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。

And I believe this may have been the case with many, who, having, for want of some such means as I employed, found the difficulty of obtaining good and breaking bad habits in other points of vice and virtue, have given up the struggle, and concluded that "a speckled ax is best;" for something, that pretended to be reason, was every now and then suggesting to me that such extreme nicety as I exacted of myself might be a kind of foppery in morals, which, if it were known, would make me ridiculous; that a perfect character might be attended with the inconvenience of being envied and hated; and that a benevolent man should allow a few faults in himself, to keep his friends in countenance.

他们为了缺乏一些什么，和我所用的方法一样，等到得到好习惯和破坏恶习惯的困难，就抛弃了善恶的竞争，而结论说是「一把有几处白光的斧面是最好的斧头」，也可假藉一些理由，因为有些东西时常向我建议说，如自我期许的极端细密也许是道德上的蠢事，而如果他人知道了，会让我成为可笑的人了；而一个完美的人格必将受到嫉妒和憎厌；所以有善心的人必得在身上留一些缺点，以保留他朋友的面子。

Dynamic reliability under Littlewood-Paley wavelet is the biggest, dynamic reliability under modified meyerwavelet and harmonic wavelet are close. Analyzing the dynamic reliability of structure under odd exponent wavelet is very simple, it doesn't calculate Power Spectral Density function integral, it is only to calculate the square of displacement standard deviation and the square of velocity, then the dynamic reliability of structure can be concluded by max distribution. In addition the effects of upper limit is considered, when upper limit is smaller, the dynamic reliability of structure is less, that is, the damage possibility is bigger.

通过结构地震反应在小波基下的动力可靠性分析说明：无论是单自由度还是多自由度从理论上推导在这四种小波下的结构动力可靠性是可行的，而且考虑的结构地震反应都是非平稳的高斯过程，方法实现也比较容易；在Littlewood—Paley小波基下求得的结构的动力可靠度比较大，由改造的meyer小波和谐波小波求得的动力可靠度略有差异；单边指数小波下的结构动力可靠性分析非常简单，不用求功率谱函数来积分，只需求得结构地震反应的位移方差，速度方差，利用最大值分布公式就可得到结构的动力可靠时程；另外也考虑了超越界限对结构动力可靠度的影响，超越界限越小，结构的动力可靠度越小，即破坏概率越大。

Nowadays in India, the true orthodox Buddhism has been completely extinguished with only a few superficial appearances left, and the substance has been replaced by the non-Buddhist tantrism of couple-practice. About Theravada Buddhism, although it can still keep the appearance of sound-hearer Buddhism and is not defiled by the non-Buddhist tantrism, it is rare to find the saints who can personally realize the sound-hearer liberation now. As for Mahayana Buddhism, there are only Buddhist rituals and the mind-consciousness dharma now in China, which has just recovered from the ravage of the Cultural Revolution. In both Japan and Korea, only the appearance of Buddhist rituals but not practice remains and there is no even the mind-consciousness practice like in China. Therefore the practitioners in China, Japan and Korea cannot touch the real content of the practice and realization to fulfill the Buddhahood way of the great-vehicle Buddhism.

现存的佛教，在印度已经完全灭亡，只余极少数人保留著佛教的表相，本质已是坦特罗双身法的非佛教了；南传的小乘佛教教域，虽然仍能维持小乘声闻佛教的表相而不被坦特罗双身法的非佛教所染污，然而能够实证声闻解脱道的圣者亦已难可觅得；而北传的大乘佛教教域中，中国才刚从文化大革命的破坏中恢复了仪式表相及意识境界的佛教，日本、韩国则只剩佛教仪轨的表相而无修行的表相，已谈不上如同中国地区意识境界的修行了；是故中、日、韩对於大乘佛教实践菩萨道的见道与修道真实内涵，都已经都无力触及了。

Results In vitro recovery of the probe was mainly influenced by the perfusion rate. When the perfusion rate was set at 1.0μL/min, in vitro and in vivo recoveries of the probe were 50.16±2.34% and 14.096±0.58%, respectively. The enhancement indexes for 3%, 5% mentha oil were 3.8 and 17.6, respectively. The enhancement indexes were 9.2 and 24.8, for 3% and 5% of Azone, respectively. Conclusion The steady sate flux of meloxicam in rats is significantly improved by enhancer mentha oil and azone.

The results indicate that [(L 1) 2SnEt 2] can selectively bind to the N 1 atom of the base and the phosphate oxygen atom of AMP and may further destroy the helical structure of DNA, while the dimethyltin compound of 1,3 dimethyl 4 acetyl 5 pyrazolone [(L 1) 2SnMe 2] merely binds to the the phosphate oxygen atom of AMP and causes the contraction of DNA helical structure.

结论3 二甲基 4 乙酰基 5 吡唑酮的二乙基锡配合物(L1 ) 2 SnEt2 可与AMP 的碱基N1 和磷酸根氧原子螯合并可能会破坏DNA 的双股螺旋结构；而二甲基锡配合物(L1 ) 2 SnMe2 易与单核苷酸的磷酸氧结合，难以与单核苷酸的碱基氮原子稳定结合且只引起DNA 双股螺旋的收缩

But, if I may even flatter myself that they may be productive of some partial benefit, some occasional good; that they may now and then recur to moderate the fury of party spirit, to warn against the mischiefs of foreign intrigue, to guard against the impostures of pretended patriotism; this hope will be a full recompense for the solicitude for your welfare, by which they have been dictated.

如果我们在一个称职的政府领导下保持团结，在不久的将来，我们就可以不怕外来干扰造成的物质破坏；我们就可以采取一种姿态，使我们在任何时候决心保持中立时，都可得到它国严正的尊重；好战国家不能从我们这里获得好处时，也不敢轻易冒险向我们挑战；我们可以在正义的指引下依照自己的利益，在和战问题上作出抉择。

今天才看到了晴天，周一和周二我在惠州审核，本来这里工业比广州市少，所以空气比广州好些，可过了台风之后，空气更好些，当然还是和我家乡的天是没法比的，不过少见的蓝天和白云看着也很舒服了，台风固然不好因为会破坏很多设施而带来大的经济损失，但长期笼罩在珠三角上空的的污染物也带走了许多，让生活在这里的人们也享受了几天不做吸尘器的味道。
