帮我翻译成英文,谢谢!

你好!

hello!

想要更多的了解你,

I'd like to get to know you alittle more.

你一个人住?

Do you live alone?

父母呢?

How about your parents?

有兄弟姐妹吗?

Do you have any siblings?

一直没有结婚吗?

Are you single?

可以的话你发其他照片给我.

Send some of your photos to me if you feel like it.

我们昨天下了入冬以来第一场雪,不大，但我仍然很兴奋.

Yesterday we saw the first snowfall this winter. it's light, but still I'm so exited.

我的外表和内心世界比我的实际年龄要小的多,很年轻充满活力,

I'm really energetic,and my mental age and appearance is way younger than my actual age.

你工作很忙吗?

Are you busy at work?

你们那现在是几点钟?

What time is it at your place?

是晚上吧?

it's night, isn't it?

我们这儿现在是上午9点.

Well, it's 9 o'clock here.

是希望一天的开始.

The time when dreams are awake and hopes begin.

Hello! I want to know more of you, are you live alone? Have you brothers or sisters? Haven't you get married yet? If possible,you can send some pictures to me, yesterday we saw the the first snowfall this winter, although it is not so heavy, I felt excited,I am younger than what I am in appearance and heart, and I am full of energy, are you busy with your work now? When it is now in your place? is it night time? Here is 9 o'clock in the morning, and it is the beginning of one hopeful day.

Hello!Many wants to understand you, you live? Parents? Has brothersthe sisters? Always does not have the marriage? May the speech yousend other pictures to give me Since we had yesterday gotten down thebeginning of winter the first snow, is not big, but I very was stillexcited My semblance and the innermost feelings world want small manycompared to mine physical age, very young is full of the energy, youwork very busily? How many o'clock is your that present? Is theevening? Our present is morning 9 o'clock Is hopes a day-long start

5, RS-422 and RS-485 transmission lines that match the description of some

The RS-422 and RS-485 bus network in general resistance to the use of terminating match. But in the short distance and low rates can not consider the terminal match. So under what circumstances do not have to consider matching it » In theory, each receive data signals in the mid-point of sampling, as long as the signal reflection at the beginning of sampling at the low enough to decay can not consider the match. But in practice difficult to grasp, the United States MAXIM companies have an empirical articles referred to the principle can be used to determine what kind of data rate and cable length of time needed to match: When the signal conversion time (rise or fall time) Electrical signals along the bus more than a one-way transmission time for more than three times when it can not match. For example, has limited the slope of the RS-485 interface MAX483 output increase or decrease the minimum time for the 250 ns, typical twisted pair on the signal transmission rate of about 0.2 m / ns (24AWG PVC cable), then as long as the data rate of 250 kb in / s within the length of cable is not more than 16 meters, MAX483 used as a RS-485 interface at the terminal can not match.

General terminal match by terminating resistance methods, Qian Wenyi mentioned, RS-422 bus lines in the remote access and resistance, RS-485 bus lines should be in the beginning and end are subject to termination and resistance. Termination of the resistance in general RS-422 network from 100Ω, in the RS-485 network from 120 Ω. Impedance of the cable equivalent of resistance, because most twisted pair cables impedance of about 100~120 Ω. This matching method is simple and effective, but there is a drawback, matching resistance to high power consumption, more stringent restrictions on the power system is not suitable.

In addition a more efficient way of matching the RC match. Use of a capacitor C cut off most of DC components can save power. However, the value of capacitance C is a difficult, power consumption and the need to match the quality of a compromise between.

There is also a diode using the matching method. Such programmes not yet a real "match", but its use diode clamp role of the rapid weakening reflection signal to improve signal quality. Energy-saving significantly.
