The results showed as follows:(1) the de-farming index of 479 investigated farm households is 79.21% with per capita area of de-farming slope farmland of 0.205 hm~2,per capita grain yield loss resulted from de-farming slope farmland of 74 kg and per capita allowance of 171 yuan from the government in 2003;(2) the de-farming allowance from the government has a bigger influence on a poor household,and if an allowance from the government would be stopped,the re-exploitation of partly de-farmed slope farmland is possible;(3) in 2003,per capita cash income of 479 investigated farm households is 1 492 yuan,and its sources mainly from floating employment,selling grain and greenstuff,de-farming allowance,selling products of domestic livestock and poultry and dealing dicker etc.;(4) in a few coming years,those employments of stable and higher earning will be firstly selected by farmers,and high expected value agriculture or rural commerce are going to become the leading livelihood of a good few farmers with some fund or skill.

结果表明：被调查农户人均退耕坡地0.205 hm2，退耕指数达79.21%；2003年479农户因退耕导致的粮食减产量人均74 kg，得到政府补贴人均171元；退耕补贴对贫困农户的影响程度较大，停止退耕补贴后存在反垦可能性。2003年被调查农户人均现金收入1492元，主要来源于外出打工、卖粮菜、退耕补贴、卖畜禽产品和做小生意等。未来几年，能获得稳定收入且报酬相对较高的行业是农民谋生的首选，有资金积累或一定技能的农户正在将生计转向高附加值农业或第三产业。

It is found that the gender imbalance tends to stimulate and aggravate the existent risks in aspects of population, society, economy, public health, culture, etc. The macro social risks lead to an increase in individual and group anomie of marriage, family, sex and so on at different levels. Macro social risks and micro anomie will threaten public security and social stability.

研究发现：性别失衡将刺激并加剧既有的人口、社会、经济、健康、文化等一系列风险；在性别失衡下的宏观社会风险影响下，个体与群体在婚姻、家庭、性和其他方面存在着不同程度的行为失范问题；宏观社会风险与微观行为失范将威胁公共安全与社会稳定。

A social order of stability symbolizes healthiness degree of any society.

稳定的社会秩序是一个社会健全程度的标志。

The effects of different host plant on the stability of plasmid in HA 12-1-12 and HA 7-2-2 were also assessed.

进一步考察了其中两个菌株HA 12-1-12和HA 7-2-2的质粒在四种宿主体内的稳定性，结果表明HA 12-1-12在不同宿主体内高度稳定，HA 7-2-2却发生了不同程度的变异，得到10个变异株。

Large current glow discharge has a strong tendency to transform to arc discharge. This paper focuses our attention on the factors affecting the stability of large current hot cathode glow discharge. The research results show that the cathode temperature, the cathode surface state and the size and place disposition between cathode and anode have influences on the stability of glow discharge, respectively.

大电流辉光放电具有较强的向弧光放电转化趋势，本文研究了影响大电流热阴极辉光放电稳定工作的因素，结果表明，阴极温度、表面形貌、阴阳极位置和尺寸配置关系等对辉光放电的稳定性均有不同程度的影响。

Therefore, the aim of these treatments is to provide a mature, stabilized organic material in which the humification process,Which typically occurs under natural soil conditions, has started and has reached an adequate degree with the production of "real" humic substances.

因此，这些处理的目的就是要提供一个成熟的稳定的有机物质，在其中腐殖化作用（自然土壤条件下的典型现象）已经发生而且已经达到一个足够的程度，能产生真正的腐殖质。

The GFAP is a specific marker of astrocyte, its expression is more higher in the activity astrocyte, and finally the GFAP become the main composition of scar formations. The S -100 is a kind of acidity, dissolubilites, low molecular quantity and calcium hydronium conjugated protein, and it is mainly existed in neuroglial cell and schwann cell. It can promote the growth of axon, glial hyper-plasia and nerve divide and calcium's stability inside of cell, thus regulatin g the shape and metabolism of astrocyte . The quantity of S -100 protein and the degree of ischemia have direct proportion .

胶质纤维酸性蛋白是星形胶质细胞的特异性标记物，在活性星形胶质细胞中GFAP的表达相对更高，且最后GFAP成为胶质疤痕的主要成份。S-100蛋白是一种酸性、可溶性、低分子量的钙离子结合蛋白，主要存在于胶质细胞和雪旺细胞中，它可促进轴突生长、胶质增生、神经分化和细胞内钙的稳定，从而调节星形胶质细胞的形态和代谢。S-100蛋白与缺血的程度是成正比的。

Mercer wants the strategy to be low volatility with a stable return profile for which ILS are ideal.

默瑟希望的策略，有了一个稳定的回报程度低波动的混的理想选择。

The experimental results indicate that the LMBP neural network has higher classification rate, more rapidly converge velocity by comparing with other improved BP algorithm and the Radial Basis Function neural network. Through the experiments of recognizing the sonar image polluted with Gaussian noise, it is proved that the LMBP neural network has good stability and better anti-noise performance.

通过与标准BP算法和几种常用改进型BP神经网络以及径向基函数网络比较，验证了用LMBP神经网络作为声纳图像识别系统中的分类器，能够提高图像的识别率，加快网络的收敛速度，通过对受不同程度高斯白噪声污染的声纳图象的识别，验证了其性能稳定，具有较好的抗噪声性能。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
