锯材出材率可比指标的测定方法

锯材出材率是说明原木有效利用程度的一个技术经济指标。用同样多的原木生产出更多的锯材,是解决我国工业高速度发展所需原材料的一个重要途径。因此,合理制材,节约利用原木,对促进国民经济的调整与发展具有非常重要的意义。

调整出材率定额,提高锯木制材的经济效果——再谈锯材出材率可比指标的测定方法

锯材出材率定额同其它技术经济定额一样,是组织生产与分配、进行经济核算的基础,是开展社会主义劳动竞赛的评比依据。因此,它必须具有科学性和先进性。只有这样,才能发挥它应有的作用。一根据全国林业系统制材厂际竞赛采用的锯材出材率定额,一九八○年在吉林省林业系统所属十八个制材厂中,有十七个厂超额完成,其中超额最多的单位提高了10.8%,未完成的一个单位也只降低了0.73%。可见,这个定额有些偏低。此外,在各项品种定额之间的平衡关系上,也还存在着一定的问题。主要问题有:

对实行扶持政策促进森林资源枯竭林业局发展的探讨

经过反复学习十一届三中全会以来党中央、国务院对林业颁布的一系列文件和胡耀邦、邓小平等中央领导同志对发展林业的重要指示,感触很深,鼓舞很大。可以说,党和国家对林业的重视已达到了前所未有的程度。当前,全国办林业的高潮已经掀起,这标志着我国林业建设沿着正确方向发展的新转机的到来。很显然。

Recycling of minute metal scraps by semisolid processing:Manufacturing of design materials

As a new attempt to recycle minute metal scraps, the possibility of manufacturing design materials by semisolid extrusion processing was shown.A design material with an intended shape, such as a character or petal shape, was manufactured using minute metal scraps.Similarly, a design material with an intended color pattern for each metal, such as red copper in a white aluminum matrix, resembling grainlike wood, was manufactured by mixing two or more types of minute metal scrap.In addition, secondary design materials, which have engraved patterns on the surface of the target metal made by an electric discharge machine using the above primary design material as an electrode, were manufactured.
