求翻译：标准观察者的三刺激值以观察者距离物体远近分为远距离，即2度角的三刺激值，近距离即10度角的三刺激值，用下标表示。是什么意思？

Tristimulus values ​​of the standard observer to observer distance object distance is divided into long-distance tristimulus values ​​in the 2-degree angle at close range, namely 10-degree angle tristimulus values, represented by the subscript.

The Standard Observer 3 stimulus value from an observer near and far objects in the distance, the 3 2-degree angle for a close up of the stimulus value is 10 degree angle, the value 3 with the next stimulus.

The standard viewer's three stimulation value far and near divides into the long-distance range by the viewer from the object, namely 2 degree angle three stimulation values, the short distance namely 10 degree angle three stimulation values, expressed with the subscript.

Tristimulus value of the standard observer to observer objects near and far into the distance distance, the tristimulus values of 2-degree angle, close the tristimulus values of the angle of 10 degrees, indicated by a subscript.
