在许多情况下，常需要对同种类聚合物的特性粘度进行大量重复测定，如果都按此法操作，每个样品至少要测定3个以上不同浓度溶液的相对粘度，这是非常繁琐的，而且需时较长，尤其在所得样品量极少的情况下，就难以用此法求得高聚物溶液的，为此，人们找到了更快速的近似方法，即"一点法"。

Conceptually, the most obvious sample point within a fundamental period is often referred to as the pitch mark. Usually pitch marks are selected as the local maxima or minima of the audio waveform. In the previous example of pitch determination for the tuning fork, we used two pitch marks that are local maxima. On the other hand, in the example of pitch determination for human speech, we used two pitch marks that are local minima instead since they are more obvious than local maxima.

在观察音讯波形时，每一个基本周期的开始点，我们称为「音高基准点」（Pitch Marks，简称 PM），PM 大部分是波形的局部最大点或最小点，例如在上述音叉的范例中，我们抓取的两个 PM 是局部最大点，而在我的声音的范例中，由於 PM 在局部最大点并不明显，因此我们抓取了两个局部最小点的 PM 来计算音高。

The problem of the determination of the final geometry of the single-layer reticulated shell with zero element internal force is also successfully solved by using this method. Based on the research on the shape determination theory a conclusion has been obtained: the distribution of the initial self-internal-force vector determines the initial shape of an assembly which has form finding problem.

通过对形状确定问题的研究，可得出如下的结论：体系自应力分布矢量的方向决定体系初始态几何；体系自应力分布矢量的大小只影响体系的零状态几何；体系各个单元的截面尺寸设计也将影响体系的零状态几何。

The determination of cytokinin levels is a primary and basic approach in the cytokinin studies.

The optimal measuring conditions were investigated. The results indicated that the catalytic reaction to Pt and bromocresol purple was the first-order reaction. The apparent activation energy was 217.4kJ/mol and the maximum absorption wavelength of fading reaction was at 434 nm. The linear range of Pt was 0.16-4.0μg/L and the detection limit was 2.5×10^(-11)g/mL. Most of common ions had no interference with the determination, while ten multiples of Ru, Rh and Os had interference with the determination of Pt. Therefore.

选择了最佳测定条件，实验结果表明，催化反应对铂和溴甲酚紫为一级反应，反应的表观活化能为217.4kJ/mol，褪色反应的最大吸收波长为434nm，方法测定R哪的线性范围为0.16~4.0μg／L，检出限为2.5×10^(-11)g/mL，大多数常见离子不干扰测定，10倍以上的Ru，Rh和Os对测定有干扰，可在测定前分离除去。
