Queries for other projections result in an error message asking the visitor to "request a supported SRS" (that is, a spatial reference system - essentially, the projection).
对于其他投影的查询会导致错误消息，要求访问者“请求一个受支持的SRS”(即一个空间参考系统—本质上，就是这个投影)。
The crank reference pulse originates from a variable reluctant pickup which senses a projection on the engine's flywheel.
曲柄参考点脉冲信号由一个变磁阻传感器产生，它从发动机飞轮上的突起感受信号。
The neural network trained by projection algorithm with the reference error is used to approximate the desired feedforward compensation. Convergence of the tracking error is proved.
提出一种基于参考误差的投影算法来训练网络权值，训练后网络输出能逼近期望的前馈力矩，并从理论上证明跟踪误差的收敛性。
As an important part of GIS platform, spatial reference system includes coordinate transformation and map projection, also named as map projection transformation system.
GIS中的空间参照系统是GIS平台中的重要组成部分，内容包括各种坐标系统的转换和地图投影，故也称为投影变换系统。
