查询词典 velometer

The velometer is assembled with TTL integrated circuits.

仪器全部采用TTL集成电路组装。

Compared with other available instruments the velometer has the advantages of highly automatic operation, rapid response, flexibility and relatively much lower cost. 2 Sequential flow is the most important function of a step gating system. Till now the studies about it have given little information.

针对以往关于阶梯浇注系统研究中，对各层内浇口分层注入功能研究不够，缺乏定量测量结果的不足，本文工作中采用微计算机化的光电非浸入式流速测量仪，首次实现了对几种典型的阶梯式浇注系统各层内浇口流速在浇注过程中变化情况的动态测量。

Flow visualization and laser velometer measuring results show that the radialdistribution of turbulent intensity and turbulence stresses grow with the increase of voidfraction until large vortex formed near the pipe wall,and the formation of Taylor bubbleor the coalescence of bubble cluster should be restrained by intense turbulence.

流动显示和激光测速计的测量表明，湍流强度和湍流应力的径向分布均随空隙率的增长而迅速增长，直至在近壁形成大尺度涡结构，使Taylor泡的形成或气泡群的聚并被强湍流的作用抑制。

Because of the indispensability of such dynamic measurement in simulating investigations of step gating systems, first of all, the paper describes an innovation-a computerized photoelectric non-invading velometer.

该仪器采用微型单板计算机作为中心控制单元，采用光电传感器采样，实现了对水力学模型中流体流动的非接触测量。

The Red Sea has used the diameter is the 9cm static figure radiation ventilator, but pursues the static sound to play the family to be possible to purchase a ventilator velometer, the hand control ventilator's rotational speed adjusts between 1200-2200 rpm, ventilator's noise is also is situated between 15-25db10% differently according to the rotational speed, both has satisfied the radiation request, and may according to user's need, the adjustment wind speed realize the user static sound demand.

红海采用了直径为9cm的静音型散热风扇，不过追求静音的玩家可以购买一个风扇调速器，手动控制风扇的转速在1200-2200 rpm之间调整，风扇的噪音也是根据转速的不同介于15-25db±10%，既满足了散热要求，又可以根据用户的需要，调整风速来实现用户静音的需求。

Results of economical analysis on 6 modified furnaces in Qian′an,Fengrun and Baodi Stations show that 502116kW·h of electricity can be saved annually by using frequency conversion velometer,an investment of RMB250000 can be saved,and the payback period is around 1 year.

对改造后的迁安、丰润、宝坻3站6台加热炉进行经济分析可知，采用变频调速器，全年可节电502116kW·h，节约投资25万元，回收期约1a。
