海拔

At 2 900 m altitude,incubation with adding oxygen during incubation reduced embryonic mortalities during early and later phase,and increased hatchability.

但他们都是研究较高的海拔环境，实际生产中很少在这样高的海拔进行大量的孵化生产。

It is shown that, in some areas, such as Tarim Basin, Beishan and Qaidam Basin, although the results derived from traditional Airy model and lithospheric isostasy model are close, the lithospheric isostasy model can explain the nature of the mass balance in a more reasonable way.

计算结果表明，在一些地区，如塔里木盆地、北山和柴达木盆地，尽管岩石圈均衡模型和Airy模型得到了一致的海拔值，但岩石圈均衡模型更能体现均衡过程的物理本质；除青藏高原造山带外的多数块体，岩石圈均衡模型的计算结果更接近观测海拔和地表垂直运动状态；总体上，考虑地幔岩石圈热结构影响后，中国大陆各地区的均衡结果普遍优于传统的均衡模型。

LST lapse rate in high altitude regions is higher than low altitude regions.

高海拔地区地表温度的垂直递减率要高于低海拔地区。

This is an important consideration for high altitude flights, as the air temperature drops with altitude, at an approximate lapse rate of 2 degrees Celsius per 1000 feet.

这是一个重要的考虑因素，为高海拔地区的航班，由于气温下降，与海拔高度，在一种近似失效率为2摄氏度，每1000英尺。

Thus it indicated that the growing conditions had some effects on the genetic substance of Liquidambar formosana trees when they grew in the conditions of a low altitude for a long time, and when they grew in the conditions with or without sunlight at an altitude of 700 m, although a significant difference occured in the growth of Liquidambar formosana, no obvious difference was found in genetic substance.

这说明长期低海拔的生长环境对枫香的遗传物质有一定的影响，然而在710 m海拔的不同光照条件下，虽然枫香生长表现出巨大差异，但在遗传物质方面却没有发现明显差别。

As we moved to the base camp, we simultaneously completed two ascendings. On 16 September we rose to the mountain Murat (4100 meters), on 19 September we ascended Shigar (4700 meters).

Marat只跟我们到了登山大本营，同时我们完成了两次攀登。9月16日我们登上了海拔4100米的小山Murat.9月19日我们登了海拔4700米的Shigar山。

The northern slope of Changbai Mountain where there is not only a high diversity in vegetation types and species, but also high variation of diversity pattern along the altitude gradient.

不同物种沿海拔梯度的连续或间断分布，不仅反映了环境随海拔的变化规律，同时也反映了物种的生物学、生态学特性、分布状况及对环境的适应性。

Results Morphological and organelle c CA2 and CA3 districts in the sub acute group rats.

结果 NCAM在不同海拔大鼠海马CA2区和CA3区神经细胞的胞膜上的量随海拔的升高而降低。

The region in the altitude f rom 4400 to 4600 meters , which is mainly covered by alpine meadow and alpine swamp meadow , is st rongly degraded by the stock raising with it s influence radius of about 24 kilometers. The influence distance perpendicular to roads is also 24 kilometers , since road const ruction accelerates human2induced destruction to vegetation. Vegetation in shade aspect is rising due to the increase in precipitation , while vegetation in sunny aspect tends to be stable or degraded because of the enhancement in sunlight . Furthermore , the vegetation coverage is influenced by the groundwater level . In near riverbed fields , where the depth of groundwater is shallow , plant s can easily grow ; while in far riverbed fields , vegetation is prone to degrade due to drainage. The radius of river influence is 24 kilometers.

海拔4400～4600m的较低海拔地带退化最强烈，主要为高寒草甸与高寒沼泽草甸受牧业影响较大；牧业影响半径为24km；道路的影响范围为24km，道路的修建加速了人类对高原植被的破坏作用；阳坡植被呈现趋于稳定和退化的趋势，阴坡植被表现为增长的趋势，降水量增加是源区植被，尤其是阴坡植被变好的重要原因，而太阳光照增强是导致阳坡干旱和植被趋于退化的潜在原因；近河床区地下水位埋深较浅，植被生长具有稳定的地下水源；在远离河床的一定区域内，地下水易于疏干，植被易于退化，河流影响范围为24km。

Peru and Bolivia at the junction of the Andes Puna plateau north, the lake elevation of 3,821 meters, is the world's highest navigable lake ferries.

位于秘鲁和玻利维亚交界的安第斯山脉的普纳高原北部，湖面达海拔3821米，也是世界上海拔最高的大船可通航的湖泊。

The basic concept of FOP can be summarized as to further optimize effective prescription according to the standard of curative effects and with the aid of modern science and technology and theories of traditional Chinese medicine.

其基本内涵可概括为：以确有疗效的中药复方为研究对象，以现代科学技术和传统中医药理论为技术支持，以该复方所治病证的药效响应为评价标准，以优化重组疗效更优的新复方为研究目的。

Ever since our world has been a world, native forests have been indiscriminately exploited by man.

自从我们的世界一直是世界原生森林被任意剥削人。
