应读者要求,本刊将定期公布国内主要硅酸盐制品厂(加气制品、各类砌块、陶粒、砖瓦等品种)技术经济指标完成情况,以供行业内交流。这期发表(见表1)的是一些工厂1980年的情况,汇编过程中,得到上海市建材局周一鹏同志的大力协助。 In response to readers’ requests, the publication will periodically publish the completion of technical and economic indicators for major domestic silicate product factories (gas-refining products, various types of blocks, ceramic grains, bricks and tiles, etc.) for exchange within the industry. This period of publication (see Table 1) is the situation of some factories in 1980. During the compilation process, it was strongly assisted by Comrade Zhou Yipeng of Shanghai Municipal Building Material Bureau.
