Devising and making the presacral haemostatic thumbtack projector had been successfully achieved. 2. Haemostasis time was 12.25±10.69 seconds in EG, and it was 26.00±11.52 seconds in CG (p=0.01); EG have better haemostatic effect than CG (p=0.03); However, the results of the amount of bleeding, the death rate related to the operation, the numbers of thumbtacks in two group didnt have any statistical significance.

结果：1、骶前止血钉发射器及骶前止血钉的制造是成功可行的。2、实验组术中止血时间为12.25±10.69秒、对照组术中止血时间26.00±11.52秒，实验组显著短于对照组(p=0.01)；实验组术中止血效果比对照组好(p=0.03)；实验组与对照组术中出血量、手术相关死亡率及术中所用止血钉数之间的实验结果比较无统计学意义。

Compared the voltage negative feedback wire-feeding speed regulation system supported by current positive feedback with the rotational speed negative feedback regulation system, the equivalent condition of the two systems is obtained. Then, a wire-feeding speed regulation circuit for the CO_2 welding machine is designed based on TL494 chip, which has the self-protective function under the condition of current overloading.

通过对电压负反馈配合电流正反馈的送丝调速系统与转速负反馈调速系统的比较，得出了这两种调速系统的等效条件，并采用电压负反馈配合电流正反馈技术，设计了一种以TL494为核心的具有过电流截止保护功能的CO_2焊机送丝调速电路。
