TreeView详细用法
TreeView详细⽤法Treeview⽤于显⽰按照树形结构进⾏组织的数据。
Treeview控件中⼀个树形图由节点(TreeNode)和连接线组成。
TtreeNode是TTreeview的基本组成单元。
⼀个树的节点⼜包含⽂本(Text)和数据(Data)。
Text为String类，Data则为⽆定形指针(Untyped Pointer)，可以指向⼀个与节点相联系的数据结构。
每⼀个节点下⼦节点形成这⼀节点的Items属性，当前节点有⼀个唯⼀的Index(TreeNode的Index属性)，⽤于说明⼦节点在Items中的位置，每⼀个节点下的⼦节点是顺序编号的，第⼀个是0，第⼆个是1，依次类推。
⽤IndexOf⽅法获得⼦节点的顺序，绝对顺序(AbsoluteIndex)则是指从Treeview第⼀个项开始的顺序值，第⼀个是0，如此推下去。
Item属性则根据Index的值返回当前节点的第Index个⼦节点。
Count则表明属于此项的所有⼦节点的数量。
⽤MoveTo⽅法将Item由⼀个位置移到另⼀个位置。
Expanded属性表明是否所有的⼦项都全部展开(包括⼦项的⼦项)，为True表⽰全部展开。
IsVisible属性表明⼀个项是否在树中能被看到，如果树全部展开那么这个Item是肯定可以被看到。
HasChildren属性表明⼀个项是否有⼦项。
GetFirstChild, GetLastChild, GetPrevChild,and GetNextChild分别返回当前项⼦项的第⼀个、最后⼀个和前⼀个、后⼀个项。
GetNextSibling and GetPrevSibling则返回在同⼀Level下的下⼀个和上⼀个项。
GetNextVisible and GetPrevVisible则返回能看得到的下⼀个和上⼀个项。
如果⼀个节点有Parent，则HasAsParent⽅法返回True. Parent为当前项的⽗项。
delphi中Treeview的使用介绍
delphi中Treeview的使⽤介绍今天重点学习了TreeView的使⽤⽅法，基本的已经写了，现在主要想说的是如何显⽰数据库的资料，今天只是做了个较简单的例⼦，⼀个⽗节点下显⽰数据库中某个field的值。
代码如下：procedure TMainForm.TreeviewShow(Sender: TObject);varnode1,subnode1: TTreeNode;i: Integer;beginTreeview1.Selected := nil;node1 := Treeview1.Items.AddFirst(nil,'user');ADOTable1.Active := True;while not ADOTable1.Eof dofor i := 0 to ADOTable1.RecordCount - 1 dobeginTreeview1.Items.AddChildObject(node1, ADOTable1.FieldByName('USERNAME').AsString, nil);ADOTable1.Next;end;end;使⽤的是ADO中的ADOTable1来完成。
⼼得：今天下午⽐较重要的⼼得或许就是当你在某个函数中写代码的时候，它会⾃动把那些不符合它返回值的函数功能屏蔽掉。
打个⽐⽅，象Treeview1.Items.AddChildObject(node1, ADOTable1.FieldByName('USERNAME').AsString, nil);中的第⼆项，它要求的是返回String ,如果你使⽤得失ADODATASET的话，它就⾃动帮你屏蔽掉了FieldByName这个功能，因为返回的不是String，所以，在这种情况下最好是把你需要的函数在空⽩处得到在copy到⾥⾯去。
每⼀个节点下⼦节点形成这⼀节点的Items属性，当前节点有⼀个唯⼀的Index(TreeNode的Index属性)，⽤于说明⼦节点在Items中的位置，每⼀个节点下的⼦节点是顺序编号的，第⼀个是0，第⼆个是1，依次类推。
Fluent离散格式与欠松弛因子
离散格式与欠松弛因子离散格式：first order unwind、second order upwind、power law、quick、third order muscl。
first order unwind容易收敛，但精度较差。
当流动和网络对齐时，如使用四面体或六面体网格模拟层流流动，使用first order unwind是可以的。
但当流动斜穿网格线时，first order unwind将产生明显的离散误差，主要是因为数值扩散的原因。
因此，对于三角形或四面体划分的网格时，注意要使用second order upwind，特别是对于复杂的流动更是如此。
对于转动及有旋流的计算，在使用四边形及六面体网格时，具有三阶精度的quick格式可能能获得比second order upwind更好的结果，但在其它情况下使用quick结果也不定比second order upwind好。
power law一般产生与first order unwind相同精度的结果。
third order muscl格式可以应用在任何网格和复杂的3维流计算，相比second-order upwind，third-order MUSCL 可以通过减少数值耗散而提高空间精度，并且对所有的传输方程都适用。
third-order MUSCL 目前在FLUENT中没有流态限制，可以计算诸如冲击波类的非连续流场。
有时，为了加快计算速度，可先在first order unwind下计算，然后再转到second-order upwind下计算，如果second-order upwind下遇到难以收敛的情况，则可考虑使用first-order upwind。
欠松弛因子：pressure(默认值0.3)、density(1)、body force(1)、momentum(0.7) 、turbulent kinetic energy(0.8)、 turbulent dissipation rate(0.8)turbulent visconsity(1).一般情况下，我们没必要改变这些值。
