The invention relates to a user terminal and a detection method of a neighbor cell thereof. The method comprises: receiving data that are sent by a base station and include a PSS; carrying out correlation operation on the received data and a local PSS sequence; and for peak values obtained by the correlation operation, shielding peak values except peak values corresponding to peak zones of different detected synchronous group cells and detecting information of other synchronous group cells based on the peak values not shielded. Each synchronous group corresponds to a different peak zone. With the detection method, a computing load of a neighbor cell detection process and a false detection rate of the neighbor cell detection process can be reduced.

The invention discloses an emptying signal test circuit for an optical storage unit, which is characterized in that the emptying signal test circuit is formed by serially connecting two monostable circuits, an inverter F, an operational amplifier H and a gating switch, wherein the monostable circuit consists of a double-D trigger with six ports, a capacitor and a variable resistor; and an output signal from an emptying reading circuit is accessed to the first monostable circuit, is used as a VB signal output and a signal input of the next monostable circuit after being processed by the inverter and the operational amplifier, and finally is output as an RS signal. An emptying signal of the test circuit is generated independently by another circuit and is not dependent on a reset signal; andthe test circuit can flexibly adjust the time of emptying pulse, the width of signals and the positions of the emptying signal and the reset signal for the convenience of testing the working conditions after an optical storage sensor is butted with the circuit under different emptying conditions; and compared with the prior art, the test circuit has the advantages of good operability and practicability, and convenient adjustment of signal parameters.

The invention discloses a jujube preservation method and a product thereof. The method includes steps: deactivating: breaking walls of jujube cells to release cell content to stop cell biological metabolism; maturing: placing a wall-breaking treatment product to enable jujube to be mature; preserving: freezing a mature product. Wall breaking of the jujube cells is realized through deactivation, sothat the cell content having high-quality jujube fragrance and taste is obtained, cell biological metabolism is stopped, and cryogenic burn is avoided. Sugar is converted into tartaric acid through maturing initiatively, so that the product is easier to digest and absorb and good for health; better taste and fragrance are obtained through maturing, and picked jujubes different in mature degree are enabled to be uniform in mature degree, so that convenience is brought to industrial production management. Freezing slows down and even stops chemical reaction of components in the jujube, so thatlong-time preservation can be realized without adding any preservative. The product is convenient and elegant in eating, convenient for transportation and high in efficiency, and a worldwide problem of jujube transportation and preservation is solved.
