在本論文中我們去探討量子世界中的量測: 可被分為強測量及弱測量。由於弱測量在物理界的廣泛運用，本篇論文也摘錄了弱測量的應用，如: 量子態之弱值、雙態向量模型，並且去討論其在真實物理系統的可用性。再者，我們也提出了我們對於此兩種應用的物理詮釋。最後，我們運用我們所發展的理論模型去尋找弱量測和強量測之間的邊界，並且定義何為量測的完整性。

We study the measurement, which can be divided into two kinds of measurement: strong measurement and weak measurement in the quantum world. Due to the wide using of the weak measurement, the application of the weak measurement, e.g. , weak value (WV), two-state vector formalism (TSVF) are also mentioned in this thesis. The availability of the WV and TSVF in real physical systems is also discussed. Furthermore, we provide our comments on the physical interpretation of them. Finally, we had find the boundary between weak and strong measurement by our theoretical model, and defined the completeness of a measurement.
