Test chart. For maintenance. Test whether the color of the broadcast signal of the TV station is normal.
In the past, this standard TV signal was often composed of color blocks, dense stripes, frames and circles, so we called it a globe map, which can be used by experienced people to adjust, identify and repair TV sets.
Basically, the TV test signal (even if it is generated by the equipment used by the TV manufacturer) is much the same.
1. Black and white rectangular border guard This is used to adjust the amplitude of line and field scanning and the center position of the image. The aspect ratio of the test chart is the same as that of a color TV screen, which is also 4:3, so it can be used to check the aspect ratio of the TV, and the vertical bezel is used to check the synchronization separation and clamping.
2. The gray background and white grid background are in the border protection frame, except for the large circle figure and the rectangular color bar signal around the circle, which are composed of the white line square pattern on the gray background. It has 13 tiles horizontally, 17 tiles vertically, and a gray background brightness of 30 for black to white, allowing it to check geometric distortion, nonlinear distortion, dynamic convergence, and color purity.
3. Circle, which is used to check geometric distortion and nonlinear distortion.
4. Signals in the circle, there are 9 kinds of test and flag signals in the large circle of the color TV test chart, which are arranged in order from top to bottom
a Television station logo, which indicates the name of the television station broadcasting.
b represents the standard skin tone of Chinese, which can be used as a reference when adjusting the hue, color saturation and brightness of the TV.
c Black and white square wave to check the transient response of the brightness channel of the TV.
d The color signal has 6 color bars below the gray band, and they are arranged in the order of yellow, cyan, green, purple, red, and blue. It gives the TV viewer a general impression of color, and uses it to adjust the hue and color saturation, and also to check whether the automatic achromatic circuit of the TV is working properly.
e White center crosshair, white center crosshair on black background, horizontal white line width 1 line, a total of 2 lines; There is 1 vertical white line in the middle, and 5 symmetrical lines on each side, a total of 11 lines. Used to determine the center position of the entire image, check interlacing, and static convergence.
f Clarity line There are 5 levels of line. It is located below the inner station logo and skin color symbol of the large circle, and it is used to observe and adjust the sharpness of the TV, the bandwidth of the color saturation part, and the locking relationship between the subcarrier and the line frequency.
g Gray scale, below the sharpness line, there is a horizontal band that gradually changes from black to white, which is a test band for measuring gray level. This test strip is divided into 6 levels according to the amplitude of the electrical signal, and the linearity and white balance can be checked and adjusted.
h The white rectangular block is used to check for high-frequency reflections due to poor antenna or cable matching, etc.
i Standard time marker, with Beijing Standard Time broadcast in a black rectangular block on a white background for the viewer to use in time.
J Color signal around the circle There is a square on each of the four corners of the outer border of the test chart, each with a certain brightness and color saturation value. It is used to check the working performance of the color decoder.

"Chinese Studies Education" is a book by Zhang Cheng. Generally speaking, Chinese language studies mainly refers to an academic system that uses classical Chinese books as a carrier to express the traditional social values and morals and ethics of the Chinese Hu manuscript nation.
Since the beginning of traditional Chinese culture and scholarship, traditional Chinese studies have undoubtedly included medicine, drama, calligraphy and painting, astrology, mathematics and physics, etc. These certainly belong to the category of traditional Chinese learning, but they can also be said to be an extension of traditional Chinese learning. Today, it is the reorientation of traditional culture by multiculturalism in China and the world.

To this day, Chinese culture has been neglected for a long time, probably nearly 100 years. In the past 100 years, it can be said that the Chinese people have no faith. Before the May Fourth Movement, private schools were still common, and the way to read books was still chanting.
However, after that, private schools were abolished, new schools were sprung up, and the orthodox way of reading chanting disappeared completely. One of the things I was pleased to do a while ago was that I heard that one of the classes held by Huading Academy was a chanting class, which was very good and was taught by Mr. Xu Jianshun. I finally saw hope, and it turned out that someone was still doing it.
Later, I participated in the later Chinese Studies Seminar of Huading Academy, and found that there were still many people doing the promotion of Chinese culture. Every teacher who teaches is also on the front line and is struggling for this cause. Parents also came to participate, and they all realized the importance of traditional culture to their children's lives.
Therefore, more and more people recognize Chinese culture, and the prospect is still good, after all, it is the study of a country, the soul of the root of China, how can it be lost?

Learning Chinese culture needs to be meticulous, people in modern society are generally more impetuous, and only those who are really influenced or interested in various kinds of people will persevere in learning Chinese culture. If the state does not pay attention to the construction of this aspect, it will be difficult for the development of Chinese culture.
-
Classical education of Chinese culture, which is what all people, including children, should learn. Modern society has reached a very chaotic point, and the classical education of Chinese culture will be accepted by more and more people. and the whole world.
But it's a process! Let's do our part to promote China's traditional culture!

