Matre Andry looked up, appeared to calculate for a moment the height of the pillar and the weight of the little rascal, mentally multiplied that weight by the square of the velocity —and held his peace.

安德里老公抬起眼睛望了一会儿，好像在估量一下柱子有多高，促狭鬼有多重，再默算一下重力乘加速度之平方，然后不敢作声了。

The results show that the perfect Honeycomb pattern films without defects within area of 0.8cm^2 can be obtained at the PS concentration ranges from 20 mg/mL to 50 mg/mL and PS/TEOS mass ratio less than 2. The films cast from the chloroform solution of dicarboxyl terminated PS were more perfect than those cast from the chloroform solution of monocarboxyl terminated PS. The perfect Honeycomb structure films could be obtained with both chloroform and benzene as solvents, but the pore diameter of films cast from benzene solution of PS was larger than that of films cast from chloroform solution of PS.

研究结果表明，聚合物浓度在20~50mg/mL，PS/TEOS质量比大于2：1的条件下可以制备结构完整的多孔膜，且制备的Honeycomb结构在0.8平方公分内无缺陷；采用双羧基封端的聚苯乙烯成膜效果好于单羧基封端的成膜效果；以氯仿和苯作为溶剂均可以制备完全Honeycomb结构的复合膜，但以苯为溶剂制备的多孔膜孔径较大。

Archaeologists excavated for 5 months in the northern Greek region of Pella to uncover the base of the 58 square metre building, which was made from wooden poles, branches and mud.

A UN environmental assessment of the country estimates that productivity could be doubled on the land currently farmed, while another 10% of Afghanistan (approximately 62,000 square kilometres, or 24,000 square miles) could be brought under the plough through irrigation.

联合国的环境评估认为，如果阿富汗那10%无人耕种的土地（有将近62000平方千米，或者说24000平方里）能够被开垦和灌溉，那该国的生产力将能翻倍。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
