Sinusoidal profile and triangular profile are chosen as the bottom profile , and the undulated profile varies periodically . newtonian fluid and non - newtonian fluid are considered in each flow model 选取两种波形底板模型:一种为正弦板基面;另一种为三角板基面,其轮廓曲线分别为周期变化的正弦和三角形曲线。
The four situations in the three basic projection planes are the only certifications to produce the direction and location , those who think that in these four situations projection planes may surplus is wrong 摘要三基面体系中的4种情况是形成方向和位置唯一固定的依据,证明了那种认为此4种情况中基面存在超越和重复的观点是错误的。
2 we studied the films with raman polarization spectrum . the peak intensity in the polarization spectrum of the films with basal plane not oriented on the substrate changes with the polarization condition 张生仅北京工业大学博士学位论文摘要2利用raman偏振光谱研究了薄膜的性质,对基面非平行衬底的取向, raman谱随偏振条件的不同而变化。
The main advantage is depressing the explosive quantity and minishing the destroying to the construction foundation . meanwhile , which can improve the blasting effect , made the rock fragment more uniformly , and improve the blasting efficiency 它的主要优点是可降低炸药单耗,减小对建基面的破坏;改善爆破质量,使破碎块度更加均匀,从而提高爆破效率。
E ) with the help of pecvd , we found that high substrate temperature is advantage to the basal plane orientation . higher temperature helps the particles absorbed on the substrate moved to the location of two - dimension nucleation rapidly E )高温有利于基面平行于衬底的取向,在高的生长温度下吸附于衬底表面的沉积粒子能够迅速迁移到二维核的位置,并使粒子有足够能量调整位置。
The paper introduces the application of following new technologies in letan hydropower station construction and their effects : distributed optical fiber temperature test technology , cement paste grouting watertight technology , horizontal presplit blasting technology of foundation base 摘要介绍分布式光纤温度监测技术、水泥膏浆堵漏防渗技术和建基面水平预裂爆破技术在乐滩水电站工程施工的应用及其效果。
When combined method is applied , damaged area develops from down stream to up - stream , besides , controlling effect of discontinuous joints is shown . at normal storage water level , the combined safety factors are 4 . 05 and 3 . 75 for 9b and 4b respectively 结果表明,超载法时,破坏区从上游向下游发展,且破坏前锋一直沿建基面附近;综合法时,破坏区从下游向上游发展,并表现出裂隙结构面参数的控制作用。
At present , a datum plane - conversion scheme is introduced in the sight system of active ground - to - ground missile . in this scheme the datum plane of sight system is transferred from inertia combination to missile terminal , and the angle of two datum planes is measured at the technical position 目前,常规导弹在瞄准中采用了基面转换方案,将导弹瞄准基面由惯性组合转换到弹体尾段,两基面夹角在技术阵地测量。
But repetitious launching tests show that there is a remarkable error in the measurement of the angle which is measured in the technical position . the error has so notable effect on sight precision of weapons that this scheme is abandoned in the design of later missile weapons 但经多次发射试验证明,技术阵地测量的两基面夹角存在较大误差,对武器的瞄准精度产生了较大影响,以致后继的某些型号放弃了基面转换方案。
The sliding resistance mechanism of deformable earth bodies by means of well point drainage lies in lowering the underground water level to reduce the water content of the earth bodies and raise the shear strength , improve the stability of the deformable earth bodies and increase their sliding resistance 摘要井点降水常用于地下水位高出开挖建基面许多或含水丰富的土体基坑工程中,井点降水在土质变形体中的抗滑作用机理在于,通过井点降水,降低地下水位,使土体的含水量减少,提高其抗剪强度及变形体的稳定性,增加其抗滑力。
