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。

This was a fair proposal, it must be confessed, had it been made toany one that had not had a settlement and a plantation of his ownto look after, which was in a fair way of coming to be veryconsiderable, and with a good stock upon it; but for me, that wasthus entered and established, and had nothing to do but to go on asI had begun, for three or four years more, and to have sent for theother hundred pounds from England; and who in that time, and withthat little addition, could scarce have failed of being worth threeor four thousand pounds sterling, and that increasing too - for meto think of such a voyage was the most preposterous thing that everman in such circumstances could be guilty of.

其次，我必须搞到枪枝和弹药。大舱里原来存放着两支很好的鸟枪和两支手枪，我都拿了来，又拿了几只装火药的角筒，一小包子弹和两把生锈的旧刀。我知道船上还有三桶火药，只是不知道炮手们把它们放在什么地方了。我找了半天，终于找到了。有两桶仍干燥可用，另一桶已浸水了。我就把两桶干燥的火药连同枪支一起放到木排上。这时我发现木排上装的东西已不少了，就开始动脑筋如何运上岸，因为一没帆、二没桨、三没舵，只要有点风，就会把木排打翻在海里。

然而，当节面角不是相等的时，应该使用与更大的节面角的齿轮作为司机，如果两个齿轮有同一只手。

My next Care was for some Ammunition and Arms; there were two very good Fowling-pieces in the great Cabbin, and two Pistols, these I secur'd first, with some Powder-horns, and a small Bag of Shot, and two old rusty Swords; I knew there were three Barrels of Powder in the Ship, but knew not where our Gunner had stow'd them, but with much search I found them, two of them dry and good, the third had taken Water, those two I got to my Raft, with the Arms, and now I thought my self pretty well freighted, and began to think how I should get to Shore with them, having neither Sail, Oar, or Rudder, and the least Cap full of Wind would have overset all my Navigation.

There are generally two main drawbacks in the currently reported methods of dissolving wool, one of which is the low efficiency of dissolving fibers; only the wool keratin solutions with low concentration, low viscosity, relatively low molecular weight and low conversion rate have been obtained; the other drawback is, as mentioned in many patents, the wool keratin solution needed to be concentrated, purified, and coagulated into wool keratin powder, through back-permeation, dialysis techniques, in order to facilitate the application in the subsequent processes.

目前研究报道的羊毛纤维溶解方法都普遍存在有两个主要缺陷：其一是对纤维的溶解效率低，只能获得低浓度、低粘度、较低分子量、低制成率的羊毛角蛋白质溶液；其二则是因浓度低而在多数专利中需要通过反渗透、透析方法使溶液浓缩、提纯、固化成羊毛角蛋白质粉末，以方便后续加工使用。
