The joint body of the invention is the first to be combined with 1 material and Si-O, and the atomic structure is random strain, and the skeleton combined with Si-O is the first to be penetrated.
The second base material disposed in the second base material is composed of a second bonding film similar to the first bonding film. 1 and the second pierced body.
In the field of at least a part of the film formed by the first binding site of the first 1 and the field of at least a part of the film formed by the second binding site of the first 1, respectively, the higher the energy source, the separation of the separated silicon skeleton can be avoided. No. 1 forwards that the leading area in front of the membrane formed by the first joint and the leading area in front of the membrane formed by the second joint are ordinary, respectively, and the first two characters played by opponents with 1 minute are similar.
Therefore, these two materials can effectively combine body parts at low temperature according to each other's accuracy, thus achieving good results.
