ecological engineering, volume 36, issue 5, may 2010, pages

697-702

road construction is an important cause of environmental

degradation, particularly in mountainous regions. however, re-

establishing vegetation cover at the construction site can

mitigate these problems, particularly on steep roadside slopes.

in the present study, we developed two new planting

techniques to increase vegetation cover on these slopes, in

which planters fill the holes in air bricks (i.e., bricks with large

holes that pass through the full depth of the brick) with soil,

then plant grass or herbaceous species in the soil. two

variants of this technique (one in which the air bricks form a

stairstep pattern, and another in which they form a smooth

slope) were tested in an area with a warm climate near

shennongjia (hubei province) between 2006 and 2008. the new

planting techniques promoted root growth, the development of

a continuous vegetation cover, and the production of

merchantable seeds compared with the conventional planting

technique. this suggests that the air brick technique is more

suitable for the study area, where the natural soils are thin, and

may prove suitable for similar areas elsewhere in the world.

the provisional results, based on 2 years of research, suggest

that the new techniques represent a potentially valuable

alternative for vegetation restoration, landscape conservation,

and road maintenance/management in mountainous zones

during and after highway construction. the techniques have

strong potential for use in other areas. in addition, they

provide a good example of using ecological

engineering to increase vegetation cover on steep roadside

slopes.

一个真正的推理方法来选择投资的混合动力汽车

technological forecasting and social change, volume 77, issue

4, may 2010, pages 649-661

arman avadikyan, patrick llerena

long term increases of petrol prices and the threat of a global

climate change have created in the automotive industry a new

competitive environment based on the development of more

sustainable technologies. using the real option reasoning lens

we provide a theoretical framework to better account for the

technological and market uncertainties and irreversibilities

that impact the investment and innovation decisions of

automotive firms supporting the development of more

sustainable vehicle technologies. we investigate the case of

hybrid vehicles in a transitional perspective by insisting on

their potential to influence the dynamic shaping of investment

decisions of firms in the car industry. we consider the

hybridization strategy as intra-project and inter-project

compound growth options to manage

electric vehicles: the role and importance of standards in an

emerging market

电动汽车：角色和在新兴市场的标准的重要性

energy policy, volume 38, issue 7, july 2010, pages 3797-3806

stephen brown, david pyke, paul steenhof

there is an increasing need for new and greater sources of

energy for future global transportation applications. one

recognized possibility for a renewable, clean source of

transportation fuels is solar radiation collected and converted

into useable forms of electrical and/or chemical (hydrogen)

energy. this paper describes methods for utilizing and

combining existing technologies into systems that optimize

solar energy collection and conversion into useful

transportation fuels. photovoltaic

(pv)-electrolysis (solar hydrogen) and pv-battery charging

systems described in this paper overcome inefficiencies

inherent in past concepts, where dc power from the pv system

was first converted to ac current and then used to power

electrical devices at the point of generation, or fed back to the

grid to reduce electricity costs. these past, non- optimized

concepts included efficiency losses in power conversion and

unnecessary costs. these drawbacks can be avoided by

capitalizing on the unique feature of solar photovoltaic devices

that match their maximum power point to the operating point

of an electrolyzer or a battery charger without intervening

power transformers. this concept is illustrated for two systems

designed, built, and tested by general motors for fueling a fuel

cell electric vehicle and charging an automotive propulsion

battery. based on this research, we propose a scenario in

which individual home-owners, businesses, or sites at remote

locations with no grid electricity, can capture solar energy,

store it as hydrogen generated via water electrolysis, or as

electrical energy used to charge storage batteries. such a

decentralized energy system provides a home refueling option

journal of cleaner production, volume 18, issue 9, june 2010,

pages 908-916

jonathan leaver, kenneth gillingham

a multi-regional integrated energy systems model is

developed to assess the economic impact of hydrogen fuel cell,

hydrogen internal combustion, and battery electric

technologies on the economy of new zealand. base case

results suggest that a hydrogen fuel dominant vehicle fleet

offers economic savings over a conventional fleet but requires

the largest sequestration capacity as 75% of hydrogen fuel

production is derived from fossil fuel. when the oil price is

varied from us$$120 to us$$240 per barrel in 2030, and the

carbon tax varied from us$$30 to us$$90 per tonne of co2

equivalent, the change in

savings ranges from ?65% to +25%.

how to succeed in a job interview

如何在求职面试中取得成功

面试在求职过程中的作用

取得面试成功的因素：仪表、举止谈吐、能力、专业知 识、自信、

实事求是

… students who are about to graduate have to face the

challenge of being interviewed while trying to find employment.

people looking for ajob usually attach great

importance to job interviews. doing well in a job interview

means a good chance of being employed. with little working

experience, how can we succeed in a job interview?

in my opinion, firstly, we should leave the employers a good

impression an what we were, how we talk as well as how we

behave in public. secondly, we should not be nervous, for over

ncrvousness will lead to uncertainty of your ability. being

confident can bring you to success. when you are asked

something about the job you want, you should answer it as

fully as possible according to what you know. thirdly, honesty

is a virtue. being honest about your present situation and

never make any boastful statemeat.

i hope everyone will have a good chance and win success in

the interview. then all of us can get our ideal jobs.
