Because the carbonyl in its structure is with strongly absorb-electron effect, so it is a kind of non-proton polarity solvent with high boiling point, high flash point and low melting point, use conveniently for many processing operation such as filtration, distillation, solvent extraction, and so on; it is with very low toxicity, so the harm to human body is inappreciable, and reduce the environment pollution; due to its very strong dissolvability, it can dissolve organic matter, inorganic matter, resin, polymer, etc., and activate all kinds of reagent, mix to dissolve the other high boiling point solvents; it is with very good stability, it is stable under the hot strong alkali and acidity condition, it is with water-resistance and light, oxygen stability.

246℃ m.p：—20℃闪点121℃ flash point： 121℃分子式：C6H12N2O molecular formula： C6H12N2O 分子量128.18 molecular weight： 128.18 二、DMPU的化学性质 Chemical character of DMPU 其结构中由于羰基具有强烈的吸电子效应，因而它是一种非质子的极性溶剂，具有高沸点、高闪点、低熔点，在过滤、蒸馏、溶剂萃取等工艺操作中使用方便；毒性极低，对人体危害微不足道，也减少了对环境的污染；由于它具有极强的溶解性，能溶解有机物、无机物、树脂、聚合物等，并对各种试剂具有活化性质，还能与其它高沸点溶剂混溶；具有极好的稳定性，在热的强碱和酸性条件下都很稳定，还具有耐水性及对光、氧的稳定性。

Aimed at the problem of choosing the initial value when the Newton method is used to compute the controlling unstable equilibrium point, a practical and rigorous solving scheme was presented: by identifying the controlling load bus of the given fault, and using the Thevenin equivalent circuit to represent the rest of the system at the state of the post disturbance stable equilibrium point, using the steady equivalent circuit to represent the induction motor in composite load, and then using the torque characteristics of induction motor, a point near the CUEP is gained to be the initial value. The second order normal forms was used to approximate the stable manifold of CUEP, and the local approximating boundary of the region of attraction of the post disturbance stable equilibrium point was gained. Then just by simulating the state of the system at the fault clearing time, the transient voltage stability of the system could be determined.

针对采用牛顿法求取故障后系统主导不稳定平衡点(controlling unstable equilibrium point，CUEP)存在的初值选取难题，提出一种实用但不失严谨的解决方案：通过识别给定故障的主导负荷母线，对主导负荷母线以外系统由故障后稳定平衡点处的状态进行戴维南等值，对负荷中感应电动机部分采用其稳态等值电路，再由感应电动机的转矩特性求得CUEP附近的一个点作为近似的CUEP，以此为迭代初值可靠求得CUEP；采用二阶正规型来近似CUEP的稳定流形的方法求得近似的局部吸引域边界；由仿真得到故障清除时刻系统的状态并根据该状态是否位于吸引域内判断系统的暂态电压稳定性。

Point/Snap toggle Allows you to choose between Point Mode (exact point of cursor click determines point selected) or Snap Mode (point is determined by, or "snaps to," nearest endpoint of an existing item to cursor click) while drawing .

点击/捕捉切换当你正在绘图的时候，允许你在 Point Mode 点模式（精确选择鼠标指针所单击的点位置）和 Snap Mode 捕捉模式（点位置的选择被确定在距离指针单击位置最近的一个现有内容上的一个距离指针单击位置最近的端点）之间自由切换
