This standard is applicable to 1 series, the replacement of base metal, the special support, the process of environmental protection and the inspection method with low resistance. 1 also the same cutting quantity and breaking
1.1 the same with the joint standard benefit teaching to produce the tactical phenomenon in the purchase conditions, :.2 test standard joint cold hot way joint, need to use heat, test must leave the material shadow use area research deformation area, 1. the same should 21 ~, after
1.4 the sample surface this fat consumption no fast change plan according to, no library two pollution etc., 2 fast the same strong
2.1 to use the following than the automobile to reach the image gallery, the relative platform is allowed to use the energy should be doubled industry knowledge lack of government dangerous reagents, sequence

Fill the energy drop in the batch, heat to 40-creation, the education questions are all complete, then the environment resources are all, please have a good price, after the benefit, add
all long bases, the base contains gold
GHu compound
2.2, the sample is diffused and etched under the most precious state, the sample can be passed through the reagent industry or the month has been stationed in the reagent, the agent can be used to simulate the method, but the common ingredients must ensure that the annular station can be used. 2.3 The night time guarantee is low and fast, and the time can be generally 5~30m, because this time the amount of money back to the new house state hall
2.4 The single increase of the mountain, do not ask the surface of the fast product to flow down the net, if necessary, can use 5% of the sulfuric acid % of its liquid death. When the free use of the No. 2 diffuser in Table 1, the monthly energy can be relatively 1m, this 19m], before the weight of 5Ug of the concentration of the flow after the explosion with a fast fan to dry or absorb water to think ten, with the evaluation of the pet
