灰

The integrated development level of college students' corporeity from 1985 to 2005 was analyzed by grey assessment and grey relational models from grey system theory to provide a scientific basis for the macroscopic decision on scholastic sports sanitation in China.

应用灰色系统理论的灰评估模型和灰关联模型对1985—2005 年间我国大学生的体质综合发展水平进行灰评估和灰关联分析，为我国学校体育卫生的宏观决策工作提供科学依据。

The first method is based multi-scale decompression using wavelet theory, it extract gray feature from each channel to form feature vector, it can distinguish objects, but this method not have invariant property when object rotate.

因此随后提出了基于灰度多通道的特征提取方法，该方法是把目标灰度分成几个区段，然后在各灰度区间分别提取目标的灰度特征，形成特征向量。

To correct the variation resulting from exposure condition, an aluminum stepwedge was exposed simultaneously. By referring the image of aluminum stepwedge on each radiograph the equivalent aluminum thickness and corrected gray level intensity of the ROIs could be calculated as indicators of alveolar bone density. Nineteen specimens containing different amounts of hydroxy-phosphorite were radiographed.

用计算机测量定位投照的直接数字化牙片上感兴趣区(region of interest， ROI)的灰度，拍片时将一个铝制梯级同时曝光，根据已知的铝梯灰度和厚度推算ROI区灰度所对应的等效铝厚度和校正灰度来反映骨密度，从而校正由于投照条件差异造成的灰度误差。

If the resistance rises to the pre-set number(1245－1470Pa), the controller will send out signals, first to control the lift valve to do these operations: close the hole of the valve board to cut air current and stop filtering, and then to open the electromagnetic pulse valve to blow compressed air whose pressure is 0.5-0.7Mpa into filter bag with a short time(0.01－0.12s).

当含尘烟气由进风口进入灰斗以后，一部分较粗尘料在这时由于惯性碰撞、自然沉降等原因落入灰斗，大部分尘粒随气流上升进入袋室，经滤袋过滤后，尘粒被阻留在滤袋外侧，净化的烟气由滤袋内部进入箱体，再由阀板孔、出风口排入大气，达到收尘的目的，随着过滤过程的不断进行，滤袋外侧的积尘也逐渐增多，从而使除尘器的运行阻力也逐渐增高，当阻力增到预先设定值（1245－1470Pa）时，清灰控制器发生信号，首先控制提升阀将阀板孔关闭，以切断过滤烟气流，停止过滤过程，然后电磁脉冲阀打开，以极短时间（0.01－0.12s）向箱体内喷入压力为0.5－0.7Mpa的压缩空气，压缩空气在箱体内迅速膨胀，涌入滤袋内部，使滤袋产生变形、震动，加上逆气流的作用，滤袋外部的粉尘便清除下来掉到灰斗，清灰完毕之后，提升阀再次打开，除尘器又进入过滤状态。

Because sheet of the known that the leakage will bring the environment problems in early days the power station constructed, generally not adopt technical measure of defending seeping, the groundwater environment changed obvious influence by the ash water leakage, the paper take the ash field of JiNing Power Station as an example, through the data contrast of the plain ash field water level and water quality in the time and on the apace, expresses that the groundwater of ash field district has already suffered pollution, generally, the scope of the pollution is in 1 kilometer.

由于早期电厂建设时对灰场渗漏引起的环境问题缺乏认识，一般不采以专门的防渗措施，灰水渗漏对地下水环境产生了明显的影响。论文以济宁某电厂灰场为例，通过对平原灰场水位、水质在时间和空间上的数据对比表明灰场区地下水已遭受污染，其污染影响范围一般小于1km。

The gas-burning pulse ash-blowing vehicle of the present invention has the outside-boiler part installed to form one movable ash-blowing equipment and one set of vehicle may be used for several boilers.

本发明创造研制一种脉冲燃气吹灰车，将现用的炉外部分脉冲吹灰设备全部安装在汽车里，制成移动式吹灰装置，解决了一套吹灰系统用于多台锅炉吹灰的问题。

By adding black and some white one gets the endless varieties of grays – red gray, yellow-gray, blue-gray, green-gray, orange-gray, violet-gray.

加入黑色和些许白色，你就能得到变化无穷的灰色——灰红、灰黄、灰蓝、灰绿、灰橙、灰紫。

More fine and lighter dust particles are fetched into the upper by the upper spiral airflow, forming strong spirally ash hoop at the inside of the top gap and bringing forth the accumulation of the dust particles, then are drawn forth from the upper entrance of special dust insulator, through the lower helical groove of dust insulator, tangential admission to the dust collector from the air return mouth of the dust collector's outside.

较细较轻的灰粒，由上旋涡气流带往上部，在顶盖下面形成强烈旋转的灰环，产生灰粒的集聚，并被从特设的灰尘隔离室上部洞口引出，经过灰尘隔离室的下部螺旋槽，从除尘器外壁回风口切向引入除尘器，筒体下部与内部气流汇合，灰粒被分离而落入灰斗。
