撞击装置

Based on the 10060 Λ hyperons candidates events selected by us in 27. 6GeV longitudinal polarized e〓 deep inelastic scattering on unpolarized fixed proton target at HERMES, the spin transfer from fragmented u-quark to Λ hyperons, S〓, is measured.

本论文利用HERMES实验装置上的27.6GeV纵向极化正电子束与固定不极化质子靶的深度非弹散射的实验原始数据，重建了10060个Λ超子候选事例，对该过程中核子内被撞击的u夸克在碎裂过程中转移到Λ超子的自旋S〓进行了分析。

But further safety measures, including head gear that would lessen the impact of any knock to the head, might be warranted, he said.

但将来可能会出现一些保护装置，比如可以用来减轻撞击对头部影响的头部装备，他说。

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。
