Design and Implementation of ERP System for Polysilicon Enterprises [PDF]
, 2016 在国内，目前多晶硅行业是近年来高速发展的朝阳行业，因为多晶硅是流程型化工行业，再加上国家政策上的支持，规模化的生产也成为体现企业竞争力的主要因素，因此多晶硅企业的规模不断扩大。在随着市场竞争的不断加大以及多晶企业规模的扩张，企业的管理就存在些漏洞，尤其是多晶硅企业在国内的发展历史不长，起步较晚，生产经营管理不完善，例如多晶硅企业的财务管理、人力资源管理、设备管理、采购库存管理、质量管理、成本管理等方面的管理还不成熟，再加上规模的扩大和人员的增加，目前主要还存在流程管理不完善 ...

SWEET1‐mediated glucose transport is crucial for energy availability in Arabidopsis
New Phytologist, Volume 249, Issue 4, Page 1816-1830, February 2026.Summary The stress‐responsive hormone abscisic acid (ABA) is known for its inhibitory effects on various physiological processes, including seed germination, often resulting in energy deprivation. Interestingly, ABA‐induced germination inhibition can be alleviated by exogenous glucose (Glc), mimicking a functional interplay between ABA and sugar ...
