Abstract: The present invention relates to a groundwater circulation well system with pressure-adjustable hydrodynamic cavitation, including a circulation well body, a sucked and injected water circulation assembly and a hydrodynamic cavitator. The sucked and injected water circulation assembly is based on a water suction and injection pump. The hydrodynamic cavitator is provided, inside a vortex chamber, with a vortex water inlet column capable of changing a water passing aperture. The hydrodynamic cavitator is capable of changing a bubbling pressure and a breaking pressure of hydrodynamic cavitation bubbles in the vortex water inlet column. The hydrodynamic cavitator generates vortices in the circulation well body to accelerate uniform mixing of a remediation agent and the groundwater. Energy from collapsing and bursting of the hydrodynamic cavitation bubbles activates the remediation agent such that contaminants in the groundwater are efficiently degraded.

Abstract: The present application belongs to a technical field of modifying natural polymer materials, provides a high-viscosity lithium carboxymethyl cellulose and preparation method therefor and application thereof. Raw materials are fed into a reactor, and the high-viscosity lithium carboxymethyl cellulose is prepared through an alkalization reaction, an etherification reaction, an acidification reaction and a substitution reaction. The prepared high-viscosity lithium carboxymethyl cellulose can be used for preparing a negative electrode plate of a lithium-ion battery. Compared with the existing lithium carboxymethyl cellulose, the high-viscosity lithium carboxymethyl cellulose provided by the present application can not only reduce an application amount in preparing a negative electrode plate of a lithium-ion battery so as to save a using cost, but also promote an electrochemical performance of the material in combination with a sodium lignin sulfonate.

Abstract: A circuit for facilitating random edge injection locking of an oscillator comprises a clock signal and a digitally controlled delay line, where the digitally controlled delay line is configured to delay the clock signal, thereby generating a delayed clock signal. The circuit further comprises an edge selector configured to generate a phase select signal with a random pulse sequence. Moreover, the circuit comprises a pulse generator downstream to the digitally controlled delay line configured to generate injection pulses from the delayed clock signal for at least two phases of the oscillator based on the phase select signal.
