The structure of the compound Sm6Al3Si was refined from X-ray powder diffraction data (Tb6Al3Si structure type, space group I4/mcm, a = 11.733(1), c = 15.266(2) Å, Z = 8, RB = 0.0569).
In the ternary systems Sm-Al-Si and Gd-Al-Si, the R6Al3Si phase with a Tb6Al3Si-type structure was also identified [10].
The studied alloy contained, in addition to the compound Sm6Al3Si with a Tb6Al3Si-type structure, significant amounts of secondary phases, which were identified as SmAl [11] and Sm3Al [12], crystallizing with a DyAl- and Cu3Au-type structure, respectively.
Discussion The structure of Sm6Al3Si [14] is a substitutional variant of the Gd3Ga2 type [15].

Introduction In recent years, with the rapid development of modern industry, the corrosion of building structures has become an increasingly serious disaster, therefore the corrosion research on the concrete materials has caused extensive concern of the experts at home and abroad.
This paper, on the basis of the research on the physical chemistry properties of the mortar specimen, analyzes the physical chemistry and mechanical properties shown in the different corrosion periods, and discusses the corrosion process and mechanism of concrete materials, puts forward the generalized model of the sample porosity changes considered corrosion process, and deduces the formula of flexural strength changed with time, and has the preliminary validation.
Take a differential element of per thickness from the mortar specimen, assuming that accumulated pores produced by chemistry reaction can be deduced from the cycloid equation by rotating, as is shown in figure 2, the length, width and thickness of the differential element are all b, and the radius of the circle is a.

It was found that pore structure of CCACs prepared was beneficial for benzene adsorption, but preparation variable in the process has little effect on the surface chemistry of CCACs prepared.
The surface functional groups and structure were studied by Fourier transform infrared spectroscopy (Nicolet 380 FT-IR).
The surface chemistry of raw coal, unwashed semicoke, washed semicoke and obtained CCACs was evaluated by FTIR, as can be seen in Fig. 1.
Compared curve 1 and 5, it was found that both spectra had similar absorption bands, being the only difference in their intensities and a slightly shift in wavenumbers, which indicated just small differences in the surface chemistry between raw coal and obtained CCACs, and preparation variable in the process had little effect on the surface chemistry of CCACs prepared.

Index QT can not only efficiently distinguish molecular structures of mercaptans, but also possess good applications of QSPR/QSAR (quantitative structure-property/activity relationships).
And the QSPR/QSAR models constructed by these topological indices have been widely used in many fields such as organic chemistry, medicinal chemistry, environmental chemistry, spectroscopies, etc [12~19].
Invariants derived from the graph can be used to characterize chemical structure.
