根据以下材料，回答题： 某综合建筑，地上6层，建筑高度22．70m；地上一层为商铺、地上二至四层为办公，地上五至六层为旅馆。该建筑内设有室内外消火栓系统、火灾自动报警系统、消防应急照明、消防疏散指示标志、灭火器等消防设施及器材。室内消火栓系统如图2-27-1所示。 该建筑的室内消火栓系统采用I临时__给水系统。检测和验收时发现：设有符合要求的消防水池一座，两台符合要求的消防水泵从池中取水供给高位消防水箱和消火栓系统，系统设有三条竖管和一个环网向18个消火栓供水，消火栓系统管网上设有两组消防水泵接合器，室内消火栓安装在走道上，室内消火栓间距不大于30m。室外消火栓给水系统流量为201／s，室内消火栓给水系统流量为151／s，室内同时动用消防水枪数为2支，竖管最小流量为101／s，消火栓竖管直径为DN80，办公区室内消火栓采用DN50单阀单栓。商业和旅馆区室内消火栓采用DN65单阀单栓。消火栓箱内配置软管卷盘。消火栓箱内安装有报警按钮，按动后红灯点亮，并向消防控制中心报警，消防控制中心以硬线点对点的控制方式手动直接控制消火栓泵的启停。现场检测时拍摄的部分照片如图2-27-2、图2-27—3所示。

请分析本案例情景描述中和图2—27-1中的错误。

What do chicken pox, the common cold, the flu, and AIDS have in common They’re all disease caused by viruses, tiny microorganisms that can pass from person to person. It’s no wonder that when most people think about viruses, finding ways to steer clear of viruses is what’s on people’s minds.
Not everyone runs from the tiny disease carders, though. In Cambridge, Massachusetts, scientists have discovered that some viruses can be helpful in an unusual way. They are putting viruses to work, teaching them to build some of the world’s smallest rechargeable batteries.
Viruses and batteries may seem like an unusual pair, but they’re not so strange for engineer Angela Belcher, who first came up with the idea. At the Massachusetts Institute of Technology (MIT) in Cambridge, she and her collaborators bring together different areas of science in new ways. In the case of the virus-built batteries, the scientists combine what they know about biology, technology and production techniques.
Belcher’s team includes Paula Hammond, who helps put together the tiny batteries, and Yet-Ming Chiang, an expert on how to store energy in the form of a battery. "We’re working on things we traditionally don’t associate with nature." says Hammond.
Many batteries are already pretty small. You can hold A, C and D batteries in your hand. The coin-like batteries that power watches are often smaller than a penny. However, every year, new electronic devices like personal music players or cell phones get smaller than the year before. As these devices shrink, ordinary batteries won’t be small enough to fit inside.
The ideal battery will store a lot of energy in a small package. Right now, Belcher’s model battery, a metallic disk completely built by viruses, looks like a regular watch battery. But inside, its components are very small, so tiny you can only see them with a powerful microscope.
How small are these battery parts To get some idea of the size, pluck one hair from your head. Place your hair on a piece of white paper and try to see how wide your hair is pretty thin, right Although the width of each person’s hair is a bit different, you could probably fit about lots of these virus-built battery parts, side to side, across one hair. These micro-batteries may change the way we look at viruses.

How tiny is one battery part（　）

A:Its width is one tenth of a hair. B:It equals the width of a hair. C:It is as thin as a piece of paper. D:Its width is too tiny to measure.
