At a certain range, habitat loss and its spatial structure can benefit the control of the epidemic disease, which indicates the possibility of using human disturbance in habitat as a potential epidemic-control method in conservation.(6) Not only the quantity of habitat loss but also the spatial correlations of patch types caused by nonrandom habitat loss affect the invasion and transmission of disease. More fragmented landscape (high amount of habitat loss, low clustering of lost patches) hinders the parasitic infection, which also indicates that whether the spatial heterogeneity benefits or hinders the invasion is dependent on the considered ecological process.(7) Two components of the spatial heterogeneity (the amount and spatial autocorrelation of the lost habitat) form a trade-off in determining the host-parasite dynamics.(8) Within a certain range of habitat loss, host can counterbalance the positive and negative effects, and shows a rising tendency.(9) The epidemic is more likely to break out in the prey-predator system if only a small amount of habitat loss.(10) A highly aggregated distribution of species is a common behavioral strategy when dealing with habitat loss or other environmental stresses.(11) The parasite-host/prey-predator eco-epidemiological systems have the similar mechanism with the intraguild predation systems, and the predator acts as the intraguild predation, the infected prey acts as intraguild prey, and the susceptible prey acts as shared resource.(12) Species at the highest trophic level are no longer affected the most by habitat loss, which depend not only on the biological mechanism but also on the external environmental disturbances.
随着邻体数目的增加,病毒的感染力度变得更大而且在空间上形成聚集的波形;(5)生境破坏及其空间结构在一定范围内有利于疾病的控制,这暗示人为对生境的干扰可作为疾病控制的一个潜在方法;(6)生境破坏的数量以及不同类型生境的空间分布格局都显著地影响了寄生病毒的入侵和传播,生境破碎化程度越高(高丧失斑块的数量或低聚集程度),将越有害于病毒的入侵和传播,这暗示了空间异质性是否有益于物种的入侵依赖于所考虑的生态过程;(7)由生境破坏引起的空间异质性的两个组分之间存在负偶联关系trade-off(8在适度的生境破坏范围内,宿主种群能够平衡生境破坏带来的正负两种效应并呈现增长趋势;(9)在捕食-食饵系统中,寄生感染病毒极有可能在生境破坏量较低时爆发;(10)物种在面临生境破坏或者其它环境压力时表现出更高的聚集分布策略;(11)寄生-宿主/食饵-捕食生态传染病系统与共位捕食食物网结构具有相似的生物机制,其中捕食者扮演共位捕食者的角色,已感染食饵作为共位食饵,易感染食饵扮作共同消耗的资源;(12)位于最高营养级水平的种群对生境破坏的响应不一定是最敏感的,这不仅依赖于内在的生物机制同时也依赖于外在的环境干扰。

Secondly, the quality loss model of the quality control, quality problem tracing back and the quality improvement is constructed, which minimizes the quality loss in quality control system. The quality loss model combined with Duncan model and Taguchi quality loss model is studied, the control parameters such as the upper control limit and the lower control limit are computed for the quality control in manufacturing. The Taguchi quality loss model is improved with the fuzzy theory, and the validity of the quality loss model is validated by the instance of the principal axis quality control.

In the second part of this book, I will work with you to analyze the Chinese culture and the performance of the four at a loss: the first is the Chinese people at a loss to know to make money to make money can have no sense of social responsibility and morality; the second is that we This loss of self-culture of the outside world to understand the lack of real, hard to understand but also impetuous to stay on the surface; This will lead to a third loss, that is, we rarely understand how others view us, we usually only concerned about their views at a loss, not to think about the root causes behind these views where; Fourth, more tragically, with others compared to our understanding, we are at a loss of their shortcomings and lack of recognition of the profound knowledge and self-examination.
在本书的第二部分,我会与大家一起分析中华文化的四个茫然表现:第一就是中国人就知道茫然地赚钱,为了赚钱可以没有任何社会责任感和道德感;第二就是我们这个文化茫然的自闭,对外面的世界缺少真正的理解,好不容易有所了解也只是浮躁地停留在表面;这样就导致第三个茫然,即我们也很少明白别人如何来看我们,我们通常只是茫然地关注其看法,而不去思考这些看法背后的根源在哪里;第四,更可悲的是,与别人对我们的了解相比,我们对自己的缺点是茫然的,缺乏深刻的认知和反省。

Result The results showed that the cutting survival rate and propagation coefficient were higher in interlayer scale, the difference of which was not obvious between outside and inside scales. Compared with integrated scale, cross cutting and score cutting scale all could reduce scale propagation coefficient Treating scale with 0.1% HgCl2 could prevent scale rot effectively and increase propagation coefficient Integrated scale without segmentation was good for lily bud scale cutting.
结果]结果表明:中层鳞片的扦插成活率较高,繁殖系数也较高,外层与内层鳞片之间的差异不明显;与完整鳞片相比,横切鳞片和纵切鳞片都会降低鳞片繁殖系数;用0.1% HgCl2处理鳞片,可有效防止磷片腐烂,提高繁殖系数。

In the traditional GSM network planning, the revised Hata model serves as the prototype, and the coefficient in the model formula is tuned according to the data obtained in the radio propagation feature test specific to local actual radio environment, so as to obtain the propagation model for practical prediction. A common digital map only contains the clutter information and the digital terrain model information. So the building designers cannot fully allow for the influence of radio propagation, and can only estimate the influence on the building roughly from a traditional perspective, e.g., consider the influence of different clutters through certain clutter offset.
在传统的GSM网络规划中,一般都以修正的Hata模型为原型,再利用规划软件通过导入针对当地的实际无线环境做无线传播特性测试所得的数据对模型公式中的系数进行修正而得到实际预测用的传播模型,一般使用的数字地图仅包括地物信息和高程信息,因此建筑物对无线传播的影响无法充分考虑,只能从统计意义上对建筑物的影响进行粗略的估计,如通过一定的地物偏移来考虑不同地物的影响。
