The Lincoln hills rose up around me at the extremity of a snowy plain, in which I did not remember to have stood before; and the fishermen, at an indeterminable distance over the ice, moving slowly about with their wolfish dogs, passed for sealers, or Esquimaux, or in misty weather loomed like fabulous creatures, and I did not know whether they were giants or pygmies.

在我周围，林肯的群山矗立在一个茫茫雪原的四极，我以前仿佛并未到过这个平原；在冰上看不清楚的远处，渔夫带了他们的狼犬慢慢地移动，好像是猎海狗的人或爱斯基摩人那样，或者在雾蒙蒙的天气里，如同传说中的生物隐隐约约地出现，我不知道他们究竟是人还是倸儒。

The residual gas pressure in an electron tube can be measured when the tube itself is operated as a hot cathode ionization gauge.Usually,its sensitivity K is determined by the method of gauge calibration.In this paper,author try to determine the sensitivity K by ca- lculation.The formulae for this purpose have be found out,and are used for both plate and cylindrical electrode systems.

A one-step method for the synthesis of aromatic indolizine derivatives byintramolecular 1,5-dipolar cyclization reaction of 2-(2-arylethenyl)pyridinium N-ylidesin the presence of an oxidant has been studied for the first time. In the presence ofelectron-deficient olefins, however, 2-(2-phenylethenyl)pyridinium N-ylides underwent1,3-dipolar cycloadditions and then aromatized in situ by TPCD to produce indolizinederivatives, indicating 1,3-dipolar cycloaddition proceed more readily than 1 ,5-dipolarcyclization in these conditions. Pyridinium disubstituted N-ylides, readily obtainedfrom corresponding pridinium and β-chlorovinyl ketone, underwent thermalintramolecular 1,5-dipolar cyclization to give indolizine derivatives easily.Indolizinecarbaldehyde derivatives were synthesized starting from 2-pyridinecarbaldehyde in four-steps involving 1,3-dipolar cycloaddition reaction.

本文首次研究了2-(2-芳基乙烯基)吡啶N-叶立德在氧化剂存在下的分子内1，5-偶极环化反应，采用一锅法合成了中氮茚衍生物；研究了这些N-叶立德的1，5-偶极环化和1，3-偶极环加成反应的选择性，发现当有缺电子烯烃存在时，优先进行1，3-偶极环加成反应，而不再发生分子内1，5-偶极环化反应；由β-氯乙烯酮方便地得到了烯丙基N-叶立德，他们在加热时进行分子内1，5-偶极环化反应而得到中氮茚衍生物；由2-吡啶甲醛为起始原料，通过1，3-偶极环加成反应等四步反应，得到了重要的中氮茚甲醛衍生物，这些反应都具有条件温和和操作简便的特点，是合成中氮茚衍生物的新方法。

S where 3-EtO-SalAPA is the monoanionic Schiff base derived from 3-ethoxysalicylaldehyde and N-(3-aminopropylaziridine and S is C6H5F, C6H5Cl, C6H5Br, C6H5I or o-C6H4Cl2. Their gradual nature of spin-state interconversion is evidenced by the variable-temp. magnetic susceptibility and EPR data. Only a single quadrupole-split doublet is seen in the Moessbauer spectra for all solvates in the temperature range of

本文对五种组成为[Fe(3-EtO-SalAPA)2]ClO4.S的Fe自旋变异晶态配合物进行了磁学和谱学表征，所有溶剂合物的变温磁化率和EPR数据证示它们的自旋态转变性质均属渐变型，在110-300K范围内的Mossbauer谱都只显示单一的四极分裂双峰。
