验证理论

By using two different three-dimensional source distri- bution techniques, three-dimensional translating-pulsating source (3DT) and three-dimensional pulsating source (3DP), numerical investigations have been carried out for a high speed monohull ship (RD-200) advancing in oblique waves. The numerical results are compared with experimental values obtained from wave load tests carried out at the SSPA. These extensive test results cover different wave directions at a wide range of wave frequencies.

本文在高频运动的假设之下，使用一种简化的三维振荡(3D pulsating)格林函数，3DP，以及与实际波系接近的三维前进－振荡(3D Translating-pulsating)格林函数，3DT，对於一艘高速单体船(RD-200)进行斜浪中规则波之波浪动态压力负荷分析；理论计算将以两种三维源点法进行波浪负荷评估并与由船模试验加以验证，船模实验於瑞典SSPA方型风浪水槽进行。

To resolve this problem, according to the robotic theory, the paper suggests to get the moonquake waves in the horizontal plane coordinate in which the reference direction is the north pole of the moon by coordinate rotation transforming from the moonquake wave measured in the oblique coordinate.

在无人登月探测中，为免使月震计的投放装置过于复杂，也为减小月震计系统的重量、体积和功耗，以及增加系统工作的稳定性和可靠性，不给月震计增加机械的水平和定向调节装置，本文根据机器人理论，通过旋转变换，论证了可以从倾斜、非定向安装的月震计观测到的月震波得到以月球北极为参考方向的水平坐标系的观测，并从实验上作了部分验证，从而为这一难题的解决找到一条可行的探索途径。

This article has studied HG70 steel and HS-70 welding wires weldings,the welded joint,welding quality,and the welding operational performance,in restricts under the welding condition,Uses HS-70 welding wires,Experiments the steel plate the weld joint stretch,degree of hardness and the resilience test result indicated that,HG70 steel and HS-70 welding wires weld joints have the low crack sensitivity,The welding quality is good,Its weld joint has the fine mechanics performance,thus explained they had the fine welding match.

0前言非调质钢具有优良的使用性能和较低的生产成本，受到普遍重视。HG70钢是武钢开发的工程结构用钢，具有强度高、低温韧性好的特点。传统高强度钢一般碳当量较高，焊接性能较差。通过加入微量合金元素、采取新的控轧和调质工艺，使得HG70钢在提高强度的同时，亦保持了较高的韧性和较低的碳当量，因而从理论上讲HG70应具有较好的焊接性能，但HG70钢与HS-70焊丝的匹配情况，还有待于分析验证。

His research team tested the theory by tracking 16 people over a weekend, asking them to go to bed a little later than they would on a weeknight but sleeping-in an extra two hours.

他的研究小组跟踪了16个人在一个周末的表现来验证他的理论，让他们在周末比平时晚点上床并第二天多睡二个小时。
