Introduction There has been increasing interest in the use of slow positron beams in various fields of science.
To obtain intense beams accelerator-based positron sources[1,2,3] and reactor-based ones[4] have been developed and used successfully in studies of various materials.
An example of the Ps-TOF spectrum of a low-k material is presented in Fig. 3 where the vertical axis represents pulse height and the horizontal axis represents time.
Acknowledgement We express our thanks to Professor Uedono of University of Tsukuba for letting us use his specimen of low-k material.

These cycles impose mechanical stress on battery materials through repetitive expansion and contraction, especially in active electrode materials and the casing.
Using heat pipes or phase change materials (PCMs) for active thermal management systems minimizes these problems [41, 42].
Thus, adding intrinsic thermal and corrosion-resistant materials is critical for long-lasting and efficient battery functionality.

Since the material is stainless steel, at the front of the weld pool ,the violent electric arc will produce strong catoptric light, which may affect the feature extraction of the pool front-end.But it will not affect the feature extraction in this experiment.

Fig.1 Structure of grouted anchor (M22 type anchor) Grouting Material.
Common grouting materials include cement grout, three ethanol ammonia grout, sodium silicate single grout, sodium silicate double grout, hydrogenous quick-setting material and chemical grout.
So usually those two materials are not suitable for the project.
