本課程將對漢語各大方言（包括官話、晉、吳、贛、湘、閩、客、粵等）的音韻、詞匯和語法特性做一個初步的介紹，而把重心放在南方方言上。In order to strictly control the blind development of some special kinds of consumer goods and goods in over - supply, no locality may reduce or exempt product taxes or value - added taxes on tobacco, alcoholic beverages, firecrackers, fireworks, clocks, watches, bicycles, sewing machines, electric fans, refrigerators, motorcycles, washing machines, vacuum cleaners, air conditioners, electronic keyboards, pianos, tv sets, tape recorders, cassette players, video cassette recorders, electronic video games, pull - top cans, canned beverages, aluminum doors or windows, architectural decorations, kilowatt - hour meters, saccharin, adhesive clay bricks or tiles, cosmetics for the skin and hair, and articles for use in a memorial ceremony, which are produced or marketed in that locality, regardless of the ownership or type of enterprise
一、為了嚴格控制某些特殊消費品、長線產品的盲目發展，無論什麼性質和類型的企業，生產銷售的煙、酒、鞭炮、焰火、鐘、表、自行車、縫紉機、電風扇、電冰箱、摩托車、洗衣機、吸塵器、空調器、電子琴、鋼琴、電視機、錄音機、放音機、錄像機、電子游戲機、易拉罐及易拉罐飲料、鋁合金門窗及建築裝飾材料、電度表、糖精、粘土磚瓦、化妝品、護膚護發品、焚化品，各地一律不得減免產品稅、增值稅。A large planar microphone array, which consists of 111 microphones, was successfully applied to obtain a two - dimensional mapping of the sound sources on a landing aircraft. the focus of study in this paper is on the landing gear noise source. the spectra, directivities and sound pressure levels of flap side - edge noise of 7 narrow - board commercial aircraft and 7 wide - board commercial aircraft are presented. it is found that the landing gear noise spectrum is broadband with some single tones in some cases. the directivity of the total sound pressure level of a landing gear noise resembles that of a horizontal dipole. the level differences between the various aircraft landing gears are larger than those expected from the airspeed differences. it is thus expected that the louder noise emission of the landing gears can be reduced by redesigning
應用由111個傳聲器組成的平面傳聲器陣列對當前流行的民用客機進場著陸過程中的機體噪聲源進行了實驗測量，本文對七架窄體客機和七架寬體客機的起落架噪聲進行了分析，得到了起落架噪聲的頻譜特性、指向特性和聲級變化.研究發現，起落架噪聲的頻譜是由寬頻隨機噪聲與一些較為明顯的單音噪聲源組成，起落架噪聲的指向性類似於一個水平放置的偶極子.不同飛機起落架噪聲的聲級相差較大，這說明可以通過重新結構設計降低起落架噪聲。Measurement methods of a - chain and b - chain electro - acoustic frequency response of motion - picture control rooms, review rooms and indoor theatres
