我们曾收到某设计研究院的信,相告他们经常去某厂气体站参观学习,得到对方的支持与协助,想表示谢意,“送什么为好呢?”经思考,还是送知识、送技术好,就赠订两份1992年度的《深冷技术》,要我们发行时寄给对方。“知识就是力量”,两份刊物融入深情,钱虽不多,但“智力礼物”可贵。我们也为之感动!值此向赠订者致意! We have received a letter from a design and research institute and told them often to go to a factory gas station to study and get the support and assistance from each other. We would like to express our gratitude. Technology is good, presented two 1992 “cryogenic technology”, we send to each other when issued. “Knowledge is power,” two publications into deep feeling, although not much money, but “intellectual gift” valuable. We are also touched!
