The invention discloses a test detecting tool for compression-type packer rubber sleeves. The test detecting tool comprises a center tube (1), a deblocking tube (24) and a canister-shaped hydraulic cylinder sleeve (10). The right end of the hydraulic cylinder sleeve (10) is in seal connection with the deblocking tube (24) by a canister-shaped connecting ring (16); a closed annular cavity (26) is formed between the hydraulic cylinder sleeve (10) and the center tube (1); a canister-shaped piston (13) and a measuring ring (11) which is sleeved outside the deblocking tube (24) are disposed in the annular cavity (26); the piston (13) can push a baffle ring (5), a piston rod (7) and the measuring ring (11) to slide along the axis of the center tube (1); and a through hole (27) is disposed on the sidewall of the deblocking tube (24) and between the piston (13) and the connecting ring (16). The test detecting tool of the compression-type packer rubber sleeves not only can detect a plurality types of packer rubber sleeves, but also has the advantages of simple detection mode, high efficiency, high accuracy, low cost and the like.

The invention relates to an operation method and system. The operation method comprises that a terminal receives a pressing operation; the fingerprint of the pressing operation is obtained; the matching proportion of the fingerprint of the pressing operation to a prestored fingerprint is obtained, in dependence on the matching proportion, the proportion of the touch area of the pressing operation to the area of the prestored fingerprint is obtained. Compared with the detection mode of a capacitive screen, the detection mode is more accurate; compared with the detection mode of an infrared emitter and a receiver, the detection mode is lower in cost; furthermore the confidentiality and safety of the pressing operation are guaranteed.

The invention relates to an automatic pressure pin, choke plug and pressure plate system for a camshaft, which comprises a system support frame, wherein a pressure plate device, a gluing device, a pressure pin device, a pressure choke plug device and a leak detection device are mounted on the system support frame; an angular locating detection mechanism is arranged in the pressure plate device; and a manipulator for conveying the camshaft among the devices, and an industrial personnel computer for controlling the devices and the manipulator to work automatically are arranged on the system support frame. According to the system, multiple processing procedures during a camshaft processing course are integrated, so that continuous operation of camshaft processing is achieved; an automatic feeding mechanism is adopted in the processing procedures, so that automatic feeding and locating of a workpiece are achieved, potential safety hazards during a workpiece feeding course are reduced, the processing time is saved, and the manpower investment is reduced; and the leak detection device and the angular locating detection mechanism are adopted, so that automatic detection on the camshaft is achieved after the corresponding processing procedures of the camshaft, and a qualified rate of the finished camshaft is ensured.

The invention discloses a software protection method based on network, a client side and a server, which is used for improving the accuracy and the effectiveness for detecting whether client side software is distorted. The method comprises: a server side receives a program operation request sent by the client side and sends random data to the client side according to the program operation request; the client side adopts a set Hash algorithm to determine a first Hash value according to client side identification, random data and a program code segment which is stored in the client side and corresponds to the edition information of software to be operated; the server side adopts the set Hash algorithm to determine a second Hash value according to client side identification, random data and a program code segment which is stored in the client side and corresponds to the edition information of software to be operated; the first Hash value and the second Hash value are compared to determine whether the client side is permitted to execute the program according to the comparison result. The technical scheme of the invention improves the accuracy and the effectiveness for detecting whether client side software is distorted.

The invention provides a steam cooking appliance, a water shortage detection method and a water shortage detection device thereof. The water shortage detection method of the steam cooking appliance includes the following steps: detecting whether the water tank is installed in place, if the water tank is installed in place, then cooking, otherwise it shows water shortage; The time interval between on and on, if the time interval is greater than the first preset value, water shortage will be displayed. In the water shortage detection method provided by the present invention, firstly, by detecting whether the water tank is installed in place, the problems often committed by users such as forgetting to insert the water tank are solved, and the water shortage error report is effective; by performing the final water shortage detection control at the steam generator end, the detection method It is more accurate, reduces the chance of false alarm of water shortage, and solves the problem of long-term water accumulation in the water tank caused by premature report of water shortage, which affects the safety and sanitation of cooking food.

The invention discloses tomato spotted wilt resistance gene Sw-5b close linkage SNP site acquisition and marker development. The invention provides application of substances for detecting polymorphismor genotype of SNP724 sites in a tomato genome in identification or auxiliary identification on whether spotted wilt resistant Sw-5b genes exist in the tomato genome or not, or application of substances for detecting polymorphism or genotype of SNP724 sites in a tomato genome in preparation identification or auxiliary identification on whether spotted wilt resistant Sw-5b gene products exist in the tomato genome or not. Experiments prove that an SNP marker SNP724 which is interlocked with the tomato spotted wilt resistance gene Sw-5b is developed, the SNP marker can be used for a high-throughput molecule detection platform, and compared with a second-generation molecular marker, the SNP maker has the advantages that the detection mode is simple, convenient and accurate, and the detectionefficiency is high.
