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。

At and , we can get a univariate cubic equation in and its three roots . By the dependence of the roots and the coefficients of the equation, we can choose corresponding space points ( such that the distance is the shortest from to the point with parameters and . Thereby we can get all the data of discrete points on the cubic curve of blending surface at . Again we denote the maximum value and minimum value of planar parameter with which meets by and respectively.

利用根与系数的连续相依性，可以选相应的空间点使其距离的圆截线上对应值的点最近的两个根，从而得到处拼接曲面的截线的离散点的数据并确定出与相截的平面参数的最大最小值类似地由处拼接曲面截线的离散数据得到处的离散数据，这样可以依次计算出拼接曲面上对应所有参数点的离散点的坐标。

The result showed that twocDNA fragments which expressed at high level both in shoot and radicle representedthe gene encoding beta-D-glucosidase; one cDNA fragment expressed specifically inshoot represented the gene encoding mitochondria HSP60; most clones of MF12 andMF17 fragments respectively represented the chloroplast genes encoding prp22 andprp19 proteins which are two components of ribosomal small subunit; while thededuced amino acid sequence from each exceptional one clone was respectivelyhomologous to CDC5 proteins and vesicle-associated membrane proteins; otherthree cDNA fragments expressed preferentially in shoot had no homologue inGenBank.

结果发现2个在胚芽和胚根中表达量都很高的cDNA片段代表的是编码玉米β-D-葡糖苷酶的基因；一个在胚芽中表达而在胚根中不表达的片段代表的是编码线粒体分子伴侣HSP60的基因；片段MFl2的大部分克隆测序结果是与叶绿体基因组中编码核糖体小亚基蛋白prp22的基因同源，但其中有一个克隆测定的cDNA片段序列推测的氨基酸序列与CDC5家族成员有较高的同源性；片段MF17的大部分克隆测序结果与叶绿体基因组中编码核糖体蛋白prp19的基因同源，而有一克隆测定的cDNA片段序列推测的氨基酸序列与参与信号转导的膜结合蛋白VAP27和VAMP有较高的同源性；另有3个优先在胚芽中表达的cDNA片段未查询到同源序列。

As the English language is constructed from root words, while common prefixes and suffixes are added to the root word to change the meaning. The trick is syllabication, a technique which allows students to separate words into small units which facilitates pronunciation along with phonics — an understanding of sound units. This course allows students to increase their vocabulary, retain vocabulary, and improve their spelling. Syllabications identify, root word building blocks/ divide words for pronunciation….

因为英文是源于根单词结构的语言，当常用的前缀和后缀的加在根单词上，字意就产生了变化，窍门是划分音节---一种能够让学生把单词划分为小的单位，使看字读音及发音更容易的方法，一种对声音单位的理解，本课帮助学生提高他们的词汇量，保持词汇量，提高他们的拼读，划分音节，词根单词积木组合，为发音而划分单词

Their common structure and annual changing pattern of mycorhizae are as follows: Fungi infect and form endomycorrhizal structure with plants throughout the latter's grown period, and hyphae exist in the cortical cells of roots in the following four forms: Coffee-colored or yellow big peloton consisting of twisted hyphae; Dust-colored or yellow big peloton consisting of fragmentary hyphae; Colorless scattered hyphae; Orange or yellow small peloton with blurry hyphae.

接著我们往下，进入反应炉中非常热的水，在最底部有个怪物，当我们看到时，他四根指头上的皮肤，以及他那非常动物的外星头在脱皮，最后我们看到五根手指，很像人类的生物，非常小，有个大头，大眼睛，看起来非常像史考利在第三季一开始，在采矿场看到的人形。

IT IS an oft-told story, but it does not get any less horrific on repetition. Fifteen years ago, a paedophile enticed seven-year-old Megan Kanka into his home in New Jersey by offering to show her a puppy. He then raped her, killed her and dumped her body in a nearby park.
