查询词典 ripple weld

However,when the filler is used in TIG welding,the fluidity of molten pool is improved,and the interfacial reaction between SiC_p and Al is effectively restrained,so that the satisfied ripple weld of SiC_p/6061Al composite is achieved and joint property was improved.

结果表明：不填加焊丝时，焊缝外观成型较差；而填加焊丝后，熔池流动性增强，可以得到满意的鱼鳞纹焊缝，并有效抑制了焊缝中的SiC_p颗粒和铝的界面反应，焊缝中的缺陷减少，接头性能得到改善。

In addition, the analyses of weld surface ripple and microstructure with three current waveforms have indicated that the high frequency wave group modulated by low frequency GTA welding has the advantage of both the low frequency in which the heat input of the weld pool is easily controlled and high frequency GTA welding in which the arc is energy—concentrated and stiff.

另外，通过对高频脉冲焊、低频脉冲焊、低频调制高频方波群焊不锈钢焊缝表面形貌分析表明，低频调制高频方波群焊综合了低、高频GTA焊的特点。

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。
