by volume

基本解释

For example, if you like wood, Hyperion is not the biggest tree in the world. By volume, there are bigger hunks of living wood in the California forest.
比如说，如果你喜欢木头，和伯龙神不是最大的树，从体积来看，加州有更大的树……（学会插图片了……）
Balance can be balance by location of objects such as windows on a house, balance by volume or sizes of objects, balance by color (like desired brightness in a room).
平衡可以通过对象的位置实现，如一间房子的窗户，还可以通过对象的体积或大小达到平衡，还有通过颜色取得平衡（如室内亮度）。
Using a model that simulates how light, water, and air interact, Seitz found that microbubbles could double the reflectivity of water at a concentration of only one part per million by volume.
塞茨利用一个模型模仿了光、水和空气是如何产生相互作用的，他发现：按体积计算，密度仅为百万分之一时，微型气泡可以使水的反射率加倍。

"You know the thickness, tolerances of wood has to be exactly right for the right tone, and volume of a soundboard has to be measured exactly, and that's done mostly by ear.
The important point here is it's not just a probability, it's a density, so we know that it's a probability divided by volume.
它不是概率,而是概率密度，所以我们知道，它是密，除以体积，我们。
