The use of electronic nicotine products is rapidly evolving among the United States(US)youth.Electronic nicotine products produce and deliver thousands of pulmonary toxicants and iritants different from combustible to...
Combustible / toxic gas detection and alarm system is composed of detector, alarm controller and audible and visual alarm. It is widely used in various industries, such as petroleum, chemical industry and gas. It is u...

Liquefied natural gas(LNG)is a kind of clean energy,and many LNG-powered vessels have been de-signed and built around the world.However,LNG introduces the potential risk of leakage and explosion accidents;thus,it is n...
In order to solve the issue that the combustible objects for cased telescoped ammunition (CTA) didn't burn completely during the combustion process, the microcellular combustible objects were foamed with numerous cell...
Combustible agricultural waste is a potential source of energy because of its high organic content and heating value.As China’s economy develops,energy demand increases while environmental protection becomes more str...

Exposure to diesel engine exhaust(DE) is a major concern in underground mines. It has been linked to cardiopulmonary diseases and is classified as a human carcinogen. The goal of this study is to assess DE exposures i...
One of the worlcrs largest reserves of fossil fuels--"combustible ice"--has come a step closer to commercial exploitation. China's Ministry of Land and Resources (MLR) announced on June 2 that the country's tria...
In this paper, we investigate a free boundary problem of a semilinear combustible system with higher dimension and heterogeneous environment. Such a problem is usually used as a model to describe heat propagation in a...
Existing fire test methods reply on measurement of the energy released rate to identify the combustion properties of a material. However, they are inadequate when assessing combustion characteristics of a composite ma...
In this paper, we investigate a semilinear combustible system ut-duxx = vP, vt-dvxx = uq with double fronts free boundary, where p ≥1,q ≥ 1. For such a prob- lem, we use the contraction mapping theorem to prove the ...
