Search for new antiphytovirucides

The lead compound of substituted 2-(4′-hydroxyphenyl)benzimidazoles were modified by phosphorylation sulfonation and carboxymethylation. The benzimidazoloamidophosphate (6) (7) have better activity against tobacco mosaic virus (TMV). The benzimidazolophenoxyacetic acid, phenoxysulfonic acid containing trifluoromethyl, and nitro group have 77%≈85% efficiency for wheat rust disease.

Cloning and expression of the vp39 gene ofBombyx mori nuclear polyhedrosis virus inE. coli

The nuclear capsid protein gene (vp39) ofBombyx mori nuclear polyhedrosis virus (BmNPV) was amplified successfully by PCR technique and inserted into pGEM 3zf(+). The 5′ and 3′ terminal area of the amplified vp39 gene were sequenced with silver-staining dideoxy method. Bmvp39 gene was sub-cloned into the expression vector pRSET-A, and transformed intoE. coli BL21. This gene was highly expressed by IPTG induction. SDS-PAGE analysis showed that the expressed protein is about 38 kd, and the expressed amount reached maxium in 4 h with IPTG induction.

企业员工绩效考评方法研究及应用

本文提出了一种新的员工绩效考评方法－ＡＦＴ,即用层次分析法（ＡＨＰ）确定考评指标的权重,用模糊数学的方法（Ｆｕｚｚｙ）对各类质化考评指标值进行量化处理,并进行系统的综合,用逼近于理想解的方法（ＴＯＰＳＩＳ）排出被质评者的优劣顺序。     

再生丝心蛋白和羧甲基纤维素复合膜的特性及其在有机相葡萄糖生物传感器中的应用

用再生丝心蛋白和羧甲基纤维素构成的复合膜作为固定葡萄糖氧化酶的基质,并用红外光谱测试了该复合膜的结构,用扫描电子显微镜观察了其形态．用上述复合膜材料固定葡萄糖氧化酶和羧酸二茂铁（或７,７,８,８－四氰代二甲基苯醌,ＴＣＮＱ）制成的葡萄糖生物传感器具有较好的灵敏度与稳定性     

整（0,m）插值的推广

引进了一类新的指数型整函数插值,推广了（０,ｍ）插值,同时也考虑了该插值算子的收敛性。     

利用RAPD标记鉴定芥菜(Brasica juncea Cos.)品种(英文)

从６０种１０ｂｐ随机引物中筛选出７种引物,对８个芥菜变种的１６个品种（每个变种有２个品种）进行了随机扩增多态性ＤＮＡ（ＲＡＰＤ）鉴定,能快速、灵敏、较为简便获得了１６个芥菜品种的基因组ＤＮＡ指纹图谱．结果表明,不同引物在１６个品种上都有其特征ＤＮＡ带,一般只有１条,少数有２条．在同１个变种的２个品种之间存在着丰富的ＲＡＰＤ标记,通过比较２个品种各自独具的ＲＡＰＤ标记,就可明确地将２个品种区分．在所用的７种引物中,没有１种能同时将８对芥菜品种全部区分开,但用２种或２种以上的引物就完全可以将８对芥菜品种全部区分开．     

SrxBa1—xTiO3陶瓷的频域介电谱

用固相反应法制备ＳｒｘＢａ１－ｘＴｉＯ３系列陶瓷．当ｘ＝０．３０时呈现显著的驰豫相变特征．在５Ｈｚ至１ＭＨｚ范围,相对介电常数的实部ε′随频率ｆ的降低而增大．１／ε′与ｌｇｆ的关系曲线呈现折曲的２段直线．高频相对介电常数的实部ε′ｈ随ｘ的增加而增大是与顺电相的增加而对应．测量点（ε′,ε″）随频率ｆ的变化分布在复平面的一条直线上．
