So piperylene petroleum resin was applied preferably in downstream products,and the products yield was increased by improving post treatment process.

介绍了国内外间戊二烯石油树脂合成技术的改进进展，主要体现在催化体系的改进及聚合单体和溶剂的改变，通过引入官能团及共混等方法改善间戊二烯石油树脂的色度、耐候性和相容性等性能，从而使间戊二烯石油树脂在下游产品中得到更好地应用；通过后处理精制工艺的改进，可提高产品的收率。

The stimulations of dexamethasone, lipopolysaccharide, erythromycin and hypertonic saline can significantly change the AQP1 expression in pleura, which indicate that AQP1 may contribute to the accumulation and clearance of pleuritic fluids.

地塞米松、内毒素、红霉素和高渗盐水刺激下胸膜组织AQP1表达的改变，提示存在炎症因子和渗透梯度下调控AQP1的途径，胸膜组织上AQP1可能参与了炎症性胸腔积液的分泌和吸收。

Research on the influence of polysilicic nanometer material on core wettability and augmented injection found that the core treated by polysilicic nanometer material with proper size may chan...

聚硅纳米材料对岩心的润湿性影响和增注实验研究发现，采用合适的聚硅纳米材料处理岩心，能够改变岩石润湿性，可以较大幅度地提高岩心的渗透率，改善注水效果。

A number of Polytechnics have also merged together and have changed their names from Polytechnics to Institutes of Technology to better reflect their focus.

阿的一些理工学院也合并在一起，并改变了技术，他们的名字理工学院研究，以更好地反映它们的重点。

Here, we took demonstration study of the ecological impacts of disconnection from the river on fish recources in Zhangdu Lake. Our results showed that:(1) Fishery mode changed and the rate of wild fishery production changed from 95% in 1949 to less than 5% in 2002.(2) Fish species have decreased from 80 in 1950s to 52 at present, and the rate of migrant and potamic species decreased from 50% in 1950s to 30% at present.(3) Comparing with the linking lake, Zhangdu Lake had higher fishing production, larger individual size, fewer species number and lower diversity index of "mihunzheng" fishery, a universal fishing tool in Yangtze.

我们以涨渡湖为例开展江湖阻隔后对单个湖泊鱼类资源所产生的生态影响进行研究，结果表明：江湖阻隔导致湖泊生产经营方式改变，使得野生渔业产量的比例由1949年的95%，降低到2002年的不足5%；江湖阻隔后湖泊鱼类种类由50年代约80种下降到现在的52种，其中，洄游性和流水型鱼类比重由50%下降至不足30%；迷魂阵渔获物在单位产量、个体大小上极显著(p 0.01)地高于通江湖泊，但在物种数和多样性指数上则要低得多(p 0.01)。

It was found that the predischarge type varies clearly with relative humidity as the results of the influence of relative humidity on the field distributions.

发现，由于相对湿度对工频电场分布的显著影响，两类试品的工频预放电类型极为明显地随相对湿度的变化而改变。

In the paper, the soft of Sim for NSPK has been impoved ,and the coal burning model in the calciner and the pressure model in the NSP system have been build by using the modeling method of recognization. At the same time, The soft has been optimized to make the code and the structure of the soft more reasonable and simple. And through modeling and optimizing the soft, the dynamic simulation is realized preparatorily in the soft and it affords the condition for the real dynamic simulation.

本文修正并完善了Sim for NSPK新型干法窑系统仿真软件，根据已有的相关理论以及经验、生产数据运用辨识建模方法建立了分解炉内煤粉燃烧模型、窑外预分解系统的压力模型，规范了程序编排，并且使仿真软件能够较形象、动态地反映水泥烧成系统各参数随给定控制参数的变化而改变的过程，使仿真软件的功能和易用性大大提升了一步。

Results The hEFs were successfully isolated and cultivated from gonadal ridges and dorsal mesenteries of human embryos. They could be passaged beyond the 25th generation. The biologic characteristics of the cells did not change, even in high-passage cells or frozen-thawed cells. The cells expressed prolyl 4-hydroxylase β, but not cytokeratin-4, which was similar to the fibroblasts. The cultured cells expressed bFGF and LIF.

结果：从人胚胎生殖腺嵴和肠背系膜中成功地分离培养出hEFs，该细胞可传25代以上，且经过传代及冻存复苏后生物学特性无改变；hEFs表达脯氨酰4-羟化酶β亚单位，不表达细胞角蛋白4，确定其为成纤维细胞；该成纤维细胞表达bFGF和LIF。

With NMR and DFT methods, the Michael additions of alkynyl Fischer carbene complex with a series of substituted pyrazoles as nucleophiles were also studied. All reactions follow the same three-step pathway mechanism described above. Substituents on 3-, 4- and 5- positions of the pyrazolyl ring affect the reaction in the steric and electronic manners, even to change the rate-determining step.

一系列取代吡唑与1-炔基Fischer卡宾化合物的Michael加成反应都遵循前面提出的三步机理，其中吡唑的3-， 4-， 5-位分别从电子效应和立体效应方面不同程度地影响着反应的进行，甚至改变反应的决速步骤。

However, he caught sight of himself in the looking-glass over the hat-stand, with the rusty black bonnet perched rakishly over one eye, and he changed his mind and went very quickly and humbly upstairs to the Rat's dressing-room.

不过。他偶然从帽架上的镜子里，瞥见了自己的尊容，一顶褪色的黑色女帽，俏皮地歪扣在一只眼上，他立刻改变了主意，二话没说，乖乖地上了楼，钻进了河鼠的穿衣室。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
