Objective to evaluate the clinical value of dr energy subtraction in chest acute trauma.methods collected sample data based on 122 clinic cases of diagnosed rib fracture patients in chest acute trauma,75 male,47 female,age between 12~65 years old,with an average 36 years old,using dr energy subtraction technique to exam and 45 cases were examined by ct in chest.results in all the cases,the diagnostic rate of single rib fracture,multiple rib fracture,rib fracture with hydropneumothorax,rib fracture with pulmonary contusion was 86.7%,91.3%,90.5% and 94.1%,97.1% in multiple rib fracture of energy subtraction image.conclusion dr energy subtraction technique which can show rib fracture and lung complication clearly has important diagnostic value for the patients with chest acute trauma.

收集122例临床诊断肋骨骨折的胸部急性创伤患者，男75例，女47例，年龄12~65岁，平均36岁，进行dr能量减影胸部摄影检查；其中有45例患者同时作ct检查。结果在本组病例中，标准胸片发现肋骨单发骨折、肋骨多发骨折、骨折合并液气胸、骨折合并肺挫伤的检出率分别为86.7%、91.3%、90.5%和94.1%；而能量减影仅在肋骨多发骨折中检出率为97.1%，其余检出率均为100%。结论 dr能量减影技术可清晰显示肋骨骨折和肺部并发损伤，对胸部急性创伤有重要诊断价值。

Results: Before intervention, the total scores, A (antisocial/disobey behavior) and N scores of the Ratter Parent Scale were of no difference. After intervention, the total subtraction scores (4.10±3.21), A subtraction scores (1.10±1.37) and N subtraction scores (1.32±0.91) in the intervention group improved significantly (P.05 -0.001), the recovery rate by clinical evaluation was 34%.

结果：干预后，比较两组Rutter儿童行为父母问卷的减分值，干预组总分减分(4.10±3.21)、A分减分(1.10±1.37)和N分减分(l.32±0.91)与对照组总分减分(l29±3.15)、A分减分(0.53±117)和N分减分(071±110)相比差异有统计学意义（均为P.05），干预组有34%的儿童恢复正常。

The arithmetic of the subtraction is based on the serial arithmetic. It can entirely enumerate every pair of subtrahend on a bit, and it also calculates two possible loaning carry values on each bit. So the subtraction can be operated through automatic selection, and complete collateral subtraction and carry operation. The method of single division is same to it. With the stenography of shifengshou we can solve the complex division. We put the formula and the technique into the DNA model to get the result. The methods all make the step decrease and change the conventional arithmetic.

减法的DNA 算法理论主要是来源于串行思路中的算法，它是将每一位上的两个减数对的所有可能进行全列举，同时考虑每一位上的两种借位信息，使得运算进行自动选择，一步即可得到最终结果的算法；除法中一位数除多位数的算法还是从我们平时所进行的串行运算中得到启发而设计的算法；而除法的多位计算思路则来源于史丰收速算法，将算法中的口诀及技巧应用到DNA 链当中，使得传统中的代数运算能够并行的得到最终的结果，这三种算法的设计都使得计算步骤减少，从根本上改变了算法的运算机制。

subtraction：减法

什么是"减法"(subtraction)呢?我是指,一方面在历史过程里面,被理智和道德逐渐减省的风俗啦、观念啦、知识啦等等,一方面在历史书写里面,渐渐消失在历史记载里面,不再被记录的风俗、知识、思想和观念,它们被历史和历史学家减去了.
