Q:Imitation copper paint are sunscreen it?

First, metal copper ????- element symbol Cu, atomic weight 63.54, specific gravity 8.92, large capacity 1083 °. ????- pure copper was light rose or light red, the surface of the formation of copper oxide film, the appearance of copper. Copper physical and chemical properties: good thermal conductivity and conductivity, chemical stability, tensile strength, easy to weld, with corrosion resistance, plasticity, ductility and so on. - The appearance of copper is red, and it is also recognized as a green metal (durable, recyclable and re-use and copper elements are animal and plant and human health, survival indispensable trace elements). ????- Copper is one of the ancient metals used by mankind. Has now been widely used in electrical appliances, light industry, machinery, construction, defense and other fields, and into the modern living space, copper doors, windows, handicrafts, roofs, awnings, lamps and so on. , ????- Copper products because of its deep artistic and cultural heritage, environmental protection, corrosion resistance, durability, antibacterial, applicability, etc. can be widely used. As the new copper door, window product, it is widely used in financial system, hotel hotel, business, clubhouse, office area and high-end villa, district and so on.

Q:Shooting studio products need some props, in addition to lighting. To answer specific, it is best to have a program

Decorations need to think that the product to match the variety I can not tell you to the LZ some more practical props it line fine wire (shooting jewelry jewelry jewelry and the like can often use) soft light aluminum paper filter paper alcohol (stainless steel kitchenware products Can be used) foam adhesive tape (electronic products can be used) iron bucket hair dryer (clothing can be used)

Q:Can the armor be combined with PF?

The success of the property of the door armor to strengthen the probability of success with the same thing is the same, the failure will disappear directly There is a property of the armor is that you have the property of the PF and the white door of the synthesis of the synthesis of PF there is no if the reinforce the failure that the door will not have a careful recommendation to buy finished door armor

Q:In the doors and windows project is the door to open the door but the door has a sliding window of this combination of doors is what the door

The combination of open doors and sliding windows. To ask what is called, it is called flat open the door.

Q:What is a sequential circuit?

Timing logic circuit is called timing circuit Timing circuit, which is composed of the most basic logic gate circuit with feedback logic loop (output to input) or device combination of the circuit, and the combination of the most essential difference is that the circuit has a memory function. Sequential circuit is characterized by: The output depends not only on the input value at the time, but also on the state of the circuit in the past.It is similar to the circuit of the inductor or capacitor containing the energy storage element, such as flip-flops, latches, counters, shift registers, Are typical devices of timing circuits.

Q:Three-state output circuit is what does not mean to understand

Three-state gate, tri-state circuit is an important bus interface circuit. The tri-state here means that its output can be either a normal "0" state and a "1" state of the general binary logic circuit, and can maintain a unique high-impedance state, a third state - a high-impedance state Gate circuit (high impedance state is equivalent to cut off state). In the high impedance state, its output is equivalent to the open state, there is no logic control function. The output logic state of the tri-state circuit is controlled by an input pin. When G is low input, the tri-state circuit exhibits a normal "0" or "1" output; when G is high, the tri-state circuit gives a high-impedance output.

Q:Twice the top of the portfolio

Facade is Mina, child yu is the highest yu yu

Q:Just bought a suite, do not know how to choose the door, we give some advice, thank you friends

You can do the door of the louvers, hanging door, cut off the door, etc., it is said that Roland home over there are many types of items, you can go and see

Q:Who knows the door of a good lady? I want to do regional agents

China's top ten brands of solid wood doors, from the classic brand in Italy, Jiangsu Province to promote the major brands, the national high-tech doors 30 companies)

Q:There is no experience of the master to say a little way to increase it Thank you To the end of the auxiliary Jiuyou disk and the Temple can not force the main want to know how this combination of the team is their own nothing to play do not seek too high-end can mix a point card money like

Output is very slow, especially in the 105 before, the output is very laborious, especially the higher the level, the greater the gap, the traditional attack system to the late than your force disk, force Temple, Do not know how much output to be higher, unless you want to play 69, then forget it.
