Examples
- Please store it in a dry and cool area after opening , avoiding damp
3开封后请及时封闭袋口，置于阴凉干燥处，以防受潮。 - Store in dry , cool area and keep them out of director sunlight and away from water
保存在干燥阴凉的环境中避免阳光直射和水浸。 - The mechanized covering with plastic film is the effective way that maizeincreases production at cold and cool area
机械化地膜覆盖是冷凉地区玉米增产的有效途径 - If exertion in the heat makes your heart pound and leaves you gasping for breath , stop all activities , get into a cool area , or at least in the shade , and rest , especially if you become light - headed , weak , or faint
如果在天气酷热时活动，感觉到心脏急跳并且开始喘气，尤其是觉得头晕、无力或虚弱，你应立即停止所有活动，寻找一个凉爽的地方或者在有遮阴处休息； - The welding technology of francis turbine runners is optimized from the view of subsection welding and local heating by numerical simulation . the result shows that welding residual tensile stress appears in the weld and its area nearby , and peak stress appears in the dangerous area of blades after practising quondam welding technology ; welding residual tensile peak stress in the dangerous area of blades can be decreased by welding both ends earlier and then welding middle section later during subsection welding , and decreasing effect on welding residual stress of the subsection welding is related to the weld length of blade outlets and welding direction of each subsection ; decreasing effect on residual stress of the local heating is direct proportional to heating time , heating temperature , heating area , and inversely proportional to cooling area , and welding residual tensile peak stress in the dangerous area is decreasing trend earlier , and then increasing trend later with heated location increased
本文利用数值模拟手段对转轮的焊接工艺从分段焊和局部加热两个方面进行了优化,结果表明:采用普通工艺焊接时,叶片焊后残余拉应力出现在焊缝及其附近区域,并且在叶片出水边的熔合线附近(危险区域)出现了峰值;在采用优化的分段焊时,先焊两端后焊中间的方法可以降低叶片危险区域的焊接残余拉应力峰值,降低效果与叶片出水边焊段长度、焊缝各段的焊接方向有关;局部加热法降低转轮危险区域残余应力的效果主要与加热时间、加热温度以及加热面积成正比,与冷却面积成反比,并且危险区域的残余应力随加热区域的增大呈先降低后升高的趋势。
