摘要
本文着重介绍了世界主要国家和地区 ,为在 2 1世纪生物技术领域的竞争中取得一席之地 ,制定并采取了一系列的有力措施 ;由于各国的重视 ,2 0世纪生物技术的发展成绩喜人 ,并为2
This paper focuses on the policies formulated and adopted by the main countries for winning the contest of the biotechnology.It also introduces the great achievements in the biotechnology in the 20th century,demonstrating the prospect of the 21st century. Key words: Biotechnology; Policy support; Achievementl interpretation. Anested clustering algorithm to decide the partitioning of secondary voltage control areas is studied. This algorithm is based ongraph theory and needs no eigenvalue analysis, hence it has very fast computational speed. Besides, the natural nestingcharacteristic of this method can further speed up the computation. The comparison of this algorithm with the conventionalones proves its validity.
