To improve its classification performance, the main methods were selecting the more effective distance measure.

为了提高最小距离分类器的分类性能，主要的改进方法是选择更有效的距离度量。

Similarly for a weapon of lower energy, the effective distance is less, but so also is the rate of ascent of the cloud.

同样，对于威力较低的武器来说，有效距离要小些，云的上升速度也同样小些。

Using LVDS in FPD circuit the effective distance of LCD screen with digital RGB interface will be increased by the long way.

通过在FPD链路上使用LVDS技术可使具有数字rgb接口的液晶显示屏的工作距离大大增加。

If the collecting area is in pieces, the effective diameter (the distance between the two most widely spaced pieces) can be several thousand kilometres.

Because the output of a wind turbine also tends to increase proportionally with its distance from barriers such as trees or buildings, the most productive -- and cost-effective -- turbines sit atop tall towers erected on an acre or more of open land.
