Its measurement precision affects directly the quality of products of radiation processing—a light industry in atomic energy industry. Therefore a further study in this field will certainly bring about economical and social benefit.展开更多

Therefore, the amount and distribution of magnetic particles and other harmful dust, such as asbestos and coal, in the Iungs can be estimated by determining the strength of pneumomagnetic fields in the human body, and the ability of self clearance of dust particles from the lungs can be evaluated by the magnetic tracer method. Investigations have shown that pneumomagnetic fields in the human展开更多

Qian urges that such development be based on a broad perspective and with a view towards increasing and improving party leadership in these various social enterprises. In this article he explores the question of the enterprise of the production of spiritual wealth. He points out that a new social science should be created to correspond to economics, which studies the production of material wealth. This new science, dubbed 'culturology,' would study the creation of spiritual wealth. To this end he demonstrates the importance of the enterprise of creating socialist spiritual wealth within the entire process of socialist construction and sets forth the reasons why China must explicitly provide for the establishment of a highlevel socialist spiritual culture while it is establishing a high-level socialist material culture. He points out that culturology would be a science synthetic in nature, and the specialized basic theory of organizing and administering the creation of socialist spiritual wealth could utilize the general theory and methods of systems engineering, adapted to suit each individual field. He also raises a number of problems awaiting study in this enterprise and sketches a rough outline for the development of 'culturology.'展开更多

On absorbing light energy, protons are translocated across the membrane and thereby a proton gradient is generated. The energy stored as proton gradient may be used by the cell for ATP synthesis or other biological energy-requiring functions.展开更多
