An antisense expression vector of the cattleya-ACO gene, which named pBI121ACC, was constructed, and the autisense sequence was controlled by the CaMV 35S promoter. The work laid the foundations of the future transgenic research for prolonging the flowering period of the transgenic Cattleya via autisense technology.

将克隆的卡特兰ACO片段反向连接到植物表达载体pBI121中CaMV35S启动子的下游，构建了卡特兰ACO基因的反义表达载体pBI121ACC，为进一步应用反义技术培养长花期卡特兰新品种奠定了基础，也为首次应用生物技术延长卡特兰花期做出了尝试。

Objective: To investigate the effect of shoe heel height on the ground reaction force and the center of sole force.

目的：通过研究女性行走时地面反力和鞋底压力中心，探讨鞋跟高度对地面反力和鞋底压力中心的影响。

When the subjects wore shoes with different heel height and walked in different speed the ground reaction force and the track of the center of sole force were measured and analyzed quantitatively.

Among the large number of nonlinear absorbers, the material applied most extensively is phthalocyanine reverse saturable absorption compound which is organic large molecule with central symmetry two-dimensional π-electron conjugate system. In the off-resonance condition, its absorption coefficient will raise along with the increasing of incoming light intensity, which shows its reverse saturable absorption properties.

在非线性光学材料中目前最具应用价值的是酞菁类的反饱和吸收材料，这是一类具有中心对称二维π电子共轭体系的有机大分子，在非共振激发条件下，吸收系数往往会随入射光强的增加而增加，体现反饱和吸收。

These were Pseudomonas stutzeri, Bacillus cereus and Acinetobacter junii, which were used to improve water quality.

Our results show that once the hopping effect is considered, the charge carrier in trans-polyacetylene is soliton-antisolition pair, not the single polaron.

我们的结果表明，一旦hopping效应被考虑，反式聚乙炔中的载流子将是孤子反孤子对，而非单个极化子。

The experimental results were followed:(1) LY402 could degrade chlordane in an aerobic environment. The percent of chlordane degradation at 1.0 mg /L was more than 94% after 4 days at 30℃. When exposed to a concentration as high as 10.0 mg/L, LY402 could still degrade 61% of chlordane. There was no obvious difference between cis-chlordane and trans-chlordane in the mixture on biotransformation rate.

实验结果表明：(1)在好氧条件下，LY402能够有效降解氯丹，对于1mg/L的顺式氯丹和反式氯丹混合物，在30℃下，经过4天的好氧降解，其总降解率接近95%，进一步将氯丹混合物的总量增加到10.0mg/L，其4天的总生物降解速率仍然能够达到64%，其中，顺式氯丹和反式氯丹的生物降解速率没有明显区别。

Methods A recombinant antisense GFAP retrovirus was developed. After packing and concentrating, the suspension of this retrovirus was injected into the sites of injured brain stab by a microinjector. The effect of recombinant antisense GFAP retrovirus on formation of glial cicatrix in the injured sites was studied through immunohischemistry and morphological observation.
