后静压头已足以降低，甲烷气体会流向地面。

After the hydrostatic head has been sufficiently lowered , the methane gas will flow to the surface .

本文建立了静压头、雾化压力与雾化熔滴尺寸的模型关系。

The relationship model of static head in tundish , atomization pressure on the tip of nozzle and the mass median droplet diameter was established .

还有，床层中任意两点间的压差大致等于这两点间床层静压头。

Also , the difference in pressure between any two points in a bed is roughly approximated by the static head of bed between these points .

试验结果表明，在考虑的工艺因素中，对充型速度的影响由大到小依次为：模样材料、金属静压头、涂料透气性和浇注温度。

The results show the relative importance of factors , from most significant to least significant : foam material , metallostatic head , the permeability of the coating , pouring temperature .

通过模型，调节雾化压力以适应静压头变化引起的金属液体质量流率变化，以期得到具有合适尺寸的雾化熔滴，优化沉积坯组织。

In order to get good quality preform , the change of metal flow rate caused by the change of static head was adjusted by altering the atomization pressure by this model .

文章采用流体静压头下降成比例的测量方法，记录其流动时间，简便地解决了幂函数求解指数的显函数方法。

In light of the measure way of fluid static pressure falling in proportion , the explicit function method of solving exponent by power function was simply and conveniently acquired through recording fluid flowing times .

雾化压力一定，雾化熔滴质量中值直径随静压头的减小而减小；静压头一定，雾化熔滴尺寸随着雾化压力的增加而减小。

The mass median droplet diameter will decrease with reducing static head when the atomization back pressure is a settled value ( the atomization pressure does not change ) and with increase of atomization pressure ( static head is constant ) .
