Secondly, it is not the same fractal diagram by the same codes of IFS to produce fractal diagram. The two graphs are extraordinary similar, but they are different in detail. The problem is researched and the algorithm which calculates the intersection points of two graphs created by the same coefficient of the IFS is proposed. The curve described changing of the intersection points number is drawn. The conclusion is that the curve fluctuates in the tiny range and is smooth when it is seen as a whole. In fact, the curve is a fractal curve.

其次，针对同一IFS迭代码两次迭代绘制得到的分形图并非完全相同这一问题展开研究，提出了IFS分形覆盖相交交点变化曲线的概念，给出了覆盖相交交点变化曲线的绘制算法，在此基础上进一步研究了分形覆盖相交交点变化曲线的变化率情况，得到了分形覆盖相交交点变化曲线宏观上比较光滑，但实际上小范围内异常波动的实验结果。

Great differences between them are found in amplitude, and attributed to the strong background wind in troposphere and steady weak wind in lower stratosphere. Steady diurnal variation of temperature appears above 23 km, and the same variation in pressure is found starting from lower altitude, which together suggest a weak diurnal variation in atmosphere density above 23 km, that approximates a constant at each height.

发现风场振幅的变化与统计平均的结果存在较大差异，这归结于当地冬季对流层内强烈变化而低平流层内相对稳定的风场；温度在23 km以上存在稳定的周日变化，气压在更大的范围内存在与温度类似的周日变化，这使得在23 km以上大气密度的周日变化十分微弱，在各个高度上近似为一个常数。

The most serious desertification occurred in southeast of MuSu Desert,then appeared inferior degree in midst,north,south and east,anddegression degree in other directions.6.The changes of environment in Mu Su Desert in historical times havebeen controlled by climatic changes in temperature and drought-wetwithin hundreds or thousands years.At present,it came into being suchspatial structure and environmental characteristics fordesertification land because of being relative to other naturalgeographic characters and human activities.In all that,physiognomyand hiemal wind are the driving factors.The sandy matter in stratumis the physical fountain factor.The depravation of surface water inthis region is one of representations of environmental changes, meanwhile,it is also the factor which leads to the degradation ofvegetation and desertification.On the whole,human activity has actedupon these natural elements,becoming a dominant factor in the regionalenvironment changes since Ming and Qing dynasty.7.Influencing of human activities on the environment of Mu Su Deserthad occurred before Qin dynasty,and its intensity of earlier influencewas so slight that it could not cause a large scope and long timeenvironmental changes.

沙漠化的程度是东南部最强，中北部、南部和东部次之，而后向其他方向递减。6、毛乌素沙地历史时期的环境变化是受百年乃至千年尺度的气候冷暖、干湿变化控制的，之所以形成目前这样的沙漠化土地空间分布格局和环境特征，则与其地的自然地理特征和人类活动有密切关系，其中地貌及冬季风是动力因素；地层中的沙物质是物源因素；地表水环境恶化是区域环境变化的表现之一，同时又是植被退化和沙漠化的引致因素；人类活动总体上是叠加在自然因素之上的，只是明清以来在局地环境变化中成为主导因素。7、毛乌素沙地人类活动的环境影响在先秦时期就已出现，早期的影响程度是轻微的，不足以造成大范围、长时段的环境变化。

A special statistic characteristic of water after deluges is turbidity. Usually the turbidity will lower to 100NTU below after one or two days, but it will take around forty days to lower to 10NTU below.

研究结果显示，由於季节变化的不确定性，净水场原水水质会出现不同变化的特性，尤其暴雨造成骤增的浊度，虽在1-2日后，浊度降至一般处理范围（100NTU以下），但需再约40-50日，浊度才会降低至经济处理范围（10NTU以下）。

In different conditions on fluidized state and stability of conical fluidized bed. The conlusions are: the conical angel of the conical fluidized bed is 20°, the fluidized state havesmall difference in conical distributor and distributor plate. The angle of conical bed increase,the fluidized state will have big difference. The angle is 60°and the conical as distributor, themass of fluidized is less, the most of material is the bottom of conical bed. The effect ofdistributor plate is much better than the conical distributor. Sawdust and rice hull can fluidize.The annular gap of conical distributor different, the angle of conical bed is same, the fluidizedquality of 10mm annular gap is better than the other conical distributors. The annular gap ismore wide, the conical bed have more slugging phenomenon and the pressure fluctuate is turnbig.In the experiment the flow of 2％and 4％distributor plates don\'t easy to control, becausethe pressure is very big and the pressure fluctuate of conical bed is too big.

在不同的条件下对锥形床的流化状态和稳定性进行了研究，结果得出：锥形床的锥角为20度时，分布锥和分布板的流化状态相差不明显，随着锥形床锥角的增大，分布锥和分布板的流化现象会出现明显的变化，锥形床锥角越大，分布锥的流化状态变化越明显，流化的的物料越少，大量物料都聚集在锥形床底部，而分布板在加料量少的情况下，能流化起来。10mm、15mm和20mm环隙分布锥在锥形床锥角相同条件下，10mm环隙分布锥的流化质量要好于其它两个分布锥，环隙越大越容易出现腾涌现象的产生，压降波动范围增大。2％、4％和6％开孔率分布板在本实验测定时，2％和4％开孔率分布板的流量不容易调节，同时产生的压降波动范围也很大，比较来说，6％开孔率分布板流化质量好些。

5Ns. The peak position of N band emission as well as the distinct emission region slightly moves towards the open end of the cylindrical cavity, and this does not happen to O band emission. Radiation transport efficiency of 6% is obtained for the φ400×1200um cylindrical cavity heated by x-ray source with radiation temperature of 118 eV.

从时间分辨的X光强度轴向空间分布来看，在较长时间（约1～1.5ns）内，O带X光在整个观测缝对应的轴向范围之内均有较大的辐射强度，在X光强度空间分布的变化过程中，其强度峰值的空间位置基本不变；而对N带X光，则只在较短时间（约0.5ns）内，在整个观测缝对应的轴向范围之内可观测到X光辐射，但只在靠近输运源约300μm的范围内有较强发射，在柱腔末端600～700μm范围之内的辐射则很弱，N带X光辐射轴向空间分布曲线的峰值位置在朝柱腔末端的方向移动，移动量大约为130～250μm。

At the same time, the biomass of species-rich community was more sensitive to the change of environmental conditions, while communities with fewer species had a little change in biomass.2 There were a total of 87 vascular plant belonging to 27 families and 68 genus in the six communities. Most species had a narrow distribution and a lower local abundance, while few species had a wider range and higher local abundance, and this distribution trends varied in different communities. The endemics were positive correlation to y diversity.
