In fact, you 'll rarely ever find a site that uses between one and twenty SSIs; most sites either avoid them entirely ( that's a big zero ), or use them like crazy. 事实上,您将很少发现一个站点使用1到20个SSI;大多数站点或者完全避免使用SSI(一个都不会用),或者疯狂使用SSI。
But from an economic point of view, I 'd suggest that we call the decade past the Big Zero(BZ). 然而从经济角度讲,我建议将过去10年起名为“大零蛋年代”。
Unemployment has fallen from a peak of 13 per cent to less than 6 per cent, with effective rates in Moscow and some other big cities close to zero. 俄罗斯的失业率已从13%的峰值下降至6%以下,而在莫斯科和其他一些大城市里,实际失业率接近于零。
The correction difficulty of environmental temperature, uncertainty and randomness of additional differential pressure of measurement, unstability of actual measurement, easy to drift by big margin and frequent check of zero position etc. problems of differential pressure water level gauge were analyzed. 分析差压水位计环境温度修正难点、测量附加差压的不确定性和随机性、实测不稳定、易大幅度漂移、0位必须频繁核对等问题。
In the low permeable groundwater aquifer, the diameter r_w of big well cannot be simplified as taking to zero. This makes the well discharge problem complicated. 在某些渗透系数低的潜水含水层中,大口径井的井径rw不能概化为零,这就使其井流问题复杂化。
