三比二

One day, a Roman metalworker proudly presented to Emperor Tiberius（ 42 BC- AD 37） a cup made from an unknown metal, which in all likelihood was aluminium.

有一天，罗马一名金属制品工匠得意洋洋，向提比略皇帝（公元前四十二年至公元三十七年）献上一个金属杯子。

The better technology has been obtained: taking water-EG as solvent 2-imidazolidinone was prepared. The molar ratio of the methanal (36%) to the formic acid (85%) is 1:2.8, reaction temperature is 95~100℃, reaction time is 16 h, taking cuprous chloride and triethylamine as catalyst, the molar ratio of the cuprous chloride and triethylamin to 2-imidazolidinone is 1.0% while 1,3-DMI was prepared.

较佳工艺条件为：制备2-咪唑啉酮时，以水－乙二醇混合作溶剂；制备1，3-DMI时，甲醛(36%)：甲酸(85%)摩尔比为1：2.8，反应温度95~100℃，反应时间16 h，氯化亚铜和三乙胺作催化剂，用量分别是2-咪唑啉酮摩尔数的1.0%。

Pronounce to replace an English to translate to have a few advantages with the Chinese language:A, simple go easily, so easily popular;Two, the Chinese language pronounce to translate to be advantageous to the only sex which promises a business enterprise particularly more than the English;Three, the blindness may conflict with the taboo of a certain consumption community place country after translating the meaningful English phrase, resulting in bad result, but adoption to foreigner the milli- nonsense Chinese language pronounce but can avoid this kind of phenomenon availably.

用汉语拼音来取代英译有几个好处：一、简便易行，所以容易流行；二、汉语拼音比英译更有利于保证企业专名的唯一性；三、盲目译成有意义的英文词后可能会与某个消费群体所在国的禁忌发生冲突，造成不良后果，而采用对外国人来说毫无意义的汉语拼音却可以有效地避免这种现象。

And presents some commonly process and attentions in applying the FEM software ANSYS to PCM analysis.2 Analyzed the PCM performances under the affection of piezoelectric and polymer"s material characteristic by FEM, and got the rule.3 Analyzed the PCM performances which affected by stickup layer"s materials characteristic and its thickness under the application of FEM.4 Based on the construction principles of 1-3 type orthotropic piezoelectric composite materials, the finite element model is designed and its orthotropy is analyzed, at the same time, the length/broad ratio to PCM orthotropy is also analyzed.

二、应用有限元法分析了压电相材料和聚合物基体相材料特性对于压电复合材料综合性能的影响规律。三、应用有限元法分析了粘贴层的材料性质和厚度尺寸对压电复合材料在实际应用中性能的影响规律。四、根据提出的正交异性压电复合材料的构造原理，设计出1-3型正交异性压电复合材料的有限元模型并分析其正交异性，同时分析了压电相材料长宽比对其正交异性的影响。

Whenpyridine was used as reductive decomposing agent, the expecting cholest-4-en-3,6-dione-22-al was obtained. However, when Zn/HOAc was used to decomposethe ozonide, C-4,5 double bond was further reduced to give cholest-3,6-dione-22-al as main product. 2 For the side-chain construction of compound (1), the solid-liquid phase-transfer Wittig reaction was used. When (3-methyl-2-oxobutyl)-triphenylarsonium bromide was used as reagent, the reaction can be carried out inmild reaction condition and the yield is higher than that when phosphorane wasused.

但使用Zn／HOAc作为分解剂时，却得到其氢化产物胆甾-3， 6-二酮-22-醛；2在甾体支链引入过程中，采用固-液相转移Wittig反应的方法，用(3-甲基)-2-氧丁基三苯基溴化胂作为试剂，反应在非常温和的条件下便可完成，而且产率比传统采用膦烷的方法更高；3在对某些甾酮化合物的选择性还原反应研究时，发现在〓还原体系中，当加入某些金属离子后，反应有更好的区域选择性和立体选择性。

He is penny-wise and pound-foolish to drive for two hours to buy 1 kilo potatos which are 3 fen a kilo cheaper than those in the market nearby.

As big as Jeter's game-winning RBI fielder's choice was - Cabrera raced home from third as the second baseman Roberts fielded the ball - it was Giambi's earlier pinch-hit single that fueled the inning.

和基特那个致胜打点同样贡献重大的是--牛奶在金莺二垒手Roberts传球封杀时从三垒狂奔急攻本垒--靠著稍早由指定代打吉安比的一垒安打，将本局推向精采刺激。
