The coexistence curves and light scattering data for a critical solution of benzonitrile + octane have been reported. The critical exponents relating to the difference in the density variables between two coexisting phasesβ, the osmotic compressibilityγ, and the correlation length v have been deduced and the values were consistent with the 3D-Ising value in the range close to the critical point. The experimental results of the coexistence curves have also been analyzed to examine the Wegner correction terms and the behavior of the diameter of the coexistence curves.

1Niche construction can lead to stable coexistence of diverse genotypes in spatially structured population, which supports a stable polymorphism even without heterozygote superiority.(2)With habitat deterioration, niche construction accelerates the formation of steady polymorphism and hence impedes the harmful influences of environment on the population, which might embody a life-history strategy of organism under the unfavorable environment.(3)Niche construction results in the coexistence with alternative polymorphism through genotype-environment feedback and limited gene flow.(4)The niche-constructing organism is an active force to alter its environment and hence the direction of natural selection in order to better survival.(5)Spatial dynamics and distribution pattern of metapopulation are profoundly influenced by time-lagged niche construction.(6)Metapopulation size can reach a fixed level in the recency effect and equal weighting of time lag but is statistical stability in primacy effect, which implies the primacy effect is most remarkable.(7)The increment in the relative weightingof each generation\' niche construction and the length of time lag are significant factors for system destabilization.(8)Moderate capacity of positive niche construction benefits the metapopulation persistence.(9)The narrowing of niche breadth can decrease the metapopulation size and thereby increase the extinction risk.(10)The coupled function of time lag and niche construction make the system oscillation and generate the spiral wave, spiral-broken and circular wave in heterogeneous habitat.The spatial distributions of metapopulation and resource content are complementary due to a phase lag of their both frequencies.(12)Metapopulation persistence with niche construction depends not only on the balance between colonization and extinction, but also on the balance between the ability of niche construction and natural dissipation of habitat.(13)Metapopula-tion can survive under certain condition when the percent of suitable patches in habitat is lower than the ration of extinction to colonization.(14)Two thresholds exist in the process of transition of habitat quality dynamics from unsuitable to suitable, which include the intensity of niche construction and the initial condition of system.(15)Metapopulation size is positive correlated with the ability of positive niche construction, which means that organism or population who has strongly positive influences on their environment plays an important role to maintain the available habitat.
通过上述几个方面的研究,主要得出以下15条结论:(1)生态位构建可使空间结构种群,甚至是在没有杂合子优势的条件下,形成多种可能的稳定基因型分布模式;(2)随着环境的破坏与恶化,种群的生态位构建作用加速其较早形成稳定多态以阻碍环境对种群的不利影响,解释了有机体在不利环境下的一种生活史对策;(3)生态位构建作用通过基因型—环境反馈机制及有限的基因交流导致基因型多态的稳定共存;(4)有机体的生态位构建作用是一种积极的动力改变环境进而改变其自然选择的方向;(5)生态位构建的时滞作用对集合种群动态和空间分布产生深刻影响;(6)集合种群大小在时滞的崭新效应和等权重效应下达到一固定值,而在首位效应下达到统计稳定,表明首位效应的影响最显著;(7)首位效应下生态位构建相对权重的增量和时滞的长度是影响系统不稳定性动态的关键因素;(8)适中的生态位构建强度有利于集合种群的续存;(9)生态位宽度变窄会减少集合种群的数量从而增加其灭绝风险;(10)时滞和生态位构建的双重作用使系统产生周期振荡,并在异质性环境中产生稳定的螺旋波,破碎的螺旋波和环形波三种分布模式;(11)集合种群与资源含量的空间分布因为相滞而互补;(12)具有生态位构建的集合种群续存不仅取决于侵占率与灭绝率之间的平衡,而且依赖于生态位构建能力同其生境的自然消耗速率之间的妥协;(13)当生境中适合侵占的斑块比例小于其侵占率与灭绝率之比时,生态位构建作用促使集合种群在一定条件下续存:(14)生境斑块的状态从不适合到适合转变过程中存在生态位构建强度和系统初始条件这两个阈值;(15)集合种群的大小同正生态位构建能力正相关,意味着对环境具有较强正作用的有机体对维持有效生境起积极作用。

The model in this paper takes the form as belowThe main contents and results in this paper are as follows:In section 1, we state our main analytical results on equilibria of the above system. First, several sufficient conditions for coexistence of the steady-state are given by the standard fixed-point index theory in cone. Second, the global structure of the coexistence solutions and their local stability are established by using bifurcation theory. Third, the multiplicity, uniqueness and stability of positive steady-state solutions to this system are derived by means of perturbation theory of eigenvalues, standard regularity theory, Sobolev embedding theorem and fixed-point index theory.

It's thought that the shareholder's right consists self-profit right andcommon-profit right in company theory now,but in fact,shareholder's many rightscannot be reduced to self-profit right or common-profit right.After analysis inthis article,the shareholder's rights which are not self-profit right norcommon-profit right can be disparted into two categories,and the author named themexpectancy right and coexistence right.In this way,shareholder's right consistsnot only self-profit right and common-profit right but two new sorts ofshareholder's right,which are expectancy right and coexistence right.
现在的公司法理论均将股东权分为自益权与共益权,但事实上,股东的很多权利不能用自益权和共益权进行概括;本章经过认为分析,将不能用自益权与共益权概括的股东权分为两类,并分别将其命名为期待权和共处权,这样,股东权除了包括自益权和共益权外,又有了两种新的股东权,即期待权和共处权。

And there are encouraging signs that thinking Muslims are attempting to find a way to declare a public commitment to coexistence with the other two Abrahamic religions and to uphold the love of neighbor, even when the neighbor is of another faith. Witness the 2007 letter to religious leaders in the West, signed by 140 distinguished Muslim scholars, calling for dialogue among the faiths and for mutual respect as the foundation of coexistence.
有些让人鼓舞的迹象显示善于思考的穆斯林在企图找到办法公开承诺与其他两个亚伯拉罕诸教派别和睦共处,要坚持爱邻居的原则,即使邻居的信仰与自己不同。2007年还有140名杰出穆斯林学者签名的对西方宗教领袖的公开信,呼吁不同信仰者的对话,以相互尊重作为共存的基础。

Distinguishing from the former researches about CR service communication interruption, only spectrum handoff times exceed a certain number, communication interruption will occur. This strategy can reduce the COP of CR services.(3) Some coexistence issues between WRAN and DTV system are studiedFirstly, the network architecture, system parameters, and self-coexistence of Wireless Regional Area Network are investigated, and convergent performances among overlapping Base Station are simulated and validated. Then, a simple coexistent scenario between WRAN and Digital TV is designed to analyze the interference from WRAN BS to DTV receiver.
