割

I want to look at the mowers, and wonder why fatness, elderliness, and black trousers should inevitably wear a new straw hat of the boater variety, move in stiff jerks, shove the end of the scythe-strokes with a certain violence, and win my hearty disapproval, as contrasted with young long thinness, bright blue cotton trousers, a bare black head, and a pretty lifting movement at the end of the scythe-stroke.

我想看割草人，想知道为什么这个胖子、长者和黑裤子竟非要戴一顶硬边的新草帽，而且动作不灵活，颇废气力地用长镰的刀尖割草；而年轻人又高又瘦，身着天蓝色棉布裤子，一头黑发，不戴草帽，用长镰割草时，刀尖优美地向上一提，使我在对照之下对年长者产生由衷的不赞同。

He said:"The old varieties of seaweed can only cut up to 8 knives, and cutting to the final quality of the more worse, bad side, while 'space on the 1st red' is not the case, it generally 10-12 knife to cut, color black Liang,taste, high production value."

他说："老品种紫菜最多一般只能割8刀，而且越割到最后质量越差，烂边多，而'太空红1号'就不一样，它一般能够割10-12刀，色泽黑亮，口感鲜甜，产值也高。"

The result showed that the volume, dry weight and total sugar content of root gradually reduced with the harvest frequency, but the reductive sugar content in root increased. While the harvesting frequency was two times per year, the volume and dry weight of alfalfa root showed an decreasing at beginning and then increasing when the first harvesting was at different growth stages and the lowest values were at flowering period however, it was not significant for brome.

结果表明：随刈割次数增加，两种牧草根体积、根干重和根部总含糖量逐渐减小，而根系还原糖含量呈逐渐增加的趋势；在年刈割两次，首次刈割分别在不同生育时期试验处理中，苜蓿根体积和干重呈先减后增趋势，首次刈割在盛花期根体积和干物质含量均最低，而无芒雀麦变化不明显。

The growth of unmowed part of a clone did not affected by removing ways in ramet level. But the leave number per tiller was higher in treatments 2, 3, 4 and 7 at 2 months after cutting in tiller level.

在分株层次上，不论刈割方式如何都没有影响无性系未刈割部分构件的生长发育；在分蘖层次上，去除量较少的处理（2，3，4，7）中未刈割部分每分蘖叶数至刈割后2个月时增加较为显著。

A factorial field experiment was conducted with seventy-eight 1.3×0.8m plots subjected to 24 treatment combinations (2 fertilization×2 first clipping time×3 clipping frequency×2 clipping intensity), with one unclipping control treatment.

实验采用随机设计，肥力分为施肥和不施肥，刈割处理为刈割时间、刈割频度和刈割强度3因子组合。

But, undercut technology may deteriorate the stresss concentration. In order to improve the situation, for a crank throw of a given ductile iron crankshaft, finite element analysis is conducted. The analysis result is optimized and related fatigue calculation is carried out. A compare between calculation and test results is performed and compared results show that conculation result is reliable. Therefore a good undercut structure is found and the reliability of crankshaft is improved.

球铁曲轴加沉割槽往往会加大曲轴的应力集中，根据某厂设计的球铁曲轴，本论文利用有限元分析的方法，对其单拐曲轴的沉割槽进行有限元模拟分析，在分析结果的基础上进行优化设计，最后得出较好的沉割槽结构，从而得到较好沉割结构，提高曲轴的可靠性。

The results show that the methane drainage quantity from the bores perpendicular to face cleat was 1.2 times that of the bores parallel to face cleat in any time and the difference between them becomes more distinct with the drainage time increasing. In the research area, the bores perpendicular to the face cleat was 2.61 times that of the bores parallel to face cleat in maximum drainage quantity and 4.34 times that in drainage effect, and the reasonable time is about 300 days.

结果表明：垂直面割理方向钻孔的抽放量在任何时刻都明显高於平行面割理方向钻孔的抽放量，抽放时间越长，两方向抽放量之间差距越显著；研究区垂直面割理方向钻孔的极限抽放量是平行面割理方向钻孔的2.61倍，抽放率高出4.34倍，合理抽放时间在300d左右。

The features and the performances of the longitudinal cutting head and the transverse cutting head of the heading machine are compared in view of the problems in use.

针对掘进机纵轴式截割头和横轴式截割头在使用中各自存在的问题，使用比较的方法对掘进机纵横两种截割头的特点和性能进行了分析比较，发现两种截割头在不同的工作情况中有各自的优缺点。

Mowing suppressed seedling emergence of tall-growing Stipa krylovii by affecting seed availability due to reproductive parts removal when mown in the previous year, whilst exerted a positive effect on low-growing Cleistogenes squarrossa probably as result of increased light availability and less competitive pressure from adult individuals, because mowing largely lowered the vegetation height and density. 3."U"shaped curve for seedling mortality across the entire growing season was thought to be associated with seasonal changes of air temperature but a small peak from mid-June to early July could probably be attributed to drought due to previous rainfall shortage.

自5月下旬至8月中旬，三种禾草的实生苗密度总体上都呈上升趋势，但刈割和放牧会使克氏针茅的实生苗密度受到抑制，表明前一年的刈割去除部分生殖器官影响形成实生苗的种子来源；刈割和放牧对生长较低矮的糙隐子草实生苗会产生正向效应，对低矮和稀疏植被进行有规律的刈割会增加植物群落内部的光照，减轻实生苗与成年母株的竞争。

To adopt band type rail rolled by stainless steel and chain type drive method run circumferential movement along with the pipe to be cut by flame cutting carriage,cutting torch will run radial movement driven by ball bearing screw by step motor along with the pipe to be cut,the above two dimension movement compose to inclined cutting movement of cutting torch,the inspection of circumference position of cutting torch,the determination of radial position and return point of cutting torch all controlled by SCM.

为了满足钢管斜截切割的要求，建立了钢管斜截切割的数学表达式，采用不锈钢轧制的带形轨道和链式传动的方式使火焰切割小车沿被切钢管做周向运动，割炬沿被切钢管的轴向运动由步进电动机带动滚珠丝杠完成，上述两维运动合成为割炬的斜切运动，割炬周向位置的检测、割炬轴向位置及折返点的确定均由单片机控制完成。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
