Methods for the selective deposition of materials within a porous substrate. The methods use the passivating effects of masking precursors applied to the porous substrate. A portion of a pore surface within the substrate is masked by exposing the substrate to one or more masking precursors. The depth of the pore surface that is masked is controllable by regulating the exposure of the substrate to the masking precursor. Application of the masking precursor prevents adsorption of one or more subsequently applied metal precursors about a portion of the pore surface coated by the masking precursor. Less than an entirety of the unmasked pore surface is coated by the metal precursor, forming a metal stripe on a portion of the pore surface. The depth of the metal stripe is controllable by regulating exposure of the porous substrate to the metal precursor. Subsequent exposure of the substrate to a saturating water application oxidizes the deposited precursors.

The drug carrying acupuncture needle is excellent in practicability and worth being popularized.

The invention belongs to the technical field of circuit board manufacturing, and specifically relates to a method for preparing a high-precision ultra-thin PCB. The steps include: forming a mask on the surface of a substrate; The pattern of the area and the raised area; the nickel-based metal ion-polyethylene glycol methacrylate resin mixture is injected into the recessed area to form a primer layer; the Cu layer is deposited on the surface of the primer layer and the raised area; it will be located in the raised area The Cu layer and the remaining mask are removed; a flat insulating layer is formed to obtain a high-precision ultra-thin PCB. By adding poly(ethylene glycol methacrylate) resin to form a mixture with nickel-based metal ions, the bonding strength between the primer layer and the substrate is improved, and the Cu layer is deposited on the primer layer, which strengthens the bonding strength between the Cu layer and the primer layer, and finally achieves The bonding strength between the copper line and the base material, there is no problem of short circuit or open circuit caused by the lifting of the copper line, ensuring high-quality transmission of PCB signals.

The invention discloses a method for constructing multi-tree topology and a root node, belonging to the field of network management. The method comprises the steps: confirming the role of the node according to uplink bandwidth information and confirming a subtree that the node belongs to according to the principle that subtree uplink bandwidths are equal or similar; and confirming the position ofthe node in the subtree that the node belongs to according to the uplink bandwidth information of the node. The root node comprises a role confirming module, a subtree attribution confirming module and a position confirming module. During constructing multi-tree topology, the method takes the uplink bandwidth information of the node into consideration and regularly distributes nodes into each subtree according to the uplink bandwidth information of the node, thereby ensuring that the depth of the subtree of the multi-tree topology is easy to control and further being beneficial to improving the transmission efficiency of the multi-tree topology.

The present invention requests protection of an ad hoc network communication method and an ad hoc network communication system. The ad hoc network communication system includes a plurality of wireless nodes for networking, a communication base station, and a cloud server, and a single hop is performed between the wireless nodes. Information transmission, when a wireless node is within the communication radius R of the communication base station, the wireless node within the communication radius R transmits the information wirelessly to the cloud server through the communication base station, and returns the information through the cloud server and transmits the information in the wireless Transmission between nodes to realize self-organizing network communication. The improved destination station number distance vector DSDV protocol is used for networking between the wireless nodes. The main improvement is to combine the traditional destination station number distance vector DSDV protocol to build a multi-tree topology To carry out networking, and the nodes exchange information with their adjacent nodes through the RIP routing information protocol, including the following steps: initialization steps; steps for establishing routes between nodes; priority assignment steps; the higher the transmission priority, the priority selection This route performs data transmission and realizes networking communication.
