回旋螺线

For the technically curious, we use a close approximation to a 'clothoid' spiral, which makes for a smooth ride while still being computationally inexpensive.

从技术角度讲，我们采用了接近于"回旋螺线"的设计在保证流畅驾驶的同时不增加运算量。

Then, the design and calculation of high voltage platform, central region, spiral inflector and the axial injection beam line is described in detail. The result of research shows that axial injection with high voltage platform is not only feasible but also efficient.

论文首先描述了与设计相关的回旋加速器理论，束流传输理论和空间电荷效应的有关理论，然后对组成该系统的高压平台，新的SFC的中心区，螺线静电偏转器和轴向注入束流线的设计研究作了比较详细的描述。

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。
