Simulation of energy and water balan 篇1
Simulation of energy and water balance in Soil-Vegetation- Atmosphere Transfer system in the mountain area of Heihe Rive
In the mountain area of inland Heihe River Basin at Hexi Corridor of northwest China during the vegetation growing season from May to September, the Simultaneous Heat and Water (SHAW) model of Soil-Vegetation-Atmosphere Transfer (SVAT) system is applied to simulating and studying energy and water balance of the soil-residue-plant canopy layers in the Picea crassifolia forest and the grassland by the forest at the shaded slope and the grassland at the sun-facing slope. The simulation of energy balance indicates that net radiation of the grassland at the sun-facing slope is more than that of the Picea crassifolia forest and the grassland by the forest at the shaded slope. The energy outgoing components are the first latent heat and next sensible heat from the grassland both at the shaded slope and the sun-facing slope, but those at the former are less. The energy outgoing components are the first sensible heat and next latent heat from the Picea crassifolia forest. The composition and distribution of energy in the soil-residue-plant canopy layers in the Picea crassifolia forest and the grassland by the forest at the shaded slope make the soil layer receive less energy, which therefore, especially the forest possesses the energy conditions for soil water conservation. The simulation of water balance indicates that the water loss of the grassland at the sun-facing slope is mainly caused by soil evaporation, while evapotranspiration of the Picea crassifolia forest and the grassland by the forest at the shaded slope is less than that of the grassland at the sun-facing slope. Half of the evapotranspiration of the Picea crassifolia forest and the grassland by the forest at the shaded slope is consumed by transpiration. After precipitation, the soil water storage is increased much more for the Picea crassifolia forest and also more for the grassland by the forest at the shaded slope. Therefore the shaded slope vegetation, especially the forest is favorable for soil water storage.

Save the Energy Resources节约能源作文
Another round of energy crisis is knocking at the door. In , world oil consumption reached a new record, causing oil price in the international market to skyrocket amazingly. As for China, it was reported that many traditional mineral cities in northeastern China had run into predicament, with their economy collapsed and workers unemployed, only because coal had been mined out.
Fossil energy resources, including coal, oil and gas, are unlike sunlight, water power and wind power which are generated consistently. They re not practically reproductive during human history. Once consumed, they re gone forever. If they were to be exhausted before we could find sufficient reproductive resources to replace them with, we d have to live in entire blackout again like our ancestors have done thousands of years ago. That s of course not what anyone would want to see. Due to technical limitations, people still have to utilize these resources now.
As a result, we must economize them most cleverly. New techniques should be developed and applied to reduce energy cost in industry and daily life. Alternative energy should be employed wherever possible. Eradicate any practice that wastes energy. Humans have overcome so many crises in history, and we re sure to win this time also.

摘要：Traditionally, Chinese people regard Jiangsu as a rich area with long-lasting elegant culture manifested with typical picture of small bridge, flowing brook and graceful young lady. However, it is not the whole picture. “We Jiangsu province is divided into two parts: north Jiangsu and south Jiangsu” said Miss Xu who denied to show name and her hometown is Suzhou city, where the art ot gardening is worldwide renown, when I was a little girl, my mom always scared me with the words that don't cry, Jiangbei (short term for North Jiangsu) Wideman will catch you, and I would stop crying. Actually, it has the same effect with the big wolf will come.“作 者：Guo Liqin 作者单位： 期 刊：中国对外贸易（英文版） Journal：CHINA'S FOREIGN TRADE 年，卷(期)：, ”“(2) 分类号：Energy 篇4
Energy
As we all know we need energy in our daily life. There are many kinds of energy. We can get our energy from food.
The energy in food comes from sunlight which helps plants grow. Plants store up energy from the sun, much of our food comes from plants. Some of our food comes from animals, but animals depend on plants for food too.

The source of Energy 篇6
The source of Energy
A summary of the physical and chemical nature of life must begin, not on the Earth, but in the Sun; in fact, at the Sun's very center. It is here that is to be found the source of the energy that the Sun constantly pours out into space as light and heat. This energy is librated at the center of the Sun as billions upon billions of nuclei of hydrogen atoms collide with each other and fuse together to form nuclei of helium, and in doing so, release some of the energy that is stored in the nuclei of atoms. The output of light and heat of the Sun requires that some 600 million tons of hydrogen be converted into helium in the Sun every second. This the Sun has been doing for several thousands of millions of year.
The nuclear energy is released at the Sun's center as high-energy gamma radiation, a form of electromagnetic radiation like light and radio waves, only of very much shorter wavelength. This gamma radiation is absorbed by atoms inside the Sun to be reemitted at slightly longer wavelengths. This radiation , in its turn is absorbed and reemitted. As the energy filters through the layers of the solar interior, it passes through the X-ray part of the spectrum eventually becoming light. At this stage, it has reached what we call the solar surface, and can escape into space without being absorbed further by solar atoms. A very small fraction of the Sun's light and heat is emitted in such directions that after passing unhindered through interplanetary space, it hits the Earth.
