Abstract It is generally well known that controlling temperature accurately and with fast process response times presents practical difficulties to standard programmable logic controllers. The root cause of this is that before the constantly changing analog signals from thermocouples or resistance thermometers can be processed digitally, an analog-to-digital conversion process is necessary, often resulting in loss of overall accuracy and measurable time delays. Here, details on how to control temperature accurately in programmable logic controller-based systems are presented.

those above is Fukang translated, anybody would like to advise pls write down yours.[em09][em09]

I was willing to try, but was later prevented from it when I found the Chinese version of the abstract itself was quite confusing. What does the follows mean?

众所周知准确地控制温度和与快速的处理实际的问题使用标准可编程序逻辑控制器。

太湖之梦

As is well known, standard programmable logic controller is often applied on accurately temperature controlling and fast processing practical problem. The origin of this may be the analog signals for the thermocouple or that of resisting thermometer changing, and to the digital signals to deal with, an analog-to-digital conversion process is necessary, which often results in the loss of overall accuracy and measure time delay. Here, details on how to control temperature accurately in programmable logic controller-based systems are presented.

i think the first setence should be “众所周知准确地控制温度和快速的处理实际的问题 使用 标准可编程序逻辑控制器” .

My major is  not the Automatics, so my translation is depend on my little knowledge about PLC and the primary content.

Based on the previous two translations, I proposed my trial one as follows. BTW, the logic of the original words is/seems not so reasonable.

It is well-known that standard programmable logic controllers are often applied to accurate controlling of temperature and rapid processing of practical problems. This is probably due to that there may exist a constant loss of overall accuracy and delay of measurement time, which is caused by the analog-to-digital conversion procedure if there is a need of processing digital signals when we acquire the changed analog signals from thermocouples or resistance thermometers. We present here on how to accurately control temperature in the systems based on programmable logic controllers.

众所周知,标准可编程序逻辑控制器使用于，准确地控制温度和与快速的处理实际的问题。 它的起因是可能经常从热电偶或抵抗温度计改变的模拟信号，而需要处理数字信号, 一个数模转换过程是必要的, 经常造成全面准确性和测量时间延误的损失。 这里, 细节提出关于怎样在基于可编程序逻辑控制器的系统来准确的控制温度。

以下是引用SgBoy在2005-6-10 21:06:29的发言：

Some further modifications as above.

In particular, the first sentence is revised according to the author's own translation:

"controlling temperature accurately .... presents practical difficulties to standard programmable logic controllers"

Thanks every body ,I'm very excited there are so many peopel talk the topic with me .I'm machenic student in kunming .it is English traslation to chinese,but it's my miss put the chinese first .
