平方公尺

At ground level, this 20,000-square-foot garden—created in 1995 by landscape architect Cornelia H. Oberlander—would be striking enough.

就算只是在地面，这座1995年由景观设计师柯妮莉雅奥伯兰德设计、面积1850平方公尺的花园，也够引人注目了。

Furthermore the performances of heat transfers including corrugate plate, tube and fin-tube were compared under the same conditions. The results show that when the air frontal velocity is between 2.45 and 4.1m/s, the overall heat-transfer coefficient of plate heat exchanger ranges from 100 to 160 W/m^2/ equal to one sixth of that of fin- tube cooler based on tube outside area, which is about 70% higher than that of tube cooler. The volumetric heat transfer capacity of plate cooler is 1.5 times as that of fin-tube cooler and 15 times as that of tube cooler. The heat transfer capacity of per unit power of plate cooler is 5.5 times as that of tube cooler and similar results for fin-tube cooler.

在相同工况下，比较了波纹板式、光管式和翅片管式空冷器的性能指标，结果表明：迎面风速在2.45~4.1m/s之间，波纹板式空冷器传热系数达到100~160W/平方公尺/℃；约比光管式提高70%，但只有以管束外表面为基准的翅片管式传热系数的六分之一；板式空冷器单位体积换热量约是翅片管式空冷器的1.5倍，是光管式的15倍；板式空冷器单位功耗换热量约是光管式空冷器的5.5倍，而翅片管式空冷器与光管式空冷器则相差不大。

In a home with only some 33 square meters of floor, the living room must serve double-duty as a study. The children study at this table, and here display their awards for scholarship, in prominent view. These are the household treasures. In a nearby room lies their sick father; stricken by a brain tumor, he is now a quadriplegic.

家里不到33平方公尺大，客厅就是书房，姊弟两人在这个桌上读书，墙边贴著满满的奖状，这是家里最珍贵的物品，客厅另一头是生病爸爸的房间，爸爸罹患脑瘤四肢也萎缩无法动弹。

If they are not recycled properly, one dry cell battery buried in the soil is able to make a square meter of soil permanently unusable.

若没好好回收，一颗乾电池若埋在土里将能使一平方公尺的土壤永久失去利用价值。

The Pd-Cu/C catalysts were shown to have the face centered cubic crystal structure. This could indicate that the addition of Cu shortened the Pd-Pd distances in the crystal lattice, and therefore –HO(subscript 2ads) and O-O could be better adsorbed on the surface of the catalyst. When NaBH4 was used as the reducing agent, and the atomic ratio of Pd to Cu was 3:1, the resulting catalysts had an average particle size of 3. 4nm and showed the best catalytic performance. The electrochemical active surface are a of Pd3Cu/C was 38.9m^2/gPd and the oxidation reduction reaction activity of the Pd3Cu/C catalyst was much higher than that of the Pd/C catalyst. The electrochemical activity of the Pd3Cu/C catalyst was comparable to that of a commercial Pt/C catalyst.

结果表明：催化剂中Pd与Cu的物质的量之比与预设值相近，Pd和Cu基本被全部还原；Pd-Cu/C催化剂为面心立方结构，元素铜的加入使催化剂的Pd-Pd间距缩小，从而HO(下标 2 ads)和OO键能更好地吸附在催化剂金属表面；当采用NaBH4为还原剂，Pd与Cu物质的量比为3：1时，催化剂(Pd3Cu/C)的平均粒径为3.4 nm，催化剂的催化性能最好，电化学活性表面积EAS达到38.9平方公尺/gPd，电化学性能较Pd/C催化剂有很大提高，接近Pt/C商用催化剂。

The Divine Mercy basilica dedicated to Saint Faustina was built at a cost of US$7.5 million from donations by faithful followers all over the world. The basilica has two-levels and an area of 1,500 square meters. It has the shape of a boat on the outside.

献给佛斯蒂纳圣女的神圣慈爱教堂，耗资七百五十万美元，由全球信徒捐助兴建完工，占地一千五百平方公尺，外型像一艘船，是一座两层楼的教堂。

The results showed that at the conditions including using 3 mol/L ZnCl2 as activator at 550 with the ratio of solid to liquid as 1: 2.5 for two hours of pyrolysis time, the iodine adsorption capacity of prepared activated carbon was 317.4 mg/g, and the specific surface area was

结果表明以3 mol/L的ZnCl2为活化剂，活化温度为550℃，固液比为1：2.5，热解时间2 h，制备的活性碳吸附剂吸附碘值为317.4 mg/g，活性炭吸附剂比表面积为232.526平方公尺/g。

At the present time, for example, the mixed vessel with a screw is a surprising machine, propelled by three thousand square metres of canvas and by an engine of two thousand five hundred horse-power.

到今天，比方说，一条机帆两备、具有螺旋推进器的船，那真是一种骇人的机器，它的帆的面积达三千平方公尺，汽锅有二千五百匹马力。

And the results show that perfect heat-treatment time is two hours. The specific saturation magnetic moment of 26.2A m^2kg^(-1) is obtained.

The modified method can satisfy the limit of mean square deviation within 10W/m^2, and the average relative error is about 25%.

计算结果与西沙实测资料、长年代的GSSTF2资料和NCEP/NCAR再分析资料进行比较验证，证明改进后的方法精度较高，基本可以保证湍流热通量的平均标准偏差在10W/平方公尺左右，与多年的月平均做比较，相对偏差为25%左右；同时，不仅首次将计算热通量的空间尺度精确到0.1°×0.1°，而且基本模拟出了南海季风暴发期间热通量变化的主要特点以及中国近海热通量随季节、纬度和海岸地形的变化特征。

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。
