Intra particle adsorption , diffusion and a first - order reaction occurring within the porous particle are considered in the present formula 近似式所考虑之现象包括颗粒内之吸附、扩散及一次反应。
Secondly , the concept of sustainable development is the response of the international communities to face the conflicts of environment and development for a long time 其次,可持续发展的理念,乃是国际社会面对长期以来发展与环境的冲突,所作的一次反应。
But the vvidbv strain gx8 / 99 that had been identified by gui only have saci side , and no sspl , the reason need farther research . according to the specific different sequence between cibdv and vvibdv in vvp2 gene . we also designed two sets of primers ( cibda + cibds and vvibda and vvibds ) 另外,针对不同强弱毒株的1 v的pz高变区序列的差异:设计合成了vvibdv的型特异性引物( ibda vvibds人建立型特异的rt pcr ,只需一次反应即可区分cibdv和vvibdv 。
一次: once反应: neaction第一次反应,初次反应: first set reaction次反应: secondary response第一次反射: first reflection非一次反射: nonprimary reflection一次反复: one replication一次反射: one hop; primary emission; primary event一次反射法: single bounce technique一次反射器: primary reflector一次反射束: once-reflected beam初次反应: first set graft reaction; primary reaction二次反应: reaction of second order; second set reaction response; second-set reaction; secondary reaction二次反应堆: secondary reactor高级次反应: higher order reaction逐次反应: successive reaction广义一次反射: generalized primary reflection一次次反复,再次: over and over (again)一次反射路径: single reflection path一次反射脉冲: once-reflected pulse单次反应发作: single episode of reactions再次反应发作: recurrent episodes of reactions零级反应;零次反应: zero order reaction三级反应;三次反应: third order reaction第一次反法同盟: first coalition
