Result: The electrophoretic mobility of labeled sample reduced compared to that of an unlabeled control sample.

结果：地高辛标记的TRAILR-2电泳能力下降，标记成功。

The whole column is placed in a thermostatically controlled heating jacket. A volatile sample is introduced into the column using a syringe, and an unreactive carrier gas, such as nitrogen, passed through it. The components of the sample will be carried along in this mobile phase. However, some of the components will cling more readily to the stationary phase than others, either because they become attached to the solid surface or because they dissolve in the liquid.

将整根柱子固定在一个可控制的恒温热罩内，用注射器把易挥发的待分析样品加入到柱子中，再令反应惰性的气体载体通过柱子，例如氮气，此时样品的各成份就会在流动相中移动，然而其中某些成份更倾向依附于固定相，可能的原因是它们能够依附于固体表面或是溶解于固体表面的液体中。

The analysis test is such a method that divides the unrehearsed objects into several types whose sample data have been achieved and establishes test according to some criteria, then tests and classifies the sample of unknown type.

摘 要 ：判别分析法是在已知研究对象分成若干类型并已取得各种类型的一批已知样品的观测数据，在此基础上根据某些准则建立判别式，然后对未知类型的样品进行判别分类。

So I specified the instance as humble as possible. In fact, we are discussing worldly things; we may take a sample that exists in the world. When we discuss unworldly things that belong to the spirit aspect or other space, we have difficulty in taking the worldly sample.

所以我才会尽量的以低微的事物为例，实际上，当我们讨论世俗的事务时，我们可以以实际存在的例子来说明；然而，一旦我们所讨论的是非世俗的；是属于精神层面或另一个空间的东西时，我们就很难再使用世俗的事物来加以说明了。
