第二个方法演示了使用池态数据库连接直接访问数据库。

The second method demonstrates accessing the database directly using a pooled database connection.

youdao

必须先在服务器环境中创建和配置了数据源，企业bean才可以访问池态数据库连接。

Before an enterprise bean can access a pooled database connection, a datasource must have been created and configured in the server environment.

youdao

本工程不包括流态、前处理、车间空调等冷库以外的所有制冷连接管道及保温。

This project exclude all pipes connecting with refrigeration and thermal insulation, which are beyond, in cold storage, fluidized freezer, pre-treatment, workshop air-conditioner etc.

youdao

You need a functional form that connects the value at one state of matter, the freezing point of water to another phase change, the boiling point of water.

你需要一个函数形式来,连接物质某个态对应的温度值，如水的冰点，和另一个相变,如水的沸点。

So there's going to be a line that's going to connect the initial point to the final point, and that line mathematically is not going to be the same as this one here.

连接绝热过程,初末态的曲线的方程，和等温线的方程,也不会相同。

If it was non-reversible, I would be allowed to put an initial point and a final point, but I wouldn't be allowed to put a path between them like this, connecting them together.

如果是不可逆过程，我可以画出过程的初态点,和末态点，但是我不能再像这样,画出连接这两个点的，路径曲线来。
