有缺陷

It seemed a good plan at first blush, but there were still some defects in it.

初看这似乎是个好计划，但它仍有一些缺陷。

The characteristics of pentacene/perylene derivatives based organic solar cells are investigated in this thesis Donor and acceptor layers are pentacene and N N'-dioctyl-3 4 9 10-perylenetetracarboxylic diimide (PTCDI-2~13C) respectively Twelve organic solar cells with pentacene/PTCDI-2~13C heterojunctions were fabricated to study the influence of various alkylic perylene derivatives on the power conversion efficiency Under the sunlight simulator with AM1 5G filter and 100 mW/cm2 the solar cell of pentacene/PTCDI-7C heterojunction with cathode of Ag/Al bilayer has the best performance among the devices with pentacene/PTCDI-2~13C heterojunctions In PL spectrum analyses the pentacene/PTCDI-7C film had lower recombination rate than the other pentacene/PTCDI-2~13C films; therefore more excitons could reach the P/N junction and enhance short-circuit current Furthermore the PTCDI-7C film grown on the surface of penatcene was more matched than other PTCDI films analyzed by the PL peak shifts of 10 nm and 45 nm thick PTCDI-2~13C and images of atomic force microscope More lattice match between the films of pentacene and PTCDI resulted in fewer defects in P/N junction and more carries can reach electrodes Accordingly the power conversion efficiency approach 2% was obtained from the solar cell with the active layer of pentacene/PTCDI-7C

本研究探讨以五环素/骈苯衍生物异质接面太阳能电池之特性，利用pentacene作为电子施体有机材料，PTCDI -2C~13C作为电子受体有机材料，制作出异质接面为pentacene/ PTCDI-2C ~13C等12种有机太阳能电池，比较不同碳数的骈苯衍生物对於有机太阳能电池之光电转换效率之影响。在AM1 5G、100 mW/cm2的模拟太阳光下，以pentacene/PTCDI-7C异质接面太阳能电池具有短路电流9 882 mA/cm2、开路电压0 376 V、填充因数0 523及光电转换效率达1 945%，皆比其他pentacene/PTCDI-2C ~13C异质接面太阳能电池来的大。由薄膜分析可知PTCDI-7C在这12种太阳能电池中具有较低的电子电洞复合发光效率，可以让较多激子到达异质接面进行电荷分离，减少电子电洞对复合发光的机率；此外，由光激发萤光光谱之峰值位移配合原子力显微镜表面结构图，可以得知当PTCDI-7C成长在pentacene上时会顺著pentacene的结构成长薄膜，故较无缺陷产生在P/N接面处；而在其他结构下则无此现象产生，致使在pentacene/PTCDI-7C薄膜中的载子有较大的机会可以移动至电极，使光电流提高，进而使光电转换效率提高。

Some early theoretic methods are successful to research photoionization as well as its inverse, but it can't catch up with the development of atomic and molecular physics.

虽然早期的理论方法对研究光电离及其逆过程有很大的成功，但也存在很大的缺陷，不能满足目前原子分子物理学发展的需要。

Beijing Real Estate and Construction Bar Association Professional Committee of Liu Hua, deputy director of the Law Society: The contract agreement in the area, it seems to me there are at least two flaws: First, it agreed to construction area for the sale area, construction area is passed and the pool area and the area, and in this contract on the pool area also lacks transparency, developers will not tell you specific assessments where the location of the area, the specific area is the number, which for him provided an opportunity for fraud; Secondly, the contract agreed by the parties, permit the forecast area of 3% error, if the pool size increases as long as no more than 3%, you can only increase the pool for this increase the size back the principal.

北京地产及建造界律师协会专业委员会刘华副主任律师公会：合同协议，在该地区，在我看来至少有两个缺陷：第一，它同意建筑面积的销售区，建筑面积是通过和游泳池区和地区，并在此合同的游泳池也缺乏透明度，开发商不会告诉你具体评估那里的位置，面积，具体领域是的数目，这为他提供了一个机会，欺诈；其次，该合同约定，允许预测面积的3 ％的错误，如果池大小的增加，只要不超过3％，你只能增加池的大小增加本金。

Besides, it reveals some shortcoming of the definition of bildungsroman by analyzing the specific property of H.Hesse' s works.

除此之外，对黑塞成长小说艺术个性的分析，也暴露出既有成长小说定义的若干缺陷。

Therefore in recent, the research about bilinear mapping based group signature is also at a start stage, there are no a bilinear mapping based group signature scheme obtains common recognition. There are some design defects in existing schemes, and the security is not very ideal.

所以目前基于双线性映射的群签名还处于一个起步阶段，还没有一个有代表性的基于双线性映射的群签名方案，而现有的一些基于双线性映射的群签名方案的设计缺陷较多，且安全性较差。

Bill broker"s system of our country has a lot of questions, mainly: Bill broker system law, regulation, management organization and functionare imperfect in construction; The current operation mode is backward, is difficult to meet the development of network economy and securities market; Besides, bill broker" s incentive mechanism, management system of inside and risk management are serious defect and insufficient.

我国证券经纪人制度建设目前存在许多问题，主要有：证券经纪人制度法律、法规和管理机构、职能建设不健全：现行运作模式落后，难以适应网络经济和证券市场的发展；同时，在证券经纪人激励机制、内部管理制度及风险管理方面均存在严重的缺陷和不足。

We will tell about an experimental treatment for a birth defect.

There are 4 reasons leading to it: firstly, stimulated by the interests, the standards of selecting the news by the journalists and editors is not measured by its social value and real meaning but only to catering to the a audiences psychological needs seeking for the bizarreness etc.

这主要有四个方面的原因：第一，由于利益的驱使，记者编辑选择新闻的标准不是其社会价值和现实意义，而仅仅为了迎合某些受众新文化报等的心理需要；其二是新闻工作者求真求实精神的缺失，在采访过程中不对事件进行深入调查，认真核实细节情况，而是道听途说、捕风捉影、主观臆测；第三是由于职业构成和行业管理制度的缺陷，新闻记者素质水平良莠不齐，缺乏高度的职业使命感和历史责任感；新文化报是坚守新闻真实性原则的监督和惩戒机制缺失，导致新闻记者职业道德底线屡屡失守，防线每每突破，假新闻层出不穷。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
