Methods. A 60-year-old man with athetoid cerebral palsy and a history of posterior occipitocerical fusion presented with quadriparesis. Salage surgery for cerical myelopathy and pseudarthrosis was performed with laminectomy and rearthrodesis using the pedicle screw system. An intraspinal cyst was identified as the main cause of the paraparesis.

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。

Objective It was reported that rALR (rat augmenter of liver regeneration) distribute in most of tissue and organ of rat, no-tissue specility; mRNA expression of rALR was identified variedly in different tissue, strongest in testis. But nowadays there was not some study on ALR in rat testis. Here to confirm the expression and localization of ALR in infancy,adult and old rat testis,comparing the change of ALR expression degree before per 70 PH and after per 70 PH. In order to evaluate expression principle of ALR in rat testis and know if ALR has tight connection with spermatogenesis and development of testis, to explore the relation between ALR and reproduction, to discover the possible expression character and functional methods of ALR.

目的：文献报道rALR分布于各组织器官，无组织特异性，但其mRNA在各组织的表达强度有差异，在睾丸组织表达最强，目前对大鼠睾丸ALR表达尚无深入的研究；本实验研究不同年龄段大鼠睾丸组织中肝再生增强因子的表达水平、表达部位、以及表达的方式，进而探讨睾丸ALR与睾丸发育、精子生成以及生殖活动的关系；同时探究睾丸组织ALR表达是否参与了肝脏的再生过程中，进一步了解睾丸ALR表达的特性及作用方式。
