The analysis show that O-forming is accomplished by bending of subdividing suspend arc,characterized by evolvement of curvature peaks form one to multiple peaks,which have nearly equal peak-to-peak distance.Process loading has corresponding episodic changes,and each episodic curve is similar.Loa...

载荷在成形过程产生相应的阶段性变化，各段位移载荷曲线具有相似性，并且载荷随悬弧的细分明显增加。O成形过程分为4个阶段：U形口合扰、直边弯曲、悬弧二次弯曲和悬弧多次弯曲过程。

Numerical analysis indicated that B2817 was a species of genus Vibrio and shared a high homology with V. gazogenes. However, there were obvious differences between them in phenotypic and chemotaxonomic characterization. The result from this study indicates that B2817 is probably a novel species of Vibrio.

经多相分类学鉴定，发现B2817是弧菌属中一个种，与弧菌属中的产气弧菌Vibrio gazogenes亲缘关系最近，但两者在形态、生理生化特征、分子遗传等方面存在很大差异，故认为B2817可能是弧菌属的一株未被认识的新种。

Toptie Welds already designed and produced the narrow gap welding machine, mechanical saddle joint welding machine, numerical controlled saddle joint welding machine, saddle hole cutting machine and strip overlaying subarc welding machine and so on. Those had already applied in some famous pressure vessel and boiler producer successfully and gained consistent appraise.

公司目前已有深坡口窄间隙埋弧焊机、机械马鞍形埋弧焊机系列、数控马鞍形埋弧焊机系列、马鞍形管孔切割机、埋弧带极堆焊等系列产品，并已在国内外著名压力容器、锅炉企业成功投入使用，获得客户的一致好评。

There were many heterobacteria aid vibrios but few Vibrio parahaemolyticus in living bait. The correlation coefficients between larvae and heterobacteria and vibrios in water were 0.704 and 0.840 in culture system respectively, while the correlation among heterobacteria, vibrios in living bait and larvae, oater were weak or negative.

活饵中异养菌和弧菌数量很大，致病性副溶血弧菌量很低养殖体系中幼体与水体中的异养菌和弧菌的相关系数分别为0.704和0.840；活饵中异养菌、弧菌与对虾幼体和养殖水体相关性很低或呈负相关。

Therefore, adding gassing material can improve the post current zero dielectric recovery strength.

说明在弧后金属栅片灭弧室能够承受较高的恢复电压，熄弧性能优于多纵缝陶土灭弧室。

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。
