The detailed algorithm on analyzing cracks exploration inside blocks is: enriched approximations which describe singular crack tips fields and discontinuous crack faces are employed under the Partition of Unity theory; the enriched nodes surrounding crack tips or faces are respectively mapped with corresponding enriched degrees of freedom, and the solution of all these degrees of freedom is uniformly proceeded by the implicit iteration algorithm of DDA, then fracture and breakage of DDA blocks can be analyzed. The numeric examples show this algorithm is rational and efficient.

in this paper,the stealthy target′s millimeter wave radiation character is studied.the millimeter wave attenuation induced by sea fog is analyzed.and the detecting capability of the ground-based passive millimeter wave radiometry arrays is discussed.according to one dimension 32 channel 8 mm radiometry arrays detecting stealth target,we have a simulation.the results of the simulation show that it is an efficient way in the thick sea fog condition.

摘 要：研究了空中隐身目标的毫米波辐射特性，分析了浓海雾对毫米波辐射信号的衰减，并对无源毫米波辐射计阵列探测热辐射源的性能进行了分析。在理论建模的基础上针对一维32通道8 mm辐射计阵列探测空中隐身目标进行了仿真实验，结果表明毫米波辐射计阵列在浓海雾气候条件下探测空中隐身目标是一种非常有效的手段。

Complex networks theory is such a result that issue from the observation to relative simple topology structure of networks in different domains. And, recent several years, many research show that many complex systems possess the scale-free property, that is, the mass of nodes have only a few connections but abundant connections are possessed by minority nodes.

复杂网络理论是对不同领域的相对简单的网络拓扑结构进行观测的结果，而且，近几年的研究发现很多复杂系统均拥有无标度特性，即大部分节点只有少数几个连结，而某些节点却拥有与其他节点的大量连结。

According to the research on the displacement in Y direction, shear stress, plastic zone and vector of displacement of tunnel without lining after excavation of the tunnel, the characteristics and failure mechanism of tunnel are summarized in the state of the interface with one side is strong and the other is weak.

通过对开挖后的无衬砌隧道进行竖向位移、剪切应力、塑性区及围岩达到屈服状态时的位移矢量分析研究，总结出结构面两侧岩体上强下弱或下弱上强的状况下，围岩的力学特性和破坏模式；对隧道的选址、支护结构的设计和施工具有广泛的借鉴意义与指导作用。

In the present paper, the induction characteristic of lymphoblastoid, in-terferon in vitro is described. Results indicate that Namalwa cell line possesses a higher interferon-inducing ability than Raji and Yu-Nu cell lines. NDV B1 strain, F strain and Sendai virus can induce more interferon than BB1 virus and poly 1 : C. Priming of pretreating cells with homologous interferon or superinduction did not effect interferon production. The optimal cell concentration for interferon induction is about 106 cells/ml...
