. $$ (+ x) \cdot \frac{7}{10} = \times \frac{3}{5} + x$$ $$\rightarrow x = \frac{200}{3}.$$ so should be added copper $\d frac{200}{3}$ G.4. Hard aluminum is $4\%$ copper, $1\%$ manganese, $0.5\%$ magnesium and $94.5\%$ aluminum preparation, melting loss rate according to $1.5\%$ calculation. Manufacturing $250$ kg hard aluminum, how many kilograms of the above m

increased, the signal will fade quickly. In fact, compared with Wi-Fi radiation, mobile phones have a greater impact on human body. Because mobile phones are usually very close to the brain, on the contrary, Wi-Fi can be used without having to attach a vro. It has been proved by experiments that it takes only 20 minutes to make a phone call, and the radiation absorbed by the human body is far more than the use of Wi-Fi for a year. According to the above introduction, Wi-Fi has very little impac

fire prevention, sound absorption and heat insulation requirements, aluminum perforated bone spenders are often used. The aluminum perforated bone spam roof is a lightweight aluminum shell with a hole distance and a hole diameter. The filled material has the characteristics of noise reduction and fire prevention. Iii. IDC Wall Construction The purpose of interio

seven types of cables are shielded with aluminum foil, the tension of the shielding tape in the process should be kept constant to prevent periodic fluctuations, and the change range should be less than or equal to 10%. During the shielding process, a proper mold size should be designed to make the aluminum foil fit. In order to ensure the stability of the cable transmission performance, because the

line version of the entire netcom also for users to bring greater convenience. And the new Android 5.0 system is running very smoothly, and the machine also supports turbo-charging, random with Motorola Turbo charger, charging speed very fast. One plus cell phone 2. Reference Price: 1999 RMB A plus mobile phone 2 is a new flagship mobile phone, the machine in the fuselage continuation of the previous generation

All solid-state capacitors are called solid aluminum electrolytic capacitors. It differs from the ordinary capacitance (i.e. the liquid aluminum electrolytic capacitor) with different dielectric materials, liquid aluminum capacitor dielectric material as electrolyte, and the dielectric material of all solid-state capacitors as conductive polymers. Advanta

2013 Sony Sony's existing product line can be divided into tap (Aio all-in-one machine), Duo (deformable flat/Super), Pro (flagship model), Fit (home entertainment models) four categories. The VAIO Pro combines the benefits of VAIO Z with VAIO x, VAIO Pro uses the hexagonal line design of the VAIO Z, the carbon-fibre fuselage and the aluminum alloy back cover panel, and the overall size and thickness of the VAIO X is the ultimate slim, thin, light and

, Apple began to promote Intel's core processors in all production line products. According to Apple, the core Duo processor can significantly improve the performance of imac, in addition to this, the shape design, price, function will continue to G5 design.In 2007, Apple refreshed the imac line and released imac with Core 2 Duo processors, including 17-inch, 20-inch, and 24-inch modelsIMAC (aluminum case)In the 2007 summer press conference, the

COB Black (Epoxy) is usually not allowed, because the external air hole will not only affect the appearance, the internal gas hole is more likely to break the wire bonding aluminum stability. Even when the cob process is complete, there is no functional test, it does not mean that there is no problem, because after a period of time, it is very likely because of the gas Conne hot hyperinflationary cold contraction of the role of the

, the rearview mirror can be heated by the heating wire embedded in the lens to ensure that the lens surface is clear. ●Front window induction Automatic wiper The sensor wiper can automatically adjust the running speed of the wiper through the rain sensor to provide a good vision for drivers, thus greatly improving the convenience and safety of rainy driving. ●Rear window wiper It means that the rear windshield of a car also has a wiper, which is usually assembled on an off-road vehicle and a

radiator unit is similar to that of the automobile water tank. It adopts a large-area heat sink design. The cooling fan size is 120 × 120 × 25mm, and the fan speed is between 1300 and ~ Adjustable between 2400rpm, noise between 17 dB and 21 dB. At the highest speed, 12 cm of the Heat Dissipation fan provides air volume up to 93.7cfm, while the noise is only 21dba. This ensures the heat dissipation effect while allowing you to fully enjoy the mute space it brings. The size of the heat sink is 12

and now popular use of the glass pad, as well as the expensive aluminum mouse pad, can be described as a step by step, continuous development. However, the price of the aluminum mouse pad is very expensive and not affordable by consumers. The aluminum shell of Apple air, coupled with the sand grinding surface, makes the user feel more accurate. This kind of surf

How does the charm blue metal solve the signal problem? Charm Blue metal is formed by die-casting mold + spraying paint + local CNC Three kinds of technology to create a body forming the metal. All-metal fuselage, currently physically restricted, signals difficult to penetrate all metal and cannot be made on the phone. So how does the charm Blue metal solve the problem of coexistence of metal fuselage and antennas? Here is the answer given by the Phantom. The first step: smelting Crystal Meta

of channel transmission capability, the S/FTP cable can provide higher signal-to-noise ratio (SNR) in the same bandwidth, so the s/ftp cable is an ideal solution for high-speed network applications. Anti-jamming capability of shielded cable From the index analysis of the coupling attenuation of cabling system, the ability of the twisted pair cable to resist electromagnetic interference with various kinds of cable shielding mode is increased by 20~30db. Among them:

Before the formal installation, we first introduced this set of 2015 sixth generation of new platform computer Configuration specific situation, the host configuration list as follows.

Aluminum-Magnesium alloy body solid and beautiful The Endurance for business originally said, more is the pros and cons of the balance of the intermediate products, because the endurance and weight, performance (the same generation of hardware) is often antagonistic relationship, the result can only be a compromise. In order to alleviate this contradictory relationship, many manufacturers in the form of batteries began to make a fuss, which trie

want to replace the heatsink without having to remove the entire motherboard). Similarly, the capacitance around the CPU socket should not be too close, otherwise, the installation of the radiator is inconvenient or even some large heatsink can not be installed, the second is likely to damage electrolytic capacitors. Motherboard Capacitance Selection Considerations The motherboard in the choice of capacitance is also very important, capacitance is the storage charge of the container, its role

Although many are praise, but still can not erase the value of good articles. This is the case, this is a Gizmodo article on the design of the IPAD industry, the evaluation of the very high, we do not translate this text to fully agree with its views. Apple's latest iPad is a good illustration

balance feature may be compromised. Under the ideal condition, the signal generated by the network device is completely symmetrical, but it will be destroyed by unbalanced transmission channel such as cable. This means that the impedance of the grounding line on the entire link must remain constant. It is also required that no metal object be present near the unshielded cabling system, because any piece of metal around the cable can disrupt the balance characteristics of the UTP cable and thus
