商业指标已经稳定下来,但这仅仅表示经济有可能在该季度以同样的速率下滑,并不是表明下降的趋势已经停止。
Business indicators have stabilised but this suggests only that the economy is likely to shrink at a similar rate in the current quarter, not that activity has stopped falling.
其中,速度表示星系后退的速度,H0为哈勃常数,也即宇宙膨胀速率的参数,而距离指的是星系与相比较星系之间的距离。
H0 is the Hubble constant, or parameter that indicates the rate at which the universe is expanding; and distance is the galaxy's distance from the one with which it's being compared.
根据它的原理,我们通常用v表示,这里的V更代表速率而不是矢量,你能通过,对一个关于时间的位置向量求导得到它。
And, the way we can get it, so, it's called usually V, so, V here stands for velocity more than for vector. And, you just get it by taking the derivative of a position vector with respect to time.
It's how fast they adjust to the target.
表示着向目标调整的速率
