Along this transect the rise in elevation is gradual . 沿着这条植被带海拔上升舒缓。
3.
Elevational and latitudinal trends were not pronounced . 海拔和纬度的变化趋势不明显。
4.
The density varies with the temperature, and g with the latitude and elevation above sea level . 但密度是随温度变化的，而g则随海拔高度和地理纬度变化。

Callaham and liddicoet found an elevational cline in ponderosa pine from northern california . 卡拉汉和利狄柯特发现加利福尼亚北部产的黄松有一海拔渐变群。

At one point at an elevation of about 5500 feet above sea level the students pick up dozens of marine fossils . 学生们在海拔约5500英尺高度的地方，采集到了几十种海底化石。
7.
When one comes to more tractable land at lower altitudes, problems of permanent pasture improvement are not nearly so difficult . 在海拔较低的易于耕作的土地上，改进永久草场的问题并不很困难。
8.
It is customary to fly, so far as is feasible, at a uniform elevation above sea level but within a range of 750 to 1500 ft above the earth's surface . 在条件许可之下，一般都在海拔以上离地面750到1500英尺范围内的均匀高度上飞行。
9.
We have no evidence of what would happen if transfers were made between high elevational regions but vastly different day-length regimes . 假如引种是在热带高海拔地区之间进行，只是日照长短的系统有很大改变，究竟会有什么情况发生，现在还没有证据。
