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。

Entrepreneurs have figured out how to enable and co-opt intermediaries in the supply chain; rather than naively assuming that they serve no purpose and will quietly disappear.

The thesis can be divided into five parts as follows: First, the structural characteristics of finned-pipe evaporator are analyzed. After selecting suitable microelement controller, the heat-transfer and mass-transfer processes are analyzed for every microelement under the conditions of dryness, wetness and frostiness. Based on previous equations, some parameters of frostiness are confirmed and the frost-growing model is set up under frost condition. Some hypotheses are postulated and with the help of the equation of mass-conservation, energy-conservation and momentum-conservation, the evaporation model which fits in the dynamic simulation is built, which set a solid foundation for system simulation. Second, the starting and stopping behaviors under disturbed condition are analyzed and calculated by using the dynamic concentrative parameter model, which gives some advice to better prescribe refrigeration system and set theoretic foundation for carrying out automatic control of refrigeration system. Third, the normal running process is analyzed and calculated by means of rational matching theory, which gives some advice on how to better understand the parameter change under steady state and the affection of inlet-parameter on evaporator. Fourth, the simulation software with dynamic characteristic is designed, which can be applied to calculate thernio-parameter of cryogen, air humidity and frost thickness under different initial and boundary conditions, and to carry out dynamic simulation under conditions of dryness, wetness and frostiness, at the same time, to achieve detection and simulation at any stage from starting to stopping.

If we furthermore assume forconceptual reasons that beliefs of a single epistemological kind are justified, if they areveridical in general, then we can conclude that we have perceptual knowledge about theexternal world, provided we introspectively know of our perceptual beliefs. Hence, our

如果我们为了概念性理由而进一步假设信念是被辩护的，如果它们一般来说都是真实的，那么，我们能够结论：我们拥有关于外在世界的感知知识，只要我们内省地知道我们地感知信念。

大家都知道，网络是虚拟，是不是真正上线欢乐的世界，只有在精神家园冲浪者认为，只有与安心，虽然这一种所谓relaxedness很短，其实也可以采取一个民族的灵魂，喘息空间，以期待为，为疲惫的身体和心理放松的角落，但我并不善于前人类揭示了我的情感上线，其实并不想打下来，从自己一直希望能找到一个讲话的空间，让感性的脉搏摆动随网络虚拟米卸下一切偶然点击出人意料地成为在我心中的故事和情感上的一种捕捉点击然而，从网络到亲爱的朋友会见总是这样的不小心竟然在无意识中心希望与忧虑思上线意欲假设，也是非常决不是真正的关于我的情绪，真的也将抓住将使人出人意料地担心，并相信到一个不会被人理解的人很满足了您我的心飞向上是无法预先知道是什么欢乐的，也许痛苦，但我一直的想法。

At the same time, it produced a series of imaginings that became deeper and deeper – it was like a hypothetical point that allowed me to be completely immersed in the actual cultural background. Various human weaknesses have certain solemn and stirringly dramatic elements. In order to adapt to the basic visual experience, in order to allow the audience to easily accept and enjoy the underlying elements of the work, I intentionally left white spaces, they looked like hints in a guessing game. The viewer who understands would have a good laugh after becoming suddenly enlightened. This enables the viewer and me to have a sort of conspiratorial relationship, its meaning does not reside in the painting itself, but in the shared cultural background of myself and the audience as well as the shared attitude of such a cultural background. This makes it believable, a hidden bridge, often in a somewhat clear yet somewhat mysterious moment, two strangers who have never met are able to achieve a profound understanding, like that happiness of suddenly catching someone when playing hide and seek as a child ...

同时，阐发了一系列的联想，并使之不断地深入，它就像一个假设的点，将我置身于整个现实文化背景之中，这里人的种种缺陷带有某种悲壮成分的戏剧性，为了适应基本的视觉经验，为了使观众一目了然地接受并乐于体味作品中的潜在因素提供某种线索，我留有一些空白，它类似猜谜游戏中的启示，能使会心的观众茅塞顿开后一场哑然失笑，能使我和观众之间形成一种合谋关系，其意义不在画面本身，而在于我和观众之间存有共同的现实文化背景，以及对这种文化背景所持有的共同态度，它也就是有了可信性，就像冥冥中桥梁，常常在时而明晰时而神秘的一瞬，两个素昧平生的陌生人之间突然达到了心领神会的境地，如同儿时捉迷藏游戏中突然捉到对方时的开心……。

For example, we wanted users to be able to be able to change sorts and filters to better understand data they were looking at without leaving the context of the browser. We wanted users to be able to adjust PivotTables to see exactly they data they wanted to see in order to make better business decisions, again without leaving the context of the browser. We wanted users to be able to set parameters to perform what-if analysis, again from within their browser.

Then, a hypothesis of "double force source" for tectonism is put forward, its main points are: the tectonism is not only the result from the action of tectonic stress, but also the result from the action of "double force source", namely, the tectonic stress and subsurface fluid force including force produced by precipitation, etc.

提出了&双力源&构造变动假设，即构造变动不仅是构造应力作用的结果，而且是构造应力与地下流体力共同作用的结果；二者共同作用因方式不同而产生不同的构造变动；在构造变动孕育与产生过程中，构造应力的作用是第一位的，地下流体力则是调制性的，只有那些能与构造应力增强过程产生力学耦合的地下流体力，才能调制与诱发出构造变动异常并促进构造变动。
