Japanese occupation, and anti-Japanese protests have been held in Chinese cities. The lingering bitterness over Japan's past imperialism still threatens to mar relations between the big East Asian powers

中国和韩国强烈谴责日本通过新的中学历史教科书，他们认为这一教科书掩盖了日本在其占领期间所犯下的残酷暴行，反日抗议活动在中国数座城市发生，历史上日本帝国主义制造的痛楚无法被忘却，这有可能破坏东亚强国间的关系。
