Will hold the post of mottled bamboo from the doctor that invites major socially, website day visits a quantity to achieve hundreds IP, the server space discharge of hire is insufficient, visit rate is very slow, do not have method, be forced to buy oneself independent server, half an year went, visit quantity increases ceaselessly, increased a server again act against one's will, invite the relevant personnel such as net canal, technology, customer service at the same time, and at this moment the income that my website did not bring one article money for me, still threw several yuan instead.

从社会上聘请专业的医师来任斑竹，网站日访问量达到数百个IP，租用的服务器空间流量不够，访问速度非常慢，没办法，只好购买自己的独立服务器，半年过去了，访问量不断增加，不得已又增加了一台服务器，同时聘请网管、技术、客服等相关人员，而这时我的网站没有为我带来一文钱的收入，相反还投入了数万余元。

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。

"I also think we should take a look at the tax portion of the stimulus package, take a look at reducing the middle class tax rate," he said.

The death rate grew by 37%. Chinese previously did not need security door. But by now, to some place, security window has been set at seventh floor. For there are too many gangster every where, no company in China would arrange with their workwomen to go home at night. No body knows what really are the food every one have everyday. Neoteny has take place on children. Then we can imagine the situation of our health in the future. There are about 20 million girls in China are pursuing sexual work. That creates 6% of GDP aggregate, which is as much as 1000 billion RMB. This kind of activity had never appeared in the history of human being except Japan. The height of Chinese people is 2.5cm lower than that of Japanese. We can no longer see them by looking down. The small Japan became big Japan. We create 0.1 billions GDP with the payment of 1 person's life, reported by reference news. The number of death in 2003 is 136 thousands. So the number of industrial injury will be 200 thousands. It is true that our GDP is bloody. Actually, this number is a small part of the true number. The numbers which can be accounted are in nationalized business or in a big accident. In personalized business or overseas-funded enterprise, the owner do not pay attention on the death of workers. So the data can not pass to the statistical department. However, the number of death there is much more than that of the first ones. If we add this in account, the number,annually can be compared with the massacre in Nanjing.

中国人从原来不知道防盗门窗为何物，到现在防盗窗已安装到了楼房的七层以上；由于流氓遍地防不胜防，全国企业早已不再安排女工上下夜班；有毒食品已经100%的覆盖了全部行业，每天人们咽进肚子里的食物究竟是什么，只有天知晓；性早熟现象已经蔓延到了学龄前儿童，未来的身体和寿命可想而知；约2000万少女被迫卖淫，创造的收入占GDP总量的6%，相当于一万多亿人民币，这种肉体积累是世界历史上除日本之外绝无仅有的现象；中国人的平均身高比日本人低了2.5公分，由以前低头看日本人到现在抬头看日本人，小日本真的成了"大日本"；《参考消息》报道，中国每亿元GDP工伤死亡1人，2003年死亡达13.6万人，以此推算，今年工伤死亡人数将达到20万，"是名副其实的带血GDP"，其实这个死亡数字不过是冰山一角，能够统计到的死亡数字，要么是国有企业，要么是死人较多的特大事故，私企和外企平常死个把人根本到不了统计部门，而私企和外企用工数量远远超过国有企业，如果考虑到这个因素，每年死亡人数至少相当于一场南京大屠杀。

Results showed diural variations of leaf Pn displayed bipeaked curve model, indicating the depression of photosynthesis at noon. Leaf Pn rate in June was higher than in September; Compared to leaf Pn, Cs had a similar changing curve, Cs in June was higher than in September. While diural variations of intercellular CO2 concentration were opposite to that of leaf Pn and Cs, decreased before 1200,increased after 1200, decreased again at 1600,after 1600 increased again; diural variations of climatic factors displayed single peaked curve model, peakedvalue occurred at 1400,and their influences on physiological factors were indirected and integrated.

结果表明，光合速率的日变化具有双峰型，存在光合午休现象，6月的光合速率高于9月；沙棘的气孔导度较低，其日变化与光合速率有相似的变化趋势，6月的气孔导度大于9月；细胞间CO2浓度的日变化与光合速率和气孔导度的日变化相反，1200之前下降，之后上升，1600下降，然后上升；气象因子的日变化具有单峰型，峰值1400出现，对生理因子的影响是间接且综合的。

Reactive oxygen species causing DNA oxidative damage comes from two kinds of ways:one is from cellular normal physiological metabolism;the other is from outer environment.Redox-sensitive green fluorescent protein was expressed in Saccharomyces cerevisiae.Recombinant cells were evaluated in monitoring the changes in the redox state of living cells when challenged with toxicologically relevant metal ions NaAsO_2 or Pb(NO_3)_2 by measuring emission intensity at 510 nm with a Hitachi F6500 fluorescence spectrophotometer,roGFP expressed in yeast responded not only to typical membrane-permeant oxidants H_2O_2 and reductants DTT,but also to toxicological metal ion-induced intracellular redox changes in a dose-dependent manner.Moreover,exposure of yeast cells to NaAsO_2 or Pb(NO_3)_2 at concentrations that induced redox changes reported by roGFP caused up to 2～3 fold increases in DNA mutation frequency.This mutagenic effect was largely caused by oxidative stress since blocking the production of hydryl radicals with thiourea significantly reduced the mutation rate as well as delayed the cell death.

本文将对氧化还原状态变化敏感的绿色荧光蛋白roGFP1-R12，在酵母细胞中实现了多拷贝强表达；荧光扫描经强氧化剂H_2O_2和还原剂DTT以及环境中重金属NaAsO_2或Pb(NO_3)_2处理后的酵母细胞悬液，测定510 nm处的荧光发射强度结果显示，表达的绿色荧光蛋白对氧化还原水平敏感，且在510 nm处的荧光强度与一定的重金属浓度呈正相关，即roGFP1-R12在510nm处的荧光发射值随重金属浓度的增高而增强，从而说明重金属对细胞的毒性在一定程度上很可能是通过破坏细胞内的氧化还原平衡发生作用；同时通过该绿色荧光蛋白对胞内氧化还原状态变化的响应情况可以来实时检测环境中的重金属；遗传学的点突变频率及致死率实验数据表明，重金属能导致菌体的点突变频率和致死率升高，且活性氧的清除剂巯基脲能明显降低这种点突变和致死率，说明由重金属引发的这种点突变和致死效应在很大程度上是依赖于重金属对细胞诱导产生的氧化胁迫。
