c.It needs repairing.它需要人修理.
It needs repairing.= It needs to be repaired.
It needs to repair.语法没错但意思不对,这里It是进行修理的主语,是它去修理其它东西,而非原意它需要人修理.

英语翻译
1.A transistor is constructed by creating a sandwich of differently doped semiconductor layers.The two most common types of transistors,the bipolar-junction transistor (BJT) and the field-effect transistor (FET) are schematically illustrated in Figure 2.1.This figure shows both the silicon structures of these elements and their graphical symbolic representation as would be seen in a circuit diagram.The BJT shown is an NPN transistor,because it is composed of a sandwich of N-P-N doped silicon.When a small current is injected into the base terminal,a larger current is enabled to flow from the collector to the emitter.The FET shown is an N-channel FET,which is composed of two N-type regions separated by a P-type substrate.When a voltage is applied to the insulated gate terminal,a current is enabled to flow from the drain to the source.It is called N-channel,because the gate voltage induces an N-channel within the substrate,enabling current to flow between the N-regions.
2.The type of simulation that is appropriate for a circuit depends on the type of circuit and how you plan to physically implement it.For example,analog,digital and mixed analog/digital circuits to be built as a PCB are,in general,best simulated with SPICE simulation.Digital circuits to be implemented in Programmable Logic Devices are usually simulated at the behavioral language level,most commonly with VHDL or Verilog HDL.For details,see HDLs or the documentation accompanying your VHDL or Verilog product form Electronics Workbench.For very complex digital devices,SPICE models are usually not practical.In these Cases,VHDL or Verilog is the preferred solution for simulating these devices.They can then be included as part of the system-level design by creating a symbol for schematic representation and using the HDL code for simulation models.For details,see HDLs or the documentation accompanying your VHDL or Verilog product from Electronics Workbench.
3.Even the most optimistic semiconductor researchers say that silicon-based computer chips may only have 15 years or so left in them.After that,it will be impossible to fit any more circuits onto these increasingly minute wafers to power inexorably smaller and smarter computers.Consequently,researchers are determined to figure out how to make complex microprocessors out of other materials.IBM made a significant breakthrough in August when physicists at its Thomas J.Watson Research Center,built the world’s first logic circuit out of a single long carbon molecule called a nanotube.Though the first laptop with nanotubes inside is still a long way off,the IBM invention “was a critical step,”says Phaedon Avouris,a member of the group that created the circuit.

1.建立一个晶体管是创建一个三明治不同掺杂半导体层.两个最常见的类型的电晶体,bipolar-junction BJT晶体管()和场效应晶体管(FET办不到)是schematically图2.1.This图显示了两种元素硅结构及其图形符号化表达可以看到在电路图.显示的是一个NPN晶体管BJT,因为它是由一个三明治的N-P-N掺杂硅.当一个小电流注入到基地,较大的电流终端能够流从收集到的国家.显示的是一个N-channel FET办不到的行车,这是由两个n型地区被p型板上.当一个电压到绝缘门终端,使电流流动的排水的来源.它被称为N-channel,因为一个N-channel栅源极电压归纳在基质,使电流流动N-regions之间.
2.这类型的模拟电路适合取决于类型的电路和你准备怎样身体实施.例如,模拟、数字和混合的模拟/数字电路PCB是建立,一般情况下,最好与SPICE仿真模拟.数字电路实施在可编程逻辑器件通常是在行为模拟语言水平,尤其常见的是和硬件描述语言(VHDL)或Verilog HDL.详细资料请看附的证明文件HDLs或你的硬件描述语言(VHDL)或Verilog产品形态电子工作台.对于非常复杂的数字设备,SPICE模型通常是不实际.在这些情况下,硬件描述语言(VHDL)或Verilog是最好的解决方案,为模拟这些设备.然后他们便可以被纳入为系统级设计方法的一部分,创造一个符号表示和使用原理HDL编码仿真模型.详细资料请看附的证明文件HDLs或你的硬件描述语言(VHDL)或Verilog产品从电子工作台.
3.即使是最乐观的硅基半导体研究者说电脑芯片只有15年左右离开了.在那之后,就不可能适合任何电路晶片越来越小,晶片上这些力量无情的计算机也越来越小,越来越智能化.因此,研究人员正在决心想出如何使复杂的微处理器从其他材料.IBM做了一个重大突破,可能在八月,物理学家托马斯·J.该公司托马斯·沃森研究中心的物理学家造出全世界第一的逻辑电路(一个长长的碳分子奈米管.虽然第一的笔记型电脑与纳米管内部仍有很长的路要走,IBM的发明”是一个关键的一步,”说,Phaedon Avouris团队的成员,创造了这条赛道.

a,b,c,b,c,a,
1、这种电晶体的两个优点就是尺寸很小和相互之间能够放得很近而不会产生温度过的问题,without是介词,后跟动词要跟动名词形式,这里是被动(被加热)所以用动名词的被动形式.
2、比较句中,第二个比较对象,常承前替代.这句可以说成:This furniture is different from that furniture.为了不重复所以用 one代替.
3、enough 用在名词前,形容词,副词后,后跟动词不定式.如:
We have enough money to buy the TV.
The boy is old enough to go to school
4.find sth done发现.被怎么样了,是固定结构,转换成被动结构就是:sth be found done."一袋玉米被发现被人偷掉了"
5、本句中,much是“得多”的意思,用来修饰比较级形式,相类似的还有still,even,a lot,a great deal.
6.it用为形式宾语,后面的动词不定式作真正的宾语.
句型:主语+谓语+it+名词/形容词+to do.
more 是much/many的比较级,much more 是“多得多”的意思,常规下,much后跟不可数,many后跟可数,不存在什么具体的情况.
如:I have many books 我有很多书.
He has much more books than me 他的书比我的多得多.
