根据“独立自主”的方针和统一适用的要求,改革选矿技术符号是必要的。事实证明,依靠群众,加强领导,许多已惯用多年的旧符号、代号、型号,改起来并不很难。建议有关领导部门抓抓这件事,开展讨论,组织力量,拿出初步方案,及时在全国试行。 According to the principle of “independence and independence” and the requirement of uniform application, it is necessary to reform the dressing symbol. Facts have proved that relying on the masses and strengthening leadership, many old symbols, codes and models that have been used for many years are not difficult to change. It is suggested that the relevant authorities grasp this matter, carry out discussions, organize forces, come up with preliminary plans and try them out in time throughout the country.
