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 conceptions of the superiority, inferiority and equipollence position degrees of the interval grey number were defined, and it was proved that the sum of three position degrees for a certain interval grey number related to another grey number is 1, and that the relation set of the position degrees is a whole order set of the interval grey numbers.

运用灰色系统思想和系统工程的理论,揭示了人们在灰信息条件下的博弈心理与博弈决策规则;提出了区间灰数的优势、均势和劣势的概念;证明了与某一区间灰数相对的另一区间的各种灰数势之和为1,且灰数势大小关系的集合是一个全序集。

Results show that, following the leaching time extending, the leaching concentrations of heavy metals and lixiviate toxicity of heavy metals increase in the fly ash. When the ratio of liquid and solid add, the leaching concentrations of heavy metals obviously become big, and the Cd's leaching concentration is the biggest, when the ratio of liquid and solid is 90, the Cd's leaching ratio exceed the percent of 70. At the time pH is about 7, the leaching concentrations of heavy metals are the lowest. When the grain size is the bigger or little, the leaching concentrations of heavy metals are lower, however when the grain size is 250-900 μm, the concentrations are higher. After fly ash melt in the high temperature, the lixiviate toxicity of heavy metals greatly reduce, which explains that the effect of melting on heavy metals' stabilization is very good.

结果表明,随着浸出时间的增加,飞灰绝大部分重金属的浸出浓度增高,浸出毒性增强;液固比增加,大部分重金属的浸出率大大提高,其中重金属Cd的浸出率最大,在液固比为90时,飞灰中的Cd的浸出率达到70%以上;pH为中性左右的时候,医疗垃圾飞灰中的大部分重金属的浸出液浓度最低;颗粒尺寸在较大或者较小时,医疗垃圾飞灰中的大部分重金属浸出浓度较小,大部分重金属在颗粒尺寸250~900 μm时,重金属的浸出浓度较高;飞灰高温熔融后,重金属的浸出毒性大大降低,说明熔融对重金属有很好的固化效果。

In this text, on the base of gradation design, the pavement performances of lime-fly ash stabilized aggregates and lime-fly ash mortar under controlling fine aggregates gradation are studied, and contrasted with the mixtures which are under uncontrolling fine aggregates gradation, including mechanical performance, stableness, anti-brushing performance, the anti-crack performance, and drawing the conclusion of controlling fine aggregates gradation.

在配合比设计的基础上,研究了控制细集料级配的二灰砂浆和二灰碎石混合料的力学性能、稳定性能,以及二灰碎石的抗收缩性能、抗冲刷性能,并与不控制细集料级配的二灰砂浆和二灰碎石混合料的路用性能进行了对比,得出实际施工中应控制细集料级配的结论。

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。

Lanzhou Worker Du Weicheng inherits the ash bean famous expert horse to have the formulation ash bean soup make technique, the make ash bean soup flavor is unique, in 1989 is awarded Du Weicheng by the Gansu Province commercial hall by "the Jin Cheng ash bean king" the title.

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。

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.
