Single-longitudinal-mode laser output can be realized by employing a Fabry-Perot filter and a saturable-absorber-based autotracking filter composed of an unpumped EDF and an optical reflector.

而本S频段的单模光纤回路型雷射是利用一个S频段的EDFA模组、一个光纤式法布里－珀罗（Fabry-Perot）可调滤波器、一段尚未泵激且较短的 EDF及一个反射镜所组成。

It was found that PLZT was easily reduced and the thickness of reduced layer had a linear relationship with the reduction time; The optimal conditions for PLZT were determined to be 950℃ for 1~5 hours; Reduced PLZT was composed of reduced and unreduced layer obviously and the reduced layer was transgranularly fractured while the unreduced ceramic was intergranularly fractured; Metallic lead and refractor oxides (PbO, ZrO2, TiO2, etc.) were found in the reduced layer, however, the crystal structure of PLZT was not found.

研究表明，PLZT具有较好的还原性能，还原层厚度与时间有线性关係，理想的还原条件为：950℃保温1~1.5h；还原样品有明显的分层结构，还原层表现出穿晶断裂而未还原层则是沿晶断裂的特徵；还原层主要由金属Pb及PbO， ZrO2， TiO2等氧化物组成，原先的晶体结构已不存在。

On the ground of analysis of some flaws of recent studies on unsignalized intersection,the paper bases on the gap acceptance theory ,sets up the waiting delay formula of mixed traffic flow composed of two representative types of vehicles at an unsignalized intersection,then analyzes the relation be.

本文在分析了目前无信号交叉口延误研究方法存在某些不足的基础之上，以可接受间隙理论为基础，建立了无信号交叉口大小两种车型构成的次要车流的等待延误公式。

The reason for inelastic deformation of unvulcanized rubber can be found in its chemical structure: rubber is composed of long polymer chains.

The flowfield and performance of a centrifugal compressor was predicted and analysed, which was composed of a Krain's impeller and two types of vaneless diffuser specially: one was constant area vaneless diffuser and the other was the straight-wall. The results show that the efficiency of the straight-wall vaneless diffuser is obviously lower than that of the constant area, and a separate flow occurs nearby the exit of the centrifugal impeller with the straight-wall diffuser. However, the type of vaneless diffuser has little influence on the aerodynamics performance of the centrifugal impeller. Finally, it is suggested that the constant-area vaneless diffuser should be selected as the downstream extended area of the centrifugal impeller during the prediction for the centrifugal impeller.

对Krain叶轮后带等面积与直壁两种形式的无叶扩压器离心压缩机内部流场进行了计算与分析，结果表明：直壁型无叶扩压器离心压缩机的效率低于等面积无叶扩压器离心压缩机的效率；直壁型无叶扩压器使得叶轮出口的流动出现分离；扩压器的形式对离心叶轮的整体气动性能影响并不大；在进行离心叶轮数值研究时，叶轮后的延伸区最好采用等面积无叶扩压器，以尽量减小无叶扩压器所引起的计算误差。

By mineralogical analysis of Jidong magnetite concentrates what can be found is that: It is mainly composed of magnetite, concentrate grain is medium-coarse granular crystal texture, the most is subidiomorphic or xenomorphic, is chevron and granulated, surface of the concentrate is smooth, minority of concentrate has inclusion or intergrowth, grain inch normally is 0.05~0.16mm, there is incompletely cleavage in concentrate grain.

矿相分析表明：冀东磁铁精矿粉以磁铁矿为主，矿粉颗粒为中粗粒变晶结构，多为半自形或他形，呈尖棱碎粒状，其表面光洁平滑，少数有包裹体或连生体，粒径一般为0.05～0.16mm，矿粒存在不完全解理。

Moreover, since both the CSF-box and the octamer are indispensible for LPS-induced G-CSF promoter activity, there might be a coactivation mechanism composed of Oct-2 and NF-κB for G-CSF transcription. However, the mechanism is not yet understood and deserves further investigations.

此外，既然CSF-box以及octamer对G-CSF的启动子活性缺一不可，那麼Oct-2和NF-κB之间可能存在著某种共同调控G-CSF表现的机制，尚待进一步厘清。
