Although there is enough grain to go round at the moment, you do not need to be a neo-Malthusian to worry about the demand implications of a global population rising by about 80m people a year or to notice that countries with fast-growing populations – India, the Philippines and Egypt, for example – are especially vulnerable to disruptions in the world's food trade.
虽然现在还有足够的粮食分给大家，但你不必是一名新马尔萨斯主义者，就会担心全球每年增加8000万人口对粮食需求的影响，或者注意到人口迅速增长的国家尤其容易受全球粮食贸易动荡的影响。
Chapter one summarizes the essential framework and the frontiers and development of spatial ecology and sex ecology. Chapter two and three respectively provides the ways how to build the pair approximation and moment methods to analytically investigate the spatially structured population. Chapter four focus on the dynamics, spatial distribution and sex ratio of spatially structured sexual reproduction population, exploring the effects of habitat decay and habitat connectivity used by pair approximation. In chapter five we construct the moment model for population including sexual reproduction and asexual reproduction, and study the condition of coexistence for these two reproduction patterns.
文章主体将分为五部分：第一章介绍了空间生态学和性生态学的概念、理论、模型和应用；第二、三章介绍了偶对近似和矩模型的构造方法；第四章利用偶对近似研究了空间局部作用和生境退化对有性生殖种群和性比率的影响；最后建立了有性生殖和无性生殖种群的空间矩方程，给出了有性种群维持和续存的空间生态条件。

The model of programmed crystallization of SPM was proposed based on the moment transformation of the population considering the agglomeration. The optimal temperature-time curves in a batch crystallizer which maximized the terminal mean size and mean weight size can be determined from the application of the Pontryagin Maximum Principle. The calculated crystallization results heating under optimal temperature were compared with ones under linear or natural heating temperature.

Both N_2 and O_2 molecules are better aligned at lower temperature, while they are poorly aligned at higher temperature. The behavior can be attributed to the population of the angular moment in the rotational wave packets of molecules at different temperatures.
理论计算表明，当分子与一飞秒激光脉冲作用后，分子在无场情况下由于转动波包的周期性恢复，N_2分子和O_2分子会出现周期性的取向现象，并且取向程度的好坏与温度有密切关系，分子取向参数的最大值随着温度的增加很快的减小，在低温减小很快，随着温度的升高这种减小趋向于缓慢；我们通过分子转动态的热分布给予了解释。
