Lesson 15-1 Secrecy in industry
工业中的秘密
Two factors weigh heavily against the effectiveness of scientific research in industry. One is the general atmosphere of secrecy in which it is carried out, the other the lack of freedom of the individual research worker. In so far as any inquiry is a secret one, it naturally limits all those engaged in carrying it out from effective contact with their fellow scientists either in other countries or in universities, or even, often enough, in other departments of the same firm. The degree of secrecy naturally varies considerably. Some of the bigger firms are engaged in researches which are of such general and fundamental nature that it is a positive advantage to them not to keep them secret.
有两个因素严重地妨碍工业中科学研究的效率：一是科研工作中普遍存在的保密气氛；二是研究人员缺乏个人自由。任何一项研究都涉及到保密，那些从事科研的人员自然受到了限制。他们不能和其他国家、其他大学、甚至往往不能与本公司的其他部门的同行们进行有效的接触。保密程度自然差别很大。某些大公司进行的研究属于一般和基础的研究，因此不保密对他们才有利。
