简介：【摘要】随着社会经济发展，基础设施建设成为普遍性需求，因此也为农民工提供大量岗位，但也出现了大量农民工维权案件，这是否和农名工法律意识薄弱有关，是否是农名工打工现状的普遍现象，本文对此开展了调查研究。

简介：Heshan，在西南中国的一个城市，在一个旧煤采矿区域上被造了。由于开垦的底层，煤脉石在大堆被叠了并且引起了地质的环境问题。为了便于设计管理，煤投射脉石，我们在Heshan的Dongkuang矿做了最大的煤脉石堆的调查。第一，煤脉石的谷物作文通过sieving方法被估计，然后，代表性的分级曲线通过粗糙的谷物内容的统计方法被拉，并且最后，在分级的休息角度和谷物之间的关系被积累有不同混合比例的煤脉石学习。结果显示在煤脉石堆的上面的部分有大量谷物尺寸，并且分级的代表性的谷物是分级的井并且对容易作为充满材料被压缩。而且，休息角度的起浪的关系曲线和粗糙的谷物内容证明70%的内容是变化点上升上演并且85%休息角度的降下舞台的变化点。而且，相应于煤脉石分级的代表的休息角度是约38.4???????????p

简介：作为为词法分析的一个更有效的量的方法，几何morphometrics从NeoproterozoicEdiacaranLantian生物区系包括Flabellophytonlantianensis和Flabellophytonstrigata被用于扇形的石块Flabellophyton，华南。两传统的morphometric分析(包括的分叉的角度，长度，和宽度分发)和几何morphometric分析[包括规范的区域分析的重叠，非公制的多维的可伸缩(n-MDS)，Bray-Curtis类似簇分析(簇)和类似(ANOSIM)的分析]被执行。结果显示F之间有大种间的词法差别。lantianensis和F。strigata，除了在每种以内的一些intraspecific变化。这里，我们preliminarily建议以前定义的Flabellophyton应该至少被细分进2个类：没有，一个人由黑暗横向的有条纹的结构，和其它标记。这个描述和重新分类工作仍然与联合形态学，结构，人口，和社区生态学学习的扇形的石块的大数字需要进一步小心的观察和全面分析。

简介：借助于改变的统计方法，例如规范的根均方差(RMSE)，关联分析，实验直角的功能(文件结束)分解，等等，NCEP/NCAR的改变的季节的异例的可靠性重新分析风速度和表面空气温度(坐)经常在中国在气候变化研究使用的数据被学习。结果证明气象学的变量的RMSE比在西方的中国在东方中国是更小的，即，在东方中国的NCEP/NCAR分析的可靠性在西方的中国比那好。这能由于在分析模型和在中国的气象学的车站的“dense-in-eastern-and-sparse-in-western”的布置的地形学的效果。重新分析的风速度的异例的RMSE与增加高度减少，进一步在分析的可靠性上证实地形学的可能的影响。关联分析的结果相反地RMSE分析对应于那些，即如果RMSE更大，关联在之间重新分析并且观察数据是更坏的，并且反过来也如此。它从比较异例的EOF特徵向量被发现重新分析并且观察数据如果一个气象学的变量有更小的RMSE，异例的相应文件结束特徵向量的空间模式重新分析并且观察数据是类似的，他们的时间系数显著地被相关，并且反过来也如此。因此，文件结束模式的类似和他们的时间系数的一致性能被用来客观地估计分析的可靠性。总体上，重新分析的风速度的可靠性在春天，夏天，和秋天更好，但是在冬季更坏；并且为重新分析坐，它在夏天是在冬季和最糟的最好。
