    摘要:

    应用三角形一个重要的基本不等式,证明了有关三角形内角平分线之和的一个猜想不等式:设wa,wb,wc与s分别是三角形三条内角平分线和半周长,R,r分别为三角形的外接圆半径,则(wa+wb+wc)2s2+102Rr/5+66r2/5.指出了一个相关的值得进一步探讨的问题.

    Abstract:

    China and India are both countries of glorious civilizations with a history of thousands of years.They achieved glorious success in mathematics between 1000 BC-1000 AD.Many of their achievements were made several hundred years or even one thousand years earlier than in Europe.However,after the 12th century, due to alien invasions,mathematical research in India declined abruptly.Similarly,during the 14th century,China's mathematical studies reached a stagnation point right after a research climax was started.Having been constantly invaded by other nations in modern times,after years of endeavor,the two countries gained vitality in research on mathematics and entered a new era at the middle of 1900s.From an overall perspective,both are at the same level in this field with their own strong points.But both still keep a long distance to the international level.Currently,the two nations are striving on innovation and creation in mathematical science,expecting to build up a solid foundation for their ongoing rapid economic development.
