After confluence, there is no clear margin between cells and only nuclear apophysis could be observed. Cell monolayer was smooth like quiet lake surface.

自制的胚胎冷冻液含有三种不同的冷冻保护剂(包括渗透性和非渗透性保护剂)，冷冻胚胎解冻后可用率在95％左右，比常用的DMSO冷冻液更适宜于这三种细胞的冷冻保存。

Anesthetic effects of MS-222, clove oil and benzocaine on American shad Alosa sapidissima fingerlings were studied and two-hour transportations of the shad were conducted at the optimal anesthetic concentration.

Study on the rapid Propagation Technique of Lycoris. Herb and get follow results: In the period found of axenic clone 0.1%HgCl2 is the best disinfector to deal with the Lycoris" bulb ,as to neat part, such as root, leave, and bulbil, is fit to use 0.1%HgCl2 antisepsis 7min. And found the best effect is the bulb scale with base. Root, leaf and bulb scale without base all were not inducement adventitious buds. Different position of bulb had different culture effect. 3-15 of middle part of bulb can be induced most adventitious buds but inner and outer of least it. Incised the bulb with three types (pieces of eight, pieces of six, piece of four), and found the type of pieces of six is best to Lycoris mass production. L.sprengeri is fit MS+BA5mg/l+NAA0.1mg/l and L.squamigera is fit MS+BA5mg/l+NAA0.5mg/l, but the medium fit to culture L.longituba haven"t be found.In the period of Subculture-Found of mass production, the most multiplication of adventitious buds in MS+BA5mg/l+NAA0.5mg/l during subculture of L.sprengeri, L.squamigera.

石蒜属植物快速繁殖技术研究中，在无菌无性系建立阶段：鳞茎以0.1％HgCl_2消毒10-12分钟效果最好，而叶、根尖、鳞芽等较干净部位选用0.1％HgCl_2消毒7分钟；用三种石蒜属植物的叶片、根尖、鳞芽及带基盘与不带基盘鳞片进行培养，以带基盘鳞片诱导分化效果最理想，鳞芽易培养出芽，但数量有限，而叶片、根尖与不带基盘鳞片均未诱导分化；带基盘鳞片为石蒜属植物快速繁殖最佳外植体，以鳞茎中部3-15层芽诱导率高，较外层稍次之，内部鳞片诱导率最低；选用八等分法、六等分法、四等分法切割鳞茎，六等分法综合效果最好；每外植体带三鳞片培养最为适宜；三种石蒜属植物各自适合的培养基成分不同，换锦花在MS+BA5mg／l+NAA0.1mg／l中培养效果最好，夏水仙为MS+BA5mg／l+NAA0.5mg／l，而白花长筒石蒜在各培养基组合中培养效果均不理想，其适合的培养条件有待于进一步研究。

The SARS virus origin which obviously differs from the theory of out space origin and the theory of wildlife origin was theoretically discussed based on principles of pollution evolution ecology,pathogenesis and infectant characteristics of SARS,and some relevant experimental evidence. It emphasizes on the fact that increasingly combined pollution in China provides a substantial basis for virus evolution.

针对当前广为流传的SARS病毒"太空起源说"和"野生动物来源说"两种理论，本文根据污染进化生态学原理和SARS病毒发病传染特征，以有关实验结果为科学依据，阐述了SARS病毒的起源问题，指出：我国当前环境日益严重的复合污染为SARS致病病毒的产生提供了适宜的外部生态条件和物质基础，SARS致病病毒可能起源于多个病毒的基因重组或融合，更可能是一种来自于感冒病毒进化而形成的超级感冒病毒。

But there is, I think, a climate that is best for love--a way of living that hastens the maturity of this matchless gift.

但是我想有一种氛围对于培养爱是再适宜不过的了，即一种可以促进这种无与伦比的天赋发展成熟的生活方式。

The 9 common used insecticides of cypermethrin 4.5%EC, omethoate 40%EC, chlorpyrifos 40%EC, acetamiprid 3%EC, imidacloprid 10%EC provided excellent control for wheat aphids in fields. The control effects were over 90% at 7 days after spraying. The 9 insecticides had bad effects on aphidius and coccinellidae in three days after spraying and the number of two natural enemies decreased rapidly. But on the 7th day, the number of the two natural enemies increased and there were difference between those treated with imidacloprid, acetamiprid and abamectin and CK. BT had no evident difference compared to the control.

为了明确杀蚜药剂对麦蚜的防治效果、适宜的防治时期、对生态环境安全性和粮食作物食品安全性的影响，对4.5%氯氰菊酯、40%氧化乐果、40%毒死蜱、3%啶虫脒、10%吡虫啉等9种防治麦蚜的药剂进行了筛选，发现各药剂对麦蚜的防效较好，喷药后7d防效均在90%以上。9种农药在喷施后的3d内，对麦蚜的主要天敌蚜茧蜂和瓢虫影响较大，两种天敌数量锐减，但到7d时各处理蚜茧蜂数量均有回升，其中不同剂型的吡虫啉、啶虫脒和鲁植顺克处理的蚜茧蜂数量同对照相差不大。

Although these two conceptions of society are different, it is notable that both conceptions share one common goal to establish a good society by positing proper relations among the persons.

虽然这两种社会概念是不同的，值得注意的是，这两种概念有共同目标，即通过在人们之间确定一种适宜的关系来建构一个好的社会。

The results show that the suitable material for treatment is the bulb basal plate tissue with a thin part of scales after having been inoculated for 7 days,and regeneration dose is 50～60Gy,the optimum treatment dose for breading is 15～20Gy.In the small bulbs treated with 15Gy and 20 Gy,two mutants were selected,one is shorter with more leaves,the other expands faster.

结果表明，接种7D的外植体更适合作为水仙离体诱变的材料，其不分化剂量为50~60GY，半剂量为15~20GY，在10和15GY处理中，发现了两种小鳞茎突变类型，一种为叶片数增多的矮化突变体，一种为试管小球茎膨大速度加快，所以适宜辐射诱变的剂量为10~20GY。

In the small bulls tinted with l5Gy and 20Gy, two mutants were selected, one is shorter with more leaves, the other expands faster.
