地球自转 [天] earth rotation
[天] rotation of the earth
- 该机构从全球各地收集地球自转的测量值,并取其平均数。
It collects and averages measurements of the Earth's rotation from around the world. - 然后将这几级火箭运送到在中国很南面的发射现场,因为在那里可以利用地球自转的优点,把它的装运能力增加到最大程度。
The rocket stages would then be shipped to the launch site in the very south of China, where it could take advantage of the Earth rotation to maximise its cargo capabilities. - 研究人员计算出这会怎样影响整个地球自转速度,这有助于保持角动量守恒。
The researchers calculated how this would affect the rotation rate of the whole planet, which would compensate to conserve angular momentum.
