{"word":"催化剂","introduction":"化学上指能改变化学反应速率,而本身不受化学变化影响,不被消耗的物质。通常加速反应速率者,称为「正催化剂」;抑制、延缓化学反应者,称为「负催化剂」。生物体內的催化剂通常称为「酵素」,而生物体外的其他化学反应的催化剂,一般多为贵金属系,並可再回收利用。人体內的酵素就是催化剂的一种,如帮助淀粉分解的淀粉酵素,帮助血液凝结的凝血酵素等。 △触媒","prompt":"An animated illustration of a catalyst in a chemistry lab, symbolizing a substance that can change the rate of a chemical reaction without being consumed or undergoing any chemical changes itself. The scene features a vibrant, colorful lab setting with test tubes and bubbling liquids, showcasing the concept of a catalyst accelerating or inhibiting a reaction. The style is a playful and imaginative children's animation, emphasizing the important role of catalysts in chemical processes. The main focus is on the catalyst itself, surrounded by various chemical elements in the background.","explanation":"这幅插图展现了一个化学实验室中的催化剂,象征著一种能够在不被消耗或自行发生化学变化的情况下改变化学反应速率的物质。画面呈现了一个充满生气和色彩的实验室环境,有试管和冒泡液体,展示了催化剂加速或抑制化学反应的概念。这种风格是活泼而富有想像力的儿童动画,强调了催化剂在化学过程中的重要作用。画面主要集中在催化剂本身,周围环绕著各种化学元素。","alt":"An animated illustration of a catalyst in a chemistry lab, symbolizing a substance that can change the rate of a chemical reaction without being consumed or undergoing any chemical changes itself.
