不存在的

However, two kinds of problems exist in the use of the machines. One is that fibers left on doffer can＇t be reused, which may damage needles when they are accumulated for a long time, and the other is that fiber fed by carding mechanism is not in accordance with that is needed, because of the unevenness of sliver, which will finally result in the unevenness of fabric density.

目前国内外生产的人造毛皮机在使用过程中普遍存在着两个问题：一是道夫上未被织针钩取的纤维不能回收利用，时间久了积聚起来对织针和道夫针布造成损伤，影响生产；二是由于存在着喂入毛条重量不匀的问题，使织针和道夫针布喂毛机构喂入的毛纤维量不准确，从而造成织物的密度不均匀。

Only if these instable elements arrive at some level, the political instability will be changed into reality.

当然，生成和存在不稳定因素只是表明这里存在不稳定的可能性，只有当这些不稳定的因素达到一定的度，才会酿成现实的政治不稳定。

After discussing the structural conditions of the existence of the active network solutions, the state equations in normal form over F of electrical network which are suited for studying the character of network structure are derived. If there is no loop containing only capacitor and independent voltage sources, and if there is no cut-set containing only inductors and independent current-sources, both matrix A and B in ?

在探讨了有源网络解存在的结构条件下，推导了适合研究网络结构特征的多元有理函数域上电网络的范式状态方程：如果不存在仅由独立电压源和电容器构成的回路，且不存在仅由独立电流源和电感器组成的割集，则无论是有源网络还是无源网络，在网络的范式状态方程？

Three subjects about the sci-tech park construction, agriculture, entironment and technology were proposed. Some problems were pointed out, such as inaccurate localization, pool maneuverability, unscientific programming, pool drive power and incorrect relationship between the park and farmers. Furthermore, Pharisaism, without regard to economic benefits and vast government action are still serious problem existing.

提出了园区建设要突出农业、生态、科技三大主题，也指出目前园区中存在的问题，如规划定位不够准，可操作性不强；园区规划不够科学，园区的辐射带动作用不强，没有妥善处理好园区与农民的关系；存在形式主义，为园区而建园区，不讲经济效益，政府行为较重等。

软件保护中，把不能复制的标记或签名存放在软盘上的方法，用一个特殊测试程序来检测签名是否存在，如不存在，则被保护的程序不能运行。

Translation: take all this with a pinch of salt. But it's also true that you only know what you know -- and that many companies may not be aware of data leaks that had occurred, especially the roughly ten percent of respondents who either don't know how they'd find a leak if one existed, or worry that one may have occurred, but can't prove it.

采取一切，这与保留之处），但它的也是事实，你只知道你知道-而且许多公司可能不知道泄露数据已出现的，特别是大约百分之十的受访者要么不知道他们是如何帆船漏水，如果确实存在，或担心有人可能时有发生，但并不能证明它但它也是事实，你只知道你知道-许多公司可能不知道泄露数据已出现的，特别是大约百分之十的受访者要么不知道他们是如何帆船漏水，如果其中存在的，或担心有人可能时有发生，但不能证明这一点。

In this article,we will focus on the human resource present situation in ZYEU,taking present situation into consideration,arguing that the average degtree of branching is not good enough,and there has been some inconsequence in the age structure of basic staff,some of who still haven't got requisit qualification.All of these must be changed through training.But as it comes to the practice nowadays,there are many mistakes in training such as mis-understanding in training idea,lack of requisit teaching utilities,problems of training management and services,shortage of evaluation in training effeciency. Then,solutions are surggested in the thesis,for example:change the concept to confronte challenges,establish training demand analogy machanic,defuse conflicts in training with modern matheds,establish evaluation in training effeciency etc.

本文结合遵义市电力公司的实际，分析了遵义市电力公司的人力资源现状，认为目前该公司的人力资源状况存在包括员工文化程度整体偏低，基层班组人员年龄结构不尽合理，部分基层班组学历层次偏低等问题，必须通过培训来加以提高，但从目前培训的实践来看，培训又存在诸如&培训观念存在误区&、&缺乏必备的师资与基础设施&、&培训的管理和服务存在问题&、&培训缺乏效果评估机制&等问题，论文接着针对培训所存在的问题，提出了解决问题的对策，包括改变观念迎接挑战，建立培训需求分析体系，利用现代手段解决培训矛盾，建立培训效果评估体系等。

Our results show that there is no obvious conditional convergence in china, that is, given the same level of human capital, market openness and other factors the economic provinces have demonstrated an unconspicuous growth convergence.

本文研究得出，中国地区间的经济增长，存在不明显的条件收敛的特征，即在具有相同的人力资本、市场开放度等结构特征的经济地区间不存在明显的增长收敛趋势，但是存在着很显著的&俱乐部收敛&特征，即按东中西划分的区域内部人均经济产出具有明显的聚集现象。

To the question that the garden nursery of Beijing exists at present, for instance: The unordered competition still exists in the garden nursery of Beijing, nursery stock market have situation, operation mechanism of disordered state can meet development of market economy , lack long-term nursery stock plan, shoot timber structure await and improve, the quality of the nursery stock can not be got, garden nursery scientific research consciousness is desalinized , still lacks the qualified personnel in a specific field with engineering level, soil resource to consume seriously etc..

针对目前北京市园林苗圃存在的问题，如：北京市园林苗圃仍然存在着无序竞争、苗木市场存在无序状态的情况、运营机制不能适应市场经济的发展、缺乏长远的苗木规划，苗木结构有待改善、苗木的质量得不到有效保障、园林苗圃科研意识淡化、仍然缺少具有技术水平的专业人才、土壤资源消耗严重等。

To eliminate the information of the surface model, thus improving the modeling speed and enhancing precision, an algorithm based on digital image processing for generating self-adaptive density mesh from measured dense scatted points is also introduced.

模型采用离散拓扑结构，无须进行曲面分片，因此不存在子曲面片之间的拼接问题；不采用解析函数表达曲面，因此不存在复杂组合曲面的参数域界定困难的问题；模型去噪能力强，特别适合大噪声场合。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.
