- At present,Our country has entried a accelerating period of the urbanization.
- Accelerating noise was measured and analyzed for a passenger car, the inlet air noise of its engine has been found to be the main noise source during the car accelerating period.
- The transient process of zero-sequence current in single-phase reclosure and its effect on the accelerating period of zero-sequence current protection were analyzed.
- The evolution process of landslide could be divided into 4 periods: beginning and accelerating period, quick-moving period, braking period and tamping period.
- In the early stage the amount of C-S-H gel is little,and polymorphic C-S-H started to precipitate in the acceleration period and formed a flower structure.
