論文概念辨析：Aim 和 Objectives 有什么區別？
The aim of a study states the outcome that you hope to achieve from your study. It is a broad statement of the overall goals of your study and indicates where you hope to reach at the end of your research. The aim of your research encapsulates what you wish to find out or prove through your research.
研究的 Aim，是指你想從研究中獲得的結果，比較泛地講了研究想要做到什么地步，達到什么目的。你想通過研究證明什么、發現什么，都屬于 Aim 的范疇。
On the other hand, research objectives lay down the steps, that is, the specific or direct actions that you will take to achieve your aim. The objectives of your research lay down specific milestones or stages that you will reach in order to accomplish your goals. While the aim is a broad goal that you wish to accomplish, the objectives are small, precise steps that will guide you through your research path. In other words, the aim of your research paper states what you wish to achieve and the objectives indicate how you will achieve them, by identifying specific steps or milestones.Depending on the type of document you are writing, you might need to provide an aim, objectives, or both.
而研究的 Objectives 更偏向于操作步驟，換句話說，就是為了實現 Aim 而采取的具體行動。作者要在 Objectives 中規劃好各階段的目標。如果說 Aim是大目標，Objectives 就是小步驟。Aim 表達的是你想干嗎，而 Objectives 通過給出具體步驟來解釋要怎么做。作者有時兩樣都得寫，有時只用寫其中一個，具體還是要看論文類型。
The following example will help you understand the two terms better.
以下例子可能有助于你加深理解。
