航海罗盘

To this day, the fundamental navigational tool was still known as a Compass Rose, its northernmost direction still marked by an arrowhead... or, more commonly, the symbol of the fleur-de-lis.

直到今天，最基本的航海工具依然被叫做"罗盘玫瑰"，它的正北方向一般会有一个法国百合的标志，当然，有时是一个箭头的标志。

The nautical techniques of Zheng He's fleet and Columbus' fleet, including their taking a ship's bearings, celestial navigation, meteorology and knowing wind, manipulating sail and using wind, compass and it's rose, nautical chart and map, log and measuring speed, sounding channel and so on, had reached the highest level in the sail time.

郑和船队和哥伦布船队的航海术，包括测定船位术、天体导航术、气象识风术、操帆驶风术、罗盘罗经术、海图地图术、计程测速术、航道探察术等等，都达到了帆船时代迄当时为止最高的水平。由于哥伦布的远航比郑和远航晚了八十多年，故哥伦布的航海术较之郑和又前进了一步。

In the next place we are to observe, that among the many things which I brought out of the Ship in the several Voyages, which, as above mention'd, I made to it, I got several things of less value, but not all less useful to me, which I omitted setting down before; as in particular, Pens, Ink, and Paper, several Parcels in the Captain's, Mate's, Gunner's, and Carpenter's keeping, three or four Compasses, some Mathematical Instruments, Dials, Perspectives, Charts, and Books of Navigation, all which I huddel'd together, whether I might want them or no; also I found three very good Bibles which came to me in my Cargo from England, and which I had pack'd up among my things; some Portugueze Books also, and among them two or three Popish Prayer-Books, and several other Books, all which I carefully secur'd.

另外，我还应该提一下，我从船上搬下来的东西很多，有些东西价值不大，但用处不校可是前面我忘记交待了。我这里特别要提一下那些纸、笔、墨水；船长、大副、炮手和木匠的一些东西，三四个罗盘啦，一些观察和计算仪器啦，日规仪啦，望远镜啦，地图啦，以及航海书籍之类的东西。当时我不管有用没用，通通收拾起来带上岸。同时，我又找到了三本很好的《圣经》，是随我的英国货一起运来的。我上船时，把这几本书打在我的行李里面。此外，还有几本葡萄牙文的书籍，其中有两三本天主教祈祷书和几本别的书籍。所以这些书本我都小心地保存起来。我也不应忘记告诉读者，船上还有一条狗和两只猫。

For navigation of ships and aircraft the radio range, radio compass, and radio time signals are widely used.

Zheng He fleet is "chop wood for the disk, the book's characters engraved Heavenly Stems and Earthly Branches, the needle floating in water, point to The Spectacle of Boats Sailing" is used in water gyrocompass, the Heavenly Stems, Earthly Branches, baguazhang, formed with the five elements, divided into 20 four different directions, if the needle and then taken into account, a total of 48 directions, each the equivalent of a modern compass azimuth 15 degrees, a total of 360 degrees, which the ancients used to guide navigation course has been quite a precise.

郑和船队是&斫木为盘，书刻干支之字，浮针于水，指向行舟&，用的正是水罗经，有天干、地支、八卦、五行配合而成，分有二十四个不同方位，如果再把缝针计算在内，一共四十八个方向，每一方位相当于现代罗盘的十五度，共三百六十度，这在古人航海中用以指导航向已颇为精确了。

Before the advent of the Chinese mariner's compass in the 11th century, the seasonal monsoon winds aided one in navigation, blowing north from the equatorial zone in the summer and south in the winter.

出现之前的中国航海罗盘在11世纪，季节性季风资助一个在导航，吹北从赤道区和南部的夏季，冬季。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.
