In terms of age distribution, male overweight and obesity rates were from the 20-year-old age group starting with age increase, the highest in the 30-34 years of age, then decreased in 30-39 years of age, followed by changes in body weight without apparent regularity; female overweight rates always raised with age increase and declined from the 50-59 age group.

从年龄分布来看，男性超重率和肥胖率均从20岁年龄组开始，随年龄的增加而增加，在30~34岁达到最高，到30~39岁年龄段有所下降，之后体质量变化无明显规律性；女性超重率随着年龄的增加始终呈现上升趋势，到50~59岁年龄段又有所下降。

Based on the radar dense data of convectional cloud on June 12,2004 in Yongdeng county,choosing two similar convectional clouds as seeding and non-seeding cloud,the remarkable changes of radar echo parameters of the seeding cloud compared with the non-seeding cloud were discussed in this paper,and the rain enhancement effect was evaluated primarily with ground observational rainfall data.The results show that many aspects of the seeding cloud,such as precipitation,life characteristic and vertical characteri...

利用2004年6月12日甘肃省永登县雷达观测对流云的加密资料，选取了2次相似对流云过程分别作为目标云和对比云，探讨了目标云作业前后较对比云雷达回波有关参数的显著变化，并结合地面雨量点观测资料对地面人工增雨作业效果进行了初步分析，结果表明：目标云在降水、生命期特征、回波垂直特征参数变化方面，表现出作业前后较对比云存在明显差异，目标云作业40 m in后地面产生0.6 mm降水，而对比云则从新生发展到减弱消散阶段经历较短的时间(30 m in)，地面并无降水产生，从而推断本次人工增雨达到了一定的预计效果。

Seepage velocity smoothly change from a steady value to a new steady value, the ratio of the new steady value over the original steady value might increase hundreds of thousand times or even more, but it is always finite.（3）Water-inrush goes with the failure of rock strata, but seepage velocity can not increase unendingly, so seepage flow cant be unstable.

研究表明：由于非Darcy流β因子恒为正值，渗流系统总是稳定的；当渗透特性随时间变化时，渗流速度从一稳定值平滑地过渡到一新的稳定值，新的稳定值与原稳定值之比可以增大到几万至几百万倍，但是总是有限的；突水是岩层结构破裂引起的渗流速度快速或急剧变化，但渗流速度不可能无止境地增大，即渗流不可能失稳。

According to the above-mentioned experiments, the study select discriminable data which form discriminant function and make discriminant analysis on the objects (students from junior Grade Two and senior Grade Two, with academic achievements ranging from excellence, ordinariness, to failure) with ten members in each group, which leads to a discriminant system of middle school students with different academic achievements.Ⅳ.

As for the quantity and scope of the literary quotation used,he has overpassed the writers at that time and grand old mans. As for the state of literary quotation in the poems,they are assimilated by Xin into his own poems,and can hardly distinguish where they are from. As for the motivation of using the literary quotation,Xin is not only for using them,but for building better bourn and expressing the emotion. As for the methods,Xin always use them skillfully to meet different purpose with transfer,direct use and adduction.

稼轩词用典，从数量和广度上说，他广采博收，数量之多，范围之广，远超时贤及前辈；从典故在词中状态而言，浑成脱化，全如己出，同时又雅俗一体，关合无迹，如水中着盐不着痕迹；从用典的目的性而言，稼轩不是为用典而用典，而是为了更好的铸造境界、传达情感；从用典的方法看，稼轩词腾挪变化，根据不同需要或化用或移用或明用或暗用，皆能曲尽其妙。

Leakage in the initial observation to determine the basis of the leakage site, and then manually set car observation, if the leakage were no significant changes in static and dynamic sealing ring problem; such as the disk when there are significant changes in leakage can be concluded that the dynamic , static friction ring problems; such as leakage of medium along the jet axis, while moving most of Central ring problems, leakage to the surrounding medium or from the water spray cooling holes in the leakage, the seal ring for static failure.

在初步观察泄漏量、判断泄漏部位的基础上，再手动盘车观察，若泄漏量无明显变化则静、动环密封圈有问题；如盘车时泄漏量有明显变化则可断定是动、静环摩擦副存在问题；如泄漏介质沿轴向喷射，则动环密封圈存在问题居多，泄漏介质向四周喷射或从水冷却孔中漏出，则多为静环密封圈失效。
