In geometry and science, a cross section is the non-empty intersection of a solid body in three-dimensional space with a plane, or the analog in higher- dimensional spaces. Cutting an object into slices creates many parallel cross-sections.
In physics, the cross section is a measure of the probability that a specific process will take place in a collision of two particles. For example, the Rutherford cross-section is a measure of probability that an alpha particle will be deflected by a given angle during an interaction with an atomic nucleus.
something that has been cut in half so that you can see the inside, or a model or picture of this. 橫截面（圖），橫斷面（圖），剖面（圖）. a cross-section of the human heart 人體心臟剖面圖. a small group that represents all of the different types within the total group. 典型，代表.
A cross section is the shape we get when cutting straight through an object. The cross section of this object is a triangle. It is like a view into the inside of something made by cutting through it. This is a cross-section of a piece of celery.
截面（英語： Cross section ）為一幾何學名詞，是指一三維空間下的物體和一平面相交所產生交集。截面的面積稱為截面積，被截面分離的物體稱為截面體。 祖暅原理說明若兩個固體對應的截面積相等，則其體積相等。
The meaning of CROSS SECTION is a cutting or piece of something cut off at right angles to an axis; also : a representation of such a cutting. How to use cross section in a sentence.
A cross-section is a shape that is yielded from a solid (eg. cone, cylinder, sphere) when cut by a plane. For example, a cylinder-shaped object is cut by a plane parallel to its base; then the resultant cross-section will be a circle. So, there has been an intersection of the object.

A cross-section represents an object’s intersection with a plane along its axis. A cross-section is formed by cutting a solid (such as a cone, cylinder, or sphere) with a plane. If a plane parallel cuts a cylinder-shaped item to its base, the resulting cross-section is a circle. As a result, the item has intersected.
The cross section is the part of the plane that overlaps with the 3D figure. A cross section of a tree trunk is circular. Cutting different geometric figures with a plane or cutting the same geometric figures from different angles or positions may create cross sections of different shapes.
