Based on this,a vehicle braking force control strategy on low adhesive bent road is proposed,which concurrently considers the maximum lateral force the wheel can take in both wheel lock-up and side slip cases and takes the smaller of two maximum allowable braking forces for both cases as braking force to be applied on vehicle.

The application of modified key-way attachment on semi-fixed bridge;

The energy-equation for steady rapidly varied flow is given herein; with which some problems from the rapidly varied flow can be effectively solved, and then a specific formula is also put forward on the basis of the concept of “additional pressure from bendings” In this way, the streamwise variations of the hydraulic factors such as the water depth, velocity etc.
