The coupling of low - level ( convergence area lay ahead of jet on the left ) and upper - level ( divergence area lies rear of jet on the right ) jets played an important role in the course of vertical motion developing 高空急流入口区(右后方)的辐散，与低空急流左前方的辐合区互相耦合，对垂直运动的发展起到很大作用。
Through the analysis of the deduction process of harmonic function model , it is illustrated that some hypotheses in the deduction process are unreasonable and the harmonic function can not reflect the objective regularity of the vertical crust movement , so that it isnt an effective method to compile isoline map of the vertical crust movement rate 对有关文献提出的“地壳垂直运动调和分析”模型的建立过程作了全面分析，指出：该模型建立过程中所做的一些处理是不合理的，由此建立的模型不是地壳垂直运动规律的客观反映，因而尚不足以成为编制地壳垂直运动速率面等值线图的可靠手段。
In fifth chapter , analysis of reducing required power supply and running energy consumption are the main research contents . according to test hydraulic elevator rig , the following contents are completed : firstly , comparison with traction elevators , the research on required power supply and energy consumption are presented . secondly , research on energ Os纵观全文，本论文圆满地完成了预期目标，成功实现了首次提出的采用蓄能器降低液压电梯装机功率以及能耗的新方案；本论文的研究成果不但是液压电梯的重要发展方向之一，而且在其它垂直运动机械中也具有广泛的应用前景。
To improve dynamic performance control effect for air suspension vehicle with half vehicle model as a control object and perpendicular motion and longitudinal acceleration as control indexes , the half - vehicle model fuzzy control simulation was performed by taking grade b road as random input 摘要为了改善空气悬架客车动态性能的控制效果，以空气悬架客车1 / 2模型为控制对象，以车身垂直运动和俯仰运动加速度为控制指标，以b级路面为随机输入，应用模糊控制技术对1 / 2车辆模型进行了计算机控制仿真分析。
The main results are as follows : ( 1 ) the evolutionary features of precipitable water in the whole troposphere in northwest china are different between over the east region and over the west region during the past 50 years from 1951 - 2000 : in the 1990s " the pv in the east of ncw is evidently decreased , and the scope of the descent is the largest one in the same latitude over the north - hemisphere , on the contrary , which in the west regions showed increasing trend 最后，分析了近50年来西北地区东部垂直运动强度的年代际变化特征。主要得出了如下结论： ( 1 )西北地区东、西部对流层整层大气可降水量在1951 - 2000年近50年来表现出不同的变化趋势： 90年代以来，东部明显减少，而西部有所增加，且东部减少的幅度在北半球同纬度地区最大。
We can use the mm5 model in definite time , definite area weather forecasting . we conclude that : : the moving route of this necw in its developing progress was direct - south along latitude , the cold air is rough , and just this made the rough vertical velocity ; the necw southern moving and conflicting with the west pacification sub - tropical high makes rough jet steam . the plenty south - west warm and wet air made by the jet stream gave the rainstorm demanded vapor ; . the rough vertical velocity by jet stream is a main reason in this rainstorm ; the mm5 model uses four - direction analysis data as its input , this avoids some errors occurred in observe and transfer , thus made the result more useful 综合分析认为： ( 1 ) 、这次冷涡在其发生发展过程中，其移动路径是沿经圈直线南压，携带的冷空气势力较强，形成槽后较强的垂直运动； ( 2 ) 、西太平洋副热带高压偏北位置与东北冷涡南压形成的急流轴，把源源不断的西南暖湿气流输送到辽西地区，也就是急流轴的左前方位置，为这次暴雨的产生提供了充足的水汽来源； ( 3 ) 、低空急流不但为暴雨输送水汽，其造成的较强的垂直环流也是产生强降水的一个主要原因； ( 4 ) 、 mm5模式以四维同化资料作为初始场，最大限度地避免了观测误差可能造成的积分不稳定，提高了模拟结果的参考价值。
The regional deformation anomaly of medium - term phase ( 1 ~ 3 years or more ) before strong earthquake occurrence usually shows three aspects of common characteristics : for regional vertical deformation , it shows distribution features of anomalous uplift area and concentration belt - high gradient belt of vertical differential deformation ( some of them reflect distribution of four quadrants ) related to tectonics ; for horizontal movement , it shows features of centralized high strain area ( or zone ) of domination shear deformation related to active blocks and faults ; it shows common features of regional vertical deformation anomaly area and high strain distribution area of horizontal deformation 摘要强震前中期阶段（ 1 ~ 3年或稍长）区域性形变异常往往表现出3个方面的共性特徵：区域垂直运动变形呈现与构造有关的异常隆起区、垂直差异变形高梯度带（有的还呈“四象限” ）分布特徵；水准运动变形呈现与活动地块及断裂构造有关的、以剪切变形?主的高应变集中区（带）特徵；区域性垂直形变异常区与水准形变的高应变分布区共性的特徵。
Qingtongxia irrigated area , located in the hetao area of ningxia hui autonomous region , has had more than 2000 years pumping water from yellow river irrigating because there is an arid region , evaporating strongly , the groundwater depth of burial being shallow , especially in yinbei region , the perpendicular motion of groundwater being fairly acute , and the salt content of groundwater being detained in soil , which caused the soil salinization 青铜峡灌区位于宁夏黄河河套地区，已有两千多年的引黄灌溉历史，由于灌区地处温带干旱地区，蒸发强烈，地下水埋深浅，特别是银北段，地下水的垂直运动比较剧烈，地下水的盐分滞留于土壤中，造成土壤盐碱化。
