• it is suitable for automobile inside decorations materials, for example: polyester foam, pvc, leather, textiles, nonwoven of materials such as air through rate and air resistance test.

  适用于汽车内饰物材料，例如：聚脂泡沫、pvc、皮革、纺织品、非织造布等材料的空气透过率与空气阻力的测试。

• its is actually acted upon by two forces , air resistance and friction resistance with the ice.

  这两种力量分别是，空气阻力和冰面摩擦力。

• i will skip the details of the numerical model, but here is a plot of a falling cylinder both with and without air resistance from 20 meters.

  关于数字模型的各种细节我就不多说了，但我们还是有必要看看下面两张图。 这两张图显示了在有和没有空气阻力的情况下从20米高处下落的圆柱的高度与时间比（左）及速度与时间比（右）。

• from the using point of view, the main technical performance to appraise the heat transfer performance of automobile radiator includes heat transfer performance, air resistance and water resistance.

  从应用角度看，评价散热器散热性能的主要技术指标有散热性能、散热器空气阻力以及水流阻力，分别简称为散热量、风阻及水阻。

• in the experiment of measuring gravity acceleration with a pendulum, a few error factors are existed, such as complex pendulum, air buoyancy, air resistance and initial displacement.

  在利用单摆测重力加速度实验中，有复摆、空气浮力、空气阻力、摆角等多种误差因素。

  一旦旗子被动过，由于月球没有大气，也就没有了空气阻力，它反而要过很久才能停下来。

• let air come in more easily - as a piston moves down in the intake stroke, air resistance can rob power from the engine.

  使空气更容易进入——在吸气沖程中，当活塞向下运动时，空气阻力将会剥夺引擎一定的动力。

• let exhaust exit more easily - if air resistance makes it hard for exhaust to exit a cylinder, it robs the engine of power.

  使尾气更容易排出——如果空气阻力使尾气难以排出气缸，这将会剥夺引擎的动力。

• air resistance can be lessened dramatically by putting two intake valves in each cylinder.

  在气缸上设置两个吸气阀就能大大减小空气阻力。

• drag is the force of air resistance pushing against a ball's motion and slowing it down, while lift is a force causing a ball to swerve off a straight path.

  拉力是一种物体在空气中所受到的阻力，它能产生与球运行方向相反的作用力，减缓球的运行速度，而升力则是一种能使物体偏离直线运行轨迹的力。

• the crystals are sometimes flat, and air resistance will cause them to float flatly, rather than knifing downward on edge.

  有时这些冰晶是扁平的，而空气会促使它们直截了当地在空气中漂浮着，而不是竖着像刀切一样地迅速落下。
