求解什么是Biomass!!!!
|
||
剛得到一個(gè)新課題，課題范圍是using ionic liquids for processing of biomass. 在這個(gè)范圍里選一個(gè)具體話題寫個(gè)研究計(jì)劃/開題報(bào)告。關(guān)鍵是這個(gè)biomass。小妹搜了維基百科，講的好廣泛，是生物材料？？轉(zhuǎn)專業(yè)，有些基礎(chǔ)單詞不懂具體生物材料的處理嗎？？求解�。。。�！具體這個(gè)東西是什么 |

| 雖然大體上意思都差不多，就是生物量，但是還是要看你具體要干什么？生態(tài)學(xué)領(lǐng)域里就是指生物物體的質(zhì)量，也可以指代生物物體，比如說一顆玉米的全株重量就稱為生物量。這個(gè)概念可以擴(kuò)展到生物能源領(lǐng)域，例如用柳枝稷的全株做生物能源，做出來就叫生物質(zhì)能（biomass energy）。環(huán)境領(lǐng)域多半是固廢處理方面，垃圾中含有這些動(dòng)植物殘?bào)w，但是應(yīng)該同食物垃圾和排泄物垃圾還是有區(qū)別的，那種應(yīng)該稱為有機(jī)物固廢，雖然有機(jī)物固廢有些時(shí)候也包括生物質(zhì)。 |

這個(gè)東西范圍很廣，我找了一下定義，這個(gè)講得詳細(xì)點(diǎn)，你看看吧。 biomass 1. The total amount of living material in a given habitat, population, or sample. Specific measures of biomass are generally expressed in dry weight (after removal of all water from the sample) per unit area of land or unit volume of water. 2. Renewable organic materials, such as wood, agricultural crops or wastes, and municipal wastes, especially when used as a source of fuel or energy. Biomass can be burned directly or processed into biofuels such as ethanol and methane. See more at biofuel. A Closer Look When biologist J.B.S. Haldane was once asked if the study of life on Earth gave him any insights into God, he replied jokingly that his research revealed that God must have "an inordinate fondness for beetles." Haldane's comment is based on the fact that there are more beetle speciesalmost 400,000 now knownthan any other animal species. Beetles are just a fragment of the Earth's biomass, the matter that makes up the Earth's living organisms. Insects alonewhich comprise almost one million known species and perhaps millions yet to be discoveredcreate an amazing amount of biomass. The number of individual insects is about 10 quintillion (10,000,000,000,000,000,000). Insects probably have more biomass than any other type of land animal. In comparison, if the weight of the Earth's human population were added up, the biomass of the insect population would be 300 times as great. Biomass also refers to the organic material on Earth that has stored sunlight in the form of chemical energy. Biomass fuels, including wood, wood waste, straw, manure, sugar cane, and many other byproducts from a variety of agricultural processes, continue to be a major source of energy in much of the developing world. There are many who advocate the use of biomass for energy as it is readily available, whereas fossil fuels, such as petroleum, coal, or natural gas, take millions of years to form in the Earth and are finite and subject to depletion as they are consumed. |
