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。

I lifted my body and about to go. She held my arm and, pulling thread and niddle she sew the orange skin and made it a latern. She then got a short candle and lighted inside it, handing over it to me: Take it, it is dark and slipery outside and this orange latern may help you find the way.

我站起来要走，她拉住我，一面极其敏捷地拿过穿着麻线的大针，把那小橘碗四周相对地穿起来，像一个小筐似的，用一根小竹棍挑着，又从窗台上拿了一段短短的蜡头，放在里面点起来，递给我说：天黑了，路滑，这盏小橘灯照你上山吧！

结论增隙法操作方便、易于掌握，比较适用于高位、冠部无骨阻力、邻牙阻力小、根部为融合根或根分叉很低等情况下下颌阻生智齿的拔除；劈冠法要求条件高、操作灵活，比较适用于中、低位阻生且发育沟明显、根分叉较高或邻牙阻力较大等情况下下颌阻生智齿的拔除。

N algorithm for close approach determination was developed by Alfano and Negron （1993） based on polynomial splining techniques.

lfano—Negron（1993）提出的空间目标接近分析算法将最小相对距离及其对应时刻和进出误差椭球时刻的求解问题均转化为插值多项式求根问题。A—N算法在判断三次多项式根的存在性、筛选合理实根时存在缺陷，可能导致多余计算。

The Rhizosphere effect of soil bacteria of Artemisia halodendron was the most obvious on shifting sandy land, that of semi- withered Artemisia halodendron was the least on fixed sandy land because it had lost basically physiological active, and the roots had mostly withered.

随着土壤质地的变化流动沙地上差巴嘎蒿根际微生物的根际效应最为明显，而固定沙地濒临死亡的差巴嘎蒿已基本丧失生理活性，根系大部分枯死，根际效应最小。

The other component had a wide distribution range and smaller kurtosis. Root longevity, analyzed by growing-season cohort, was characterized by each of the four theoretical probability distributions: Normal, Welibull, Lognormal, and Exponential.

第一组分的分布峰度较高，寿命较小，且细根均在一个生长季死亡，是细根的主要组成部分；第二个组分的峰度较低，分布平缓，寿命分布范围较大，且细根在两个生长季死亡。

The split between the two groups can hardly be papered over.
