第一次

It took Cockcroft and Walton five years to build a machine that worked. Finally, in April 1932, they had a machine that produced a steady stream of hydrogen nuclei with an energy of about half a million volts. They were carefully measuring the quality of the stream, in no hurry to begin doing nuclear experiments. On the morning of April 13, Rutherford came into their room, saw what they were doing, and lost his temper. He told them to stop wasting their time and do some science. The next day, Cockcroft was occupied with other business. Walton was alone in the laboratory, ready to do the first experiment, using his hydrogen nuclei to bombard a target made of the light metal lithium. The result was spectacular. The lithium nuclei were split in two and fell apart into pairs of helium nuclei.

用了五年时间，考克饶夫和华尔顿建造出了第一台能运行的加速器，最终，在1932年，他们制造出了能够提供稳定氢粒子流的加速器，粒子能量大约为50万伏特，他们并没有急着做核试验，而是精心测量了粒子流的性质，4月13日清晨，卢瑟福来到他们的房间，看到他们还在测量，大发雷霆，告诉他们停止浪费时间，开始科学研究，第二天，考克饶夫就被安排了其他事情，只剩华尔顿一个人在实验室里，准备做第一次实验，用他的氢粒子流轰击用轻质金属锂作的标靶，结果极为壮观，锂原子被分裂成两半形成一对氦原子，氦原子释放出的能量比氢原子注入的多达三十倍！

It was the first suicide bombing in Israel since April of 2006 when 12 people were killed in a Tel Aviv restaurant.

这是自去年四月份以来在以色列发生的第一次自杀式爆炸，那次有12个人在特拉维夫一家餐馆的爆炸中身亡。

Success at Tannenberg - conducted by Hindenburg and Ludendorff (who received most of the contemporary credit, much to Hoffmann's resentment) essentially expelled the Russians from East Prussia, with subsequent victory at the First Battle of the Masurian Lakes in September resulting in the withdrawal of Rennenkampf's Russian First Army.

坦能堡的成功——由兴登堡和鲁登道夫（他攫取此战的绝大多数荣誉以至于引起霍夫曼的愤恨）所执行——再加上随后于9月份在第一次马苏里湖会战对雷纳肯普夫的俄国第一集团军取得的胜利，从根本上将俄军从东普鲁士驱逐出去。

The 150-million-year-old creature was first discovered in 2006 on Spitsbergen, part of Norway's Svalbard archipelago, in a polar wasteland littered with fossilized sea reptiles

这是2006年在斯匹次卑尔根群岛，挪威斯瓦尔巴群岛的一部分，一处杂乱堆放着海洋爬行动物化石的处女地，第一次发现1.5亿年前的生物。

Among the first awards of the Distinguished Service Medal for service in World War I, were those to the Commanding Officers of the Allied Armies: Marshals Foch and Joffre, General Petain of France, Field Marshal Haig of Great Britain, General Diaz of Italy, General Gillain of Belgium, and General Pershing.

其中的杰出服务奖章的第一个服务奖在第一次世界大战中，是那些在盟军军队的指挥官：元帅福煦和霞飞将军法国，黑格元帅大不列颠，意大利秘书长，秘书长迪亚兹佩塔因姬莲比利时和潘兴将军。

Based on the study of the latent image distribution and Sabatier effect of iodide uniformly distributed emulsions and core-shell emulsion s, a machanism of Sabatier effect was proposed.

通过对核壳乳剂以及均质乳剂潜影分布和sabatier效应的研究，提出了产生Sabatier效应的可能机理：第一次曝光产生的表面潜影吸附了显影剂负离子以后变成空穴捕获中心而在第二次曝光时被漂白造成影像反转；卤化银颗粒上必须同时有足够的表面敏化中心和足够的内部敏化中心，两者应相匹配。

A total of 14 patients await completion of EMR (9) or first follow-up endoscopy (5). CBE-EMR therapy was completed in 32 patients by an average of 2.1 sessions median 2, s.d.

共14名患者等待完成EMR手术（9名）或第一次内镜后续治疗（5名）。32名患者平均经过2.1次CBE – EMR手术完成治疗（中位数2，标准差0.9）。

虽然我曾四次到访中国，此次是我第一次来到广东访问。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
