The first person who appeared upon the steep stone steps was a boy in corduroy trousers and a dark linen smock-frock, who shambled down the stairs with a good deal of unnecessary clatter of his hobnailed shoes, and who was red in the face from the exertion of blowing the bellows of the old organ.

首先出现在很陡的石级上的，是一个男孩，他穿着灯芯绒裤子和黑色亚麻布长罩衫，拖拖沓沓地走下石级时，钉着平头钉的靴子弄出了很多不必要的喀啦喀啦的声音，他刚才使劲儿吹管风琴的风箱，脸还涨得通红哩。

During preparation, mercapto ethanol isooctanoate, alkyl or ester tin chloride and organic solvent are first heated and refluxed while adding catalyst; organic layer is then obtained through separating liquid and decompression distilled; and through further steps, the compound is obtained. The synthesis process of the present invention is simple, and has conversion rate higher than 95 %, normal pressure and low reaction temperature, low power consumption and less pollution, and the prepared compound has high reaction activity and low toxicity.

制备时，将异辛酸巯基乙醇酯、烷基或酯基氯化锡和有机溶剂加热回流，同时加入催化剂，然后通过分液，保留有机层，再对有机层进行减压蒸等步骤制得所述化合物；本发明合成工艺简单，转化率大于95％，反应在常压条件下，反应温度低，从而降低了能耗，减少了污染，所制备的化合物具有反应活性高和毒性小的特点，使用安全。

Montgomery told the press that on the very first day of the Bulge, as soon as I saw that was happening I took certain steps myself to ensure that if the Germans got to the Meuse they would certainly not get over the river.

Three part of research works had been carried out in the dissertation. The first part: a kind of multidentate amine modified silica gel was synthesized through the following steps:(1) introduce the amino groups onto the surface of silica-gel by the treatment of surface silanol groups withγ-aminopropyl trimethoxy silane;(2) michael addition of excess trihydroxymethyl propyl triacrylate to amino groups on the silica gel surface;(3) amidation of the unreacted double bonds of TMPTA on the surface of TMPTA modified silica gel with diethylenetriamine;(4) the multidentate amine modified silica gel was finally obtained by the reaction of amino groups on the surface of DETA modified silica gel with double bond of butyl acrylate.
