简介:实现国有企业三年改革与脱困的奋斗目标,需要加快培养和造就一大批能够跨世纪担负领导重任的中青年干部。如果沿用传统的机制,也可能选拔和培养一些优秀的年轻干部,但要满足经济形势发展的迫切需要,使优秀年轻人才脱颖而出,成批涌现,是不可能的。因而必须对传统机制进行改造,重塑干部管理与培养机制。传统机制的主要缺陷在哪里?概括起来就是:用人渠道难以拓宽,人才配置难以优化,能上能下难以操作,论资排辈难以打破,考核鉴别难以把握,培训提高不重实效。社会主义市场经济作为一种开放的、竞争的经济,它要求干部管理与培养工作从根本上摆脱计划经济的羁绊,摒弃封闭保守的思维和管理方式,从经济发展战略的整体角度筹划干部人才工作,与市场经济同频共振,从根本上适应市场经济的特有属性,大批量、高质量、快速度选拔和培养一批跨世纪的年青干部,最终形成人尽其才、才尽其用、人才辈出的局面。

简介:烧结料在混合过程中需加水润湿并制粒,以改善混合料透气性,增加通过料层的风量,达到提高烧结矿产、质量的目的。混合料水分的准确检测和自动控制是烧结工艺中不可缺少的环节,烧结料水分的相对稳定对烧结过程的顺利进行以及实现烧结生产优质、低耗至关重要,烧结工作者为此做了大量的工作,其中引进北京宇宏泰测控技术公司开发研制的MM710-2lCS水分测量控制系统就是一次有益的尝试。
