Caption : : the dramatical phenomenon, is characterised by having a dashing luminance in the upper layer of the atmosphere, created by the collisions of energetic particles of solar wind with the atoms and molecules in the polar areas
當太陽風被地球磁場引領至兩極地區，與地球大氣層的粒子發生碰撞時，便會形成極光，宛如一張色彩斑瀾的輕妙掃過夜空，絢麗奪目。The recent researches on observations of h line profile asymmetry in chromospheric flare are reviewed. spectral properties, the corresponding mechanisms of asymmetry, and reproduction of observational spectrum by using semi - empirical atmosphere model are dicussed in detail. at last, the main problems to be solved and further researches are put forward
綜述了近年來太陽色球耀斑爆發時h譜線不對稱性的研究進展，著重討論了光譜特徵和與其對應的不對稱性產生機制，以及利用大氣半經驗模型再生觀測譜線輪廓不對稱性等方面，並提出尚待解決的主要問題和進一步的研究方向。That forest - dell, where lowood lay, was the cradle of fog and fog - bred pestilence ; which, quickening with the quickening spring, crept into the orphan asylum, breathed typhus through its crowded schoolroom and dormitory, and, ere may arrived, transformed the seminary into an hospital
羅沃德所在的林間山谷，是大霧的搖籃，是霧氣誘發的病疫的滋生地。時疫隨著春天急速的步伐，加速潛入孤兒院，把斑疹傷寒傳進了它擁擠的教室和寢室，五月未到，就己把整所學校變成了醫院。The sequence of two patterns presence is changed alternately, that is, one pattern will appear at the second pulse of total pattern in this half cycle if it appears at first pulse in last half cycle. the stability of square pattern was studied by considering the interaction among the wall charges. the discharge moments of individual filament alternate from long one to short in the square pattern, which can been explained by using the breakdown and quench model through considering the wall discharge accumulated on the dielectric layers
實驗研究了正方網格斑圖與混合氣體的比例及外加電壓的關系，給出了班圖類型隨上述條件變化的相圖；實驗採用光學方法對正方網格斑圖進行了時空動力學測量，發現正方網格斑圖是由兩套正方網格斑圖相互嵌套而成，其中一套的微放電絲位於另一套正方形單元的中心，這兩套微放電絲交替進行放電；考慮到壁電荷之間的相互作用，研究了正方網格斑圖的穩定性；實驗發現正方網格斑圖的微放電絲放電時間間隔是長短交替變化的，考慮到電介質表面積累的壁電荷的作用，使用擊穿?熄滅方程很好的解釋了該現象。The optimized experimental conditions are determined and the densities of some elements in the mental alloy standard samples are measured. the experimental results shows that the spectral intensity of the plasma enhances significantly with the increase of the operating voltage and the power density. ( 1 ) to the steel ally sample, the emission intensities of the spectra reach to the maximum values when the laser operating voltage is 1600v and the argon pressure is 600 torr. under the same pressure, the spectral intensity of the plasma in the argon atmosphere is stronger than that in the air. when the argon pressure is 320 to rr, the signal - noise ration is about 5 times than that which the argon pressure is 700 torr, but the temperature of plasma is less about 1000k
（ 1 ）對于光譜標鋼準樣品，當激光器工作電壓為1600v 、氬氣壓力為600乇時，譜線強度達到最大，並且在相同壓強下，氬氣中的等離子體與空氣中的等離子體相比，其輻射強度明顯增強；氬氣壓力為320乇時的譜線信背比約為600乇條件下的5倍，而等離子體溫度卻下降了近1000k ，即等離子體溫度隨環境氣壓的增大而增大；當激光束的焦斑在樣品表面上下移動時，激光誘導量、等離子體的激發溫度、譜線強度都呈不對稱性分佈，其最大值對應的焦斑位置都位於樣品表面之下0 . 4mm左右。When he had escorted one guest to the hall, the count returned to the gentleman or lady who was still in the drawing - room. moving up a chair, and with the air of a man fond of society and at home in it, he would sit down, his legs jauntily apart, and his hands on his knees, and sway to and fro with dignity as he proffered surmises upon the weather, gave advice about health, sometimes in russian, sometimes in very bad but complacent french. then again he would get up, and with the air of a man weary but resolute in the performance of his duty, he would escort guests out, stroking up his grey hair over his bald patch, and again he would urge them to come to dinner
送走一位賓客后，伯爵回到那些尚在客廳未退席的男女賓客面前，他把安樂椅移到近旁，顯露出熱愛生活善於生活的人所固有的樣子，豪放地攤開兩腿，兩手擱在膝蓋上，意味深長地搖搖擺擺，他預測天氣，請教保健的秘訣，有時講俄國話，有時講很差勁的但自以為道地的法國話，后來又現出極度睏倦但卻竭盡義務的人所獨具的樣子去送賓客，一面弄平禿頭上稀疏的斑發，又請賓客來用午膳。分享友人
