Bicycle [2,2, 1]-2,3-dicarboxy-2,5-heptadiene was synthesized (N). Photosensitized electron transfer isomerization of N to quadrocyclo[2,2,1,02.6,03.5]-2,3-dicarboxy-hepta-ne(Q) was studied. Tetraphenylporphyrin and crystal voilet were used as sensitizers. The highest optical radiation intensity (500-600nm) of solar energy coujd be storaged by the isomerization of N to Q. Q was catalyzed reversing to N by complex cobalt(Ⅱ) and tetraphenylporphyrin. The mechanism of photoisomerization was also discussed.

以四苯基卟啉和结晶紫为敏化剂,在太阳高密度能量辐照范围内(波长500—600nm)实现了双环[2,2,1]-2,3—二羧基-2,5-庚二烯(N)异构化为四环[2,2,1,0~(2.5),0~(3.5)]-2,3-二羧基庚烷(Q)。以四苯基卟啉钴为催化剂,可顺利完成Q向N的转化。讨论的N异构化为Q的机理中包括光敏化单线态电子转移过程。

The magnetic moment and the magnetostriction decrease slightly withthe increase of totel Si + B content. A maximum of the Curie temperature appears atabout 25 at.-% of Si + B. The magnetic anisotropy is uninfluential by the content ofSi + B, but much influence by the demagnetization effect of streak. A qualitativeexplanation of the experimental phenomenon seems to be noted by aid of the elec-tron transition and structure model of amorphous alloy.

非晶态Fe_(1-x)(Si,B)_x合金的磁矩和磁致伸缩随着Si和B含量的增多而缓慢降低,而Curie温度约在25%(Si+B)含量时呈现出最大值;Si与B的含量对磁各向异性并无明显影响,但表面条纹退磁效应对磁各向异性却有较大的影响。这些实验现象可以借助电子转移和非晶态合金的结构模型得到定性的解释。

It was found that for the amorphous alloy (Fc80 Ni20)78Si22-xBx the magnetic anisotropy and magnetostriction will gradually decrease with the increase in B content and the decrease in Si content but , on the contrary , the Curie temperature and magnetic moment tend to increase gradually in the same time.

It was found that for the amorphous alloy (Fc80 Ni20)78Si22-xBx the magnetic anisotropy and magnetostriction will gradually decrease with the increase in B content and the decrease in Si content but , on the contrary , the Curie temperature and magnetic moment tend to increase gradually in the same time. As one of the surface conditions of amorphous alloys strap, the streak effect is of importance to induce the macro magnetic anisotropy. To explain qualitatively the phenomenon, such theories as the demagnetization effects of streak, molecular field approximation and electronic transition model, ect., are applied to.

非晶态(Fe_(80)Ni_(20))_(78)Si_(22-x)B_x合金的磁各向异性和磁致伸缩随B元素含量的增加和Si元素含量的相对减少而缓慢降低。居里温度和磁矩却呈现出缓慢增高的变化趋势。非晶态合金带的表面状态条纹效应是引起宏观磁各向异性的重要因素之一。对于上述实验现象本文应用退磁效应、分子场近似和电子转移模型等理论予以定性解释。
