黑菲尔擅长低温真空,他的著作有相当水平,考虑到低温泵潜在的竞争能力,并已公认为真空获得的方向,本书翻译出版有助于推动国内低温真空技术的发展。全书分十章,除第一章概论外,第二章是重点,作者提出有关分子流状态下渐变截面,尤其在有低温面时如何计算真空元件的传输几率,这便
Heffield is good at cryogenic vacuum. He has a considerable amount of his works. Considering the potential competitive advantages of cryogenic pumps and has been acknowledged as the direction to get the vacuum, translation and publication of this book helps to promote the development of cryogenic vacuum technology in China. The book is divided into ten chapters, with the exception of the first chapter introduction, the second chapter is the focus, the author put forward the molecular flow state of the tapered cross section, especially in the low temperature surface, how to calculate the transmission probability of vacuum components, which
