One-room shanties are sandwiched together, so that the densities average 250 units per hectare, versus 25 units in a middle class area and 10 units in high-income areas.

一间窝棚是夹心一起，使250个单位的平均密度为每公顷，与25个单位在一个中产阶级区和10个单位在高收入地区。

A two-times locating method based on the gray contrast of surroundings is presented in locating central reference point. This method has better adaptability and robustness, and can basically meet for the accuracy of automatic locating center. Fourier spectral analysis is improved to obtain a more accurate ridge frequency in computing ridge frequency. The average ridge width is used in designing Gabor filters, so the filters have certain adjustability. The rotating invariance of fingerprint images is solved by the rotating of feature models in feature matching.

在中心参考点定位部分，提出了基于局部邻域灰度对比度的二次定位方法，该方法具有较强的适应性和鲁棒性，基本满足自动中心定位的准确度要求；在频率域估计中，改进了傅立叶谱分析法，提高了纹线频率计算的准确度；引入平均纹线宽度作为Gabor滤波器的设计参数，使滤波器具有一定的自适应性；在特征匹配阶段，通过对特征模板的旋转解决指纹图像的旋转不变性问题。

On the basis of basically universalizing the nine-year compulsory education and eliminating illiteracy among youth and the middle aged by the year 2000, the educational sector must complete the universalization of the nine-year compulsory education by the year 2010 and universalize senior secondary education in urban and developed regions.

在2000年基本普及九年义务教育和扫除青壮年文盲的基础上，到2010年，全面普及九年义务教育，并在城镇和发达地区普及高中阶段教育，使居民平均受教育年限接近中等收入国家水平。

In the medical isotope reactor to separate and purify the medical isotope 99Mo and 131I, the reactive heat is constantly generated in the process of reaction, associated with the production of fission gas. In order to control the average temperature (usually≤80℃) of the reactor to prevent the sample from volatilizing, the cooling system of the reactor need to be designed carefully.

在使用医用同位素反应堆分离提纯医用同位素99Mo和131I时，由于反应过程中会不断产生热量并伴随裂变气产生，为了控制堆内平均温度(通常≤80℃)以使样品不致挥发，这就需要精心设计反应堆的冷却系统。

And those zeroes drop your average to a 58%.

零分使你们的平均成绩降到了58%。

On average, plantations cut local stream flow by more than 50%.

平均而言，植树使当地水流量的减少幅度超过了 50%。

Perhaps as importantly, the latest bearings also weigh up to 80% less than conventional all-steel designs, with a high strength to weight ratio that makes them suitable for design engineers looking to minimise the weight of equipment without sacrificing performance.

也许同样重要的是，最新的轴承的平均体重也达到80 ％小于常规全钢设计，具有高强度重量比，使它们适合于设计工程师期待以减低重量的设备而不牺牲性能。

deviation of the antenna radiation resistance seems larger in some textbooks about the electromagnetic theory for the editors have made some similar treatment when discussing the radiation power of short antenna.combining the concept of physical with mathematical tools and the precise results are gained,that is the real radiation resistance of electric dipole antenna is about ten times smaller than that of the approximate results in the actual literature by researching the electromagnetic field theory and average energy density.this offers evidence to grasp the radiated ability accurately.

小 摘要：在部分有关电磁场理论的教材中，编者讨论短天线的辐射功率时，由于作了某些近似处理而所得天线的辐射电阻值偏差较大。从天线辐射的电磁场理论和平均能流密度出发，使物理概念和数学工具相结合，运用矢量运算推导出精确的结果，即电偶极子天线的实际辐射电阻要比文献中的近似结果小数十倍，因而为准确把握天线的辐射能力提供了依据。
