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。

In the one half part, according to the strontium nature, thermodynamic calculation of correlative reaction and the principle of the vacuum aluminothermy reduction process, with the laboratory findings of preparation strontium by vacuum aluminothermy reduction compared and analyzed in different parameter conditions, a variety of factors which effect the decomposition rate of SrCO_3 and the percent reduction of strontia are gotten out. The factors include that the decomposition rate of SrCO_3 is influenced by different addition and pressure. They also include that the percent reduction of strontia is influenced by excess coefficient of reducing agent aluminium powder, the particle size of raw material or reducing agent, the pressure of barbecuing, temperature and reduction time. According to those, we can draw the conclusion as follows:(1) Decomposition temperature of SrCO_3 is decreased by adding carbon and alumina in different degree.(2) With quantitative carbon added under the vacuum condition, the decomposition temperature of SrCO_3 is decreased obviously, which can fall 150℃ compared with atmospheric pressure.(3) In keeping 1150℃ of 2.5h, under the 5Pa vacuum condition, the decomposition rate of SrCO_3 nearly keeps in 99% steadily.

在前半部分的真空铝热还原法中,根据锶的性质、相关反应的热力学计算及真空铝热还原法原理,通过对不同参数条件下的真空铝热还原法生产金属锶的实验结果的分析比较,得出了影响SrCO_3的分解率和氧化锶的还原率的种种因素,具体因素包括不同添加剂、不同气压对SrCO_3分解率的影响,还原剂铝粉的过量系数、原料与还原剂的粒度、制团压力、温度和还原时间等对氧化锶还原率的影响,得出具体结论如下:(1)添加碳和Al_2O_3能不同程度的降低SrCO_3的分解温度;(2)真空条件下加入一定量的碳可显著降低SrCO_3的分解温度,比之常压下可降低150℃之多;(3)在1150℃恒温2.5h、真空度达到5Pa的条件下,SrCO_3的分解率几乎保持稳定在99%;(4)氧化锶的还原率随还原剂过量系数的增大增大,但是趋势越来越小,当过量系数超过25%后,氧化锶的还原率几乎不再增加;(5)氧化锶的还原率随原料与还原剂的粒度的变细而增加;(6)氧化锶的还原率随制团压力的增加而增加,但超过一定值后,氧化锶的还原率反而会下降;(7)氧化锶的还原率随还原温度的升高而增加;(8)氧化锶的还原率随还原时间延长而增加,在本实验条件下,超过2.5h趋于稳定。
