There is a car from Phoenix transportation center to Futian port
In my opinion, this is the most similar to yours. Yours is polished. This is called pegmatite. Pegmatite is a kind of coarse-grained or massive rock mass which is closely related to various types of plutonic rocks in Genesis
power mole has been applied to all aspects of our life, modern electronic procts are basically useful to the power mole, so since it is practical, there will certainly be some problems, let's introce the factors of excessive noise in the power mole and the solutions
for the power mode, the main parameters of the output are abnormal - the output ripple noise is too large. There is no doubt that noise is a whole important index value to consider the quality of power supply mole. In the use of power supply circuit, the reasonable layout of control mole design concept will also harm the inced noise. So what are the factors that lead to excessive inced ripple noise
The distance between the power mole and the noise sensitive element of the main power circuit is too close There is no decoupling capacitor at the input end of the switching power supply of the noise sensitive element in the main power supply circuit In the multi-channel operating system, the interference of differential frequency is caused in the middle of each single output power mole The treatment of grounding wire is not scientificfor this kind of problem, it can be improved according to the plan of separating the control mole from the noise components or applying the decoupling capacitor in the main power circuit, as follows:
1
2. The input terminal of the main power circuit noise sensitive components (such as a / D, D / A or MCU) is connected with 0.1 μ F decoupling capacitor
A multi-channel derived power supply mole is used to replace several single output moles to eliminate the differential frequency interference The total area of the ground wire loop should be recedHandling items: identification of work-related injury (work-related death)

This is granite. Granite is a kind of igneous rock formed by magma condensing below the earth's surface, mainly composed of feldspar and quartz. It is an acidic intrusive rock composed of potash feldspar, quartz and plagioclase. It has a subhedral granular structure or porphyry like structure and massive structure. It often occurs as a rock stock and batholith. The related minerals include rare metal and radioactive element deposits< br />

the judgment is very simple:
1. Press and hold the video card and CPU fan separately by hand, and do not let it rotate. Pressing and holding the fan to rece the noise is the problem of the fan
2. If both fans have no effect on the noise, it is estimated that it is the noise of the power supply fan. Make an insulated wood chip and block the fan in the power supply hole to see the noise change
determine which fan has the problem and replace it.
