structure and properties of compositionally graded pb zrx ti1-x o3 ferroelectric thin films 3成分梯度铁电薄膜的结构及性能
xps depth measurement suggested that the films were compositionally homogeneous along the growth direction; that the interdiffusion between znsxse1-x and ito was not serious in this deposition process; and a sharp interface had developed xps深度剖析显示所制备的薄膜,其内部成分均匀,无偏析和凝聚,界面清晰而陡峭,扩散不严重。
every possible scientific discipline is ransacked for potential connections with and corroborations of theoretical postulates of how to expand the possibilities of sound itself and its theoretically limitless arrangements, compositionally speaking 搜寻每处科学的领域,为探索扩张声音的可能性,及其理论上无限可能的安排,(作曲说法);求证其理论性公理
it is shown that the proposed refinement approaches have the commonly expected properties : the behaviour of the refined process can be inferred compositionally from the behaviour of the original process and from the behaviour of the processes substituted for actions; the timed extensions of pomset partially ordered multiset trace equivalence and history preserving bisimulation equivalence are both congruences under the refinement; the syntactic and semantic refinements coincide up to the aforementioned equivalence relations with respect to a cpo-based denotational semantics 然而,对于并发系统来说,时间指标是一个至关重要的因素,很多现实生活中的并发系统都跟时间密切相关,另外,紧急事件在实时并发系统中也是常见的现象,在已研究的动作精化理论当中紧急事件都仅仅只限于用来模拟超时事件,并且是不能被精化的,这对于很多现实系统来说是一个很大的限制。
