Provided are a series of polypeptides with antiviral activity. The present invention provides a new strategy for preventing and controlling Enterovirus such as EV71, CVA16, CVA6, CVB3, and CVB5 viruses and provides a new theoretical basis for accelerating the research and development of a polypeptide small molecule drug against Enterovirus such as EV71, CVA16, CVA6, CVB3, and CVB5 viruses.

Broad-spectrum polypeptide against enterovirus and application thereof

A method and a device for synchronous high-speed photographing of microparticle rotation in a liquid cyclone field and for determining the rotation velocity of a microparticle in a liquid cyclone field by using a combination of a synchronous high-speed photographing system and a transparent microparticle containing two centrosymmetrically arranged inner cores having the same diameter. The method comprises: using a transparent microparticle comprising two inner cores having the same diameter and arranged centrosymmetrically as a rotation test particle; acquiring synchronously two groups of two dimensional image series of microparticle motion in a liquid cyclone field using two orthogonally arranged high-speed digital cameras; and reconstructing a three dimensional motion trajectory of the microparticle from the two groups of synchronous image series, and determining a rotation velocity of the microparticle in the cyclone field at the same time.

A magnetic sensor for superconducting quantum interference device using single operational amplifier comprising SQUID, a feedback coil, feedback resistor and an operational amplifier. The voltage signal of SQUID is delivered to one input of the operational amplifier, a bias voltage is delivered to other input of the operational amplifier, and the output of the operational amplifier connects to one end of a feedback resistor, the other end of the feedback resistor connects to a feedback coil that is coupled through mutual inductance with the SQUID so as to generate feedback magnetic flux, the output voltage of the operational amplifier drives the feedback resistance to generate current, thereby forming a flux locking loop. The present invention uses an open loop operational amplifier to implement SQUID magnetic flux locking feedback circuit which simplifies the circuit configuration, decrease the loop delay and thereby achieving higher bandwidth of the flux locking loop.
