我們無法停止壓力，但可以控制壓力對我們的影響。活用FREEDOM模型與SOS法則，科學地管理壓力，改變大腦對壓力的反應方式，調整至最佳狀態，讓保護生命的「生存腦」與理性思考的「學習腦」成功合作，與壓力共生，完成想追求的目標。每個人的大腦中都有一個警鈴，在感應到緊急時，警鈴就會啟動身體的壓力反應系統，進入自我保護的狀態，幫助面對挑戰、保持警覺並生存下去。壓力不是敵人，壓力真正的問題在於人們不知道大腦警鈴「啟動」後該如何緩和，使警鈴變得過於敏感，容易過度反應甚至誤報，讓大腦陷入長期且不必要的壓力反應，引發各種失控行為。失敗的壓力管理，會讓人在「生存腦」的影響下持續緊張，失去自控力，無法運用「學習腦」正常思考與解決問題。真正有效的壓力管理不只是放鬆，而是明確感受到自己握有掌控權。想成功管控壓力，就必須知道如何正確安撫、緩和並重設大腦警鈴，阻止壓力反應惡化成情緒崩潰，不讓極端活躍的大腦警鈴綁架你整個大腦、身體以及生活。過度把重點放在抑制壓力反應，告訴自己「要放鬆」、「不要擔心」、「別再抱怨了」，只是在發送「我無法掌控目前的壓力源」的訊息，只會加劇警鈴發作。大腦警鈴唯有在確定我們已經安全，或即便無法完全解決眼前危機但可以掌控時，才會停止輸送壓力化學物質、交還身體控制權。我們需要告訴警鈴，你知道它在擔心什麼，知道該做什麼並有能力處裡，才能從生存模式切換到學習模式，這就是壓力管理最重要、也是最容易遺漏的步驟──刻意專注在對你而言最重要的事情上，搞清楚最要緊的是什麼，找到核心價值與目標。專精情緒控管的心理醫師朱利安．福特博士，與長期輔導遭受重大壓力創傷者的喬恩．沃特曼結合腦神經科學研究、多年臨床與諮商經驗，說明大腦在壓力之下會如何變化，以及如何控制與巧妙運用大腦警鈴，改變大腦對壓力的反應方式：►以FREEDOM模型優化大腦，調整至最佳狀態•專注（Focusing）•辨識導火線（Recognizing triggers）•發揮情緒力量（Empowering your emotions）•實踐核心價值（Exercising your core values）•制定最佳目標（Determining your optimal goals）•做出最佳選擇（Optimizing your choices）•做出貢獻（Making contribution）►運用SOS法則，幫助大腦進入壓力控制

How to define the vector division has been plagued by people. We redefine the fraction , where represents an arbitrary vector, and extend it to discuss the differentiability and integrability of two or more variables function. In this book we directly exploit the definition of derivatives for two variable functions. According to our research, we discover various forms of the Mean Value(Vector) Theorems and the Fundamental Theorems of Calculus for multiple integrals. This book adds a new understanding to the field of multi-variable calculus and thus helps those who are working in the subject.We divide our research into three sections in this book. In Chapter 1, by defining the line derivector and plane derivector, we explain the chain rule for differentiation of multi-variables function, differential and the mean vector theorem. In Chapter 2, we illustrate the formula derivation of i) line derivector for a 2-variable function, ii) line derivatives for 2-variable functi
