Earlier this year, NASA's Solar Dynamics Observatory caught a glimpse of a huge snakelike tendril of magnetic plasma on the sun, extending hundreds of thousands of miles across the surface.

年初，美国宇航局(NASA)的太阳动力学观测卫星捕捉到太阳上磁场等离子体巨蛇般的卷须状物，它沿太阳表面绵延数十万英里。

The gestural dynamics of the painted surface energize and transform the 'true-to-life' photographic image, giving it a mysterious dimension.

绘画表面肌理的动感令“逼真”的摄影图像充满活力，令其演变并拥有一种神秘的尺度。

Torque vectoring enables optimum use of the adhesion potential between the tyres and the road surface in all driving conditions, thereby extending the critical limits of the vehicle's driving dynamics.

At that point the fluid-dynamics equivalent of a titanic arm-wrestling match will get under way, with the surface vessels' pumps trying to push the mud down the well while the rising oil tries to push it out.
