YOU SAID:

It is the total absence of material in the elements (matter) in a certain space or place, or the lack of content inside a container. By extension, the condition of a region where the density of particles is very low, such as interstellar space, is also called a vacuum; or that of a closed cavity where the pressure of air or other gases is less than atmospheric.

INTO JAPANESE

それは、特定の空間や場所の要素（物質）に物質がまったくないこと、またはコンテナ内の内容が不足していることです。ひいては、星間空間のように粒子の密度が非常に低い領域の状態は、真空とも呼ばれます。または、空気または他のガスの圧力が

BACK INTO ENGLISH

It is that there is no substance in the element (substance) of a specific space or place, or that the contents in the container are insufficient. As a result, the state of a region where the density of particles is very low, such as the interstellar space, is also called a vacuum. Or the pressure of air or other gas

INTO JAPANESE

特定の空間や場所の要素（物質）に物質がない、または容器の中身が不足しているということです。その結果、星間空間のように粒子の密度が非常に低い領域の状態は、真空とも呼ばれます。または空気または他のガスの圧力
