From the industry to observe,the author discovers that the regional gap of the secondary industry was the primary contributor,but the rate of was descending.The third industry was becoming the important contributor.The industry structure adjusting and the agglomeration of the third industry and the secondary industry are the primary reason of the forming of the disparity of between the east and the rest areas.In the 1978 to 2005,the absolute convergence of economic growth didn't occur,the other way round,the club convergence of economic growth occurred in the east and in the middle.The speed of the economic growth in the east was higher about 1 centigrade than the middle and the developing west,and was higher about 2 centigrade than the west.

从以省区为单元的中国地区经济发展差距形成的产业构成来看，第二产业的地区差距长期以来都是中国地区经济发展差距的主要贡献者，居主导地位：但是随着第三产业产值比重的提高和第三产业地理集聚的非均衡性扩大(1990年以后)，第三产业的地区差距正逐渐演变为以省区为单元的中国地区经济发展差距形成的主要贡献者。1978-2005年期间，中国地区经济增长并没有出现绝对收敛趋势，而是表现为东中部地区内部的"俱乐部"收敛。1978-2005年东部地区经济增长速度比中西部地区更快，东部地区平均经济增长速度比中部地区高1个百分点左右，比西部地区高接近2个百分点，地区间经济增长速度存在显著的差异。

The most feature of the orbits of Near Earth Asteroids is that the semi major axes of the orbits are nearly equal to that of the Earth or the perihelia distances are approximate to or even less than the mean distance between the Sun and the Earth,thus they could move into inside of the Earth's orbit,so that th...

近地小行星轨道的最大特点是其轨道半长径与地球轨道半长径相近，或近日距离接近甚至小于日地平均距离，其运动可深入到地球轨道的内部，这将导致该类小行星与地球十分靠近甚至发生碰撞。

Fruit weight was significantly increased by 33 g or 79 g through half-tree of three out of four flower cluster thinning,consequently fruit calcium concentration was decreased by 1.62 or 2.66 mg/100g fresh weight respectively,it means that fruit calcium concentration was significantly affected by the treatments that significantly altered fruit size.

By using the NCEP/NCAR (National Center for Environmental Prediction/National Center for Atmospheric Research) reanalysis of daily with the horizontal resolution of 10°×10°(lat./lon. grid), the representative Pacific area (0°～ 60°N, 160°E～120°W) in northern hemisphere summer is chosen to analyse the 3D wind field, according to which the mean meridional circulation of the lower and middle latitudes, especially the Ferrel cell, is studied and a new concept model of Ferrel cell is carried out. Compared with the classical model, the new one describes more precisely the low and high level winds and has the ability to describe how the westerlies sustain on the real rotating Earth.

Diamonds began growth when "Jiangnan continent" combined to Yangtze craton, the growth and residence average temperature T〓 was about 1200℃; Diamonds were mutil-stages growth and interruption caused by temperature and pressure varied during Yangtze craton activities; Diamonds were etched when the magma did not erupt on the surface and form failed magma in mantle; during the later growth term T〓＜1050℃, the type ⅠaA diamonds formed unclear and growth; Before the host magma erupted T〓＜0.5Ma, T〓A＜850℃, the type Ⅰb diamond formed unclear and growth; Few diamonds were brittle deformation during growth term, some were plastic deformation after growth; when the host magma erupted on the surface and weathered to alluvial deposit, diamonds surfaces formed green spots caused by irradiation, then most of green spots became to brown spots during a mid-temperature metamorphism; modern river reform it to alluvial deposit in the minute valley again.

在扬子地台&江南古陆&克拉通化时，金刚石开始生长，其生长与保存的平均温度T〓在1200℃左右；期间由于地台的活动，生长的温度压力条件发生了多次变化，使金刚石出现多次生长、停顿；夭折的母岩上侵活动使金刚石受到熔蚀作用；在金刚石形成的晚期，T〓值下降到1050℃以下，出现了另一次金刚石的生长期，在临近金刚石母岩上侵时T〓＜0.5Ma，温度进一步降到850℃以下，使Ⅰb型金刚石得以保存；在金刚石形成期间还有过碎性变形发生；金刚石形成后部分样品经过了塑性变形；金刚石在上侵过程中，遭受了强烈的熔蚀；在母岩露出地表，形成沉积砂矿时，受到了放射性物质的辐照，先形成表层的绿色斑点、壳层，后经过中低温的热变质作用，大部分绿色转化为褐色；现代河流作用对沉积砂矿进一步改造，形成现在的细谷型砂矿。

Second, wetland landscape pattern dynamic change of Kenli County Take TM as the information source, according to studies the region wetland ecosystem present situation characteristic, wetland is divided into 10 kinds: irrigation paddy field, pit pond water surface, cultivation water surface, artificial ditch, reservoir water surface, salt field, rivers water surface, reed, shallow seas and tidelands, beach. The wetland landscape area is remarkable dropt from 1987 to 2004.In 1987 the wetland area occupied 14.10% of Kenli county, but only was 12.33% in 2004, it reduced 6155.12 hm2 in 17 years and average reduced 362.07 hm2 every year, the reduction scope of shallow seas and tidelands wetland is biggest 3894.78 hm2. The shallow seas and tidelands and reed are frequent transformation with other type.

2查清了研究区湿地景观格局动态变化规律以TM影像为信息源，根据研究区域湿地生态系统现状特征，把垦利县湿地分为10类；湿地景观面积在研究时段内呈显著下降趋势，1987年湿地面积占整个研究区总面积的14.10%，但到2004年只占12.33%，17年共减少6155.12 hm2，平均每年减少362.07 hm2，其中滩涂湿地面积减少幅度最大3894.78 hm2；从各湿地类型之间的转换来看，各种湿地景观之间、湿地和非湿地之间相互转化和逆转并存，滩涂和苇地与其他地类转换频繁；研究区湿地景观斑块数量增多，景观多样性指数1987年为1.7643，2004年下降到1.7105，均匀度指数由1987年的0.6873上升到2004年的0.6923。
