瞬變現象 的英文怎麼說
中文拼音 [shùnbiànxiànxiàng]
瞬變現象
英文
tra ient phenomena-
Provided with a case of pencils, and some sheets of paper, i used to take a seat apart from them, near the window, and busy myself in sketching fancy vignettes, representing any scene that happened momentarily to shape itself in the ever - shifting kaleidoscope of imagination : a glimpse of sea between two rocks ; the rising moon, and a ship crossing its disk ; a group of reeds and water - flags, and a naiad s head, crowned with lotus - flowers, rising out of them ; an elf sitting in a hedge - sparrow s nest, under a wreath of hawthorn - bloom
我拿了畫筆和畫紙，遠離她們，在一個靠窗的地方坐下，忙乎著畫一些幻想的人頭象，表現瞬息萬變萬花筒似的想象世界中剎那間出現的景象。例如，兩塊巖石之間的一片大海，初升的月亮，橫穿月亮的一條船，一叢蘆葦和景象，一個仙女頭戴荷花從中探出頭來，一個小精靈坐在一圈山楂花下的籬雀窩里。It was at the beginning of 1934, while working on the emission of these positive electrons that we noticed a fundamental difference between that transmutation and all the others so far produced ; all the reactions of nuclear chemistry induced were instantaneous phenomena, explosions
到1934年初，我們在研究這些正電子排斥現象時才注意到，在蛻變和當時產生所有其他反應之間存在著一種根本性區別：所有被誘導的核化學反應都是瞬時現象，即爆炸現象。If 1839 invention of photography, change several century since the people watching and knowing peripheral visual angling of thing, it becomes possible to catching and reproducing in the twinkling of an eye to enable ; then in today, it photographs to be each handheld people of camera not merely, can used for, record one ‘ s own daily life, give play to general way that individual imagine and create, a kind of independent form of contemporary art, the experiment of pioneer whose an idea and technology make up - - and tian taiquan ‘ s photography works, is the pipeline attempting to find chaining between these two, this is value that his photography can appear too
如果說， 1839年攝影術的發明，改變了人們數世紀以來觀看和認識周邊事物的視角，並使對瞬間的捕捉和再現成為可能；那麼在今天，攝影不僅僅是每個手持照相機的人，都可以用來記錄自己的日常生活、發揮個人想象與創造的普遍方式，還是當代藝術的一種獨立形式，一個觀念與技術彌合的先鋒實驗? ?而田太權的攝影作品，就是試圖在這兩者之間找到鏈接的管道，這也是他的攝影得以呈現的價值。We suggest to study a special kicked rotor moving in a piecewise continuous force field. when adjusting a control parameter the system displays a transition from conservative to quasi - dissipative, and a change of a stochastic web formed by the set of the images of the discontinuous borderlines to a transient stochastic web
它在一個控制參數連續改變時可以演示從分段連續保守系統向類耗散系統的連續過渡，從而展現不連續邊界象集隨機網向一個瞬態隨機網，以及網上的無邊界混沌擴散運動向局域規則運動的轉變。It can be seen from the deformation courses of the tubes that the local dents firstly occur at the beginning of impact. with the growth of the dents, the stiffness decreases, and the rigid - body translations and the whole deformations take place. the initial kinetic energy of the missile decreases rapidly to approximate zero during the course of impact, and the energy is transferred to internal energy and kinetic energy of the tube
同時，也得到了一些實驗中沒有觀察到的現象：從模擬的管梁的變形歷程可以看出，在沖擊瞬時，管梁先發生局部凹陷，隨著局部凹陷的加大，管梁的抗彎剛度減小，然後太原理工大學碩士學位論文剛體平動和整體變形發生，而且速度越大，這種現象越明顯;子彈的入射動能在撞擊過程中急劇減小，撞擊結束后減小到可以忽略不計。Not only analysis the results of experiment taken on the cavitation unit of transient flowing research set, this thesis also studies the cavitation characteristics by calculating two relative maths models. then, principles of pressure and speed in different durations : generation, development and disappearance, are gained
在利用瞬變流實驗臺空穴特性研究段進行實驗分析的同時，本文還應用兩種數學模型對空穴現象進行了計算分析，得出了空穴在產生，發展和消失各階段的壓力，流量變化規律。It has high resolution of frequency and low resolution of time in low frequency part this characteristic is fit to probe normal signal with instantaneous abnormal phenomenon and show its components. so, wavelet transformation is seen as signal microscope. there is good effect to detect malfunction in dynamic system by means of continuous wavelet transformation
這很適合於探測正常信號中夾帶的瞬態反常現象並展示其成分，所以被譽為分析信號的顯微鏡，利用連續小波變換進行動態系統故障檢測與診斷具有良好的效果。But in the moderate electric field 150 kv / cm, there is a sharp change in the configuration and charge distribution of the exciton, i. e. the exciton is directly split into an electron polaron and a hole polaron. the polarization and dissociation happen at a same time, which differs from that in conjugated polymers. and in the strong electric field 350 kv / cm, appear structural phase transition of the chain and luminescence quenching
同時得到兩個重要的臨界電場值： 1激子解離電場ec1 （ 150kv / cm ） ，在此電場下激子發生瞬間解離，成為電子型極化子和空穴型極化子； 2結構相變電場ec2 （ 350kv / cm ） ，在ec2下二聚化晶格開始被等距晶格取代， ptcl絡合物鏈發生結構相變，並伴隨peierls能隙漸趨消失和發光猝滅的現象出現。Wavelet transform has the ability of denoting local signal characteristics, so it is fit to analyzing instantaneous and fantastic phenomena and can lay out signal components
小波變換具有表徵信號局部特徵的能力，適于分析信號中的瞬態和奇異現象，並可展示其成份。Abstract : by using 2 - d finite element method ( fem ) and experiment, the phenomenon of heat conduction in tc11 ti alloy compressor blade is simulated and analyzed during the post - forge cooling course, and the time _ variation characters and distribution laws of transient temperature fields of every airfoil section are obtained
