attitude of rocks

用法例句

Due to determining the rock mass formation attitude is difficult and easy to create big error when using compass and hang compass at present,design the instrument of determining rock mass formation attitude and give the usage.

通过目前矿山岩矿层产状测定工具罗盘、挂罗盘测定岩矿层产状困难和测定值误差较大,设计出矿山岩矿层产状测定仪(尺),介绍其如何使用,其测定值精度高于罗盘13~25倍,并将罗盘测定岩矿层产状必须在岩矿层层面上,改变为只要有岩矿层层面线即可,克服了不好找岩矿层层面和岩矿层层面不规则等困难。

The attitude of blind rocks can not be calculated in terms of point of intersection of small circles in steregraphic projection net when small circles don t intersect.

根据通用地质坐标系的理论和方法,提出了求地下岩层产状的“最短捷径跟踪法”(简称跟踪法),解决了在单个弯曲钻孔中用“小圆交点法”求解岩层产状时,由于测量误差或岩层产状的微小变化而产生的小圆不相交的问题。
