麻烦大家帮我翻译一下这篇文章，谢谢了，我急用啊！

In many assay procedures , a titration
seves as the final step, being preceded by other chemical reactions ,
separation techniques , or other manipulations .It may be noted here that
titrimetry is a widely applicable approach for quantitative analysis , and is
often coupled with other methods.
One of the advantages of titrimetry as an
analytical approach is that it is an absolute method of analysis . The meaning
of this statement will not be fully clear until we have studied methods lacking
this attribute ,but it simply mean that , by titrimetric analysis , the purity
of a sample compound can be determined without reference to a separate specimen
of that same compound (whose purity might itself be in doubt). For example , a
sodium hydroxide solution can be standardized against primary standard grade
potassium biphthalate , and then the purity of a sample of acetic acid can be
determined by titration with the NAOH solution . Thus the purity of the acetic
acid has been obtained without making any assumptions about acetic acid(that is , without using acetic
acid as a primary standard) . Such assumptions were , of coutse , made about
the potassium biphthalate , and independent evidence must be available to
support them .
A titration is feasible when (1) the titration
reaction is rapid compared with the speed of titration ; (2) its equilibrium
constant is large enough to give a sharp “break” at the end point ; (3) a
method of end point detection is available . Whether or not the titration
should be used for a particular analysis will depend upon many factors ,including
the sensitivity required , possible interfering substances that would also betitrated and alternative methods of analysis.

在许多分析程序中，使用滴定法一般都是作为最后一步,是在其他化学反应,.分离技术,或其他操作之前。这里要注意的是，滴定分析是一个广泛适用的方法进行定量分析且经常与其他方法结合。
滴定分析的优点之一是,它是一个绝对分析法。这句话的意思是将不会完全清楚,直到我们研究方法缺乏这个属性,但它只是意味着,通过滴定分析,纯度.样本的化合物可以确定没有提及一个单独的标本
同样的化合物(其纯度可能本身是在怀疑)。例如,一个氢氧化钠溶液可以标准化的反对主要标准等级
钾苯二甲酸氢酯,然后纯度样本中的乙酸可以作为主要标准)。这样的假设是针对苯二甲酸氢钾的,而且必须有独立的证据可用于支持他们这些理论。
一个滴定法是可行的当(1)滴定反应迅速与速度的滴定;(2)它的平衡常数是足够给一个锋利的“打破”在终点;(3)方法检测可用的终点。是否滴定法应该用于一个特定的分析将取决于许多因素,包括所需的敏感性,可能的干扰物质,也和分离替代的分析方法。
