与过去广泛采用的图解法相比有了非常大的进步。然而由于标准的滞后，原有的部分定义，就显得不够明确。如屈服点的定义，只有定性的解释，而没有定量的说明，很不适应计算机自动处理的需求。这就造成了：判断条件的各自设定就屈服点而言（以金属拉伸GB/T228-22为例）标准是这样定义的：屈服强度：当金属材料呈现屈服现象时，在试验期间达到塑性变形发生而力不增加的应力点，应区分上屈服强度和下屈服强度。上屈服强度：试样发生屈服而力下降前的高应力。

真空泵要连续运转，不得间断，若中间因事故、停电等原因停泵，要马上与贮槽真空层断开，否则真空泵油将倒流入夹层，造成污染事故。、真空泵运行时，要注意冷却水是否中断，泵油升温不超过4℃。、天冷时抽真空应移在室内进行，否则因室外温度太低，影响抽真空效果。、要注意真空泵的维护、保养。真空泵经常保持清洁，泵上不得放置其它物件。另外每抽一次要换一次油，（用1#真空泵油）这是因为抽真空运行时，夹层的珠光砂细沫极易被抽入真空泵气缸内，若不及时换油清洗，下次抽真空将会影响真空度，换油好在油温升高后进行，注意加油量，油多了，会引起启动困难，返油、喷油等不良现象，少了则影响真空度。
