Another idea is that a connection between dark matter and dark energy would alter the growth of cosmic structures, which depends delicately on the composition of the universe, including its dark side.

另一种设想是暗物质和暗能量之间的联系会改变宇宙的结构，因为宇宙结构严重依赖于它的各种构成成分，包括黑暗部分。

By changing the composition of the semiconductor materials, it is possible to determine the amount of energy given up by each electron, and hence the light's colour.

改变半导体材料的构成可以改变电子能量释放的多少，从而改变光的颜色。

The amount of energy emitted by the Earth depends significantly on the chemical composition of the atmosphere, particularly the amount of heat-trapping greenhouse gases.

而地球向太空所辐射的能量多少，则在于大气层中空气成分构成，尤其是温室气体的含量大小。

Japan imports nearly all of its oil and natural gas consumption, and the earthquake, having wreaked havoc on select nuclear power facilities, will likely result in a sustained change in the composition of Japanese energy demand, including an increased demand for oil and some refined products.

Weather is caused by disturbances within the atmosphere, but climate is controlled by external influences, such as the distribution of oceans and continents, the extent of ice and snow-cover, variations in the amount of energy from the sun, and changes in the chemical composition of the atmosphere.

Known for his highly original approach to composition, Klein feeds off the improvisational energy of jazz, but also integrates sounds from a broad range of musical experiences.
