Solid and liquid phase diagrams have been constructed for {water+triethylamine,or+N,N-dimethylformamide(DMF) or+N,N-dimethlacetamide (DMA)} Solid-hydrates form with the empirical formulae N(C2H5)3 3H2O,DMF 3H2O,DMF 2H2O,DMA 3H2O and (DMA)2 3H2O.All are congruently melting except the first which melts incongruently.The solid-hydrate formation is attributed to hydrogen bond.The results are compared with the references
Solid and liquid phase diagrams have been constructed for {water + triethylamine, or + N, N-dimethylformamide (DMF) or + N, N-dimethlacetamide (DMA)} Solid-hydrates form with the empirical formula N (C2H5) DMF 3H2O, DMF 2H2O, DMA 3H2O and (DMA) 2 3H2O. All are congruently melting except the first which melts incongruently. The solid-hydrate formation is attributed to hydrogen bond. The results are compared with the references

仝正国从小就有大学梦,学生时代的她心气高,想着要做中国的居里夫人,可是因为家庭成分问题,初中毕业后就被打发到一家电子仪器厂当工人,按部就班地工作、结婚、生子,但大学梦依然挥之不去。1977年恢复高考时,仝正国再次心动,可当时儿子才三岁,当海员的丈夫又长年在外,她再次无奈放弃。 2001年,教育改革,高考不再限制年龄。仝正国动了心思:“我要考大学!”可家里一片反对声,全票否决!老伴儿说:“这么大年
当我还在上初中的时候,我偷偷喜欢上了班里的一名女生琳。她聪颖美丽,身材高挑,性情沉着而稳重,初中三年,我一直对她很迷恋。 然而,初三快要结束时,琳却跟着父母亲迁到另外一个城市去了。临行前,我写了一张纸条,向她表白了心意,我怕我再不说,以后就没机会了。让我出乎意料的是,琳也回了一张纸条放在我的铅笔盒里,上面写着:“两情若是久长时,又岂在朝朝暮暮。”我明白了,琳也是喜欢我的,但是这一切都来得太突
