8.5.6 通风、空气调节系统的管道等，应采用不燃烧材料制作，但接触腐蚀性介质的风管和柔性接头，可采用准燃烧材料制作。

The result shows that the requirements and testing methods for flammability of building materials are similar between the United State and Canada, and they mainly are engaged in the test of combustibility and flame spread. In European Union, a new classification system for flammability of building materials was implemented in 2001, which includes two systems; one is for floor coverings and the other for all other building units. In Japan, the interior materials are classified into non-combustible, quasi noncombustible and fire-retardant materials according to Cone Calorimeter method (ISO 5660). China has established a non-combustible test, a three-class classification system for combustible wall and ceiling interior finishing materials and a two-class classification system for combustible floor coverings.

通过研究认为：美国和加拿大对建筑材料燃烧性能的要求和试验方法基本相似，他们主要针对材料的燃烧性、火焰传播进行检测；欧盟于2001年颁布了新的燃烧性分级体系，该分级体系包括专门针对铺地材料部分和针对其他所有建筑构件材料和产品部门；日本采用锥形量热计法(ISO 5660)将内装饰材料分为不燃、准不燃和阻燃材料3个等级；我国对建筑材料的试验方法包括不燃性试验方法、墙和天花板内装饰材料的三级分级体系和铺地材料两级分级体系。

Since, unlike the nous and the one, the soul can contemplate its objects only in succession , it gives rise to time, space, and matter; this quasi-reality of nature in turn contemplates, but in a dreamlike state, ultimately deteriorating into the nonconscious level of matter.

由此，跟"一"、"灵"所不相同的是，"魂魄"可以预知客观世界，只是靠着念念相续这样的办法。"魂魄"中导致了时间和空间，还有物质世界。这种"真实的假象"所建构的"客观世界"随之一一进入人们的思考领域，不过，在这如梦般的场景里，人们的这些思考不免终结于物质世界的寂灭之境。

We investigate phenomenologically effects of the flavor-dependent quarkonia annihilation on the meson-meson mixing, and find that corrections due to the flavor-dependent quarknoia annihilation can be described by the constituent quark masses in the mixing model which holds for all the meson nonet. We also study the relation between Regge trajectory and meson spectrum, and therefore concluded that the quasi-linear Regge trajectory with the requirements of additivity of intercepts and inverse slopes can describe the meson spectroscopy with good accuracy, and it also holds for the radial excited mesons except for the bbbar mesons.

我们唯象地研究了味道有关的夸克偶素湮灭效应对混合的影响，发现味道有关的夸克偶素间的湮灭引起的修正可以通过组分夸克的质量来描述，考虑这种修正的混合模型可以用于所有的介子九重态；我们也研究了Regge轨迹和介子质量间关系，发现满足截距相加及斜率倒数相加的准线性Regge轨迹可以很好地描述介子的质量，除bbbar外，线性Regge轨迹也可以很好地描述介子激发态的质量；最后，我们借助于赝标介子和标量介子，讨论多个共振态的混合及衰变。
