drop height meaning in English
空投高度
Examples
- In the present research the fiber - like palygorskites are surface - modified by four kinds of different coupling agents , and the optimal modification process parameters are obtained by the drop height method employed to evaluate the effects of surface modification
摘要分别采用四种不同偶联剂对坡缕石进行表面改性，用沉降高度法对改性效果进行评价，得到了四种偶联剂表面改性坡缕石的优化工艺。 - So according to the technology regulation of reclamation engineering , hydraulic calculation must be carried out in the design of final closure . this paper firstly introduces the progression and present situation of reclamation engineering , emphasizing on the features of present reclamation and on the experiences and theories of home and abroad ; using fortran perfects the hydraulic calculation program of the closure and makes the program to meet different conditions ( such as considering flood , the variation of time interval , multi - entrance , multi - reservoir capacity ) , and after comparing and analyzing a great deal of schemes , the reasonable computation scheme was brought up ; the interface of the program was carried out by the programming language vb to make the process of calculation become easier and more distinct , so the result can be analyzed and handled more directly ; vb is used in the later management of the result to plot the graphic chart of the isoline of the maximum of hydraulic element ( the velocity of flow , the drop height and the rate of flow ) automatically ; finally it was applied in the reclamation project of dongbidao of fuqing
本文首先介绍围海工程的发展进程与国内外围海的开发现状，重点介绍了我国目前围海工程的特点及在围海工程实践中积累的经验和理论；利用fortran语言完善堵口工程龙口水力计算程序，使程序可以满足围海工程复杂工况下(如考虑内港洪水、计算时段的变化、多口门、多库容、多水闸)的龙口水力计算，并进行大量方案的比较和分析，提出合理计算方案；利用面向对象的可视化编程语言vb进行界面开发，使计算过程有良好的人机界面，更直观地对计算结果进行分析和处理；计算结果的后处理采用vb编程实现龙口水力要素最大值等值线图的绘制；并运用所编软件对福建省福清市东壁岛围垦工程进行龙口水力计算，为堵口合龙提供科学依据。 - Seawall and sluice are the parts constructed in advance , while final closure is the last part in construction . the hydraulic condition during the final closure process is worse than that during any other processes . and with the compressing of the entrance , the hydraulic condition becomes badly , the drop height of entrance can reach 2 to 3 meter , the maximum velocity of flow even reaches 6 to 8 meter per second and flow condition also becomes complex
海堤和水闸的修建都是围海工程先期施工的部分，堵口则是海堤修筑的最后阶段，堵口合龙成败关系到围海工程成败，由于此阶段所遇到的水力条件十分恶劣，口门落差可达2 3m ，流速最大可达到6 8m / s ，且水流极其复杂，根据我国《围海工程技术规范》规定围海堵口必须进行龙口水力计算。
