向心力

Polarity,or action and reaction,we meet in every parto nature;in darkness and light;in heat and cold;in the ebband low o waters;in male and emale;in the inspirationand expkation o plants and animals;in the equation oquantity and quality in the luids o the anima1body;in thesystole and diastole20 the heart;in the undulations o luids-arjld--o sound:in the centriuga1and centripeta1gravity3;inelectricity,galvanism,and chemica1ainity.

两极性或作用与反作用在自然界中随处可见：黑暗与光明、炎热与寒冷、潮落与潮涨、雄性与性、动植物的吸气与呼气、动物体内的体液数量与质量的均衡、心脏的收缩与舒张、液体的波动和声音的起伏、离心力与向心力；此外在电荷、电流和化学的亲和性上也不难发现这点。

The Han People can remain indefectible at loss, thrive after danger, the key point is the culture, which includes the language, the productivity, the living style, the arts, the philosophy and even the value, all these are motivations from the inner of each Chinese people.

而文化基因的传承、复制、优化是它的不二向心力。我们汉民族在多次民族败北中之所以能够倒而不败、危而复兴，最关键的得力点，就是它的文化：语言、生产方式、生活方式、艺术、哲学、价值观等，起了海含而化之的内在之力（近现代我们的生产方式落后了）。

In addition to being a fun and intriguing gadget, the Powerball also is a great way to directly experience the Gyroscopic Effect (you know - angular momentum, linear momentum, centripetal force, precession and all those neat physics properties).

除了是一个有趣和迷人的小工具，威力也是一个好方法直接获得的经验的陀螺效应（你知道-角动量，动量，向心力，岁差和所有那些整齐的物理属性）。

Because the object and parts of the microcosmic particle accord with the definition of charge group, it holds that electron does circular motion by the force of charge group and the constant is Planck constant.

因为物体和部分微观粒子符合电荷群定义，所以认为电子是以电荷群的作用力为向心力做圆周运动，并且常数是普朗克常数。

The text used a circular motion model with charged particle to explain the photoelectric effect.Keywords: Planck constant, photoelectric effect, point charge, quantum mechanics, charge group

文中还用以电荷群的作用力为向心力做圆周运动的带电粒子模型解释了光电效应。
