The interfacial viscosity of HPAM-CTAB system at hexadecane-water interface was much higher than that of HPAM solution alone at hexadecane-water interface, indicating that there exists significant interaction between CTAB and HPAM; perhaps they could form complex which was adsorbed at the hexadecane/water interface, so the interfacial viscosity was increased.

HPAM和CTAB复配体系与正十六烷所成界面的界面粘度要比单一HPAM溶液与正十六烷所成界面的界面粘度要大一个数量级，这表明复配体系中CTAB和HPAM之间存在着明显的相互作用，这可能是因为两者之间形成复合物在油/水界面富集而使界面粘度升高。

The nautre of ester bond and sedimentary medium condition control the distribution pattern of organic acid ester in strong reductional environment and water-washed oxidized crude oils. The former features higher contents both of 9, 11-Octadecadienoic acid, methyl ester and Hexadecanoic acid, showing the non-reversible hydrolysis reaction of ester bond in condition of basicity; the later features higher contents of Hexadecanoic acid and Octadeanoic acid, and lower contents of nonsaturated and side-chain acid ester, indicating the reversible hydrolysis reaction of ester bond in acid condition.

酯键的化学性质和沉积环境中介质条件，决定了强还原咸水盐湖相和淡水湖沼相经水洗氧化次生变化的原油有机酸酯的分布特征，前者9，11-十八二烯酸甲酯与正十六烷酸为主，反映酯键在碱性条件的不可逆水解过程，后者以正十六烷酸和正十八烷酸为主，烯酸和支链酸很少，反映酯键的酸性条件的可逆性水解，烯酸经氧化向正十八烷酸，正十六烷酸转化。

Gene sequence was highly homologic with a gene encoding aβ- subunit of ATP synthetase and an EST originating from a cDNA in relation to water deficit stress, which both were closely associated with the protein functioning in stress resistance and ion transportation. The results suggested that No. 1 gene sequence was involved in stress resistance of apple rootstock. No. 2 gene sequence had high homology with a gene encoding a serine/ threonine kinase protein, indicating perhaps it was a new gene encoding the serine/ threonine kinase protein in apple rootstock. The gene sequences of A1 and A2 were highly homologic with a gene encoding aβsubunit of ATP synthetase.

对得到的差异片断进行回收、测序，通过BLAST和其它植物比对，发现Ⅰ号序列与一条编码ATP合酶β亚基基因和一条水分亏缺胁迫cDNA克隆基因EST的同源性非常高，该序列编码涉及到了抗性表达、离子转运基因，可能参与了植物抗性表达，说明获得的基因序列应是与苹果砧木抗性相关的基因；Ⅱ序列与一条serine/threonine kinase蛋白激酶的蛋白序列同源性比较高，核酸比对较低，可能是具有丝氨酸/苏氨酸蛋白激酶功能的新基因。A1、A2序列与一条编码ATP合酶β亚基基因的同源性较高。

Combined with the regional data the research indicates that (1) the Tianmenshan main body formed in the Middle Jurassic Epoch, whereas the minor body was the further differentiated and evolutive product of the main body;(2) in the Chongyi-Dayu-Shangyou ore concentrated area, the west of Gannan area, the diagenetic age and metallogenic age are basically concordant, and the mineralization concentrated during 150~155 Ma;(3) from the middle-plutonic granite intrusion to the hypabyssal granite-porphyry vein, the magmatic activities experienced only 1~5Ma, indicating there was the concentrated period of mineralization.

结合区域资料，研究表明：①天门山岩体的主体形成于中侏罗世，补体是主体进一步分异演化的产物；②在赣南西部的崇余犹矿集区内成岩与成矿的年龄基本上是协调一致的，成矿集中期为150～155 Ma；③岩浆活动由中深成相花岗岩侵入体演化到浅成相花岗斑岩脉仅相差1～5Ma，表明存在成矿集中期。

Central fenestrations did not affect the clinical outcomes, indicating that corneal compression by the lens in the para-central region as opposed to central post lens tear film suction may be the primary mechanism behind the hyperopic OK clinical effect.

中央开窗术并不影响临床结果，表明镜片对角膜旁中央区域的压缩，而非中央区镜片泪膜的抽吸可能是远视OK临床疗效的主要机制。

Deviation from the realized niche center of leading dominant species to the theoretical niche center of the community niche hypervolume appears to be much smaller than that of other species, indicating their affinities to the present array of soil variables.

优势种群的实现生态位中心点与理论生态位中心点的偏离明显低于其它种群，表明它们较适应现有的土壤因子状况。

The analysis of the fungal community similarity between different ecosystem-types showed that farmland soil and shelter-belt soil had the highest similarity, indicating that the soil moniliaceous hyphomycetes in this two ecosystem-types had more common species.

对不同生态类型土壤中淡色丝孢菌的相似性分析发现，农田和防护林带生境的相似性系数最大，说明这两种生境具有较多的共同物种；湿地和城市花园生境的相似性系数最小。

The high sensitivity and specificity of real time RT-PCR were shown by The test result, 10~7 of the diluted allantoic fluid infected by AIV can also be detected, and has no cross-reaction with common Avian virus and Avian vaccines, such as low virulent NDV and IB V vaccine.5 days after the broiler has been injected with AIV vaccine, no matter hypodermal or muscular injection, the real time RT-PCR has not found any AIV nucleotide, indicating the use of AIV vaccine has no effect on the test results.

在检测禽流感感染的尿囊液时，尿囊液稀释至10~(-7)仍可检出病毒核酸，荧光RT-PCR方法的特异性也很强，检测时与禽群常用的疫苗如新城疫弱毒疫苗、传染性支气管炎弱毒疫苗等均不出现交叉反应。

The argument is fatally weakened by merely calling for the collection of such fees without indicating how those fees will be spent to safeguard the future of the national parks and wilderness areas of Illium.

如此看来，这项论述受到了致命的削弱，因为它仅仅号召去征收这些费用，却并不表明，这些费用将如何被用来保护Illium国的国家公园和荒郊野地的未来。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.
