Both UV-A and UV-B irradiation induced DNA damage in mesophylls. The level of DNA damage was much higher in younger than mature leaves, which indicates that young leaves are more sensitive to UV-B radiation than mature leaves.

彗星检测结果表明，九里香叶片DNA的损伤程度与UV-B辐射的剂量呈正相关；在相同UV-B辐射剂量下，九里香幼嫩叶片比成熟叶片的DNA损伤量大，表明其幼嫩叶片对UV-B辐射的敏感性比成熟叶片高。

The temperature accelerated the migration rate and affected on the distribution ratio of Irgafos 168 between HDPE film and fatty food simulants .

用反相高效液相色谱分析测定了不同温度下，正己烷、异辛烷和95%乙醇作为脂肪食品模拟物时，HDPE膜中Irgafos168的迁移量。

Based on the conservation law, applying appropriate rezone methods for meshes we modify the 9-point method to reduce computation error due to poor regularity of the meshes and low precision due to the approximation to vertices values by an average of neighboring cell values. The nonlinear system obtained is a different system from the 9-point scheme.

该方法从守恒方程出发，将九点差分格式应用于按某种合适的方式进行重分之后的网格上，减少由于网格正则性差以及网格节点上的物理量采用周围网格量的加权平均等原因所引起的计算误差，得到一个新的但其解仍然逼近原来网格上的物理量的方程组。

3种萃取方法的回收率均可满足饮用水中痕量拟除虫菊酯类农药的分析，以正己烷快速混合萃取回收率最高。

Based on the relationship between the numerical aperture of the objective lens and scale pitch, this study chooses a suitable Plano-convex lenses available on the market, so as to approximate the diameter of the focusing spots to scale pitch. Also, by using the optical path of an optical encoder similar to the nanoscale, the changes in the surface profile of the scale can be measured directly, so as to obtain the two quadrature sinusoidal signals. By counting the zero crossing of these two quadrature sinusoidal signals and calculating the interpolation value of these two quadrature sinusoidal signals, the moving direction and moving displacement value of the scale can be obtained.

研究中再以搭配物镜的数值孔径与尺条间距的关系，选择ㄧ适当的市售平凸透镜，使聚焦光点的直径与尺条的间距相近，并使用相同於奈米级长行程双雷射聚焦读头装置的光路设计，如此将可藉由直接量测尺条的表面轮廓变化，以获得一组正交弦波讯号，继而利用讯号四分割与细分割处理，计算出尺条之移动方向与移动量，研制出一实用性长行程双雷射聚焦读头光学尺。
