First,much basic knowledge is introduced.Then,it importantly introduces my perspective : in this paper the estimations of the parameters and coefficient of contamination for the simple regression model and studied when its response variables are contaminated by another random variable sequence it discusses that the interval estimation of posterior confidence probability of parameters on coefficient of contamination by using the method of Bayes inference.

Because the affair is actually very serious, we might as well take in to analyze once;Need not to doubt first, health department and three deer companies all have already publicly admitted at least 700 ton baby's kid's milk powders be subjected to three chlorine cyanotype An pollution, have already found out an in a short time number as well, the province appears numerous babies and kids in the meantime, the Bi urine system stone calculus really is because ate a milk powder in of three chlorine cyanotype An result in, so we will ask, three deer companies admit of just have 700 ton milk powders to be subjected to three chlorine cyanotype An pollution, talk the idea of bottom may be an emergence surprised in the production of circumstance, be also say that not and intentionally add of three chlorine cyanotypes the An be this kind of chemistry product, let the public produce a kind of imagination, perhaps just individual case, the Zhao returns to product behind again check pure pollution the reason can resolve a problem, after all this be a Zhao the race brand of, it is all to be loudly appealing and protecting race brand now?
由于事情实际上很严重,我们不妨加以分析一下;首先,毋庸置疑,卫生部和三鹿公司都已经公开承认至少有700吨婴幼儿奶粉受到三氯氰胺污染,也已经查明短时间内数省同时有众多婴幼儿出现泌尿系统结石确实是因为食用了奶粉中的三氯氰胺所造成,那么我们就要问了,三鹿公司承认的只是有700吨奶粉受到了三氯氰胺污染,言下之意可能是生产中出现意外的情况,也就是说并非故意添加的三氯氰胺这种化学制剂,让公众产生一种想象,也许只是个案,召回产品后再查清污染原因就可以解决问题了,毕竟这是一个著名的民族品牌,现在不是都在大声呼吁要保护民族品牌吗?

Species richness and Pielou evenness index were used to measure species diversity. Species richness in polluted area was 32-67, while in control area it was 47-82. Pielou evenness index of tree layer was 0.1161-0.8509, while those of shrub layer and herb layer were 0.1763-0.3249 and 0.0443-0.2601, respectively. The results showed that both species richness and Pielou evenness index were influenced by the point source pollution. Species importance values showed significant differences between polluted area and control area. Dominance of different species had changed, and some species even disappeared under the pressure of pollution, indicating a process of species replacement in plant communities. Such species replacement can provide a scientific basis for species selection for restoration of human-damaged ecosystem. The natural regeneration of Quercus variabilis was insensitive to pollution, while Cupressus funebris was effected seriously.
仅在污染区中出现的物种数量远低于仅在对照区中出现的物种数量;(2)可分出4种基本的群落类型:马尾松林、柏木林、栓皮栎林和马尾松+栓皮栎林,各群落特定层次的物种丰富度指数以及Pielou均匀度指数在污染区与对照区之间存在显著差异;(3)污染胁迫下,物种在群落中的生态优势度发生了变化,反映了群落中不同物种相互替代的过程,这种物种的替代可为今后受损生态系统人为恢复过程中物种的筛选提供一定的理论参考;(4)对群落中王要物种更新的调查发现:栓皮栎林对污染不敏感;柏木林污染区与对照区幼苗数量及分布格局均有明显差异,污染条件下群落未来演替受到严重干扰。

These samples were collected along a main street across the urban area and a mountain route from foot to the top. Results demonstrate that the main magnetic minerals in the street dust are magnetite, maghaemite and haematite with some paramagnetic minerals. Plots of Mrs/Ms vs. Bcr/Bc and Xfd % vs. X ARM/SIRM indicate that the main grain size of magnetic minerals in the street dust are pseudo single domain. The results reveal that the Lanzhou city is more polluted in spring than in summer. The main pollution sources are anthropogenic activities (81.9%) and natural dust (18.1%), especially the former. The spatial distribution of pollution is controlled by the topography and weather conditions.
结果表明,兰州市街道尘埃中磁性矿物含量较高,主要磁性矿物是铁磁矿、磁赤铁矿和赤铁矿,并伴有少量顺磁性矿物;磁性矿物粒度主要是准单畴;市区污染春季较夏季严重,春季高频率的强沙尘暴可能带来了更多的磁性矿物;兰州市污染物的沉积和分布在很大程度上受到气象条件和地形地貌格局的影响,市区每个盆地东端高于其它地区;兰州市污染以人为活动产物为主,人为活动贡献约为81.9%,其中包含交通约22.6%的贡献,自然降尘贡献约为18.1%;特殊的地形和气象条件,使得兰州市区的大气环境容量比平原城市的环境容量小得多,进而导致严重的大气污染。

These dumping sites are not only harmful to surrounding ecological environment, but also threaten the health of around residents.Serious aftermath can be resulted by these refuses polluted with heavy metals in dumping sites because of being disorderly pilled. Therefore, evaluation pollution degree of heavy metal in refuses will be beneficial to perform Environmental Impact Assessment of these dumping sites and put forward measures of pollution protection.
它们不仅影响周围的生态环境,而且威胁到居民的身体健康,特别是不少堆存的生活垃圾受到重金属元素不同程度的污染,任意放置可能会产生严重的后果,所以评价生活垃圾的重金属元素污染程度有助于垃圾堆放场的环境影响评价以及污染防治措施的提出。
