The results demonstrate that welds with good appearances could be obtained when welding with the appropriate processing parameters. The as-welded joint tensile strength without filler wire is 180.7 MPa, while the tensile strength is 190 MPa when welding by one side with the filler wire of AlSi12 or AlMg4.5MnZr.

研究结果表明，在合适的工艺参数下，可以获得表面光洁、正反面焊缝成型良好的对接接头；焊态下，单面焊接不填充焊丝的接头强度为180.7 MPa；单面焊接填充AlSi12，AlMg4.5MnZr焊丝的接头强度最低为190 MPa，且两种填充焊丝接头的拉伸强度无明显差异；双面焊接填充AlMg4.5MnZr焊丝的接头强度达到200.7 MPa，约为母材的90%。

Around 8pm the light was starting to fade. We were one pitch below Camp 5. Interestingly enough we heard lots of voices above us. I avoided having to lead the last pitch by getting the French party to throw down a rope that we could jumar up. Like the first night we were surprised how many folks were up and around this bivy. There was the French party. There was the Nose-in-2-days party and there was a Nose-in-hopefully-5-days party. There five of them in the last party and they had 3 or 4 huge haul sacks. There was one guy who must have been 275 pounds. He was the designated haul bag mule.

大概晚上八点，光线暗了下来，我们在第五营下一个绳距，有趣的是我们听到上面有很多声音，我不用先锋最后这个绳距，因为法国队抛下一条绳子，我们只要用犹玛上升即可，就像第一个晚上惊讶，好多人上到这个过夜处，有法国队，还有一个两天爬完Nose的队伍，还有一个希望在五天内能爬完Nose的队伍，最后这一队有五个人，三四个拖包，其中有个家伙大概有275磅重，他大概是专门拉拖包的吧。

The alkaline lavas were generated by lower degrees (0%) of partial melting and the tholeiitic lavas were generated by higher degrees (10%~30%) of partial melting.

碱性熔岩是产生于部分熔融程度较低(0%)的条件下，拉斑玄武质熔岩是产生于部分熔融程度较高(10%~30%)的条件下。

The current of the Niagara Falls rushs down cliff to come downstream and new confluent later, continue to roll in gorge buckjump, the with prep above cataract velocity of flow on the reach that in inadequacy 2 kilometers grow is horary the fall that 35.4 kilometers drop to swing and issue 15.8 meters, deduce a world to go up the maddest the the wild, most horrible, most dangerous eddy race, rush again deep the eddy pool of 38, next dragon of a flood dragon turns over, the elder brother that passes east bank Canada this, the Liweisidu of right bank United States, had rushed " devil hole race ", along final " Liweisidu affluent gorge " by enter eastwards on the west install rude lake.

尼亚加拉瀑布的水流冲下悬崖至下游重新汇合之后，在峡谷里继续翻滚腾跃，在不足2公里长的河段上以高于大瀑布的流速每小时35.4公里跌荡而下15.8米的落差，演绎出世界上最狂野。最恐怖。最危险的漩涡急流，又冲进深38的漩涡潭，然后一个蛟龙翻身，经过左岸加拿大的昆斯顿。右岸美国的利维斯顿，冲过&魔鬼洞急流&，沿着最后的&利维斯顿支流峡谷&由西向东进入安大略湖。

When NiTi alloys are tensiled at 600 ℃, the dynamic recrystallization occurs. Without electric field, the stress-strain curves were characterized by periodical undee graph, while under the electric field the curves present steady state.

在600 ℃， 2.6×10-2 s-1下，不加电场进行拉伸，得到应力—应变曲线的周期性波浪曲线，而在同样条件下施加电场时，动态再结晶与应变硬化同时发生，形成稳态的流动曲线。

In fact, we had obtained polythiophene films with high quality in BF3 ethyl ether, a kind of solvated Lewis acid. The electric conductivity of the polythiophene film is a bout 100 Scm-1. and the tensile strength is as high as 140 MPa, which is forty percent higher than that of aluminum.

事实上，我们已经从一种Lewis酸催化下的低电位聚合体系—噻吩/三氟化硼乙醚溶液中得到了高质量的聚噻吩薄膜，在降低了的聚合电位下得到的聚合物具有优异的力学及电学性能：拉伸强度达140MPa(比金属铝高40%)，电导率则可达100Scm-1。

All day and evening long on the Strip, one sees actual wedding parties, waiting under the harsh lights at a crosswalk, standing uneasily in the parking lot of the Frontier while the photographer hired by The Little Church of the West ("Wedding Place of the Stars") certifies the occasion, takes the picture: the bride in a veil and white satin pumps, the bridegroom usually in a white dinner jacket, and even an attendant or two, a sister or a best friend in hot-pink peau de soie , a flirtation veil, a carnation nosegay.

在拉斯维加斯大道，从白天到黑夜，当你在人行横道处刺眼的灯光下等待的时候，当你在弗兰提尔酒店的停车场烦躁不安地站着的时候，你都可以看到正在进行的婚礼派对。而这时由&西部小教堂&雇佣的摄影师会为婚礼现场做见证，拍下这样的画面：新娘戴着面纱，穿着无带浅口的白缎婚礼鞋；新郎通常会穿着白色晚礼服；在一旁还会有一两个人陪伴，是新娘的姐姐或是最要好的朋友，穿着粉红暖色的双面横棱缎，戴着一块富有调情意味的面纱，再插上一束康乃馨。

Based on the phase-space generating functional for a system with a singular higher-order Lagrangian,the quantal canonical Noether identities under the local and non-local transformation in phase space for such system have been derived.

基于高阶微商奇异拉氏量系统的相空间生成泛函，导出了定域和非定域变换下的量子正则Noether恒等式；对高阶微商规范不变系统，导出了位形空间中定域和非定域变换下的量子Noether恒等式。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
