For a fixed L, we
40、 compare all values of Ctotal and choose the lowest one. The results of this method are presented in Table6.例 3 According to the above data, we can see that many of the European countries have the high rates of the donor, particularly inSpain. This phenomenon shows that the organ transplant is also
41、hot inEurope. Although the relevant policies and statutes in these countries are less comprehensive than that in U.S, there still a lot what U.S could learn from. Here, we mainly analyze the organ transplant policies inSpain, U.K andKoreathis three countries.The population contained in each region i
42、s summarized in table 1.（在表后对数据的内容进行总结）例 4图表的解释部分As indicated in Table 6, there is fairly good agreement between the recommended number of booths for a typical day and for peak hours. However, we note that the optimal booth number for a typical day never exceeds that for rush hour. Rush hour seems t
43、o require slightly more booths than a typical day in order for the plaza to operate most efficiently.Each value in Table 6 is representative of approximately 20 trials. Through these trials, we noted a remarkable stability in our model. Despite the stochastic nature of our algorithm, each number of
44、lanes was almost always optimized to the same number of tollbooths. There were a handful of exceptions; they occurred exclusively for small numbers of highway lanes ( 3 lanes). Integer values are presented in Table 6 only because fractional tollbooths have no physical meaning.3、表前表后有引入引出 ，且中间对两表之间进行
45、比较例 1表的解释部分We can obtain the data which is involved with the status of the American OrganTransplant from the data banks. We have collected the demand of the various organs in United States to date, the annual donors，transplants and the demand (Here taking the kidney for example, by years 1995-2006)F
46、rom the above table1, we can see that the kidney accounts for 73% in thetotal of the organ transplants. It accounts for a very large proportion as a most important organ which can be transplanted. Therefore, we only need to discuss the status of the kidney transplant here, being able to achieve the
47、analysis and research on the organ transplant.According to the above data, we can get the figures as follow:例 2 So after many times simulation under the conditions discussed above, we obtain statistic results as follow:表的解释部分By analyzing the above result, we can find: When there are more donors (mor
48、eresources), the number of transplant will increase obviously, and the matching rate changes only a little; When the network is divided into 11 regions (small networks), the costs of the transport and preservation of the organ will be reduced greatly.例 3Table 7 reports the general patient statistics

The first column in these tables reports the total live donor transplants as percentage of the population size, which is the sum of next two columns, transplants from own compatible donor and transplants from trades. The forth column is the percentage of patients upgraded to the top of the waitlist as heads of w-chains. The fifth and sixth columns report the quality of ma
