中村修二的H指数小议

诸平

拜读了邢志忠老师的“科研硬指标：火爆的希尔施（h）指数”，看到有人问及中村二修的H-index是多少？因为之前曾经写过“中村修二(Shuji Nakamura)及其高引论著”的博文，今天再来补充一些，也算是对于前文的补充并兼顾回答“中村二修的H-index是多少”的提问。通过网络搜索，关于中村二修的H-index说法不一，从H-index=18到H-index=108不等，这可能与统计源有关，不管怎样，将其一一列出仅供参考。

中村二修的H指数(H=88):Web of Science数据库统计结果

2014年诺贝尔物理学奖其他2位得主的H指数分别是57和62.

H指数（H-index=108）

这是看到的最高值，其详细表述摘引如下：

Shuji Nakamura (Ehime, Japan, 1954), U.S. citizen, is the inventor ofthe LED (Light Emitting Diode) or green light emitting diodes, blue and white.This is a revolutionary high-efficiency light source, long life and much lowerpower consumption than traditional sources such as incandescent bulbs.Considered the future lighting, LEDs have great potential in underdeveloped areas, which is less power. 
Has also developed a UV LED that allows the sterilization of drinking water, which can make a big improvement in living conditions and health of tens of millionsof people in the Third World. Another of hismajor achievements is the blue laser, with important applications inoptoelectronics and data storage. This laser has led to Blu-ray technology by which you can quintuple the amount of data stored on devices like the DVD. He has published 390 articles in scientific journals of high prestige, which have been referenced 18,936 times by his colleagues, resulting in a unique h-index of 108. It also has 448 patents approved or under investigation. 

Scopus数据库统计结果：H-index=91
