On the one hand , the receiver must be self - adaptive to set as fast as possible the " 0 " and " 1 " bit level judgement threshold in a dynamic way ; on the other hand , the transmitter of onu should take some measures to minimize and compensate for the burst delay . the optical burst transmission circuit is thus required to switch on and off the laser in a snappy way to ensure fast signal sending . in that sense , the laser must be designed with a superb response speed 一方面，接收机必须具有自适应功能，能以最快的速度动态调定" 0 " 、 " 1 "比特电平判决门限；另一方面， onu的发射机应该采取-定的措施减小和补偿突发时延，其光突发发送电路要求能够非常快速地开启和关断激光器，迅速发送信号，所以，它需要使用响应速度很快的激光器。
Finally , being aimed at a certain machine model , a experiment research about the means of relief valve to reduce hydraulic impact is carried out , which prove the founded prove founded mathematics model . also , some pending coefficient are amended and the optimum pressure of relief valve is determined . at the same time , a experiment and emulation research about the means of accumulator to decrease hydraulic impact is carried put , in which the optimum pneumatic pressure and the optimum primitive capacity of accumulator were determined 最后针对某一具体机型，对用溢流阀方式减小液压冲击进行了实验研究，验证了所建立的数学模型并修正了待定系数，确定了溢流阀的最优调定压力；对用蓄能器方式减小液压冲击进行了实验和仿真研究，确定了蓄能器的最优充气压力和最优初始容积。
It showed that activated inhibition by weak noise could be gabaergic inhibition . from above the findings , we could give a hypothesis that the input of random oscillation induced by noise in the cochlea to central auditory system could be integrated in the central auditory nucleus and the response of sound - sensitive neuron to sound stimuli could be adjusted to an optimum state for signal intensity coding 根据这些变化可以推测，这种背景噪声的生物学作用可能是通过弱噪声所引起的耳蜗随机共振的输入，在上行过程中经各级听觉核团的整合，将中枢声敏感神经元调定在一种准备状态，并定型放电率函数和调制神经元对声馨硕士学位论文master ’ st砰iesis强的编码。
