Selected answers

DC refers to direct current, expressed in DC.

The current whose direction remains unchanged is called DC current, which is generally called DC. That is to say, the electric quantity passing through the cross section of conductor in unit time is equal, which is called steady current or constant current (DC for short), also called "constant current", and the DC current should be represented by capital letter I.

AC refers to AC current, expressed in AC.

Alternating current (AC) refers to the current whose current direction changes periodically with time, and the average current in a cycle is zero. Unlike DC, its direction will change with time, while DC does not change periodically.

Generally, the waveform of alternating current (AC) is sinusoidal.

AC can effectively transmit power, but in fact, there are other waveforms used, such as triangle wave and square wave. The city power used in life is the AC with sine wave.

What does it mean to be quite tame

Smile and say goodbye

"Also quite tame" means that it is still very docile. It comes from the "Notes of Yuewei Thatched Cottage". The original text: "Wolf Ambition": "If you have a rich room, you will occasionally get two little wolves, who will be at peace with the domestic dogs and miscellaneous animals, as well as the dogs. If you are a little longer, you will also be quite tame, and the owner will forget that you are a wolf."
There was a rich family who got two little wolves by chance, and they were kept in captivity together with the dogs, and they were at peace with the dogs. The two wolves gradually grew up and were still very tame. The master forgot that they were wolves.
The subject matter of Yuewei Thatched Cottage Notes is mainly monsters, ghosts and foxes, but there are also descriptions of people, scenery, poems, articles, and allusions, which are quite extensive. Ji Yun's official career was smooth. His guiding ideology in writing this book was "the general purpose is not obedient to the wind and education". He adopted the writing style of the strange tales of the Six Dynasties. His narration was simple, not detailed, and not beautiful. It was very different from the description of "Strange Stories from a Lonely Studio".

The street lights far away are clear,
It seems that countless stars are shining.
The stars in the sky appear,
It seems that countless streetlights are lit.
I think the ethereal air,
There must be a beautiful market.
Some items on display in the market,
Surely there is no treasure in the world.
Look, the shallow Tianhe River,
Certainly not very broad.
The cowherd and weaver across the river,
I will be able to ride cattle.
I think they are,
I will surely wander in Tianjie.
If you don't believe me, please look at that meteor,
They are walking with lanterns.

Author of Guangling Essay

Floating dream

The author of Guang Ling San is Ji Kang, a musician of Wei Jin. Ji Kang (224-263 A.D., 223-262 A.D.), a native of Li County (now Suixi County, Anhui Province) in the State of Qiao, was a thinker, musician and litterateur in the Three Kingdoms period of the Cao Wei Dynasty.
Ji Kang was smart since he was young. He was seven feet eight inches long, and he stood out. He read extensively and learned many arts, especially the theories of Lao and Zhuang. In his early years, he married the Lord of Changle Pavilion, the great granddaughter of Cao Cao, Emperor Wu of the Wei Dynasty. He paid homage to an official doctor and awarded him the title of "Ji Zhongsan". After Sima took power, he lived in seclusion and refused to become an official. In the fourth year of Jingyuan era (AD 263), Sima Zhao, a senior general in power, was executed at the age of 40 because of the fall of Zhong Hui, a senior lieutenant of Sili.
The music score of Guangling San has 45 sections, which are divided into six parts: finger, small preface, big preface, positive tone, disordered tone, and postpreface. Before Zhengsheng, it mainly expressed sympathy for Nie Zheng's unfortunate fate; After Zhengsheng, he sang praises of Nie Zheng's heroic deeds. Zhengsheng is the main part of the music, which focuses on the emotional development process of Nie Zheng from resentment to indignation, and profoundly depicts his will to revenge against power and death rather than surrender.
