As the level of groundwater decreased and filling rate increased, the settlement and settlement after of all three kind of roadbed increased.
The key to gain high yield should choose those varieties with mean filling rate and maximum filling rate to be quick from middle or middle late materials.
These results show that the main causes of poor grain filling are later filling initiation and lower filling rate of inferior grains.
Relationship of heat transfer rate and filling rate is obtained, as well as the relationship of velocity and inner diameter, filling rate.
The rate of average grain filling, the rate of grain filling during gradual increase stage, and the grain filling rate of rapid increase stage had important contribution on increasing grain weight.
The construction of Xiaolangdi rockfill dam is characterized by high standard of flood retaining and control, large quantity of dam filling, short construction period and high filling rate.
Grain filling rate curves of large grain germplasm of rice were right, ordinary one were left.
