It tracks the animal's position, speed, and how fast they're accelerating, step by step.

它追踪动物的位置、速度以及他们每一步的加速度。

Try making a variable that tracks the train’s position.

尝试制作一个跟踪火车位置的变量。

In Switzerland, a small school of zebrafish swim around a circular path, with a camera overhead tracking their position.

在瑞士，一小群斑马鱼绕着圆形路径游动，头顶上的摄像头跟踪它们的位置。

Or if you're into photography, there's a watch face for that, with apps like Lumi to help you track the sun's position.

或者如果你喜欢摄影，Lumi等应用可以帮助你追踪太阳的位置。

The best guess is that it tracked astrological positions, like the lunar calender and predicted events, such as the seasons.

最好的猜测是它跟踪占星位置，如农历和预测事件， 如季节。

Astronomers spent the next two decades meticulously tracking the position of Uranus across the sky, but it still didn't fit Bouvard's predictions.

Submersible pilots also rely upon a technique known as inertial navigation, using a system of accelerometers and gyroscopes to track their position and orientation in relation to a known starting point and velocity.

潜水飞行员还依靠一种被称为惯性导航的技术，使用一个由加速度计和陀螺仪组成的系统来跟踪他们与已知起点和速度相关的位置和方向。

The technique relies on the negatively charged nature of DNA. The researchers applied a charge to the system to move the arm around and tracked its position using fluorescent signals picked up by microscopy.

该技术依赖于 DNA 的负电荷性质。研究人员向系统施加电荷以移动手臂并使用显微镜拾取的荧光信号跟踪其位置。
