Abstract: A silicone rubber with UV aging resistance and low water absorption and its preparation method and application are provided. The preparation method uses a coupling agent KH570 and glyceryl monostearate to perform modified treatment on titanium dioxide to obtain modified titanium dioxide, uses a surface-modified coupling agent A171 and glyceryl monostearate to perform modified treatment on fumed silica to obtain modified fumed silica, and further performs subsequent treatment on methyl vinyl siloxane raw rubber, silicone oil, aluminum hydroxide, the modified fumed silica, the modified titanium dioxide, zinc oxide, ?-alumina, a coupling agent KH560, a defoamer, iron oxide and a vulcanizing agent to obtain the silicone rubber. The silicone rubber prepared by the preparation method has low water absorption and excellent aging resistance, and its mechanical and electrical properties are also superior.

Abstract: A dual-polarization radar is disclosed. Selected embodiments provide a radar structure having a single receiving channel and enabling alternate transmission and simultaneous reception. Selected embodiments use a first polarization direction antenna and a second polarization direction antenna to transmit and receive a first polarization direction echo signal and a second polarization direction echo signal. The first polarization direction echo signal and the second polarization direction echo signal are received and synthesized by a synthesis module, which transmits the synthesized signal as the backscattered echo signal to a receiving module.

Abstract: The present disclosure provides a tidal simulation test device and a method of use thereof. The tidal simulation test device includes a water supply pool, a water level adjustment pool, a subtidal zone simulation pool, an intertidal zone simulation pool, a supratidal zone simulation pool and a two-way water flow adjustment control box. The two-way water flow adjustment control box is provided therein with an electromagnetic flow control meter, a forward frequency conversion self-priming pump, a reverse frequency conversion self-priming pump and an intelligent time-controlled three-way controller. In the method, the start and stop of the forward frequency conversion self-priming pump and the reverse frequency conversion self-priming pump are controlled through an intelligent switch, and a water flow is adjusted through the electromagnetic flow control meter, thereby realizing periodic changes in a water level to simulate different types of tides and coastal wetlands.
