The invention discloses a passive optical network signal monitoring method comprising the following steps: obtaining a PON signal from one side of an optical line terminal and an optical network unit, detecting the photoelectric property parameter of the obtained PON signal and judging whether the detected photoelectric property parameter lower than a predeterminate photoelectric property parameter threshold or not, if it is, a corresponding alarming signal is transmitted to the OLT.

本发明公开了一种无源光网络信号监控方法，包括以下步骤：获取来自光线路终端和光网络单元中一侧的PON信号，检测所获取的PON信号的光电性能参数；和判断所检测出的光电性能参数是否低于预设的光电性能参数阈值，如果是，则发送对应设置的告警信号给所述OLT。

By thermally bonding the YAG crystal with 2 mm thick Nd∶YAG crystal,the Porro prism supplies multi-functions such as laser amplification,closuring the light path,polarization sensitivity to the 946 nm and so on.

直角棱镜由无掺杂的YAG晶体和2 mm厚的Nd∶YAG晶体热键合形成，可提供激光增益、光路闭合及对946 nm激光起偏等多种复合功能。角锥棱镜由熔融石英材料构成，在环形永磁铁作用下，提供法拉第旋转作用。

Remember, too, that once you go ahead with a consolidation deal there is no reverse gear, and so it's vital that you do your research and make sure consolidation is the best way forward for you.

记住，一旦你进行了加固处理并无反向齿轮所以重要的是你和你的研究整理清楚你是最好的路。

Results 84 cases were followed up for 16.7±2.3 months. JOA scores were improved from 7.3±1.7 to 16.2±0.8 (P.05), and the improving rate was 91.8%; Nurick grading were from 2.8±1.2 to 0.7±0.8 (P.05). Based on roentgenograph, no looseness, displacement, dislocation or subsidence of bone graft and internal fixator was found.

术后JOA评分从术前(7.3± 1.7)分提高到了(16.2±0.8)分(P.05)，改善率为91.8%；Nurick分级从术前的(2.8±1.2)级改善到术后的(0.7±0.8)级(P.05)。X线检查证实前路植骨块及其内固定材料无松动、移位、脱落、下沉。
