Histidine and cysteine derivatives can coordinate with zinc , but the uv or fluorescence spectral changes are not significant enough to allow effective detection of zinc in plant system 组氨酸和半胱氨酸的衍生物能与锌配位，但锌离子的加入对紫外图谱或荧光图谱的影响并不显著，因此不大可能有效地标记植物体系中的锌离子。
The so made silica gel glass has quasi - inkbottle shape and median pore size distribution of 5 - 8nm which is suitable for the doping and protection of mpc molecules . mpc molecules in matrix always have a strong tendency to dimerization that can badly affect the linear absorption spectrum , causing quench of dye fluorescence and change the yield of photochemical processes . it is a vital problem that worth more attention 鉴于酞普的二聚化是影响其非线性性能和光限幅效应的重要因素，应用紫外一可见吸收光谱( uv / vis )测试技术，跟踪研究了复合体系在溶胶一凝胶转变过程中酞蓄二聚化的产生机理、主要影响因素和变化规律，提出了可能有效抑制二聚的技术途径。
At last , according to the reasons causing chinese commercial banks " credit risk i put out some aiming suggestions : chinese commercial banks credit risk must be controlled , been on guard and cut off from both outside and insde banks . it is possible to manage and be on guard banks " credit risk effectively only by improving macro environment , carrying forward corporation reform and improving chinese banks " management system at the same time 最后根据我国商业银行信贷风险的成因提出了针对性的建议，即控制，防范和化解我国商业银行信贷风险要从银行外部和内部同时着手，改善宏观环境，推进企业改革和健全我国银行管理机制要同时进行，惟此，才有可能有效地控制和防范银行信贷风险。
An available name which either ( 1 ) is objectively invalid ( i . e . it is a junior homonym or a junior objective synonym of a potentially valid name , or must be rejected under the provisions of the code , or has been suppressed by the commission ) , or ( 2 ) is subjectively invalid ( because it is considered subjectively to be a junior synonym or to be inapplicable to a particular taxonomic taxon ) 一个适用名称,如为( 1 )客观地无效(亦即一个次异物同名,或一个可能有效名称的次客观同物异名,或为一个在本规约规定下必须被摒弃或已被委员会禁制的名称) ,或( 2 )主观地无效(因为在主观上认为是一个次同物异名,或不能应用于一个特别的分类学分类单元者) 。
