The model not only provides a fast means of modeling transients in gain-clamped EDFA′s, but also shows clearly how the laser relaxation oscillation frequency, damping constant, and oscillation amplitude are affected by design parameters through explicit analytical expressions. Modeling shows quantitative agreement with experiments when the spectral-hole burning effect plays minor role on EDFA transients.

首次发现全光链路控制EDFA瞬态的WDM系统中，通过环形腔激光反馈产生的补偿信号，在系统要求的典型功率范围内就可能发生受激布里渊散射，并因此损伤系统性能。

Serrations, rings, etc. may prevent torquing the fastener to failure due to socket cam off or recess bit cam out. NOTE: The washer I.D. should not be larger than 0.04 in (1.0 mm over the major diameter of the screw.

由于套筒或内花形枪头容易滑脱出来而使紧固件无法扭断，扳拧工具上可做出锯齿形的凸起、环形等等以防止这种情况发生。

Then their structural characteristics,distribution and runnings were observed by light and scanning electron microscope.

在成牙本质细胞层下，血管网发出终末毛细血管网的动静脉分支，形成连续的环形的末端接触，构成了铸型最外部的细枝样结构。

The annular supporting excavations increase with the popularizing of rotundas and sphere buildings.

For a CW Ti: sapphire rins laser without optical diode, there are two output beams corresponding to two oppositely traveling waves in the cavity.

在连续钛宝石环形激光腔中，无光学单向器时存在相向传播的两束光波，有两个对应的输出光束。

Right hand at the top of the frame. Second, he uses a Bookwalter pediatric ring retractor system to keep the vaginal cavity open as the dissection progresses. Two retractors attached to the bottom of the ring maintain downward and lateral pressure within the cavity.

其次，Dr。 Meltzer用了Bookwalter小儿科环形牵引器系统来保持阴道张开，以利整个切割手术进行，环底附着的两个牵引器则维持了阴道向下和侧面的压力。
