Result The cilium columnar epithelia or cylindric cell have be found in sputum of the tracheal, no cell mentioned above was checked in sputum collected from pharyngeal portion.

For example, the steam cylinder bolt for ultra-supercritical turbine requires not only enhanced high temperature strength and ductility, but also good corrosive and wearing resistance.

例如：用于超超临界汽轮机组的汽缸螺栓，不但要求具有足够高的高温强度和韧性，而且要求良好的抗腐蚀和耐磨性能。
