This paper has studied the impacts of rubber plantation on the fragmentation of tropical forests and its substitution for natural forests.

研究表明：西双版纳橡胶种植既有明显的地域分布和地带分布差异特征，也有很高的时空动态度；橡胶种植对土壤侵蚀作用不明显，但是使周边环境破碎度加大，热带森林异质性自然景观向单一人工斑块化景观发展；西双版纳橡胶种植获得了巨大的社会效益和经济效益，也对热带森林的稳定性和多样性造成威胁。

The pluton has abnormally high concentrations of Sr and high concen trations of Ba,especially low concentrations of rare earth elementsand strong positive Eu anomaly,which are striking different from other calc-alkaline rocks with similar SiO 2 concentrations.

地球化学方面以异常高的Sr含量和较高的Ba含量、极低的稀土元素总量、明显的Eu正异常为特征而明显不同于SiO2含量类似的其他钙碱性岩类。

The results show that the type of Qingdao's economic growth is promoted by capital and the output elasticity and contribution rate of human cap- ital are low,while the spillover effect of human capital is not clear.

结果表明，青岛市的经济增长带有明显的资本推动型特征，人力资本的产出弹性和贡献率较低，溢出效应不明显。

Karyotypes of root tip chromosome showed that the arm volume ratio, the mean relative volume and idiogram were identical before and after improving seed vigor, so the pattern of chromosome did not change. But we couldnt confirm whether the pattern of other separation dates and the inner structure varied in this experiment, such as gene mutation.

根尖染色体核型分析结果，甘蓝种子在活力提高前后染色体的臂比值相同，相对长度相同，表明活力提高后染色体在形态及核型上无明显变化，而对于除中期外的其它分裂期染色体的形态特征以及染色体内部结构有无明显变异在本试验条件下尚不能确定。

It analyzes the effects of the pollution severity and the altitude or atmospheric pressure on the flashover voltage or the flashover gradient. It is shown that FOV is determined by the configuration, and the insul...

结果表明：合成绝缘子的污闪电压与伞裙结构有密切关系；在同样的最短干弧距离下，简单伞形结构的合成绝缘子具有更高的污闪电压和污闪梯度，对于伞形结构复杂的合成绝缘子，虽然其爬电距离提高了，但其污闪电压没有明显提高；高海拔下合成绝缘子的气压影响特征指数n大于瓷和玻璃绝缘子，并受伞裙结构形式、污秽程度的影响，且随着污秽程度增加，n逐渐减小，此外，染污方法和方式对n也有一定影响但不明显。

The bulk transfer coefficients change during a day, reach the maximum at noon and the minimum at night.

总体输送系数具有明显的日变化特征，中午时段最大，夜晚最小；总体输送系数与大气稳定度存在明显关联，文中给出它们之间的拟合关系式；随着高度的增加总体输送系数减少，但减少幅度逐渐变小。

The measurements in the ship tank and the wind tunnel show that there are no obvious differences between the mean profiles of turbulent boundary layers at the rigid wall and the compliant wall, but the turbulence intensity of the turbulent boundary layer near the compliant wall is higher than that near the rigid wall.

中文摘要：船池和风洞的热线热膜测量表明，刚性表面和柔性表面湍流边界层的平均速度型无明显差异，但柔性壁面的湍流边界层的壁面附近有较高的湍流强度；两者的相干结构有明显的不同特征。

Based this better correlation and using the multiple regression method, we reconstructed the historical spring and summer flood/drought index from 1835 to 1996. The reconstructed series shows obvious decadal variability, and thus provides a reliable reference for the local climatic change study.

根据此显著相关性，利用多元回归方程重建了历史时期的春夏季旱涝指数，分析表明天目山地区春夏季旱涝的发生具有比较明显的年代际变化特征，为研究该地区气候变化特征提供了较可靠的参考依据。

This paper conducts the computation classification for the spring flood and drought situation in He Zhou by using the spring precipitation data in four weather stations of He Zhou during 1965-2004,and the z index,and the index of regional flood and drought .

利用贺州市四站1965~2004年春季降水资料，运用z指数和区域旱涝指数对贺州地区春季旱涝情况进行计算分类，并对重旱涝典型年份500hPa环流特征量和4月平均环流场展开分析，发现：贺州地区春季极易发生局部旱涝灾情，90年代以来重旱涝年份出现频率明显增大；在重旱年副高强度强，西伸脊点明显偏西，南支槽偏西偏弱，极涡中心偏东，亚洲中高纬高度偏低，在重涝年则相反。

The steppe landscape is dominant but not apparent in its patch and area, and the percentage of the original vegetation of Stipa bungeana steppe is very low in the study area, which is apparently characterized by human disturbance. The diversity and evenness of patches in the study area are higher than those of the steppe landscape area, and the fragmentation and the isolation of the steppe are the highest. The landscape shapes of artificial arbor woods and cultivated lands are the simplest, and the landscape shapes of classical steppe and artificial shrub are in an instable stage.

结果表明：(1)草原景观在其斑块数和面积上虽然仍居首要地位，但其优势并不十分明显，而且该区原生植被本氏针茅草原只占很小的比重，呈现出非常明显的人类干扰特征；(2)研究区斑块的多样性程度和均匀度较高，而面积的多样性程度和均匀度较低，同时，典型草原的景观破碎度最大，景观分离度也最大；(3)景观形态上，人工乔木林和耕地的景观形态最为简单，典型草原和人工灌丛这2种景观类型还处于很不稳定的阶段。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
