The containerless processing is preceived as the new process that the able to process the sample under noncontact, without requiring the difference, container from usual melting process. I think the thing that leaves expectation that the above process is able to samples it extremly easily, under the gravit, in other words, microgravity environment which become unweight environment, although I require enormous energy, to cancel the weight of the substance, in the case that I carry out an above new process on the ground especially. Therfore, as for this process the expectation is had to the presentation of the new reseach subject that the apparatus development becomes original case, of couse, as module for the international universe station alpha installation that the operation start is planned in 2003 A.D.However, the present condition is becoming the untrodden reserch range with the interior and exterior and only the exterior and only the experent enforcemeht example for high purity ma … More terials generation does not pass to be reported. Futhermore, the establishment of the base technology including such apparatus development that materials this process is having a big problem even in the stable levitation hold of the levitation sample of course. The application person did electromagnetic force the microgravity experiment that used the parabolic flight of the airplane by using various metals and alloys sample as the hold medium of the levitation sample, into this application research enforcement period. Mastering success in the stable hold of realization and, molten sample of levitation that used a low fusion point sample and suceed in the complete stable nonexistaent big result as all with the interior and exterior. Also, I mastered success to the precise temperature measuring of the undercooling coagulation process of that the application person used the semiconductor photodiode that established independently and succeed in the containerless solidification experiment of a Nd-Fe allys sample. Furthermore, the result that becomes evident to, the generation of the metastable phase that has the new structure and physical properties that are not obtained on the ground bt the large undercooling effect that is expected removal and microgravity environment of the core generation site by an application person original view point, in other words, containerless process was shown.

无容器处理被预测为在非接触下处理样本的新过程，而无需从通常的熔化过程中进行差异。我认为，人们期望上述过程能够在引力下轻松地对其进行极大的样本样本，换句话说是微重力环境，尽管我需要增强的能量，但在我的地面上尤其是在地面上执行上述新过程，但它变得不稳定。因此，与此过程一样，期望是要提出新的研究主题，即设备的发展成为原始情况，是国际宇宙车站alpha安装的模块，即计划在2003年计划进行操作开始。不通过要报告。完全，建立基础技术，包括这种材料的设备开发，即使在悬浮样本的稳定悬浮样本中也存在一个大问题。应用人员将电磁力进行了微重力实验，该实验通过使用各种金属和合金样品作为悬浮样品的保留介质，使用了飞机的抛物线飞行，进入了该应用研究执行期。掌握了稳定的实现和熔融样品的掌握成功，这些悬浮样品使用了低融合点样品，并在完全稳定的不存在的大结果中取得了成功，因为内部和外部都与内部和外部一样。同样，我掌握了成功的成功温度测量，即应用人员使用了独立建立并在ND-FE烯型样品的无容器固化实验中取得成功的半导体光电二极管。此外，结果显示了具有证据的结果，它具有在地面BT上未获得的新结构和物理特性的产生，该效果的大潜在效应显示了核心生成位点的预期去除和微重力环境，换句话说，换句话说，换句话说，换句话说，换句话说，换句话说，换句话说，换句话说，换句话说。较少的
