春节即将来临，为让市民直观了解到燃放爆竹对空气环境造成的危害，1月27日，南昌市环境监测站现场实验对燃放烟花爆竹后空气中污染物浓度进行测量。结果显示，燃放鞭炮后，每立方米空气中的细颗粒物PM2.5从160微克增加至315微克，增加了约一倍；可吸入颗粒物PM10从355微克增加至3005微克，增加了约7.5倍；而总悬浮颗粒物TSP（大气质量评价中的重要指标）从614毫克暴增至9644毫克，增加了约14.7倍.
The analogy between steam-power and water-power is therefore quite complete. Water is in both cases the medium through which power is obtained; evaporation is also the leading principle in both, the main difference being that in the case of steam-power the force employed is directly from the expansion of water by heat, and in water-power the force is an indirect result of expansion of water by heat. The material when in its crude state not only consists of various things, such as iron, sand, coal, and lumber, that must be kept separate, but the bulk of such materials is much greater than their finished product. It is therefore quite natural to receive such material on the outside or "periphery" of the works where there is the most room for entrances and for the separate storing of such supplies. Such an arrangement is of course only possible where there can be access to a considerable part of the boundary of a works, yet there are but few cases where a shop cannot be arranged in general upon the plan suggested. By receiving material on the outside, and delivering the finished product from the centre, communications between the departments of an establishment are the shortest that it is possible to have; by observing the plans of the best establishments of modern arrangement, especially those in Europe, it may be seen that this system is approximated in many of them, especially in establishments devoted to the manufacture of some special class of work. We have now concluded our survey of the first great mental antithesis, that between reason on the one hand, and sense and opinion on the other. The next antithesis, that between reason and passion, will occupy us a much shorter time. With it we pass from theory to practice, from metaphysics and logic to moral philosophy. But, as we saw in the preceding chapter, Aristotle is not a practical genius; for him the supreme interest of life is still the acquisition of knowledge. Theorising activity corresponds to the celestial world, in which there can be neither opposition nor excess; while passion corresponds to the sublunary sphere, where order is only preserved by the balancing of antithetical forces; and the moderating influence of reason, to the control exercised by the higher over the lower system. At last the wedding-day came—an afternoon in May, gloriously white and blue. Naomi stood before her mirror with delicious qualms, while one or two girl friends took the place of her mother and helped her to dress. She wore white silk, very full in the skirt, with a bunch of lilies of the valley in the folds of the bodice, which was cut low, showing the soft neck that in contrast to the dead white of the silk had taken a delicious creamy cowslip tint. Her lovable white hat was trimmed with artificial lilies of the valley, and she had white kid gloves and tiny white kid shoes. It was Rose who had to tell Reuben. "F?ather!" cried Pete, "you can't turn him out lik this." "Reckon he is—he saw how we envied Richard." HoME老头操熟女狠狠的操逼
