Early food technologies produced flat bread, hard biscuits, cheese and salted meat, allowing Roman legionaries to carry rations for several days. Canning was invented in the late 18th century in response to the French Government＇s offer of a substantial reward to the person whose invention would allow troops to carry their food when marching long distances. World War II saw further advances in the form of stable and palatable canned meals, compressed cereal bars, candy-coated peanuts and other innovative foods in US combat rations. Two significant technology breakthroughs in the second half of the 20th century have altered the form of military rations. Freeze drying matured as an industrial technology, allowing the production of long-life, light-weight rations. Flexible packaging, based on plastic laminates, led to reduced weight and less waste disposal through the development of retort pouched meals （meals in flexible packaging that have undergone heat sterilization）, which have largely replaced metal cans in combat rations. Improvements in quality of military rations, particularly their organoleptic properties, are emerging through application of innovative technologies such as high-pressure thermal processing, pulsed electric field, and microwave assisted thermal sterilization. Research and development of ＂functional foods＂, such as those containing added essential fatty acids or probiotics offers the potential to provide combat rations that can further improve soldier health and performance.展开更多

But there are low levels, pertinence is not strong, the introduction of fewer problems, it has both idea lag, the train of thought is not open, also has the system and mechanism is not perfect, imperfect laws and regulations and so on. We should start from mastering the characteristics of civil-military integration rule, renew the idea, and actively push forward scientific and technological personnel civil-military integration to a higher level, the deeper development.展开更多

An algebraic criterion for Hopf bifurcation is presented briefly and applied to find Hopf bifurcation point of the electrical system with automatic voltage regulator(AVR) dynamics in military vehicle. Hopf bifurcation controllers are designed for this electrical system by using wash-out filter,linear feedback,nonlinear feedback and their combination. The linear feedback control makes the system bring Hopf bifurcation at preferable parameter,the nonlinear feedback control modifies the type of the bifurcation,and the wash-out filter enhances the system damping,thus,the Hopf bifurcation is eliminated and the electrical system stability is ensured. Simulation results show the controller's validity.展开更多
