该路径长度约腔是仔细监测和调整,以便它是一个完整的倍数的峰值功率激光波长。
The path length around the cavity is carefully monitored and adjusted so that it is an integral multiple of the peak power laser wavelength.
适当增加铁心长度可以有效提高电机效率和功率因数,但会导致启动转矩倍数和最大转矩倍数减小。
Increasing core length properly can raise motor efficiency and power factor, but it will reduce locked-rotor torque ratio and breakdown torque ratio.
