有缺陷

There are two well-known shortcomings within K-Means algorithm prevailingly used in data clustering and other center-based clustering algorithms-the number of clusters must be known beforehand and the dependence of the algorithm performance on the initialization of the initial centers.

在聚类中广泛应用的K-Means算法及其它基于中心的聚类算法有两个共同的缺陷－需要预先确定类数目且随机初始化中心引起性能不稳定。

In order to improve present state, it is necessary to initiate administrative public prosecution by the procuratorate.

Duchenne型肌营养不良症是一组由遗传因素所致的的X连锁隐性遗传病，越来越多的学者认为细胞膜的缺陷在本病中有重要地位。

It is estimated that there are about 40,000 functional genes.In order to understand those genes related to human diseases and the novel functional genes, the genetic manipulated mice including transgenic mice and knockout mice have been generated to facilitate the purpose.This transgenic core has been collaborated with industrial and research institutes for years, and has built up competitive know-how for transgenic mice, embryo cryopreservation, and pathogen free rederivation.

小鼠长期以来即为研究人类疾病最佳动物模式，2001年美国赛洛因公司已将小鼠129的两个品系之基因序列解码完成提供付费使用，2003年小鼠B6的基因序列也被Mouse Genomic DNA Sequencing Consortium解码完成，预估约有4万个功能基因，随著基因操控技术的成熟，制造出各种带不同基因缺陷的模式动物供生物医学研究已非难事。

Or more round indications in a 3870 mm2 area located at the most defective position, is rejectable

On the Unreasonableness of Renvoi Renvoi, which is unique to private international law, can neither show sufficient respect to foreign laws nor achieve enough harmony of judgments owning to its logic defects and its negligence of other countries' attitude toward it.

反致是国际私法上特有的制度，但在逻辑上有严重缺陷。它基本不考虑受致送国对于反致的态度，因而并不能体现对于外国法的尊重，也不能保障判决结果的一致性。

Nowadays the scholars of other countries have developed many algorithms,this dissertation sums up these classical traffic incidents detection algorithms and indicates that these algorithms are mostly based on other countries freeways' detection data and their main limitation is that the algorithms are lack of replantable and auto-adaptable, while our freeway has great differences with other countries in traffic flow, traffic makeup and road establishment and so on.

目前各国学者已开发出各种检测算法，本文在总结常用交通事件检测算法的基础上指出这些事件检测算法大都是基于国外道路的检测数据，且其主要缺陷表现为缺乏可移植性和自适应性，而我国道路在交通流量、道路交通组成以及道路设施等方面与国外有较大的差别，如果直接将这些方法应用于我国高速公路事件检测，检测效果不会很理想。

Acetate groups charge ZnO nanocrystals negatively and passivate the surfaces,reducing the surface defects and visible emission centers. Resultantly, the increase of acetategroups lead to the quench of visible emission and improvement of photoluminescenceproperties. At appropriate concentrations, the hydroxide groups mainly passivate the surfaceand improve the photoluminescence properties.

研究发现，氢氧化锂/醋酸锌的比值对胶体氧化锌量子点的发光性质有重要影响；醋酸根基团通过使氧化锌粒子带负电荷并钝化其表面，使得氧化锌纳米点的表面缺陷和可见发射中心大大减少，因此醋酸根浓度的增大导致了可见发光的淬灭和发光性质的增强；氢氧根基团在中等浓度时主要起钝化氧化锌表面的作用，使产物的发光性质得到改善。

As a new rodless oil production equipment, the ESPCP can be applied in high-viscosity, wax content, sand or gas content well, and radically resolve problems met by sucker rod screw pump applied in heavy oil production such as break of rod , offset-abrasion of rod tube and limit to apply in deep or deviation well .The unit also overcomes the low efficiency of ESP pumping high viscosity oil and especially applied in directional well .

潜油电动螺杆泵作为一种新型的无杆采油设备，可用于高粘度、含腊、含砂、含气原油的开采，从根本上解决了有杆螺杆泵在稠油开采中的抽油杆断脱、杆管偏磨和在深井、斜井中使用受到限制的问题，而且也克服了潜油电动离心泵输送稠油效率低的缺陷，特别适用于定向井的原油开采。

Among the helpers of the two heroines, it isn't hard to see that Shug is a more ideal helper than the others.

比较两者的帮助者不难发现沙格是理想的帮助者，而其他帮助者都有其明显的缺陷。
