建国以来,水泥工业在基础科学和应用科学的研究中,都取得了许多可喜的成果,其中很多科研成果已经变成生产力。但是,也还有不少科研成果,较长时间没有能够变成生产力,甚至有的在通过技术签定之后,就被束之高阁,这是十分可惜的。根据过去的经验教训,科研成果不能很快变成生产力的原因是多方面的。就水泥工业来说:有的科研课题,并非水泥工业生产建设发展所急需,所以虽然已经取得某些成果,也通过了技术签定,但一时也难以应用到实际中去。这类研究成果,在推广过程中,往往缺乏生命力,即使强行推广,寿命也不会长。如湿法磨机上的弧形筛,过去曾有许多工厂采用,但现在仅有个别工厂坚持使用。这是其中主要原因。有的科研课题,虽是生产、建设所急需的,但成果并不牢靠,经济效益也不显著,或不具备推广条件。这类成果,在推广过程中,往往也是缺乏生命力,既使强行推广,也会夭折。如过去推广过的白灰配料,虽能增产,但 Since the founding of the People’s Republic of China, the cement industry has achieved many gratifying results in the research of basic science and applied science, many of which have become productive forces. However, there are still a lot of scientific research achievements that have not been able to become productive for a long time, and some have even been put on the shelf after being signed by technology. This is a great pity. According to past experiences and lessons, there are many reasons why scientific research cannot quickly become productive. In terms of the cement industry, some scientific research topics are not urgently needed for the development of the cement industry. Therefore, although some achievements have been achieved and the technology has been signed, it is difficult to apply them to the actual situation. In the promotion process, such research results often lack vitality. Even if they are forcibly promoted, their life span will not be long. For example, arc screens on wet mills have been used in many factories in the past, but only a few factories have insisted on using them. This is the main reason. Some scientific research topics are urgently needed for production and construction, but the results are not reliable, the economic benefits are not significant, or there are no promotion conditions. In the promotion process, such achievements often lack vitality, even if they are forcibly promoted, they will also die. For example, white ash ingredients promoted in the past can increase production, but
