碲化的

In the north limb, however, the PGE mineralization developing in contact zone is referred to Platreef. The mineralization is discontinuous, and the characteristics of different deposits vary along the trend with the changes in footwall lithology. The PGE carriers are dominantly semimetal compounds such as arsenide, telluride and antimonide.

PR接触带型矿化集中在杂岩体北段，整体上不连续，各个矿床的具体特征由于底盘岩性的多变而不同，PGE主要赋存在碲化物和砷化物等半金属化合物中，可以脱离硫化物产在硅酸盐矿物中。

Sylvanite was formed at the late mineralization stage of the Beiling gold deposit and occurs in comby network quartz, associated with native gold.

针碲银金矿产于北岭金矿的晚期矿化阶段，赋存于梳状排列网脉状的石英中，与自然金伴生。

This thesis mainly focused on the sidearm effects in catalytic Wittig-type olefination and catalytic asymmetric 1, 3-dipolar cycloaddition between nitrones and alkylidene malonates.

本文主要研究了催化的叶立德烯基化反应及催化的不对称1，3偶极加成反应中的边臂效应。在论文的第一部分，我们设计、合成了聚乙二醇负载的烷基碲化合物33(Bu-Te-PEG-Te-Bu)。

The results showed that Yb~(3+)-sensitized Tm~(3+)-doped oxyhalide tellurite glasses can be used as a kind of potential host materials for upconversion blue lasers .

结果表明Yb3+敏化Tm3+掺杂氧卤碲酸盐玻璃是一种上转换蓝光激光器的潜在基质材料。

Part Ⅱ: The evelopropanation reactions of both semi-stabilized telluronium and arsoniumylides with α,β--unsaturated ketones proceed smoothly.

第二部分：烯丙基、巴豆基、三甲基硅基烯丙基、肉桂基、苄基碲、胂两种叶立德与α，β-不饱和酮均可以成功地进行环丙烷化反应，并且表现出不同的立体选择性。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
