繞射譜 的英文怎麼說
中文拼音 [ràoshèpǔ]
繞射譜
英文
diffraction spectrum-
The wavelengths of reflectance peaks and vales are got by spectral derivative method in section 3. 3. mechanism of them is analyzed. red tide and normal seawater, as well as some different dominant species of red tide, such as chattonella marina and mesodinium rubrum, can be discriminated by using the wavelength information of second reflectance peak
3 . 3節運用該方法得出了實驗赤潮水體光譜曲線的兩個反射峰和一個吸收峰的波長范圍，並對其產生機理進行了分析;更為重要的是，利用光譜曲線第二反射峰的波長位置實現了赤潮與非赤潮水體的光譜辨別，以及紅色中繞蟲、海洋褐胞藻等不同優勢種類赤潮的識別。In addition, conventional surface analytical tools, i. e., leed and aes, are also equipped to provide surface information of long - range order and elemental identity
傳統的表面分析設備如低能電子繞射儀（ leed ）及歐傑電子能譜儀（ aes ） ，則用來決定晶體表面的長程結構和元素成份。On the other hand, the multi - level fast mutipole algorithm ( mlfma ) which based on the integral equation method can obtain the result with great accuracy, but this method accounts in all the couplings between every sub - scatter objects, it needs much more to store all of the information, and because of the rigorous integral on the spectrum space the computational complexity is also enormous
相對於一些傳統的方法如幾何光學方法，幾何繞射方法，彈跳射線方法有著更高的精度和更廣的適用范圍。但是由於其基於積分方程方法，需要對全局中所有的子散射體之間的相互耦合加以考慮，從而導致在求解電大尺寸目標的散射問題時需要巨大的存儲空間。同時由於其在譜域上嚴格積分導致計算量也很大。And when observers take a spectrum of the galaxy, the diffraction grating of the spectrograph disperses the light over a large area on the detector, rendering the signal even fainter at each wavelength
而當觀測者擷取星系光譜時，光譜儀的繞射光柵會把光分散到偵測器上一個很大的?圍，導致每個波長上的訊號更加微弱。分享友人
