A test model of four co-rotating disks was developed as the simplified version of a typical internal cooling system of a gas turbine compressor. The investigation was on the distribution of local heat transfer coefficient and the averaged nusselt number of the downstream main disk. Experimental analysis may lead to following conclusions: the distribution is not of monotony and multi-peaks were found along the disk surface,Nu increases with the decrease of the rotational reynold number Re(subscript w,Nu increases with the axial reynold number and the grasholf number.

针对航空发动机多级压气机盘腔的冷却问题，对具有轴向通流的三腔模型进行了系统的研究，通过对局部换热特性与平均换热特性的分析，可以表征旋转盘的热应力水平和相对冷却效果，结果表明表征旋转盘热应力水平的局部换热特性在旋转盘的半径上呈多峰分布，表征相对冷却效果的平均换热特性与旋转雷诺数Re、进气雷诺数Re以及格拉晓夫数Gr有关，当Re及Gr增加时，平均努塞尔数Nu随之增加，而Re的增加使之减小。

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。
