n.测面器；求积计
The surface ratio of conus to disc was calculated using a planimeter. 我们使用面积计测量圆锥与视神经盘表面比值。
Graph paper, parallel, and planimeter methods are current tools for acreage calculation. 目前常用的量算面积方法有方格纸法、平行线法、求积仪法。
The method resolved the defects caused by common methods with planimeter on calculating area, which produce low... 目前此方法已在生产中进行了推广应用。
An integrating mechanism based on the principle of the planimeter is suggested. This instrument may be used to determine the mean height of a curve. No calibration is required. 根据面积仪原理,提出可以利用无刻度的积分机构直接求出底线不太长的曲线的平均高度,如拜氏织维图中的织维平均长度。
In traditional reservoir capacity calculation, a planimeter is used to obtain a reservoir capacity from topographic maps and large scale topographic maps are needed if high accuracy is required. 传统的库容计算方法是在已有的地形图上采用求积仪法进行，当精度要求较高时，需到现场实测更大比例尺的地形图。
