心率指心脏每分钟搏动的次数, 它能够反映心脏的工作状态。正常心率决定于窦房结的节律性, 成人静息时约60～100 次/ min , 平均约75次/ min。心率可因年龄、性别及其他因素而变化。初生儿心率约130 次/ min , 随年龄增长而逐渐减慢, 至青春期乃接近成人的心率。女性心率比男性稍快 运动员心率较慢。成人安静心率超过120 次/ min 者, 为心动过速 低于40 次/ min 者为心动过缓。心率受植物性神经和体液因素调节。-Heart rate means the number of pulse per minute, it can reflect the work of the state of the heart. Normal heart rate determined by the rhythm of the sinoatrial node, resting adult is about 60 ~ 100 times/min, an average of about 75 times/min. Heart rate may be due to age, gender and other factors change. Heart rate of newborn infants of about 130/min, growth has gradually slowed down with age, to adolescence adult heart rate is near. Women slightly faster rate than men athletes slow heart rate. Quiet adult heart rate over 120 times/min, and for the tachycardia less than 40 times/min for bradycardia. Heart rate by the plant regulate neural and humoral factors.

该论文以CAN总线的实时性问题为研究对象，在系统分析了CAN总线协议的特点并指出CAN总线的主要局限性的基础上，对CAN总线网络通信的实时性问题进行理论分析。 -CAN bus to the paper issues real-time study in the analysis of the characteristics of CAN bus protocol and pointed out that the main limitations of CAN bus based on CAN bus network communication theory in real-time analysis of issues .

在顺序存储结构中，利用编号表示元素的位置及元素之间孩子或双亲的关系，因此对于非完全二叉树，需要将空缺的位置用特定的符号填补，若空缺结点较多，势必造成空间利用率的下降。在这种情况下，就应该考虑使用链式存储结构。-Storage structure in order to use the element number that the location and elements of the relationship between children or parents, so for non-complete binary tree, the location of the vacancy will be required to use specific symbols to fill the vacancy if more nodes, it is bound to cause decline in utilization of space. In this case, we should consider the use of the structure of chain stores.
