The desensitization degree of emulsion explosives (EE) was calculated with the peak pressure of explosion shock waves tested in water. To an explosive, the less the desensitization degree, the better the compression resistance, so the compression resistance of an explosive can be compared and analyzed quantificationally with the desensitization degree. The influence of an emulsifier on the pressure desensitization of EE was studied, including the content and category of emulsifiers. Three kinds of emulsifiers (Span-80, compound emulsifier, and T-152) were used in the tests. The experimental results show that both the content and category of emulsifiers make a great effect on the pressure desensitization of EE. The desensitization degree of EE reduces with the emulsifier content being increased, but there is an optimal content of an emulsifier for the compression resistance of EE. While the content of Span-80 reaches 4wt%, the desensitization degree of EE becomes a minimal value, and augments somewhat if the emulsifier content is increased more. That is to say, the compression resistance of EE becomes the highest while the content of Span-80 is 4wt%, and the compression resistance will decline if the content of Span-80 is increased more. The compression resistance of the explosive emulsified by compound emulsifier is the highest among all the explosives, when the content of the whole components and manufacturing engineering are kept invariable. 相似文献

This article presents the results of a time-limited psychological relief effort using eye movement desensitization and reprocessing (EMDR) following the attacks on the World Trade Center on September 11, 2001. Clients made highly significant positive gains on a range of outcome variables, including validated psychometrics and self-report scales. Analyses of the data suggest 2 broad conclusions: EMDR is a useful treatment intervention both in the immediate aftermath of disaster as well as later; the longer treatment is delayed, the greater the level of disturbance experienced by clients. Also discussed are problems in conducting research during mass disaster response situations. A demonstration of an analog to a wait-list control group is provided.

Technology is ubiquitous in our occupational, educational and leisure lives. A fear of interacting with technology can therefore have a major impact on the quality of an individual’s life. This is particularly salient within education as an inability to maximise the benefits of technology may limit academic achievement and subsequent opportunities in life. The severity of the anxiety induced by technology has lead to a plethora of research into the prevalence of ‘technophobia’. This term may have clinical relevance and has been found to be comparable in severity to more traditional phobias [Thorpe, S. J. &; Brosnan, M. (in press). Does computer anxiety reach levels which conform to DSM IV criteria for specific phobia? Computers in Human Behavior]. This paper presents two studies examining the effect of clinically-derived treatments upon levels of anxiety induced by technology. Study 1 was a 10-week selective desensitisation programme with 16 participants (eight computer anxious, eight non-anxious). Over this period computer anxiety and coping cognitions were significantly improved in the computer anxious group and become comparable to those of the matched non-anxious controls. Study 2 was a single treatment session for anxiety. Thirty individuals identified as anxious were assigned to either a one-session treatment (n = 9) or non-treatment (n = 21) group. Initially, both groups were significantly more anxious than the non-anxious control group (n = 59). Subsequent testing established that over the period of an academic year the reduction in anxiety was three times greater in the treated group than the non-treated group such that by the end of the year the treated group no longer differed from the control group, whereas the non-treated group remained significantly more anxious. The implications and limitations of the studies are discussed. 相似文献
