Based on the sha lo wan profiler data at 0740utc, the vertical shear at around 1, 100 ft was close to 8 kt per 100 ft. although this was lower than the 8 kt per 100 ft which has been used in the windshear warning system at the old kai tak airport, the increase in head wind was nonetheless significant due to the steep climb angle
根據沙螺灣的氣流剖析儀在0740utc錄得的資料顯示，在約1 ， 100尺的垂直切變接近每百尺每小時8海里。雖然此切變低於以往啟德機場的風切變警報系統所用的每百尺每小時8海里，但因為陡峭的爬升角度，令到逆風的增加變得顯著。 -
They were, says mr stephen, and the end was that the men of the island, seeing no help was toward as the ungrate women were all of one mind, made a wherry raft, loaded themselves and their bundles of chattels on shipboard, set all masts erect, manned the yards, sprang their luff, heaved to, spread three sheets in the wind, put her head between wind and water, weighed anchor, ported her helm, ran up the jolly roger, gave three times three, let the bullgine run, pushed off in their bumboat and put to sea to recover the main of america
「此語不差」 ，斯蒂芬先生曰， 「其結果，本島男子發現負情女子異口同聲，無可救藥。遂建造舟筏，攜家財登船，桅桿盡皆豎起，舉行登舷禮，轉船首向風，頂風停泊，揚起三面帆，在風與水之間挺起船首，起錨，轉舵向左，海盜旗迎風飄揚，三呼萬歲，每次三遍，開動艙底污水泵，離開兜售雜物之小舟，駛至海面上，航往美洲大陸。 」 -

The shear experienced by the departing aircraft was due to vertical shear as the plane passed through the low level jet. based on the winds measured on - board a flight departing 8 minutes earlier, there was a rapid increase in head wind component, from 13 kt at 1, 420 ft to 39 kt at 3, 100 ft
起飛的飛機所遇到的風切變是由於該機經過低層急流的垂直切變所引致，根據一架在8分鐘前起飛的航機量度到的風速，顯示逆風由1 ， 420尺的每小時13海里急速增加到在3 ， 100尺的每小時39海里。 -

The optimum inclination angle is between 15 ~ 20, the length of thermosyphon will not change the phase - change heat transfer coefficient of the evaporation section and the condensation, which will enlarge heat transfer area of thermosyphon and increase the heat exchange capacity. the head - on speed of wind only stranger the heat transfer of the evaporation section and the condensation section. the experiment shows that the mathematic model closely fits to the thermosyphon, moreover, the one key to resolve the thermosyphon effect lies in decreasing the thermoresistance of evaporating section and condensation section. this study can provide directions and experience in the future research
傾斜角越大，熱虹吸管總熱阻越大，最佳傾角在15 20之間;充液率過多或過少都會對傳熱性能產生不利影響，對于本實驗採用的1 . 75m 、 2m 、 2 . 5m 、 3m熱虹吸管，最佳充液率在20 % 35 %之間;管長對傳熱也有影響，管長不改變熱虹吸管蒸發段和冷凝段的換熱系數，只增加了熱虹吸管的換熱面積，增大換熱量;迎面風速的大小，起到強化熱虹吸管蒸發段和冷凝段換熱的目的。 -
