In areas of heavy snowfall, for example, the pitch is steep to prevent the accumulation of snow on the roof, snow that might eventually find its way into the house as it melts.
例如，多雪地区的斜坡陡，目的是要防止屋顶积雪或最终融化时有可能流人屋内。
As each year's snow accumulation lay on the surface, evaporation and melting caused the snowflakes slowly to lose their feathery points and become tiny grains of ice.
由于每年的雪花积累在表面之上，蒸发和融化使得雪花慢慢失去其羽状尖端而变成微小的冰粒。
The load combination is complex with consideration of the effect of asymmetry distribution of live load, snow accumulation and horizontal seismic load.
且考虑了屋面活载不均匀效应、雪压堆积效应和水平地震作用的影响，荷载组合复杂。
More snow falls there than evaporates, leading to a net accumulation of ice.
那里降下的雪比蒸发的多，使冰可以逐渐累积。
A huge mass of ice slowly flowing over a land mass, formed from compacted snow in an area where snow accumulation exceeds melting and sublimation.
巨大的冰块(由于一个地区雪的积累量超出了融化和升华量而形成的结实的雪形成)在巨大的地上慢慢滑动而形成。
One factor could be deposits of dust and black carbon (collectively called aerosols) upon the snow, which, up to an accumulation of 400 grams per square meter sharply raises the rate of melting.
雪上尘埃和黑炭（统称为气溶胶）覆层可能是其中一个因素：当覆层的积累达到每平方米400克的时候，会急剧加快融化的速度；
Linear regression analysis indicated that most of the variance in annual ionic fluxes can be explained by a linear dependence on snow accumulation rate.
线性回归分析表明，在每年的离子通量的差异可以解释成线性关系，积累率。
