In stead of the ring Z〓 we construct the threshold schemes over a large prime field Z〓. When we need decrypt or sign, we transform the module from r to φ using a sample massage. The efficiency and implementability of the methods presented in this paper excel the exiting methods.

用一般大素域Z〓代替环Z〓建立门限秘密共享体制，在需要解密或签名时，利用样本消息实现从模r到模φ的转换，该方法的有效性和可实现性均优于现有方法。

The local peasant undergoes the process of class differentiation within rural village. From the 1980s onwards, they are under the pressure of proletarianization. They lost farm land and advantages in local market. These transformations change the social division of labor in rural village. The only way against this process is the expansion of village government and its administrative power. The need of strengthening security force leads to more recruitment of young people. It mitigates the pressure of proletarianization and forms the basis of the local society.

至於本地农民，他们经历了农村内部的阶级分化。80年代后，农民面对无产阶级化压力增加，农民失去土地，在地方市场上也开始失去优势，这些正在改变著农村的社会分工，唯一减慢或转化这个过程的是，农村基层组织的膨胀及吸纳，由於其基层管理权力的膨胀，以及加强治安能力的需要，增聘了不少年青劳动力，稍为纾缓了部份无产阶级化的压力，同时形成了本地社群的基础。

In view of disadvantages in present defect reconstruction methods,such as over-long time or excessive need for training samples,a new defect reconstruction method based on similar model and genetic algorithm was investigated as follows:similar model between non-axisymetric defect and axisymetric defect was represented,and proportionality factor was deduced by skin depth equation.

针对以往缺陷重构方法中普遍存在的计算时间长或需要大量训练样本的缺点，提出一种基于相似模型和遗传算法的缺陷快速重构方法，分析非轴对称缺陷与轴对称缺陷之间存在的相似模型，并利用集肤深度公式推导出两者之间的缩比因子，从而将耗时巨大的缺陷重构问题转换为二维轴对称情况下的计算问题；同时为进一步缩短重构时间，提出一种加快遗传算法收敛速度的方法。

In spite of the recent remarkable advance in biological psychiatry, including psychopharmacology, improving tremendously the psychiatric care of patients, particularly for those suffering from major psychiatric disorders, there is still a great need to promote psychotherapy for caring of patients suffering from minor psychiatric disorders or emotional problems.

虽然近年来生物精神医学，包括精神药物学，有显著的发展，对精神医疗有明显的改进，特别是对严重性的精神疾病，可是仍然很有需要推展心理治疗，特别是对轻度性的精神疾病或患一般心理问题的病人。

this paper introduces a lossless detected circuit system.firstly,system gathers slender infrared signal with transducer,then amplifies them with low noise.through voltage comparator circuit,transforming simulation objection signals to digital signals.finally,transforming transport landscape orientation and portrait to single chip processing.in design of pcb,the amplifying of quadruplet signal,filter,voltage comparator decree and and logic function are manufactured in one board.if the diameter of workpiece is long,it can add multiple the number of transducer of four,to wide its range of practice,disposing circuit only need one module.

摘 要：介绍了一种无损检测的电路系统。系统首先利用传感器采集到微弱的缺陷信号，再将缺陷信号进行低噪声放大，然后通过电压比较判决电路将模拟缺陷信号变换成数字信号，最终将横、纵两路的输出信号送至单片机处理。在pcb设计中，将四路信号的放大、滤波、电压判决以及与逻辑功能做在一块板上，若被检测工件的直径较大，可以将传感器的个数以四的倍数增加，处理电路只需增加一个模块。

Based on the technique of radiate temperature measurement, the author designs a circuit of prismatic decomposition colorimetric radiate temperature measuring. A high resolution A/D converter and measurement range switch technology are adopted to resolve the problem that it has lower radiation power and lower signal sensitivity in the low-temperature stage, while higher signal amplitude and higher need of dynamic range in the high-temperature stage. The technique of the Black Body Furnace demarcates, digital calibration and the quartic curve fitting are applied to correct the sensor and improve its measurement precision.

3研究了辐射温度测量技术，设计了棱镜分光比色辐射温度测量电路，使用高分辨率A／D转换器和量程切换技术解决低温段辐射能量小、信号灵敏度低，而高温段信号幅值大，动态范围要求高的矛盾，应用黑体炉标定技术和数字校准方法以及4次拟合校正技术提高温度测量精度。
