The article bases on the traditional graphical method,and applies design principle in the references[1],derives the optimizing design methods which under the condition of meeting the fixed slider stroke and the coefficient of variety of stroke velocity,makes the minimum transmission angle of the eccentric crank slider mechanism to maximum(that is the best transmission angle).

曲柄滑块机构在工程上应用十分广泛，传动角的大小是衡量机构传力性能好坏的一个重要指标。通常求解最佳传动角的方法是建立数学模型，在计算机上进行数值求解，本文在传统图解法的基础上，运用文献[1]中的设计原理，推导出在满足给定的滑块行程S和行程速度变化系数K的条件下，使传动

Being the technological pillar of Guangdong Province in the field of edile fungi. Guangdong Institute of Microbiology has been carrying out lots of researches since 1960's.Beginning from 2000,the key demonstratied project of mushroom industrialization,as a100 projects for science-technology innovation of Guangdong Provience has been under taking by the institute.At present,several industrialized bases and integrated operation pattern of trading company,production base and peasant families has been set up.

项目简介：广东省微生物研究所自上世纪60年代起开展食用菌研究，是广东省食用菌产业的技术支柱。2000年起承担了广东省科技创新百项工程食用菌产业化生产示范项目任务，在清新，丰顺等地指导建立食用菌工厂化基地和公司+基地+农户的经营模式，成功建立了大规模食用菌机械化，规范化生产技术和产业化经营模式，既可工厂化一条龙栽培多种菇类，又可采用基地集中生产菌筒，大批农户分散出菇管理的方式。
