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。

Basing on the Graf′s addition theorem, two expessions, interior and exterior expression, are deduced and the suitable problems for them are discussed. It has been found that the interior expression is the main point for sovling the scattering problem of circular inclusion in half-space. It also has been found that the exterior expression is the key for the scattering problem of circular arc canyon and circular arc alluvial valley, and is one of the main points for scattering problem of circular arc hill as well.

从Graf原有加法公式出发，本文给出了其内域型和外域型两种表达形式并讨论了这两种表达的适用范围，同时指出：内域型表达是求解半空间内含夹塞区出平面散射问题的要点，而外域型表达是解决任意圆弧型凹陷地形和任意圆弧型沉积盆地出平面散射问题中求解难点的关键，同时也是克服任意圆弧型凸起地形出平面散射问题求解困难的要点之一。
