PAL activity, chitinase activity, total Polyphenol content and total Flavonoids content in soybean leaves induced by the same crude toxin and race were similar, it stated that the crude toxin is an important factor which can induce resistant substances, but the induced speed and the induced intensity by the crude toxin and conidium were different. Firstly, the induced speed of crude toxin which induced PAL activity and total Flavonoids content of resistant soybean varieties was faster than speed of C.

同一生理小种的粗毒素与灰斑病菌对大豆叶片内PAL活性、总多酚类含量、总黄酮含量以及几丁质酶活性等几种生化指标均表现出相似的诱导作用，由此可推断粗毒素是诱导大豆叶片内的PAL活性、总多酚含量、总黄酮含量以及几丁质酶活性产生变化的主要生物因子，只是二者在对抗性不同的大豆品种的诱导速度及强度上存在一定的差异。

First by introducing the sufficient decrease condition,the Wolfe condition and the Goldstein condition with their strong local search capabilities, do the step length selection. The search direction is using conjugate gradient direction.

通过引入经典优化中局部搜索能力较强的充分下降条件、Wolfe条件、Goldstein条件确定步长，而搜索方向采用共轭梯度方向进行局部搜索，由此得到一类高效的非精确的混合遗传算法。

The conjugational and delocalizational energy levels were calculated by Gaussian 98, and its hypsochromic shift mechanism was also discussed.

用Gaussian 98计算了共轭p键和离域键能，由此讨论了吸收波长发生蓝移的机理。

In the grease is added to ceramic type particles,"this will be the base oil components are connected together as like a chain, so that the performance of grease stronger."

在润滑脂中添加的是陶瓷类微粒，"由此将基油中的成分像链条一样地连接起来，从而使润滑脂的性能更强"。

Hence they attempt to create a "scientific" connoisseurship method established upon a kind of solid, reliable and interpretable basis, and are determined to point out that art connoisseurship is not depended on intuition or general impression, and has no mystery.

由此，他们试图建立起一种坚实可靠的而又可以诠释明白的"科学"的鉴定方法，决意表明艺术鉴定活动并非依靠直觉或总印象，也无任何神秘性可言。

It could also avoid oversupply and the consequent economic problems.

这也能避免供应过剩和由此引起的经济问题。

That's the only way that my work can stay true and consequent to what it serves and to connect itself with others.

这是唯一的办法，我的工作可以保持真正的和由此产生的什么服务，并与其他人联系本身。

In no event shall the seller be liable for indirect or consequential damage .

卖方不承担间接原因发生的损失，或由此而造成的损失。

The effects of the structure constant of the refractive index fluctuations Cn2 and the inner scale of the turbulence l0 on the M2 factor have been analyzed quantitatively. Consequently, a new method for determining the characteristics parameters of the turbulence based on the measurement of the M2 factor by experiments has been proposed.

定量分析了表征大气湍流参数的折射率结构常数Cn2和涡旋内尺度l0对M2因子的影响，并由此提出了一种通过实验测量大气湍流中光束的M2因子，进而确定出大气湍流参数的新方法。

Based on the equilibrium equation of an arch element the cubic nonlinear dynamic model with second order is established and the nonlinear differential dynamic system without constant term is obtained through a transfer process of T=U+b. Hence three fixed points and the homoclinic orbits are found. The critical condition of the chaotic vibration of the elastic arch is given by using the method of Melnikov function. The numerical results of the stationary and chaotic motion are given and discussed.

首先利用拱的单元平衡方程建立了拱的二阶三次非线性动力学模型；然后通过变换使方程转化为不含常数项的非线性微分动力系统，并由此得到无扰动系统的3个不动点与同宿轨道；再用Melnikov函数法给出了发生混沌的临界条件；最后给出了该系统出现定常运动和混沌运动的数值结果。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
