This specification discloses a signal transmitting system, a signal receiving system, a signal transmitting method, and an apparatus. In the signal transmitting system provided in this specification, a control chip controls the transmission of a designated signal generated by a signal source to first and second frequency modulation devices. This allows the first and second frequency modulation devices to determine their own useful signals corresponding to the information to be transmitted based on whether they have received the designated signal. They then modulate carrier waves according to their own useful signals to obtain a first radio frequency signal and a second radio frequency signal in the terahertz frequency band, respectively. The transmission of the information to be transmitted is achieved by generating and transmitting coaxially transmitted dual-mode orbital angular momentum electromagnetic waves through metasurface devices. The system can generate and transmit coaxially transmitted dual-mode orbital angular momentum electromagnetic waves in the terahertz frequency band, thus transmitting the information to be transmitted to the signal receiving end.

The application provides carbon nanodots with red anti-Stokes luminescence characteristics and a preparation method and application thereof, relates to the field of carbon nanomaterials, and the carbon nanodots are prepared by using o-phenylenediamine as raw material, mainly have a main emission peak in a red light-near infrared region, and have anti-Stokes emission characteristics in a protic solvent. The anti-Stokes luminescence of the carbon nanodots with red anti-Stokes luminescence characteristics is derived from phonon-assisted single-photon absorption, can be excited by a continuous laser light source, and the anti-Stokes luminescence intensity increases with the increase of temperature. The carbon nanodots with red anti-Stokes luminescence characteristics can be applied to anti-Stokes fluorescence imaging and optoelectronic devices as anti-Stokes imaging reagents.

The application provides a launching device, belonging to the field of projectile launching devices. The launching device comprises a cylinder, a gas pressure cavity is formed in the cylinder; an air inlet hole and an air outlet hole, both of which are formed on the cylinder; a launching tube, which is arranged on the cylinder and is in communication with the gas pressure cavity through the air outlet hole; an opening and closing valve core, which is located in the cylinder and is slidingly installed in the cylinder, the opening and closing valve core opens and closes the air outlet hole, and the sliding direction of the opening and closing valve core is parallel to the axis direction of the launching tube; and an opening and closing assembly, which comprises an unlocking jacking rod, the unlocking jacking rod is slidingly installed in the launching tube, the sliding direction of the unlocking jacking rod is parallel to the axis direction of the launching tube, and the unlocking jacking rod slides and pushes the opening and closing valve core to open the air outlet hole. The opening and closing valve core arranged in the application can make the gas pressure cavity in a sealed state, when the projectile needs to be launched, the unlocking jacking rod is slid and the opening and closing valve core is pushed to open the air outlet hole, and the high-pressure gas in the gas pressure cavity can launch the projectile.
