And the long axis of simple pit Varied along with CMfs orientation of each secondary wall.This paper proposed a structure model of Phyllostachys pubescens cell wall,based on the results of CMfs deposition and thickness of each secondary wall.Secondly, it was a multilamellate structure of parenchyma cell wall,but its thin and thick lamellate was not evident.CMfs orientation on primary wall of parenchyma cell was perpendicular to cell axis.

纤维的细胞壁为典型的薄厚层相间的同心圆多层结构，初生壁CMfs排列方向与细胞轴向垂直90°次生壁中厚层的CMfs均以接近平行的小角度(0～5°沉积；薄层一般以大角度沉积，且薄层的CMfs角度由壁外侧向细胞腔里逐渐增加，直到完全垂直。

It shows that the lensless Fourier transform digital hologram can be reconstructed at any distance by Fresnel transform algorithm. For convolution algorithm,the whole reconstructed image with high resolution can be acquired in an optimal reconstruction range or a small area around it.

结果表明：利用菲涅耳变换算法对离轴无透镜傅里叶变换数字全息进行重建时，无重建距离的限制；采用卷积重建法只能在最佳再现距离附近一个非常小的范围内才能获得高分辨率再现像；而采用角谱重建法在略小于最佳再现距离及大于最佳再现距离较大范围内重建，均能获得高分辨率的再现像。

Single-axis acoustic levitation of the heaviest solid (iridium, p = 22.6g/cm3) and liquid (mercury, p = 13.6g/cm3) on the earth is achieved by greatly enhancing both the levitation force and stability through optimizing the geometric parameters of the self-developed single-axis acoustic levitator.
