Roscopic survey technology uses dynamical tuning velocity gyro to measure the angular speed component of earth rotation; the quartz accelerometer measures the acceleration component of earth, the dip angle, azimuth angle, instrument side angle and some other parameters of well bore are calculated.

陀螺测斜技术以动力调谐速率陀螺测量地球自转角速率分量和石英加速计测量地球加速度分量为基础，经计算得出井筒的倾斜角、方位角、工具面角等参数。

Finally, applications of the anomalous propagation of microwave in tropospheric ducts are discussed: in connection with concrete radar parameters, effects of ducts on radar range and detection performance are discussed, the results obtained are of great value for the overall design of radar systems; by use of the interference standards of ITU-R, the co-ordination area of satellite earth-station under tropospheric ducts environment is studied ; by explaining the relationship between evaporation duct and advection fog, a new way to forecast sea advection fog from evaporation duct is provided.

最后讨论了对流层大气波导环境下电波异常传播特性的应用：结合具体的雷达系统参数，模拟计算了大气波导对雷达作用距离及发现概率的影响，对雷达系统的总体设计具有重要的参考价值；对表面大气波导环境下的卫星地球站通信协调区域进行了确定，从理论上很好地给出了协调距离量级的概念，为卫星地球站与地面微波站之间的协调提供了依据和参考；分析了利用海面蒸发波导来快速预测平流海雾的新方法，完善了平流海雾的预报方法，对海上安全作业和生产具有重要的意义。

"If people disregard the great works of the past, it is because these works no longer answer the needs of the present." 190."As long as people in a society are hungry or out of work or lack the basic skills needed to survive, the use of public resources to support the arts is inappropriate -- and, perhaps, even cruel -- when one considers all the potential uses of such money."

技术进步使人们的生活质量提高，医疗水平提高，使我们的精神生活丰富网络技术人类生产力提高，与自然作斗争越来越有优势，使我们有可能再一次又一次的自然灾难中幸存，一个最简单的例子，如果在地球的生命结束之前，人类找到延长地球生命的方法或者移民岛外星球，任何血肉之躯将抵挡不住。

On the other hand, if you mean duration of existence as an earth feature, then the Appalachians certainly are among the timeless landscapes of the world.

另一方面，如果你把存在期间看作是地球的特征，那么，阿帕拉契山无疑是这地球上的永恒景观之一。

Instead, the apparent backwards or retrograde motion with respect to the background stars is a reflection of the motion of the Earth itself.

火星逆行能在地球每次赶上和超越火星时看到，因为地球离太阳比较近，在轨道上运行的速率比火星快。

The origin of life is still a poorly understood process, but it is thought to have occurred about 3.9 to 3.5 billion years ago during the hadean or archean eons on a primordial earth that had a substantially different environment than is found at present.

对于生命起源，我们仍知之甚少，但是据猜测生命起源于距今35亿年到39亿年前，原始地球的冥古代或太古代，当时地球上的环境跟现在大不相同。

The earth satellite is an artificial object in speed, which revolves around the earth following a specific orbit.

地球的卫星是一个人造物体的速度，它围绕地球轨道后，具体的。

That ashen glow is earthshine – sunlight that's reflected from Earth and back to the moon.

那淡淡的光就是地球的反照——日光从地球发射到月球的光。

As a result of mankind's development,kinds of burden have already exceeded assimilative capacity of our environment. The environmental problem has been an international issue.

由於人类过度的开发，产生的环境负荷远超过环境的涵容能力，致使地球环境日益恶化，因此地球环境问题成为国际间重视的课题。

As a result of mankind's development, the number of burdens on the environment has already exceeded the environment's assimilative capacity.

由於人类过度的开发，致使地球环境日益恶化，因此地球环境问题成为国际间重视的课题。

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.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
