在固體浸沒透鏡底面的近場區域，出射光場發生了退極化，使得出射總場的光斑有了一定程度的「增寬」現象。Faculae ? extra - bright areas between granules ? appear to rise above the surface ; they may account for the increased output during solar maximums
米粒之間最明亮的光斑，則是在太陽極大期時，物質激烈噴發沖出表面所造成。For the hyper accuracy interpolation technique, which resolves the accuracy limitation of pixel physical size, derives out the star spot interpolation accuracy limitation based on the star spot mathematical model and photoelectric statistics
針對克服像元尺寸對測量精度限制的超精度內插細分技術，在建立了星點光斑數學模型的基礎上，利用光電統計理論，推導了星點光斑內插細分精度的極限公式。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。Sik sik yuen wong tai sin temple decorated in a riot of colours, wong tai sin is an excellent example of a traditional chinese temple. yellow latticework and multicoloured carvings complement the temple s red pillars and golden roof
嗇色園黃大仙祠是傳統中式廟宇的表表者，色彩斑斕的外墻，黃色的窗欞，鮮艷奪目的雕像，配以紅色的柱子及金光閃耀的屋頂，極具典型廟宇的特色。The pd packaged in the laser diode can detect the signal of the self - mixing speckle interference and determine the motion state of the target
封裝在半導體激光器另一側的光電二極體，檢測光學反饋生成的自混合散斑干涉信號，確定物體的狀態。In fact, hartmann - shack wavefront sensor is affected by the noise of ccd and the constructed error too. in our compare, a bridge is setup, which is the original wavefront composed by zernike polynomial, we transform the original wavefront into far field. then we can compare the accuracy of hartmann - shack wavefront sensor with the accuracy of the system of far field diagnosis in detecting the farfield, using diffraction limit and encircle energy
我們在進行兩者相互比較的過程中，搭建了一個比較的橋梁，即由zernike多項式組成的各種原始像差波前，將它也變換到遠場作為原始理想遠場光斑，然後，以它的衍射極限和環圍能量曲線作為評價標準，比較hartmann - shack波前傳感器和遠場測量系統在光束質量診斷中的探測精度。Based on the rate - equation theory of four - level system, the expressions of threshold pump power, output power and slope efficiency are given. the influence of space distribution of pump light ( the position of focusing point, dimension of pumping light and divergence angle ) to the output characteristics are also discussed. then, by investigating the effects of thermal effect of laser crystal on the size of laser cavity mode, we obtain the mode - matching principle of high power laser diode end - pumped solid - state lasers
其中，在泵浦光的空間分佈變量中我們分別考慮了泵浦光聚焦后的腰斑大小、聚焦腰斑在增益介質中的位置以及泵浦光在介質中發散角的影響；然後我們研究了在高泵浦功率下激光晶體因吸收泵浦光而產生的熱效應所導致的熱透鏡效應以及熱致衍射損耗，通過分析它們對振蕩激光腔模尺寸的影響，得到了高功率半導體激光二極體端面泵浦固體激光器模式匹配的要求，為高功率連續單頻nd ： yvo _ 4激光器的優化設計提供了理論依據。In the lecture, dr lui will provide the latest knowledge of nearby space environment, examine the correlation between space disturbances and our daily lives, including the radiation dosage for frequent airplane travelers compared to that of workers handling nuclear fuel, explain sun activities such as sunspots, solar flare, solar wind and space storms, etc. and how they will damage space assets and satellites for communication and navigation systems that our mobile telephone network, television broadcasting and flight routes will also be affected
講座上呂博士將以深入淺出手法，介紹科學家對太空天氣的認知預報研究工作，以及黑子耀斑風暴地磁暴和極光等太陽活動，對我們日常生活的影響，如經常乘坐飛機旅客跟核電廠工人所受的幅射影響比較，以及太空天氣對地球的實質影響。分享友人
