Fuzzy neural network is used in the three phase adaptive reclosure so that the reclose of permanent faults can be avoided. A multi-input fuzzy neural network is constructed and the algorithm of network is designed. Taking the virtual value of three phase voltage as the input with its scale changed, the network learning can be completed with convergence reached after the process of fuzzification, normalization and perspicuity, so it can disinguish transient faults from permanent faults.

为了避免重合闸重合于永久性故障，将模糊神经网络应用于三相自适应重合闸中，构造了一个多输入的模糊神经网络，设计了网络的算法，将三相端压有效值作为输入，经尺度变换、模糊化、归一化和清晰化，并利用梯度下降法修正误差，使得网络完成学习并最终收敛，在输入故障数据时能根据网络的输出结果准确地判别瞬时性故障与永久性故障。

In this paper, The influence of heat set and dyeing on the structure of PTT fiber was investigated by FT-IR, DSC, critical dissolution time. The influence of heat set on the dyeability of PTT fiber was discussed, too. Meanwhile, many experiments on the dyeing performance of PET fiber were carried out. The effect of different dyeing temperature on the uptake and visual color depth value and dyeing characteristics of different dyes with temperature increasing were discussed, and the influence of temperature on the dyeing depth were also evaluated when dyeing for PTT and PET fiber in the same dye bath condition. Especially the kinetics and thermodynamics of dyeing with disperse dyes were mainly studied.

目前，我国对PTT染色性能方面研究报道还少，本文用傅立叶红外光谱、差热分析、临界溶解时间等分析方法研究了热定型和染色对PTT纤维结构的影响，探讨了热定型对PTT纤维可染性的影响，同时进行了多项PTT纤维的基本染色性能试验，探讨了不同染色温度对上染百分率及表观色深值的影响、不同染料的升温上染特性、不同染料的移染性能和染深性能以及PTT和PET纤维同浴染色时染色温度对它们的染色深度的影响。

After bleeding sloped, the hemoglobin amount in films or gauzes were measured to determine the hemostatic effect Using a randomized design, one incision in each animal was treated with C-CM membrane, the influence of C-CM film on the growth of bacteria (Staphylococcus aureus ATCC 27853. Escherichia coli ATCC 25922. Monil lia albicans ATCC 14053)were observed in vitro with solid medium. Rusults: It was observed that C-CM membrane had no toxic effects on surrounding tissue and was slowly degraded after implanted into rat leg muscular porch ; The results of hemostatic experiment showed that C-CM film adhered well to incisions.

结果：C-CM膜植入动物肌肉中，周围组织无明显炎症，未发现组织变性和坏死，可在组织内缓慢降解，具有良好的组织相容性，6周后反应接近外科缝合丝线组；止血实验结果发现：C-CM膜组和纱布组的出血时间分别为83.5±9.333s和117±15.9275s，血红蛋白光度吸收值为0.9204±0.7559和1.9764±0.7205，二组比较差异显著(P＜0.05)，说明C-CM膜有一定的止血作用；促进创面愈合实验结果显示：不同时间段C-CM膜组肉芽组织较对照组厚，其中胶原纤维含量亦较多，C-CM膜组的创面愈合时间早于空白对照组，伤口愈合较快；抑菌实验显示C-CM膜对三种菌产生接触性抑制。

In experiment 2, the semen quality of 2 boars from Ilan Yiyang farm were diluted with BTS and MIII extender and stored for 3 days in the initial stage. The parameters of semen quality were including pH, motility, maturation, acrosome integrity and normal morphology of spermatozoa in diluted semen stored for 1 and 3 days. The diluted semens were also used for in vitro fertilization to evaluate the sperm penetration, polyspermy rate and the average number of spermatozoa per oocyte as IVF parameters.

试验二使用宜兰宜阳养猪场之2头性成熟公猪，采取精液后分别以BTS与MIII稀释液进行稀释，在保存1日与3日时检定其pH值、精子活力、成熟率，形态正常率等性状，并用此稀释保存之精液进行体外受精，纪录精子穿透率、多精入卵率与平均入卵精子数。

The analyzing aboved is made from earthquake's space distributing, periodicity, migration phenomenon, repetition, strength, frequency, b value etc., according to data of earthquake station net in Shaanxi Province and microseisms station net watching results in Xi'an area. 3 group faults which are NEE, NW and EW direction control earthquake activities in Guanzhong area. Epicenter depth mostly is 5-25km and in shallow-focus earthquake. Earthquake in east area of Guanzhong was stronger and weaker in the West in history. Fen-Wei earthquake belt showed more activity. Microseisms and small seisms is main movement in recent earthquake, it has 8-10years' period of movement and show the trend that they are strong in the West but weaker in the East. And frequency and biggest magnitude of earthquake is supplement each other. In next years earthquake frequency will lessen but strength enhance, about M4. It presumes there is earthquake climax period in Guanzhong area in 2040 and M5-6 earthquake is happened at that time.

本文在对关中地区区域构造及重磁异常特征的分析基础上，根据陕西省地震台网监测资料及西安地区微地震台网监测成果，从地震的空间分布特征、周期性、迁移现象、重复性、强度、频度、b值分析等方面，对区域地震活动特征、关中地区地震活动规律进行了分析研究，关中地区地震活动主要受北东—北东东向、北西向、东西向三组方向的断裂控制，震源深度多为5—25公里，均属浅源地震，历史地震表现为东强西弱，东部的汾渭地震带表现出较强的地震活动性，近代地震活动主要以微震或小震为主，存在着8—10年的活动周期，近期表现出西强东弱的趋势，地震的频度与地震最大震级呈互补关系，未来的几年间，地震频度会有所减少，强度会增大，将有可能发生4级左右的地震，推测在2040年左右，关中地区将进入地震高潮期，届时将可能有5—6级左右的地震发生。
