We systemically discuss how to uniquely decide an infinite plane homography matrix by using the structure information in scene and how to evaluate a homography matrix which convert affine reconstruction to Euclidean reconstruction by solving absolute conic images.

系统地讨论了如何利用场景中的结构信息，来唯一地确定无穷远平面的单应矩阵，进而由射影重构恢复仿射重构，以及如何通过绝对二次曲线的像求解将仿射重构变换为欧氏重构的单应矩阵。

In our research,Wistar rats and SD rats which were parathyroidectomized were used as donors and recepients respectively.The parathyroid gland of the Wistar rat were allografted into the cerebroventricle and other different sites of the brains in SD rat s tereotaxically. Using methods of testing serum Ca~(2+) concentration,histological examination,histochemical and immunocytochemical methods and electron microscopic observation,we investigated the survival of the grafting tissue,its revascularization, infiltrating of monocytes, changes of microglia and astrocytes, the relationship of the CNS with the immune system, and the mechanism of rejection were investigated.The results as following: I .Effects on PTG after allografting into cerebroventricle and cerebral parenchyma of the brain: Testing serum Ca~(2+) conc.

本研究以Wistar大鼠作为供体，切除甲状旁腺的SD大鼠作为受体，在立体定位下将同种异体的PTG移植到大脑的不同部位，设计了侧脑室-内分泌系统移植的代替途径，比较了侧脑室内移植和脑实质内移植的异同，通过测定血清Ca~(2+)的浓度、组织学检查、组织化学和免疫细胞化学以及电镜观察对移植后PTG组织的存活、血管的再生、单核细胞的浸润、CNS内胶质细胞的变化、对免疫系统的影响及免疫排斥的机制进行了研究，结果如下：一、同种异体PTG侧脑室内移植与脑实质内移植的比较：血清Ca~(2+)的检查发现，PTG侧脑室内移植后第7天，血清Ca~(2+)的浓度恢复到8mg％以上，一直持续到移植后第8-12周；移植后第12周仍有60％移植PTG的动物血清Ca~(2+)维持在正常水平。

Then a numerical method, called Stepping Impulse Method, is introduced in the thesis to solve the percussion problem on hypothesises of instantaneity and Poisson's coefficients of restitution.

为处理复杂多体系统的斜碰撞问题，我们根据Poisson给出的冲量恢复系数的定义和碰撞的瞬时假定，给出了用于解决多体系统单点碰撞冲击问题的数值求解方法：步进冲量法。

When a trap inevitably fails, instead of simply draining the system's condensate, live steam is vented or condensate is allowed to pass back into the system, both of which inhibit heat transfer needed for process temperature control.

当一个陷阱必然失败，而不是简单地排水系统的冷凝水，活蒸汽冷凝水的排出或允许进入系统恢复，这两个抑制传热过程的温度控制所需。

Thus, too cerebral infarction patients, must be the doctor's advice and timely basis of the factors for cerebral thrombosis formal system of treatment, the only way to effectively prevent the recurrence of cerebral infarction, in particular, is suffering from cerebral infarction, in the effective melting suppository within the time (6 ~ 24 hours), timely treatment, thrombolysis, recanalization, since the view that patients return to normal, often because of financial, human and other factors, eager to hospital after reperfusion, non-systematic formal and effective cause of treatment, which led to the repeated recurrence of cerebral infarction, regret.

因此，得过脑梗塞的病人，一定要遵医嘱，及时针对脑血栓形成的基础因素进行正规系统的治疗，只有这样，才能有效地防止脑梗塞的再发，特别是患脑梗塞，在有效溶栓时机内(6~24小时)，及时治疗，血栓溶解，血管再通，自认为恢复正常的病人，往往因经济、人力等因素，再通后急于出院，不进行系统正规的、有效的病因治疗，而导致脑梗塞的反复再发，后悔莫及。
