The Golgi methods currently available have disadvantages such as low successful rate, production of precipitate or involving complex procedures. 现存很多高尔基染色法有成功率低、产生沉淀或操作程序复杂等缺点。
The adjustable recirculating ratio process flow has the advantages of high fluid yield, low coke rate of production, flexible operation and strong adaptability. 结果表明,可调循环比工艺流程液收高,焦碳产率低,操作灵活,适应性强。
MBR has a lot of advantages, such as high volumetric load, high concentration sludge, the low rate of sludge production, operation and management convenient, auto-control etc.. 它具有容积负荷大、污泥浓度高、污泥产率低、操作管理方便、易于实现自动控制等优点。
Layering is the currently practiced propagation method which has a low propagation coefficient. Cuttings and grafting have low rate of seedling production. The excellent seedlings are in serious shortage in the face of the rapid development of hazelnut industrialization. 榛子目前主要采用压条繁殖,繁殖系数低,扦插、嫁接成苗率低,面对榛子产业化迅速发展的需求,榛子良种优良无性系的苗木较少。
