超导材料

"In September 2008 around 99.9 percent purity cerium oxide is 18 yuan / kg, while the highest sold over the past 30 yuan / kg," said董森"high-tech electronics, laser, communications, superconducting materials, such as the need for Rare Earth, but China's rare-earth prices has not gone up, not their own pricing, it is a disadvantage."

"在2008年9月前后，纯度为99.9％的氧化铈为18元/公斤，而过去最高卖到30元/公斤，"董森华说，"高科技电子、激光、通讯、超导等材料都需要稀土，但中国的稀土价格并没有水涨船高，无法自己定价，很吃亏。"

The HTS rf SQUID system developed by us demonstrated a good performance inthe application of MCG, magnets telluric soundings and NDE.

我们所研制的高温超导rf SQUID系统在心磁测量、大地电磁测量和材料的无损检测应用中，显示出很好的性能。

Materials and Methods: Six patients with left frontal lobe tumors (4 gliomas, 1 germinoma, 1 intra-axial cavernoma) close to Brocca and Wernicke language areas were studied. BOLD and DTI were performed on a 3.0T magnet GE Signa Excite~(? HD_X, BOLD using the word association paradigm developed in Part I and DTT technique developed in PartII. Language activation maps and fiber tracts were superimposed upon high resolution T1 weighted anatomic images of the brain for displaying the relationship between tumor, language functional areas and white matter tracts.

材料和方法：使用GE 3.0 T Singa Excite~ HD_x超导磁共振成像系统，对6例左侧语言相关脑区肿瘤(Ⅲ-Ⅳ级胶质瘤1例，Ⅱ级胶质瘤3例，生殖细胞瘤1例，海绵状血管瘤1例)行BOLD-fMRI及扩散张量成像扫描，BOLD应用语义相关判断作为任务刺激，所有数据进行离线后处理，应用AFNI软件处理BOLD图像，观察语言功能皮层的激活；DTT采用日本东京大学的Volume-one1.56和diffusion TENSOR Visualizer 1.5进行纤维束成像处理。

The study shows the effect of the students' experience after attending the competition on technological recognition. The students changed their recognition as followed: technology is not only artificial but also professional technique including the developing progress of artificial; technology creativity includes not only fabricative technology but also the learning of knowledge, the research of the materials and the choice and discussion of producing method; in the process of technology creativity, group discussion can brings different ideas and support emotion. The attending experience makes the researchers aware the continuity in technology education.

研究结果发现研究对象参加高中生高温超导磁浮创意竞赛之经验对研究对象之科技认知有所影响，在竞赛活动后其科技认知的改变情形包括：科技不只是人工产物，也是专业的技术，也包含了人工产物的发展过程；科技创新活动并非只是实作活动，也包含科技知识的学习、材料搜寻、设计和制作方法的选择与讨论；科技创新过程中，小组合作方式可产生不同的意见来源，以及彼此支持的力量；参赛经验让研究对象认为科技的延续必须要有市场也对科技的认知更加清楚。

The results of Knight shift and spin-lattice relaxation time (T1) provide us that there are no correlation between the density of states at Fermi level and the superconductive transition temperature of the studied material.

藉由奈特位移及自旋晶格松弛时间的量测结果，我们得知对於我们所研究材料的超导转变温度和费米面上的态密度无关。

These materials could conduct electricity without resistance well above the temperature of liquid nitrogen (77 kelvins, or –196 degrees Celsius).

该材料在液氮温度（77K，-196℃）下出现了超导现象。
