Description
Technical field
The invention belongs to manufacturing technology fields more particularly to a kind of substitute boa skin of folk music instrument and preparation method thereof.
Background technology
Currently, the prior art commonly used in the trade is such：
In Chinese Musical Instruments, " epithelium " musical instrument is developed with its unique tone color and style in national music and musical instrument
In occupy important position.Such as trichord, urheen, high Hu, middle Hu, arena qin, pendant Hu ... etc..Now with human progress and society's text
Bright development, protecting ecology balance have become whole world problem of interest, and " boa " has been set to China's first class of protection Move objects, in
Musical instrument NEWS FROM ASSOCIATION portion of state 2003 just has 32766 in the incomplete statistics in the whole nation when being only urheen production in the 1 year Expendable boa skins that disappear
Item.Since natural boa skin is the main raw material(s) of epithelium musical instrument, this occupancy (even destroying) to natural resources is
Cause people's great attention and worry.On the other hand and caused by the source of goods that the control used raw material generates is in short supply
Rise in price, limit the production of this kind of national musical instruments normal quantity, especially trichord, its requirement to boa cortex amount is very
Height, Hen Nan Buy to the good boa skin for doing trichord, this fundamentally constrains the succession and development of national music culture.In west
Square developed country, alternative skin have formed a kind of trend, and such as timpani, the army's drum in American-European Western band, Japanese Shamisen is all
The alternative leathercraft of comparative maturity is formed.Therefore, it is necessary to increase the dynamics of this research, keep cultural continuity not environmentally friendly with the world
Trend clashes, be finally reached it is artistic with it is natural it is harmonious with uniformly.
Currently, many national musical instruments manufacture skills are extremely complex, this may is that the graceful wide reason of its vocal music.In addition to
Handicraft also needs to special material.Boa skin must be used, is not plastic pigment artificial leather, snakeskin is all not all right.Folk artisan is very long
Music practice in realize, the sympathetic response of boa skin and tamber effect are most sticks.So all using boa skin from ancient times to the present.But due to
The rise of environmentally protective idea in recent years, boa is put into protection animal, so boa skin is just less difficult to find, and uses boa skin
It is unfavorable for saving the wild animals, maintains the balance of the ecosystem.
In conclusion problem of the existing technology is：
Due to the rise of environmentally protective idea in recent years, boa is put into protection animal, so boa skin is just less difficult to find,
And it is unfavorable for saving the wild animals using boa skin, maintains the balance of the ecosystem.

When the load capacity of the first continuous work task, which is more than maximum, to handle load capacity, by one of first continuous work task
First task of overload part removes the first continuous work task；
When receiving the first continuous work task, central processing module is switched into an operation mode by a suspend mode, with
And the first continuous work task of processing；And after the completion of the processing of the first continuous work task, central processing module is set as stopping
Sleep mode；
The operating frequency of central processing module has a normal operating frequency under general operation, further includes：
One first operating frequency is determined according to the load capacity of the first continuous work task and temperature threshold value；
And when central processing module switches to operation mode, by the operating frequency of central processing module by normal operating frequency
It is promoted to the first operating frequency, and the first continuous work task is handled by the first operating frequency；
Wherein the working frequency of the first operating frequency is higher than the working frequency of normal operating frequency；
After the processing of the first continuous work task is completed and central processing module enters suspend mode, according to collecting platform power
First task of multiple second tasks and part of overloading is combined into one second continuous work task by administrative skill；
When receiving the second continuous work task, central processing module is switched into operation mode by suspend mode；
The operating frequency of central processing module is promoted to one second operating frequency by normal operating frequency, passes through the second operation frequency
Rate handles the second continuous work task；And after the completion of the processing of the second continuous work task, central processing module is set as stopping
Sleep mode；
Wherein the working frequency of the first operating frequency is higher than the working frequency of normal operating frequency；
First continuous work task is handled the time point completed and starts to receive by central processing module using the first operating frequency
To having for one first interval time between the time point of the second continuous work task, and use normal frequency by the first continuous work
Task processing had for one second interval time between completing and receiving the second continuous work task, wherein the first interval time is small
In the second interval time.
