The contents of metal elements in silk gland and silk fiber of b. mori silkworm have been detailedly analyzed by proton induced x - ray emission ( pixe ), inductively coupled plasma mass spectroscopy ( icp - ms ) and atomic adsorption spectroscopy ( aas )
摘要用不同的測試方法,即質子誘導x射線發射( pixe ) 、電感耦合等離子體質譜( icp - ms )和原子吸收光譜( aas )對桑蠶絲腺體和絲纖維中金屬元素的含量進行了詳細的表徵。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。The peak at shorter wave length side is assigned to be the electronic transitions between lumo and homo and that at longer wavelength is considered to be originated from excitons. to prove this assignment we draw support from study on ionization of excited luminescent centers in inorganic materials. we really observed the same behavior
利用無機材料中的碰撞離化,無機有機復合的類陰極射線激發及雙極注人的相互補充、疊加、一個加強另一個過程的關系,可以把它們集成在一起,如再加一電子阻擋層,則可更充分地利用獲得的電子,使電場誘導發光的性能如光強、光譜。Because there are no enough efficiency methods to dispose pollute, so to study and develop new methods is very urgent. we do some work to study on the radioresistance bacteria deinococcus radiodurans to construct one super bacteria, which could resolve the pollution in a complex environment contaminated by both radiation and organic compound
同時針對耐輻射奇球菌deinococcusradiodurans對電離輻射、紫外線、乾燥、強氧化劑和一些化學誘變劑的驚人的抗性,對構建在放射性和有機鹵代物污染的復合環境中具有生物修復功能的超級基因工程菌方面做了初步的研究,以發展有效清除環境污染的新途徑。分享友人
