    1、目測與光學法
    1. Visual and optical methods.
    機械彈簧亮光的金屬外表上的油污可用肉眼和憑借放大鏡或光學顯微鏡進行調查。其缺點是金屬外表的鈍態氧化膜及極薄的油污會查看不到。對粗糙及不亮光的機械彈簧金屬外表,上述方法就顯得力不從心,但可經過用潔凈、皎白的棉花、布、紙對外表擦洗,然后調查其是否潔凈,以斷定機械彈簧外表是否潔凈.
    Oil stains on the bright metal surfaces of mechanical springs can be investigated with the naked eye and with a magnifying glass or optical microscope. The disadvantage is that the blunt oxide film on the metal surface and the thin oil stain will not be seen. For rough and dull mechanical spring metal appearance, the above method seems to be inadequate, but can be used clean, white cotton, cloth, paper to scrub the surface, and then investigate whether it is clean, to determine whether the mechanical spring appearance is clean.
    2、潮濕法
    2. Wet method
    潔凈的機械彈簧金屬外表是親水的,因而,能夠徹底被水潮濕,當機械彈簧金屬外表含有油污時,會呈現不被水滋潤的斷水區域。依據是否親水這一原理,除了更簡略常用的呼氣法和霧化器噴霧法外,還有以下幾種檢測手法。因為金屬的氧化膜也是親水的,因而,這類方法大多不能檢測出機械彈簧外表的氧化膜是否退凈。

    Clean mechanical spring metal surface is hydrophilic, and therefore, can be thoroughly wet by water, when the mechanical spring metal surface contains oil stains, it will present water-free areas. According to the principle of hydrophilicity, besides the most commonly used exhaling method and nebulizer spray method, there are several kinds of detection methods. Because the metal oxide film is also hydrophilic, most of these methods can not detect whether the mechanical spring surface of the oxide film is clean.

    3、油漆法
    3. Paint method
    將除油劑滴在機械彈簧外表上,然后蒸干,如無痕跡,外表是潔凈的,如呈現圓環則標明有油污存在。
    Drop the degreaser on the surface of the mechanical spring and steam it to dry. If there is no trace, the surface is clean. If there is a ring, it indicates the presence of oil.
    4、外表張力法
    4, appearance Zhang Lifa
    依據外表油污對其外表能的影響,經過金屬在一系列外表張力不同的試液中是否滋潤以斷定其外表能,據此判斷機械彈簧外表的潔凈程度。如配成從80%乙酸20%水)(V/V,下同)到1%乙醇99%水的系列溶液,其外表張力相應地從24.5×10-5N/CM增加到66.0×10-5N/CM。
    According to the influence of oil stains on the surface energy, whether the metal is moistened in a series of test solutions with different surface tension can be used to determine the surface energy, and the cleanliness of the mechanical spring can be judged accordingly. If a series of solutions were prepared from 80% acetic acid 20% water (V/V, the same below) to 1% ethanol 99% water, the external tension would increase from 24.5 *10-5N/CM to 66.0 *10-5N/CM accordingly.
