  我国西部地区海拔较高,最高的机场位于稻城亚丁,标高4441米,也是世界最高的机场。东航安全管理教员钟文彬告诉《中国新闻周刊》,高原地区空气相对平原较为稀薄,飞机所需的升力对应的速度会更大一点。因此,遇到气流不稳时,颠簸也会更大,瞬间出较大偏差的可能性会比较大。

arrangement adapted for ready reference. It is true that the botanists of the 17th century and Linnaeus himself often spoke of facility of use as a great object to be kept in view in constructing a system; but every one who brought out a new system did so really because he believed that his own was a better expression of natural affinities than those of his predecessors. If some like Ray and Morison were more influenced by the wish to exhibit natural affinities by means of a system, and others as Tournefort and Magnol thought more of framing a perspicuous and handy arrangement of plants, yet it is plain from the objections which every succeeding systematist makes to his predecessors, that the exhibition of natural affinities was more or less clearly in the minds of all as the main object of the system; only they all employed the same wrong means for securing this end, for they fancied that natural affinities could be brought out by the use of a few easily recognised marks, whose value for systematic purposes had been arbitrarily determined. This opposition between means and end runs through all systematic botany from Cesalpino in 1583 to Linnaeus in 1736.

  凡事我们要辩证统一地看,这样的安排有好处,但也造成了问题。也就是,地方的一个机构、一个部门,要同时对上负责,还要同时对地方负责。如果地方应急的时候出现了很多命令,他就要考虑这个命令,是不是跟我上面的要求打架,他就容易配合衔接不起来。

“We are informed that on the 14th of August, about sixty miles on this side of the Big Biopiere [Bayou Pierre] River, Colonel Joshua Baker, a Mr. William Baker and a Mr. Rogers of Natchez, were robbed of their horses, traveling utensils, and about two thousand three hundred dollars cash. It seems the company had halted in the morning at a small, clear stream of water in order to wash. As soon as they had dismounted and gone to the water four men appeared, blacked, between them and their horses and demanded the surrender of their money and property, which they were obliged to comply with. Mr. W. Baker was more fortunate than his companions. A pack-horse, on which was a considerable sum of money, being frightened at the appearance of the robbers, ran away, and they being in haste to escape could not pursue. Mr. W. Baker recovered his horse [pack-mule] and money. He, however, lost his riding horse, etc. Colonel Baker and Mr. Rogers came to the first settlement, where they procured assistance and immediately went in pursuit of the villains. It is to be hoped they will be apprehended. One of them who was described by Colonel Baker, formerly resided at Red Banks. A brother of Colonel Baker, our informant, obtained this information from Mr. W. Baker, who lodged at his house [in Lexington, Kentucky] on Thursday night last.”

The authors of the oldest herbals of the 16th century, Brunfels, Fuchs, Bock, Mattioli and others, regarded plants mainly as the vehicles of medicinal virtues; to them plants were the ingredients in compound medicines, and were therefore by preference termed ‘simplicia,’ simple constituents of medicaments. Their chief object was to discover the plants employed by the physicians of antiquity, the knowledge of which had been lost in later times. The corrupt texts of Theophrastus, Dioscorides, Pliny and Galen had been in many respects improved and illustrated by the critical labours of the Italian commentators of the 15th and of the early part of the 16th century; but there was one imperfection which no criticism could remove,—the highly unsatisfactory descriptions of the old authors or the entire absence of descriptions. It was moreover at first assumed that the plants described by the Greek physicians must grow wild in Germany also, and generally in the rest of Europe; each author identified a different native plant with some one mentioned by Dioscorides or Theophrastus or others, and thus there arose as early as the 16th century a confusion of nomenclature which it was scarcely possible to clear away. As compared with the efforts of the philological commentators, who knew little of plants from their own observation, a great advance was made by the first German composers of herbals, who went straight to nature, described the wild plants growing around them and had figures of them carefully executed in wood. Thus was made the first beginning of a really scientific examination of plants, though the aims pursued were not yet truly scientific, for no questions
