滚草

The theoretical analysis and optimizing design were implemented to the structuralparameters of major working components, such as the clearance between cutter heads, thearrange of bent blade, grass removing angle and setting angle.

本文通过上述的试验和分析，给出了刀盘间距、机器前进速度以及刀滚旋转速度这三个因素在满足作业要求(覆盖率、埋草深度、碎土率)的前提下，降低功耗的最优组合方案，为进一步进行整机参数优化设计提供了重要的理论依据。

What Is Tumbleweed?

什么是风滚草？

The tumbleweed said "Oof!" in the surprised way they always did when something caught them, and went in through the opening.

像它的同类被抓住时一样，这只可怜风滚草照例'噢'得惊叫了一声，接着就被拖到了里面。

Such robotic behaviour is useful when you are barrelling down a wide dirt track with the occasional tumbleweed—but not when encountering a stop sign or oncoming traffic.

当你在宽阔的泥道上——偶尔有一些风滚草之类的植物——快行时，这种自动化功能很有用，但一旦遇到停车标识或是驶来的交通车辆时就不管用了。

The town's same is reported to have several possibly origins including the old Ute Indian word for tumbleweed, the name of an Native American chief or "tu-wanda", the Goshute word for "bear."

They sit this winter like beached green whales on the frozen plains outside Wichita, Kans., two years overdue,$385 million over budget and gathering controversy like tumbleweed.

今年冬天，这两架飞机就像两头搁浅的绿鲸那样栖息在堪萨斯州威奇塔城外冰封的原野上。交货过期了两年，超过预算达三亿八千五百万美元，招来的非议象风滚草般日益增多。

Its tip flicked twice around the tumbleweed, jerked it off the ground and back to the feed opening in the imitation tree stump within which the rest of the slurp was concealed.

舌尖绕着风滚草圈了两圈，然后猛得将其拉起来，往模仿树残桩里的进食口拖去，啜食者正是隐藏了里面。

Some are more like sunflowers and tumbleweeds and just roll with the punches, fit in and are easier. Others are more temperamental, need more nurturing, and are simply more difficult to raise like African Violets or orchids.

一些更像是太阳花和滚草，比较柔顺，另一些个性更加倔强，需要更多的营养物，并且像非洲的紫罗兰或兰花那样更难养育。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
