The invention relates to an energy efficiency analysis method of interlocking equipment. The energy efficiency analysis method comprises: data sampling: carrying out equal-time and equal-distance sampling on energy consumption correlation parameters of at least two sets of equipment in the interlocking equipment, so as to obtain sampled data within certain time; data pre-processing: carrying out the data pre-processing on the actually measured sampled data, eliminating abnormal data therein and complementing missing data; framing operation: dividing the sampled data subjected to pre-processing of each set of equipment into a plurality frames through adopting an overlapping and sectioning manner, wherein each frame corresponds to one time period with equal duration and a frame shifting length of each frame is smaller than a frame length; correlation coefficient calculation: taking the sampled data in each frame as a foundation and calculating a correlation coefficient rXY in each frame of the energy consumption correlation parameters of at least two sets of equipment in the interlocking equipment; abnormity judgment: taking a frame with the correlation coefficient lower than a judgment threshold value as an abnormal frame. The energy efficiency analysis method of the interlocking equipment, provided by the invention, can be used for assisting to check reasons for forming interlocking abnormity and guiding the equipment to be correspondingly adjusted; whole operation of a system can be more stable and more energy can be saved through adopting the method.

The invention relates to the field of mobile communications, in particular to a signal compression method and apparatus. In order to solve the problems of high processing delay and high compression loss in the existing signal compression methods, the method comprises, based on the respective preamble symbol bits of the first i signal and the first q signal included in the initial iq signal, determining the overall displacement length, and based on the overall shift length, performing shift processing on the first I signal and the first Q signal, obtaining a second I signal and a second Q signal, and according to the preset bit width, a second I signal and a second Q signal are truncated, the third I signal and the third Q signal are obtained, and the target IQ signal is generated based onthe third I signal and the third Q signal. Thus, no additional AGC processing is required, and the time delay is greatly reduced. Moreover, since part of the IQ signal is completely reserved, the signal fidelity is high, and the compression loss is greatly reduced.

A molding machine includes a fixed mold and a movable mold. The molding machine is a so-called micro-molding machine which provides less than 1.5 KN of the mold clamping force for clamping the fixed mold and the movable mold. A positional shift length between both molds is preset at ±20 μm or less. Further, cavities are inserted in base molds of both molds respectively. Furthermore, cores are inserted in the cavities. The position of each cavity is adjustable with respect to each associated base mold. The position of each core is also adjustable with respect to each associated cavity. Moreover, the molding machine can simultaneously mold a plurality of optical components.

In a method and magnetic resonance apparatus (5) for reconstructing an MR image (43) of a volume segment within an examination object (O), MR data within the volume segment are acquired according to a separation method by MR data for a k-space line being acquired respectively in steps while a readout gradient is activated in the same readout direction. An image (41) of a first substance and an image (42) of a second substance are thereby reconstructed. A shift length (V), by which the image of the first substance and the image of the second substance are displaced relative to one another due to the chemical shift in the readout direction is determined. The image of the first substance and / or the image of the second substance is shifted as a function of the shift length, to compensate for the relative displacement between the images of the first and second substances in the readout direction due to the chemical shift. An MR image is generated by combining the images of the first and second substances. A data carrier is also provided.

By the method of measuring a gap depth of a thin film magnetic head for horizontal magnetic recording, the gap depth of a write-magnetic pole can be easily and correctly measured. The method comprises the steps of: forming a first standard marker; measuring a distance between an actual position of a rear end of a lapping guide and the position of the first standard marker; calculating a lapping guide shift length; forming a second standard marker; measuring a distance between an actual position of a zero throat and a position of the second standard marker; calculating a zero throat shift length; and calculating an actual gap depth of a write-magnetic pole by adding the lapping guide shift length and the zero throat shift length to a designed gap depth.
