The earliest and reliable Castanopsis fossil records date back at least to Eocene, and subfamily Castaneoideae fossil records found from Paleocene, it is indicated that appearance of Castanopsis is not later than Paleocene . All fossil records of Fagaceae and Castanopsis report from the Northern Hemisphere and their main distribution regions are in the Northern Hemisphere . It can be concluded that the Northern Hemisphere is the center of origin of Fagaceae and Castanopsis . However, owing to the discrepancy between fossil data and results of modern botany research as well as scarcity of fossil data from key area, precise center of origin of Castanopsis cannot be inferred.

栲属在地质历史上有着比现在广泛的分布，最早、最可靠的栲属化石记录发现于始新世地层，栗亚科化石在古新世就有发现，化石记录表明栲属起源的时间不晚于古新世，所有的壳斗科及栲属的化石都发现于北半球，现代分布也主要在北半球，壳斗科及栲属起源于北半球可以确认，由于化石证据与现代植物学的研究结果有较大差异以及关键地区化石证据的不足，具体的起源地尚不能肯定。

The carbon dioxide produces the main way is fossil fuel massive burning, now mainly through enhances the fossil fuel the energy use factor, the use low-carbon or the non-carbon emerging energy took the fossil fuel the substitute, as well as the carbon dioxide collection and the storage realize the carbon dioxide to reduce the platoon.

二氧化碳产生的主要途径是化石燃料的大量燃烧，现在主要通过提高化石燃料的能源利用率，使用低碳或无碳的新兴能源作为化石燃料的替代品，以及二氧化碳的收集和储存来实现二氧化碳的减排。

The modern system of agriculture, which depends on the consumption of large quantities of fossil fuel, will be forced to change to a system where the interactions between organisms and environment and matter cycling are properly used for 3 reasons: 1 the depletion of readily available fossil fuel resources, 2 the level-off of the growth and yield response of crops with the increase in the use of fertilizer, agrochemicals and big machinery, and 3 the degradation of the environment along with the consumption of fossil fuel and its derived agrochemicals.

目前，现代化的农业生产系统建立在大量燃料的消耗上，虽然西方发达国家在近半个世纪的发展过程已经证明这是一种见效快、经济产值高的生产方式，但是随着在世界范围内可持续发展观念的日趋重视，这种生产方式的弊端也逐渐地受到人们的注意。1原有农业生产方式需要消耗大量的燃料资源；2虽然肥料、农药和大型机械的应用不断提高，但近几年农作物的生产和产量表现出停滞状态；3燃料及其副产品的不断使用导致环境逐渐退化。

Of course, automotive fuel changing from gasoline and diesel into gas fuel is also carried out blazingly everywhere in our country. Because automotive gas-fuel supplying system is yet not self-contained, and now a large of running vehicles by gasoline and diesel are the largest consumers of petroleum and source of pollutants, so vehicles by liquefied fuel being transferred into Gasoline/Gas amphibious-fuel or Diesel-Gas dual-fuel vehicles is the best way of automobile using gas fuel in our country now.

当然，我国各地也兴起了汽车燃料油改气的热潮，由于我国车用气体燃料的供给基础设施建设远未完善，并且目前在用的大量汽、柴油车是我国的石油消耗大户和最重要的污染源之一，所以我国目前最现实的做法是把大量的汽、柴油车改装为气体燃料／汽油两用燃料汽车或气体燃料—柴油双燃料汽车。

Supposes in 4,600,000,000 years perpetual flow in this, actually has had any, is already unable to recount; Only then from ancient stratum, discovery life process surviving vestige, but also might the testimony a wee bit remote past, such as: Early zoology and botany fossils and so on trilobita fossil, fish fossil, ferns, as well as after dinosaur fossil, fossils of bird, primitive time animal and human ancestor's fossil, but also had in the ancient times human history civilization corpse body with non-body vestige and so on, these vestiges nearly surmounted the entire Earth's life evolution history.

在这假定46亿年的长河中，究竟发生了什么，早已无法述说；只有从古老的地层中，发现的生命过程残存的遗迹，还可以见证一丁点儿的遥远过去，诸如：三叶虫化石、鱼化石、蕨类等早期动植物化石，以及之后的恐龙化石、鸟化石、原始时代动物及人类祖先的化石，还有古代人类历史文明中的尸体躯壳与非躯壳遗迹等等，这些遗迹几乎跨越了整个地球的生命演变史。

The fossil collections are important both scientifically and historically, with exceptionally well-preserved specimens from the Midlands and many other famous fossil localities in the UK, and throughout the world.The museum has some of the finest collections from the Wenlock Limestone of Dudley, famous for its fossils that lived 420 million years ago when the area was covered by a shallow, warm, tropical sea that enabled a highly diverse ecosystem to develop. From the rocks of the old Midlands Coalfields are important collections of fossil plants, fish, insects, arachnids, fossil footprints and animal tracks.

Hitherto mankind has relied on fossil fuel for a major part of its energy supply. Obviously the reserve of fossil fuel is by no means unlimited and will eventually be exhausted after decades. Hence, so far as long-term viewpoint is concerned, it is of importance to utilize the abundant and elean solar energy as an alternative energy source. Stimulated by this objective, studies on the preparation of suitable thin semiconductor films of larger size using simpler methods have attracted increasing interests.

从应用角度看，目前人类利用的矿物燃料其储量终究有限，而太阳能广泛存在，作为一种新型的能源，就长远的现点而言，具有巨大的潜力和广阔的前景，近些年来，研究用简单的方法制备大面积的化合物半导体薄膜材料，越来越受到重视，我们采用电沉积的方法在Ni、Ti以及导电玻璃等基底上沉积了多种硫属化合物半导体材料。
