We even exploit polynomial technique to transform the whole image dataset and estimate sum of square error in first measure. The result indicates that the two methods are robust and of the order of our requirements, but the latter measure outperforms the first one.

我们采用多项式技术变换整个图像的数据集并且估计在第一个测量中估计均方误差和，结果显示这两种方法是鲁棒的并且具有我们要求的象素顺序，但是后一种测量优于前一种测量。

There are two kinds of spinels in a granulite terrain of Yushujgou, South Tianshan Mountain. One occurs in the intermediate and basic granulite units and is characterized by enriched Al and poor Cr, belonging to Al_spinel. In thin sections it shows dark green color and subhedral to anhedral form, and coexists with other metamorphic minerals, suggesting a neogenic metamorphic mineral of granulite facies. The other occurs in the adjacent ultramafic rock unit, belonging to Cr_spinel. In thin sections, it is dark brown in color and is scattered among olivine, clinopyroxene and orthopyroxene as irregular grains, indicating a stable residual mineral in the process of granulite facies metamorphism.

新疆榆树沟麻粒岩地体中发育两类尖晶石：一类见于中、基性麻粒岩体中，其化学成分富 Al贫 Cr ，属铝尖晶石，镜下为深绿色，呈半自形至他形粒状，与其它变质矿物共生，表现为麻粒岩相的新生变质矿物；另一类发育在空间上与麻粒岩体紧密相邻的超镁铁质岩体中，为铬尖晶石，镜下为深褐红色，呈不规则粒状分布于橄榄石、斜方辉石和单斜辉石之间，为麻粒岩相变质过程中稳定的残余矿物。

Based on Wilcoxon rank sum test, variance ratio test and Fama-MacBeth regression method, this study finds that Chinese listed companies tend to issue new equity after information disclosure. The two regular corporate financial reports around its issuing announcement are all informative, but the one before the issuing announcement does not transfer better information to the market.

基于Wilcoxon秩和检验、方差比检验以及Fama-MacBeth回归方法的实证结果表明：我国上市公司倾向于在信息披露之后公告新股发行；我国上市公司发行公告前后两个定期报告皆具有信息含量，但发行公告之前的定期报告没有向市场传递更好的信息。

In the exploitatation and utilization of Bromus stamineus, we must take the different sowing methods and plant densities into account. They have heavy influences on the forage especially in terms of the forage growth. The salt, temperature and water are important factors that affect the seeds germination,which deciding the germination time and germination place.we designed four temperature (15℃,20℃,25℃,30℃) and NaCl density(0.3%,0.6%,0.9%,1.2%) and PEG density(0.126g/gwater,0.186 g/gwater,0.232 g/gwater,0.270 g/gwater).

引进美国无芒雀麦是农业部948项目&旱生灌草植物资源的引进及开发利用&的引进草种之一，为了合理开发和利用它，本论文对引进无芒雀麦和本地无芒雀麦的种子萌发、田间种植和栽培技术3个方面进行了对比研究，比较了两种无芒雀麦生长特性；结合方差分析，确定了引进美国无芒雀麦种子萌发指标和栽培技术指标。
