The author prepared bulk SmBaCuO single crystals with 5×5×5mm〓 by MTG method. The SmBaCuO crystals were proved by X-ray diffraction and X-ray back-reflection Laue technique. SmBaCuO crytal became 90K zero resistance superconductor by the study of the relation of transition temperatures and heat treatment conditions.

采用MTG法及其它类似的方法制备的YBCO超导体的小样品具有很好的超导电性能，但要使YBCO超导体获得实际应用，必须制备超导电性能优异的大块YBCO超导材料，采用籽晶诱导技术是制备高性能大块YBCO超导体的有效方法，因此，制备较大尺寸高质量的〓〓单晶是籽晶诱导技术成败的关键，作者用MTG工艺制备了尺寸达5×5×5mm〓的大块〓单晶，X-ray衍射及X-ray劳埃像法证明MTG法制备的〓晶体具有很好的单晶特性。

We firstly studied the material feature in X-ray band. Base on this, we defined the diffractive screen function. Subsequently, by using diffraction theory, it studied the focus performance and transmission efficiency of X-ray compound lens.

1理论研究。首先研究了X射线波段的材料特性，并据此得出了物面的衍射屏函数，然后利用衍射理论研究了X射线组合透镜的聚焦性能和透射效率。

Alternatively, the spectral softening above 2 GeV could be due to gamma-ray absorption via photon-photon pair production on the soft X-ray photon field of the host active galactic nucleus, but such an interpretation would require the dissipation region to be located very close (l~100 gravitational radii) to the black hole, which would be inconsistent with the X-ray spectrum of the source.

另外的关于2 GeV以上能谱变软的可能解释是高能光子和寄主活动星系核的软X射线辐射场通过电子对产生反应而被吸收，但是这个解释要求反应区域要很靠近中心黑洞(1~100倍引力半径)，这和3C 454.3的X射线测量谱相矛盾。

The dissecting of samples in group2 were difficult. The root of pulmonary artery and ascending aorta failed to be unfolded because fibrous tissue was tough, right and left fibrous trigone were too firm to be solved by hand. Cardiac muscle fibers couldn't be stripped along myofibrillar trajectory since they were prone to break because of their friability.

组2的心脏解剖困难，表现为纤维组织坚韧，游离肺动脉非常困难；徒手无法松解左、右纤维三角，肺动脉和主动脉根部的游离非常困难；心肌纤维坚硬、质脆，解剖时容易断离成碎块，无法沿纤维走行方向剥离。

We have battled against the odds in a province that has become increasingly violent.

我们对在一个争夺日益激烈省的可能性。
