可改进的

Although the IPv4 has already obtained to make the person is hard to place the success of the letter, along with lately- apply flow out continuously now, the traditional IPv4 agreement is hard have already supported an Internet to extend further with the characteristic of the new business, among them the most attractive with the most remarkable of can improve it to be placed in in its address space of size, expand a sex problem,manage a problem and choose road in addition a difficulty,service of the consignation and the safety problem of the improvement and the service quality characteristic is also convex appear, so the IPv6 transitions become no time for waiting now.

虽然IPv4已经取得了令人难以置信的成功，但随着新应用的不断涌现，传统的IPv4协议已经难以支持互联网的进一步扩张和新业务的特性，其中最显眼和最值得注意的可改进之处在于其地址空间的大小，除此之外扩展性问题、管理问题、选路困难、服务的改进和服务质量特性的交付以及安全性问题也凸现出来，因此现IPv6过渡变得迫不及待了。

To pay attention to carry out effective cardiopulmonary resus-citation,hemostasis by compression and deep vein intubation rapidly in the initial stage of emergency.The carotid shunt tube plays an important role in severe carotid injury and re-establishment process.We use external jugular vein to transplant and re-establish,which are rungwith artificial blood vessels for the long distance carotid injury and achieved the best result.We expose as fully as possible for the hepatic venae and the posthepatic post caval injury,and adopt effective methods to stop bleeding and repair.The application of blood shunt pump could raise the success rate for those severe patients.The self-double vastransplantation with both ends being all trousers-style one opening solve some problems such as there are no suitable caliber self-transplantation blood vessels and the artificial blood vessels are easy to occur obliteration for long-term and so on for the great or middle blood vessels.We use improved Fogarty duct and anterograde intubation to eliminate thrombus could eliminate thrombus effectively and avoid accessory injury for the deep vein injury and extensive thrombosis.

抢救初期要注意进行有效的心肺复苏、压迫止血和快速进行深静脉插管；颈动脉转流管在严重颈动脉损伤重建过程中有重要作用；对长距离颈动脉损伤用颈外静脉移植外环包人造血管重建，可取得最佳效果；对肝静脉及肝后下腔静脉损伤，要充分暴露，采用有效方法止血和修复，对病情极危重的凶险性出血者，血液转流泵的应用可提高成功率；对大、中血管损伤，两端均为裤式单开口自体双血管移植，解决了无适宜口径自体移植血管和应用人造血管远期易闭塞等问题；对深静脉损伤并广泛血栓形成者，应用改进的Fogarty导管和顺行插管取栓法，可有效取栓并避免了副损伤。

Based on this, in the usual classroom instruction, improves the teaching method, provides the innovation to the student the environment, the multi-encourage student questioned, provides the opportunity which for the student may innovate, simultaneously strengthens the student thought training and the improvement appraisal way, lets the student by this be glad in mathematics learning process to explore happily, does everything possible to solve, and achieves as far as possible has the innovation, only then insisted like this, the innovative ideology will certainly to strike root in the hearts of the people, the innovative spirit even more carries forward, student's intelligent wisdom can transnormal effectively displays.

在此基础上，在平时的课堂教学中，多改进教学方法，给学生提供创新的环境，多鼓励学生质疑，为学生提供可创新的机会，同时加强学生思维训练和改进评价方式，以此让学生在数学学习过程中都乐意愉快地去探索，想方设法去解决，并且尽量做到有所创新，只有这样坚持下去，创新意识必将深入人心，创新精神更加发扬光大，学生的聪明智慧才能更有效地超常规发挥出来。
