最好用射线(RT)检验,价格和超声波(UT)差不多,这两种检验方法都是检验焊缝内部有无缺陷的,表面检验的话着色(PT)是比较合适的,可以检验表面气孔、裂纹,或者煤油渗透...
The university gave ten Plant Lamps to the villagers of Nuevo Saposoa on October 20. So far, they have been a huge success! Elmer Ramirez, the UT professor who invented the lamp, believes the Plant Lamp could help improve the lives of many people, especially small rainforest communities, 42% of whom have no electricity.
10月20日,我校向新萨摩萨的村民赠送了10盏植物灯。到目前为止,它们已经取得了巨大的成功!发明这盏灯的德克萨斯大学教授埃尔默·拉米雷斯认为,植物灯可以帮助改善许多人的生活,特别是小型雨林社区的人们,那里42%的人不能使用电。
The UT team put special sticks inside the soil to capture the energy and keep it in the lamp's batteries for later use.
UT 团队在土壤中放置了特殊的棍子来获取能量,并将其保存在灯的电池中以供以后使用。
Luckily, researchers at the University of Technology (UT) in Lima, Peru heard about their problem and found a wonderful solution.

This piston is being brought out, so we expect 0 the work to be negative, negative. And we start o V2 ut with zero volume. We end up with a volume p2 of V2, and the external pressure is constant to p2.
所以我们可以想象功是负的,开始的时候体积是,最终的容积是,外界的压力恒为。

In some West Bank towns Hizb ut-Tahrir, an extreme Islamist group, has been making headway.
Hizb ut-Tahrir faces a similar balancing act between its party faithful and the real world.
And with support from HEAT, Mplayer, and UT's "find the server" feature, you'll always find online opponents.
