ram-air

基本解釋

To its credit, the high-end Adamo does include 4 GB of built-in RAM, double that of the Air.
值得稱道的，高端阿達莫不包括4 GB的內(nèi)置內(nèi)存，增加了一倍的空氣。
I enjoyed the svelte look and featherweight status of my 11-inch MacBook Air ($999, 1.6 Intel Core 2 Duo, 2 GB RAM, 64 GB flash storage), launched last October.
我自己也買了一臺11寸吋的MacBook Air筆記本（價格999美元，1.6英特爾酷睿2處理器，2G內(nèi)存，64G快閃儲存）。這款11寸吋小本于去年10月推出，我非常喜歡它纖細的外觀和輕薄的機身。
You can configure the MacBook Air with more storage and more RAM (neither of which are user-upgradable, so you'll need to do this ahead of time if you're going to at all).
你可以為MacBook Air配置更大的儲存器和內(nèi)存（但兩者都無法在用戶端進升級，所以你得提前將其升級。）
