Butt Weld and docking and corner combinations Weld, in Weld ends located arc plate and extraction plate in igniting board then leads to the welding seam, joint halfway shall weld joints in front of 2.0 mm Department Firing arc, welding pieces after preheating rod will return to weld the origin, pool filled to the required thickness, before forward welding; Welding speed : Isokinetic welding requirements to ensure weld thickness, width uniform, which masks to look for hot metal and slag bath equidistance (2-3 mm)%; Arc welding rod length : different models and determined that the general requirements of arc length is stable, acid electrode generally 3-4 mm, 2-3 mm normally alkaline electrode%; Welding perspective : According to determine the thickness of two pieces of welding, welding angle has two aspects : First, the angle between the direction of the rod and welding of 60-75 ; The second is the angle between two electrodes and welding around, the same thickness as welding, welding and welding pieces incident angle of 45 ; When the thickness ranging from welding, welding electrode and thick and thin pieces of welding electrode side angle greater than the angle between the side pieces; Arc : admission to the end of each weld should be filled crater, in the direction opposite to the direction of the back-arc welding, arc welding unchanged inside pit in 1974, to prevent the crater bite of meat.

对接焊缝及对接和角接组合焊缝，在焊缝两端设引弧板和引出板，必须在引弧板上引出后再焊到焊缝区，中途接头则应在焊缝接头前方15～20㎜处打火引弧，将焊件预热后再将焊条退回到焊缝起始处，把熔池填满到要求的厚度后，方可向前施焊；焊接速度：要求等速焊接，保证焊缝厚度、宽度均匀一致，从面罩内看熔池中铁水与熔渣保持等距离（2～3㎜）为宜；焊接电弧长度：根据焊条型号不同而确定，一般要求电弧长度稳定不变，酸性焊条一般为3～4㎜，碱性焊条一般为2～3㎜为宜；焊接角度：根据两焊件的厚度确定，焊接角度有两个方面，一是焊条与焊接前进方向的夹角为60～75 ；二是焊条与焊接左右夹角有两种情况，当焊件厚度相等时，焊件与焊件夹角为45 ；当焊件厚度不等时，焊条与较厚焊件一侧夹角应大于焊条与薄焊件一侧夹角；收弧：每条焊缝焊到末尾，应将弧坑填满后，往焊接方向相反的方向带弧，使弧坑甩在焊道貌岸然里边，以防弧坑咬肉。

Many years have passed, still the same speed carriage turning the wheel, while the train was on the fast track forward.

许多年过去了，马车仍以同样的速度转动着轮子，而火车却在铁轨上飞速前进。

When the patron awoke, the vessel was hurrying on with every sail set, and every sail full with the breeze.

当船长醒来的时候，船上的每一片帆都已扯了起来，鼓满了风，他们差不多正以每小时十海里的速度疾驶前进。

However, this did not last for long, enemy spotted us and opened rifle and machine gun fire at us.

我们不知道怎么办，因为坦克还留在在后面，无法支援我们，但第三连的连长很快就解决了问题，他带来了一辆斯大林-2重型坦克，并向成员指明了目标-敌人的突击炮，坦克用它的主炮(122mm)发射了两发炮弹，其中一辆突击炮几乎被打成两截，而第二发炮弹一次击穿了两辆突击炮，我还从没看过如此的奇迹，现在我们前进的道路畅通了，连以更快的速度穿过树林，现在可以看见敌人的位置了，坦克赶上了我们，我们被命令坐上坦克，并继续我们的任务。

Their specially reinforced sidewalls allow the car to keep going at up to 80 km/h - for as much as 250 km with careful driving.

由于采用了侧壁加强技术，即使在爆胎的情况下，汽车仍可以80公里/小时的速度继续前进250公里。

It is capable of real-time parallel capture of the three seeders' seeding status by using the independent capture of the three base colors red, green, and blue of the colorized image. It is also capable of joining serial images by using image-matching techniques based on the signs.

种子粒距的检测是进行精密播种机性能检测的关键步骤，目前国内外的种子粒距检测主要以光电检测手段为主，通过记录两粒种子落下的时间间隔和地轮前进的速度来计算种子的间距 [5～ 7，12 ]。

The experiments results verified the effectiveness of the three degrees freedom input of parallel decoupling rowing driving mechanism and the correctness of the theory analysis about water strider robot in this paper. At last, it appeared that the water stride robot in this paper has good velocity response characteristics, motion flexibility, high rowing efficiency and convenient control.

在上述理论研究基础上，研制仿水黾机器人样机，在实验室环境下对仿水黾机器人进行水面前进、转弯、负重实验，实验结果验证了本文提出的仿水黾机器人三自由度输入并联解耦划水驱动机构的有效性和本文理论分析的正确性，该机器人具有良好的速度响应特性、运动灵活性，划水效率高、控制简单方便。

But here I am in China, in my second year of living in this amazingly progr essive civilization, and I can honestly say that I have never once regretted my decision to teach in China.

但是，现在我就在另，已经是在这个正以惊人的速度前进的文明国度里的第二年了。我可以真诚地说，对于在中国教书的决定，我从不曾后悔过。
