Contributing to the confusion, the protected mode enhancements in Windows 2.0 and later were called 386 enhanced mode because they required 32 bit registers in addition to protected mode, and would not run on a 286 (even though 286es support protected mode).

Windows 2.0 和之后版本中的保护模式增强称为 386 增强模式，是因为他们除了保护模式外，还需要 32 位元的暂存器，并且无法在 286 上面执行(即使 286 支援保护模式)。

Based on varying process of generator terminal parameters after excitation fault, shortages of excitation protective principle of static stability boundary and asynchronous impedance boundary are analyzed. It proposed that excitation fault research relates to large-disturbance stability. Because dynamic power-angle character of generator after excitation fault is non-sinusoidal, there are differences between dynamic power-angle character and static state power-angle character. So it isn't ideal to protective operation result based on small-disturbance stability and static stability boundary criterion. At the same time, it proposed that asynchronous boundary impedance criterion is a constant reactive power circle moving adown j Xd′. It can ensure complete loss-of-excitation generator measuring impedance enter into the circle, but can't ensure the other condition measuring impedance including impossible losing synchronism enter. So loss-of-excitation protection would be maloperation when system voltage drops short and recovers or generator rejects load.③Based on stability principle, it puts forward setting conditions and calculation method of generator loss-of-excitation protection by direct measuring power-angle.

以励磁故障后发电机端的相关参数的变化为基础，通过对以静稳定边界和异步阻抗边界作判据的两类三种现行励磁保护在原理上存在的缺陷分析，发现：励磁故障是一个大干扰稳定性问题，励磁故障后的发电机的动态功角特性与静态功角特性有很大的差异，已远非正弦曲线，因此基于小干扰稳定性原理、以静稳定边界作判据的保护必然动作不理想；异步边界阻抗判据是一个下移j Xd′的等无功阻抗圆，它可以保证完全失磁后的发电机测量阻抗能进入该阻抗圆，但不能保证完全失磁之外的其它状态不会进入该阻抗圆，因此在系统电压短时下降或发电机突然甩负荷等情况下可能启动该保护使之误动。

In setting up the system of authorship protection of folk literary and artistic works, the protection range should not be too broad like "Bangui Agreement", not too narrow owing to their languages.

我国对民间文学艺术作品著作权保护进行制度设计时，划定的保护范围，既不能像《班吉协定》那样过于宽泛，也不应当仅限于语言形式的民间文学而使之过于狭窄；以物质形态固定并已出版的民间文学艺术作品，不应排斥于保护范围之外；未形成作品的民间素材，一旦形成整理本则应纳入保护范围。
