Secondly, the combination in concept and problem teaching can enhance profound comprehension of Exclusive Events and Independent Events. Finally, because Distribution is basic knowledge in teaching probability, meanwhile, the calculation for Expected Value and Variance also are based on Distribution. Thus, Distribution is the most important in teaching them, it needs to give more emphasis.

其中计算机模拟手段在概率的频率定义教学中效果明显，并且直观模型在古典概型教学中的作用也相当明显；其次，通过概念教学与解题教学的结合可以帮助学生深刻理解互斥事件与独立事件；最后，随机变量的分布列作为概率基础知识，期望以及方差的计算都是以分布列为基础的，因而，强化分布列的教学是这部分内容的重中之重。

ResultsMacroscopic examination showed no excrescence,thrombus formation,arm fractures and corrosion.The devices were covered with collagen fibrosis and discrete endocardial cells,apparent inflammatory infiltration in the devices and around the devices 1 month after implantation.The implants were nearly endothelialized,while the inflammatory reaction relieved gradually,with myocardial cells ingrowth at the edges of the device 3 months after implantation.The devices were completely covered with endocardium and fibrous tissue.Moreover,endothelial cells could be found on the smooth microscrew adaptor.The inflammatory reaction diminished with a few chronic inflammatory cells existing.Neovascularization and lymphatic vessels ingrowth could be observed 6 months after implantation.

结果所有封堵装置表面均没有发现赘生物、血栓形成、支架发生断裂及被腐蚀；术后1个月，封堵装置表面被胶原纤维和散在内皮细胞所覆盖，大量炎症细胞浸润，封堵装置边缘有小灶性炎症细胞浸润；术后3个月，封堵装置表面几乎被内皮细胞所覆盖，炎症细胞较1个月时明显减少，封堵装置内见纤维化，封堵装置边缘心肌细胞浸入；术后6个月，封堵装置表面完全被心内膜和纤维组织所覆盖，伞尖表面光滑并有内皮细胞上爬，炎症反应明显消散，但仍有少量慢性炎症细胞存在，装置内有新生的血管、淋巴管长入。

Results Sheep spleen polypeptides could significantly stimulate multiplication and transformation of mice's spleen lymphocytes; increased markedly the weight of spleen and the thymus; promoted delayed hypersensitivity; increased the quantity of antibody-producing cells; increased the level of serum hemolysin; promoted the expurgation effect and the phagocytic function of monocyte/macrophage and increased the activity of natural killer.

结果 羊脾多肽能使小鼠脾、胸腺增重，明显刺激小鼠的脾淋巴细胞增值，促进小鼠迟发型变态反应作用，提高小鼠抗体生成细胞数，提高小鼠的血清溶血素水平，但促进小鼠单核－巨噬细胞碳廓清作用不明显，增强小鼠的单核－腹腔巨噬细胞吞噬能力，有效提高小鼠自然杀伤细胞活性。

Primary atrial tumor has obvious characteristic on RT-3DE: All the atrial tumor display the same size of stereoimages as the tumor themselves. There is a clear boundary between the stereoimage of the myxoma and the atrial wall and there exists a short pedicle connecting the atrial myxoma to the atrial wall or the interatrial septum. The body of the atrial myxoma moves to and fro through the atrium and the atrioventricular valve with the contraction and relaxation of the heart with a fixative pedicle. Atrial myxoma leads to relative atrioventricular valve incompetence during systolic phase and relative atrioventricular valve stenosis during diastolic phase, but doesn't result in pathological changes of atrioventricular valve which restore to normal after exsection of the atrial myxoma. Malignant atrial tumor closely and extensively contact with atrial wall without obvious boundary, pedicle and movement with the contraction and relaxation of the heart.

所有心房肿瘤RT-3DE均实时显示与肿瘤大小相同的立体形态图像；心房黏液瘤立体形态图像与心房壁界限明显，都通过一短蒂与房间隔或心房壁相连，瘤体以蒂为固定点随心脏收缩、舒张在心房与房室瓣口之间往返运动；心房黏液瘤收缩期瘤体导致房室瓣相对关闭不全，舒张期瘤体导致房室瓣相对狭窄，但瘤体不引起房室瓣器质性病变，瘤体摘除后房室瓣功能即恢复正常；恶性心房肺瘤立体形态图像与心房壁关系密切，界限不明显，接触范围广泛，无蒂，瘤体不随心脏收缩、舒张运动。

The effects of micronutrients on production of the infertility rats induced by adenine: the exterior syndrome became normal, their relative gravity of testis and epididymis increased. Compared to model group, micronutrient group had higher spermatozoal concentration and score of spermatozoal activity and lower percentage of abnormal spermatozoa. The histology of the sexual organs also had morphology changes.

结 果： 1、微营养素组与模型对照组比较，精神体征明显改善，体重显著升高；睾丸脏器系数显著增加；精子计数由11×109/L上升到16×109/L，精子活动率由38%上升到83%，精子畸形率从77%下降到33%；睾丸组织形态学观察生精上皮明显修复。
