The phrase "a rule that describes" is correct and usable in written English.
You can use it when referring to a guideline or principle that explains a particular concept or behavior.
Example: "In mathematics, a rule that describes the relationship between the angles and sides of a triangle is known as the Pythagorean theorem."
Alternatives: "a principle that outlines" or "a guideline that explains".
On the other hand, the Clar formalism, i.e., a rule that describes the stability of polycyclic systems, assists the interpretation of the reactivity of multinuclear aromatics towards oxidation.
"In dynamical systems, we study themes that evolve during time with a rule that describes the transition of one moment to the next," he said.
RF: For Fama and Lucas and their followers, if an economist gives you a rule that describes how outcomes will actually unfold, then there's only one rational way to think about the future.
The ones on the left conform to a pattern, or rule that describes them, and the task of the problem-solver is to find this pattern, or rule.
Nonetheless, there is no universal rule that describes which intervals might be more important in a scale than others; thus we treated all intervals equally.
Sometimes they conform to a different pattern (as is the case in the above example), while in some cases the rule that describes them is simply the negation of the rule on the left.
In order to translate the network interactions depicted in the diagram of Figure 1 into a dynamic discrete model, namely a time- and state-discrete dynamical system, the state transitions for each species must be specified by assigning an update rule that describes how the species's state will be updated at the next time step based upon the states of its inputs at the current time step.
A nonlinear hardening rule that describes a general yield surface change for frame members is proposed.
We have developed a syntax with a set of rules that describes the more than 5000 minimotifs in the MnM database.
The software assigns a minimum depth to each rule that describes the depth required for the rule to be completed.
