Results: l、The optimal scan parameters for chinese people are flow rate of 3. 0 mL/sec and total injection 125ml. 2、Visibility of coronary arteries and segments: only those proximal and mid segment is image quality sufficient to allow a semiquantitative assessment. 3、Detection of Atherosclerotic Plaque: CT coronary imaging revealed highest sensitivities for the detection of atherosclerotic wall changes the sensitivity of stenoses was 86. 3％. 4、MSCT coronary angiography is easy to prove the entire anatomic structure of coronary and it is an effective technique for evaluating coronary patency. 5、MSCT coronary angiography correctly identified all normal controls and all patients with coronary artery fistula. The anatomic course of the coronary artery fistula was correctly classified. 6、A11 severe lesion could be visualised by

结果：1、不同的扫描技术参数所获得的造影图像质量不同，注射速率3.0ml/s组以及125m1对比剂总量组比较适合国内患者。2、多层螺旋CT冠状动脉造影可显示冠状动脉的主要分支，尤其是冠状动脉的近、中段，显示率在90％以上。3、多层螺旋CT冠状动脉造影对狭窄病变的敏感性为87.3％，能检出冠状动脉造影不易发现的细小斑块，判断狭窄的原因及斑块的特征。4、多层螺旋CT冠状动脉造影可显示搭桥血管的形态、位置及通畅程度，显示桥血管及支架的内腔，安全便捷。5、多层螺旋CT显示冠状动脉畸形准确性高（3/3），多种成像方法可弥补冠状动脉造影显示的不足。6、仿真内窥镜可显示冠状动脉内膜和内腔，显示狭窄斑块的性质。

Some bone trabeculae showed medullary cavity formation. In the control sides, the grafts were fused with tibias at 4 weeks. Some iliac crest bones degraded gradually, but the bone trabeculae of grafts also could be seen in the medullary cavity after 60 weeks.

植入髂骨的对照侧4周时移植的髂骨与周围胫骨紧密愈合，部分位于髓腔内的髂骨逐渐降解，但直到60周时仍可在部分髓腔中见到移植的髂骨骨小梁。

Results The AVM animal model was successfully created in seven CEMPs, which was similar to human brain AVM in angio-architecture, angiographic-image, embolizing behavior and post embolization pathological findings. Thromboses were found inside the CJA vessels in 4 animals and in the rest 3 the CJA vessels were shrunk without thrombus.

结果在7只CEMPs中成功制作了AVM动物模型，该模型在血管结构、造影影像、栓塞表现和栓塞后病理改变上与人脑AVM的相似。4只动物颈动静脉吻合口血管腔内有血栓形成，其余3只吻合口血管塌陷皱缩，腔内无血栓。

For the aim of obtaining high power of red laser,a Z-shaped resonator is designed, and the cooling temperature of KTP is lowered to 7℃ to compensate the thermal effect of KTP.

为获得高功率的倍频红光设计了Z型折叠腔腔型，并将KTP的冷却温度降低到7℃的较低温度以补偿KTP的热效应，最终在抽运功率317W时获得1.8W的连续波659.5nm红光激光输出。

The method is to move the stoving from inside the pellet producing apparatus to one alone stoving furnace outside the pellet producing apparatus. Inside the stoving furnace, there are waveguide tube connected to microwave generator and conveying belt in the bottom, and the pellet is fed to inside cavity of the stoving furnace on the conveying belt, stoved by microwave quickly and discharged on the conveying belt to vertical pellet furnace for roasting.

该方法是将由人造球团矿加工设备内完成的烘干段工艺移出到设备外完成，在设备外单独设置有一烘干炉体，该烘干炉体内腔有波导管与微波发生器连接，在烘干炉体的底部有输送带，球团通过输送带送入烘干炉体内腔，利用微波发生器产生的微波对球团快速加热烘干，经烘干后的球团，通过输送带送至球团竖炉完成焙烧工艺。

Flow activities inside the half stented aneurysm model were significantly diminished, specifically the pressures and wall shear stresses in the blob were decreased. It can be concluded that half bridged endovascular stents can promote intra-aneurysmal thrombus development and attenuate aneurysm rupture risk, and it is a feasible approach to treat aortic arch aneurysm.

仿真结果表明：半桥支架模型瘤腔内的流动受到明显抑制，特别是局部突起处的压力和壁面切应力大大地减小了，因此，半桥支架可以促进瘤腔内血栓的形成，并能减小动脉瘤破裂的危险，是一种可行的支架治疗动脉瘤的方法。
