Abstract: Disclosed are an array cutting knife-type cotton topping machine and a control method thereof. The cotton topping machine includes cameras, controllers, a tacho-generator and a plurality of groups of topping assemblies arranged in a left-right direction; the cameras and the tacho-generator are connected to the controllers; and a plurality of topping devices staggered left and right are arranged for each planting row. In the present disclosure, by densely arranging low-cost topping devices and determining which topping devices are switched to an operating state for topping according to visually determined top bud positions, the potential problems in the prior art of the damage to other parts of the plant or the unnecessary intertwining of branches and leaves are avoided.

Abstract: A method and a system for determining interval time for testing of a server, and a device and a storage medium are provided. The method includes: evenly dividing multiple servers into multiple groups of servers, and performing multiple rounds of testing on each group of servers; calculating performance values of each group of servers in each round of testing according to a weight corresponding to each influencing factor, and packaging and writing the performance values and interval time corresponding to the performance values in a database; and collecting, at every other preset time, current values corresponding to influencing factors in an actual running process of a server, calculating a current performance value of the server based on the current values according to the weight corresponding to the respective one of the one or more influencing factors, and determining, from the database, interval time corresponding to the current performance value.

Abstract: A method and a system for determining interval time for testing of a server, and a device and a storage medium are provided.

Abstract: Disclosed are a reusable software packaging method and device. The method includes: uploading an original file and an execution script, storing metadata information, verifying the original file and the execution script, packaging the original file, the encrypted execution script and a corresponding table, generating a reusable software package, verifying and decompressing the package, decrypting the execution script and the corresponding table, uploading the original file and the execution script, storing metadata information of the corresponding table, and updating the corresponding table. The present application improves the software deployment effect and the operation and maintenance efficiency.

Abstract: The present invention relates to a method of preparing wear and cut resistant UHMWPE fibers. In the method, a resin material is added into a ball grinder, and the temperature is controlled, and then a mother liquor is added slowly into the ball grinder and mixed uniformly, and the mixed solution is vacuumed in a sealed container for several hours and extruded by a twin screw extruder, a metering pump, and a spin beam, and finally processed with drafting and hot drawing and winding formation. The fiber so manufactured has the features of soft touch and comfortable wearing.
