Our first organic - synthesis experiments in 1996, and much more extensive research by thomas mccollom of the woods hole oceanographic institution, demonstrate that f - t reactions can build molecules with 30 or more carbon atoms under some hydrothermal - vent conditions in less than a day
1996年我們完成第一個有機合成實驗，加上伍茲赫爾海洋研究所的麥科洛姆所作的廣泛研究，兩者都顯示，在某種深海熱泉情境中，相關化學反應在一天之內就可合成含30個碳原子以上的長鏈分子。The second harmonic produced by a q - switched nd : yag laser with wavelength e = 532 nanometers ( nm ), pulse width 0 nanoseconds ( ns ) and repetition frequency i = 1 hz was used to bombard a highly pure solid hexagonal bn ( h - bn ) target ( 96 % ), with diameter of 2cm. in a vacuum chamber, boron nitride ( bn ) film was deposited on the single - crystal silicon substrate
利用高能脈沖激光（波長= 532nm ，頻率= 1赫茲，脈寬= 10納秒）在常溫下轟擊燒結的高純六方氮化硼（ h - bn ）靶，在真空反應室中將bn薄膜沉積在單晶硅基底上。A natural sounding headphone should have a gentle hump in the bass ( about 3 or 4 db ) between 40hz and 500hz. ( this compensates for the fact that headphones don ' t give you the physical punch that the sound from a speaker has ; so a slight compensation of increased bass is needed for natural sound. ) headphones also need to be rolled off in the highs to compensate for the drivers being so close to the ear ; a gently sloping flat line from 1khz to about 8 - 10db down at 20khz is about right
這大致是說，耳機頻響曲線在低頻40 - 500赫茲間有個小的隆起是正常的，因為耳機不能象喇叭那樣給人真實的低頻沖擊力，所以在這個低頻段加強一些，聲音反而自然逼真些.另外，為避免太刺激耳朵，耳機在1000赫茲起到耳朵聽力的極限20000赫茲間應該有衰減，到2萬赫茲處比平均輸出低8 - 10分貝是正常現象
