Through comparative analysis to the test data of tow sampling methods in drilling hole and sampling method in shaft, it was found out by the author that the drilling sampling method has obvious disturbance and depression to the soil sample, which caused the soil sample ' s dry density to be increased, porosity ratio to be decreased, filtration coefficient to be decreased, and modulus of compression to be increased
筆者通過對鉆孔兩種方法獲取的土樣與豎井土樣試驗數據的對比發現，鉆孔取樣對土樣有明顯的擾動和壓密作用，造成了土的干密度增大、孔隙比減小、滲透系數降低、壓縮模量增大。 -
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，利用氧化工藝和lpcvd技術，生長sio _ 2掩膜層和si _ 3n _ 4絕緣層，以提高反應腔的熱效率，保證擴增反應的順利進行；其次，用濕法腐蝕和干法刻蝕相結合的方法加工微型腔體，使之作為dna樣品進行pcr擴增反應的容器；第三，用濺射、光刻等工藝在微型腔體底部製作微型加熱器和溫度傳感器，實現對反應腔體的加熱及其溫度的精確測量，提供pcr擴增反應所需的溫度條件。
