Flying at altitudes of about 7,000 meters, the photo-reconnaissance aircraft captured detailed images of mountain snowpack over a wide area. 飞行在海拔约7000米的高度,空中拍照观测机捕捉了覆盖大范围雪山积雪的精密图像。
The NASA flight will also measure how much sun is reflected from the snowpack, which can indicate how fast it is likely to melt. 美国国家航空航天局还测量多少阳光遇积雪反射回来,这能预示积雪可能多快融化。
The snowpack, an important source of water for the state during the summer, is typically at its peak this time of year. 积雪是加州夏季用水的重要来源,往年这个时段通常是积雪达到峰值的时期。
Good avalanche safety is a continuous process, including route selection and examination of the snowpack, weather conditions, and human factors. 很好地躲避雪崩,保持安全是一个连续的过程,包括选择路线、检查积雪、了解天气状况及其他人为因素。
Litter decomposition and nitrogen mineralization under snowpack were active even in winter, and nitrogen content was high with rapid mineralization. 积雪期凋落物分解和氮矿化均在进行,土壤具有很高的氮素含量及矿化速率。
All avalanches are caused by an over-burden of material, typically snowpack, that is too massive and unstable for the slope that supports it. 所有雪崩都是由于物质的过渡负荷造成,通常是积雪堆积过厚,很不稳固,超出了山坡面的承载能力。
If a ski instructor begins lecturing on snowpack composition and meteorology, he will lose his students regardless of their aptitude for skiing. 如果一个滑雪教练一开始就讲授高山生态学和气象学,学生们会跑掉,不论他们的滑雪的天分如何。

An Overview of the Researches on the Coupled Transport of Water, Heat and Solute in the Accumulating and Melting Processes of Snowpack 积雪融雪过程中水、热、溶质耦合运移规律的研究进展
A method for measuring liquid water content in the alpine temperate snowpack 山地温性积雪内液体水含量的测定方法
The "snowpack unit" is defined. Upon the new concept, the avalanche hazard evaluation is distinguished into regional avalanche hazard evaluation and site avalanche hazard evaluation. 在提出“积雪单元”概念的基础上,将雪崩危险度评价分为区域雪崩危险度评价和点位雪崩危险度评价。
The snow cover is characterized by shallow snowpack, less snow density and high evaporation rate in the winter. 气温低、雪层薄、雪层内温度梯度大,积雪密度小,雪面蒸发强是其特征。
In this paper, snowpack distribution for Tian Shan mountain is analysed. 本文对天山山区积雪分布的分析表明:山区积雪消融过程和积雪水量的分布是有一定规律的,积雪深随高度的增加可近似用线性函数表示。
If insulating snowpack is present, carbon availability also controls heterotrophic activity. 如果存在绝缘的积雪层,可溶性碳底物在自由水存在的情况下可控制异养微生物的活力。
The regional evaluation of avalanche hazard, based on dividing snowpack units, is to determine the grades of the units and mapping. 区域雪崩危险度评价是在划分积雪单元的基础上,评定各单元的等级高低并进行制图;
