Cordata, Arundo donax, Ophiopogon bodinieri, Tamarix chinensis, Amorpha fruticosa and other water-enduring shrubs planted on the slope of levee, to form the combined effect of ecology and landscape. In this district the channel has been further curved through design, to reduce the current velocity and

D区：D区为生态护坡区，在离顺坝4～5米处的土质河堤坡上部平缓处，沿顺坝方向行植水杉到顺坝三分之一处，堤坝坡面种植鸢尾、德国鸢尾、萱草、鱼腥草、芦竹、沿阶草及柽柳、紫穗槐等一些耐水湿的灌木等护坡；同时也突出景观，使生态功能与景观效果相结合。

As a kind of good material for paper manufacturing and being environmental friendly especially for salina soil, Arundo donaxl planting has good economic, environmental and social benefits, so it is planted in large-scale in many provinces such as zhejiang, Anhui, Fujian, Sichuan, Yunnan, Guangdong, Hebei, Shanxi, Shandong, Guangxi, and the planting acreage is more than 10,000,000 acres.

由于芦竹是一种优质的造纸原料，且对盐碱滩涂土壤有良好的环保作用，具有较好的经济、生态和社会效益，在我国浙江、安徽、福建、四川、云南、广东、河北、陕西、山东、广西等省种植面积达1000万亩以上。

Phosphate use efficiency of Arundo donax Linn with iron plaque was 16.5% more than that of without,31.4% for typha latifolia .

根表有铁氧化物胶膜沉积的芦竹磷素利用有效性比无铁氧化物胶膜的植株高16.5%，香蒲高31.4%。

So this research aimed to develop a Arundo donaxl-cutting test system based on high-speed photography for cutting test research on Arundo donaxl and other tall-thicker and harder crops, with the purpose to supply valid methods and ways to the academic research on the cutter of that kind of crops.

因此本课题设计研究了一种基于高速摄像技术的芦竹收割机切割试验系统，用于针对芦竹等高、粗、硬茎秆作物进行切割试验研究，旨在为进行高、粗、硬茎秆作物的切割器的理论研究和优化设计提供有效的方法和手段。

The research results would be both theoretical and practical valuable, for providing theory support and technology guidance for the optimization design and theoretical study of the cutter for the Arundo Donaxl harvester, being important academic reference for the study of cutter for other tall-thicker crops harvester, and prompting the mechanization harvesting and industrial planting of tall-thicker crops.

本课题研究能为芦竹收割机切割器的优化设计与研究提供理论支承和技术指导，并对其它高粗茎秆作物切割器的研究具有重要的理论参考价值，对促进高粗茎秆作物的机械化收获，推动芦竹等高粗硬茎秆作物的产业化发展具有重要的现实意义。

Based on analyzing and comparing the characteristics of the present cutters, the material characteristics of Arundo Donaxl has tested and analyzed in this paper, and investigated a rotating chain-type saw-tooth cutter for stalks of tall-thick and harder crops , and developed a cutting test system including the rotating chain-type cutting tester system and transportation mechanism and the high-speed photography image collecting and processing system. Arundo Donaxl cutting test has been carried out and the cutting process of the Arundo Donaxl has been photographed on-line by the high-speed photography image collecting system.

本课题在比较分析现有切割器性能特征的基础上，试验分析了芦竹的物料特性；研究了用于高、粗、硬茎秆作物切割的回转链式锯齿形切割器；设计了包括回转链式芦竹切割器、芦竹夹持输送装置和高速摄像图像采集与处理系统的芦竹收割机切割试验系统；对芦竹进行了切割试验，并通过高速摄像图像采集系统在线记录了切割过程；运用自行设计开发的高速摄像分析及其序列图像处理软件，试验分析了影响芦竹切割质量和切割效率的因素。

Furthermore, the factors affecting cutting qualities and efficiency and The research result included: firstly, matching of the tractor"s moving velocity and the cutting velocity, the degree of tightness of the cutter chain, the height of stubble, the opening of the cutting protector and the interval between two adjoining blades, the matching of configuration parameters of blades are the main factors affecting the cutting quality and efficiency; secondly, the cutter"s dynamically cutting of the arundo donaxl includes three stages: touching, cutting-in and cutting-off; thirdly, the movement tracks of stalks of Arundo Donaxl, which are cutted off has been acquired.

试验研究得到以下结论：(1)机组前进速度与切割速度的匹配、链条的张紧度、割茬的高低、护刃器的开合度及相邻动切割刀片的间距以及刀片结构参数的匹配是影响芦竹切割质量和切割效率的主要因素；(2)切割器对芦竹的动态切割过程包括接触、切入和切断三个显著不同的阶段，各阶段存在不同的切割特征；(3)得出了切割过程中被切断作物茎秆的运动轨迹曲线。

Presently, the main harvesting of Arundo donaxl is traditional manual ways, the working conditions are bad, the harvesting efficiency is low and the cost is high. To harvest Arundo donaxl on schedule and maintaining the quality and quantity is key to ensure the bumper harvest and yield, the croppers income and the timely supply as industrial material, the mechanization harvest has been urgent for the industrialization of Arundo donaxl planting and timely harvest.

然而，目前芦竹的收割仍主要采用传统的手工方式收割，劳动环境艰苦，收割效率低且成本高，按期保质保量收割芦竹是芦竹种植场丰产丰收，实现种植场农民增收和保证其作为工业原料来源的关键。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
