The invention discloses a double-end traveling wave distance measurement method and device for coping with time synchronization loss and a storage medium, and the method comprises the steps: calibrating and storing the inherent phase offset of power frequency voltages at two ends of a line in advance when time synchronization is normal; when a fault occurs after the time synchronization signal is lost, through identifying a power frequency voltage zero crossing point before the fault and combining with the phase offset, or carrying out cross-correlation calculation on a power frequency waveform before the fault at one end and a waveform at the other end, realizing accurate alignment of recording data at the two ends on a time axis, so as to establish a relative synchronization time reference; then, accurately identifying the arrival time of the wave heads of the initial traveling waves at the two ends by using a wavelet transform modulus maximum method; and finally, based on the aligned time reference, calculating the time difference of the traveling wave arriving at the two ends, thereby realizing accurate fault positioning independent of a satellite time synchronization signal. The device and the storage medium are used for implementing the method. According to the method, the robustness and the usability of the power distribution network traveling wave fault positioning system under the time synchronization abnormal working condition are effectively improved.

The processing method includes a holding step of holding the base of the bonded wafer by a chuck table (21), an edge trimming step of removing the chamfered portion by rotating the chuck table while causing a blade grindstone (54) to cut into the chamfered portion of the wafer of the bonded wafer held by the chuck table, and a grindstone tip correcting step of correcting a tip shape of the blade grindstone before or after the edge trimming step. In the grindstone tip correction step, the blade grindstone is made to cut into the W12 (upper side) of the wafer of the bonded wafer.SELECTED DRAWING: Figure 2
