And this causes a frequency change Δf. The resonant point tracing algorithm describes how to detect Δf. So it can introduce a feedback frequencydifference -Δf through a closed loop to realize the resonant state o In the digitaldetection scenario, using staircase wave to replace saw tooth wave, it can overcome a lot of shortcomings in the analog system. The character of the staircase wave affects the detection precision directly. This thesis analyzes a high precision scenario producing a staircase waveform in detail. It can reduce the number of the bits in D/A converter greatly. This thesis proposes another method to improve the detection precision in case that the A/D converter has comparatively little number of bits, while this method will not increase the cost of the system greatly.

在谐振式光纤陀螺中，环形谐振腔的旋转使得谐振腔的谐振频率发生了变化，从而产生了一个与旋转速度成正比的频率变化值△f，谐振点跟踪算法描述了如何检测出△f，从而可以通过闭环在系统中引入反馈频差-△f，实现光路的谐振状态；在数字闭环检测方案中，用阶梯波作为反馈信号来代替锯齿波，可以克服原来模拟系统中锯齿波的很多缺点，阶梯波的性能直接影响着系统的测量精度，本论文详细分析了一种高精度阶梯波生成方案，使得所需D／A的位数大大降低；本文还分析了A／D转换器对系统测量精度的影响，提出了一种A／D转换器位数较少的情况下提高系统测量精度的措施，同时又不会增加太多的系统成本。

We have studied the variational pattern of track geometrical form due to wheel/rail forces under the quasi-static for operating of rolling stock, and also have studied the actions on elastic displacements of constraint rail due to the thickness and stiffness of track pad.

由轮轨力所引起的线路几何形态的变化规律；在假定轮轨力不变的情况下，又研究了轨底垫层的厚度和刚度对于约束钢轨弹性位移所起的作用；为确定轮轴的弯曲变形对轮轨关系的影响，同时建立了轮对有限元模型，计算了轮对承载状态所发生的弹性变形。

The tractate also does some research to find out how to use the in-house development system integrated with the CRM system to map the special school's business at the same time, and the integration makes the marketing process, sales process, order process, programme management process, AR process and financial process be related and relied each other.

Objective:The aims of the present study were to determine the expression of transformation growth factor β 1 (TGF β 1) mRNA and TGF β 1 protein in the peripheral blood and its relation to serum levels of procollagen type Ⅲ N terminal peptide in the patients with cirrhosis.

转化生长因子-β1(TGF-β1)在一些体外和体内的研究中均显示能刺激胶原和细胞外基质的合成，同时又可通过抑制ECM降解以加强纤维的发生，在肝纤维化中起重要作用。

The internal skin is a layer of rotate-able white translucent screens. When the screen is rotate to the position perpendicular to the facade, the panoramic lake-view enters the dining space; when closed, the dining room has both proper natural light and privacy. The glass boxes would look like white lanterns floating on the lake, as the interior lighting is softly diffused by the screen.

外层为Low-E中空玻璃幕墙，设有电动开启扇；内层为可透气的中转白色轻纱屏风，可开可闭：开启时，湖面的景色被毫无阻隔地引进室内的用餐空间；闭合时，用餐空间可拥有私密性，同时不影响采光；若在夜晚，室内的灯光通过轻纱发生漫射，水面上的玻璃盒子有如漂浮的纸灯笼。

In the early thirteenth century, King John had a bitter disagreement with Pope Innocent III about who would become Archbishop of Canterbury, and trenched on the property of the church. As a result, he was excommunicated by Pope Innocent III. Besides, King Johns tyranny led to the rebel of nobles. Suffering dual pressure, he had no choice but signed the Magna Carta. As far as its contents and nature are concerned, the Magna Carta was a typical feudal law and common law document.

十三世纪初，约翰王就坎特伯雷大主教的人选与教皇英诺森三世发生激烈冲突，还借机侵夺教会财产，结果被教皇开除教籍；同时由于约翰王的横征暴敛、穷兵黩武，导致了贵族反叛，双重冲突的巨大压力使约翰王不得不签下了《大宪章》。

According to the quantity occurred of the pests and the degree of the lawn destroyed, we have known the dominant species of the pest in the lawn. and the reason and dynamic of these species have been analyzed. It is important to the pests management of the Trifolium repens in the level of community.

同时，根据害虫的发生数量和对草坪的危害程度，从群落的角度确定了白三叶草坪上害虫的优势种，并分析了这些优势种产生的原因和动态，为白三叶草坪在群落水平上进行综合治理提供了重要的依据。

It\'s possibly that increase of hydraulic limitation with tree height influenced leaf water potential and turgor as well as leaf structure,which strengthened hydraulic limitation on leaf gas exchange characteristics including photosynthesis and transpiration rate, resultantly influenced carbon assimilation and CO_2 fractionation and increased water use efficiency and drought resistance capability.

应该是水力限制影响了叶片的水势和膨压、同时造成叶片的结构发生改变，而结构的改变加剧了水力对气体交换的限制、影响了光合碳同化以及对CO_2的分馏效应、使叶片的水分利用效率和抗旱性增强。

Objective: To verify whether hot PBS washing after the enzymatic reaction between tyramine and horseradish peroxidase can improve the sensitivity and specificity of catalyzed signal amplification. Methods: Using 7 different types of primary antibodies and 2 tomor microarray system, we carried out EnVision, LSAB, Standard CSA, and modified CSA staining sod compared their sensitivities and specificities.
