Plantlet regeneration from cotyledon of Citrullus lanatus cv. Zhangkang No. 4 was studied. The results showed that aseptic seedlings should be cultured in dark for 3d, then exposed to a photoperiod of 16/8h/d for 3d. The callus induction rate was higher in cotyledons placed facing downwards to the medium than in those facing upwards. The highest induction rate occurred in MS medium containing 6-BA (2.0mg/L), kinetin (1.0mg/L)and GA3 (1.0mg/L). The induction initiated in dark and took 7 days, while callus growth and differentiation proceeding for 7 days under 16/8h light-dark cycles. A highest rate of embryogenic callus was obtained after 3 successive subcultures.

药敏结果显示各种病原菌对青霉素类及头孢类抗生素有较高的耐药率，而对亚胺培南-西司他丁有较高的敏感率，达80%以上，革兰阳性球菌对万古霉素敏感率达85%以上。

And abortion rate,efflux time of gestation sac,time of colporrhagia and returning menstruation, adverse reactions were examined.results the abortion rate,efflux time of gestation sac,time of colporrhagia and returning menstruation in three groups didn't have significant difference.but adverse reactions in them were shown significant difference.the complete abortion rate of pregnancy women less than 6 weeks was higher than that of 6～8 weeks.conclusion shorter course of treatment,minor response were shown.group a possesses advantages of short time,exact effect and little side effect,especially in less than 6 weeks duration of pregnancy.

结果：三组完全流产率、孕囊排出时间、出血时间及月经复潮时间差异无显著性；a组妊娠小于6周者完全流产率与妊娠6周～8周者相比差异有显著性；疗程短者出现副反应小，三组差异均有显著性。结论：米非司酮服用时间越短，其胃肠反应与头晕乏力等副作用越小；a组具有用时短、疗效确切、副作用小等优点，尤其对孕周小于6周患者流产效果好。

Analytical results show that: Anode evaporation rate, which determines mostly the production rate of UFMP, is influenced by the many factors including electric parameters of arc, ambient conditions and material properties et al; Existence and increase of anode ejection can influence the production rate and property of UFMP; It is firstly found and investigated that surface connexity phenomenon of Al anode material. Analyses and calculation show that formation of anode spot and existence of self-magnetic field force play an important part in surface connexity process; Effects of cathode material on prepared UFMP is also experimentally studied and theoretically analysed. It shows that effect of the cathode is inconsiderable under the experimental conditions used in the study. At last, the experimental results found in part one are analysed and discussed in detail.

然后详细分析了电弧与电极间的相互作用过程，结果表明：决定超微粉产率的阳极材料蒸发率受许多因素影响，它主要与电弧电参量，环境条件及材料性质有关；阳极表面液滴喷溅的存在和加剧将严重地影响所制超微粉的产率和性质；首次发现和实验研究了Al阳极表面凸起现象，并对此现象进行了详细的理论分析和实际估算，认为阳极斑点的形成及自磁场作用力的存在在该过程中起着重用作用；实验研究和理论分析了阴极材料对所制超微粉的影响，认为在本文所用实验方法及条件下，阴极材料对粉的影响很小。

In the study of non-isothermal crystallization kinetics, we found that the Avrami constants were enhanced with the increase of the amount of the modified MMT at 10 ℃/min and 30 ℃/min. But it decreased with the increase of the amount of the modified MMT while the cooling rate increase to 50 ℃/min. The crystallization rate constat k also increased with the increase MMT and it revealed that the crystallization rate of composites accelerated by the presence of MMT.

由非等温结晶动力学得知，复材之Avrami 常数n值在10℃/min与30℃/min时，会随著改质蒙脱土含量增加而上升，但是当降温速率提升至50℃/min时，则随著改质蒙脱土增加而下降，其结晶速率常数k值随著改质蒙脱土含量增加而上升，代表复材之结晶速度也会受到添加改质蒙脱土的影响而变快。
