The invention relates to the technical field of separation of active ingredients of traditional Chinese medicines, in particular to a method for optimizing enzyme-assisted extraction of total triterpenes of radix tetrastigme based on a response surface method. According to the method, based on a Box-Behnken response surface method, the mass concentration of Sebienic acid is taken as a response value, four response variables including the enzyme addition amount, the enzymolysis pH value, the enzymolysis temperature and the enzymolysis time are selected, the optimal point of a single-factor experiment is taken as the center, the upper portion and the lower portion of the center are each provided with a level value to serve as the response surface level, multiple regression analysis is carried out on data of all the response variables, and the optimal point of the single-factor experiment is obtained. A regression equation is obtained, and optimal enzymolysis conditions are obtained: cellulase ...

The invention discloses a CPT atomic clock which is applied to the field of atomic frequency standards. The CPT atomic clock comprises a VCSEL, a 1/4 lambda wave plate, a lens and an optical cavity, and the VCSEL is used for generating laser required by light pumping of the CPT atomic clock; the lens and the optical cavity are arranged between the VCSEL and the 1/4 lambda wave plate; the lens is arranged on one side close to the VCSEL, and the lens is used for converging laser emitted by the VCSEL into Gaussian light; the optical cavity is arranged on one side close to the 1/4 lambda wave plate; the inner surface of the cavity mirror of the optical cavity comprises a reflecting mirror which is used for adjusting the amplitude of different frequencies in the laser signal so as to eliminate the high-order sideband. According to the scheme, the reflecting mirror of the optical cavity can be used for adjusting the amplitudes of different frequencies in the optical signals, eliminating high-order ...
