The invention discloses an ecological environment monitoring quality management system, and relates to the technical field of environment monitoring, and the system comprises an ecological monitoring end, an early warning adjustment end and a water quality management end, and the ecological monitoring end is used for monitoring an ecological environment and a utilization execution project of surrounding water resources in real time; the early warning adjustment end is used for predicting future parameters of the ecological environment in real time through environment parameters at the current moment and predicting whether water resources are abnormal or not through water quality standard parameters, and the water quality management end is used for conducting water source diffusion on areas with abnormal water resource utilization in real time through prediction of the ecological environment and prediction of water resource utilization rationality. According to the ecological environment monitoring quality management system, the real-time feedback of the influence of ecological environment monitoring on the water quality is increased, when the water quality is abnormal due to the change of the ecological environment, prevention can be carried out in advance, the accuracy deviation of ecological environment monitoring is avoided, variable water resources are effectively utilized for resource adjustment, and the feasibility of water resource utilization is improved.

The invention relates to the technical field of electric pole stress testing, in particular to a stress performance detection test platform and method for a new material cement electric pole, and the test platform comprises a test board for placing the cement electric pole, a rod fixing part arranged at the rear end of the test board, and a rod pressing part arranged at the front end of the test board; the rod fixing part comprises a large rod sleeve for positioning and sleeving the large-diameter end of the concrete pole, a protective cover for covering the top surface of the test board, and a linkage rod which moves back and forth along with the large rod sleeve to drive the protective cover to turn over and switch up and down at the top of the test board. According to the invention, the test motion of breaking the concrete pole is formed through the rod fixing part and the rod pressing part, and data is recorded through the pressure gauge; when the cement pole is sleeved with the large pole sleeve, the linkage rod is driven to move forwards synchronously, the protective cover is driven to turn over to the top face of the protective cover from the test table to cover the cement pole, and therefore the unsafe and untidy conditions caused by splashing of cement fragments are prevented.

A method for synthesizing a substituted nitrogen-containing quinazolinone compound is implemented by using a reinforced heating jacket, using trans-3(3-pyridyl)allylic acid, 2-(7-azabenzotriazole)-N,N,N',N'-tetramethyluronium hexafluorophosphate and ethyl 2-aminobenzoate as raw materials; and finally obtaining the product (E)-3-(4-chlorobenzyl)-2-(2-(pyridin-3-yl)vinyl)quinazolin-4(3H)-one.

The utility model relates to the technical field of polishing tables, and discloses a pulse type polishing table which comprises a base, a button switch is arranged on the left side of the front face of the base, a table body is arranged on the upper surface of the base, a rear shell is arranged on the rear side of the base and the rear side of the table body, and an air outlet is communicated with the middle of the upper surface of the rear shell. A power box is arranged at the bottom of the left side face of the rear shell, and a table top air suction opening is formed in the inner wall of the bottom of the table body. According to the pulse type grinding table, by arranging the intercepting layer, large dust generated in the grinding process is intercepted, the number of the large dust entering a draught fan is reduced, the probability that the draught fan is blocked by the large dust is reduced, and normal application of the draught fan is guaranteed; and rapid discharging of intercepted large dust is achieved, the collection speed of the large dust is increased, and a user can conveniently treat the collected large dust.
