If the development of science and technology is very strong, it should be able to predict the future
The application of 
computer is more and more common in China. After the reform and opening up, the number of computer users in China is rising and the application level is improving, especially in the fields of Internet, communication, multimedia and so on. From 1996 to 2009, the number of computer users increased from 6.3 million to 67.1 million, and the number of networked computers increased from 29000 to 59.4 million. Internet users have reached 316 million, wireless Internet has 670 million mobile users, including 117 million mobile Internet users, ranking the first in the world
2. The bandwidth of the control system generally refers to the frequency when the amplitude frequency characteristic curve in the Bode diagram of the closed-loop system drops to - 3 dB. Note that this is the amplitude frequency characteristic of the closed-loop system, not the amplitude frequency characteristic of the open-loop system for stability analysis. The bandwidth of the control system is mainly determined by the zeros and poles of its closed-loop transfer function, which reflects that when the reference signal is higher than this frequency, the system will not be able to track with normal amplitude, so the larger the bandwidth is, the faster the frequency the system can respond to.

The meaning and ideological connotation of Turing machine: Turing did not propose the model of Turing machine to give the design of computer at the same time. I think it has the following significance:
1. It proves the general computing theory, affirms the possibility of computer implementation, and gives the main architecture of computer
The Turing machine model introces the concepts of reading and writing, algorithm and programming language, which greatly breaks through the past design concept of computing machine The theory of Turing machine model is the core theory of computing science, because the ultimate computing power of computer is the computing power of general Turing machine, many problems can be converted to the simple model of Turing machine
extended data:
"Turing machine" is just a fake "computer", it does not consider the hardware state at all, and the focus is the logical structure
In his works, Turing further designed a model called "universal Turing machine", which can simulate the working state of any other "Turing machine" solving a specific mathematical problem Turing even imagined storing data and programs on tapes“ "Universal Turing machine" is actually the most primitive model of modern general-purpose computer4. Hello, your problem, I seem to have encountered before, the following is my original solution ideas and methods, hope to help you, if there is a mistake, please forgive me! 1. Geographic information detection: through computing power, 3D modeling method is established to detect and identify buried underground materials, which can detect, identify and mark multiple types of main underground information more quickly, comprehensively and accurately, rece the occurrence of miscarriage of justice in manual data analysis, and improve the accuracy. For example, the detection of urban underground water pipes, wires and so on
2. Weather prediction: more weather models can be simulated, more parameters can be analyzed, and more accurate and farther future information can be predicted through calculation power
3. Special effects rendering: concentrated super computing power can rece the time of movie rendering and improve the rendering efficiency. In addition, there are more big data, AI related video, medical image analysis, agricultural remote sensing, environmental monitoring and other instries can be applied to
I found all of them on the Internet. It's very hard. I hope you can adopt them. Thank you. Thank you very much for your patience. If you have any help, please accept it. I wish you a happy life! thank you!

5. The internal memory is the place where the instructions and data are stored when the computer is running. No computing power
the computing power lies in the arithmetic logic unit (ALU) of CPU.

6. The reasons for the poor calculation ability of class 2 students in Grade 5
through the analysis and Research on the types and causes of errors in written calculation of students in different grades in our school,
can correct the errors in written calculation of students,
but e to the differences in cognitive development level and existing knowledge and experience of students,
written calculation errors are also different< According to the collected survey materials,
students' written calculation errors can be roughly divided into two categories: knowledge errors and non knowledge errors
knowledge errors refer to the errors caused by students' incomprehension of
rules, calculation principles, concepts and operation order of pen algorithm, or their failure to master the learned knowledge
non knowledge errors refer to the errors caused by students' bad study habits. We can't help asking:
"
rough
careless
"
what is the reason<
through the investigation and Research on students' computing ability,
carefully analyzes the causes of students' computing errors< The results show that there are many reasons for students' miscalculation, and the main reason is that students have various mental obstacles in calculation<
first, the perception is rough
when students calculate, they perceive things more general,
rough,
often perceive similar data or symbols
distortion, resulting in errors<
Second, fixed thinking method
fixed thinking method has both positive and negative effects in calculation. When students master a certain calculation method, they tend to use similar old methods to think about problems,
this will inevitably lead to laziness of thinking,
affect the speed of calculation< At the same time, e to the repeated practice of a certain type of exercises,
make students first
into the main, middle school students often use the habitual method to solve completely different problems, thus making mistakes<
Third, memory restoration
in the process of storing information,
e to the influence of time,
amount of review and many other factors,
makes the stored
information disappear or interrupt, resulting in

subtraction, multiplication and division, the amount of instant memory is large. In addition, the simplification of

in terms of operation form,
students' calculation is from perception to representation and then to abstract< From the perspective of thinking characteristics of primary school students,
their thinking is specific and imaginative,
imagery often becomes the basis of their thinking< 5. Strong information interference
students' audio-visual perception is selective,
the degree of information they receive affects their thinking
when calculating, some strong information is easy to come to the eye and cover up other information<

thoughts; Second, when the number is large and the calculation is complex, impatience and boredom appear. As a result, they often have bad habits such as writing in a hurry before they can see clearly, and not checking after they have finished< There are many ways to solve problems, which requires us to be good at choosing the best
the students with poor computational ability are obviously lack of comparative consciousness,
lack of consciousness of strategy evaluation,
when doing questions, they often find a way to do it, even if it is cumbersome, they don't care. They are satisfied if they think it is right, and seldom consider whether there are other good methods?
