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。

WD40 domain, found in a number of eukaryotic proteins that cover a wide variety of functions including adaptor/regulatory modules in signal transduction, pre-mRNA processing and cytoskeleton assembly; typically contains a GH dipeptide 11-24 residues from its N-terminus and the WD dipeptide at its C-terminus and is 40 residues long, hence the name WD40; between GH and WD lies a conserved core; serves as a stable propeller-like platform to which proteins can bind either stably or reversibly; forms a propeller-like structure with several blades where each blade is composed of a four-stranded anti-parallel b-sheet; instances with few detectable copies are hypothesized to form larger structures by dimerization; each WD40 sequence repeat forms the first three strands of one blade and the last strand in the next blade; the last C-terminal WD40 repeat completes the blade structure of the first WD40 repeat to create the closed ring propeller-structure; residues on the top and bottom surface of the propeller are proposed to coordinate interactions with other proteins and/or small ligands; 7 copies of the repeat are present in this alignment.

The results implied that NO/ROS-induced ABA accumulation come from de novo synthesis pathway rather than degration of conjugated forms. The protein synthesis inhibitor actidone blocked the NO-induced ABA accumulation while having no effects on ROS-induced ABA accumulation, indicating that the action of NO was gene-expression dependent and that of ROS was gene-expression independent. These results suggested that NO may serve as a stress signal in the regulation of ABA-biosynthesis and ROS may serve as substrate in ABA biosynthesis or be involved in the regulation of enzyme activities.

1ABA合成抑制剂fluridone抑制ROS和NO诱导的ABA积累，表明NO／ROS诱导的ABA积累来源于ABA的从新合成而不是已有结合态ABA的代谢；(2)蛋白质合成抑制剂环己亚胺可以抑制NO诱导的ABA积累而对ROS诱导的ABA积累没有影响，说明NO的作用涉及基因表达而ROS的作用与基因表达无关，暗示NO的作用方式可能是作为一种干旱胁迫信号物质参与ABA合成的调节，而ROS则可能参与了相关酶活性的调节或直接参与了ABA合成的底物反应。
