插入键

To move the insertion point, use the arrow keys.

要移动插入点，使用方向键。

These results were different from the observation in the reaction of Cp2LnNPr2 and PhEtCCO,indicating that ligand, steric effect, electronic effect and solvents have an important effect on the insertion of a ketene into the Ln-N bond.

与phEtCCO不同的是，phZCCO偶联插入LoN键形成的新配体不发生1，5一H迁移的异构化反应，可以直接分离得到苯环参与共扼加成反应的中间体CpZLn〔oe(e6HSCphCON'p几)CphZLn-Er(11，孔(12)，Y(13)。

Check for proper fit between key and keyway.

键和键槽之间的配制要适当，不可硬行插入，否则会损坏减速机。

Inserts the selected object as a linked object into the current document.

Ctrl+Shift+Insert 组合键将选定对象作为链接对象插入到当前文档中。

To insert a non-breaking space (to keep characters together, for example in a telephone number), press Control+Space on the keyboard.

要插入不间断空格（以将字元保持在一起，例如在一个电话号码中），按键盘上的 Ctrl +空间键。

Whenever the tab key is hit, a tab character is inserted.

只要按 TAB 键，就会插入空格。

The telegraph key plugs into the blue marked phono-plug socket on the right of the aluminum heat sink.

发报键插入蓝色标记的唱机插头插座里，在右边的铝散热片上。

The energy-rich intermediate anions, eg. [CH2＝C—OH]－ as the initial product of the insertion reaction and [CH2＝CHO]－ as the direct bonding product, are able to isomerize and decompose to various final products, such as C2H－＋H2O, CH2C＋OH－ and CH3－＋CO.

其中， 通过插入反应形成的富能中间体[CH2＝C—OH]－及键合中间体[CH2＝CHO]－都可以进一步经异构化和解离生成其它各种可能产物，如C2H－＋H2O， OH－＋CH2C和＋CO产物通道。

In the presence of catalytic rhodium acetate, ethyl 2-diazo-3-oxo-per fluoroalkanoates, reacted readily with nitriles to give a series of 5-fluoroalkyl substituted 1, 3oxazoles with high regio-selectivity through a metal carbenoid intermediate. The reactions of carbenoids with noncyclic vinyl ethers or cyclic vinyl ethers afforded dihydrofuroates in good to excellent yields. Interestingly, only vinyl C-H insertion compound was obtained concerning of the reaction of carbenoids with 2, 5dimethylfuran due to the steric hindrance of methyl group

醋酸铑分解2-重氮-3-氧代-全氟羧酸乙酯形成的金属卡宾作为1，3-偶极体，可以与一系列芳基或烷基取代的腈反应，高度区域选择性地生成一系列4-乙氧羰基-5-氟烷基取代的噁唑化合物；也可以与富电子的链状和环状的烯基醚反应，以优良的产率得到一系列氟烷基取代的二氢呋喃类化合物；而与2，5-二甲基呋喃的反应，由于甲基的位阻作用，只得到金属卡宾对呋喃3-位烯基碳氢键插入产物。

In this mechanism, a phosphine ligand in the Ru hydride complexes is replaced by protonic solvent ROH to generate the chain carrier.

三、反应机理论文提出，在固载Ru基催化剂上的scCO〓加H〓生成HCOOH的反应中，CO〓的活化在Ru配合物的作用下，以反插入Ru-H键，生成金属-羧酸配合物的形式进行。

Chrysanthemum of 10 thousand birthday is lax to edaphic requirement, with the arenaceous qualitative loam with fecund, good drainage had better.

万寿菊对土壤要求不严，以肥沃。排水良好的砂质壤土为好。

He unstepped the mast and furled the sail and tied it.
