根的

The method that simple cubic equation was changed from general to standard was introduced and the distribution of standardized real root was illustrated, which solved the problem of the distribution of any real root for simple cubic equation.

摘要介绍了一元三次方程一般式化为标准式的方法，结合图形给出了标准式的实数根的分布情况，从而解决了任意一元三次方程的实数根的分布的问题。

In this paper, a new method used to deal with the motion ability is studied deeply based on Routh-Hurwitz Criterion. The advantage of this kind of analysis method consists in the fact that after establishing the equation in differential calculus for the motion system, there is no need to know a root of the equation, if you know the root signs, you can judge the zero solution stability of the system.

本文利用劳斯－赫尔维茨判据(Routh-Hurwitz Criterion)对机械系统中离心转速调节器的运动德定性进行了分析，这种分析方法的优点就在于：建立系统运动微分方程的特征方程后，不必求解特征方程的根，只需知道根的符号就可判断系统的零解稳定性。

Bacon's phrase was based on a sense of the Latin word crux,"cross," which had come to mean "a guidepost that gives directions at a place where one road becomes two," and hence was suitable for Bacon's metaphor.

培根的这一词组是基于拉丁语crux "十字形"的意思之上的，它的意思为"在一条路分为两条岔路的地方用于指示方向的路标"，因此它适用于培根的这一比喻。

At the same time, the limitations in researches are also argued. In the last part, the philosophical and scientific standpoints of Bacon\'s Novum Organum are evaluated. And, it is concluded that Bacon succeeds and criticized predecessors. Moreover, his thoughts influenced the modes of thinking of later generations.

所以本文在这一部分中深入探讨了培根的基本科学研究、具体科学见解和在科学研究中存在的局限性；最后，本文欲对《新工具》中的哲学和科学思想进行评论，较深入地梳理培根对前人的继承和批判、对后世的影响和对今天的启示。

The result also show that:mycorrhiza' s promotion to Populus ussuriensis seedlings ' growth is directly related to the improve ment of inoculated seedlings' chlorophyll content and enzyme activity.

结果还表明，菌根的促生长效应与菌根化苗木的叶绿素含量的增加及过氧化氢酶活性的提高呈正相关。

This has nothing to do with Bacon as the phenomenon of last year's hot auction market, now extinguished, where one of his triptychs sold for $86 million.

这和培根做为去年的拍卖市场的热点无关，在那里，培根的三幅相连图画之一卖出了八千六百万美元的价格。

The recent studies showed that most orchid mycorrhizae belong to Basidiomycota and Deuteromycotina fungi, and some belong to Ascomycota. There are two modes for the formation of orchid mycorrhizae, one is the infection of orchid seeds and the other is the infection of orchid radicles.

目前研究已知，感染兰科植物根部并能与之共生的真菌绝大多数属于担子菌门和半知菌门，也有部分属于子囊菌门；兰科菌根的形成可分为两种情况：一是对兰科植物种子的侵染；二是对成长新根的侵染。

This paper studied branching characteristics of the young maize radicels with growth ages 9 and 19 days using potted experiment in greenhouse under the condition of no stresses of water and nutrients based on simplified hidden-semi Markov model.

摘要控制玉米植株生长在不受水分，养分胁迫的条件下，采用室内盆栽实验方法，以播种后生长了9天和19天的玉米(农大108)胚根为研究对象，基于简化的隐式半马尔科夫模型，分析了玉米胚根的分支特性。

Peter's Square, one of the largest squares in the world, as the architecture masterpiece of Benigni. From 1656 to 1667, Benigni used 248 columns and 88 pilasters to make this grand elliptic square. In this square, there is the St.

绝不可错过的有圣比得广场，世界上最大的广场之一，贝尼尼的建筑杰作，他在1656至1667年间用284根和88根的双排柱围成了宏大的椭圆形广场。

Lonergan's understanding of the human person is built on two pillars of this thought: his basic epistemological stance that the real is verified intelligibility and his understanding of world process as emergent probability.

本文將描述郎尼根的人学；本文认为郎尼根对人性位格的瞭解乃是立基於此思想中的两大支柱，即：其知识论凭本立场为，真实乃是可验证的可理解性；而其对世界歷程的瞭解则为突现机率。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
