釐清張力從物理學到詩學的變化；闡述張力主要是對立因素、互否因素、異質因素、互補因素構成的緊張關係結構；探討張力主要運行管道；張力的層級樣態（短長、分合、隱顯）；以及張力與詩意基本呈正相關的關係：當張力無限擴大時，詩語趨於晦澀；當張力無限解除時，詩語落入明白。最後對張力這一重要的詩學範疇與語言尺度做出增補：張力是詩語活動中局部大於整體的增殖，詩語的自洽能力以最小的「表面積」（容量）獲取最大化詩意。

In order to clarify the transformation of tension from the study of Physics, to Poetics, tension is to be discussed from the aspects of, opposing factors, negating factors, deviating factors and supplementing factors. By probing into the main operation channel of tension-its level of state (length, movement, subtlety); poetry itself will present to have positive correlation with tension: when tension expands, the poetic language becomes obscure; when tension relives, the poetic language then becomes clear. Moreover, coverage on the importance of tension on the scope of Poetic and scale of language is emphasized on, where the poetic language will obtain its maximum implication by realizing that tension is the value gained when parts of it is greater than the overall concept, and that the self-consistency of the poetic language would need the smallest quantity of ”surface area” (Capacity).
