Mainly depend on the current human society of non-renewable fossil energy sources, such as coal and oil, its increasing demand. Gradually reduce the reserves, the contradiction between supply and demand becoming increasingly prominent. With the process of human history has moved forward with the depletion of fossil energy will eventually be unable to sustainable use. The total hydropower resources are limited, but it is renewable, clean energy, its energy is infinite. Therefore, the full use of limited water resources and slow down the depletion of fossil energy process, is to improve and protect the earth’s ecology and environment, one of the most realistic measures. 展开更多

Herein an estimation is given to the efficiency of nuclear explosive devices in a space-rocket complex to withdraw Hazardous Space Objects (HS0)-asteroids and cometary nuclei from the trajectories leading to their dangerous entry to the atmosphere and falling to the Earth. A conceptual choice of parameters and schemes of application of nuclear explosive devices in impact modules of space-rocket complexes to ensure asteroidal-cometary safety was made. 展开更多

WHEN Beijing has a day with pristine blue skies, it trends immediately on Wechat (China’s premier social media app). The rare occurrence of “Beijing Blue” and media chatter about such rare weather is indicative of the Chinese capital’s ongoing battle with polluted air and is symbolic of the severe pressure the country faces in the feld of environmental protection. 展开更多

Practically,the load currents in three phases are asymmetric in the power system.It means that the impedances are different in all three phases.If the consumer’s transformer neutral cut off and/or was disconnected from the neutral of power supply source,then there will be some trouble and failure occurred.The current in the neutral wire drops down to zero when the neutral wire is cut off and the phase currents of all three-phase equal to each other since there was no return wire.The currents are equal but the voltages at the phase consumers are different.Especially for residential single-phase consumers,the voltage at the consumers of the phase varies differently for three phase systems when the neutral wire was disconnected at consumer side and even the voltage at the consumers one or two of those three phases becomes over nominal voltage or reaches nearly line voltage.In this case,the electronic appliances in that phase will be fed by high voltage than the rated value and they can be broken down.In the power system of UB(Ulaanbaatar)city,there are some occasional such kind of failures every year.Obviously,many electronic appliances were broken down due to high voltage and the electricity utility companies respond for service charge of damaged parts. 展开更多

Faced with many problems (practically insoluble) that call them politicians lie (to save their careers), claiming that they are resolutely interested to earth’s environment protection. Unnecessary (for some) and outrageously expensive (for others) organization of COP21 is part of this logic of distracting the “international community” by (for example) making believe that the reduction of CO<sub>2</sub> emissions is something reachable for humans and that this reduction can weaken the harmful effects of global warming such as: floods, endless droughts, melting glaciers, upsurge of hurricanes or tornadoes, etc. Can the “binding” commitments taken during COP21 be effective? Our objective and immediate answer is: No. Because those who have made commitments, ignore completely how the CO<sub>2</sub> (main object of their attentions) or sulfur dioxide (SO<sub>2</sub>) behave with respect to some predominant elements of the atmosphere such as clouds. Moreover, a significant number of the propaganda forums’ stakeholders ignores that earth’s atmosphere is considerably affected by the radiation from the sun and that the intensity of solar radiation received at the surface of the earth mainly depends on the Earth-Sun distance and the precession angle of the earth relative to its orbit. Earth-Sun distance and precession angle of the Earth’s orbit vary in space and time: this Physical law must be constantly present in our minds. Teaching the fundamentals of Atmospheric Physics allows solar radiation and its derivative forms (e.g.: winds, snow or rains) to cease to be a mystery in the mind of the international community. 展开更多

This paper expounds the consideration to the design of protection and exhibition of Hanyuan Hall and Linde Hall of the Daming Palace. Based on in-depth study on their existing conditions after archeological excavation, and in combination with comprehensive considerations in terms of the protection of the main body of sites, the restoration research of existing bases and superstructures, the requirement of site open exhibition, etc., it proposes the design to restore the rammed earth bases by surrounding them with bricks and stones or rammed earth. Besides the protection and exhibition of the site of Hanyuan Hall bases, it also integrates the features of landform there to design the protection and exhibition of brick and tile kiln of Tang Dynasty within the relic area. Under the condition at that time, a semi-underground small exhibition center is designed by taking advantage of the height difference of base side slopes, satisfying the requirement of exhibition, and meanwhile preserving the overall landscape of the site. The integration of the design of protection project with archeology as well as the science and technology of heritage preservation is a brand-new probe into site protection design. 展开更多
