Piv measures vector fields of continuous phase ( current field ) by measuring tracking particle which traces current field . ptv measures disperse phase ( bubble ) velocity , this technique realizes simultaneity measurement of two phases Piv算法通过示踪粒子测量连续相(水流流场)的矢量场, ptv算法对分散相(气相)进行量测,实现了两相的同时测量。
The sem results showed that baso4 particles in tpu had a trend to form a continuous phase , which appeared a typical concrete structure ; and with the increase of content of baso4 the above structure became more evident 从sem照片可以看出, baso _ 4在聚合物中有形成连续相的趋势,出现了典型的“混凝土结构” ,并且随baso _ 4加入量增大,这种结构就越明显。
Under considering the impact of bubbles on the turbulence , the k - ? model modified with the presence of microbubbles is employed , postulating the turbulent kinetic energy k and the dissipation rate ? are the properties of continuous phase 考虑到气泡对湍流的作用,本文采用了经过气泡修正的k -湍流模型,并假定湍动能k及其耗散率是连续相的属性。
A new type of structure of the solid - stale displacement reactions which named spiral - mtergrowth - aggregate structure was discovered in the mo2c - si diffusion couple and was considered as the result of spinodal - decomposition continuous phase - transformation 昆明理工大学博士学位论文2002 . 5摘要6 .初步发现了一种新的固态置换反应形貌结构:螺旋共生束集型结构。
We find it has the same behavior as that of the continuous phase transition in bcs super - conduction theory : the nonzero ground state energy gap decreases to zero at the finite critical temperature tsp , and the specific heat takes on divergence 我们发现该相变同bcs理论的连续相变极为相似:基态非零的能隙在有限的临界温度t _ ( sp )处降低为零,而比热呈现出趋于无穷的发散。
