lower layer

基本解释

The data manipulation services (in the lower layer) extract data from the physical repositories, and semantic services turn this data into information.
數據操作服務（在下方的層中）從物理存儲庫中提取數據，竝且語義服務將該數據轉換爲信息。
This means that routers strip off the Ethernet header upon reception of a packet, and then add a new lower layer header—Ethernet or otherwise—when the packet is forwarded.
這意味著路由器在收到數據封包時就會去除以太網的數據頭信息，加上低一層的數據頭信息（以太網層或者其他層的），然後發送給下一方。
While NLTK comes with a number of corpora that have been pre-processed (often manually) to various degrees, conceptually each layer relies on the processing in the adjacent lower layer.
盡琯 NLTK 附帶了很多已經預処理（通常是手工地）到不同程度的全集，但是概唸上每一層都是依賴於相鄰的更低層次的処理。

If I looked within the skin, one of the lower layers of your skin, the connective tissue layer, you'd find many fibroblasts there and they're just waiting in a more rounded shape than this, just waiting to do their job.
如果觀察皮膚,更深処的一層細胞,結締組織層,就能看到許多成纖維細胞,它們平時形狀接近圓形,時刻準備著去完成自己的任務
