可构造的

In fact, the multiplicity is caused by the reason that there are a lot of techniques to fractionalize the eigenvalues of Fourier transform in the procedure of constructing the fractional Fourier transform.

实际上，分数傅立叶变换的多样性主要是由傅立叶变换的特征值在构造分数傅立叶变换时可采取不同的分数化方法所决定的。

The concept of harmonic control between two systems is presented. Necessary and sufficient conditions are given for harmonical stabilization of two systems. These results can be generalized to harmonic stability problems for more than two systems. Examples are given to illustrate the results.

摘要提出了两个系统协调控制的概念，主要研究了不同系统间的互助合作问题，给出两个系统间可协调稳定的充要条件及构造协调控制律的算法，并举例说明了所给结果的有效性，这些结果都可以向多系统协调稳定问题推广。

提出了两个系统协调控制的概念，主要研究了不同系统间的互助合作问题，给出两个系统间可协调稳定的充要条件及构造协调控制律的算法，并举例说明了所给结果的有效性，这些结果都可以向多系统协调稳定问题推广。

Taking Taiwania cryptomerioides as an example, as estimation, the preservation treated sill of one wooden construction building with a floor area of 136 m2 could reduce 43.72 kg CO2 which fixed in the wood would return to the atmosphere by the gnawing of termite. And it would reduce 129.90 kg and 123.50 kg of CO2 caused by the infringement of Lenzites betulina and Laetiporus sulphureus respectively.

CO2减量效益方面，建筑物若加以适当的木材防腐后，以台湾杉试材经AAC防腐，所改善的试材重量损失率为例，一栋面积为136 m2木质构造建筑物之地槛材部分，可减少因台湾家白蚁啃蚀造成木材中固定的CO2约43.72 kg返还大气；抵抗白腐菌及褐腐菌侵害而言，减少129.90及123.50 kg的CO2返还大气。

The variational equations are established for holonomic nonconservative dynamical systems in the high-dimensional ex-tended phase space.

建立了高维增广相空间中完整非保守力学系统的变分方程，并利用系统的正则方程和变分方程证明，可由第一积分直接构造系统的积分不变量，并举例说明结果的应用。

Aiming at the actual need of impeach work, and on the basis of analyzing, concluding, summarizing and informing against the systematic current situation at present, the article structure the new model of electronic impeaching system, adopt group signature and bit commitment technology to realize each functions of the system respectively, and guarantee the security of accuser, such as anonymity, unforgeability, undeniable, unlinkability,traceability,etc.

论文针对检举工作的实际需要，在分析、归纳、总结了当前检举系统现状的基础上，构造了新型电子检举系统的模型，并分别采用群签名和比特承诺技术实现了系统的各项功能，保证了匿名性、不可伪造性、不可否认性、不相关性和可追踪性等安全性。

ABSTRACT The application of hypermedia systems, especially the boom in World Wide Web make us have cognizance of such a fact that hypermedia would be the most potential tools to construct the global distributed information base environment.

超媒体的应用，尤其是WWW的繁荣揭示超媒体将是构造全球化大规模分布信息基础环境时极具潜力的工具：可将超媒体引入到尽可能多的应用及现有计算环。。。

It also shows that,for"reasonable"Hermite data,the "good" couple of PH cubics can be directly constructed,obviating the need to compute and compare all four solutions.

对于&合理&的Hermite数据，本文还给出了不需计算和比较所有的四个解便可直接构造&好&的三次PH曲线偶的方法。

It is shown that the harmonic spectrum is extended to in the case of the combined fields, and an isolated 63 as pulse can be obtained by superposing around the cut-off position of the high-order harmonic generation spectrum.

研究结果表明，氦原子在这种组合场驱动下，高次谐波谱的平台区域能得到很大的扩展，其截止位置可延伸到，通过构造截止位置附近的高次谐波谱能够得到脉宽为63 as的单个阿秒脉冲。

Wall-rock metasomatism, boilings and separation of fluid facies, as well as mixture with meteoric water were the main evolution processes in a fluid system. The activiti es of ore-bearing fractures can be divided into two states: brittle and brittle -ductile ones.

与围岩的交代作用，沸腾作用引起的相分离和大气降水的加入所产生的混合稀释是成矿流体体系演化的主要途径，容矿断裂构造活动可划分为脆性破裂和韧脆性扩张两种动力学状态。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.
