The invention relates to the technical field of tunnel boring machine engineering machinery, in particular to a round cutter box capable of having a disc cutter replaced bidirectionally. The round cutter box capable of having the disc cutter replaced bidirectionally comprises a ringlike cutter box body and two cutter shaft fastening units, wherein the ringlike cutter box body is fixed on a cutter disc and is in a cylindrical shape, the cutter shaft fastening units are arranged at the inner side of the cutter box body and are in central symmetry, and each cutter shaft fastening unit comprises a load-bearing guide bar, a limiting guide bar, a wedge-shaped pressing block, a tensioning block, a tension bolt and nuts, wherein each load-bearing guide bar is fixed to the inner wall of the cutter box body, each limiting guide bar is fixed to the inner wall of the cutter box body and arranged in a mode that the limiting guide bar corresponds to the corresponding load-bearing guide bar and a certain included angel is formed between the limiting guide bar and the corresponding load-bearing guide bar, and each wedge-shaped pressing block, the corresponding tensioning block, the corresponding tension bolt and the corresponding nuts are arranged between the corresponding load-bearing guide bar and the corresponding limiting guide bar in a matched mode. By means of the round cutter box, the disc cutter can be replaced from either the back side or the front side of the cutter disc, the cutter is replaced from the back side in the construction process of a tunnel boring machine, the cutter is replaced from the front side in the production, assembling and debugging process of the tunnel boring machine, and the cutter box body of the round cutter box is of a round structure, so that the cutter box body on the cutter disc is made to be capable of saving the space and being subjected to even stress.

The invention discloses a method for automatically testing the performance of windows desktop software, and belongs to the technical field of software testing. The method comprises the following steps: 1, acquiring a test case set, and setting an iterative threshold; 2, recording the probability of switching between any two test cases as Pij, and establishing an array for storing the probability of switching between all nodes; 3, initializing all nodes, and initializing the pheromone strength among the nodes to be 1 and the pheromone among the nodes to be 0; 4, randomly selecting a group of test case combinations, and updating pheromones according to the change of system resources after the execution of the test case combinations is completed; 5, if resource growth occurs, additionally increasing pheromones among the current nodes, and updating global pheromones; 6, when the pheromone is higher than the threshold value, entering a confirmation link, and repeatedly executing the path inthe confirmation link to update the pheromone according to the judgment result; and 7, terminating the test after the number of algorithm iterations exceeds a threshold, and outputting a test conclusion.

The invention discloses a large-section soft ground tunnel full-section construction structure and a construction method. The structure comprises a tunnel excavation and anchorage system formed by multiple tunnel excavation and anchorage mechanisms for excavating and anchoring rock masses in front of a working face, wherein each tunnel excavation and anchorage mechanism comprises an anchor rod, ananchorage mechanism and a rotary excavation cutter. The method comprises the steps of (1) constructing a rear-end segment; (2) constructing a next tunnel segment; and (3) repeating the step (2) for one time or multiple times until the tunnel construction process is accomplished. The large-section soft ground tunnel full-section construction structure provided by the invention is reasonable in design, simple and convenient to construct and good in use effect; the construction quality is easy to control; and when the rock masses in front of the working face are effectively dynamically anchoredby the tunnel excavation and anchorage system formed by adopting the multiple tunnel excavation and anchorage mechanisms, a large-section soft ground tunnel can be mechanically full-section excavatedat the same time, so that the tunnel surrounding rock and tunnel structure is ensured to be stable, the construction risk is reduced, the construction progress can be effectively accelerated, and thetunnel construction quality is easy to control.

The embodiment of the present application provides an information generation method and cloud service platform based on intelligent online communication and big data. Considering that the online communication fault interaction behavior is characterized by merging the online communication fault data into the original service access big data and the associated The data recording area corresponding to the service access big data, therefore, the online communication failure data in the data recording area corresponding to these original service access big data will produce some specific data recording areas inconsistent with the original access data. Based on this, attention should be paid to the service access data. The characteristic information of the data collection itself and the characteristic information of the online communication failure data collection can effectively discover the optimized communication interaction objects corresponding to the service access big data collection, so as to facilitate subsequent communication optimization for the optimized communication interaction objects in a timely manner.

The invention relates to a passenger flow time sequence clustering optimization flight regulation and control method and system, and the method comprises the steps: S1, carrying out the grouping statistics according to flight historical orders, and obtaining flight data; S2, performing normalization processing on the flight data to obtain normalized flight data; S3, calculating KL divergences of the normalized flight data in pairs according to dates, and distributing the normalized flight data to a preset interval according to the KL divergences; and S4, clustering the normalized flight information of each interval to obtain the category of each piece of normalized flight information, and taking the category as reference information for optimizing flight regulation and control. According to the method provided by the invention, similar conditions of the aviation historical orders can be effectively mined, the similar conditions are provided for flight planning personnel as reference for optimizing flight regulation and control, the planning cost is saved, and the efficiency is improved.
