例句與造句

1. This electromagnet releases a gravity lever onto the escapement above the master pendulum.
2. In the process, the gravity lever gives a tiny impulse to the master pendulum, which keeps that pendulum swinging.
3. The slave pendulum was attached to the timekeeping mechanisms of the clock, leaving the master pendulum virtually free of external disturbances.
4. A fraction of a second later ( but exactly every 30 seconds ), the motion of the master pendulum releases the gravity lever to fall farther.
5. Networks of electric clocks connected by wires to a precision master pendulum clock began to be used in institutions like factories, offices, and schools around 1900.
6. It's difficult to find master pendulum in a sentence. 用master pendulum造句挺難的
7. Shortt clocks kept time with two pendulums, a master pendulum swinging in a vacuum tank and a slave pendulum in a separate clock, which was synchronized to the master by an electric circuit and electromagnets.
8. The advantages of the Shortt clock are first, it reduced the disturbance of the master pendulum due to the impulse by only giving the pendulums an impulse once every 30 seconds exactly ( 30 pendulum swings ), and second, it eliminated all other interaction with the master pendulum by generating the necessary precise timing signal to control the slave clock ( and record the passage of time ) from the impulse mechanism itself, leaving the pendulum to swing " free " of interference.
