But our country's present social security system actually has the hindrance function to the occupation mobility, the main performances are as follows: Two units social security system, the unequal tax revenue system in the social security, social security singleness in view of the impoverished social class, hardly carried and transferred characteristics of social security system , ignoring benefits protection of mobile staffs, lack of social security legislation , slow development of service system of social security ,lack of policies and measures on promoting regional motilities insocial security system.

但是，我国现行的社会保障制度却对职业流动有着一定的阻碍作用，主要表现为：二元的社会保障体系的存在，社会保障体系的便携性、可转移性较差，忽视流动职工的利益保护，社会保障立法的缺失，社会保障服务体系发展缓慢，社会保障中税收体系的不平等，针对贫困阶层的社会保障单一，社会保障体系缺少促进区域流动的政策与措施等方面。

Due to the fact that the intercarrier spacing in OFDM is relatively small, OFDM transceivers are somewhat more sensitive to phase noise compared to single carrier transceivers. Thus this problem must be carefully considered in designing an OFDMbased system since an accurate prediction of the tolerable phase noise can allow designer to relax system specifications. According to spectrum theorem, two components of phase noise were analyzed: common phase error and intercarrier interference. On the basis of the analysis, the performance of OFDM was given for the case where phase noise has been added to the signal, and an optimal design criterion for OFDM parameters was proposed that allows to improve the phase noise error correcting capabilities in OFDM receiver.

由于采用子载波间相互正交的结构，OFDM系统对于由本地振荡器不稳定性所导致的相位噪声影响非常敏感，针对公共相位误差CPE和载波间干扰ICI两种影响表现形式不同的干扰项，从功率谱密度函数这一独特角度分析了相位噪声对OFDM系统性能的影响，提出了旨在提高接收机抵抗相位噪声能力的OFDM系统关键参数优化与设计准则，可在对所设计OFDM系统性能加以提高的同时，有效降低对接收机前端模拟振荡器件和相位噪声抑制单元的性能指标要求，从而降低接收机硬件实现成本。

As an aesthetic category, game is, no doubt, very important in its relations with many basic questions. So far as its many manifestations as shown in different theoretical systems are concerned, game, as a category, is vague in form; it is often used as a tool to explain theories and it is characterized by its metaphoricalness when elaborating.

Firstly, an invasive species must be invasive enough in itself or has some biological distinction, such as quantitative and qualitative differences in the genome, or patterns of recombination. Secondly, to invade successfully, a new environment for an invasive species must be invasible, and this we may call the ecological basis of invasion. An invasive species may need to establish new interactions with other species, especially those mutualistic relations such as animal related pollination, seed dispersal by animals, mycorrhizal fungi, and symbioses between plants and nitrogen fixing bacteria.

首先从其自身来说，需要有足够的入侵性，这可以认为是入侵种的生物学基础，可能表现为具有多倍性、一定的遗传变异、杂合性或表型可塑性，以及不同的交配系统等；其次一个物种的入侵成功还取决于入侵生境的可入侵性，这可以认为是入侵种的生态学基础，而新的种间关系的形成，尤其是入侵种与其他种类的互惠共生关系的建成是关键。

The record qualitatively shows that overall U.S. consumer spending tends to be stronger in the early stages of an El Nifio. This may be due partly to, and initially from, less nondiscretionary spending on energy, for example, and more spending on other discretionary items. Moreover, it takes about 912 months for the impact of the warming in the Pacific Ocean (as reflected by the Southern Oscillation Index) to show up as abnormally wet weather over a widespread area of the United States. The sunspot cycle might be another reason for expecting longer-run impacts climate on the economy. Galileo was credited with discovering sunspots around 1610. Ever since that time, there has been a debate, which at times has been intense, on the effect of solar activity on man, weather, agriculture and the whole economy.

Asked by Medscape Oncolo gy to comment on this finding, Jayne Franklyn, MD, PhD, from Queen Elizabeth Hospital, in Birmingham, United Kingdom, who was not involved with the study, said:"This is an important study, as it involved a large number of patients with a relatively rare form of thyroid cancer, specifically looking at those with the sporadic or noninherited variety of this cancer, and it presents the intriguing possibility that the presence of the mutation is associated with a prediction of tumor behavior and therefore prognosis."

The somatic hybrids usually showed specific bands and combined all the bands of both parents. In combinations, some new bands were detected, and occasionally specific bands of parents were lost, which indicated that chromosome recombination and exchange happened after fusion. Additionally, in some combinations, specific bands from leaf parent were detected, which revealed the plants were of putative hybrid origin, because leaf protoplast cannot redifferentiate by both single culture and co-culture.

体细胞杂种一般表现为具有双亲的特征带，且综合双亲的所有带，但在部分杂种中检测到了双亲都没有的新带，也发现有丢失亲本的特征带或共有带的现象，说明融合后染色体发生了重组和交换；有的引物只检测到叶肉亲本的特征带，根据柑橘叶肉细胞无论单独培养还是共培养均不能再生的事实，可推测其为体细胞杂种或二倍体叶肉亲本型胞质杂种。

The other two groups are longan and'Longli, a special germplasm', which is a natural hybrid of litchi and longan. The results from RAPD analysis also showed that longan might be the maternal parent and the extremely early maturing litchi types be the paternal parent since'Longli'is closer to longan in the taxnomy. This information would be useful in the distant crossing breeding to fruit of Sapindaceae family.

Diagnosis/testing. A diagnosis of ocular albinism is probable in the presence of congenital nystagmus, iris translucency, and significant hypopigmentation of the ocular fundus periphery in males with normal skin pigmentation and foveal hypoplasia, reduced visual acuity, and aberrant optic pathway projection, as demonstrated by crossed asymmetry of the cortical responses on visual evoked potential. X-linked inheritance is documented by either a family history consistent with X-linked inheritance or the presence of typical carrier signs (irregular retinal pigmentation and partial iris transillumination) in an obligate carrier female.
