公共性是现代教育事业的基本特征,在市场化改革进程中,高等教育越来越体现出市场化的特质。市场具有先天的逐利性和效率优先性特征,而高等教育具有公共性的同时,也表现出相应的滞后性。高等教育的类市场改革以市场方式配置教育资源,具有准市场和不完全市场的特点。具体而言,在治理主体上,“类市场化”治理模式主张政府“集权管理”与“有限分权”相结合;在治理手段上,遵从政府“行政主导”与“有限竞争”相适配;在议程设置上,恪守“政府主导”与“社会参与”互动;在政策工具上,落实“混合性政策工具”与“强制性政策工具”的组合运用;在关键驱力上,实现“德治”与“法治”的有效融入。在对高等教育治理模式进行价值调整时,需要进一步理顺政府与高校的关系,完善市场竞争机制,持续构建更为民主、科学和法治的决策机制。

Pulse-width modulation(PWM)sprays can improve flow accuracy by adjusting duty cycle and frequency signal which accurately controls the relative proportion of opening time of solenoid *** objective of this research was to determine the impacts of PWM duty cycle and frequency on spray drift *** tests were conducted in a wind tunnel with a PWM variable-rate spraying *** airborne drift and sediment drift were determined with tracer method,and the drift potential reduction(DPR)compared with reference condition of 100%duty cycle at vertical profile and horizontal planes were calculated,*** results show that,at a given frequency,droplet size decreases with the increase of duty cycle,the main reason is that the liquid does not reach full pattern development at lower duty *** cycle has a greater impact than the frequency on spray drift,the influence weights of duty cycle on airborne drift and sediment drift were 88.32%and 77.89%,*** a lower PWM frequency,in addition to the droplet size,the spray drift may be affected by the pulsed spray *** the perspective of reducing spray drift,it is recommended that the PWM duty cycle should be set in the range of 20%-70%to reduce the potential drift in PWM *** research provides a pesticide drift reduction scheme for variable spraying technology,which can serve as a theoretical basis for PWM parameter selection.
