This kind of course plays a more important role in secondary vocational computer teaching. Micro-class may still face many difficulties and challenges in today's social development, but it also has a great breakthrough. It attaches great importance to microteaching, assists normal classroom learning, and plays a certain role in promoting computer teaching in secondary vocational schools. The normal course activities can no longer lead the students to study sufficiently, and other ways of learning after class, such as micro-class, can improve the learning ability.展开更多

Methods: according to the requirements, suitable patients in our hospital were selected. There were 80 patients who met the standards. They received conventional treatment and micro-implant anchorage treatment respectively. The orthodontic status of the patients and the adverse reactions caused by the patient's body during the treatment in the hospital were studied. According to the clinical orthodontic indicators of the patients, the data of the two groups were compared in various aspects. Results: the orthodontic correction of the patients in the observation group achieved the expected effect after treatment. There were 39 cases without any problems, accounting for 97.50% of the population in this group, which was significantly higher than 80.00% in the control group. After effective treatment, 1 case had adverse reactions, accounting for 2.50% of the population in this group, which was not significantly less than 15.00% in the control group, and the difference was significant. After treatment, the molar displacement distance of the observation group was (3.31±0.32) mm, which was significantly smaller than that of the control group ( 5.21 ± 0.53 ) mm. ( 2.51±0.72 ) mm, the difference of incisor inclination in the observation group after treatment was ( 27.51±6.62 ) degrees, significantly larger than that in the control group ( 15.16±4.53 ) degrees, and the difference was significant (p<0.05). Conclusion: the use of micro-implant anchorage in clinical treatment of patients with orthodontic treatment has obvious advantages, which can help improve the oral deformity of patients, allow patients to have better treatment effects, and reduce the probability of adverse reactions, which is worthy of promotion.展开更多

[Method]2% Imidacloprid GR were selected and applied in the soil for field efficacy trial. [Result] The optimum dosage of 2% imidacloprid GR was 30 kg/hm^2（ active ingredient 600 g）,which can be mixed with fertilizer（ 30 kg pesticide and 40-80 kg fertilizer per hm^2） once combined with sugarcane planting management or big ridging during February and June. The control effects against C. lanigera and B. serratus could be more than 98. 2% and 81. 1%,respectively. The actual yield and sugar content in various pesticide treatments were increased by 33 390 kg/hm^2 and 6. 6% respectively compared to blank control. [Conclusion]2% imidacloprid GR has good control effects on C. lanigera and B. serratus. It is a new pesticide with ideal sustained-release,long-lasting and low-toxin effects against C. lanigera and B. serratus. Therefore,it could be used alternatively with other pesticides,to delay production and development of drug resistance.展开更多
