Finally,we discuss the mixing and decays of multi-resonances via studying the properties of the pseudoscalar and scalar mesons.For the pseudoscalar mesons, we find the eta(1410) is mainly a glueball state by studying the decays of the ground pseudoscalar mesons. For the scalar mesons, we suggest the ground mesons contain neglect

Indoor air sources of formaldehyde are mainly in the following aspects : 1, the plywood used for interior decoration, Ximugongban, medium density fibreboard and shaving board, and other artificial plate because formaldehyde has strong sexual bond, has strengthened plate and the hardness control, corrosion functions, Therefore, the current production of imitation board use Jiaonianji merits to formaldehyde as the main ingredients thiourea aldehyde resins, plate, residual and did not participate in the response formaldehyde will gradually release of the surrounding environment is a indoor air formaldehyde main ;2, using imitation board manufacturing furniture, some manufacturers in the pursuit of profit, the use of unqualified plate. In preliminary front face material reuse inferior glue, the manufacturing processes are not standardized, as a result of customers buying home, to buy a small emission points ;3, containing formaldehyde content and may distribute to the outside other categories decorative materials, such as stickers Qiangbu, with wallpapers, chemical fiber carpet, foam, paint and paint, etc.;4, combustion, emit formaldehyde certain materials, such as cigarettes and some organic materials.
室内空气中的甲醛来源主要有以下几个方面:1、用作室内装饰的胶合板、细木工板、中密度纤维板和刨花板等人造板材,因为甲醛具有较强的粘合性,还具有加强板材的硬度及防虫、防腐的功能,所以目前生产人造板使用的胶粘剂是非曲直以甲醛为主要成分的脲醛树脂,板材中残留的和未参与反应的甲醛会逐渐向周围环境释放,是形成室内空气中甲醛的主体;2、用人造板制造的家具,一些厂家为了追求利润,使用不合格的板材,在粘接贴面材料时再使用劣质胶水,制造工艺不规范,结果顾客买回家去,等于买回了一个小型废气排放站;3、含有甲醛成分并有可能向外界散发的其他各类装饰材料,比如贴墙布,贴墙纸,化纤地毯、泡沫塑料、油漆和涂料等;4、燃烧后会散发甲醛的某些材料,比如香烟及一些有机材料。
