snow level

The existing snow-line of the glaciers varies from 3700 to 4200 m . above sea-level.

这些冰川现在的雪线由海拔3700至4200的米不等.

We used big litterbag method to study the dynamics of leaf litter decomposition in different damaged level bamboo forests in Wuyi Mountain over two years for understanding the influences of snow storm on cycle of matter and energy flow.

为了研究雪灾干扰对森林生态系统物质循环与能量流动的影响，利用大样袋网袋法对武夷山3种受灾程度毛竹林样地中的凋落物分解进行连续2年的观测研究。

The foundation of building a sporting powerhouse lies in mass-participation sports and China's hosting of the Games should entail a higher national level of winter sports, especially snow sports.

体育强国的基础在群众体育。要通过举办北京冬奥会、冬残奥会，把我国冰雪运动特别是雪上运动搞上去。

Finally, we not only ensure the randomness of the falling snow, but also guarantee the physical accuracy of the falling snow particles in macro level. Thirdly, the method of fractal and draw-line is adopted to construct three-dimensional snow.

既模拟了雪花飘动的随机性，又保证了雪花粒子的飘动在宏观上是准确的。再次，采用分形画线的方法，构造出三维的雪花。
