摘要

需要强调的是,本文的主要结论并不是任何特定的参数在任何特定的尺度上都是线性的,而是在品牌群之间甚至群内品牌之间的斜率、截距甚至线性上都存在着非常显著的差异。事实上,尽管有几个品牌在算术或对数尺度上似乎是充分线性的,但它们的表现显然彼此不同。也有相当有力的证据表明,凝结物和尼古丁在同一尺度上不是线性的,凝结物在对数尺度上近似线性,尼古丁在算术尺度上近似线性。在上述的基础上,很明显,品牌的排名在任何参数的测量值的基础上,将在很大程度上取决于对接长度在该参数的测量。因此,很明显,交货的国际比较需要在新的对接长度标准下重新确定交货,而不是使用单一函数关系进行数学操作。从目前的研究中无法确定HCN合适的函数关系的形式,需要额外的实验。统计设计和分析证明了对其他三个参数的模型判别是有价值的。

A Study of Chemical Deliveries as a Function of Cigarette Butt Length
Abstract It should be emphasized that the major conclusion of this paper is not that any particular parameter is linear on any particular scale, but that there are highly significant differences in slope, intercept and perhaps even linearity between brand groups and even brands within groups. In fact, although several brands do seem to be adequately linear on either arithmetic or logarithmic scales they very clearly do behave differently from each other. There is also quite strong evidence that condensate and nicotine are not linear on the same scale, with condensate being approximately linear on the logarithmic scale and nicotine approximately linear on the arithmetic scale. On the basis of the above it is quite clear that the ranking of brands on the basis of measured value of any parameter will depend strongly on the butt length at which the parameter was measured. It is therefore apparent that international comparison of deliveries requires redetermination of deliveries at the new butt length standard rather than mathematical manipulation using a single functional relationship. The form of a suitable functional relationship for HCN cannot be ascertained from the present study and will require additional experimentation. The statistical design and analysis proved worthwhile in model discrimination for the other three parameters.
