1). The transmittance efficiency in the UV range (280–400 nm) was 18–21%, 53–54% and 56–59% for T. punctifera, C. granii and T. pseudonana (Fig. 1), respectively. The opposite trend was seen in reflectance which for all three species decreased with increasing wavelength. A...
the light transmission through the bacterial suspensions was smaller at shorter wavelengths. Figure2cshows the light transmission of in the spectral range of the DUV-LED source, and Supplementary Fig.S1shows transmission over an expanded spectral range (220 nm to 900 nm). In Fig.2c, the ...
Seven percent of the electromagnetic radiation emitted from the sun is in the UV range (200–400 nm). As it passes through the atmosphere, the total flux transmitted is greatly reduced, and the composition of the UV radiation is modified... H Frohnmeyer,D Staiger - 《Plant Physiology》 被...
2.1选择 中的 （photometric光度），打开光度模块。2.2单击光度计键条中的 （baseline基线），启动基线校正操作。 2.3当基线参数对话框（baseline Parameters）弹出时：在开始波长和结束波长中分别输入实验所需的波长范围内进行基线校正,点击 OK。 例如，在Start中输入700，在 End中输入300，点击 OK，从700nm开始...
