This method is also applicable in the acetolysis of other cyclic ethers, such as methyl substituted THF and tetrahydropyran and 1,4-dioxane which is less reactivity.展开更多

Methods: a total of 88 patients underwent blood lipid test in the clinical laboratory department of our hospital from January 2021 to January 2022.Classification test and drag-test are used to compare the accuracy of test results and compare the test cost. Results: the positive rate of the test result is different from the test method, and the data is meaningful (P <0.05);the missing rate is lower than the test-test, the data is meaningful (P <0.05);the test cost is lower than the conventional test, and the data is meaningful (t=23.785, P=0.000).Conclusion: for the clinical biochemical testing of blood lipid, the testing accuracy of the graded test method is higher, which can meet the clinical needs, and can reduce the testing cost, and can be promoted.展开更多

It is also an effective way to improve students' interest in music and educate students. Multi-modal music teaching can effectively improve classroom teaching efficiency and optimize students' classroom experience. Then how should teachers carry out the teaching of multi-modal music evaluation?展开更多
