中文摘要：
探索和测度技术关联度及其引起的发散与收敛，对于深化技术发展的连锁模式，把握技术体系或技术领域的发展和演变的规律具有重要的理论意义与学术价值．以全球太阳能技术领域的专利计量为案例，借助技术共类分析方法，运用平均技术共类伙伴和平均技术共类指数两个指标，分析和测度技术关联度的演变过程，不仅直接显示了太阳能技术在技术发散性和收敛性之间的张力中不断进步的特征，而且定量地表征和揭示了技术关联度的连锁变化所引起的发散性与收敛性两种并行不悖的演变趋势．
英文摘要：
It analyzes and measures the evolution of technology-relatedness by case study on patentometrics of world-wide solar energy technology, using technology co-classification analysis, and employing two indicators called ＂mean technology co-classification partners＂ and ＂mean technology co-classification index＂. Results show that solar energy technology has the characteristics of continuous improvement in the tension between technology convergence and divergence, and has the characteristics of evolving trend in running parallelly between technology convergence and divergence.
