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 use of footscan balance test system of national high-level pistol, rifle shooters had a balance of stability tests, by analyzing the following major conclusions: First, all the athletes in men's pistol shooting athletes body posture and adjusting the balance of stability the capacity of the worst; the second, firing only state body sway eyes open area and before and after the shaking smaller decrease; and thirdly, the general balance of the stability of indicators (both before and after the body center of gravity, around shaking rate, trajectory length, shaking the area) can not accurately reflect the high level of shooting athletes balance the characteristics of stability, and derived indicators - per unit area of the track length (the total length of track and shaking the area ratio), both show the balance of stability, but also reflect the attitude adjustment ability, in the sway area certain circumstances, the greater its value, indicating that ability to regulate the more intense the frequency of shaking sooner, the better the stability of physical balance, in the actual shooting of firearms at the time of the impact of the smaller, can be used as shooting athletes evaluation and selection of indicators.

运用footscan balance测试系统对国家高水平手枪、步枪射击运动员进行了平衡稳定性的测试，通过分析得出以下主要结论：第一，所有射击运动员中男子手枪运动员身体姿态的平衡稳定性及调节能力最差；第二，射击训练只能使睁眼状态下身体晃动面积和前后晃动幅度减小；第三，一般平衡稳定性指标(身体重心前后、左右晃动幅度、轨迹长度、晃动面积)不能准确地反映高水平射击运动员平衡稳定性的特点，而派生指标——单位面积的轨迹长度(轨迹总长度与晃动面积的比值)，既显示平衡稳定性，又能体现姿态调节能力，在晃动面积一定的情况下，其值越大，表明调节能力越强，晃动的频率越快，身体平衡稳定性越好，在实射时对枪支的影响越小，可作为射击运动员的评价和选材指标。

PS version of sectional shape is usually the rectangle, when its bending package 5.1 after, rectangles into throughtype, which corresponds to the front panel, which is the same angle, but due to the printing plate has a thickness, resulting in a printed version of the length of the front, a printing plate on the back of a positive length is greater than the length of a description block facing some of the, a phenomenon known as the break-up of metal.

PS版的截面众少轮廓凡是为矩形，当不兵其笔直包在滚筒上后，其截面由矩形酿成扇形，此时印版的背后和版面差答着不异的包角，但因印版具有必定的厚量，导致印版背后和背后的不幼量爆发保留，印版背后的不幼量不小于背后不幼量，表明印版背后有了必定的伸不幼，这种本体称为金属的倾圯。
