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.

This circuit automatically turns on a
night lamp when bedroom light is
switched off. The lamp remains
‘on’ until the light sensor senses daylight
in the morning. A super-bright white
LED is used as the night lamp. It gives
bright and cool light in the room. When
the sensor detects the daylight in the
morning, a melodious morning alarm
sounds.

通过这一款选修课小系统，学生可以登入学生端进行选课及其他的操作，管理者通过登入管理端可以进行对选修课系统的数据的管理和维护。在学生端主要设置了3个基本功能：学生选课、学生情况、选课情况等；在管理端主要设置了9个基本功能：增加/删除学生、增加/删除课程、更改学分、填写成绩、学生情况、选课情况、保存数据等。这些功能基本上能满足选课的基本要求。此程序可以初步体现课程设计的目标。-An optional academic course or subject.
