The results showed that the three disparate treated substances have no visible antibacterial effect to E. coli , but a obvious effect to Staphylococcus aureus with inhibition of about 10 bacteriostasis units; have dissimilar effects to 10 kinds of fungi among the total kinds, and have a good inhibitory effect to Cytospora.coccodesHughes with fungistasis rate above 65%. After the gel filtration and activity detection, 50mM ammonium acetate was screened out as the more suitable eluents, the crudes were separated into strikingly unlike parts with obviously different antimicrobial activity.

结果表明，大蜡螟抗菌物质对大肠杆菌没有明显的抑制作用，而对金黄葡萄球菌抑制作用明显，抑菌活性单位在10左右；对10种植物病原真菌均有不同的抑菌活性，其中对苹果树皮腐烂病菌的抑制率达到65%以上；经过凝胶过滤分离，及对分离组分的抑菌活性测定，筛选出较合适的洗脱液为50mM乙酸铵，各分离组分抑菌活性差异明显，粗提物被分成了两个差异显著的部分。

This research is taking sea perch as the material, and cloning the Syntaxin 1B gene. After extracting RNA from sea perch tissue, we gained the first chain of cDNA by RT-PCR. Then designing a pair of primers according to the sequence of Syntaxin 1B from other organism. Based on the first chain of cDNA cloned from sea perch, the partial sequence of Syntaxin 1B gene is been cloned by using TD-PCR and we received the 751bp fragment at last.

本实验从鲈鱼脑组织中提取总RNA，通过反转录得到cDNA第一条链，根据已克隆出的其它生物的Syntaxin 1B基因序列，设计并合成引物，在妒鱼syntaxin1B基因部分序列克隆与分析 cDNA第一条链的基础上使用降落PCR，进行体外扩增妒鱼 Syntaxin IB基因的部分序列，得到长度为75 lbP的片断，在胶中洗脱下该片段，与pMD 18一T载体链接，转化入感受态细胞，挑取阳性克隆扩大培养，提取质粒，经HindIH和x一gaH两内切酶消化得到75 1 bp的片断，证明链接成功。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
