Jake confirmed that he had personally seen some of the classified maps showing dramatically altered future coastlines, and also confirmed the possibility of a very advanced high-speed 'shuttle-like' system that connected many places, like the US and Australia under the Pacific Ocean - a longstanding but always uncorroborated rumor within the UFO community that had acquired semi-mythological status since the startling reports of John Lear and William Cooper in the late 1980s.

杰克证实，他曾亲自见过一些机密地图，上面显示了引人注目的、改变了的未来海岸线，同时他确证，未来可能会出现非常先进的高速运转的"梭子般的"（shuttle-like）系统，来连接许多地方，就像美国和太平洋下面的澳洲-这是一个长期存在的，但却总是未被证实的、流传在UFO社区里的传闻

Methods: According to the mechanism of cough reflex, the c-fibres's role in the respiratory system, and the principle of isosterism. Here, a peripheral antitussive LD was regarded as a lead compound. Amino functional groups, as substituents at the 1-hydroxy group of the racemate of LD, were introduced into the structure of the molecule. These novel compounds were confirmed by 1H-NMR, MS spectrum. Their antitussive activities were studied on mice in sequential method. The EDT50, the stimulating time that caused cough by NH3 on half of mice, were measured. Then could caculated the ratio R between the EDT50 of the treated groups and control group.
