不存在

It also applies kernel density estimation method to investigate the accumulative relative productivity and the dynamic evolvement of its distribution. The result shows that there exists no country level absolute convergence of the provincial productivity whether incorporating environmental factors or not. The provincial TFP index is in a divergence trend and the provincial technical efficiency index has a convergence trend when incorporates environmental factors.

无论是否考虑环境因素，代表东、中、西三大区域的虚拟变量均不显著，表明不存在俱乐部收敛；当所考虑的控制变量为基础设施水平、工业化水平、经济开放度、能源强度时，所有的控制变量皆不具有统计显著性，表明不存在条件收敛。

Simons [30] proved the non-existence theorem for stable integral current in acompact Riemannian submanifold isometrically immersed into a unit sphere andvanishing theorem for homology groups. In 1984, Y. L. Xin [47] generalized theLawson-Simons nonexistence theorem for stable integral current and vanishingtheorem for homology groups to the case of compact submanifolds in Euclideanspace, and gave several important applications.

Simons运用Federer-Fleming存在性定理[19]和几何测度论中变分技巧证明了单位球面中紧致黎曼子流形上稳定积分流的不存在性定理和同调群消没定理[30]。1984年，忻元龙将Lawson-Simons稳定积分流的不存在性定理和同调群消没定理拓广到了欧氏空间中紧致子流形的情形，并给出了若干重要的应用[47]。1997年，K。

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？

Then, one class of second-order semilinear differential systems with two parameters is considered.

第五章，用锥上的Deimling不动点定理分别讨论了依赖于参数的一阶中立型泛函微分方程和一阶中立型泛函微分系统，导出了一阶中立型泛函微分方程以及一阶中立型泛函微分系统存在两个正周期解，存在一个正周期解以及不存在正周期解的充分条件。

Subindex as the proxies of the stock price.The results show that(1) there is no long equilibrium relation between the stock price and the performances of the listed companies,that means the movements of ...

研究发现：①股票价格与上市公司业绩变化之间不存在长期均衡关系，说明股票价格不反应上市公司业绩；②沪市指数和深市指数之间存在长期均衡关系，并且沪市指数是深市指数的G ranger成因；③沪市上市公司净资产收益率和深市上市公司净资产收益率之间存在长期均衡关系，不论是从长期还是短期来看两者都呈同向变化关系。

What everyone said did not exist must exist. For example, suppose Wang Er didn't exist, then where's the name Wang Er from?

大家都说不存在的东西一定存在，比如王二，假如他不存在，这个名字是从哪里来的？

Structure index was significantly (P.05) different among three plant species whereas channel index and enrichment index were not. Plant species not only modified abundance of plant-feeding, omnivorous and predatory nematodes, but also percentage of each trophic group. Bacterivorous and fungivorous nematodes were affected most by the differences in plant species.

研究表明在沙地生态系统中，3种植物根际土壤线虫群落的多样性、丰富度、均匀度和线虫总数虽然都存在一定的差异，但不显著；功能多样性指数中结构指数存在显著差异，而通道指数、富集指数不存在显著差异；3种植物对根际土壤线虫群落中各营养类群线虫的比例有显著影响。

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。

If the act of conversion is not to become a mere process of substitution, as in sleight-of-hand performances, the terminus ad quem must unquestionably in some manner newly exist, just as the terminus a quo must in some manner really cease to exist.
