Quantitative evaluation of vague structures in the biomaterials by the diffraction method and Fourier transform

生物材料具有结构复杂性，即涨落性的特点，而涨落性很难定量估计。因此，木材，是最有价值的生物材料的利用，提供了傅立叶变换分析的细胞排列，细胞形状和细胞壁厚度的观点进行评估。虽然利用电子衍射方法对一些未来生物资源藻类的纤维素微纤丝结构进行了研究，但由于傅里叶变换图像分析（FTIA）已经建立在对木材细胞上模糊结构的精确定量水平上，因此本文仅对FTIA的发展过程进行了描述，并省略了其结果。（1）木材细胞结构的显微取样程序，（2）FFT前程序，例如用于简化和提取目标结构的映射，以及FFT后包围功率级的亮度控制，（3）实际FFT程序的说明，（4）FFT后程序，例如极坐标分析，以及（5）木材细胞的光谱分析和重建程序。在所有的过程中，各种误差进行了详细的检查，并控制在10%以下的实验条件。此外，还提出并定义了与木材组织和图像处理相关的词汇和符号，在上述条件下，对针叶材管胞的细胞排列、细胞形状和细胞壁厚度进行了定量分析，并检测出其相对于最大可证值的波动。

Biomaterials are characterized in the structure vagueness, fluctuation in other word, and the fluctuation is very difficult to be estimated quantitatively. Therefore, woods, being the most valuable in biomaterial utilizations, are offered to the Fourier transform analysis to be evaluated on the viewpoints of cell arrangements, cell shape and cell wall thickness. Although some algae as the future bio-resources are investigated on their cellulose microfibril structure using electron diffraction method, the results are omitted in the report, and only the developing process for the Fourier Transform Image Analysis (FTIA) are described there, because the FTLA has been established in the precise quantitative level for the vague structures on the wood cells.The FTLA was composed of five steps, namely, (1)microscopic sampling procedures for wood cell structures, (2)pre-FFT procedures such as mappings for simplifying and extraction of objective structure, and also brightness control for the enclosing of power level after the FFT, (3)elucidation of actual FFT procedures, (4)post-FFT procedures such as the polar coordinate analysis, and (5)analyzing of spectrum and reconstructing procedures of wood cells. In all procedures, various errors were examined in detail and the experimental conditions are controlled being under 10%. In addition, many words and symbols relating the wood tissues and image processing were proposed and defined.In the above conditions adjusted, cell arrangement, cell shapes, and cell wall thickness in softwood tracheids were analyzed quantitatively and then fluctuation from the most provable value could be detected.
