If fully occupied, the two World Trade Center towers in New York City would alone generate 2.25 million gallons of raw sewage each year -- as much as a city the size of Stanford, Connecticut, which has a population

单单纽约市的二个世界贸易中心大楼如果完全被占满的话，每年就会产生 2，250，000加仑的污水。这相当于康涅狄格州的斯坦福市这

In this paper, an algorithm to achieve both two dimensional high resolution and wide swath is proposed. Every small satellite work in the active state, they transmit and receive different frequency band signal simultaneity. First, the azimuth ambiguity is eliminated in each frequency sub-band, then the signal is rectified to zero Doppler frequency, after that this algorithm does the range spectral synthesis to achieve high range resolution.

该文分析了一种沿航向排列分布式小卫星宽测绘带二维高分辨率成像技术，每颗卫星同时发射接收不同频率的线性调频信号，先分别在每个子带解方位多普勒模糊，并将方位多普勒中心频率调整至零频，然后在距离向进行子带拼接得到大带宽的线性调频信号从而得到高的距离向分辨率。

Methods: Response surface methodology was applied to study effects of extraction temperature, ethanol concentration, extraction time and solid to liquid ratio on extraction yield of anthraquinone and stilbene glycoside as well as clearance rate of the extracts to DPPH radical.

通过单因素和中心组合试验，对影响何首乌中二苯乙烯苷、蒽醌类化合物含量的提取因素（温度、酒精浓度、时间、料液比）进行了研究，同时将提取物清除DPPH自由基的能力作为考察指标，运用响应面分析法确定清除自由基组分提取的最优化工艺条件。

Wormholes known as Schwarzschild wormholes are theoretical bridges between areas of space that are thought to be found in the center of a black hole and white hole, joining two universes.

以Schwarzschild虫孔闻名的虫孔被认为是黑洞和白洞中心发现的空间区域之间理论上的桥，连接二个宇宙。

By focusing on the coupling of water and fertilizer and using all-purpose regression design with four factors and five levels, and based on pot experiments and quantitative analysis, the coupling effect of water and fertilizer on Casuarina equsetifolia biomass was studied in order to solve the inconsistency problem of water and fertilizer supply on coastal sandy land.

针对滨海沙地因水肥不协调而形成大面积低效林分的问题，以水肥耦合为中心，以1年生木麻黄幼苗为研究对象，采用四因子五水平二次通用旋转组合设计，利用盆栽试验和定量分析的方法，研究探讨了在不同水肥条件下，水、N、P、K四因子对木麻黄生物量的影响。

Response surface analysis(central composite design of uniform precision) was applied to optimize the significant four factors[the ratio of bran and soybean meal,(NH4)2SO4, NaNO3 and KH2PO3] for culture medium of Aspergillus terreus by researching the contributiveness of factors and their interactions to the enzyme activity of acidic proteinase.

用响应面分析法（采用中心组合一致精度的设计）对影响土曲霉产酸性蛋白酶固态发酵培养基的4个主要影响因素（麸皮与豆粕比例、硫酸铵、硝酸钠、磷酸二氢钾）进行了优化，考察了各因素及其交互作用对酸性蛋白酶酶活的影响。

The development will require a certain level of flexibility in terms of its design, construction and operation to accommodate large events and experimental workshops. 'Darat King Abdullah II' will arrange local community events and become the cultural hub for artistic programs and activities.

为了能适应大型的活动和实验研讨会，&达拉特国王阿卜杜拉二世&将安排当地的社区活动，使其成为艺术与活动的中心。

For two decades before Loma Linda opened the world's first hospital-based proton center in 1990, standard x-ray radiation therapy was one of the standard methods for treating prostate cancer.