Sinology education is the inheritance and development of excellent Sinology culture, which is conducive to promoting the spirit of the Chinese nation and enhancing national cohesion, especially for young people, the enlightenment of Sinology is very important, which is not only conducive to the inheritance of excellent culture, but also conducive to the integrity of children's conduct and promotes the all-round development of children. Therefore, now primary and secondary schools have gradually begun to pay attention to the enlightenment of Chinese culture education, and many Chinese culture training institutions have also been derived, and the development prospects are still good.

Many people think that Chinese culture is to sit there and read with their heads shaken their heads, or to fool a few words in front of friends, but in fact, I think: Chinese culture is a country's culture, not Confucianism is national culture, China from ancient times to the present, after so many years, is a multi-ethnic country slowly integrated, this integration is not only the integration of people's living environment, but also the integration of various cultures, not only including the cultural integration of our ancient land, but also the integration of foreign cultures, since the integration, Then you have to go to the chaff, and this essence is enough to become Chinese culture.
Chinese culture education is the education of these cultures, don't criticize Chinese culture as nothing, I appreciate a sentence: superstition - obsessive or unbelieving; obsessive and believing; Lost and believed. If you say that Chinese culture is bad at the beginning, then, please first understand what Chinese culture is, and then judge whether Chinese culture is good, and say a modern saying:
If you don't know what Sinology is, it's better not to define Sinology first.
The above is a personal opinion, for reference only, and cannot be put on the platform.

I believe that the essence of Chinese culture is to be able to govern the country and secure the country. And the purpose is to be able to cultivate oneself, work together as a family, and govern the country. To study Chinese culture, you must have a lofty ambition and know the value of your coming to the world in this life, not for you, but for you.

I don't understand, it feels like another return to Confucianism. It will be a while, and I will make a fuss every few years. Chinese culture has accumulated a lot of things for 5,000 years, and it is always staring at that bit of morality and ethics, not to mention these strict ethical concepts, which are quite restrained and annoying.
I am an advocate of a free spirit, and I don't like the kind of learning that Wei Kejin can't write family letters. The path of learning is so narrow!
However, there is indeed a very interesting phenomenon, our parents and children do not like to delve into antiques very much, but we are happy to see people outside learning our old-fashioned knowledge. In fact, we feel that we either have a sense of identity, or a sense of respect for our ancient culture——— but we ourselves are undoubtedly more willing to pursue modernization and progress, at least for the ancient culture, we should also study more than specialize, and if we don't like to delve into the small alleys of Confucianism, we won't come out.

In the final analysis, it is the truth of learning.

The name of "Chinese Studies" began at the end of the Qing Dynasty. At that time, European and American scholarship entered China, called "new learning", "Western learning", etc., in contrast, people collectively referred to China's inherent learning as "old learning", "middle school" or "national learning".
Guoxue refers to ancient Chinese doctrines. Among them is the pre-Qin princes, the founder of Chinese culture - Confucius statue.
The ideas and theories of the pre-Qin princes had a profound impact on traditional Chinese culture. They formed the ideas of Bingjia, Legalism, Mohism, Confucianism and Taoism. These ideas deal with how to govern the country in a variety of different ways.
It has had a profound impact on the rulers of all dynasties, and slowly formed the traditional Chinese cultural concept.
Guoxue can be translated as "guoxue" (transliteration) and "sinology" (transliteration, referring to Chinese studies or sinology). The Chinese culture generally mentioned now refers to a set of unique and complete cultural and academic systems based on the pre-Qin classics and Zhuzi Studies, covering the classics of the Han Dynasty and the Han Dynasty of the Han Dynasty, the metaphysics of the Wei and Jin dynasties, the science of the Song and Ming dynasties, the Han Fu of the same period, the poetry of the Tang and Song dynasties, the Yuan Qu and the Ming and Qing dynasties, and the historiography of the past dynasties. Therefore, in a broad sense, ancient Chinese and modern culture and scholarship, including ancient Chinese history, thought, philosophy, geography, politics, economy, and even calligraphy and painting, Yixue, mathematics, medicine, astrology, architecture, etc., are all categories involved in Chinese studies.
Throughout human history, ignorance of the world outside the individual itself has caused the tragedy of the individual's own behavior, Confucianism emphasizes that a gentleman is not a weapon, a person who cannot be erudite and knowledgeable is impossible to become a gentleman, and a person who only understands one aspect is only a blind man touching an elephant, and must have ideological limitations, because it can be considered that the bottleneck of a person's development is the bottleneck of wisdom. And wisdom is the integration of knowledge. Traveling thousands of miles, is on the basis of breaking 10,000 books, through the line to achieve the expansion and testing of knowledge, to achieve a spiral rise, for the expansion of vision and thinking, the so-called knowledge, must be seen first and then recognized, the modern Confucian King Kaiyun also proposed that those who have achieved great success must climb the mountains and rivers to be magnificent, visit the people of the Quartet to enrich their minds. <> >>>More
