For the purpose of reliable transmission, the system margin is increased blindly through enhancing the transmitter power or the antenna gain in link design.
为了使数据可靠地传输，链路设计中往往盲目加大发射机功率，提高天线增益来提高系统的余量。
2
Because of leverage, the gain or loss may be greater than the initial margin deposit.
由于杠杆的原因，获利或亏损有可能高于投入的保证金。
3
This design is the use of leading correction principle, finally meet the performance index of a control system open loop gain, phase margin, angular frequency requirements.
