2)增量步(Incrementation) 增量步包含在分析步中: Type:分析类型有两种:自动、固定(与自动相比,不易收敛); 最大增量步数(Maximum number of increments):一个分析步中最多增量步,超过该值就会停止分析; 对于非线性问题可适当调大(10000) 增量步大小(Increment size):定义每个增量步的时间长度 初始增量步大小(Ini...
编辑分析步窗口,基本信息【Basic】栏,打开几何非线性【Nlgeom】-【On】 增量【Incrementation】栏,增大最大增量步数【Maximum number of increments】,减小初始值【initial】,减小最小值【Minimum】。 完成后【OK】,回退到分析步管理器窗口,关闭【Dismiss】 六、设置边界条件和载荷 模式改为载荷【Load】 打开边界条件...
Thus, it is meant to illustrate small pieces of self-contained code that runs for not too many steps. After all, an instructor can't write hundreds of lines of code, draw hundreds of data structures and pointers, or walk through hundreds of execution steps on the board! Also, code in ...

DML(Data Manioulation Language)语句:数据库操作语句。该语句用于插入、删除、更新和查询数据库的记录,是数据库操作中最常用的语句,并能检查数据的完整性。常用的语句关键字包括 insert、delete、update 和 select。 DCL(Data Control Language)语句:数据控制语句。该语句用于控制不同数据字段的许可和访问级别,定义数...
字典是从键对象到值对象的映射。 Dictionaries are mappings from key objects to value objects. 字典由键:值对组成,其中键必须是不可变的,值可以是任何值。 Dictionaries consists of Key:Value pairs, where the keys must be immutable and the values can be anything. 词典本身是可变的,因此这意味着一旦创建...
