Methods The total cantharidin obtained with acidolysis method and the free cantharidin obtained with direct extraction method were determined in eight species of Meloidae and the control species Huechys sanguinea (Homoptera: Cicadidae) by gas chromatography, and the content of the bound cantharidin in each species was calculated with the content difference between the total cantharidin and the free cantharidin. The relationship between the contents of the bound cantharidin and the contents of Ca and Mg elements in Meloidae were assessed.

利用气相色谱法测定了8种芫菁和作为对照的黑翅红蝉体内总斑蝥素和游离斑蝥素的含量，总斑蝥素含量是通过酸水解法测得的，游离斑蝥素含量是通过直接浸提法测得的，以总斑蝥素与游离斑蝥素含量之差作为结合斑蝥素含量；并比较了结合斑蝥素与钙、镁含量之间的相关性。

We found that the mean square error of difference value between GPS monitoring deformation and the second-order leveling surveying deformation is less than 1 mm, and there is a smaller systematic error between the ellipsoidal height deformation and the second-order leveling deformation ,whose value is about 0.5~1 mm; however, this system error does not affect the outcome of vertical deformation monitoring.

结果 得到的GPS监测变形量与水准测量变形量差值中误差＜1 mm，且GPS所测大地高变形量与二等水准测得的变形量间存在一个较小的系统偏差，其值在0.5~1 mm之间，该系统偏差不影响垂向变形监测的结果。
