As a domain expert in nuclear physics, I can tell you that the term "strongest nuclear force" typically refers to the strong nuclear force, also known as the strong force or strong interaction. This is one of the four fundamental forces of nature, and it is the force that holds atomic nuclei together. The strong force is indeed the strongest of the four fundamental forces in terms of its effect on nucleons (protons and neutrons) at very short distances.

The strong force is responsible for binding quarks together to form protons and neutrons, and it also binds protons and neutrons together to form atomic nuclei. It is a non-Abelian gauge theory, which means that the force carriers themselves (gluons) can interact with each other, creating a very complex and strong binding effect.

The strong force is approximately 100 times stronger than the electromagnetic force, which is the force that causes charged particles to repel or attract each other. However, the strong force has a very short range, typically on the order of 10^-15 meters, which is roughly the size of an atomic nucleus.

Here is the answer in English, followed by the translation in Chinese, with a separator as requested:

English Answer:
The strongest nuclear force is the strong nuclear force, also known as the strong force or strong interaction. It is one of the four fundamental forces of nature and is responsible for holding atomic nuclei together. The strong force is the most powerful force when acting on nucleons at very short ranges.

Chinese Translation:
最强的核力是强核力，也称为强作用力或强相互作用。它是自然界四种基本力之一，负责将原子核保持在一起。在非常短的距离上对核子（质子和中子）起作用时，强作用力是最强大的力。

In the context of binding protons and neutrons together to form atomic nuclei, the strong interaction is called the nuclear force (or residual strong force). In this case, it is the residuum of the strong interaction between the quarks that make up the protons and neutrons.read more >>
