Directions: Use the word in the brackets to form an appropriate phrase you have learned in 7.1. and complete the sentence with it.He was well _____ in all branches of the field and published extensively. (verse)

Shang Yang implemented a series of measures to strengthen the power of the state including establishing the Well-field System.

The type of field generated by a DC tacho-generator is A: pulsating magnetic field B: static field C: rotating field D: do not need field

What can be said about the field A: The field is left unplanted. B: The field is lying waste. C: The field is left open to playing. D: The field is played with this year,

The curl equation [img=154x44]1803a2a153c85f5.png[/img]shows that : A: The time-varying magnetic field can generate an electric field, in which the elecric field lines is closed around the magnetic field line. B: The time-varying magnetic field can generate a magneitc field, in which the magnetic field lines is closed around the electric field line. C: The magnetic field lines is closed themselves. D: Flux continuity

The Well-field System is essentially private ownership of land in Chinese ancient society because it achieved partly the dream of “land to the tiller”.( )

场论可以分为classic field theory和quantum field theory
