As the track space increasing, the holding power which flexible holding parts act on sugarcane is dropping off. As the canvas layers and length of flexible holding part increasing, the track space is also increased when flexible holding parts act on sugarcane same holding power. As the length of flexible holding part increasing, the rate of slope of holding power following the track space to change would be decreased, so holding power would vary slowly. The holding power has a better linear relationship with the track space. Holding sugarcane stalk on knot or not on knot, sugarcane stalk having leaves or without leaves, the holding power would have not significant difference. Considering the structure of device and stress of sugarcane, 4-layers canvas conveyer belt was used as flexible holding part, while its length is 120mm, 160mm, or 200mm, the corresponding maximum track space is 135mm, 183mm, or 235mm. Experimental investigation of sugarcane windrowing was done on the arc-track-type flexible holding and conveying test mechanism.

随着轨道间距的增大，柔性夹持元件施加给甘蔗的夹持力逐渐减少；施加给甘蔗相同的夹持力，随着柔性夹持元件帆布帘层数和长度的增加，对应的轨道间距增加；随着柔性夹持元件长度的增大，柔性夹持元件施加给甘蔗的夹持力随轨道间距变化的斜率减小，夹持力大小的变化越缓慢；柔性夹持元件提供的夹持力与轨道间距均呈线性关系；柔性夹持元件夹在甘蔗节上还是不夹在节上，甘蔗有叶还是无叶，其施加给甘蔗的夹持力无显著差异；从夹持输送装置结构以及甘蔗的受力情况来考虑，选择4层帆布帘输送带作为柔性夹持元件更能平稳、柔和地夹持输送甘蔗，4层帆布帘120mm、160mm、200mm长的柔性夹持元件夹持甘蔗所需最大轨道间距为135mm 、183mm、235mm。

The peak dropped instantly, a great belly of loose canvas floated broad upon the water; and since, pull as I liked, I could not budge the downhaul; that was the extent of what I could accomplish.

桁端的帆角立即落下，松弛的帆挺着大肚子漂浮在水面上。我无论如何用力也拉不动帆索，我也只能做到这个程度了。

I had the biggest Maggazin of all Kinds now that ever were laid up, I believe, for one Man, but I was not satisfy'd still; for while the Ship sat upright in that Posture, I thought I ought to get every Thing out of her that I could; so every Day at low Water I went on Board, and brought away some Thing or other: But particularly the third Time I went, I brought away as much of the Rigging as I could, as also all the small Ropes and Rope-twine I could get, with a Piece of spare Canvass, which was to mend the Sails upon Occasion, the Barrel of wet Gun-powder: In a Word, I brought away all the Sails first and last, only that I was fain to cut them in Pieces, and bring as much at a Time as I could; for they were no more useful to be Sails, but as meer Canvass only.

我相信，我现在所拥有的各种武器弹药，其数量对单独一个人来说是空前的。但我并不以此为满足，我想趁那只船还搁浅在那儿时，尽可能把可以搬动的东西弄下来。因此，我每天趁退潮时上船，每次都运回些东西。特别是第三次，我把船上所有的粗细绳子通通取了来，同时又拿了一块备用帆布，那是备着补帆用的；我甚至把那桶受了潮的火药也运了回来，一句话，我把船上的帆都拿了下来，不过我都把它们裁成一块块的，每次能拿多少就拿多少，因为现在，我需要的不是帆，而是帆布。

Based on the conclusions of passive control and stable conditions of the coupled system, the passive stability configurations of solar sail on displaced solar orbit and at artificial Lagrange point are designed.

被动控制要求太阳帆的法线方向与太阳光之间的夹角保持不变，此时太阳帆的轨道总是稳定的且其轨道参数由太阳帆的初始角动量唯一确定。
