The results showed that both of Michaelis-Menten equation and Dagneli equation primely simulated response of photosynthesis rate to light intensity, and their effect was consilient. But the parameters of maximum photosynthesis, initial quantum efficiency and dark respiration by Michaelis-Menten equation was very distinctly bigger than them by Dagneli equation.

结果表明，两种方程均能很好地描述大豆和玉米叶片光合速率对光强的响应特征，两种方程的模拟效果是一致的，但两种方程得到的参数存在极显著差异，用Michaelis-Menten方程模拟得到的表观初始量子效率、表观最大光合速率、表观暗呼吸速率极显著大于用Dagneli方程得到的参数。

The third part of this thesis is reactive simulating calculation In this section, some well-known auxiliaries are selected to compute in density functional theory B3LYP on Gaussian 03, from which the relationship between reaction active energies of transition states and enantiomeric excess of chiral products homoallylic alcohols isobtained based on relative reactive ratio theory. Using this relationship, calculations on the reaction of more than eight auxiliaries with four other aldehydes are carried out in AMI and MNDO, proving that N,N\'-dibenzyl tartamide has higher enantioselectivity than others in this reaction.

The paradox is irresoluble: the less one culture communicates with another, the less likely they are to be corrupted, one by the other; but on the other hand, the less likely it is, in such conditions, that the respective emissaries of these cultures will be able to seize the richness and significance of their diversity.

Methods:during the year 2003 to 2006,3298 patients with vaginal delivery received 2 kinds of skin preparations.retrospective study was conducted to investigate the effect of skin preparation methods on the healing of mediolateral episiotomy.rerults:there was no different effect on the wound healing of mediolateral episiotomy between the 2 kinds of skin preparation.conclusions:non-shaving method has no adverse effect on the sterilization of operation field in vaginal delivery.moreover it can save the time of nuring,lower the costs,ease the uncomfortable feeling .therefore,we consider the non-shaving method has advantage over the shaving one.the former is simple and effective which is an ideal way to simplify nursery procedure and spare nursery resource.

Furthermore, out of 497 fAFLP markers, 80 special bands were found to be able to distinguish the four groups from each other and may be applied for germplasm characterization and molecular assistant classification of Meretrix clam.4 Molecular classification of two species of Meretrix clam based on fAFLP and ITS sequences4.1 The results of fAFLP maker analysis of S, G and W showed that each group had their own specific loci among which there were 53 special loci in W group, much more than those of S group (14) and G group (21). Among the 53 loci, nine were all dominant loci. These unique loci could be taken as molecular markers to distinguish W from other groups. The genetic similarity indexes and distance matrix between S and G groups were 0.9585 and 0.0424 respectively, but the genetic similarity indexes and distance matrix between W group and S or G group was 0.7939 or 0.7941, and 0.2308 or 0.2305 respectively. The results revealed that significant difference existed between W and S or G groups in molecular genetic structure. The phylogenetic trees by the methods of UPGMA and NJ also indicated that S and G populations were very closely related, while W population was a relatively independent cluster, lying beyond the species which S and G belong to.4.2 The internal transcribed spacer region of the rDNA from S group, G group and W group were PCR amplified and sequenced. The results showed that the size of ITS ranged between 1266-1269bp in W group, while those in G and S groups were 1614bp and 1520bp respectively. The GC content ranged 62.32-62.62% in W group while it was 61.77% in G group. The genetic distances between three populations of W group were 0.001～0.003, but it was 0.110 or 0.147 respectively between W group and G group or S group. Phylogenetic trees by NJ method also showed that G group was very closely related to S group, while W group was a relatively independent cluster.

在457个总扩增位点中找出了53个W的特有位点，远多于S群体(14)和G(21)群体，而且在53个特有位点中有9个出现频率为100%的位点，这些位点可以作为区分其它2个群体的特征性标记；S– G群体特有的位点有112个，其中有4个位点出现频率为100%，可作为S– G群体区别于W群体的特征性标记。S群体和G群体间的遗传相似性系数为0.9585，遗传距离只有0.0424，在NJ和UPGMA法构建的亲缘关系的树状图上均首先聚在一起，说明二者的亲缘关系很近，应属于种内群体间的关系；而W与S和G的遗传相似性系数均较小(0.7939和0.7941)，相对遗传距离很大而且十分相近(0.2308和0.2305)，在亲缘关系树状图上单独分出一支，也表明W与S和G群体间的亲缘关系较远。4.2 ITS序列比较分析通过对白壳文蛤、山东文蛤和广西文蛤的ITS序列扩增电泳、PCR-RFLP分析和ITS序列分析发现，W的ITS序列长度在1266-1269 bp，而S和与G的ITS序列总长度分别为1520 bp和1614 bp；从ITS1和ITS2长度来看，W分别为739-741 bp和316-317 bp，S为895 bp和414 bp，G为987 bp和416 bp；而从ITS碱基组成来看，W的GC含量在62.32-62.62%之间，而G群体为61.77%。W的3个壳色不同群体间的遗传距离仅0.001、0.002和0.003，S与G群体间的遗传距离是0.010，说明W群体内变异很小，而S与G群体间已出现明显的遗传分化，但还均属于种内群体间的遗传变异；而W与G和S的遗传距离分别达到0.110、0.147，两个类群差异显著，已远超出种内群体间的遗传变异。

The results show that the investment policy of maximizing equity value would differ from the strategy of maximizing the firm's value, and the shareholders' incentive to underinvest/overinvest would fade up with the increase of the level of old/ new debt, and that the ratio of the new and the old debt should be a meaningful measure in identifying which of the inefficient investment behaviors will occur.
