Meanwhile, the concentration of Pb,Zn and other heavy metals is rather high in the oxidation zone and decreasesdownward to levels that are unbelievably low for Pb-Zn mine tailings. Theseobservations suggest that heavy metals should be re-immobilized by secondaryminerals, rather than primary minerals, in the oxidation zone, and could be leachedout from suboxic environment due to low rate oxidative dissolution which preventsthe precipitation of secondary minerals in significant amount. Thus, cover scenarioswhich establish a suboxic environment beneath the cover layer might not always beeffective in preventing heavy metal release from mine tailings.Sequential extraction studies indicate that, in addition to heavy metal leaching,oxidation of the mine tailings increased the mobility of residual Zn, and Cu, while Pb remains immobile due to the formation of anglesite (PbSO4). Using the seven-step extraction technique developed by Dold (J. Geochem. Explor., 2003, 80: 55-68), galena dissolves in significant amount at step 2 most probably due to the strong complexing of Pb2+ by acetate, while other metal sulfides dissolve at step 6, which suggest that this extraction technique could not be used to evaluate the mobility of lead in natural environment

重金属含量均低于新鲜尾矿，但以硬化层中的含量最高(Pb、Zn含量分别为0.47%和0.93%)，往下大幅度降低，表明尾矿风化过程中形成的次生矿物对Pb、Zn等重金属元素有较强的固定作用，而次氧化带的淋溶作用造成了金属元素的大量流失；(4)与新鲜尾矿相比，硬化层中铅的可迁移性大大降低，硬化层之下尾矿样品中铅的可迁移性也不同程度降低，这是由于硫化物氧化产生的硫酸根与尾矿中的铅反应形成铅矾(PbSO_4)的缘故；(5)氧化作用使尾矿中的zn、Cu等重金属的可迁移性不同程度地增大，其中对锌的可迁移性影响最大，铜的可迁移性与铁比较相似，铅则容易与硫化物氧化形成的SO_4~(2-)反应形成铅矾(PbSO_4)；(6)为了减少尾矿污染和修复矿山环境，人们提出了各种不同的尾矿覆盖方案，本文的研究结果表明，这些方法不一定能够有效地阻滞污染元素的迁移。

In control group(n=38) the patients were given aminophylline tablets in addition to common antiphlogistic nebulization treatment;while in treat group(n=42) the aminophilline load were applied to assist the common antiphlogistic nebulization treatment.results in comparison with control group,the patients in treat group were more fastly liberated from asthmatic couphing and dyspnea(p.05),needed fewer days in hospital(p.05) and had an elevated cure rate(p.05).conclusion aminophylline load application as the assistant way is an effective,safe and economical method to fastly alleviate the dyspnea caused by bronchiolitis.

Food and beverage industry in Nanjing district attendants about the basic wage 900-1200 this way, but what are you going to look at specific industries, if large-scale hotel, the staff are generally corkage fee, which is a considerable revenue to those small hotels wages will naturally lower, Hengtong is signed, the general three-month trial period, and then give you three months after the conversion as to raise wages, the average down the catering industry in Nanjing Attendants wage level in 1000 is probably about money, but for the occupants to eat, in addition to a monthly twenty or thirty dollars to pay the cost of utilities.

在南京市区餐饮行业服务员的基本工资大概在九百到一千二这样子，不过要看你干什么具体行业了，如果到大规模的酒店里，服务员一般都有开瓶费的，这也是一笔可观的收入，到那些小型饭店工资待遇自然要低一些，恒通是要签的，一般试用期三个月，然后三个月后给你转正工资也随着提高，平均下来南京地区的餐饮业服务员工资水平大概就在一千块钱左右，不过是供吃供住的，除了每个月要交二三十块钱的水电费。

John Ringwalt's homestate operation now consists of five companies, with Kansas Fire and Casualty Company becoming operational late in 1977 under the direction of Floyd Taylor. The homestate companies had net premium volume of $23 million, up from $5.5 million just three years ago. All four companies that operated throughout the year achieved combined ratios below 100, with Cornhusker Casualty Company, at 93.8, the leader. In addition to actively supervising the other four homestate operations, John Ringwalt manages the operations of Cornhusker which has recorded combined ratios below 100 in six of its seven full years of existence and, from a standing start in 1970, has grown to be one of the leading insurance companies operating in Nebraska utilizing the conventional independent agency system. Lakeland Fire and Casualty Company, managed by Jim Stodolka, was the winner of the Chairman's Cup in 1977 for achieving the lowest loss ratio among the homestate companies. All in all, the homestate operation continues to make excellent progress.

John Ringwalt 负责的 Homestate 业务旗下主要包含五家公司，其中堪萨斯火险在 Floyd Taylor 筹备下于1977年底正式营运， Homestate 1977年的保费净收入达到2，300万美元，三年前不过只有550万美元，其余四家的年度综合比率都低于100，其中 Cornhusker 甚至只有93.8， John 在努力管理其它四家公司的同时，更让 Cornhusker 过去七年有六年的综合比率低于100，从1970年正式营运以来，该公司已顺利成为内布拉斯加州传统独立经纪系统的领导业者，至于由 Jim Stodolka 带领的 Lakeland 火险则荣获1977年主席杯的头衔，因为去年该公司的综合比率最低，总的来说， Homestate 集团的营运在去年大有进展。

在之后的两百多年间，罗塞塔石碑仅曾短暂地离开过大英博物馆一次——1917年时，接近尾声的第一次世界大战战火蔓延，由于博物馆方面担心伦敦遭受到激烈的轰炸而损伤古物，因此将一批包括有罗塞塔石碑、较为轻便容易搬移的重要古物，偷偷藏匿在霍本一带深达地下50英尺的地下铁车站中，为期两年。直至大战结束恢复和平后，才将古物移回博物馆继续展览。不过，并不是全世界的人们都很乐意见到罗塞塔石碑被保存在大英博物馆中，例如设址于开罗的埃及古物最高委员会（Supreme Council of Antiquities，是埃及文化部的下辖组织之一）主秘、也是知名埃及考古学家的札希·哈瓦斯博士（Dr。 Zahi Hawass）就曾公开呼吁英国应该将罗塞塔石碑归还给它真正的归属地、埃及，因为这块石碑是埃及文明的重要象征。
