The main research contents and results are given as follows:(1) Principles and characteristics of different types of polarization controllers are analyzed, the compare of the difference of these polarization controllers are discussed based on them, drawn a conclusion that the polarization controller which based on squeezing fiber and has variable delay quantity are suitable for high speed optical communication system.(2) The reset principle of the typical four channel polarization controller which is based on squeezing fiber is analyzed, and the design of its concrete reset scheme is given based on them. The reset process and the corresponding operation list are given in detail.(3) The systematical experiment is made when the typical four channel polarization controller is put into the PMD compensator. The experiment result showed that the channel which needs reset can efficiently return to the mean place, and the effect of reset was good, it didn't cause any badness infection on PMD compensation.(4) A new type optical signal time-domain depolarizer is given, and a new PMD compensate method is given based on it.

由此得出延迟量可变型光纤挤压型偏振控制器适用于高速光通信系统的结论；(2)具体分析了典型的四通道光纤挤压型偏振控制器的复位原理，并在此基础上对其进行了具体复位方案的设计，给出了各种情况下的详细复位流程和相应的复位操作列表；(3)将四通道光纤挤压型偏振控制器应用于偏振模色散补偿器中进行系统实验，实验结果表明，需要复位的通道能有效地回到中间值，复位效果良好，且复位未对PMD补偿产生不良影响；(4)设计了一种新型的光信号时域退偏器，并基于该退偏器提出了一种新型的偏振模色散补偿方法。

After this the Euclidean and hyperbolic geometries are built up axiomatically as special cases of a more general 'descriptive geometry'.

在此之后的欧几里德和双曲几何的建立作为一个更一般的'特殊情况下，公理画法几何'。

Amid the despondency, however, supply and demand are moving towards balance.

然而，在此令人失望的情况下，供需正趋于平衡。

The experimental result display system is useful with commercial webcam. The system is stable with the situation in there are no the same color as marked color in background. In clinical experiment for patients with frozen shoulder, the result display system has diacritic ability of the action of the patients. The system is the feasible evaluation tool for shoulder joint assessment.

实验结果显示，此系统适用於现市售网路摄影机，在背景色调不与辨识色重覆的情况下，以正常人测试稳定度高；临床测试中针对五十肩患者进行测试，结果显示系统有评估肩关节活动障碍程度的能力，因此本系统因适合作为评估肩关节障碍患者的辅助工具。

To help the reader over this disunity and lack of context the present translators have resorted to various devices.

为了帮助读者在此不团结和缺乏的情况下，本翻译诉诸各种设备。

The measurement reproducibi-lity of the dosimetry system was obtained by taking out of sample from the cavity.

此剂量系统的测量重复性检验是在剂量计元件每次测量信号幅值之后，从谐振腔中取出再插入的情况下进行的，其相对标准偏差为±0.83％。

Based on that a model of decision under uncertainty is established to explain decision problems when the decision maker is facing uncertainty, among which is the famous Ellsberg Paradox.

并在此基础上建立了不确定情况下的决策模型，对决策理论中著名的Ellsberg悖论做出了合理的解释。

It can be assured that the temperature of elusion of the products under the highest pressure (30000Psi) is 4～10℃, which is now the best standard in the world.

项目 市场前景由于本产品在最高压力（30000Psi）情况下能保证出样温度4～10℃，此指标具有国际领先水平，故有高的破碎率和高的活性率。

From this perspective, the dissertation propounds theoretic framework of Hainan CGE model, prepares Hainan Social Accounting Matrix integrating Hainan's statistic data, forms an equilibrious and uniform data set, and on this basis constructs a CGE model referring to Hainan's six departments to next study impact of policy changes about exemption of agricultural tax for specific produces and further reduction of agricultural tax on Hainan's economic structure, producer welfare, consumer welfare, fiscal revenue and so forth, and provide certain theory and means for enaction, analysis and evaluation of provincial policy.

本文从这个角度出发，提出了海南省CGE模型的理论框架，结合海南省统计数据的实际情况，编制出海南省社会核算矩阵，形成一个均衡一致的数据集，并在此基础上构建出一个海南省六部门的CGE模型，用于下一步研究取消农业特产税和进一步降低农业税等政策变化对海南经济结构、生产者福利、消费者福利、财政收入等方面的影响，为省级政策的制定、分析和评价提供了一定的理论和方法支撑。

If so, it will use this default as fallback if the browser preference is not available.

如果是这样的话，在浏览器偏好不可用的情况下，它就会将此默认语言作为最低限度的可用语言。

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。
