Two different section planes'y coordinates are used to obtain one length size of human and a method, called convex hull method, to measure body section's girth, respectively. Using this technique, the 34 key figure lengths and girth sizes can be measured, and the factors affecting measurement precision can be analyzed.

From the point of view of structure,bamboo cell wall ratio,amount of bundle per unit area,fraction of bundle sheath,fraction of vessel increase from the root to the top of the bamboo,while fractionof parenchyma.Single bundle sheath area decreases with the increase of height.Fiber length,fiber width and vessel length increase from the root to the top andget theirs maximum value at the length of 17th node to 23rd node and thendecrease.Fiber length and width ratio slightly decreases while vessel widthincreases with the increase of height.

从构造角度来说，竹材胞壁率、单位面积维管束个数、纤维束比量、输导组织比量从基部到到梢部随着高度增加而增加，而薄壁组织比量、单个维管束纤维束面积随着高度增加而减小；纤维长度、纤维宽度、导管长度从基部到梢部随着高度的增加而增加，在第17竹节到第23竹节达到最大值，而后下降，纤维长宽比随着高度的增加而缓慢下降，导管宽度随着高度增加而一直增加。

When an order is form in position machine, the needed breeds and quantity of cigarette will be established and thesequence and time of cigarette sorting in an order will be also established, so before sorting an order, the order'length can be compute, but before sorting an order, the order's space is existenced as a virtual space, thus supposed a virtual space which loaded finished cigarette and order when virtual space arrive the corresponding sorter, plc control the time parameter and activated the sorting, and the sorter sorting cigarette to virtual space, an order accomplished.

对件烟行走时间进行了建模并提出了一种烟草自动分拣算法，当订单在上位机生成后，所需烟品种及数量随之确定，因此订单中所要分拣的烟分拣的次序及分拣的时刻也就可以确定，所以在订单分拣之前，订单的长度是可以计算出来的，而在未真正分拣之前，订单的长度是一个&虚拟存在的空间&，应用逆向推理的过程可假设一个装成品烟和订单的&虚拟空间&，当&虚拟空间&到达对应的分拣机位置时，通过plc对订单中件烟时间参数的控制，分拣机自动分拣件烟至&虚拟空间&完成订单分拣，该算法实现方便并能节约大量的硬件成本，对其他一些物流分拣行业也具有一定的推广价值。
