Provided are a display substrate and a preparation method thereof, and a display apparatus. The display substrate includes a display region and at least one hole region located in the display region, the hole region includes a function hole and a partition region surrounding the function hole, the partition region is provided with at least one partition dam surrounding the function hole; the partition dam includes a first partition layer disposed on a base substrate and a second partition layer disposed on a side of the first partition layer away from the base substrate, at least one partition layer includes a second sub-layer and a third sub-layer disposed on a side of the second sub-layer away from the base substrate, the third sub-layer has a protrusion with respect to a sidewall of the second sub-layer, and the protrusion and the sidewall of the second sub-layer form an inwardly recessed structure.

Display substrate and preparation method thereof, and display apparatus each including partition region provides with at least one partition dam surrounding function hole

The present disclosure relates to a static CT detection device, including: a shielding body, formed with a detection channel through which an object under detection can pass; a ray source, emitting rays for detecting the object under detection when the object under detection passes through the detection channel; and a detector, for acquiring the rays emitted by the ray source and having passed through the detection channel, wherein the shielding body is formed with an opening portion, and the opening portion extends from an inlet of the detection channel to an outlet of the detection channel.

Static CT detection device

A device comprises: at least two lead curtains; a supporting assembly comprising a working area and a standby area; a first transmission assembly to drive the lead curtains to move in a conveying channel; and a second transmission assembly to transfer the lead curtains between the standby area and the working area, wherein the second transmission assembly transfers the lead curtains from the standby area to the working area, so that the lead curtains fall into a starting point of the conveying channel and are located behind an article to be detected; the first transmission assembly drives the lead curtains to move with the article to be detected in front and drive the lead curtains to move from the starting point of the working area to a starting point of the standby area; and the second transmission assembly drives the lead curtains to enter and move in the standby area.

Lead curtain protective device for detecting device and ray shielding method

A method for real-time and in-situ monitoring of freeze-thaw damage to concrete, comprising embedding pairs of gradient electrical resistance probes into a surface of concrete being monitored at a depth of 0-50 mm, the paired gradient electrical resistance probes having an anti-corrosion metal bar, with the buried depth gradient of different pairs of electrical resistance probes being in the range of 1 mm to 20 mm, and the buried depth gradient of the pair of electrical resistance probes nearest to the surface being less than 5 mm; transmitting an impedance value of the concrete measured by the paired gradient electrical resistance probes to a monitoring center for processing; and evaluating a spalling status of freeze-thaw damage to the concrete based on changes in impedance value which may be abrupt. Real-time in-situ monitoring of the freeze-thaw damage of concrete can be achieved by the electrical resistance probes and monitoring center of this invention.
