定义1设IRn中的向量组A:a1,2,…an 线性无关,β是IR中中任一向量, 则,a1,a2,…,an线性相关(因为这 是n+1个n维向量,向量个数大于向量维数),于 是根据第三章第二节定理2知道向量可以用a1, a2…a唯一线性表示 =k1a1+k2a2++knan 我们称向量组A:a1,a2,…,an为空间 IR的一组基(basis),把数k1k2,k称为 向量在基a1,a2,…,an下的坐标

This is an admirably concise and clear guide to fundamental concepts in physiology relevant to clinical practice. It covers all the body systems in an accessible style of presentation. Bulleted checklists and boxed information provide an easy overview and summary of the essentials. By concentrating on the core knowledge of physiology, it will serve as a useful revision aid for all doctors striving to achieve postgraduate qualification, and for anyone needing to refresh their knowledge base in the key elements of clinical physiology. The author’s own experience as an examiner at all levels has been distilled here for the benefit of postgraduate trainees and medical and nursing students. Dr Ashis Banerjee is Consultant in Emergency Medicine and serves as Examiner for those undertaking their MB, BS, MRCS and MFAEM examinations
