In colder climates, reflective markers may be installed below ground using an elongated narrow triangle, cut into the road surface that allows the device to be installed below the road surface. Newer technology allows these to be placed above ground with snowplough-able rails that attempt to protect the reflective components from the snowplough blade.
Many studies have also shown that high compliance with post mission disposal (PMD) s is necessary to guideline control the increase in space [. 3debris][4]. At present, the PMD success rate is about 20% for payload and about s 60% for rocket bodies, with PMD countermeasures not being sufficiently widespread [5].
Now the monocrystalline silicon solar panel is widely applied, and the photoelectric conversion rate is about 14% to ensure the energy supply of the solar road stud. The solar road stud must be hard, if the anti-friction is not hard enough, it is easy to be grind.

1/12/2014 · Oxidation complicates the use of organic molecular markers such as hopanes for source apportionment, since receptor models assume markers are stable during transport. We report the oxidation kinetics of organic molecular markers (C25−C32 n-alkanes, hopanes and steranes) in motor oil and primary organic aerosol emitted from a diesel engine at
