查询词典 bed

Aiming at disjunction of microcosmic researches and macroscopical researches and status quo of theory basis researches of Aeolian sand movement near the sand bed, based on plenty of experiment data in wind tunnel, this thesis studies some microcosmic researches including the number of lift-off sand grains percent time percent sand bed area and relative movement parameters of saltating sand grains by combined methods of mechanical and statistical mechanical theories. Then, this thesis develops in advance a relation between the microcosmic researches and macroscopical researches in order to describe truly the theory model of some macroscopical physical variable of Aeolian sand movement.

本文针对当前风沙运动微观与宏观研究相脱节、准确描述近地面风沙运动规律的理论基础薄弱的现状，基于大量风洞实验数据，通过对沙床面单位时间单位面积起跳沙粒数、沙粒跃移运动过程中相关参数等微观问题的研究，力图建立风沙运动微观与宏观研究的联系桥梁，以期能够准确描述风沙运动宏观量变化的理论模型。

The number of lift-off sand grains percent time percent sand bed area Based on the lift-off velocity distribution function of saltating sand grain, this thesis gains the number of lift-off sand grains percent time percent sand bed area which ranges from 6796 to 8846900 number/(s·m2) by combination motion model of single saltating sand grain and some motion parameters of saltating sand grains and the flux of wind sand current from wind tunnel experiment.

单位时间单位面积沙床起跳沙粒数利用本文获得的沙粒起跳初速度分布函数，结合沙粒跃移运动学模型以及风洞实验中获得的沙粒跃移运动参数以及输沙量，反演出一定风场条件下单位时间单位面积沙床起跳沙粒数，变化范围6796-8846900个/(s·m2)，并满足。

It\'s also the first time to design and study the structure of new typed fluidized bed jet mill. Adding fresh air to the top and the bottom in the fluidized bed jet mill to increase the speed of upward currents, the way is leading fluidized particles to be boiling and reduce the eddy strength. The aim is to reduce the opportunity of regrinding. It is valuable to produce the particles which are rough, high density and high product rate requirement. At present, the technology has been prevailed, which produced lots of benefits for society and economy.

首次设计和研究了新型流化床气流粉碎结构，在下部和上部加入气流，提高了气流粉碎区的上升气流速度，补充喷嘴引射的气流，使底部的颗粒易于被流化沸腾起来，减少涡流强度，从而减少合格颗粒再粉碎的机率，这对较粗、密度高和成品率要求高的颗粒的加工具有极大的价值，并得到广泛的推广与应用，取得了较大的经济和社会效益。
