Gravity measurement (in Microgal class) and microgravity study based on it can be carried out by using advanced Lacoste-D gravimeter. In this way，the microgravity method has got an excellent test and application in practice;it has also opened up a new branch of gravity research. At present，it is more and more important in our national economy and construction of national defence to probe into the small-scale density anomaly bodies and caves at shallow layer as well as the distribution of small-scale structures and the local heterogeneity or artificial structures in historical remains near ground. Consequently，Microgravity measurement and the analysis method on it possess particular sig- nificence and have a far-reaching prospect.
