At the same time, data of welding transverse contraction deformation offered reference for machining of welding structure. 焊接中测量的焊接变形,为焊接结构的加工提供了参考数据。
With the exclusion of transverse expansion or contraction joints of Portland Concrete Pavement, CRCP has more advantages including better riding quality, higher bearing capacity, longer service life and less maintenance work. CRCP消除了普通混凝土路面的横向接缝,具有行车舒适性好,承载能力高,使用寿命长,养护维修少等显著优点。
Joint-cutting Method Applied in Transverse Contraction Joint of Concrete Pavement 混凝土道路面层横向缩缝应采用切缝法施工
We also measured the rate of bile flow of the spleen-asthenia white rat. Results: Gallbladder of spleen-asthenia rabbits has the characteristics of small transverse diameter, reduced tension, thin and long in shape, and the contraction rate of spleen-asthenia white rat become little. 结果:脾虚兔之胆囊呈现横径小、张力差、体细长及收缩率低的特征,脾虚大鼠胆汁流量少。
Under the same temperature and the chamber pressure, hypergolic ability of transverse injectors is better than that of the gas/ liquid coaxial injectors. Hypergolic ability tends to improve with higher nozzle contraction ratio. 在相同温度和室压下,横向喷注器的自燃能力优于气液同轴喷注器,喷管收缩比越大,越利于自燃。
Methods: the transverse and longitudinal contraction role of smooth colon muscle strips at the different dosage of TGP and other medicine was separately observed. 方法:制备豚鼠结肠纵肌和横肌肌条,观察不同剂量白芍总甙及工具药对离体结肠肌收缩活性的效应。
Wind cooling accelerated elimination of heat dissipation, and controlled temperature which made welding transverse contraction deformation and the residual stresses decrease. 气冷的方法,可以使试样散热更快,达到控制温度的目的,同时也可以减小焊接残余应力和焊接横向收缩变形。
Analysis shows that the out-of-plane distortion of weld fixed at one end is produced by angular distortion caused by transverse shrinkage and longitudinal bending caused by longitudinal contraction jointly, and that of longitudinal restrained weld is mainly produced by angular distortion caused by transverse shrinkage. 结果表明:一端固定的焊缝平面外变形是由横向收缩引起的角变形和纵向收缩引起的纵向弯曲共同作用的结果。
The results showed that compared with normal welding, vibratory welding made the residual stresses and welding transverse contraction deformation decrease. 结果表明,和常规焊接相比,振动焊接不仅可以使焊接残余应力下降,而且也可以减小焊接横向收缩变形;
The transverse and longitudinal contraction role of colonic smooth muscle strips of 11 Chinese herbal medicines and other medicines was separately observed. 制备大鼠结肠纵肌和横肌肌条,以生理盐水和乙酰胆碱为对照,观察11味中药对离体结肠肌收缩活性的效应。
Transverse contraction distortion was added with the increase of heat input. Longitudinal distortion was reduced significantly compared with that without vibratory acceleration. 横向收缩变形随着焊接热输入的增加而增加,纵向收缩变形较常规焊接下的明显减小。
At last, as the heat in the metal around weld bead is nonhomogeneous during the welding process, it causes the unhomogeneous transverse contraction along the thickness of the steel ring, which may lead to the angular distortion and the distortion of the roundness. 最后,焊接时近缝区金属由于加热不均匀,导致横向收缩沿钢圈厚度上分布不均匀而产生角变形,从而使圆度发生变化。
The angle deformation of the reinforced structure is decided by the temperature gradient of the structure thickness and the weld transverse contraction. 加筋结构的角变形是由焊件厚度方向的温度梯度和焊缝的横向收缩两方面决定的,且焊接顺序和焊缝长度对焊接残余应力与变形也有很大的影响。
