The outstanding functions of this multi-fucntional wheelchair is that the hight of the seat could be adjusted at will. So that it may stretch users' operating space and make up users' physical handicap.It could alleviate the workload of paramedics as well. It is more advanced than previous products.This wheelchair could be driven by hand or electricity. Thus, the shortage of physical force of old and handicapped people could be solved. At the same time, users could still operate this wheelchair when batteries run out. Such design eliminate worries of users on a long-distance trip.In addition, a super big storage box on tail of wheelchair brings great convenience to users. backrest can be adjusted multi-anglely. Adjusted feet board increases cosiness. A small table of this wheelchair really brings extraordinary convenience when users want to read, write or do other activities.

本设计的多功能轮椅最突出的一个功能就是座位的高度可以根据使用者的需求随意进行调节，这样就可以大大扩展使用者的操作空间，补充了使用者在身体上的缺陷，也可以减轻照顾人员的工作负担，比起以前的产品有了较明显的改进；其他功能还有轮椅的手动电动两种驱动方式，这样可以解决老年人和残疾人在体力上存在的问题，同时在外出时遇上没电的情况也不至于显得无能无力，消除了使使用者在长途奔波时的顾虑；此外位于轮椅尾部的超大储物筐，给使用者携带物品带来了极大的方便，靠背的多角度调节，脚踏板的高度调节大大增加了使用者的使用舒适度，轮椅上小桌的设计给使用者读书，写字，进行其他活动带来了极大的方便。

Applied to automotive engineering, the boxfish is therefore an ideal example of rigidity and aerodynamics.

应用于汽车工程学， boxfish 堪称硬度和空气动力驱动方面的典范。

For applications to be fully Internet-enabled, Oracle, PeopleSoft, and Dun and Bradstreet will have to reconstruct their wares and rewrite not only the client, but also the server portion of their applications in Java or ActiveX to improve security.

对于完全由internet驱动的应用程序，oracle、peoplesoft和邓白氏公司将必须重构他们的软件，不仅要用java或activex重写应用程序的客户机部分，还要重写服务器部分，以提高安全性。

To acquire data in your lab using the virtual instrumentation approach, you will need a DAQ device, a computer configured with LabVIEW and DAQ driver software, and some method of connecting your transducer signal to the DAQ device, such as a connector block, breadboard, cable, or wire.

在实验室中使用虚拟仪器来获得数据，你将需要一个DAQ装置，一个配置了labview和DAQ驱动软件的电脑，和将你的传感器信号连接到DAQ装置的方法，比如一个连接块，面包板，电缆或电线。

This topic returns in view of the cut type switch spreads the type switch "to return for the predecessor design spreads the type electric power switch utilization in the LED lamps and lanterns" is the research direction, to achieve take reduces the power loss to replace the tradition operational amplifier pulse wave width accent as the goal using IC UC3842 changes part, the actuation returns spreads the type electric power switch's switch of Power MOSFET, so as to controls instead spreads the type electric power switch breakover closure's time then control voltage output size, achieves the output voltage to the load LED lamps and lanterns adjusts the LED lamps and lanterns brightness the goal.

各位大大抱歉~！因为英文底子不好！希望大家帮忙翻译一下，希望不要用翻译软体翻的最好是自己翻！拜托了！本专题针对切换式转换器的返驰式转换器为前身设计「返驰式电力转换器运用在LED灯具」为研究方向，为达到以减少功率损失为目的利用IC UC3842代替传统运算放大器脉波宽度调变部分，驱动返驰式电力转换器的Power MOSFET之开关，藉以控制反驰式电力转换器导通截止的时间进而控制电压输出的大小，输出电压至负载LED灯具达成调节LED灯具亮度的目的。

The principle is using thefast breakover of avalanche transistor drive the electron tube. The full time of 4200Vvoltage is about 20ns. The circuit can normally work under 100kHz frequencies.Design an extra fast Q-switch circuit by series arrangement of avalanche transistor.
