mapping the world of harry potter是什么意思

下面这段代码看不懂,求大神赐教
public ActionForward save(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response)
throws Exception
{
try
{
DynaActionForm dynForm = (DynaActionForm) form;
ArtModel artModel = new ArtModel();
BeanUtils.copyProperties(artModel, form);
int artId = 0;
String pageIds = dynForm.getString("pageIds");
String[] pageId = pageIds.split(",");
int pageNum = Integer.parseInt(dynForm.getString("pageNum"));
List pageList = new ArrayList();
for (int i = 1; i i
&& null != pageId[i - 1] && !"".equals(pageId[i - 1]))
{
page.setId(Long.parseLong(pageId[i - 1]));
}
pageList.add(page);
}
artModel.setPageList(pageList);
// 文章页面数清零
dynForm.set("pageNum", "0");
// 编辑保存
if (null != artModel.getShowArtId()
&& !"".equals(artModel.getShowArtId()))
{
String magaId = artModel.getMagaId();
String colId = artModel.getColId();
String artShowId = artModel.getShowArtId();
logger.info("edit article magaId = " + magaId + " colId ="
+ colId + " artShowId = " + artShowId);
Article article = new Article();
article.setId(Integer.valueOf(artShowId));
article.setName(artModel.getShowArtName());
article.setMagazineId(Integer.valueOf(magaId));
article.setColumnId(Integer.valueOf(colId));
ArticleDao.getInstance().updateArticle(article);
Magazine magazine = MagaDao.getInstance().getMagaById(magaId);
// PageDao.getInstance().delPageByArtId(artModel.getShowArtId());
// FileOpreration.delAllFile(magazine.getMagazineURL()
// + Constant.SLASH + artId);
int id = Integer.valueOf(magaId);
String str = Constant.FILE_PATH + Constant.SLASH + id;

There is no specific mapping between A and B.请问大家,这里的mapping怎么解释?

英语翻译
1、if there is a mapping of the natural numbers onto a set u(not necessarily one-to-one),then u is either finite or countable.
2、the existential-universal implies the universal-existential but not vice versa; the universal-existential is equivalent to asserting the existence of a function from the domain of the universally quantified variable to the domain of the existentially quantified variable.

Mapping—The mechanism by which virtual addresses are translated into
physical ones (very similar to cache mapping)

Analyze的时候报出的错误,最好能教教我怎么修改~
The mapping of Load/BC "fix" to FEM has found nodes close to geometry Solid 12.149 that are associated to adjacent geometry.The application automatically included 0 of these nodes,that were found within the Global Model Tolerance (currently 0.005).Use the Geometry Show-Surface-Nodes tool for verifying which nodes are associated,and adjusting the Global Model Tolerance if necessary.This check may be disabled from the Preferences/Finite Element form.

Linear Mapping
Let V be an n dimensional vector space with basis B.
Let S be the vector space of all linear operators L: V->V.
Define T: S->M(n,n) by T(L)=[L]_B.
Prove that T is linear.

各位大神,这道题怎么做?中文英文都可以.
给各思路也行.
谢谢了!

tomcat 启动后报错 报的两个错很郁闷 请教具体原因
HIBERNATE.CFG.XML配置文件中 导入的实体类的映射文件确定是正确的 因为该项目在其他机子上部署是没问题的
实体类配置文件中的类和属性这些映射也都正确
Admin 实体也未重复定义 这些问题我在提问之前都检查过了的
不过现在问题已经解决了 我换了个版本的tomcat 重新部署 具体原因还是没找见！

Although genetic linkage and association mapping are based on the same underlying phenomenon — namely,
recombination — in practice these approaches have different characteristics for localizing trait loci,each with particular
advantages and disadvantages.
In linkage analysis,recombination events are directly observed (or inferred) in a family pedigree within a limited number
of generations,whereas in association analysis we make use of the consequences of non-recombination over many past
generations within a short interval surrounding a disease locus.Importantly,the difference between the two approaches
often leads to the identification of different classes of disease-related genetic variants.These differences could provide at
least a partial explanation for the often poor correspondence between the susceptibility loci identified in genetic linkage
and genome-wide association studies.
The table compares linkage analysis,represented here by an affected sibling pair (sib-pair) with one parent
heterozygous at a specific marker,and genetic association analysis,represented by a trio family with one affected
offspring and a heterozygous parent.In affected sib-pairs,what is estimated is the proportion of pairs sharing an allele
that is identical by descent; that is,as copies of one parental allele,where the identity of the shared allele is irrelevant.
The sharing proportion is a simple inverse function of the recombination fraction:high sharing proportion corresponds
to a small recombination fraction,which in turn points to genetic linkage.In trio families,the estimated quantity is the
proportion of affected offspring inheriting a specific marker allele:an excess of over 50% is indicative of association.
