The transfer behavior of pyrazolone derivatives, such as antipyrine, aminopyrine, 4-aminoantipyrine and analgin, across the W/NB interface was investigated. The three medicines studied can form complex with a proton and the complex formed can transfer reversely across the W/NB interface and the transfer process was controlled by diffusion. The transfer of protonated analgin was not observed within potential window because of its high transfer potential.

研究了吡唑啉酮类的安替比林、氨基比林、4-氨基安替比林和安乃近四种药物在W/NB界面的转移行为，前三种药物在一定pH值的水溶液中结合一个质子形成1∶1质子配合物，并能在W/NB界面发生可逆转移，其转移过程受扩散控制，安乃近的质子化物由于有较高的转移电位而未在电位窗内观察到其转移峰。

Two specieses, Lycoris radiate and Lycoris aurea, were selected for the studying of artificial propagation in vitro. A few specieses of Lycoris, from the southeast area of China and part of locations in Japan, were chosen to research their karyotype differentiation and to measure their genetic diversity by ISSR analysis. The results could be summarized as follows.1. The vegetative propagation conditions of Lycoris aurea and L. radiate in vitro was studied by two-scaling. Different illuminate condition had an effect on the bulblet formation rate. To the species of L. radiate, the rate was higher in the state of 16h 800-12001x illumination than in the darkness. The medium also affected the new bulblet formating rate. When the culture was MS medium 0.2 mg/L NAA 4 mg/L 6-BA, the bulblet formationg rate of L. aurea was 220%;at the same time, when the medium was MS 0.2 mg/L NAA 2 mg/L 6-BA, the rate of L.

本研究选择西南部分地区及日本的几个石蒜品种，从细胞学和DNA分子角度，分析了它们的遗传多样性水平和遗传结构状况，对红花石蒜和忽地笑的离体繁殖技术进行了初步研究，得出如下结论： 1 进行了红花石蒜和黄花石蒜双鳞片快速繁殖条件的研究，结果表明：红花石蒜在16小时800-1200 lx光照下比黑暗条件下出芽率要高；黄花石蒜在MS NAA0.2mg／L 6-BA4mg／L下出芽率为220％，红花石蒜在MS NAA0.2mg／L 6-BA2mg／L下出芽率为108％；NAA比IBA有利于石蒜生根；硅藻土显著提高黄花石蒜双鳞片出芽率，活性炭起抑制作用；6％蔗糖浓度有利于红花石蒜小鳞茎增重，MS 6-BA4mg／L NAA0.5mg／L培养基有利于小鳞茎增殖，切割一刀比两刀有利于小鳞茎增殖。

The analysis shows that the reflection spectrum is the multiple beams interference, and the coupling ratio is similar to the reflection coefficient of Fabry-Perot cavity. The larger the ratio is, the finer the extinction ratio is and the narrower the full-width at half maximum will be.

分析表明器件具有法布里－珀罗腔干涉仪的特点，耦合器的耦合比系数类似于法布里－珀罗腔的反射率，耦合比系数越大，输出光谱半高全宽度越窄，消光比越好。

Because Pinot Noir prefers cool weather, the vineyards in California concentrate on the sea fog belt, such as Russian River Valley, Oregon and Sants Barbara, and Pinot Noir of premium class can be produced in Vineyards with high altitude such as Santa Chalone, Calera.

由于黑比诺喜欢凉爽的气候，所以加州的黑比诺葡萄园都集中在受到海雾影响的地带，比如Russian River Valley、Oregon和中央海岸包围的Sants Barbara，而海拔高的葡萄园（如Santa Chalone、Calera等地方）则能出产很棒的黑比诺。

The comparative tests of the rheological properties between Alcalase induced soy coagulum and Magnesium Chloride/Calcium Chloride induced soy coagulum shows that the former one has higher hardness,lower strength,and 10 times higher adhesiveness of the latter one.

对Alcalase与盐类凝固剂氯化镁和氯化钙凝固豆乳的主要流变学性质比较发现，Alcalase凝固豆乳的硬度比盐类凝固剂大，凝胶强度比盐类凝固剂低，粘附性比盐类凝固剂高10倍以上，使凝胶较粘，乳清不易排出。

According to comprehensive efficiency Low-E glass gets 0.08% of daylight factor more than clean glass, however, clear glass compare to Low-E glass obtains an excessive amount of illuminance, lead to indoor temperature is too high.

综合效能评估结果中，Low-E玻璃的综合效益比清玻璃优异，但两者相差约0.08 %/℃，因为清玻璃却比Low-E玻璃取得过量的室内照度，导致室内的温度比Low-E玻璃高。

Whether the inner cylinder is drilled or not do not affect obviously the measurement accuracy. The accuracy of the drilled outside cylinder is higher than the undrilled ones, and the drilled holes are better to be equally distributed, further more, the number is less than 36 with the diameter of 3mm. The sealed outside cylinder can lower the measurement accuracy. The thinner material of sealed inside cylinder is and the more ventilative function is, the higher accuracy will be achieved. Moreover, when the space between inside and outside cylinder is smaller, the measurement accuracy also becomes higher.

结果表明：各处理精度均较高，最高达97.40%；内筒打孔与否对测量精度无显著影响；套筒打孔的处理比不打孔的处理精度更高，且孔洞适宜均匀分布，但数目不可过多，直径为3mm时不宜超过36个；套筒封底会降低测量精度，内筒封底材料越薄、透气性能越好精度越高；内筒与套筒的间隔较小时精度更高。
