This thesis mainly discuss following issues, Theory and simple expressions for array covariance matrixes are derived when angular spread functions are symmetric distribution functions, i. e. the Uniform distribution, the Gauss distribution, the Laplace distribution and the Von Mises distribution, and a non-symmetric distribution function, i. e. the Gamma distribution. And the relation between the effective signal subspace and the array number, or and the nominal angle of the distributed source, the angular spread, the distributed functions, and the Signal-to-Noise Ratio is gained. The dimension of the effective signal subspace increases with increment of the array number. And it is more obvious to the non-symmetric distribution. The dimension of the effective signal subspace decreases with increment of the nominal angle. And the distributed source is equal to a point source as θ=π/2. The dimension of the effective signal subspace increases with increment of the angular spread.

本论文针对阵列信号处理中广泛存在的分布源现象，主要讨论了以下问题：推导了角度分布函数分别为对称的均匀分布、高斯分布、拉普拉斯分布、Von Mises分布和非对称的伽马分布时，分布源阵列接收信号协方差阵的严格模型和简化模型，得到了单个分布源的有效信号子空间随阵元数、分布源中心角、分布角、角度分布函数和信噪比的变化规律：随着阵元数的增加，对所有角度分布函数的有效信号子空间维数也随着增加，且非对称分布函数的有效信号子空间充满整个空间的可能性更大；随着分布源中心角逐步增加，有效信号子空间维数逐步减小，当θ=π/2时，等价于点源情形；随着分布源分布角逐渐加大，有效信号子空间维数也随之增加，直到有效信号子空间充满整个空间；随着信噪比的增加，有效信号子空间维数有一定程度的减少。

The confidentiality of the existing rules and regulations to conduct a comprehensive clean-up, failed to meet the job requirements of confidentiality under the new situation, the timely amendment, supplement; right not included in the management of classified computers within the LAN, it is necessary to develop practical management systems into effective Monitoring scope; the establishment of classified removable storage media, a registration system for the device model, hardware number, custodian, enable time registered in the books, and report to the offices of record; the establishment of classified computers, classified removable storage media to go out the registration ledger system; non-classified computer connected to the Internet is strictly prohibited non-classified computer and between computers with classified national security department without the approval of the removable storage media to transfer data directly; classified obsolete computers and removable storage media must be submitted to Council Committee for the record confidentiality, rosters later physical methods for destruction.

对现有的保密规章制度进行一次全面清理，对不适应新形势下保密工作要求的，及时进行修订、补充；对未纳入局域网内管理的涉密计算机，要制定切实可行的管理制度，纳入有效监控范围；建立涉密移动存储介质登记制度，将设备型号、硬件编号、保管人、启用时间等登记在册，并报局办公室备案；建立涉密计算机、涉密移动存储介质外出登记台账制度；严禁涉密计算机接入互联网，严禁非涉密计算机与涉密计算机之间用未经国家保密部门认可的移动存储介质直接传输数据；涉密计算机及移动存储介质报废，须报局保密委备案，登记造册后用物理方法进行销毁。

However, measuring p27 in the blood at ages 1 and 6 weeks old by ELISA could be used for discriminating the ALV-J-infected flocks from non-infective flocks having endogenous non-tumorigenic avian leucosis. Because the p27 of the former increases but that of the latter decreases during young ages.

然而应用ALV-J可在1周龄内鸡群中迅速传播的特性，感染鸡群早期的p27会上升，因此检测1周龄及6周龄鸡只血液p27的升高，可以与无ALV-J感染只含内源性病毒的鸡群区别。

In the meantime music and dance are dynamic state arts with the human body perform for intermediate, which have two kinds of cultural characteristic of language writing and non- language literalness and the non-language writing characteristic be theirs main aspect, which make race music and dance of protection and lineage have more difficulties comparing cultural heritage ancient works and cultural object ruins .

同时，音乐和舞蹈是以人体表演为中介的动态艺术，它具有语言文字与非语言文字的两种文化特征，非语言文字特征是它的主要方面，这就使得民族音乐和舞蹈的保护与传承较文献典籍和文物遗址而言有更大的难度。

Methods The differentially expressed genes between liver tumor and non-tumor tissue were cloned by using suppression subtractive hybridization. Differentially expressed genes were sequenced and analized for homology in Gene Bank. In situ hybridization was performed to identify special expression of differentially expressed genes in livre tumor and non-tumor tissues.

方法通过抑制消减杂交法克隆土拨鼠HBV引发的肝癌组织和非癌组织中差异表达的基因；对差异表达基因进行DNA序列测定后于Gene Bank内分析其同源性；应用原位杂交确定差异基因在肝癌组织和非癌组织中的特异性表达。

Sub-articles 24 and 26 of UCP 500 allow for two scenarios:(1) where the transport document (non-negotiable sea waybill or multimodal transport document) bears a pre-printed wording to the effect that the goods have been loaded on board (the question relates to sea shipments) or similar, then this date is deemed to be the date of shipment (the emphasis being ''pre-printed'' and not by an addition at a later time); and (2) where the transport document (non-negotiable sea waybill or multimodal transport document) bears a pre-printed wording to the effect that the goods have been ''received for shipment'' or similar, then the document should bear a separate notation showing the date the goods were shipped on board.

"UCP500的第24条款项和第26条款项允许有两种情形：（1）如果运输单据（不可转让海运单或多式运输单据）带有预先印就的货物已装船词语（这个问题与海洋运输有关）或类似词语，该日期将被认为是装运日期（这里强调的是"预先印就"而不是后来增加的内容）；（2）如果运输单据（不可转让海运单或多式运输单据）带有预先印就的货物已经"收妥待运或类似词语，那么单据应当带有一个表明货物装船日期的单独的批注。
