Conventional imaging technique which unsubtracted bone was used first,use 3D treatment on workstation to reconstruct cerebral vessels,to diagnose aneurysm,vascular malformation and tumor as well as to evaluate the preoperative and postoperative efficacy.Subtract bone techniques including one by one slice subtraction,semi-automatic digital subtraction radiography,matched mask bone elimination and control tube exposure light spot imaging technique can show the vessels more clear without the interference of bone as well as the relationship between vessel and pathological changes more accuracy.

首先是未去骨的常规成像技术，利用工作站进行多平面重建技术、最大密度投影、容积再现、表面遮盖法等多种三维处理得到头部血管及肿瘤图像，对动脉瘤、血管畸形及肿瘤血管进行病变诊断及术前、术后评价；其次是近年出现的逐层减影、半自动数字减影、匹配蒙片骨去除法及控制球管曝光点的减影等去除颅骨的减影技术，没有颅骨的干扰血管显示更加清楚，血管与病变关系显示更准确。

Next, regarding question two, because present uses the injection contraceptive the method to maintain this population the stability, moreover already did not have the individual to move away or the situation which poaches, for this reason we transform this populations stability to ask this population every years newborn baby quantity to subtract this year death individual the quantity differential value; Moreover from this population year quantity with this year the end of the years quantity differential value, when tends 0, namely thought that this community individual quantity is stable, thus the question stability problem transforms to ask simple targets optimization problems model building; Carries on using MATLAB to the model obtains, obtains, when did not consider when uncertainty factor influence must inject the medicine female animal quantity is 276 heads, but when had considered after twin and by duplicate injection these two uncertainty factor influence, obtains must inject the medicine female animal quantity is 352 heads, including 110 are by the duplicate injection.

其次，对于问题二由于现在采用注射避孕药的方法来维持该种群的稳定，而且已经没有个体被运走或被偷猎的情况，为此我们把该种群的稳定性转化为求该种群每年的新生幼仔的数量减去该年死亡个体的数量的差值；另外从该种群年头的数量与该年年底的数量的差值，当趋于0时，即认为该群落的个体数量是稳定的，从而把问题的稳定性问题转化为求单目标的最优化问题建立模型；利用MATLAB对模型进行求得，得出当不考虑不确定性因素影响时要注射药物的雌性动物数量为276头，而当考虑了双胞胎和被重复注射这两个不确定性因素影响后，得到要注射药物的雌性动物数量为352头，其中有110头是被重复注射的。
