Four thin-layer drying models were investigated for the description of FIR-assisted freeze-drying characteristics. The models were exponential model, Page model, diffusion model, and approximation of the diffusion model. Tests were conducted using a three-level, three-factor (drying temperature, distance between sample and FIR heater, and sample thickness) design, and quadratic polynomial analyses were performed to relate the drying parameters of thin-layer drying model. The performance of these thin-layer drying models was evaluated by comparing the coefficient of correlation (R2), the sum of squares, and the RMSE amongst four models. Drying parameter K of the Page model gave the best results in describing freeze-drying with FIR of Tylose and sweet potato.

运用四种薄层乾燥模型（指数、Page、渗透模型及近似渗透模型）研究远红外线冷冻乾燥之乾燥特性，实验采用三阶层、三因子（远红外线加热器设定温度、远红外线加热器至样品表面之距离及样品之厚度）的实验设计，对於薄层乾燥模型的乾燥参数以二次多项式函数表示之，乾燥参数之二次多项式函数的最适性判断主要是藉由决定系数、模式缺乏适合性及均方根误差等值的比较而加以评估，以Tylose及甘薯样品而言，其中四种薄层乾燥模型的乾燥参数以Page模型之K值的结果为最佳。

However, the value of magnetoresistance increased apparently after annealing and was 1.74 times the unannealed sample. XRD structural analysis shows that peak intensity of the annealed sample is greater than that of the unannealed one which demonstrated an increase of crystallinity.

实验结果表明：退火后样品的薄膜电阻率显著减小，是未退火样品薄膜电阻率的3.17分之一；而退火后磁电阻值则明显增加，是未退火时的1.74倍；XRD结构分析显示，退火后薄膜样品的峰值强度大于未退火样品的强度，说明样品结晶度增强。

The specimen horizontally into two of the instrument, sample between the edge of the circular underpan between the minimum distance of not less than 50-mm, measurement should be gently 2 ~ 3 mm/min will activities on blank sample in order to avoid any impact, and make sure the piece and thickness measurement plane parallel.

将试样水平地放入仪器的两个平面之间，试样的边缘与圆形底盘边缘之间的最小距离不小于50mm，测量时应轻轻地以2～3mm/min的速度将活动平面压在试样上，以避免产生任何冲击作用，并保证试片与厚度仪测量平面的平行。

So during the collection of fault sample data and checking data, the paper sets up the mathematics model of control system first. We cause all kinds of fault in the control system, then collects a variety of fault data. After unitarily dealing, the fault data server as the sample data of training neural network. At the same time, according to the collection of checking data, it examines whether the trained neural network have the function of fault diagnosis.
