林线

As the basilisk in his chamber was connected to the Slytherin line, he collected some of its blood.

由于蜥蜴在他的分庭连接到斯莱特林线，他收集了一些血液。

They mark the tree line of our planet and the start of the boreal forest.

他们标示出地球上的林线也就是针叶林的开始

We reminded Buffett of the old play on the Kipling lines: If you can keep your head when all about you are losing theirs … maybe they know something you don't.

"我们提醒巴菲特老打吉卜林线："如果你能保持你的脑袋时，你正在失去他们。。。也许他们知道你不知道。

Based on synthetically analysis of ecological characteristics and dispersal of spruce pollen, the abundance of Picea is influenced by treeline moving upward, valley wind and glacier ablation.

通过对云杉属生态习性、传播特性等综合分析，认为剖面中的云杉丰值可能与林线上移、山谷风搬运以及冰川退缩等有一定的相关性。

The changing climate first affects the structure of alpine timberline at an autecological level, and further affects the movement of the timberline as a whole.

气候变化首先从个体的水平影响林线的内部结构，然后才影响到作为整体的林线的推移，因此研究乔木个体生理活动与气候条件之间的关系，对于研究高山林线对气候变化的响应具有重要意义。

The results showed that: 1 The survival curve of the population conformed to the type of Deevey-Ⅲ; 2 With an increase in the population mortality ratio and a decrease in the survival rate, the mortality ratio greatly increased in ages 0-40 years, reaching 89.7%; 3 There existed two peaks of mortality in the lifespan, one was from seedlings to young trees (0-40 years) and the other in the adult stage (180 years).

结果表明：1岷江上游林线地段岷江冷杉种群存活曲线趋於Deevey-Ⅲ型。2林线地段岷江冷杉种群生存率呈单调下降趋势，生存率下降趋势前期高於后期，说明岷江冷杉种群幼苗死亡率高，种群后期比较稳定。3林线地段岷江冷杉林整个生长期中出现了两个死亡高峰期，一个出现在幼苗向幼树过渡时期（0~40年），另一个出现在中龄时期（180年）。

The individual density was 4.77 inds. per gram dry soil. The results indicated that the number of soil nematode fluctuated significantly with season, the number of soil nematode in autumn is significantly more than that in summer and in spring. Shannon-Wiener index, Pielou index, Margalef index and Trophic diversity index were used in analyzing the diversity of nematode community, ranking Cc＞Pm＞Clc, while Simpson index ranking Pm＞Clc＞Cc. The value of f/b, MI index, PPI index, MMI index, MI2-5 index, SI index and EI index were used in analyzing the characteristics of the functional structure of the nematode communities, ranking Cc＞Pm＞Clc, while PPI/MI value ranking Clc＞Pm＞Cc. It showed that the Clc was disturbed significantly.

研究结果表明，土壤线虫数量存在明显的季节波动，秋季明显高于夏季和春季；土壤线虫群落多样性指数、均匀度指数、丰富度指数和营养类群指数大小依次为阔叶林、针叶林和混交林，而优势度指数却表现为：针叶林＞混交林＞阔叶林；土壤线虫群落营养类群f/b值、MI 指数、PPI 指数、MMI指数、MI2-5指数、SI指数和EI指数均表现为：阔叶林＞针叶林＞混交林，而PPI/MI指数则表现为：混交林＞针叶林＞阔叶林，表明混交林受干扰明显；土壤理化特征与线虫数量、属数、生态指数间也存在明显相关关系。

Berberis wilsonae and Caragana erinacea are the species representative of retrogressive succession of the community, and the association between one of them and other species is the most insignificant among all pairs.

在岷江上游林线附近的林草交错区，该群落常常占据阳坡或半阳坡形成疏林，并和位于阴坡的云冷杉林一起形成两大具有特色的森林群落类型。

The alpine belt is the temperature-driven treeless region between the timberline and the snowline.

高山带是指自然气候森林边界即林线到雪线之间的无林区域。

Biology living or growing above the timber line .

生活或者生长在林线以上。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
