A series of internal documents from the late 1970s and early 1980s shows that BAT at least thought about applying this knowledge to cigarette design. A research report from 1979 puts it thus: There are three major design features which can be used either individuallyorin combination to manipulate delivery levels; filtration, paper permeability, and filter-tip ventilation. A conference paper from 1983 says, The challenge would be to reduce the mainstream nicotine determined by standard smoking-machine measurement while increasing the amount that would actually be absorbed by the smoker. Another conference paper, from 1984, says:(5)We should strive to achieve this effect without appearing to have a cigarette that cheats the league table. Ideally it should appear to be no different from a normal cigarette...
英美公司上世纪70年代末、80年代初的一系列内部文献表明,该公司至少曾考虑过将这一知识用于卷烟设计。1979年的一份研究报告上这样说道:可分别或联合应用与设计有关的三个要素,即过滤、烟卷包装纸的通透性以及过滤嘴的通气效果,来控制焦油和尼古丁的释放水平。1983年一份会议论文也提到,关键在于,要在提高吸烟者尼古丁实际吸收量的同时,减少可被标准检测方法测定到的含量。1984年另一份会议论文说:我们应当努力达到这一效果并能在检测中蒙混过关。

The constant current coulometry as a primary method is recognized in international. Based on Faraday's law of electrolysis, it has been successfully used to determine purity of arsenic trioxide. The measuring results depend directly on the reliability of measuring physical quantities and fundamental constants expressed in SI units, and do not need a reference material for comparison.
高精密库仑滴定法是国际上公认的基准测量方法,该方法根据法拉第电解定律,通过质量、电阻、电动势、时间等基本物理量及法拉第常数来进行三氧化二砷纯度的测定,直接溯源到国际SI单位,不需要用标准物质进行比对。

To explore the possibility of early and rapid diagnosis of mycosisby detecting the fungal autofluorescence. Methods: To culture M. furfur and M. japonica standard strains on Dixonmedium at 32℃, and to study the autofluorescence of colonies in 2nd, 4th, 6th, 8th, 10th day under Laser Scanning Confocal Microscopy (LeicaTCS-SP2 LSCM). To study the variation of autofluorescence whenMalassezia colonies were put in 3% glutaraldehyde, pH4.0 HCL, 10% KOH, fluconazol solution, 0.3% methylene blue separately. To detect theautofluorescence of C. albicans, S. schenchii, T. rubrum, T. tonsurans, A.terreus, A. fumigatus cultured on Sabouraud dextrose agar.
