不稳定

So welfare opportunities are a significant determinant of family instability in poor neighborhoods, but this is not the result of AFDC regulations that exclude most intact families from coverage .

所以福利机会在贫困社区是使家庭不稳定的重要的决定性因素，但家庭不稳定并非将多数完整家庭排除在未成年子女家庭补助之外这一制度的结果。

A methodology of noise-like key generation is presented. Chaotic process of tentmap function is used as a deterministic generation of noise-like key, image storage and retrieval are completed in a algebraic form. A mathematics model of noise-like chaotic coding memory is constructed, meanwhile the basic mechanism of circulant convolution and circulant correlation in image information storage and retrieval are demonstrated.

在详细阐明数字序列和字母序列的1-D映射函数设计方法的基础上，利用构造出的1-D映射的稳定周期环和不稳定极限环完成了存储和联想记忆功能，为了识别有关的输入信息，提出了映射函数直接控制的方法；在此基础上，提出了一种1-D映射型混沌神经网络模型，该网络本身不当作一个"黑箱"处理，网络的参数值由网络中实现的映射函数来确定，该网络模型具有联想记忆、容错性、模式识别和奇异滤波等一系列智能信息处理的基本功能。

By analyzing the distribution of the zeros to the transcendental characteristic equation associated with the trivial.solution,we obtain some- sufficient conditions on the stability and instability of the trivial solution.These results are generalized to n-unit neural networks by means of space decomposition in this Chapter.

在第二章中，我们讨论了不带自反馈与带自反馈的3元环状神经网络系统平凡解所对应超越特征方程的根的分布情况，确定了系统平凡解稳定与不稳定的充分条件，并利用空间分解的方法把相应的结果推广到n元环状神经网络系统。

This new strategic reality may be understood as another form of the bipolarity of global powers seen during the Cold War.

新的战略现实可以被理解为冷战期间世界两极力量的另一种表现形式，世界现在不是被分割为两个超级大国所控制下的区域，而是被分割为相对稳定的、有秩序的、繁荣的、相互联系和相互依赖的区域--也就是主要在欧亚大陆的大部分地区、亚洲的东北和东南部以及北美地区的所谓全球化国家--和相对不稳定的、无秩序的、经济衰退的、国家之间较少相互联系或相互依赖的地区，包括亚洲的东南部一部分、南亚和中亚、中东的大部分地区，撒哈拉以南非洲，以及加勒比海和拉丁美洲的部分地区。

In terms of the synoptic environment and precipitation characteristics, there were some common characteristics in these two cases. For instance, warm and moist air with the conditional instability atmosphere in the lower troposphere, it was associated with the highest equivalent potential temperature gradient and strong moisture contrast to below 700 hPa. The lower-level convergence was the major produced mechanism of MCS and the low-level southwesterly flow generated convective instability.

从综观环境条件与降水特徵显示，两个案共通特徵包括（1）低对流层属暖湿条件性不稳定大气，（2）最大相当位温梯度以及水气梯度分布於700 hPa以下，（3）低层辐合均为个案中MCS之重要激发机制，（4）有明显低层西南喷流，大气呈现对流性不稳定状态，（5）中层短波槽线的移入，以及（6）高层辐散分流场的存在，提供MCS发展的有利环境条件。

It was shown that when the production function was constant return to scale, the model became a A-K model; when the production function was increasing return to scale, the equilibrium point was unstable; when the production function was decreasing return to scale, the equilibrium point was a saddle.

结果发现：生产函数为规模收益不变时，模型简化为A-K模型；生产函数为规模收益递增时，均衡点为不稳定结点；生产函数为规模收益递减时，均衡点为鞍点稳定。关键词：数理经济学；经济增长；政府支出；生产效应

This is a part of the destabilization that takes place when you have the kind of conditions that you do now in Lebanon thanks to Syrian interference.

她说：这是造成不稳定的部份原因，叙利亚干预黎巴嫩就创造了这种导致不稳定的条件。

During aging, Gastel index which is sensible to aging condition decreased with increase of aging temperature and aging time. As the same time, the exponential relationship between the change of viscosity and aging time was discovered. Both the gastel index and the aging index can be used to evaluate the aging resistance of the colored paving asphalt.

彩色沥青老化过程中，沥青胶体不稳定指数对沥青老化条件很敏感，随老化温度的升高和老化时间的延长而增加；粘度随老化时间的延长近似呈指数关系增加，所以可以用胶体不稳定指数和老化指数来评价彩色沥青的老化性能。

We analyze the principle of stick-slip motion deeply. From foregoing analysis a result was made that dry friction is the main factor in influencing low speed capability of electro-hydraulic servo system. Dry friction must be compensated for improving the low speed performance. Then a nonlinear model with friction is set up and control methods is discussed.

深入分析了汽轮发电机转速不稳定的原因是由于电液伺服系统在低速区性能不稳定，而影响电液伺服系统低速性能的主要因素是干摩擦，要提高电液伺服系统的低速性能必须对摩擦力进行补偿。
