This process is makes the improvement in the original two person two-sided synchronized GTAW process which one time welding two-sides formings, we have carried on a series of welding testing on 8mm SUS304, this new process has be able to decrease weld defects on the tradition two person on both sides synchronized GTAW process, shortenned construction work period, increase welding quality, as well as eliminate tradition two person on both sides synchronized GTAW for SUS304 austenite stainless steel in easy emergence of incomplete joint penetration and porosity.

此工艺是在原有的双人双面同步钨极氩弧焊工艺基础上进行的，即将原有的一次焊双面成形改为两次焊成形，经过在厚度为8 mm的SUS304上进行的一系列焊接工艺试验，验证了这项新工艺既减少了传统工艺中繁琐的工艺过程和焊接工艺缺陷，缩短了施工工期，提高了焊接质量，又消除了传统8 mm SUS304不锈钢双人双面同步钨极氩弧焊过程中易出现的未焊透和咬边现象。

A detailed CO2 laser-MIG hybrid welding experiment was carried out on the 4mm mild plates to discuss the relation of laser power, arc current, the maximum welding speed and the weld shaping , as well as the joint gap.

对此，采用4mm厚Q235钢板进行了CO2激光-MIG复合焊接研究，探讨了激光功率、电弧电流对最大焊接速度的影响及其和接头间隙对焊缝成形的影响规律。

The weld parameters and other process variables (joint mismatch, root gap, thickness of parts, and part composition) effect the pool shape (determined from temperature distribution), the absolute temperature near the pool, and the temperature distribution symmetry around the pool.

焊接参数和其他工艺变量（焊缝的错位、焊根的缝隙、零件的厚度和零件的成份）都会影响熔池形状，熔池附近的绝对温度和熔池周围温度分布的对称情况。

For flanged connections,it is recommended to use face rings weld to the pipe with lap joint back-up flanges.

为法兰连接，建议使用面临环焊缝的管圈联合后备flanges。

On the condition of laser welding lap joint composed of dissimilar materials under the same parameters, the weld width was relatively narrow when the galvanized steel for boarding up.

在相同参数下焊接异种板材搭接接头，当具有镀锌层的钢板为上板时，焊缝熔宽较窄。

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。

Do fill gaps in the "operation" could be first ribbon in the "loophole" in the region cut off, and then cut the ribbons,"weld" together,"welding" as long as the first band at the interface at both ends of alignment and It is a little overlap, and then use transparent tape to the inside of the two ribbons together interface adhesion; if afraid of sticky tape is not strong, you can use thin wire in the ribbon at the joint and under the edge of the seam on the edge of a needle (This does not affect the normal work of the ribbon, ribbon work, after all, the main use of the middle region).

在做补漏&手术&时，可以先将色带中有&漏洞&的区域剪掉，然后再将剪断的色带&焊接&起来，&焊接&时只要先把色带两端的接口对齐并稍微有一点重合，然后使用透明胶带将色带内侧的两个接口粘连在一起；要是怕胶带粘性不强的话，可以用细线在色带接头处的上边缘和下边缘各缝上一针(这样不影响色带正常工作的，毕竟色带工作时主要使用中间的区域)。

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。
