平板试验 meaning in Chinese

treadmill test

On basis of numerical simulation , the optimized weling technological has been vadidated and adjusted by plane test , results show that residual stress of both ends welded in advance can be decreased by the interspace welded later , and decreasing effect is the most obvious in the 50mm range of the interspace ; for local heating , it is 60mm from the edge of heated area to decrease residual stress
通过平板试验得到了分段焊与局部加热合理工艺参数,并在此基础上,对转轮的焊接残余应力场进行了调整与控制,使叶片出水边危险区域附近产生了较大的残余压应力,且转轮整体的残余应力水平低于转轮材料屈服极限的三分之一。
Through flat experiment and circle experiment , we research the causes of cracks before hardening of concrete and after . through ingredient experiment , we research the influence of shrinkage from some ingredient ( coal ash , crushed stones and fiber ) . in addition , we test some methods of construction to strengthen the anti - crack capacity of r . c . slab in building sites
通过平板试验和圆环试验，研究了混凝土在终凝前和终凝后裂缝的各种影响因素；通过掺合料试验，研究混凝土的一些掺合料(粉煤灰、碎石和纤维)对其收缩变形的影响；另外，还在施工工地进行一些增强楼板抗裂能力的构造措施试验。
