Relay wireless sensor network routing method based on energy balance and distance cooperation
InactiveCN101489275AData transmission is stableShorten the timeEnergy efficient ICTNetwork topologiesEnergy balancedInformation data
A wireless sensor network routing method based on energy equalization and distance cooperation relates to data fusion and routing technique of wireless sensor network, and is typically used for clustering routing technique. According to a given regulation, the sensor nodes in the wireless sensor network are divided to cluster head node, relay node and cluster member node. The energy consumption of whole wireless sensor network is fully equalized and the effective usage factor of energy is increased. An energy threshold LT is introduced for realizing the smooth transition of roles between nodes, saving the cluster generation time and reducing the energy consumption. Single-hop communication is adopted in the cluster. Direct sequence spread spectrum is applied. Each cluster uses a unique cluster spreading code. All nodes in the cluster use the unique cluster spreading code for transmitting data to the cluster head and the inter-cluster interference is effectively reduced. The method of the invention can obtain purpose of prolonging the survival time of network under the precondition that the information data is reliably, effectively and accurately transmitted to the base station.

The invention relates to a vertical seam type fishway with bifurcation sections. The vertical seam type fishway with the bifurcation sections comprises a main section and the bifurcation sections enabling the fishway to be bifurcated, wherein the bifurcation sections are parallel with the main section, and the main section and the bifurcation sections are connected through bifurcation pools with horizontal pool bottoms. Each bifurcation pool comprises a main section bifurcation port and a bifurcation section bifurcation port, wherein the main section bifurcation port is parallel with the bifurcation section bifurcation port. A rectification guide plate is further arranged in each bifurcation pool, and gates are arranged in the pools adjacent to the main section bifurcation ports and the bifurcation section bifurcation ports. According to the vertical seam type fishway with the bifurcation sections, the bifurcation sections are arranged at the upstream and the downstream, and the gates of the bifurcation sections are opened and closed properly in the period when the water level is relatively stable, so that fishes can go in and out of the fishway conveniently according to the needs. The rectification guide plate is properly arranged in each bifurcation pool, the water flow structure in each bifurcation pool is obviously improved, and smooth transition from the bifurcation sections to the main section is achieved. The bifurcation pools provide a wide rest space for fishes, have the functions as a rest pool, and help the fishes recover strength in the upstream sailing process.

Fabrication method of microfluidic chip based on nanofiber template method
ActiveCN106925360BWon't hurtRealize precise regulationLaboratory glasswaresElectrospinningSoluble fiber
The invention discloses a micro-fluidic chip manufacturing method based on the nanofiber template method. Firstly, a receiving plate is coated with a photo-curing material layer to form a micro-fluidic chip substrate; secondly, near-field electrospinning or micro liquid spinning is conducted to obtain a first fiber layer with a certain pattern; thirdly, the receiving plate descends by a certain height along with a moving platform, orderly sedimentation of a second fiber layer is conducted, and spinning and curing are conducted layer by layer to obtain a photo-curing model combining orderly fibers with a photo-curing material; fourthly, a last fiber layer is communicated with the surface of the photo-curing model, and when the fibers are completely wrapped by the photo-curing material and certain allowance is reserved, forming of the photo-curing model is completed; fifthly, the photo-curing model is taken out and placed into a solvent, and ultrasonic shaking soluble fibers are added; sixthly, when micro-nanofibers are completely dissolved, the model is taken out to obtain a micro-fluidic chip. The soluble fibers serve as channel filler, and forming precision can reach the precision level same as that of the fiber diameter.
