无风险的

If an affected child is born to clinically unaffected parents, it is likely that the child has a de novo mutation, and the risk to sibs is far less than 50% but above the population risk because of reported cases of somatic and germline mosaicism.

如果临床无症状的父母但下患病儿童，很可能这个儿童发生了新生突变，而患儿的兄弟姐妹患病的风险远比50％小得多，但比普通人群风险高因为曾报道过体细胞和生殖细胞嵌合体的案例。

This article introduces the research condition of the modern Portfolio theory China under no addimission conditions and analyses the usage of short sale.

But with the change of circumstances, the uncertainness of investment projects increases and these traditional decision approaches are challenged.

在第一章中，本文讨论在风险中性世界中的投资项目决策实物期权的价值评估问题，并假设投资项目的未来收益变化率S t服从如下的几何布朗运动：其中r为无风险利率，此时等于银行利率，σ为投资项目未来收益的波动率，随机过程Wt是上的几何布朗运动。

Above is me pair of such-and-such a few views and proposal, the hope can have a few helps to wiggler elder brother, doing SEO have particular risk, a lot of websites are in finish there is very long period of time after SEO do not have reaction period to be banned even, the plan that so I make still also has particular risk, before doing, Wang Shen weighs a consideration, and had made worst plan.

以上是我对某某的一些看法和建议，希望对孑孓兄能有一些帮助，做SEO是有一定风险的，很多网站在做完SEO后都有很长一段时间的无反应期甚至遭到封杀，所以我做的策划也还是有一定的风险，做之前望慎重考虑，并且做好最坏的打算。

In this paper, we contribute an evolutionary heterogeneous beliefs model byusing t distribution to replace traditional standard normal to describe fundamen-tal price process and adding risk-adjusted market fraction function in classicaltwo types traders scheme. And then we utilizedifference equation stability and bifurcation theory and numerical simulation tostudy the system. It is found that the system has some styled facts (high kurto-sis、fat tali and long memory) of the actual financial market, and this indicatesthat the simulation model can reflect well the true financial market.

本文通过引入t分布代替原有的正态分布描述基础价格过程，引入经风险调整的投资者市场分数维函数取代原有的无风险调整的市场分数维函数，在经典的两类投资者(自主投资者和图表分析者)模拟模型框架下，建立了新的异质预期资产定价模型，利用差分方程稳定性和分支理论及数值模拟的方法对该系统进行理论分析和实证研究，发现模型具有真实金融市场的程式化事实(尖峰厚尾性，长记忆性等)，模拟效果较好。

In chapter3, information is divided into two basic types, the marginal equation of bond price and short-term interest variations is established, thus the security price variations and the price equilibrium of other assets (risk security non-risk security are included) are analyzed by the implement of portfolio Theory.

第三章将债券的价格均衡划分为两大基本类型，建立了债券与短期利率变动的边际方程，运用组合原理分析债券价格变动与其它资产（包括风险证券和无风险证券）的价格均衡关系，通过比较收益原理建立了债券以市场均衡收益为折现参数的价值方程，并通过实证检验了该模型的合理性；第四章，分析了内部信息与价格的传导原理，建立了非完全信息市场条件下价格传递信息的做市商模型和预期模型，并讨论外部信息与内部信息对股票价格影响的非一致性。

In chapter3, information is divided into two basic types, the marginal equation of bond price and short-term interest variations is established, thus the security price variations and the price equilibrium of other assets (risk security non-risk security are included) are analyzed by the implement of portfolio Theory. Finally the bond value equation which takes equilibrium return as its yield Parameter is established through the theory of comparative return. In chapter 4, the intra-information and the transferable system of price is emphasized and the market-maker model and expected model under non-perfect information market conditions are established, and the disaccord of the influence of extra-information and intra-information on the security price is discussed.
