As part of the summit, hundreds of schools across the country are signing up to the Let's Go Zero activity, aiming to become carbon-zero by 2030.
作为峰会的一部分，全国各地的数百所学校签署了“让我们走向零碳”这一活动，旨在2030年之前实现零碳排放。
There is zero evidence that any alignment of any celestial body can influence the activity of the sun as the gravitational effects of the planets on the sun are minuscule.
目前还没有迹象显示任何天体的活动可以影响到太阳的活动，因为行星引力对太阳来说是微不足道的。
Accordingly, if an interval expires with no activity, the aggregate values for that interval will be zero regardless of the activity in the prior interval. Figure 6 illustrates this pattern.
因此，如果时间间隔到期且没有活动发生，则该时间间隔的聚合值将为零，而与之前时间间隔中的活动无关。
Cost-benefit ratio criterion----No activity where the present value of net benefits is less than zero should be taken.
成本效益分比率准则——净利润现值低于零的无活力地区应该被承揽。
The count rate at the extrapolation of bias to zero varies monotonously with the anode current of phototube and tends to the activity of source as the inverse anode current approaches zero.
甄别电压外推到零时的计数率随光电倍增管阳极电流而改变，当阳极电流的倒数趋于零时，计数率趋于被测源的活度。
The count rate at the extrapolation of bias to zero varies monotonously with the anode current of phototube and tends to the activity of source as the inverse anode current approaches zero.
