In this there was a substratum of truth.

面有一个真理基础。

Firmly narrowing upward from this wealthy but inconspicuous substratum was the compact and dominant group which the Mingotts, Newlands, Chiverses and Mansons so actively represented.

从个富有但不显眼底层坚定向上缩小是明戈特、纽兰兹、奇弗斯和曼森家族如此积极代表紧凑而占主地位群体。

Mr Chivers overlays a street map with colours representing the different substrata - " half eccentric artwork, half primary-school science project" - which becomes a springboard for his digressions.

奇弗斯先生用代表不同底层结构不同颜色，描绘出一张街道地图——“既像古怪艺术品，又像小学科学项目”——成了他跳板。

While he did not answer she began to feel the old hypnotism of his intelligence, sometimes exercised without power but always with substrata of truth under truth which she could not break or even crack.

虽然他没有回答，但她开始感受到他智慧古老催眠术，有时没有力量，但总是在真理之隐藏着真理底层，她无法打破甚至破解。
