The present invention provides an experimental method for simulating hydrothermal filling of buried-hill fractures. The experimental method for simulating hydrothermal filling of buried-hill fractures comprises: step 1, preparing experimental materials, and selecting rock cores of typical buried-hill fractured reservoirs as filling samples , and prepare a rotating and stirring autoclave as the experimental equipment; step 2, use a rotating and stirring autoclave to simulate crack hydrothermal filling under high temperature and pressure; The rate of change, through multiple comparative analysis, summarizes the law of hydrothermal filling of buried hill fractures. This experimental method for simulating hydrothermal filling of buried hill fractures can clarify the influence of factors such as lithology, fracture properties, formation temperature, formation pressure, and formation water flow rate on fracture filling, and clarify the mechanism and law of fracture hydrothermal filling.

The invention relates to an integrated pulsed ultrasound-acoustic emission transducer for detecting composite materials. Including piezoelectric sensing element, transducer housing, damping back block, time delay block, electrode, connecting seat, cover and locking ring. The broadband piezoelectric crystal is used as the ultrasonic excitation and acoustic emission signal reception, which belongs to the integrated ultrasonic-acoustic emission transducer, small in size, good in time-domain pulse characteristics, high in detection sensitivity and resolution, and very regular in ultrasonic-acoustic emission signals. Clear, qualitative and quantitative accuracy of defect detection, very good applicability, can be used for manual scanning detection and automatic scanning detection and defect imaging analysis of different composite material parts, significantly improved the composite material ultrasonic detection resolution and surface detection blind area, greatly improved The ability to detect defects in composite materials has been improved, the detection thickness can reach 50mm, the detection sensitivity can reach Ф3mm, 45mm deep defects, and the frequency selection range is 1‑7.5MHz.

The invention discloses an arrangement method for number of distribution slots in single-phase, three-phase motor fractional-slot windings. The arrangement method comprises the following steps of: calculating the numbers of slots per phase per pole as follows: q =Z / (2p*m); representing q value in the form of a mixed fraction, making b equal to the integer part of q value, c equal to the numerator of the proper fraction in the q value, and d equal to the denominator of proper fraction in the q value, namely q =b+c / d; arranging a first line list and a second line list, then determining the cycle number sequence and the cycle period number k to arrange distribution series of the fractional-slot windings. The arrangement method is simple and easy to understand, convenient to memorize, grasp and use, thus, the arrangement method is completely suitable for the arrangement of frictional-slot double-layer windings, more importantly, particularly suitable for the arrangement of various frictional-slot single-layer windings.
