“场”是一个现代物理学概念,是物质借以相互作用的介质,如电场、磁场。“气”是一个中国古代哲学概念,可以理解为生命力、能量。“气场”原本是一个神秘主义的概念。神秘主义往往借用一些科学术语来达到骗人的目的。“气场”被说得神乎其神,例如说它是人散发出来的能量,可以对别人发挥作用,影响别人的态度、行为,它甚至是有颜色的。这些都是骗人的鬼话。
但是现在“气场”这个词常常被借用来表示一个人的神态、举止、言谈等(尤指在公共场合)表现得轻松自在、自信自如,并因此让别人认为这是其内心的强大的自然流露。如果一个人的表现让别人感觉他很自信、很强大,就叫某人的气场强大/某人的气场很强,或者说某人有(强大的)气场。一般不说气场很微弱/很弱小,但是可以说“没有气场”。
"Field" is a concept of modern physics, the medium by which separate parts of matter interact, such as electric field, magnetic field. "Qi" is a concept of the ancient Chinese philosophy, being able to be understood as vitality, energy. "气场 aura" is originally a concept of occultism. Some occultists will steal certain scientific terms to deceive. "气场" was touted by them as mysterious (allegedly even having colors) and magical,such as being able to emit energy, and thus to impact on other people's attitude and behavior. These, of course, are lies.
But nowadays the word "气场" is often used to describe a person's demeanor. If a person's appearance, bearing, manners (especially in public) shows they are free and easy,confident and suave, and therefore make people think it's the natural presentation of the power of their spirit,you may say 某人的气场强大/某人的气场很强,or 某人有(强大的)气场。You don't usually say 气场很微弱/很弱小,but“没有气场(having weak spiritual power)”is possible.
