In plotting scene, the invention connects fiber-optic gyro(1) with full station instrument telescope(3) by adaptor(2), and make optical fibre gyro can follow full station instrument telescope simultaneously do 180 degree turning reel full station instrument cross shaft, respectively on two horizontal positions of east and west direction of gyro axis that differ by 180 degree; each horizontal position process 2 x 2 position gyro data acquisition on full station instrument perpendicular tray that differ by 180 degree; using formula to count out full station instrument collimation axis true azimuth, survey station meridian convergence angle, then can obtain full station instrument collimation axis grid azimuth, realize full station instrument orient.

基于光纤陀螺的全站仪组合定向方法是一种应用于测绘工作的基于光纤陀螺的全站仪组合定向方法，该方法在测绘现场，把光纤陀螺(1)通过连接装置(2)与全站仪望远镜(3)固连，使光纤陀螺(1)可随全站仪望远镜(3)绕全站仪横轴(4)同步做180度转动，分别在陀螺轴东西向相差180度两个水平位置，每个水平位置在全站仪竖盘相差180度的两个竖直位置进行2×2位置陀螺数据采集；利用公式算得全站仪视准轴真方位角、测站子午线收敛角，即可进一步获得全站仪视准轴坐标方位角，实现全站仪定向。

AIM and METHODS : Immunohistochemical technique in combination with a computer assisted TV-image analysis system were used to measure the expression level of c-erbB-2 and bcl-2 proteins in 37 cases of lung squamous carcinoma and 48 cases of lung adenocarcinoma identified pathologically. The expression of c-erbB-2 and bcl-2 genetic proteins in lung carcinoma and some image signs of invasiveness of lung carcinoma were analysed correlatively.

摘 要 目的和方法：利用免疫组化技术LSAB法和计算机图像分析系统的结合，测定经手术病理证实之37例肺鳞癌及48例肺腺癌组织中c- erbB -2及 bcl -2基因蛋白的表达水平，分析其表达或共表达与反映肺癌侵袭力的影像征象的关系。

By calculating the current-current propagator of the model G/H=SU(2)_L×SU(2)_R/SU(2), it is found that the pure gauge fields on coset space contribute only a perimeter law factor which has no influence on confinement properties of the system.

具体计算了陪集G/H=SU(2)_L×SU(2)_R/JU(2)模型的流-流传播子，发现陪集空间纯规范场只提供一个线度律因子，不影响物理系统的禁闭性质。
