Hopke and Simis ( Public Understanding of Science, online 4 October 2015) find that #fracking, the most popular of five shale-related hashtags analyzed from a 2013 period, is associated with pro-shale attitudes only 13% of the time and note that the dominant voice of the activist community, coupled with a lack of engagement from industry, is unexpected. This comment offers additional perspective on the sentiment- and actor-skewed result by noting that the term “fracking” is highly political, specifically because the spelling “frack” versus “frac” is associated with activism. Furthermore, in public speech, the industry tends to deemphasize the hydraulic fracturing process in favor of the product, consistent with the findings that #natgas is a relatively pro-industry hashtag.

This paper firstly summarizes two-dimensional numerical simulation of semi-fixed abrasive tool (SFAT), then three-dimensional model of SFAT is established by PFC3D (Particle Flow Code in 3 Dimensions). In order to make the compression ratio simulation match to experimental one about SFAT, the mechanical parameters of model are adjusted. In the direct shearing simulation, the relation between the shear stress and the horizontal shear displacement under different parallel bond stiffness are obtained. By Comparative Analysis the numerical results and test experiments of the direct shearing, the three-dimensional model of SFAT is further proven rational.
