According to the H NMRstudy, it was found that the protons on the cyclopentadienyl ring of 〓 were not splitted, but when one proton on the cyclopentadienylring was substituted by methyl, that is in〓 complexes, thefour protons on the ring were splitted into four groups,the 〓 between the onesignal and the others is large, the total splitting is over 2ppm. The splittings werealso affected by the halides linked with the titanium, they increase according to theorder of CI, Br, I. By the study of the 〓 Sn NMR, it is found that the chemicalshifts of 〓 are present in low field. It is assume that the large space strain causesthe angles of the tin linked with ligands deviate from the normal tetrahedral anglesresults low field shift for 〓Sn. And by MS study,there were no molecular ions for 〓 complexes in the spectra. However, for 〓 when X=CI,Br,NCO and Ar is tolyl or phenyl group,there were molecular ions,but theirabundances were very small,and no that for the iodide was found.

钛上的卤素对茂环氢的裂分也有影响，依〓，Br，I顺序，卤素对茂环氢的裂分依次加大；通过对〓的研究发现，以上这些化合物〓的化学位移都出现在低场，认为大的空间张力造成的锡的键角偏离正常的锡的四面体键角是造成〓化学位移出现在低场的原因；对这些化合物质谱的研究发现，〓系列化合物得不到分子离子峰，而〓系列的化合物，当X=〓，NCO和苯环上不带取代基或只带甲基时，则出现分子离子峰，但丰度很低，而相应的碘化物和其它化合物则没出现分子离子峰。

A process for manufacturing seamless flux-cored welding wires 0.8 to 4 mm in diameter with excellent cracking resistance and primer proof quality and containing very little diffusible hydrogen suited for the welding of high-tensile steels and steel structures subjected to large restraining forces by dehydrogenating by high-temperature heating comprises the steps of heating a straight wire 8-15 mm in diameter by direct electric heating through a first and a second pair of roll electrodes spaced 2 to 5 m apart and a ring transformer disposed therebetween to a temperature between 620 and 1100 degrees Centigrade, cooling the heated wire to a temperature not higher than 500 degrees Centigrade with a coefficient of heat transfer not higher than 250 kcal/m2 h degree Centigrade, and drawing to the desired diameter.

一种用来制造直径0.8至4mm的、具有优异的抗裂缝力和底层涂料防护质量并含有非常少的扩散氢的、适合于焊接高强度钢和承受大约束力的钢结构的无缝药芯焊丝，通过用高温加热进行脱氢处理来制造的工艺包括步骤：通过经布置成相隔2至5m的第一和第二对辊电极并经布置在它们之间的环心变压器的直接电加热，把直径8至15mm的直焊丝加热到620与1100℃之间的温度；用不高于250kcal／m2h℃的传热系数把已加热焊丝冷却到不高于500℃；以及拉伸到想要的直径。
