A multi-distance measurements method is employed in this paper. A single parameter fitting method and a double parameters (reduced scattering coefficient and amplitude factor) fitting method on the basis of the least square Newton fitting algorithm is used to derive the optical parameters respectively. For the finite-thickness homogenous tissue, it can be concluded that the rest terms in expressions of diffusion reflectance and transmittance for the corresponding tissue geometries that subtract the exponential term contained source-detector distance depend on the detected position weakly.

在多程测量的基础上，使用单参数最小二乘牛顿法拟合方法和双参数（约化散射系数、幅度因子）最小二乘牛顿法拟合方法，得到有限厚均匀组织的反射率分布和透射率分布公式中除去包含测量位置的指数项的其它部分对测量位置皆具有弱依赖性的结论，并对拟合结果进行了分析讨论；而对于有限厚平板状双层组织，可根据对反射测量结果及透射测量结果进行拟合所得的约化散射系数间的差异及常数因子的正负判断双层组织的可能结构分布。

This test uses the "method of fire resistance test for structural parts of building" of Chinese national standard CNS12514 A 3305 as the criterion and small heating furnaces to complete the following three kinds of tests:(1) different material ingredients of single layer fire curtain ,(2) different hollow layer spacing of double layer fire curtain, and (3) installation of natural smoke vent of double layer fire curtain, with a view to acquiring basic data of insulation performance and determining if it meets the requirements stipulated by related specifications.

本试验将以中国国家标准CNS12514 A3305「建筑物构造部份之耐火试验法」作标准，并利用小型加热炉完成(1)单层截火幕不同材质成份、(2)双层截火幕不同中空层间距、(3)双层截火幕设置自然排烟口之三种试验类型，以期获得阻热性能之基础资料与是否符合相关规范之要求。

In order to determine the bacterial composition of the community,11 isolate strains were detected by plate isolation,while a community reset by the 11 isolate strains lost the capacity of degrading cellulose. The capacity of degrading of the filter paper in double deck plate and monolayer plate were determined,only the filter paper in double deck plate were degraded,that means the main or key microbe are anaerobic.

为系统了解复合系的菌种组成，在有氧条件下，利用传统的平板画线法分离到11株单菌，将11株单菌按体积比1∶1重新组合并不具备分解纤维素的能力，利用单层和双层平板滤纸法检测NSC-7的分解能力，发现只有双层平板上的滤纸变黄且降解，说明复合系内纤维素降解的关键菌是厌氧或微好氧菌。
