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。

When there is plenty of rope available, the following method illustrated in Figure 20-3 is most secure. The best river man goes first belayed by the second best who goes last. When A gets across, he moves upstream and sets upa belay opposite B. and the next wader ties in at B. Then C pendulums across taking about the same path as A. while B lets rope out, and A keeps the rope taut. If C falls, he should be pendulumed to the most favorable bank (hopefully to A so that the crossing is accomplished).

The action of page headline is self-evident, the rank that searching engine gave caption very great weight in the mechanism, look in me a successful caption should have these a few kinds of features: A, true the clou that mirrorred page article, caption and content write a law abhorrently is wrong apparently, it can let you lose the faith that searchs engine, also can let more caller prediction of a person's luck in a given year drop likewise. On the B, foundation in A, beautiful idea designs a more absorbing caption, a headline that contains window often searchs the webpage before the result to have taller hit in you than the platoon, as this hit rise, your rank also can be alled alone by search engine place takes seriously slowly, this kind of phenomenon once was in the article of President SEO (the imitate of the soft costal region of Baidu and Baidu place ignore is searched) in had mentioned. C, reasonable keyword density, avoid by all means does not pile up again in caption keyword, this kind of method already too pediatric.

页面标题的作用不言而喻，在搜索引擎的排名机制中给予了标题很大的权重，在我看来一个成功的标题应该具有这几种特征：A、真实反映了页面文章的中心思想，标题和内容不一致的写法显然是错误的，它会让你失去搜索引擎的信任，同样也会让更多的访客流失掉。B、在A的基础上，花心思设计一个更加吸引人的标题，一个含有亮点的标题往往比排在你搜索结果前面的网页有更高的点击率，随着这个点击率的提高，你的排名也会慢慢被搜索引擎所重视，这种现象曾经在SEO校长的文章(百度的软肋与百度所漠视的模拟搜索)中提到过。C、合理的关键词密度，切忌在标题中不要再堆积关键词了，这种手段已经太小儿科了。

The results suggested that compared with A-starch and maize starch, there are more quantities of impurities, such as protein, lipid and pentosan, in B-starch. B-starch prepared in the laboratory almost has the same compositions as three samplings, and accords with the reports of some documents too. Differing from the granules in A-starch, those in B-starch are smaller sized (1-10m)and oval shaped, and felted each other. The crystallogram of A- and B-starch are similar, i.e. A type. There is difference in granular distribution between A- and B-starch. The granular distribution of B-starch is anomalous and extensive (l~1259m).B-starch has bigger dilatancy and retrogradation, and smaller blue value, solubility, viscosity, gelatinization temperature and gelatinization enthalpy.

试验结果表明：跟玉米淀粉、A淀粉相比较，B淀粉含有的蛋白质、脂肪和戊聚糖等杂质数量多；实验室制备的小麦B淀粉中淀粉、粗蛋白、戊聚糖等含量均与文献的报道接近，也与在工厂采样的B淀粉相近；与A淀粉不同，B淀粉以小颗粒的淀粉为主，平均粒径1～10μm，颗粒形状呈椭圆形，同时颗粒和颗粒之间黏结紧密；B淀粉和A淀粉晶形结构相似，都为A型；B淀粉的粒度分布情况不同于A淀粉，其粒度分布规律性不强，分布范围也较宽，粒度在1～1259μm之间；B淀粉的凝沉值和膨润力大于A淀粉，而沉降体积、蓝值、溶解度、粘度、糊透光度、相变温度和热焓均小于A淀粉；杂质的含量对B淀粉性质的影响是明显的，随着杂质含量的增加，沉降体积、溶解度和透光度减小，膨润力增大，但是它们对凝沉值、蓝值和粘度的影响比较复杂。
