极光

We study the substorm dipolarization occurring from 1730 to 1930 UT on Sep. 14, 2004 based on DSP/TC1, Cluster and Polar data, combined with the aurora and geosynchronous energetic particle measurements and ground-based magnetic field observations.

利用TC1、Cluster和Polar结合极光和同步高度及地磁的观测，研究了2004年9月14日1730~1930 UT时间段的亚暴偶极化过程。

It has also been alleged that the HAARP, or "High Altitude Active Auroral Research Project", which can use the ionosphere as a giant antenna for broadcasting signals, may be used to entrain various mind/body states in large areas of the planet.

也有人指称haarp ，或"高频率活跃极光研究计划"，可利用电离层作为一个广播信号巨型天线，可用于在地球的大范围诱导大脑/身体状态。

Aurora is going to fade into the sky of dawn with a bright melody of silence.

极光也在舒畅旋律的改变中在黎明天空里慢慢的消逝。

极圈里的挪威小镇，我有生以来第一次见到极光和峡湾的地方

"Sucrose (C12H22O11) is a disaccharide; hydrolysis, by the enzyme invertase, yield s "invert sugar"(so called because the hydrolysis results in an inversion of the rotation of plane polarized light), a 50:50 mixture of fructose and glucose, its two constituent monosaccharides."

蔗糖(C12H22O11)是双醣；由转化水解后产生转化糖(名称是因为水解产物会将偏极光的平面反转)，果糖和葡萄糖各半，这是两种单醣成份。

In the present paper, we analyze the characteristics of aurora, ionospheric current system and the AE index.

本文对1998年8月6日系列亚暴事件的极光活动、电流体系和AE指数的形态特征进行了分析。

Aurora only uses lock washer or embroidered eyes and nose for safety.

极光只使用垫圈或绣眼睛和鼻子的安全。

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。
