查询词典 Waterloo Bridge

A new organic compound, trans-2--5-dimesitylborylthiophene (abbreviated as DMASBT, 5) with dimesitylboryl, dimethylamino and styryl-thiophene as electron acceptor, electron donor and conjugate bridge respectively, was synthesized. Its crystal structure determined by X-ray diffraction method indicates that the B-C bond between B atom and it bridge is obviously shorter than those of between B atom and mesityl groups. This remarkably strengthened B-C bonding can be regarded as an evidence of additional p-7t conjugation between the B atom and n bridge.

合成了以含硼基团为电子受体，以二甲胺基为电子给体，以苯乙烯基噻吩为共轭桥的新化合物2-[（4'-N，N-二甲胺基）苯乙烯基]-5-二米基硼-噻吩 trans-2-[(4'-N， N-dimethylamino) styryl]-5-dimesitylboryl-thiophene（简写为DMASBT，5）。X射线衍射方法测定其单晶结构表明，硼原子与π共轭桥之间的硼碳键相对于其它的硼碳键明显缩短，硼与π共轭桥之间存在除了σ键之外的p-π共轭作用。

In order to understand the dynamic property of extradosed cable-stayed, built up its plane continous rigid-frame model and compared with each other, concluded that the former is more complex due to the remarkable coupling effect of cable, pylons and box-girder. The dynamic property of box-girder decide the dynamic property of the bridge, whose whole structure is comparative rigid. This paper indicated that the bridge is not attribute to flexible structure, because its basic free vibration cycle is more shorter than the cable-stayed bridge.

为了更好的理解矮塔斜拉桥的动力特性，还建立了平面梁单元的连续刚构模型，并与平面梁单元的矮塔斜拉模型进行了对比分析，结果表明，矮塔斜拉模型由于索、塔、梁的高阶振型耦合显著，其振型较连续刚构复杂，灵江大桥的动力特性主要由主梁的动力特性决定，其结构整体刚度较大，基本自振周期较斜拉桥短，不属于柔性结构。

Hurdle to achieve 5 stars than any other clearance is much more difficult, the difficulty must be set in hard, because its degree of difficulty is 1.25, normal 1; snipers on the 2nd floor, not the first, after the Collect medical kits position on the left, one can be moved to intermediate armored vehicles shot and killed the gunman, the reward of 500 points, second to be killed in Bridge Mobile 6 on both sides of the enemy's commander must be fast, there is a prompt commander immediately shot and killed, you can check the map to see what his position (only one is the map does not show that he left the bridge the first floor, a platform on the right side of the second floor), a certain shot hit the head, it would There are plus points, you can seize the moment to operate beret has been the gunman in his machine behind the bridge responsible for blood and shot and killed the enemy, but also make the head, not only points, but also to save bullets, do not forget He placed mines, he also spent the last task is the elimination of the second rocket tanks.

这一关要达到5星要比其它关要困难得多，难度一定要定在 hard 上，因为其难度系数是 1.25，normal 只有 1；狙击手首先不要上2楼，拿好医药包后就在左边的阵地上，一来可以即时移动到中间射杀装甲车上的枪手，有500分的奖励，二来可以在桥两边移动射杀6名敌人的指挥员，一定要快，一提示有指挥员，马上射杀，可以查地图，看他在什么方位(只有一个是地图上没有显示，他在桥左边第一幢楼的右边二楼平台上)，一定一枪打中头部，这样还可以有加分，抓紧时间你就可以操作贝蕾帽，一直让他在机枪手的后面，负责补血和射杀过桥的敌人，也要打头部，不仅有加分，而且节约子弹，别忘了让他放置地雷，他还有最后一个任务就是用火箭筒消灭第二辆坦克。
