The quality of Nokia and Moto is good and recognized! In China's mobile phone sales list for several years, the top two are his 2, Lenovo is the third, the fourth Suo Ai, the fifth, and the bird

So, in your requirements, it should be m or n.

The keyboard and the shaft of v3 are not very good.

6170 then heard!

See for yourself before you buy.

He's talking about two models of Motorola, ultra-thin, V3i ***, but there are more people who use it.

You specified whether it was v3, v3i, v3 that was poor, or that v3i, an upgraded version of v3, was better

1.It's not that it's unattainable, it's technical considerations. The resolution is large, and the power consumption is also large, and each terminal has its own positioning.

And now it's not just the iPhone is 960*640, Meizu M9 is just a small screen, both support multi-touch technology and are audio-visual entertainment machines (large requirements for screen resolution and coloring), it is a waste for business machines to use such a high resolution. At the same time, high resolution without good display core support is also in vain. 2.

In fact, mobile phones also have "graphics cards", generally called display cores, which are integrated with the CPU, the mobile phone space is small, and the heat dissipation effect is not ideal, so the above high-frequency CPU mobile phones can't stand it, just like Xia uses the V8 engine to move. The phone doesn't need to run large software yet, so the CPU at this stage is enough and won't cause overperformance. 3.

The small battery capacity of the mobile phone is that the new mile battery has not yet been mass-produced, and the technology is still immature, and the second battery capacity is also dangerous, and the voltage or current is too high when used to cause the mobile phone to crash and collapse. In addition, the current charging input is generally 150 to 350 mAh, and the input can reach more than 500 mAh when charging domestic large-capacity batteries. The capacity is larger, and the input has to be stretched upwards like a bomb.

If you are not careful, something within 5 square meters will be injured. The capacity is also large, so you can't use Big Brother.

Hello landlord! 1.The problem with screen resolution is not that it is not up to it, nor is it limited by anything. It's that the high resolution is too expensive.

2。The phone also has a CPUBut I don't know much about the problem of the phone's graphics card.

3。Battery I am the most professional. The domestic battery is written 1200-2500 mAh or something. There are even 10,000 mAh. Am I dizzy? It's all fake. Generally 450-850 mAh.

I think about it so much, and I can see that I pay attention to this aspect.

In any case, the package is 126 cubic centimeters in volume.

The structure of nitrate ions is explained clearly by resonance.

If you think about it from the perspective of a large bond, that is, 3 bonds, 1 four-center, six-electron major bond, if you consider it from the perspective of a classical covalent bond, there is a coordination bond.

Major key, coordination key. These are different theories, don't mix them up.

First of all, bai, hybridization.

It is the hybridization of the central atom, and the nitrate is separated from the nitrogen atom in the son.

The central atom, nitrogen hybridized dao, oxygen is not the central version of the atom, and the weight oxygen atom is not hybridized. The hybridization theory is mainly proposed to explain the molecular structure.

The nitrogen atom adopts sp2 hybridization, that is, 1 electron in the 2s orbital is excited to the 2p orbital first, so that the 2s orbital has 1 electron, 3 2p orbitals of which two of each have 1 electron, and 1 has 2 electrons, and then, the 2s orbital has two 2p orbitals with 1 electron and mixes to form 3 identical sp2 hybrid orbitals. Note that hybrid orbitals can only be used to form bonds and accommodate lone electron pairs.

The nitrogen atom forms 3 bonds with the three oxygen atoms through the 3 sp2 hybrid orbitals, and there are 2 electrons in the unhybridized 2p orbital of the nitrogen atom, and this 2p orbital is perpendicular to the plane formed by the three hybrid orbitals. The three oxygen atoms donate three electrons in their 2p orbitals, plus the one obtained by the nitrate ion, for a total of 6 electrons, forming a delocalized bond of 4 atoms and 6 electrons.

The oxygen atom does not need to be hybridized, and its 3 orbitals perpendicular to each other of 2p have one filled with 2 electrons, and 2 have 2 orbitals filled with 1 electron and 2 electrons respectively, one of which is used to form a bond with the hybrid orbital of nitrogen and one is used to form a large bond.
