查询词典 sintered

In the study of microwave sintering of BaTiO〓 PTC ceramics, when the applied microwave power are above than a certain value, the abnormal axial shrinkage of the sintered sample will occur, by the analysis of SEM and XRD, it is found the microstructure and phase are different with conventionally sintered sample, the reason for this phenomenon is due to orientational grain growth by the action of electric field in the microwave sintering process.

Kempers' study , the more layers the mesh screen type had, its resistance against gravity was higher, but its heat resistance and flow resistance were comparatively augmented. As mentioned in the preceding paragraph, it is extremely difficult for a single micro structure based on any of the three types to possess both low flow resistance and strong capillary force. Faced with this fact, the researchers have tried to mix the three micro structures in Table 2 into as many combinations as possible so that a composite micro structure with low flow resistance and great capillary force may be fabricated. After a thorough analysis, the groove combined with sintered metal or mesh screen has been found to be a better alternative. However, the groove combined with sintered metal will raise the flow resistance of the channel, and the aluminum substrate employed in this research cannot be sintered into a micro structure. As a result, the groove combined with mesh screen is finally chosen as the composite structure to enhance its capillary force and at the same time maintain its high permeability. In this way, the heat pipe will not fail due to the working angles.

Kempers 的研究当中提到，当网格结构越多层时，其对抗重力的能力也越强，但相对的其热阻以及流阻也越高，就如同前段所述，我们很难在单一结构当中找出一流阻低且毛细力之微结构；因此本研究便以表2中之三种微结构进行组合，找出一低流阻且毛细力强之复合式结构，经分析发现，沟槽搭配烧结以及沟槽搭配网格为较佳之组合方式，但由于烧结搭沟槽构造将会提高流道之流阻，且本研究使用铝做为基材，并无法使用烧结最为其微结构，故将采用网格搭配沟槽之复合式结构提高结构的毛细力，并维持沟槽结构的高渗透性，解决因角度造成热管失效的问题。
