泉州市厨余垃圾资源化利用问题初探

垃圾分类是实现垃圾减量化、资源化、无害化,避免“垃圾围城”的有效途径。自2017年推动城市生活垃圾分类工作以来,泉州市相关政策和机制框架逐步完善,居民小区生活垃圾分类工作基本实现全覆盖,但厨余垃圾分类及资源化利用工作在相对薄弱。该文通过调研分析,指出厨余垃圾分类和资源化利用工作在泉州市推进垃圾分类工作中的重要价值,并通过技术对比分析,提出进一步推动泉州厨余垃圾分类和资源化利用的措施。     

A Novel Atmospheric Pressure Plasma Fluidized Bed and Its Application in Mutation of Plant Seeds

An atmospheric pressure plasma fluidized bed (APPFB) is designed to generate plasma using a dielectric barrier discharge (DBD) with one liquid electrode. In the APPFB system, the physical properties of DBD discharge and its application in plant-seed mutating are studied fundamentally. The results show that the generated plasma is a typical glow discharge free from filament and arc plasma, and the macro-temperature of the plasma fluidized bed is nearly at room temperature. There are no obvious changes in the pimientos when their seeds are treated by APPFB, but great changes are found for coxcombs.     

沉沉暗夜里的一道闪电－－谈《雷雨》中的蘩漪形象

试就《雷雨》的典型环境具体分析蘩漪性格的形成过程及其典型意义，充分肯定这一光辉形象所具有的积极的时代意义，对她所做的力所能及的反抗给予深切地理解和同情。同是批驳一些论者对蘩漪形象的折衷态度：既肯定其“离经叛道”的合理性，又以“心理变态”，“阴鸷”，“暴戾”等词语予以否定。笔者认为：蘩漪作为三十年代的女性，不甘被役，被侮辱的生活，义无反顾地奋起抗争，具有不容置颖的人性的光辉，是沉沉暗夜里的一道犀利的闪电。
