同质的

Homogeneous or heterogeneous base material is selected; an alternately superimposed barrier layer and an alternately superimposed recessed layer are grown and formed at the extension of the base material; donor impurity and acceptor impurity are doped in the interface between the barrier layer and the recessed layer and in the interface between the recessed layer and the barrier layer, and the p type group III nitride material doped at a position selecting superlattice is obtained.

选择同质或者异质的基质材料；在基质材料上外延生长形成变换叠加的垒层和阱层，在垒层与阱层的界面和阱层与垒层的界面掺入施主杂质和受主杂质，得选择超晶格位置掺杂的p型III族氮化物材料，其中，每个生长周期的步骤为：生长带隙较宽的垒层，同时掺入受主杂质；生长施主杂质或受主杂质δ掺杂层；生长非掺的带隙较窄的阱层；生长受主杂质或施主杂质δ掺杂层；在N 2 气氛下对所得的选择超晶格位置掺杂的p型III族氮化物材料退火，即得目标产物。

This paper analyses the homogenous tendency of open-end fund at first,pointing out that unperfect development of market and investors' immature investment opinions is the origin of such phenomena. Secondly,having compared the fund sizes and purchase fee rates of 25 open-end funds in China,conclude that there are problems of diseconomy of scale and indistinctive relativity between fees and achievement in Chinese open-end funds. Then this paper introduces benefit and cost function to analyze the problem of lack of motivation and constrain mechanism towards fund managers because of unreasonable fees in China. Thirdly,this paper analyze funds managers' normal hazards by static game model,and then points out fund managers have serious tunneling behaviors in Chinese open-end fund industry. In the end,this paper analyzes the causes of liquidity risk of open-end fun and the particularity of liquidity risk of open-end fund in China,and concludes that liquidity risk in Chinese open-end fund industry is higher through calculating the rates of share change and comparing the portfolio selections of top 20 open-end funds in China.

本文首先分析了我国目前存在的基金产品同质化现象，指出市场发展的不完善以及投资者投资理念的不成熟是同质化的根源所在；其次对比了我国现有的25只开放式基金的规模和申购费率，得出了我国开放式基金存在着规模效应不明显以及基金业绩与费率相关性不强的问题，并引入效益函数和成本函数分析了由于我国开放式基金费率不合理引发的基金管理者激励约束机制缺失的问题；再次，应用静态博弈模型分析了基金管理人面临的道德风险，指出目前我国开放式基金由于监管机制脆弱而存在着较为严重的管理者利益输送行为；最后，分析了开放式基金流动性风险的形成原因以及我国基金市场流动性风险的特殊性，并通过计算目前我国基金资产规模前20位的开放式基金的份额变动率以及比较它们的投资组合结构，得出了目前我国开放式基金流动性风险偏大的结论。

Keeping［element］/［Mg］concentration ratio lower than 0.05 can minimize isobaric interference and matrix effects.

控制［元素］/［Mg］的浓度比在0.05范围内，可以忽略同质异位素的干扰和基质效应。

During the past long period, much progress has been realized on the study of the retrieval of LST based on remote sensing, and many algorithms for the LST retrieval have been developed. However, in these algorithms non-isothermal mixed-pixels are all treated as an isothermal and homogeneous surface, which caused directly the results that the LST obtained by these algorithms is only an average temperature of mixed-pixel.

在过去很长一段时间里，地表温度的遥感反演取得了长足的进展，发展了大量的反演算法，但是这些算法都把普遍存在的非同温混合像元视为同温同质体，直接导致反演所得的只是物理意义模糊不清的混合像元的平均温度。

The models of homogeneity and function morphism, is emerging constantly, it is the cell-phone rejected only that floods the market first, while the trade company is immersed in the profit is puzzled and consumers are enjoyable, some producers introduce colors and reject the cell-phone one after another , the cell-phone market is crowded with people at one time, the producer reaps fabulous profits by this too.

同质同功能同型的机型，不断涌现，先是单屏的手机充斥市场，在商家沉浸于"利惑"和消费者还来不及过瘾的同时，一些厂家纷纷推出彩屏手机，一时间手机市场上人头攒动，厂家也借此大捞一把。

The mineralization-alteration in Shuangfengshan appears in downward succession of silica breccia zone, low grade gold-bearing silica rock zone, quartz stockwork zone, pyrite montmorillonite zone and propylitic alteration zone.

The main problems include the unbinding of the coordination system and area planning agreements, redundancy construction of infrastructure, and the unnecessary competition inside the area.

其发展面临着协调制度及协议规划的约束力不够，交通设施存在重复配置，产业同构、同质竞争现象严重等问题。

The quality including reliability, voltage and service for electricity commodity is described in this paper.

按市场经济原则对近期和远期电力这种特殊商品的内容、不同电力商品的质量、价格进行分析，提出电力商品的质量应包括可靠性、电压质量和服务质量；近期我国应按发、输、配、用4 个环节界定供需关系和电力商品，电价机制也应与此相适应，由于相关条件不同，&同网同质同价&应视具体情况确定。

In this thesis, using maize of same nucleus but different cytoplasms and same cytoplasm but different nuclei as the experimental materials, RNA editing of mitochondrial atp6 and cox2 gene in different tissues was analyzed.
