Results (1) The forward and reverse subtracted cDNA libraries of different metastastic potential large cell lung cancer cell lines were successfully constructed;(2) With blue-white colony and dot blot, 307 positive clones in the forward subtracted library and 78 positive clones in the reverse subtracted library were obtained;(3) 55 clones were successfully sequenced in the forward subtracted library. Homolog analysis confirmed 23 differential expression segments, which were similar to the human genes already known, including NME2, NPM1, MT 2A, HSPE1, TAFIA, EPRS, PX19 and EIF3S9 et al;(4) 31 clones were successfully sequenced in the reverse subtracted library. Homolog analysis confirmed 16 differentially expressed segments. 15 of them were similar to the human genes already known, including ANXA2, TUBB, PKN2, GNAS, EEF1A1, SSR2 and RPLPO et al. Only one segment had partial homology to known human genes. This segment was supposed to be the new EST segments which might not have been cloned.

结果(1)成功构建人大细胞肺癌高低转移株差异表达基因正向消减cDNA文库和反向消减cDNA文库；(2)经蓝白菌落筛选和斑点杂交，正向消减文库获得307个阳性克隆，反向消减文库获得78个阳性克隆；(3)正向消减文库挑选55个克隆成功测序，经同源性分析最终确定差异表达基因片段23个与已知人类全长基因具有很高相似性(95％～100％)，这些基因包括NME2、NPM1、MT2A、HSPE1、TAFlA、EPRS、PX19和EIF3S9等；(4)反向消减文库挑选31个克隆成功测序，经同源性检索和比对最终确定差异表达基因片段16个，其中15个与人类全长基因具有很高相似性(95％～100％)，包括ANXA2、TUBB、PKN2、GNAS、EEF1A1、SSR2和RPLPO等基因。1个片段和己知人类基因仅有部分相似性，表明它可能是未被克隆的人类基因EST片段。

Which is very active and has higher electron affinities and higher electrode potential than common strong oxidant , and can react with organic pollutants in the wastewater rapidly and non-selectively. Tedder

比其他常用的强氧化剂具有更高的电极电势，且电子亲和能更高，它能快速而无选择地与废水中有机物进行反应(Tedder D W，1996)。

But the latent period for reaching the platform above the water in Morris Water Maze of the Mn-exposed group was not different from that of control group. There was a significant increase in the areas,glial fibrillary acid proteinimmunoreactivity and the average proportional densities of GFAP-positive elements in nucleus caudate and accumbens in the high Mn-exposed group, and a significant reduction in the tyrosine hydroxylase immunoreactivity and average proportional densities of TH-positive elements in substantia nigra,ventral tegmentum area of midbrain and nucleus caudate in the high Mn-exposed group.

2高剂量染锰组尾状核和伏隔核的面积、胶质细胞纤维酸蛋白免疫反应强度及反应阳性产物的平均相对密度均较对照组显著升高；(3)高剂量组仔鼠黑质、中脑腹侧被盖区和尾状核的酷氨酸氢氧化酶免疫反应强度及其反应阳性产物的平均相对密度均比对照组明显下降。

The Pratt hypothesis assumes density variations so that areas of less-dense crust rise topographically above areas of more-dense crust.

普拉特 〔地壳均衡〕假说假定地壳密度是变化的，因此认为地壳密度低的地区的地势比密度高的地区要高。

The grain yield had close correlation with the total carbohydrate.

高产良种在高氮水平积累的醣比一般品种要高得多。

Originally, higher input trigger frequency or lower input frequency for Viterbi Decoder were used to meet the transitions requirements.

因原本既有的标准，都是使用较高的输入频率来达成标准内的传输率，或者使用较低的输入频率，再用内部的PLL，提供出较高的触发频率给内部的维特比解码器来达成。

They very have also suggested that the very concept of abstract numbers - the idea of a oneness, a twoness, a threeness that applies to any class of objects and is a prerequisite for doing anything more mathematically demanding than setting a table - is itself far from innate.

他们还表示抽象的数字概念，他们还表示抽象的数字概念，如可表示任何一类物品并且是在做比摆桌子有更高数学要求的任何事时都必备的一，更高数学要求的任何事时都必备的一，三意识，远远不是天生就具备的。

But the PER is still much higher than that of existing technologies in low SNR.The high reliability of UMB system' s high data rate is also confirmed,the link level performance of UMB system is far ahead of the third-generation communication technologies.

而低信噪比下其误包率仍远高于现有技术，并证实UMB系统高数据速率的高可靠性，UMB系统在链路级性能上远远领先于第3代通信技术。

The high spectrum remote sensing further confirmed that spectrum reflectance in fenced area was higher than that in unfenced area, indicating that productivity in fenced area were better than that of unfenced area.

高光谱遥感进一步监测结果显示围栏内牧草光谱反射率比围栏外高，同样说明牧草长势及生产力围栏内要好于围栏外。

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

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
