Generally , the maximum tangential compressive strain was 2 ~ 4 times of vertical and radius - orientation direction 环向最大压应变一般为同一监测层位竖向、径向最大压应变的2 ~ 4倍。
Safety of the shaft wall was discussed taking into account of ultimate compressive strain of high strength concrete ( hsc ) 结合高强混凝土的极限压应变,分析了井壁结构的安全性。
The maximum tangential compressive reaches 2221 , which is about 76 . 6 % of the ultimate compressive strain , within safe status 在龙固副井施工中,井壁环向最大压应变达2221 ,约为极限压应变的76 . 6 % ,处于安全状态。
Objective . to determine the apparent glucose diffusivity in 2 directions ( axial and radial ) of bovine af under 3 levels of compressive strain ( 0 % , 10 % , and 20 % ) 目的:测定牛纤维环在低于3个等级( 0 % , 10 % ,和20 % )的压缩应变下在2个方向(轴的和辐射的)上葡萄糖的近似扩散系数。
The study proved that tensile strain arose firstly in the outer shaft wall after it ' s building , then decreased gradually with decreasing of temperature , finally , it converted to compressive strain 研究表明:外层井壁浇筑后,混凝土首先产生拉应变,而后随井壁温度下降而逐渐减小并转变为压应变。
For strained si pmosfets , the hole mobility is not only determined by the tensity of strain , but also related to the strain types , which are uniaxial compressive strain and biaxial tensile strain . when electric field is high enough , the hole mobility will be deteriorated in pmosfets under biaxial tensile strain , however , in the case of uniaxial compressive strain , the deterioration will never occur 经模型分析发现,应变硅pmosfet空穴迁移率与应力作用方式有如下关系:当横向电场较高( > 5 105v / cm )时,双轴张应力作用下的应变硅pmosfet的空穴迁移率将发生退化,而单轴压应力器件则不会受到影响。
Here the hsc of sompa is achieved through adding super - effective water reducer , fined slag and silicon fume , and decreasing the water / cement ratio . by varying the area ( spacing ) of tension bars , compressive bars , vertical links and distribution steel and embedding steel fiber and polypropylene fiber we try to improve the behaviors of reinforced high performance concrete one - way spanning slabs in bending , so that its ductility be greater than 5 . with the same arrangement of steel the width of bending member is varied to observe the effect of the width / depth ratio on the ultimate compressive strain of concrete 通过变化受拉筋含筋率和受压筋、箍筋(钩筋、分布筋)含量,或掺加纤维使之成为钢纤维高强混凝土( sfrhsc )和聚丙烯纤维高强混凝土( pfrhsc ) ,对高强混凝土双筋截面梁、板的受弯性能进行了试验研究,试图改善高强混凝土受弯构件的延性,使其延性比大于5 ;并在相同配筋情况下,通过变化截面宽度,研究了高强混凝土受弯构件的宽高比对压区混凝土极限应变的影响;并对试验构件的裂缝发展情况进行了观测。
