- the height of weld (Hs.w.) seam depends on the power of laser radiation (PLR) while the height of the seam shrinkage distortion (Hs.d.) becomes smaller with the growth in the weld rate from 16.6 mm/sec to 33.3 mm/sec, by means of the reduction of the surface plasma intensity which results in less concentrated electrons in plasma, its narrowing towards the beam [17].
According to the data provided by A.G.

The x-ray data are presented in the bottom image (Fig. 1b), together with the simultaneous resistance and light scattering data (Fig. 1a).
of Fig. 3 corresponds to the same data set as in Fig. 2c.
The data has been split in two graphs for clarity.
Data from anneals at 380, 500 and 545 °C are shown in Fig. 4a while those obtained at 600, 635 and 700 °C in Fig. 4b.
The RBS data were fitted using double layers with varying composition.

Data from sorption or water absorption studies can be utilized.
This data can be used to accurately determine the material's average liquid water diffusivity [4].
The data were then interpreted by the authors.
The moisture meter provided data at the highest water level due to the capillarity action.
The obtained data are given in Table 1.

Rubberized concrete is one kind of modified cement-based compound material; it has the good performance as the material of cement concrete slab on temperature stability, noise reduction performance, and wears resistance and so on.[1-4] The relationship among the size of rubberized concrete slab and the joint open will be discussed in this paper.
Material Types and Parameters of Road Slab According to the experiment data [2], the laboratory tests were conducted by adding rubbers of weight ratios of 0(Portland cement concrete) and 3.5 %( Rubberized concrete) into C35 quality concrete one sized rubbers aggregate.
