Abstract: The present application discloses a method for rapidly identifying the resistance of wheat to black point disease caused by Bipolaris sorokiniana, where testing takes places in an indoor, controlled environment. The test method includes surface sterilization of wheat seeds, and cultivating wheat seedlings from the sterilized wheat seeds; preparing conidial suspension of Bipolaris sorokiniana, and spraying the conidial suspension on the seedlings at one-leaf-one-shoot stage; recording the percentage of the diseased leaf area in total leaf area of the first leaf of the wheat seedling on the 10th day of inoculation; calculating the black point incidence of the wheat according to an equation, and then evaluating the resistance of wheat to black point disease caused by Bipolaris sorokiniana through the black point incidence.

Abstract: A high-pressure gas cylinder valve for vehicle includes a valve seat having a gas charging runner and a gas supplying runner. A check valve is connected in series onto the gas charging runner, and the check valve and a solenoid valve are connected in series sequentially onto the gas supplying runner in a gas flow direction. A portion of the gas supplying runner located downstream of the solenoid valve is jointly connected to a portion of the gas charging runner adjacent to a gas inlet end and supplies gas to outside through a gas inlet of the gas charging runner when the gas supplying runner supplies gas. The gas cylinder valve further includes a flow-blocking buffer structure connected in series onto the gas supplying runner and located downstream of the solenoid valve and upstream of an intersection of the gas supplying runner and the gas charging runner.

Abstract: A sensor assembly, a force detection device and method, and construction machinery, the sensor assembly comprising a connecting part used for connecting a base to be tested and a bearing part used for bearing, the bearing part being connected to the connecting part, the bearing part comprising at least two sensing units with different measuring ranges, and the at least two sensing units being arranged to have a different initial gap (b1, b2) from the connecting part, so that corresponding initial gap (b1, b2) are eliminated when a load applied to the bearing part reaches different extents. The different initial gaps (b1, b2) are eliminated by means of the load reaching a different extent, so that the sensing units with different measuring ranges can provide detection feedback in the respective working conditions in which the units have the highest measurement precision and thereby ensure the accuracy of detection results.
