quartz sample

Type D has only one sample, which comes from the metamorphosed arkose sandstone. coarse to fine-grained quartz-syenite;

D型是变质的长石石英砂岩。

In order to construct a new type of piezoelectric quartz crystal DNA biosensor for HBV, the single-chain DNA sequence is immobilized on the surface of gilt quartz crystal to make a HBV gene sensor, then to hybridize on the gene sensor in the serum sample.

为了建立石英晶体DNA传感器检测乙肝病毒基因的方法，在石英晶体金表面固定单链DNA，构成压电晶体HBV dna生物传感器，与待测样品进行杂交反应。

Non optical methods of sample tip distance regulation based on shear force which include emission detection with PMT, quartz tuning fork, capacitance, piezoeffect, impedance are reviewed in this paper.
