文献[1]是一篇参加国际会议的文章,由第二作者在会上宣读。当时,我们只准备在会议上透露一信息:我们已可建立可压缩非线性位流方程的边界元解法。对方法的中心思想无意细说,拟在此项研究工作结束后再正式发表专文系统叙述。所以文献[1]写得比较简单显得晦涩。现仅就文献[2]和文献[3]对文献[1]所提的问题作如下补充说明,我们今后发表的正式文章中对此将作更全面的论述。 Reference [1] is an article to attend an international conference, which was read out by the second author. At that time, we were only going to reveal a message at a conference: We could have established a boundary element solution to a compressible nonlinear flow equation. The central idea of ​​the method is not intended to be elaborated, and it is proposed that an article system be formally published after this research is finished. Therefore, the literature [1] is relatively simple and appears obscure. The problems raised by reference [1] are now only supplemented by references [2] and [3], which we will discuss in more detail in our official essays to be published in the future.
