There is one man of genius, who has done much for this philosophy of life, whose literary value has never yet been rightly estimated;--I mean Emanuel Swedenborg. The most imaginative of men, yet writing with the precision of a mathematician, he endeavored to engraft a purely philosophical Ethics on the popular Christianity of his time. Such an attempt, of course, must have difficulty, which no genius could surmount. But he saw and showed the connection between nature and the affections of the soul. He pierced the emblematic or spiritual character of the visible, audible, tangible world. Especially did his shade-loving muse hover over and interpret the lower parts of nature; he showed the mysterious bond that allies moral evil to the foul material forms, and has given in epical parables a theory of insanity, of beasts, of unclean and fearful things.
我们是否确切的明晓这一切的意义:小桶中的食物,平锅里的牛奶,街道上的民谣;从船上来的消息;眼睛的一瞥;身体的结构和姿态;——告诉我这一切的究竟;向我展示隐藏在其中的最高精神原由,它的崇高外现;这原由总是隐密其踪迹于自然的边缘和远端;请让我洞悉每一生活细节中充盈的两极律,这使它们与永恒律并列而陈;还有那修理作坊,那铧犁和那织机工,这一切,光影舞动其上并为诗歌咏唱着——因此世界不再是索然无味的杂物堆积或储藏室,它有型有序;这里不再有无足轻重也没有惶惑;只有纯粹的设计,它连接了遥远的高峰和最深的低谷,为它们注入生命。

They have close relationship as the former may provide new ideas and approaches for the later, while the later may be the simulation for the former and gives it helps in degradation products identification and mechanism explanation. It is necessary to choose a suitable system, which has high potential of treating EDs and close relationship to the natural environment, to combine the researches in the two aspects. Our group has been engaged in researches on the photochemical properties and application to water pollution control of different ferric species including Fe -OH complexes, Fe -polycarboxylate complexes, Ferric oxides and Fe -humic acid complexes. Fe -oxalate complexes system has higher efficiency than the other ferric species systems in photooxidation and degradation of organic compounds. This thesis is focused on the photodegradation of nine EDs estradiol (E2), estrone (E1), 17α-ethynyl estradiol (EE2), diethylstilbestrol , bisphenol-A , 4-Nonylphenol , 4-Octylphenol , di-n-butyl phthalate , and di (2-ethylhexyl) phthalate .
因此从处理效率和环境化学意义两方面考虑,结合本课题组在不同铁形态(包括Fe-OH配合物、Fe-多羧酸配合物、Fe氧化物、Fe-腐殖酸配合物等)的光化学特性及其在水污染控制中的应用方面较系统的研究工作基础,本论文选择了四类共9种典型的内分泌干扰物(雌二醇(E2)、雌酮(E1)、17α-乙炔基雌二醇(EE2)己雌酚、双酚A、壬基酚、辛基酚、酞酸二丁酯和酞酸二乙基己基酯),研究了它们在Fe-草酸盐配合物体系中的光降解效果,推测其降解机理,探索环境内分泌干扰物光氧化处理的新体系,同时为预测其在环境中的光降解行为提供了依据。

Their low wages has expedited the development of these enterprises. To date, the ratio of the external employed population in the total employed population has been on the rise. And to some extend, it increased the urbanization level of Quanzhou, reducing the spatial dispersion of its in-situ urbanization. Secondly, as a source of the in-situ urbanized population in Quanzhou, up to now, the proportion of the external floating population in the total population and urban population has shown a rising trend.
迄今外来就业人口在总就业人口中的比例呈上升趋势,并在一定程度上提高了泉州的城市化水平,削弱了其就地城镇化的空间分散性;②作为泉州就地城镇化的人口来源,迄今外来流动人口在总人口和城镇人口中的比例都呈上升趋势,他们在泉州各县市的分布由于乡镇企业的发展水平差异而具有一定的规律性。

The selection of fracture splitting forceparameter mainly depends on experience and no theory can abide by.In this paper aim at the technique of fracture splitting of engine connectingrod, the materials fitting to fracture splitting have been analysed, according tosome influence factors that the former has researched. The influence that thechemistry compositions to the mechanics function and the physical function insteel have been analyzed. The theory of quasistatic fracture splitting of suitableconnecting rod for engine EA827 has been studied. Aimed at the new materialC70S6, the quasistatic procedure has been numerical simulation analyzed bySPH non-mesh method. The solved stress intensity factor module andparameterize model building module have been developed based ANSYS byAPDL.
