Microsoft’s COM is a software architecture that allows applications to be built from binary software components. COM is the underlying () that forms the foundation for higher-level software services, like those provided by OLE. COM defines a binary standard for function calling between components, a way for components to dynamically discover the interfaces implemented by other components, and a mechanism to identify components and their interfaces uniquely.
OLE is a compound () standard developed by Microsoft. OLE makes it possible to create () with one application and link or embed them in a second application. Embedded objects retain their original format and () to the application that created them. Support for OLE is built into the Windows and MacOS Operating Systems. A () compound document standard developed mainly by Apple and IBM is called OpenDoc.
Plants in Desert Only special plants can survive the terrible climate of a desert, for these are regions where the annual range of the soil temperature can be over 75℃. Furthermore, during the summer there are few clouds in the sky to protect plants from the sun’s ray. Another problem is the fact that there are frequently strong winds which drive small, sharp particles of sand into the plants, tearing and damaging them. The most difficult problem for all forms of plant life, however, is the fact that the entire annual rainfall occurs during a few days or weeks in spring. Grasses and flowers in desert survive from one year to the next by existing through the long, hot, dry season in the form of seeds. These see [单选题]电容型验电器、绝缘杆的工频耐压试验周期为()。
