熱射點火
英文
hot-shot ignition-
These aren ' t the mercenaries who parachute into hot spots, guns blazing, for cold cash. but they ' re controversial nonetheless
這些公司不是那種外國雇傭軍，為了冰冷的金錢而空降到熱點地區，槍口噴射著火焰。但是，他們仍然引起了人們的爭議。Aimed at tube curve by sun shining, it analyzes and calculates the instance of curve when tube up and down face have difference in temperature, and discourses upon it influenced degree to cannon firing accuracy. for hot spread asymmetry caused tube curve, it explains it ' s form cause. for irregularly hot stress acting tube curve, it stressfully analyzes effect of body tube wall thickness difference
重點分析了身管熱彎曲產生機理，針對太陽照射下的身管彎曲，分析計算了身管上下表面存在溫度差時的彎曲情況，論述了其對火炮射擊精度的影響程度；對于散熱不均引起的身管彎曲說明了其形成原因；對于不規則熱應力作用下的身管彎曲重點分析了身管壁厚差的作用。The resistivity of the films drops compared with the as - grown films, but the temperature of maximum magnetoresistance reaches 287k, very close to the room temperature. therefore it is not only an important improvement to fabricate the cmr bolometer which can work near room temperature, but also a prospective research for other applications such as magnetic - sensors, spintronics devices and infrared detectors
同時，退火后薄膜的電阻率明顯下降，外加5t磁場時，最大磁電阻率溫度點上升到287k ，接近於室溫，這不僅為製作室溫超巨磁電阻測輻射熱儀打下了堅實的基礎，也為其它許多器件的應用提供了可能。Abstract : thermal ignition of black powder and single base powder by an electrically heated wire was experimentally studied. critical igniti on current through the wire and time - to - ignition was measured. temperatures of the wire when ignition of powders occurred were calculated
文摘:用實驗方法研究了黑火藥和單基發射藥在電熱絲作用下的點火問題，測出了實驗條件下兩種藥劑的臨界點火電流及點火延滯期，並推算出了點火的電熱絲溫度。In this article, constituting some the equations which reflect the flow law and building and applying many mathematical models of physical and chemical reactions in the the plasma ignition : applying k - two equations turbulence model to calculate the turbulence parameter supplying simplied reaction systerm model and applying eddy break - up model and p - i thermal radiation model. with these reasonable simplied modles, numerically simulating the flow field in the plasma ignition. during the numerical simulation, applying the body - fitted coordinates for the complex geometry of the computional field ; using the mixing format to disperse the equations ; applying simplec algorithm method to solve the equations ; using above models and methods, it can get flow field distribution ; including temperature, pressure, turbulent kinetic energy and its dissipation rate, turbulent viscosity, velocity, density. these results are significant to design and improve the plasma ignition
