Please give me a recommendation and analysis of the machine

Keyboard: Writing text and texting is quite cool, the key is to see the input method support. But DoPod doesn't seem to be very easy to use, I use HP6515's QWERTY keyboard is quite good and the same input as PC, but the model is quite old, WM2003 system.

The weight is also quite large. However, the Qwerty keyboard is among the best in terms of weight and volume.

2.The operation is stable and bug-free, or it is better to buy licensed goods, but unfortunately there is not much silver. In order to get a better model, you can only buy parallel goods, but the ROMs of parallel imports are all brushed by the supplier themselves, and there will definitely be bugs.

The keyboard is indeed a chicken rib, is it in order to send text messages faster (now plum blossoms, sogou are not necessarily slow) every day with half a brick in the pocket?

4.The BlackBerry is very good, although there is less software support. But there are still necessary ones. For example, QQ, e-books or something. There are fewer games.

Caesar. The system is all stable.

The CPU of PPC should definitely be above 400...

Anyway, BlackBerry's 9000 is not a PPC system.

The BlackBerry system is outdated. There is too little software.

Let's use the PPC system!! That's the way to go.

Hehe, parallel diamond pro (touch diamond pro) we sell 3200, very good! You're so rich ... I bought a diamond (non-pro) and it cost 2600

Precautions? I feel like you'd better go to a specialty store (there are also parallel goods), it's better not to go to the parallel market, I've seen a lot of people buy second-hand, refurbished, and it will be very depressing. If you go to a specialty store, you can spend an extra 100 or 200 for peace of mind.

When you buy it, you take a look at the call history (although you can also brush it off, but take a look).

Anyway, we rarely buy second-hand in Harbin, refurbished...

On your terms, Touch Pro is preferred, followed by P4550. Personal use feeling, PPC's full keyboard is very chicken.

**Not safe,Always take the cottage to fool people,It is recommended to buy it in a physical parallel store,I have a lot of such stores here,In addition, it is best not to buy a full keyboard to buy ppc,You can't use the keyboard at all,And the fuselage has increased,Buy diamond 2,Parallel import** is 3400.The ** of the generation is 2300

Diamond! Or pro, more perfect!

**There are also good merchants. It's not that every business is not good. The key is whether you find a good merchant or not.

We're all ** making mobile phones. Parallel imports are generally produced in European countries. Parallel imports***.

The quality of parallel goods is better than that of the mainland and Taiwan versions. Why do you say that, the technology of foreign production and the manufacturing of all parties are relatively good.

Dopod is like this with a lot of machines. Side-sliding keyboard,I use Dopod CHT9000,It's very handy for a year and I haven't found any problems.,You can take a look.。

If you are selling lubricating oil, I recommend you to write a "Lubricating Oil Selection Manual" written by Wang Xianhui and Wang Guangyin, which has very detailed content for various lubricating oil applications in various working conditions.

Since it is a sales of lubricating oil, we must first understand our own products, if the characteristics of each model of lubricating oil are clear, what equipment the product is used in will naturally be clear.

Hehe, it must have been very confusing at first, because our industry basically involves all industries. Therefore, the most primitive way is to start with small customers, run hard to customers, accumulate knowledge from practice, and let some recent knowledge still need to be understood.

There are many types of lubricating oils, and the lubricating oils used in different machinery are different, and the lubricating oils used in different mechanical oils are specified by themselves.

There are ordinary lubricating oils, special lubricating oils, assembly greases, etc., Guangzhou Lianbo lubricating oil is good can be recommended.

Solution (1) from the title, 70 (1-60%) = 70 40% = 28 (kg) (2) set up workshop B to process a large mechanical equipment lubrication oil for kilograms, from the title, get [

(x-75) (x+10)=0

Solution: x1 = 75, x2 = -10 (rounded).

This question will not be, but I will answer question 8!

Let the width of the path x32 20-2 20x-32x+2x =570x -36x+35=0

x = 1 x = 35 (rounded).

Give me an answer, adopt me!

Give me an answer, adopt me!

Give me an answer, adopt me!

Give me an answer, adopt me!

Give me an answer, adopt me!

You can go. Shanghai to find some, for example, Luo Ge De Runbao, Total and other internationally renowned enterprises, the same quality is also quite good. At present, there are many sales outlets in China, which you should be able to find in your local area.

Don't trust some brand names with international names. Right now.

I haven't noticed, I've been using it pretty well. But what is certain is that it must not be the fault of your phone. It's the software itself. It seems that when the mobile phone is invisible, the computer can see it.

All moving machinery requires lubricating oil and grease. The longest lubricating oil used in machinery manufacturing enterprises are: hydraulic oil, gear oil, cutting oil, general grease, etc. Break a leg. For details, please consult Shanghai Ruibei Petrochemical****.

All machines are lubricated. It's just that the lubrication environment is different, and the type of lubricating oil is also different, which is difficult to explain very clearly. To put it simply, the simplest machinery like a joint also needs to be lubricated.

As long as it is an enterprise, lubricating oil should be used. Even a door lock is used.

Lubricating oil is often used in transmission machinery, and it is used in manufacturing industries such as automobiles and motorcycles.

There is a distinction between automobile oil and machine oil, and the car is more precise.

Lubricating oil (commonly known as engine oil) is divided into automotive lubricants and industrial lubricants!!

The lubricating oil is suitable for use in high-temperature, high-speed, heavy-load, and harsh environments, so as to add graphite or metal additives to better meet the needs of the lubrication grade and minimize all kinds of friction!!

Industrial lubricants do not require a high viscosity index of the lubricating oil, and no additives are added!! Therefore, the general lubricating oil of the machine cannot replace the special lubricating oil of the automobile!! Lead is resistant to locust.
