4.0 Abstract
Measurement theory (= quantum language ) is formulated as follows.

Measurement theory says that
In this chapter, we devote ourselves to the linguistic interpretation ($\S$3.1) for general (or, quantum) systems.
$\bullet$ Describe every phenomenon modeled on Axioms 1 and 2 (by a hint of the linguistic interpretation)!
Again recall that, as mentioned in $\S$1.1, the main purpose of this book is to assert the following figure 1.1:
