After removing the catalyzer by dense muriatic acid, carbon nanotubes are reacted with mix acid (vitriol:nitric acid=3:1 vol./vol.). By comparing the surface image of gained carbon nanotubes under the different condition, the best mix acid oxidation temperature is fixed on 140°C and the reaction time is 30min. The soluble carbon nanotubes were prepared by decorating of octadecylamine on the surface of nanotubes. Three processes of grafting were investigated in this research.

The effects of NaAA content on the mechanical properties and water-swellable properties were studied. The experimental results show that NaAA has good reinforcement for the EVM vulcanizate. EVM vulcanziate reinforced by NaAA has higher water absorbing rate and equilibrium water absorbing ratio. When the NaAA content is 50 phr, the maximum water-absorbing ratio of EVM vulcanziate is 278.3%. With the incorporation of ion into immersing media, the water-absorption ratio of EVM vulcanizates decreases. FT-IR analysis confirms that NaAA formed in the process of compounding and underwent polymerization during vulcanization.

The paper are studied dynamics characteristic of IR smoke under entironment to vacuum and micro-gravitation,based maths-model of thermodynamic onflow pervasion by smoke formed, the experiment proves that the movement speed of smoke gradually minishes along with hoist of vacuum.The process after smoke formed analysed ,which proves that its movement rule relates hilum of particle.

本文对真空和微重力环境下的红外烟幕进行了动力学特性研究，建立了烟幕形成过程中的热力湍流扩散数学模型，通过实验表明随著真空度的升高，烟幕的运动速度逐渐减小；并对烟幕形成后的过程进行了分析，结果表明其运动规律跟粒子的粒径有关。

The result shows that Co and Cu are associated with exchangeable fractions, which represents stonger mobility;Pb in iron-manganese fraction represents stonger potential mobility;Zn and Cr existed in oxidizable and residual fraction and Ni in residues represents weak mobility or immobility.

研究结果表明：Co、Cu、Mn存在可交换态，表现有相对较强的迁移性和生物可利用性；Pb主要以还原态的形式存在，表明具有较强的潜在危害性；Zn、Cr主要以氧化态和残渣态形式存在，Ni主要以残渣态的形式存在，这些元素的迁移性较弱。

Comparison between the velocity distributions at the different flow rate conditions showed that increasing the flow rate was help to improving the velocity distribution. The periodic mean field on r-6 plane at different axis positions showed that the flow within the vaned diffuser, especially within the inlet region, was periodic unsteady when impeller located at the different circumferential position, just as the flow within the vaneless diffuser.

有叶扩压器内平均流场的分析表明，在定常流动的假设下，不同流量工况下有叶扩压器的内部流动也呈现为沿轴线向后盘方向推移流动状况逐渐恶劣的分布规律，表明二元叶片构成的平行直壁有叶扩压器对轴向不均匀流动的掺混作用仍然不大。

The feature of oxygen isotope for magnetite from Abagong iron deposit reflects that the water in the fluid of mineralization resides in the initial magma, implying the magma genesis of mineralization. The similaritary features of REE and trace elements for coexisting apatite with magnetite in the Abagong, the Kiruna type and the Ninwu porphyrite iron deposit show their common genesis, indicating that Abagong iron deposit resulted from the intrusion of late ore magma due to the magma differentiation. The characteristic of sulfur isotope composition implies that the Abagong iron deposit resides in basaltic magma from mantle resource.

阿巴宫铁矿磁铁矿氧同位素特征反映了成矿流体中水来源于原始岩浆水，暗示该铁矿的岩浆成因；与磁铁矿共生的磷灰石稀土和微量元素特征与Kiruna型铁矿以及宁芜玢岩铁矿中磷灰石特征非常相似，表明它们具有相同的成因机理，反映出阿巴宫铁矿为岩浆分异的晚期矿浆贯入式成因；其硫同位素特征表明成矿物质源自幔源的玄武质岩浆。

The main conclusions indicated that NDVI values seemed to be turning up in the area during recent 22 years (1982—2003). That suggested the vegetation cover was improved in Guizhou. The NDVI increased in the spring and autumn and decreased in the summer and winter. The spring made the largest vegetation contribution in all seasons. Vegetation cover was different from the area and the variation was positive in the central area but negative around the edges of Guizhou.

结果表明：22年来，研究区植被覆盖呈增加趋势，表明贵州省植被生态环境向好的方向发展；贵州省平均植被覆盖在春季和秋季呈上升趋势，夏季和冬季呈下降趋势，其中春季对植被覆盖总变化量的贡献最大；植被覆盖程度增减因区域不同而异，变化程度呈增加的区域主要位于贵州省的中部地区；变化程度呈减小的区域分布在贵州省的四周边缘。

Changes of silver carp muscle protein s during chilled storage;2. The changes of rheology,texture and color of minced pork after the cooking respectively in water bath,retort and microwave were tested,based on which the effects of muscle protein and transglutaminase contents on the gel properties of minced pork were then investigated.

结果表明：3种热处理方法下，一定量的转谷氨酰胺酶及肌肉蛋白使猪肉糜表现出不同的颜色和质构特性；与其他两种方法相比，水浴加热使猪肉糜更具有弹性；加入MTGase后，样品的储能模量G′增大，表明MTGase的加入影响了猪肉糜的流变特性、颜色以及质构，其效力取决于猪肉糜的热处理方法。
