双棱镜

The BPO is produced at KOMZ (Kazansky Optiko-Mekhanichesky Zavod) in the Autonomous Republic of Tatars.'B' stands for binocular,'P' for Porro prism, and 'O' stands for individual focus oculars.

BPO是位于Autonomous Republic of Tatars 的KOMZ (Kazansky Optiko-Mekhanichesky Zavod)生产的。B表示双筒望远镜，P表示保罗棱镜，O表示目镜分别调焦。

In the course of testing, the laser was used as light source with twin-light path, dispelled the error of light-intensity variation of traditional detection devices, the measurement result only relates to the relative change of optical intensity .

测量以激光为光源，采用双光路法，消除了通用检测仪由于光源光强不稳定产生的误差，使得测量结果只与光强的相对变化量有关；光波出入波导均采用棱镜耦合，减少了普通测试方法因样品质量及面形误差和端面洁净情况不同或输出透镜不能很好汇聚光波而产生的误差；利用常规仪器设备实现了数字化检测显示，避免了人为主观读数产生的误差；利用AD538实时模拟计算芯片，提高了计算精度和运算速度。

Then we make a further discussion of its applied areas including laser diode, pigtailed laser diode, laser diode arrays, different shape of inner cladding, etc.

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
