人和动物的肌肉具有惊人的力量,它能提起比它自身重许多倍的重物。经研究发现,肌肉所以能够收缩做功,主要靠肌原纤维。它在神经信号的刺激下,使肌肉变短、变粗,牵引肌腱运动。人的全身肌肉约有600余块,占人体重量的40%,有人估计,如果人体全身的肌肉朝一个方向收缩,其力量可达25吨!多么不可思议。近年来,军事仿生技术专家从动物和人体的肌肉得到启示,正在致力研究一种全新的人造“肌肉发动机”,以期提高飞机、坦克等兵器在战场上的机动能力和生存能力。目前,科研人员已用聚丙烯酸等聚合物制成了“人工肌肉”。这种聚合
The muscles of humans and animals are amazingly powerful, and they lift loads many times heavier than themselves. The study found that muscle contraction can do work, mainly by myofibrils. It stimulates the nerve signal, make the muscle shorter, thicker, traction tendon movement. About 600 human body muscles, accounting for 40% of the body weight, it was estimated that if the body’s muscles shrink in one direction, its strength up to 25 tons! How incredible. In recent years, military bionic technologists have enlightened the muscles of animals and human bodies and are devoting themselves to studying a completely new man-made “muscle engine” with a view to enhancing the mobility and survivability of aircraft, tanks and other weapons on the battlefield. At present, researchers have made polyacrylate polymers such as “artificial muscle.” This polymerization
