I consider those issues existential in nature. One of the problems with my life in America was that I felt it had no purpose. I went to work every day and even did what I could to make my colleagues39。 he wondered how in the world he came to belong there. Indeed his penning and publishing this essay caused his exmunication from high society and also caused him a lot of legal trouble. The legal trouble came as a result of the fact that he was speaking out against the government. I like to reference such texts from time to time as an example both of the fact that history does repeat itself and that this world is not so big that what applies to one society does not in any way touch another society. On a much smaller scale,Emerson39。s to e and recapping the key points. This device, not used in the original, is culturally understandable but artistically mediocre. What puzzles me is the two new songs for the opening and end credits. They were written in English, but sung by Chinese with an unfortable accent. They were obviously designed to appeal to an Englishspeaking base, but do not jibe with the Chinese dialogue. Speaking of the dialogue, the English translation, picked apart by some Chinese, is too literal for my taste. I can imagine a typical American hit by a flurry of royal ranks, addresses and greetings, even multiple names and titles for the same person. The first half hour must be a swamp to wade through, very much like my experience of getting through a Tolstoy tome with its endless inflections of names transliterated into lengthy Chinese. I see the choice of verbatim translation as an effort for conveying exotica. It is fairly petent, with no error that I could detect, but fails to rise above words or capture the essence of the language. A cultural product usually crosses over to a foreign territory first by an emphasis on the monalities. But whether inside or outside China, the temptation to sell it for the differences is just too great. Sure, the sumptuous sets and costumes are a big attraction, but the narrative technique has bee－ how shall I put it?－ a bit anglicized, which is necessary for cultural export. Judging by the responses, this legend, which, contrary to the claim of the English trailer, is totally fictitious, has departed from China but not yet landed on American shores. I am a big fan of Ralph Waldo Emerson39。s president, who is also a renowned tenor, tells China Daily. During a tour in 1985, he went to a village and met an elderly local man, who told him a story about his friendship with a solider from Shenyang, capital of Northeast China39。t just about sharing art with nomadic families but also about gaining inspiration for the music and dance. Ulan Muqir literally translates as red burgeon, and today39。s Zhangye city during their journey to Kazakhstan, May 5, 2022. The caravan, consisting of more than 100 camels, three horsedrawn carriages and four support vehicles, started the trip from Jingyang county in Shaanxi on Sept 19, 2022. It will pass through Gansu province and Xinjiang Uygur autonomous region, and finally arrive in Almaty, formerly known as AlmaAta, the largest city in Kazakhstan, and Dungan in Zhambyl province. The trip will cover about 15,000 kilometers and take the caravan more than one year to plete. The caravan is expected to return to Jingyang in March 2022. Then they will e back, carrying specialty products from Kazakhstan A small art troupe founded six decades ago has grown into a household name in the Inner Mongolia autonomous region. In the 1950s, Ulan Muqir Art Troupe was created by nine young musicians, who toured remote villages on horses and performed traditional Mongolian music and dances for nomadic families. The 54yearold was born in Tongliao, in eastern Inner Mongolia and joined the troupe in says there are 74 branch troupes across Inner Mongolia and actors give around 100 shows every year to local nomadic people. I can still recall the days when I toured with the troupe in the early 39。在設(shè)計(jì)過(guò)程中我發(fā)現(xiàn)自己考慮問(wèn)題很不全面，自己的專業(yè)知識(shí)掌握的很不牢固，所掌握的 電路 應(yīng)用軟件還不夠多，我希望自己的這些不足之處能在今后的工作和學(xué)習(xí)中得到改善。通過(guò)這次的畢業(yè)設(shè)計(jì)， 我能運(yùn)用已學(xué)的知識(shí)解決我在設(shè)計(jì)中遇到的問(wèn)題，使我 思考問(wèn)題的能力得到了很大的提高。它才是一個(gè)設(shè)計(jì)的靈魂所在。 本設(shè)計(jì) 主要講述了 智能 搶答器的工作原理和 工作過(guò)程 。 411搶答器工作原理電路圖 21 搶答器 PCB 板電路圖 通過(guò)對(duì)電路的一些功能需求分析，我們運(yùn)用了 Protel 99 SE 軟件對(duì)電路圖進(jìn)行了設(shè)計(jì)，將搶答器 PCB板電路圖設(shè)計(jì)出來(lái)，如圖 421所示。 圖 342 555 定時(shí)器工作原理圖 19 圖 343 555 定時(shí)器內(nèi)部邏輯電路圖 將 NE555多諧振蕩器與成音多諧振蕩器連接起來(lái)，前一個(gè)振蕩器的輸出接到后一個(gè)振蕩器的復(fù)位端，后一個(gè)振蕩器的輸出接到揚(yáng)聲器上。當(dāng) uc下降到 uc≦ 1/3Vcc 時(shí)，則電壓比較器 C1和C2的輸出 uc1=1和 uc2=0，基本 RS觸發(fā)器被置為 1， Q等于 1， Q非等于 0，輸出 uO由低電平 UOL躍到高電平 UOH。當(dāng) uc≧ 2/3 Vcc 時(shí)，電壓比較器 C1和 C2的輸出分別為 uc1=0,uc2=1,基本 RS觸發(fā)器被置 0， Q等于 0， Q非等于 1，輸出 uO躍到低電平 UOL。 圖 341搶答器報(bào)警電路 顯示字符 g f e d c b a 0 0 1 1 1 1 1 1 1 0 0 0 0 1 1 0 2 1 0 1 1 0 1 1 3 1 0 0 1 1 1 1 4 1 1 0 0 1 1 0 5 1 1 0 1 1 0 1 6 1 1 1 1 1 0 1 7 0 0 0 0 1 1 1 8 1 1 1 1 1 1 1 18 由 NE555接成音多諧振蕩器構(gòu)成的報(bào)警電路如圖 341所示。 圖 325鎖存優(yōu)先功能電路圖 16 圖 331數(shù)碼顯示管原理圖 搶答器設(shè)計(jì)中的數(shù)碼顯示電路 共陰式 LED數(shù)碼管的原理圖（ 圖 331數(shù)碼顯示管 原理 圖 ），使用時(shí)，共陰極接地，7個(gè)陽(yáng)極 a~g由相應(yīng)的 BCD七段譯碼器來(lái)驅(qū)動(dòng)。通過(guò)對(duì) 09 這 10個(gè)數(shù)字的分析（見(jiàn) 圖 325鎖存優(yōu)先功能電路圖 ）可以看到，只當(dāng)數(shù)字為 0 時(shí)，才出現(xiàn) d 為高電平 ， 而 g 為低度電平 ， 這時(shí) Q1 導(dǎo)通 ， D1 D14的陽(yáng)極均為低電平 ，
