The invention discloses a wireless router and a method for acquiring the optimum performance of the wireless router. The wireless router comprises a master control unit, a WIFI module, an Ethernet interface, and a BLE module. When the wireless router operates, the BLE module and a mobile terminal establish connection and the master control unit acquires the direction with the highest signal strength of the mobile terminal by using the BLE module and controls the WIFI antenna of the WIFI module to rotate to the direction with the highest signal strength. The method uses a characteristic that the BLE module and the WIFI module have same frequency (2.4GHz). The direction, acquired by the BLE module, with the highest signal strength of the mobile terminal is also the direction where the mobile terminal may acquire the highest WIFI signal. The WIFI antenna is rotated to the direction so that the wireless router may provide the most powerful WIFI signal for the mobile terminal and a problem of uneven signal strength of the wireless router is overcome. The method is simple and effective, low in design cost, and easy to implement.

A composite system disclosed by the invention forms a polymer / flexible interface layer / inorganic particle three-phase composite system.

The invention relates to a method for preparing iron oxide particles having controllable morphology and size. The method comprises the following steps: 1, adding a surfactant into an organic solvent,fully stirring the surfactant and the organic solvent to obtain a uniformly dispersed suspension, adding an inorganic alkali and a soluble iron salt into the suspension, and fully stirring the inorganic alkali, the soluble iron salt and the suspension until the inorganic alkali and the soluble iron salt are completely dissolved; 2, pouring a solution prepared in step 1 into a closed heating container, and carrying out a thermal reaction; and 3, separating a precipitate in the obtained reaction solution through a centrifuging or magnet process, repeatedly washing the precipitate with ethanol and deionized water, and carrying out vacuum drying to obtain a black solid which is the final product. The accurate and highly-efficient regulation of the size and the morphology of nano-particles is realized through adjusting the proportion of the reaction solvent and the addition amount of the inorganic alkali under same reaction conditions, the size of the obtained particles is 20-400 nm, and solid particles, nano-clusters, triangular prisms, regular octahedrons and other various morphologies can be obtained. The preparation method has the advantages of simplicity, and green and environmentally-friendly raw materials and technology, the product has the advantages of high crystallinity, stable structure, uniform size and gram level reaching yield, and the preparation method is of great guidance significance to preparing magnetic nano-particles.

A highly sensitive ultrasonic probe is provided by effectively damping the ultrasonic wave emitted from a piezoelectric oscillator (1) toward the back surface by means of a backing layer (4) and reducing the reflected wave returning to the piezoelectric oscillator (1) side. The thickness of the backing layer (4) is reduced to a value much smaller than conventional. The ultrasonic probe is provided with a piezoelectric oscillator (1) for generating an ultrasonic wave and a backing layer (4) joined to the back surface of the piezoelectric oscillator (1) and adapted for damping the ultrasonic wave which is emitted toward the back surface of the piezoelectric oscillator (1) and has an opposite phase to the phase of the ultrasonic wave emitted toward the front surface of the piezoelectric oscillator (1). In the backing layer (4), a plurality of sound tubes (5) having different lengths on the basis of the principle of sound wave superposition are arranged in such a way that the longitudinal direction of the sound tubes (5) agrees with the directions in which the ultrasonic waves generated from the piezoelectric oscillator (1) travel toward the front and back surfaces. The sound tubes (5) damp the whole or part of the ultrasonic wave emitted by the piezoelectric oscillator (1) to the backing layer (4) side.

The invention relates to a buoyancy-type liquid level meter for measuring the liquid level by applying a buoyancy, gravity and equilibrant balancing method, aiming at mainly solving the problem of influence of the temperature, pressure, vaporization and coagulation of a measured medium on measurement and overcoming the defects of an existing related measuring instrument. The method is not limited by the situation that the specific gravity of a floater is less than the specific gravity of measured liquid and can be used for measuring the liquid level by using a solid or hollow floater. The measuring meter suitable for multiple environments and multiple liquid levels can be manufactured according to specific conditions. The invention relates to a steam dome water level switch for measuring the steam dome water level inside an industrial boiler.
