射電洞 的英文怎麼說
中文拼音 [shèdiàndòng]
射電洞
英文
radio hole-
The authors studied the characteristics of element geochemistry, mineral assemblage and microtexture of the white reticulate clay in the quaternary laterite of the dongting basin with some experimental analysis methods, such as chemical analysis, x - ray diffraction analysis, ir and sem analysis. the genesis of the vermiculate reticulate clay and the rhizomatic reticulate clay in the quaternary laterite of the dongting basin are discussed. the formation of crannies or holes in the soil and the transference of soil elements are absolutely necessary conditions to form the white reticulate clay in laterite
在野外考察的基礎上，運用化學全量分析x射線衍射分析紅外光譜分析和掃描電鏡微形貌分析等實驗方法和手段，對洞庭盆地第四系紅土地層中網紋的元素地球化學礦物組合特徵和微形貌特徵進行了系統研究，對洞庭盆地紅土地層中2種主要的網紋類型蠕蟲狀網紋和根狀網紋的成因進行了探討。The output takes the form of hawking radiation
黑洞電腦輸出的是霍金輻射。Is the unit that supplies cooling water with temperature stability of 0. 05 to prevent temperature variation in various equipment such as light radiation unit accelerating tubes, high - frequency acceleration cavities and rf power sources
精密溫調裝置放射光設備加速管高周波加速空洞rf電源等機器溫度?動守溫度安定0 . 05That is the following in essence. a sufficient mass of cold matter will necessarily collapse to a black hole, and stars with different mass will evolve into the white - dwarf - star, the neutron - star or the black - hole eventually because of the radiation of the burning core. the collapse of stars with sufficient mass leads to a black hole endowed with mass and charge and angular momentum, no other adjustable parameters : " a black hole has no hair.
第二章簡單介紹一下「黑洞無毛」理論形成，即足夠質量的冷物質能夠塌縮成黑洞，不同質量的恆星由於核燃燒輻射最終會演化成為白矮星、中子星或黑洞，以及黑洞的終態系統唯一地由質量、電荷和角動量確定，而無其它物理參數，此即為「黑洞無毛」理論。Besides, successfully calculating the electromagnetic four - potential in the spacetime of charged black hole expressed by the generali zed spherical coordinate and furtherly solving the h - j equation of such spacetime make it possible to get the exact description of the energy extent of nonthermal radiation particle and to study the characteristics of such black hole ' s nonthermal radiation
另外，本文還求出了一類用扁橢球坐標表示的荷電黑洞時空中的電磁四維勢矢量，從而成功地求解了此類彎曲時空中的hh方程，得到了這種非熱輻射粒子能量范圍的精確表達式，從而對這類黑洞的非熱輻射特徵進行了研究。For example, one cannot bring out any of its mass, or receive a reflection back by shining a light source such as a flashlight, or retrieve any information about the material that has entered the black hole
舉例來說，不能夠帶走它任何的質量，或藉由照耀例如一個手電筒的一個光源接受反射回來的光，或取回有關已經進入黑洞的物質任何資訊。American tv stations went live showing the robot creeping along the 20 - centimetre - square 60 - metre - long shaft. as the robot inched along the rough - surfaced shaft toward the limestone door adorned with two copper handles, its path was lit by a blue beam. during the broadcast, dr hawass revealed a stone sarcophagus found in a tomb near the great pyramid containing the skeleton of a man thought to have died at the time of the pyramid ' s construction some 4500 years ago
電視轉播機器人拍攝的秘道情況，起初是漆黑一片，其後由照明系統放射出的光芒，僅可見狹窄秘道兩旁的巖石，但當機器人走到秘道盡頭，機器人將一個高解象光纖攝像機鏡頭伸入石門內已鉆好的洞后，攝影機拍攝出一個令所有人都感到驚訝的圖象原來石門後面還有一道新門。In 2002, based on the observation results from the chandra x - ray observatory and the hubble space telescope, astronomers employed computer to simulate the merging process of two supermassive black holes at the centre of ngc 6240
2002年，天文學家結合了陳德拉x射線天文臺和哈勃太空望遠鏡的觀測結果，用電腦模擬出星系ngc 6240核心兩個超級黑洞融合的過程。Recent theoretical calculations with super - computers using results from the chandra x - ray observatory seem to answer to last question in the positive. however, in that case, is there any chance we can derive more direct observational evidence
近期超級電腦分析錢德拉射線天文臺的數據，顯示中型黑洞極有可能存在然而我們可以更直接觀測這類黑洞的存在嗎？分享友人
