amplification reaction造句

• The work mainly consists of four parts : the first part is to use oxidation and lpcvd technique to produce sio2 mask film and si3n4 insulation film in order to enhance the heating efficiency of micro chamber , and guarantee the carry out of the reaction . the second part is to use the combination of dry etching and wet etching to produce reaction micro chamber , it is the container which carry out the pcr reaction , and dna sample carry out amplification reaction here . the third part is to use the sputtering , photolithography to produce heaters and temperature sensors which heat the reaction micro chamber and provide the temperature condition for the pcr reaction
  首先，利用氧化工艺和lpcvd技术，生长sio _ 2掩膜层和si _ 3n _ 4绝缘层，以提高反应腔的热效率，保证扩增反应的顺利进行；其次，用湿法腐蚀和干法刻蚀相结合的方法加工微型腔体，使之作为dna样品进行pcr扩增反应的容器；第三，用溅射、光刻等工艺在微型腔体底部制作微型加热器和温度传感器，实现对反应腔体的加热及其温度的精确测量，提供pcr扩增反应所需的温度条件。
