A unidirectional or bidirectional sand dispensing device, including a discharge port (), the discharge port includes a lower plate () and an upper plate (), the upper plate is provided above the lower plate, an included angle between a horizontal plane and a straight line where an endpoint of a free end of the upper plate and an endpoint of a free end of the lower plate are located is a leakage angle (), that is to say, a particulate material forms an inclined plane between the upper plate and the lower plate, and an included angle between the inclined plane and the horizontal plane is the leakage angle, which can be adjusted by changing relative positions of the upper plate and the lower plate. The direction of an opening of the sand passing passage is opposite to a moving direction during the sand dispensing operation. When the sand dispensing operation is stopped, the leakage angle is less than or equal to the static repose angle of the particulate material, and is greater than or equal to zero, which ensures that the particulate material will not slide down, and the phenomenon of sand leakage is eliminated. When the sand dispensing operation is being carried out, the leakage angle is greater than or equal to the dynamic repose angle of the particulate material, which ensures that the particulate material will slide down along the inclined plane and that the sand is dispensed relatively uniformly.

Unidirectional or bidirectional sand dispensing device

A computing device receives template files and parameters associated with the template files, where the template files comprise scripts, and where the associated parameters comprise a user preference associated with an efficiency of the image. The computing device may determine dependencies between layers of the scripts based on a unified image model. The unified image model may generate a logic tree that includes nodes, where each one of the nodes represents each one of the layers of the scripts. The computing device may generate an efficient logic tree based on the logic tree and the user preference of a generated image model. The generated image model may generates the efficient logic tree by changing the dependencies of the nodes in the logic tree based on the user preference. Based on the generated efficient logic tree the computing device may build the image.

The present invention discloses a method and apparatus for processing a data packet in a software defined network SDN protocol-based network. The method comprises: receiving a data packet forwarded by a SDN switch in the network; obtaining a rule corresponding to a data flow where the data packet is located; determining, according to the received data packet, data flow characteristics of the data flow where the data packet is located; determining timeout information of the rule according to a predetermined matching relationship between the data flow characteristics and the timeout information, the timeout information indicating time that the rule will be kept in a flow table of the SDN switch; and sending the rule and the timeout information of the rule to the SDN switch for processing the data packet by the SDN switch according to the rule. By means of the method and apparatus of the embodiments of the present invention, the timeout information of the rule may be set flexibly, so that the performance of SDN is boosted efficiently.
