查询词典 completely continuous linear operator

Often, the characterizations of such linear preservers imply that they are algebric isomorphisms or algebric anti-isomorphisms, and therefore reveal the connection between the inherent properties of operator algebras and linear maps on itself. This makes one know and understand operator algebras more deeply.

The ecological socialism and the enviromental economics has partly realize the relation between the institution and resources continuous utilization and resources continuous utilization.The thesis insists that the capitalism leads to the uncontinuous utilization of resources, but the continuous utilization of resources results from the socialist public ownership. Firstly, the common ownership of property right of resources is the base of resources continuous utilization. Because the property right of resources belongs to the society in socialism, the partial interest and integrate interest are untied, as well as the short-term interest and long-term interest, which decides that the socialist owner of resources can抰utilize resources for individual interests like capitalist ones.

本文认为资本主义制度必然导致自然资源非可持续利用，社会主义公有制条件下具有自然资源可持续利用优势：(1)社会主义自然资源产权共有是自然资源可持续利用的客观基础，在社会主义制度之下，由于自然资源产权归全社会所有，局部利益和整体利益是统一的，暂时利益和长远利益是统一的，这就决定了自然资源的所有者不会利用自然资源去谋求不义之利，去损害他人的利益，不会像资本主义制度下满足某部分人的私欲，对自然资源可以统筹利用。

In order to use the existing production conditions sufficiently, by the quality control of the continuous-casting billet and hot sending process and the cooling process after rolling, especially the process controlling of Hot-Continuous-Rolling, realizing the small reduction ratio Hot-Continuous-Rolling production technics to produce big size steel stick upwards Φ 120mm using rectangular continuous-casting billet of 235 X 265mm, the lowest limit of 6.00 used in China currently is broken.
