    摘要： A fine atomic clock includes a particle source, an MW filter, an atomic gun, a Magneto-MW Trap (MMT) unit, an energy injection unit, and a probing unit. The particle source is used for emitting particles. The MW filter is used for receiving the particles and generating a plurality of coherent MW of particle beams. The plurality of coherent MW of particle beams is used for forming a virtual space-time lattice in an enclosed space. The atomic gun is used for emitting a sample. The MMT unit is used for utilizing a magnetic field to trap the sample in the virtual space-time lattice, and utilizing the plurality of coherent MW of particle beams to cool down the sample. The sample corresponds to fermions or molecules. The energy injection unit is used for injecting energy into the sample to activate the sample into an excitation state. The probing unit is used for activating emission of the sample. An emission frequency of the sample corresponding to a characteristic emission frequency of the sample, and the emission frequency is utilized to generate a standard time signal.

    摘要： Disclosed is a method of predicting cycle life of a secondary battery comprising a carbon-based hybrid negative electrode, comprising: measuring a lattice d-spacing of a carbon based negative electrode active material of a target carbon-based hybrid negative electrode using an X-ray diffractometer during charging/discharging of a target secondary battery comprising the target carbon-based hybrid negative electrode comprising a carbon based negative electrode active material and a non-carbon based negative electrode active material, and plotting a graph of changes in lattice d-spacing value as a function of charge/discharge capacity (X axis); calculating a target slope difference corresponding to a difference in slope value changed with respect to an inflection point of the graph during discharging in the plotted graph; comparing the target slope difference with a reference slope difference corresponding to a difference in the slope value changed with respect to an inflection point in a graph showing changes in lattice d-spacing value as a function of charge/discharge capacity (X axis) of a reference secondary battery; and predicting if the cycle life of the target secondary battery is improved compared to the reference secondary battery from a result of the comparison.
