J and the work density pfaffian δW areIt follows that the n. and s. condition for J to be path-independent is that in simply connected region:      服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 刘叔仪 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1977/V13/Iz1/46 No related articles found!
