Whether it has conducted regular sample tests on the contents of fluorescer and bacteria for various kinds of paper tissue products on the local market ; if it has , of the test results and whether the scope of the sample tests covers napkins made of recycled paper , paper tissue products sold at major supermarkets , and paper tissues given away by restaurants and newspaper stands for free ; if it has not , whether it will consider conducting regular sample tests annually 有否定期抽查本港市面上各类纸巾产品的萤光剂及细菌含量若有，结果为何及抽查范围是否包括环保纸餐巾各大型超级市场所售卖的纸巾，以及餐厅和报纸摊档所赠送的纸巾若没有，会否考虑每年进行定期抽查

Some by - products of this work can be used as routine tools in the uv laser laboratory . commercial video ccd cameras are used to image uv laser and soft x rays , window glass as a fluorescer is used to indirectly measure the uv laser beam profile with high energy density , and a special glass which permits uv light to pass through while absorbs the visible , is introduced into the uv beam profiling in strong visible stray light environment 实验中发展了一些测量技术，例如用可见光视频ccd直接测量紫外激光的光束分布和激光等离子体产生的x光二维图象，利用窗玻璃作为荧光体测量能量密度较高的紫外光束分布，利用可见吸收紫外透射玻璃制成的衰减器测量有严重背景光的紫外光束分布，可以作为实验室的常规测量工具，并有一定的推广价值。
