对军队有形资产的研究中，选取了6种常用的评价方法，包括AHP、Gini-Style法、专家咨询法、统计学描述性分析法、DEA、标准测量法；而在军队无形资产评估中使用了重置成本法、市场法以及收益现值法等。

Previous solutions to these problems, such as topology conversion methods and forward-pointed arcs methods, not only have deficiencies of having high temporal and spatial complicacies, but also have shortcomings for the topological data difficult to be formed and be renewed in good time. This paper comes up with an Arc Topology Algorithm to solve one-way road prohibitions and turn penalties problems, and puts forth Azimuth Algorithm and Turn-angle Algorithm to solve nodal weight problem.

针对以往的解决方案如转换网络法和扩展的前向关联边法计算的时间复杂度和空间复杂度高以及拓扑数据难以建立和难以实时更新的缺陷，论文构造了弧段拓扑法以解决单向行驶限制和转向限制问题，构造了方位角法和转向角法以解决节点权重问题。

While naturalists take the idea that human—made law possesses the just disposition of natural law as an argument to champion city—state law strongly,tragedians find conflicts between positive law and natural law,thereby enduing natural law with moral connotation for the first time.

正当自然主义者以人定法具有自然法的正义秉性为据大力捍卫城邦法律之时，悲剧作家则发现了人定法与自然法的冲突，从而第一次赋予自然法以道德的内涵。

In this paper,NBR was modified by fluorinating with XeF2 and the reaction kinetics of fluorination was studied by FT-IR spectrometry.The apparent reaction order of 1.5 was suggested,which seemed to become less for long reaction time.

目前报道的高分子表面氟化改性的方法很多，主要的方式有：辐射接枝法、等离子体活化法[1，2]、静电喷涂法、离子注入法及氟化剂表面化学反应法[3—7]等。

A commutation error is then considered in addition to the conventional residual error to generate the innovative residual error. Such an error is applied into cost functions to derive finite impulse response and infinite impulse response filter-based adaptive algorithms for ANC applications, referred to as FxRLS/CE and FuRLS/FRE+CE algorithms, respectively. Convergence analyses based on Lyapunov stability criteria for time-varying discrete-time systems can be carried out for the FxLMS/CE, FxRLS/CE and FuRLS/ FRE+CE algorithms to ensure stability. Computer simulations and experiments demonstrate that the innovative residual error-based adaptive algorithms can free the restriction of the slow-adaptation assumption in the conventional ANC approaches.
