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。

Different combinations of nickel/titanium foils were used; brazing was done in vacuum at 6 x 10-6 torr at 960°C, 1010, and 1030°C for different brazing times.

不同组合的镍/钛箔使用；钎焊是在真空中在6× 10-6托在960 ℃， 1010年和1030年° C的不同钎次。

The Cooldown on Transmute: Titanium has been reduced to 1 day, and the materials required have been simplified.

转换：泰坦神铁的冷却时间降低到1天，需要的材料也被简化。

The results show that the optimum catalysts for the Michael addition and the nitroreduction were tetrabutylammoniumfioride and titanium trichloride, and the yields of the addition product and the reduction product were 54% and 78%, respectively.

结果表明，Michael加成反应和硝基还原反应的最佳催化剂分别是氟化四丁基铵和三氯化钛，在二者催化作用下所得加成产物和还原产物的收率分别为54%和78%。

The oligomerization of isoprene with titanium tetrachloride as catalyst and alkylaluminium chlorides as promotor was studied, and especially the effects of the reaction conditions on the synthetic activity and selectivity of dimer and trimer were investigated in detail.

研究了以四氯化钛为主催化剂，以烷基铝为助催化剂催化异戊二烯的低聚反应，详细考察了各种反应条件对催化合成二聚体及三聚体的活性和选择性的影响。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
