Abstract: A support apparatus for a modal test and a using method thereof. The support apparatus includes: a suspension structure (1) configured to suspend a test unit (2); and a support structure disposed under the suspension structure (1) and configured to support the test unit (2). The suspension structure (1) and the support structure are matched to cause a stiffness of the support apparatus for a modal test to be zero. The support structure includes an anti-stiffness rhombus-shaped frame (4), a scalable sleeve, a horizontal elastic component (49), and a base (6). The scalable sleeve is connected to the anti-stiffness rhombus-shaped frame (4) and the base (6) respectively, and the horizontal elastic component (49) connects two diagonal points of the anti-stiffness rhombus-shaped frame (4).

Abstract: A transverse wave excitation plasma array generator is provided, comprising a plasma array controller and a controlled profile. The plasma array controller includes a plurality of plasma generators, and the plasma array controller is mounted on the controlled profile. The plasma array controller is configured to: control the plurality of plasma generators to generate high-frequency jets under an excitation of high-frequency electricity, obtain spatially distributed high-frequency transverse waves, and generate, based on the high-frequency transverse waves, high-frequency excitation for controlling a second mode of a boundary layer of the controlled profile to promote transition of the boundary layer of the controlled profile, improving a boundary of a frequency domain of plasma flow control. Besides, each of the plurality of plasma generators is connected in series with a plurality of capacitor units and the plurality of inductive coils to form a multi-level array loop.

Abstract: A method and a system for diagnosing high-enthalpy shock tunnel flow field parameters are provided. In the method, the parameters of the reservoir at the end of shock tunnel and nozzle free flow are measured by using a contact measurement technology and a non-contact spectrum measurement technology to diagnose the high-enthalpy shock tunnel flow field. With the method, not only flow field temperature, pressure, component category and component concentration, but also non-equilibrium state information of the flow field and the effective wind tunnel working time can be obtained.

Abstract: Disclosed are a solid-liquid separation anti-soiling toilet, a mounting method and a use. The solid-liquid separation anti-soiling toilet is composed of a processor, a solid container, a liquid reservoir and an exhaust device, where the processor is connected to the solid container, the processor includes a housing, and a clamping device and a drying device which are arranged inside the housing, excreta generated after use of the toilet enters the clamping device of the processor, a liquid in the excreta enters the liquid reservoir after passing through the clamping device, a solid in the excreta is pressed and dried into a sheet inside the clamping device, and enters the solid container, and hot air flow generated by the drying device is used for drying the solid inside the clamping device, and is exhausted outwards through the exhaust device connected to the housing of the processor.

Abstract: The present disclosure relates to an aerothermodynamic environment-friendly toilet, a mounting method, and an application of the aerothermodynamic environment-friendly toilet. The toilet includes a receiver, a processor, a solid storage device, a liquid storage device and a drying device. The toilet is odorless by using an aerothermodynamics principle. When no one uses the toilet, a fan at an exhaust port is used for exhausting a small amount of air from each cavity of the toilet to control an odor source unidirectionally; after use of the toilet, a waste treatment button is triggered, then hot air flow moves downwards, which downwards ejects air at an upper portion of a lower conical port of a reception guider of the receiver.

Abstract: A solid working medium filling device for heat pipe with double process ports includes a working medium tank, an upper cover, an inert gas source and a vacuum molecular pump set. The upper cover is arranged on an upper side of the working medium tank, a process port in the upper cover is in communication with the inert gas source and the vacuum molecular pump set respectively. A heat pipe to be filled includes two process ports, in which a main process port is a vacuumizing port and an inert gas passage port as well as a working medium filling port; and an auxiliary process port is a vacuumizing port as well as a port for inert gas passage. Size of an exhaust passage of the heat pipe and the process tank is doubled, exhausting and vacuumizing are smooth and the filling range can be enlarged as required.
