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 examination falls into two parts: the written test and the operation test. The written test is to check one's basic electric knowledge, which includes electric control theories, installation standards, etc. The operation test is a bit difficulty. Firstly, you have to connect several major loops and control loops appointed by the examiner within limited time. If you do right, the electricity is connected, the bell rings and the light turns on, then you will pass the test; but if it explodes and emits smoke, then you will not only get zero score but be scolded. Life is not a game, and one should never pretend to know things that he does not know.

考试分笔试和操作二项，笔试的内容都是最基本的电工知识，电气控制原理，电气安装规范等等，而考操作就有难度了，首先要你在规定的时间里接好考官指定几的主回路和控制回路，接对了，通上电，灯亮铃响顺利过关；若是爆炸冒烟，那不仅没分还要挨骂，生命不可儿戏，不懂不能装懂。

To update test technical system and build informatized test range, we discuss the establishment of informatized test technical system for naval military equipment, present an idea of multi-sensor information fusing based on network environment, and propose a concept for realizing the unidirectional transparentness of the test using multi-dimensional sensing systems, and establish a dynamic equation of the "quantized" equipment test system.

The new launch schedule will enable us to complete the expansion of our internet-based testing operations worldwide.until the revised general test is launched, ets will continue to deliver the gre general test using the current network of secure, proctored test centers. pearlman notes that the graduate community has relied on the general test for 57 years and that ets is committed to continuing to deliver valid and reliable scores with both the current and revised general test.

首先，从去年关于新版gre内容方面的变革以及明年gre考试将采用网考形式的情况来看，gre改革的科学性进一步提高，同时此次新gre改革推迟并采用网考形式还得到了美国各大教育机构的认可；第二，gre考试的推迟为中国考生争取了更多的时间；第三，采用网考的形式也意味着新gre考试将有可能增加考点范围或是增加考试次数。
