某苯胺生产企业对技术改造问题进行经济可行性分析。目前企业投产的两条生产线,每年生产苯胺合计25吨,但随着设备的老化和技术的落后,每年的成本逐渐增加,产品品质也有所下滑。为了解决存在的问题,需耗资5000万元进行技术改造。技术改造时,拆除旧设备将会损失200万元,而这些旧设备的残值为50万元。技术改造完成后,每吨苯胺的成本将由原来的450元降低至425元,假设苯胺行业的标准投资效益系数为0.3。根据以上资料,回答下列问题:

在计算技术改造方案的总投资时,应该考虑的因素是()。

A.因技术改造需新追加的投资额

B.技术改造中拆除的旧设备、旧设施等造成的损失金额

C.技术改造的贷款利息

D.拆除的固定资产同收利用的价值

Online clothes shoppers will be told exactly what size is best. for them using new software which combines with their web camera or smart phone to form a“3D tape measure”.

Scientists from Surrey University and design experts from the London College of Fashion are developing a program which can take precise (精确的) waist, hip, chest and other measurements from camera images.

Using the person’s height as a starting point,the software will be able to build up a 3D image and estimate their size at various different points on the body, based on their overall proportions.

The result will be a more accurate sizing guide than previous systems based on waist size or a “small/medium/large”scale, which rely on limited measurements and the buyer’s perception of their own body size.

Shoppers and retailers(零售商)who choose to sign up for the project could save millions of pounds a year in postage costs by removing the need to order multiple sizes of the same garment(服装) and send back ill-fitting clothes, researchers claimed.

The project, sponsored by the Engineering and Physical Sciences Research Council(EPSRC), is expected to be brought to market within two years.

After choosing an item, the shopper will activate the software, enter their height, stand in front of their webcam or smart phone in their underwear and take a photograph.

The software will not store or transmit the image to the internet, but will use it to judge the person’s dimensions at various points on their body.

Philip Delamore of the London College of Fashion said:“The potential benefits for the fashion industry and for shoppers are huge. Currently, it’s common for online shoppers to order two or three different sizes of the same item of clothing at the same time, as they’re unsure which one will fit best.”
