Nonrenewable resources exist in a fixed quantity or stock in the earth's crust.

不可再生资源中存在一个固定的数量或库存在地壳。

I can't live in fear of the possibility that as the earth's population grows and we use up more and more of our nonrenewable resources, our children may have to lead poorer lives.

我不能总是生活在对这种可能性的忧虑中：由于地球上的人口的不断增长，由于我们正在消耗掉越来越多的非再生资源，我们的孩子可能不得不过着更加贫穷的生活。

I can't live in fear of the possibility that as the earth's population grows and we use more and more of our nonrenewable resources,our children may have to lead poorer lives.

我不能总是生活在对这种可能性的忧虑中：由于地球上人口的不断增长，由于我们正在消耗掉越来越多的非再生资源，我们的孩子可能不得不过着更加贫穷的生活。

The Earth's surface was again normal, as if nothing had happened.

地球表面回复了正常，好像没发生过什麼事一样。

The change of oblateness in individual geological periods is needed to determine the change of the earth's shape.

为了确定地球形状的变化需要了解各个地质历史时期其扁率的变化。

In this paper, we discuss the effect of the Earth's oblateness and ionosphere on the retrieval, and analyze the result of the local curvature correction and the ionosphere calibration.

本文采用模拟的方法，分析其中地球扁率及电离层对反演结果的影响，并讨论局部圆弧修正及电离层修正的效果。

Some factors such as the Earth's oblateness, the ionospheric dalay, the large-scale horizontal refractive index gradients in the atmosphere, and atmospheric multipath can influence the precision of retrieval.

地球扁率、电离层传播时间延迟、大气大尺度水平梯度、多路径传播现象等因素在某些高度范围影响大气反演的精度。

The system state transition matrix is deduced, so the zero effort miss of the interceptor can he solved with numerical method under considering the earth's oblateness effect of J2. In order to make the thrust direction change smoothly and make the zero effort miss decrease quickly, the engine thrust is decomposed along the line of sight direction and perpendicular to the line of sight direction, and the distribution proportion coefficient is designed based on the required velocity gain normal to the line of the sight.

推导了系统状态转移矩阵，通过数值方法求解得到考虑地球扁率J2摄动项的拦截器零控脱靶状态，在此基础上将推力分解到视线方向和垂直视线方向，并根据垂直视线方向需要速度增量大小设计了推力分配比例系数，使得推力方向平稳变化且能快速减小系统的零控脱靶量。

Climate in the early Pleistocene1 varied with a period of 41 kyr and was related to variations in Earth's obliquity.

过去300万年是一个气候剧变的时期，地球上的状况在寒冷的冰川期和温暖的间冰期两个极端之间交替。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.
