The blind plate has an open-state structure and a blind-state structure. The support structure is used for connecting pipelines at two sides and providing support for the whole device. The clamping structure and the sealing structure are located inside the support structure. The clamping structure is driven by the execution mechanism, and under the drive of the execution mechanism, the clamping structure presses on the blind plate (1) to eliminate a gap between two sides of the blind plate, so that a seal is formed by means of the sealing structure. When a gap is formed away from the blind plate (1), the open/blind state of the blind plate (1) is switched.

Abstract: A consensus method and system in a consortium blockchain is provided. An example method includes, when a first consensus node in a consensus network of the consortium blockchain does not complete a consensus operation on target data on which a consensus is to be reached within a predetermined time period, the first consensus node broadcasts a ViewChange message in the consensus network based on a P set and a Q set constructed from an ECHO message. For a received ViewChange message, a second consensus node sends a ViewChangeACK message corresponding to the received ViewChange message to a second consensus primary node. When the second consensus primary node receives N?f?2 ViewChangeACK messages from consensus nodes, the second consensus primary node obtains identical P sets and a identical Q sets in the received ViewChange message. The second consensus primary node makes a view change decision based on the received ViewChange message.

Abstract: A multi-beam apparatus for observing a sample with oblique illumination is proposed. In the apparatus, a new source-conversion unit changes a single electron source into a slant virtual multi-source array, a primary projection imaging system projects the array to form plural probe spots on the sample with oblique illumination, and a condenser lens adjusts the currents of the plural probe spots. In the source-conversion unit, the image-forming means not only forms the slant virtual multi-source array, but also compensates the off-axis aberrations of the plurality of probe spots. The apparatus can provide dark-field images and/or bright-field images of the sample.
