Therefore it is the duty of all who consider themselves anticapitalist, like the NPA in France, all who call themselves revolutionary socialists, communists, Leninists and Trotskyists, to combine forces and to convene a conference of their organisations. Such a conference must discuss an action programme for coordinating our defensive struggles, transforming them into a revolutionary counter-attack against imperialism and capitalism.

因此，把力量集合起来并且召开一个他们组织的会议是所有自认为反资本主义者的义务，像法国的"新反资本主义党"，所有成员都称自己为社会主义者，共产主义者，列宁主义者，托派……像这样的一个会议必须讨论一个行动计划，这个行动计划是关于协调我们的防御性斗争，并将其转为对帝国主义和资本主义的革命反击。

Then, a fast algorithm for the product of the permutation factor circulant matrix is given. Finally, The least-square solutions of inverse problems and the optimal approximation problems for the permutation factor circulant matrix are discussed.

Ringrose began to study nest algebras in the 1960s, many people have devoted themselves to the study of non-selfadjoint and reflexive operator algebras including nest algebras, commutative subspace lattice algebras, completely distributive subspace lattice algebras and so on, and obtain a lot of beautiful achievements.

自从60年代J.Ringrose开始研究套代数以来，人们对套代数、交换子空间格代数和完全分配子空间格代数等非自伴自反算子代数进行了深入研究，并且取得了大量出色的研究成果。

Nest algebra is an important class of non-selfadjoint reflexive operator algebras, which is the natural generalization of upper triangular matrix algebra in infinite dimensional space.

中文摘要：套代数是一类重要的非自伴、自反算子代数，它是上三角矩阵代数在无穷维空间上的自然推广。

Three elements should be calculated in first-order circuit, which can synthesise analytical solution. Second-order series RLC and parallel RLC both can be calculated by the general function, which uses the Matlab to calculate differential equations. Generally, second-order and high-order circuits use Laplace transformation to formulate circuit equation, and get analytical solution by using Laplace inverse transform.

一阶电路先计算3要素，后合成解析结果；RLC串联和并联的二阶电路采用自编的通用函数计算，自编函数采用了Matlab求解微分方程的符号运算方法；一般的二阶电路和高阶电路采用拉氏变换列写电路方程，再用拉氏反变换得到解析结果。
