The present invention discloses a stepped hole method-based internal residual stress measurement method. The method includes the following steps that: 1) an end surface of a workpiece to be measured is milled through using a milling cutter according to a preset measurement depth, so that a recessed hole can be formed at the end surface of the workpiece to be measured; 2) residuals on the bottom surface of the recessed hole which are generated in the production process of the recessed hole are cleaned, and a spray tube is inserted into the recessed hole, and the bottom of the recessed hole is uniformly sprayed and coated with matte white paint; 3) a seal is produced, a plurality of marking points are engraved on an end surface of the seal, and the seal is inserted into the recessed hole, and the bottom surface of the recessed hole can be printed with marking points; 4) the initial state information of the marking points of the bottom surface of the recessed hole is obtained; 5) the center of the bottom surface of the recessed hole is drilled through using a blind hole method, so that a blind hole can be formed at the center of the bottom surface of the recessed hole; 6) residuals generated in the drilling of the blind hole are cleaned, and then, the final state information of the marking points of the bottom surface of the current recessed hole is obtained; and 7) the residual stress state of the center of the bottom surface of the recessed hole is calculated. With the method adopted, the measurement of the internal residual stress of a large-depth portion of a workpiece can be realized, measurement accuracy is high, and the workpiece will not be damaged.

The invention relates to the technical field of communication and provides a method for collaboration application among split type terminals and the split type terminals. Each split type terminal comprises a host computer and at least one sub-computer. The method for the collaboration application among the split type terminals comprises the steps that an application needs to be collaborated is analyzed according to a message after the sub-computer receives the message, whether the sub-computer supports the application is judged by the sub-computer itself, an application collaboration command of the application is sent to the host computer by the sub-computer if the sub-computer does not support the application, and then the application is executed by the host computer according to the application collaboration command. Therefore, the method for the collaboration application among the split type terminals has the advantages that the application collaboration can be achieved among the split type terminals, and user operation can be more convenient and more efficient.

The invention relates to the technical field of underground drilling construction and discloses a drilling deviation correction method and device based on following of a casing pipe. By means of the method, by adjusting the front and rear relative positions between a drilling head and the matched casing pipe on the outer side, the size of an acting force of a stratum on a steering selection surface of an end head of the casing pipe during drilling is changed to adjust the jacking direction of the casing pipe. The device is simple in structure, high in precision of deviation correction and convenient to operate.

The invention relates to a spanner, and belongs to the technical field of hardware tools. The spanner comprises a main spanner body, an auxiliary spanner body and a connecting shaft. The main spannerbody comprises a main spanner head, a main sleeve and a main spanner handle and is clamped with a bolt or nut to be demounted and mounted for demounting and mounting work, and the main spanner body isused as a bent handle for increasing the force arm when the auxiliary spanner body works. According to the spanner, a pipeline can penetrate through the spanner, and a nut on the pipeline can be mounted and demounted. The spanner can also be used for demounting and mounting work of a nut or bolt in the narrow and small space or a deep concave place. The technical problem that a sleeve hole of anexisting sleeve spanner is sealed, the pipeline cannot penetrate through the spanner, and the activity of the existing open spanner in the narrow and small space is limited is solved. If the main spanner body works, the auxiliary spanner body serves as the bent handle. If the auxiliary spanner body works, the main spanner body serves as the bent handle.
