The stochastic Bonhoeffer-Van der Pol system is first transformed into an equivalent deterministic system using the Chebyshev polynomial approximation, so that the problem of controlling stochastic chaos is reduced to the problem of controlling deterministic chaos in the equivalent system.

首先运用Chebyshev多项式逼近的方法，将随机Bonhoeffer-Van der Pol系统转化为等价的确定性系统，使原系统的随机混沌控制问题转换为等价的确定性系统的确定性混沌控制问题，继而可用Lyapunov指数指标来研究等价确定性系统的确定性混沌现象和控制问题。数值结果表明，随机Bonhoeffer-Van der Pol系统的随机混沌现象与相应的确定性Bonhoeffer-Van der Pol系统极为相似。

It is proved that the two-dimensional non-hydrostatic Boussinesq equations on the x ? z plane with the kinetic viscous term and the thermal dissipative term are unstable equations in the C 2 function class.2. If we replace the influence of the kinetic viscous term by Rayleigh friction and the thermal dissipative term by Newton cooling, the new generalized equations are stable equations in the C 1 function class. The construction of the solution space and the discriminating method for well-posedness of the problem of determining solution are given.

The investment of IT is propelled mainly by IT engineers, so they mainly rest on technique, barely rest on economic. Even they rested on economic, system analysis are limited in qualitative and recapitulative and dispersive targets and did not formulate a set of systematic and integrated target system as reference or evaluation basis.

由于IT项目的投资实施主要是由主导信息技术的IT专业人员推动的，因此以往的研究往往把主要精力放在技术评价和实施上，但对其经济评价的探讨有所忽略，即使进行这方面的分析，大多也停留在几个定性的、概括性的、分散的指标上，并没有形成一套系统的、完整的指标体系和相应有效的评价方法。

COMPAREED WITH THE POETIC EXPERIENCES AND PHENOMENA WHASE NATURE HAS BEEN DETERMINED DURING THE LITERARY HISTORY, THE'THIRD GENERATION'POEMS, NOW STILL AFTER THE AGITATION, AND TRYING FOR CERTAIN FIRM TRANSFERENCE, ARE RATHER LIMITED IN DEALING WITH HISTORY AND THEORETICAL SIGNIFICANCE, WHETHER ON TIME SPAN OR SPIRITUAL LEVELS. THIS PAPER, THEREFORE, LAYS EMPHASIS ON DESCRIPTION AND INTERPRETATION AS WELL AS PRUDENT VALUE JUDGEMENT, INSTEND OF ARBITRARY DECISION.

与那些业已具备了历史定性的诗歌经验和现象相比，激荡之后归于沉潜，如今正在作出某些内坚实在的推移的&第三代&诗，无论在时间跨度上还是在所展示的精神层面上，对历史和理论意义的容纳程度都还显得相对有限，由此规定了论文对描述和阐释的侧重，以及对下论断式的价值判断尽可能保持谨慎的态度，后者将有待于&第三代&更为充分、完整的发展和立足于其上的更为充分的研究后，再加以弥补。

Men, at first, for the most part, contented themselves with what unassisted nature offered to their necessities: and though afterwards, in some parts of the world,(where the increase of people and stock, with the use of money, had made land scarce, and so of some value) the several communities settled the bounds of their distinct territories, and by laws within themselves regulated the properties of the private men of their society, and so, by compact and agreement, settled the property which labour and industry began; and the leagues that have been made between several states and kingdoms, either expressly or tacitly disowning all claim and right to the land in the others possession, have, by common consent, given up their pretences to their natural common right, which originally they had to those countries, and so have, by positive agreement, settled a property amongst themselves, in distinct parts and parcels of the earth; yet there are still great tracts of ground to be found, which (the inhabitants thereof not having joined with the rest of mankind, in the consent of the use of their common money) lie waste, and are more than the people who dwell on it do, or can make use of, and so still lie in common; tho' this can scarce happen amongst that part of mankind that have consented to the use of money.

最初，就绝大部分人而言，满足于自然直接提供给他们的生活必需品；然而后来，世界某些部分的种群，（在那里，人口和储蓄的增长，并随着货币的使用，使土地变得不足，因而有了一些价值）多个社群之间确定了他们各自的领土边界，并在社群内部通过法律管理他们社会的私人财产权，于是通过契约和协议，确定由劳动创造的财产权；多个国家和王国之间则订立盟约，以明确表达或默认的形式否认了彼此之间的土地要求和权利，从而，基于共同的同意，放弃了他们原初对于别的国家所拥有的自然的共有权利的要求，于是，通过肯定性的协议，确定他们之间的财产权，在地球上形成各个不同的国家；然而还有大片土地被发现，（那里的居民并未与其余的人类通过使用共同的货币而融合在一起）这些土地处于荒芜状态，多于那里的居民所能够使用，因而仍处于共有状态；不过这种情形很少发生在那些同意使用货币的人群之中。

The split between the two groups can hardly be papered over.

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
