从远处看,这些基本成分看上去极为相似,因此 DNA 的每一部分的基本形状都是相同的 — 著名的沃森克里克双螺旋结构。
From a distance, these building blocks look very similar, so every piece of DNA you look at has the same overall shape—the famous Watson-Crick Double Helix.
最经典的例子莫过于生物学中的双螺旋结构和物理学中的基本方程。
Examples include the double helix in biology, and the fundamental equations of physics.
这里分析了在安装尺寸基本确定条件下圆柱形螺旋压缩弹簧的高精度设计与调整。
The paper analyses the high precision design and adjustment of cylindrical spiral compressed spring under condition of installation dimension being ascertained basically.
Just the very basic level of the spiral.
这只是整个螺旋的最基本层次。
