摘要在廢舊聚烯烴的裂解反應中，聚丙烯的存在，可以提高輕油餾份的收率，增強反應的油化效果，本文稱之為聚烯烴裂解反應的增強效應。 -
At first, bubble flow image is acquired using laser and incandescence lamp respectively as light source and using ccd. according to different optics - dispersion character, threshold segmentation method is proposed to identify gas from the gas - water flow, which make steadfast base for further calculate void fraction. the precision of threshold directly affect the calculate precision of void fraction
文中分別採用激光片光源和影視燈照明，採用逐行掃描數字ccd攝像機獲取氣泡的流動圖像；根據氣泡和水對光的反射特性不同，提出採用閾值法識別圖像中的氣泡和水，從而為進一步計算摻氣濃度打下堅實的基礎。 -

採用硅膠作干層析柱填充物，用氯仿作展開劑和洗脫液，反復硅膠層析，對柄海鞘鞘囊氯仿浸提物進行分離、提取與純化，最後得到一淺黃綠色的油狀液體fraction （以下均稱f ） 。 -
These have proven to be elusive subjects of study because existing telescopes do not have the resolution to see within a fraction of a light year of the central supermassive black hole, where these little black holes are thought to be concentrated most heavily
事實已經證明，這是一個很難研究的課題，因為現有的望眼鏡不能看到在特大黑洞一光年以內的東西，那裡才是人們所認為的、小黑洞聚集的地方。 -
Although compact fluorescent light bulbs are relatively expensive, they use a fraction of the energy of normal bulbs, which means your electricity bills will fall. they also last eight times longer than ordinary bulbs
雖然前者價錢較貴，但耗用的能源較普通燈泡小，不但節省電費，耐用程度比普通燈泡高出八倍。 -
Organic c in the soil profiles were measured as in total and fractionated into microbial biomass - c, water - soluble organic - c, light - fraction organic - c, and heavy - fraction organic - c. the amounts of microbial biomass - c, and water content in soil profiles were consistently analyzed. the aim of this study was to investigate interactions between the accumulation of soil organic c and vegetation successions in the region, in a purpose to improve understanding on how changes in soil conditions affect vegetation successions in the region
通過分析植被演替各個群落（棄耕地先鋒群落、草本群落、灌叢群落、早期森林群落、遼東櫟群落） 0 50cm深度內土壤有機碳、微生物碳、水溶性有機碳、輕組有機碳、重組有機碳的變化規律及相互關系，初步探討了植被正向演替過程中土壤有機碳的積累與變化規律。 -
Man never directly perceives motion with speed greater than a tiny fraction of the speed of light.
人們從來未曾直接覺察到速率比光速大極小一個因子的運動。 -
A very small fraction of the sun ' s light and heat is emitted in such directions that after passing unhindered through interplanetary space, it hits the earth
只有很小一部分太陽的光和熱由此方向釋放出來，並且未被阻擋，穿越星空，來到地球。 -
With the depth increasing, the content of microbial biomass - c, the content of the water - soluble organic - c, the content of light - fraction organic - c, and the content of heavy - fraction organic - c go down on the soil profiles. ( 4 ) the high significance linear regression between microbial biomass - c and soil organic c is discovered ( y = 27. 978x, r2 = 0. 9498 * * ). furthermore, the changing degree of microbial biomass - c is remarkably higher than soil organic c. so microbial biomass - c can indicates the change of soil organic - c in the course of vegetation succession
（ 4 ）土壤微生物碳與有機碳之間存在極顯著線性正相關關系（ y = 27 . 978x ， r ~ 2 = 0 . 9498 ~ （ * * ） ） ，而且微生物碳的變化幅度大於有機碳的變化幅度，因而可以用來指示植子午嶺植被演替過程中土壤有機碳積累與變化被演替過程中土壤有機碳的變化。 -
The high significance linear regression between light - fraction organic - c and soil organic - c is also discovered ( y = 0. 1914x, r2 = 0. 9121 * ). but the changing degree of light - fraction organic - c is lower than soil organic c. so light - fraction organic - c can not indicates the change of soil organic c in the course of vegetation succession
（ 5 ）土壤輕組有機碳與有機碳、重組有機碳與有機碳之間都存在極顯著線性正相關關系（ y = 0 . 8138x ，擴一0 . 9522 」 ） ，但二者佔有機碳比例的變化趨勢卻剛好相反。
