偏心率（Eccentricity）是用來(lái)描述圓錐曲線軌道形狀的數(shù)學(xué)量，定義為曲線到定點(diǎn)（焦點(diǎn)）的距離與到定直線（準(zhǔn)線）的距離之比。對(duì)于橢圓，偏心率即為兩焦點(diǎn)間的距離（焦距，2c）和長(zhǎng)軸長(zhǎng)度（2a）的比值，即e=c/a（偏心率一般用e表示）。軌道偏心率即天體運(yùn)行軌道的的偏心率。

See every heart beat on the monitor, just like in ER rooms. Measure your heart rate instantly! Instant Heart Rate uses your iPhone's camera to detect the pulse from your fingertip - leveraging similar technique as used in pulse oximeters. Place the tip of your index finger on the iPhone’s camera, and in a couple of seconds your pulse will be shown. Instant Heart Rate will beep with your pulse. A real-time chart will show you every heart beat. Join over 25 million users who are already using it. Features: - Heart pulse measurement - Real-time PPG graph - Continuos or Auto-Stop mode - Heart Rate Zones - Pulse waveform graphs - One week data storage and tags - Export data for registered users - Sharing to Twitter and Facebook - StandUP test for fatigue and fitness testing as an in-app purchase. NOTE: Works best on iPhone 4/4S/5 because it has flash. On iPhone 3GS and iPod touch it has to be used in good lighting. NOTE: Make sure that your fingertip completely covers the camera lens. Press gently, since pressing too hard reduces blood flow in your finger and it's harder to get a result. Make sure that your fingers are not cold. This app is for recreational and fitness use only!
