In the face of these problems, the medical concept has been re-examined and re-thought. The concept of the holistic view of the unity of nature and man in traditional Chinese medicine has certain enlightenment for dealing with the problems in the current medical development. Based on the holistic view of the unity of nature and man, the overall connection between human’s heart and body and nature is explained, and the further construction of TCM psychosomatic medicine is conducive to guiding the diagnosis and treatment of clinical diseases, and providing new enlightenment for the current medical concept thinking and clinical disease research.展开更多

Marx and Engles also pointed out the duality of the conquest, change and influence exerted on nature by man. On one hand, it can improve people’s living conditions and make people free from the enslavement of the nature. On the other hand, it may also lead to excessively snatching and wrecking nature, then make the deterioration of the environment and ecology out of balance. They also, from the technical angle of ecology, put forward the concrete measures to realize the harmonious symbiosis of man and nature in the development of economy. They also believed that only when socialism or communism is realized, can the conciliation of mankind and nature be realized finally. Marx and Engle’s theory of harmonious symbiosis of man and nature is of great theoretical directive significance for us to insist on the scientific development view.展开更多

The humanity is not always there,and they come from natural world and are long-term development products of the nature. Man has the undeniable dependence on the nature,but this kind of dependence is not the negative adaptation and is that the humanity has the huge motility to the nature. It should correctly process the relation between man and nature,and realize positive cycle and coordinated development between natural ecology and human society. It has the significant theory value and the practical significance for human society's sustainable development to grasp and comprehend scientific connotation of Marx's theory of man and nature.展开更多

To illustrate this point, this paper thinks The Woman Warrior and Ballad of Eternal Sorrow are two significant texts: Ballad of Eternal Sorrow tells an ordinary, self-respecting, and life-respecting story of WANG Qi-yao and the girls like her as well as the city Shanghai. They blend into one harmonious whole: The city is like the girls and the girls match the city. Likewise, The Woman Warrior highlights the significance of naturc on the girl narrator's epiphany and healthy growth. The narrator comes to understand that paradoxes are the basic existent condition of human beings and so what she needs to do is to be magnanimous and balanceable in accepting these paradoxes.展开更多

Through technological innovation, efficiency satisfaction of unit resource can be increased; structure andfunction of eco-system can be perfected; supply capability of eco-system can be improved. To build the harmonioussociety, human should consider the reasonable distribution of limited resources from two sides. The first one is that theutilization of two functions of resource supply and pollution purification to nature should not exceed its special supplycapability formed under its special structure and function states, i.e. harmony between man and nature. The second sideis human being should think over the reasonable and effective distribution of limited resources in economic society, i.e.harmony between human beings and society. The reasonable economic activity of human being is the key to the harmo-nious development of man and nature.展开更多

To have an embedded and penetrating idea about the differences between the two cultures, it is necessary to gain sufficient knowledge of man- nature relation in dominant Chinese and Western conceptions. This paper aims to explore this issue from the perspective of Taoism and Confucianism in Chinese context, and ancient Greek and Hebraic heritage and modern mechanical view in Western tradition.展开更多

However, very scarce information on the performance of the swirl tube cyclone especially at high operating pressure emulating actual field condition was published in journals. Performance assessment was usually done at a low operating pressure using either air-water, air-fine particle mixtures or dense gas such as SF6 . This paper fills the existing gaps and reports the initial findings on the performance assessment of a horizontal swirl tube cyclone for gas-liquid separation operating at a flow rate of 5 MMSCFD at 40-60 bar operating pressure.展开更多

This paper aims to evaluate the gas-liquid separation performance of three types of cartridge filters used in the West-East natural gas transmission project. The comparison of the original pressure drop of clean filters and the evolution of pressure drop as liquid droplets deposited in the filter media are described. The original pressure drops of these filters were similar but the pressure drops at a steady state were different. Fractional efficiency was used to study the separation performance of cartridge filters. Droplets at the outlet of the filters had small diameters, no more than 3 μm, but were very numerous. The effect of filtration velocity on gas-liquid separation performance was analyzed. Higher filtration velocity indicated better gas-liquid separation performance. Finally the quality factor related to pressure drop and filtration efficiency was applied to evaluate the gas-liquid separation performance.展开更多
