1·We have discussed that earlier when we dealt with the planets, and we dealt with uniform circular motions, and we evaluated the centripetal acceleration.
先前在讲行星时,我们讨论过这个，我们讨论的是,匀速圆周运动，而且我们评估了,向心加速度。
2·This can be called centripetal radiation.
这可称之为向心辐射。
3·We call it "centripetal acceleration."
我们称之为“向心加速度
4·So if you are 100 times further away like Pluto compared to Mercury then the gravitational... the centripetal acceleration which is due to gravity is 10,000 times smaller.
而冥王星的距离，是水星的一百倍，那么它的引力与向心加速度，均是水星的一万分之一。
5·Conclusion the cephalic vein or basilic vein in the elbow can be chosen for centripetal puncture during the early period of arteriovenous internal fistula in hemodialysis patients.
结论血液透析患者动静脉内瘘早期启用可选择肘部头静脉或贵要静脉向心方向穿刺。
