Lesson 15 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.
Yet a great many processes depending on such research are
sought for with complete secrecy until the stage at which patents
can be taken out. Even more processes are never patented at all
but kept as secret processes. This applies particularly to
chemical industries, where chance discoveries play a much
larger part than they do in physical and mechanical industries.
Sometimes the secrecy goes to such an extent that the whole
nature of the research cannot be mentioned. Many firms, for
2 instance, have great difficulty in obtaining technical or scientific
books from libraries because they are unwilling to have their
names entered as having taken out such and such a book for fear
the agents of other firms should be able to trace the kind of
research they are likely to be undertaking. (NCE Book Four)
