If a programmer wishes to address the A has_many B through=> [X, Y, Z] issue, they can specify the desired through association in their model class definition, and DrySQL will honour this.
如果开发者想解决A has_many B through=> [X, Y, Z]的问题,他们可以在模型类中定义想要的间接关联,并且DrySQL也希望你这么做。
Because the classpath of cl1 is regarded as a directory, that class loader is able to find class Z in that location and is able to load it.
因为cl1的类路径被当作目录,所以这个类装入器能够找到在这个位置的类z,并能够装入它。
The classpath of cl2 is assumed to be a JAR file; that class loader cannot find class Z because there is no such file.
cl2的类路径被假定为JAR文件;这个类装入器不能发现类z,因为没有这个文件。
And remember for this class, we always define z as the internuclear or the bond axis.
记住在我们的课堂上,我们总是把z方向定义为核间轴的方向。
Specifically, it's always the z that forms the sigma orbital, and the reason is at least at a minimum for this class we always define the internuclear axis as the z axis, so this is always the z axis, so it's always going to be the 2 p z's that are coming together head-on.
特别的,z总是形成sigma轨道,这是因为至少在这个课里面,我们总是定义核间轴为z轴,所以这总是z轴,所以2pz轨道总是,朝一个方向出现。
