慢性肾功能衰竭尿毒症（CRF）患者维持性血液透析治疗多采用挠动脉、头静脉吻合内瘘穿刺建立血透通道，个别原因直接动静脉穿刺或采用肱动脉、贵要静脉人造血管内瘘等措施。永久性瘘管穿刺点分为固定或2～3点交替使用以维护其使用寿命。经观察，穿刺点间距的选择与长期透析效率
Chronic renal failure uremic (CRF) patients with maintenance hemodialysis multi-use of the tortuous artery, the first venous anastomosis fistula to establish hemodialysis, for some reasons direct arteriovenous puncture or the use of brachial artery, intravenous artificial blood vessels such as fistula Measures. Permanent fistula puncture point is divided into fixed or 2 ~ 3 points to maintain its service life. After the observation, the choice of puncture point spacing and long-term dialysis efficiency

从激励学生开展实验操作的意识和动机、合理为学生创设实验操作的机会、合理选择操作的模式、做好操作材料的准备和指导归纳等五个方面进行了探讨。 动手操作自主探究学习能力数学是和现实生活联系密切的学科之一，数学知识来源于生产生活实际。新课程标准也对探究性学习作出充分说明，强调“数学学习内容应有利于学生主动地进行观察、实验、猜测、验证、推理和交流等数学活动”。所以，结合教学内容，经常给学生提供亲自参与实践
