The biggest skin defect was 14 cm x 20 cm in size. Skin defects were repaired with flaps, myocutaneous flaps, free skin grafts and suturations. There were 4 gastronomies flaps, 6 latissimus flaps, 2 tensor fascia lata myocutaneous flaps, 1 transverse recuts abdominis myocutaneous flap, 5 plantaris medialis flaps, 3 random flaps, 12 free skin grafts and 5 suturings.

采用 7种不同类型的皮瓣、肌皮瓣、游离植皮和手术后直接缝合等方法进行修复，其中腓肠肌皮瓣 4例，背阔肌皮瓣6例，阔筋膜张肌皮瓣 2例，腹直肌皮瓣1例，足底内侧皮瓣 5例，邻近皮瓣3例，游离大块植皮1 2例，肿瘤切除后直接缝合5例。

The results of the ability of anti-oxidation scavenging DPPH free radical shows that polyhydroxy substituted N-benzoylserotonin derivatives (compound 1-10) have the generally better ability of anti-oxidation than control group, in which the IC50 of compound 1-10 ranges 8.75 to 18.02 μg/ml and the IC50 of trolox is 13.04 μg/ml. The abilities of anti-oxidation of compound 1, 4, 5, 7, and 10 are all better than the control group, trolox. Among all, compound 10 has the best ability of anti-oxidation (IC50 is 8.75 μg/ml). This study also discovers that the ability of scavenging DPPH free radical is strongly related to the number and the position of hydroxyl.

在清除DPPH自由基的抗氧化能力结果显示，相较於对照组水溶性维生素E之IC50值13.04 μg/ml，多羟基取代之N-色洛冬宁苯甲醯胺衍生物（化合物 1 ~ 10），皆具有相当不错的抗氧化能力，十种醯胺化合物的 IC50值介於8.75 ~ 18.02 μg/ml之间，化合物1、4、5、7、10的抗氧化能力效果皆优於对照组水溶性维生素E的IC50值，其中又以化合物10的效果最佳(IC50值8.75 μg/ml)，而清除DPPH自由基的能力发现与羟基的数量及其位置有关。

In the third chapter, we assume the expected returns of the risky and risk-free assets as well as the covariance matrix of the risky assets are not exactly known, but defined by some known elements, which form the vertices of this polytope. We consider three problems, the first one is when there exists no risk-free asset in the

第三章假设风险资产和无风险资产的收益以及风险资产的协方差矩阵不是完全确定的，其相关参数属于某个已知的凸多面体，分别在市场不存在和存在无风险资产的情况下定义了稳健最优投资组合问

In this paper we assume the expected returns of the risky and risk-free assets as well as the covariance matrix of the risky assets are not exactly known, but defined by some known elements, which form the vertices of this polytope. Robust optimal portfolio problems are proposed in the market with and without risk-free asset. And the analytical solutions are given out when the covariance matrix of the risky assets are exactly known.

本文假设风险资产和无风险资产的收益以及风险资产的协方差矩阵不是完全确定的，其相关参数属于某个已知的凸多面体，分别在市场不存在和存在无风险资产的情况下定义了稳健最优投资组合问题，并在协方差矩阵确定的情况下给出了问题的解析解。

At each level, the parameters, hyper parameters and model parameters are adjusted to minimize the Kullback-Leibler divergence between their posteriors and real distributions so that the variable free energy can approach the real free energy.

在指出证据框架和自由能最小化方法等贝叶斯推理方法的局限性的前提下，通过对比证据框架的方法，提出了自由能框架的概念，将通常难以求解的自由能最小化过程分解成参数自由能最小化、超参数自由能最小化、模型参数自由能最小化等层次，在每个层次上调节参数、超参数和模型参数，使其后验分布为其真实分布之同的Kullback-Leibler距最小，以使可变自由能逼近真实自由能。

The strategy that cleans out a net at that time is,: First rich other people, hind rich oneself, deal of free set up shop, make you free brake money, the money that earns when everybody only is much, ability of the net that clean out treasure makes money, it is a good zoology catenary, just like a village in, you are the richest, other is a poor, that most of predecease sure it is you, the experience that joins you to become rich with you guides everybody to become rich, what is such result?

当时淘网的战略就是，：先富他人，后富自己，免费开店做生意，让你免费闸钱，只有当大家赚的钱多了，淘宝网才能赚钱，就是一个良好的生态链，就象一个村子里，你是最富的，其他的都是穷人，那最先死的必定是你，加入你用你致富的经验引导大家都去致富，这样的结果是什么？

So we think that DML can be used to treat presbycusis by clearing free radicals. We will continue our search on free radicals.

因此我们可以推测碟脉灵也具有这一作用，可以通过清除自由基来治疗老年性聋，我们将在这一方面做进一步的研究。

In the body, SHBG binds to testosterone, which reduces the level of free testosterone. Free testosterone is capable of binding to the androgen receptors in the skin, which can induce increased sebum output. Increased sebum output leads to a fatty and oily skin which can turn into acne under the influence of the bacteria Propionibacterium acnes.

例如，雌激素增加SHBG，雄激素降低SHBG，在体内，SHBG与睾酮结合，减少游离睾酮的水平，游离睾酮在皮肤与雄激素受体结合，诱使皮脂分泌，导致油性皮肤，在细菌影响下导致痤疮。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
