The results of the experiment are in good agreement with the data of theoretical calculation and the actual conditions of earthquake calamity . these data and information give a convenience for the following work . the finite element analysis ( fea ) has been completed within the environment of ansys 有限元分析主要以ansys为工具对烟囱进行了动应力计算，得出了在不同地震波水平和竖向激励下动应力随高度分布情况，并据此绘制了动应力随高度变化曲线图。
Multi - span plastic greenhouse structure design theory has been studied systemic which include design loads , design methods and system optimization designs aimed at the situations above - mentioned , meanwhile , theory analysis and designs have been completed for series east - china multi - span plastic greenhouses in accordance with the local climate characteristic . some elementary conclusions are summed up : ( 1 ) in the aspect of multi - span plastic greenhouse structural design loads researches , based on the contrast analysis of loads provided in foreign and chinese standards , analysis and discussion are mentioned about the definition loads , the estimation and load cases for multi - span plastic greenhouse structural design in details , some conclusions are summed up first : i , wind load : under the present conditions , it is unnecessary to 得到一些初步的结论： ( 1 )在连栋塑料温室结构设计荷载研究方面，从分析比较国外关于温室建筑及我国工业与民用建筑设计荷载规范的角度出发，针对连栋塑料温室结构设计中的荷载定义方法、计算取值、荷载组合等进行了较深入的探讨和分析，首次得到以下结论： 、风荷载：在现有条件下，考虑风压高度变化系数、阵风作用因子和风荷载体型系数，按中国建筑结构荷载规范( cbj9 ? 87 )计算风荷载是可以的，不必进行重现期博士学位论文摘要修正。
An atmosphere structure constant cn2 model , which varies with height , is presented based on itu - r amplitude scintillation model , existing itu - r optical cn2 model and meteorologic measurement relative humidity and temperature profile data , at 10 ~ 30ghz . the log - amplitude scintillation deviation calculated in terms of the cn2 model based on humidity and temperature vertical profile compare with values predicted by means of itu - r and ortgies model . it is emerged that the calculation results based on the cn2 model agree almost with prediction results by itu - r and ortgies model at 10 ~ 30ghz and there is an advantage that relative humidity and temperature varied with height has be considered in the cn2 model 根据光波段的itu - rc _ n ~ 2模型， itu - r幅度闪烁标准偏差模型，和温度和相对湿度随高度变化的气象数据，在10 30ghz ，分析得到了大气结构常数c _ n ~ 2随高度变化的模型；并根据温度和湿度垂直分布数据计算了对数幅度闪烁_ x ，还与itu - r和ortgies模型的预测结果进行了比较，结果表明，在10 30ghz ，用该c _ n ~ 2模型计算的结果和用itu - r及ortgies模型预测的值符合较好，且在用c _ n ~ 2模型计算时考虑了温度和相对湿度随高度变化关系。
The seasonal cycle and interannual variation of sea surface height from topex / poseidon and ers - 1 / 2 are analyzed in tropical pacific and indian oceans in this study , and they are compared with those from a coupled climate model fgcmo in order to assess the ability of the model to simulate seasonal cycle and interannual variation in sea level height 本文利用卫星海面高度计资料，分析了赤道太平洋和印度洋海面高度变化的季节和年际变化特征，并与一个耦合气候系统模式fgcmo模拟的海面高度进行比较，评估模式模拟海面高度季节和年际变化的能力。
