二垒

And they are guarding the Grecian and Mediterranean Sea's true storehouse—the golden mask of Agamemnon.

千百年来，重逾二十吨的三角形门楣上刻着的一对雄师护柱的浮雕和巨石垒成的高大城墙庄严守卫着宫殿，同时也守护着希腊的，也是地中海的真正的宝藏——阿伽门农黄金面具。

Combining the performance evaluation (activity, selectivity and stability) and the characterization of the catalysts (XRD, TPD, FTIR and the pore structure measure), it can be concluded that :(1)The activity of modified β is higher than MCM-22, but the selectivity of ethylbenzene is lower about 3% than that of MCM-22;(2)The mounts of diethylbenzene and the other by-products are higher 1.7 times and 1.5 times than these of MCM-22 respectively;(3)The catalytic performance of zeolite mixture is nearly equal to modified β, but the selectivity of ethylbenzene is higher about 0.5% than that of modified β;(4)The catalytic activity of zeolite is mainly correlated with the number of acid sites, strength and distribution, and the distribution of products is determined by the binding energy of ethylbenzene and the pore structure, while the stability of catalyst is affected by the amount of poly-ring aromatic alkylate and the pore structure.

以性能评价和特性表征（XRD、TPD、FTIR和孔结构测定）相结合的方式，对上述三种催化剂性能比较的结果表明：（1）改性的活性明显高于MCM-22，但乙苯选择性却低于MCM-22绝对差约3%；（2）改性(上二乙苯和其他副产物的生成量分别约为MCM-22上对应值的1.7和1.5倍左右；（3）混合型催化剂的性能与改性相仿，但乙苯选择性提高0.5%左右；（4）对乙苯合成，沸石催化剂的活性主要取决于其B酸中心数、酸强度及酸分布，产物分布则取决于催化剂表面的乙苯脱附能垒值和孔道结构，而稠环芳烃的生成量和催化剂孔道结构是影响催化剂稳定性的主要因素。

In this paper, by developing a transfer method, we study theoretically transport properties of 2DEGs through antiparallel magnetic-electric barrier structures.

本文中，我们发展了转移矩阵方法研究反平行磁电垒结构中二维电子气体的弹道输运特性，得到了弹道隧穿及共振分裂的一般性规律。

They have scored 56 runs in their last four games and, until the eighth inning on Tuesday, had put at least one runner on base for 24 consecutive innings.

他们再过去四场比赛中得的五十六分，直到星期二比赛的第八局，他们在连续二十四局中都至少有一名跑者上垒。

The calculated reaction energy barriers of ethene chemical adsorption and dimerization reaction are 108 and 149 kJmol^(-1), respectively.

计算得到的乙烯化学吸附和二聚反应的反应能垒分别为108和149kJmol^(-1)。

Into third base roared Ken Griffey, Jr.

大叫著进入三垒的是肯格列菲二世。

He tied the record of 521 home runs and had the record of 1,839 RBI.

他并平了五百二十一支全垒打与一千八百三十九打点的纪录。

If Jason Giambi can play first base and Johnny Damon is the left fielder, Hideki Matsui appears to be the favorite for DH duty.

如果吉昂比可以胜任一垒手而戴蒙担任左外野手的话，松井秀喜显然就是DH的不二人选。

Then, with runners on second and third with one out, Cano lifted a sacrifice fly to left for a 3-1 lead.

二局下技安两分打点全垒打，比数在麻吉的牺牲打之后变成3比1。

The PESes were discussed in detail. The results showed that the ground-state doublet state has lower energy barrier and is exoergic. Therefore, the reaction on the doublet PES is favorable.

结果表明在二重态势能面上的反应具有比较低的能垒，是一个放热反应，所以该反应更易于在二重态上进行。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.

在对危险的南部地区访问时，他斥责什叶派民兵领导人对中央集权的挑衅行为。

In fact,I've got him on the satellite mobile right now.
