The leaf shape indexes of transgenic and control seedlings increase lightly when the IAA treatment concentrations are in two regions of 0~0.01mmolL^(-1) and 1.0~10.0mmolL^(-1) respectively, while LSIs decrease when IAA concentrations are between 0.01mmolL^(-1) and 1.0mmolL^(-1) this implies the depression effect on the growth in longitudinal is greater than that in transversal for both transgenic and control mesophyllous cells.

激素浓度在0~0.01mmolL^(-1)和1.0~10.0mmolL^(-1)两个区域时，转化株和非转化株的叶形指数略有增加，而在0.01~1.0mmolL^(-1)范围内，两者的叶形指数均呈下降趋势，表明IAA在此浓度范围内，叶肉细胞沿主叶脉方向的纵向生长受到的抑制强于横向生长所受到的抑制。

D2 hydantoinase (EC3151212) can change the D type racemates of the racemic D,L252 monosubstituted hydantoin to D2N2 carbamoylase, and the leftover L252 monosubstituted hydantoin due to never reacted with D2 hydantoinase, shown as figure 1, firstly racemizing, thus makes the D,L2 hydantoin completely changes to pure optical D2N2 carbamoylase, and then be changed to D2 amino acid.

Finally transforms to the risk for the opportunity method carries on the elaboration, if we want the risk transform to the opportunity, we should enhance distinguishes and resists the risk ability firstly, nextly,we must sharpen ability which makes use of favorable conditions and avoid unfavorable conditions, and we must be good at once more using and the melt contradiction, finally we must stimulate the national cohesion by the risk pressure.

最后对风险转化为机遇的方法进行阐述，认为风险要转化为机遇，首先要提高识别和抵御风险的能力，其次要提高趋利避害的能力，再次要善于利用和化解矛盾，最后要以风险压力来激发民族凝聚力。

Single-crystal X-ray diffraction analysis of 3, 3'-BTDA and 3, 4'-BTDA showed that they both have bent and noncoplanar structures.

Glioma is still one of refractory disease in the neurosurgical field; the development of new primary and adjuvant treatment is vital. Recently, the gene therapy of glioma is developed rapidly and there are many methods about the gene therapy that include: suicide gene therapy, immunologic gene therapy, drug resistangce gene therapy, angiostatin gene therapy and so on. The sucide gene therapy is the most potential approach of antitumer, these nonmammalian genes encode enzyme that convert nontoxic prodrugs into highly toxic metablites. Cells transfected with suicide genes are targeted for specific negative selection, witch can be induced by administrtion of the corresponding produg. Among the enzyme/produg combinations, two of the best characterized system are herpes simplex virus thymidine kinase /ganciclovir and Escherichia coli cytosine deaminase /5-flourocytosine (5-FC). The formor can convert the antiviral nucleoside analogs acyclovir , ganciclovir to their nucleoside monophosphate derivatives, the monophosphate forms are subsequently phosphorylated by endogenus cellular kinases to triphosphates, these molecules are potent inhibitors of DNA synthesis.

近年来脑胶质瘤的基因治疗发展迅速，应运而生的方法有自杀基因、免疫基因、多药耐药基因以及抗血管生成基因等，其中自杀基因被认为是最有前景的基因治疗方法，它又称病毒介导的酶／药物前体疗法，是利用转基因技术将哺乳动物细胞中所不含有的自杀基因转入到哺乳动物肿瘤细胞中，该基因表达的产物可将无毒的药物前体转化为毒性药物，从而选择性杀伤该肿瘤细胞，常用的自杀基因有单纯疱疹病毒-胸苷激酶基因和大肠杆菌胞嘧啶脱氨酶基因，前者催化无毒性抗病毒核苷类似物如丙氧鸟苷、无环鸟苷等成为单磷酸核苷衍生物，然后在内源性细胞激酶作用下转化为具有明显毒性的三磷酸核苷，作为DNA合成链的终止剂和DNA合成酶的抑制剂，干扰细胞DNA的合成；后者编码的胞嘧啶脱氨酶可催化5-氟胞嘧啶（5-FC）脱氨成为5-氟尿嘧啶（5-FU），然后代谢为有毒性的5-氟尿嘧啶-5′三磷酸（5-FUTP）和5-氟-2′脱氧尿嘧啶-5′磷酸（5-FdUTP），5-FUTP通过与UTP竞争性结合而抑制mRNA和tRNA的合成，5-FdUTP则作用于胸苷合成酶，导致TMP衰竭而阻止DNA的合成，最终诱导肿瘤细胞凋亡。

Quantum mechanics breaks though the mechanical determinism in classical science, transforming it into nonmechanical determinism; it changes scientific cognitive process from the theory of reductionism to the theory of wholism; it shifts the way of thinking from pursuing simplicity to exploring the complexity; it also establishes the interaction between subject and object in scientific researches.

量子力学突破了经典科学的机械决定论，使之转化为非机械决定论；使得科学认识方法由还原论转化为整体论；使得科学思维方式由追求简单性到探索复杂性；确立了科学活动中主客体互动关系。

At last, for the needs of fully building a welloff society, this chapter posed the feasability of the transfer of peasant workers to the human capital, getting the result that peasant workers is the core in the aim of fully building the welloff society.In chapter 5, we took Qingdao as an example, made an analysis of peasant workers human capital transfer benefit. In the analysis, we found that the male education benefit rate is slightly lower than female; peasant workers working in service is a little bit lower than industry and construction; peasant workers from Qingdao city is higher than that from outsided Qingdao.

最后，该章根据全面建设小康社会的需要，探讨全面建设小康社会中农民工向人力资本转化的可行性，得出农民工人力资本发展是全面建设小康社会目标的核心动力的结论；第五章主要通过实证研究，以青岛市为例，对农民工转化为人力资本进行了成本收益分析，在实证分析中我们发现，男性教育收益率略低于女性，在服务行业工作的农民工教育收益率略低于工业和建筑业农民工，来自青岛大市的农民工教育收益率高于来自青岛以外地区的农民工。
