When the temperature is above 100℃, no reaction of SiO_2 with gaseous hydrogen fluoride is observed, but the reaction is accelerated when the surface of SiO_2 is coated by a special polymer film.

二氧化硅与气相氟化氢的反应和与氢氟酸的反应不同，当温度高于100℃时，气相氟化氢与裸露的二氧化硅无明显反应，当二氧化硅表面涂上一层特殊聚合物膜时，反应可很快发生。

Given these factors, some areas have become a treasury wellof well-preserved ichthyosaur ichthyosaur fossils.

当这些因素存在时，当这些因素存在时，某些地区就会变成一个充满保存完好的鱼龙化石的宝库。

When the actuated joint was rotary actuation, kinematic Jacobian matrix of the manipulator was a diagonal matrix. So it was an uncoupled mechanism. As the actuated joint was linear one, Jacobian matrix of the manipulator was an identity 3×3 matrix and its determinant was equal to one. Manipulator, therefore, was singularity-free fully-isotropic throughout the entire workspace.

当以转动输入为主驱动时，运动雅可比矩阵为3×3阶对角阵，故机构为无耦合并联机构；当以移动为主驱动时，雅可比矩阵为3×3阶单位阵，且其行列式的值为1，所以在整个工作空间内机构表现为无奇异完全各向同性。

Secondly, a conjecture about the stability for these systems is proposed based on the sufficient and necessary condition of the isolated transfer function being positive real. When the zeros and poles of the transfer functions lie in the imaginary axis, a known conclusion is derived from the conjecture; while the zeros and poles are on the real axis, a new result is obtained and is proved in this note. Finally, according to the conjecture, an example with poles existing on the complex plane is presented, which is not only interesting but also challenging.

然后， 基于所有孤立部分传递函数都正实的充分必要条件给出了上述系统为稳定的一个猜想，当传递函数的零极点都位于虚轴上时，由这一猜想得到了一个已知的结论；当传递函数的零极点都位于实轴上时，由这一猜想得到了一个新的结论，本文证明该结论是正确的；最后，根据这一猜想，给出了传递函数极点位于复平面的一个例子，它涉及到一类系数矩阵为时变正定矩阵的振动方程的稳定性问题，值得去深入研究。

The main theorem of this paper is to, firstly, on the grounds of experience preliminarily estimate the parameter of the pavement nonlinear model, simulate the process with computer procedure, and check the result with the data collected in sit, then set the aim function and the superiority back-calculation method, if the function is not satisfied, it is to the method adjust the parameter and make the model impend the actuality, If the function is satisfied, it is to end the process, and record the stress, deformation, displacement and the parameter as the actual condition.

本文分析的主要原理：首先根据经验，初估路面结构层应力应变非线性参数，利用计算机程序模拟承载板试验测回弹弯沉的过程，通过现场实测的弯沉数据来检核该模拟过程的真实性，设定目标函数，选定适当的优化反算方法，当目标函数不满足时，即利用该优化反算方法调整本构模型参数，使得模型能够逐步向真实解逼近，当目标函数得到满足时，则认为此时反算得到的路面结构层的应力、应变、位移场为真实的应力、应变、位移场，所推算得到的非线性应力应变模型为真实的路面结构层应力应变模型。

Truly understand the meaning of impermanence, when you pain, you want to this pain is not eternal, and when you are happy, you want to that happiness is not eternal.

真正了解无常的含义，当你痛苦时，你要想这痛苦不是永恒的，当你快乐时，你要想这快乐也不是永恒的。

From the almost prehistoric uprisings of savage tribes against chieftains of Asiatic empires, the negative to submission, the protest against the tyrant, the no of the oppressed has been the word, the genesis of the emancipation of peoples: and even when the impotency of the means and the efficacy of the goals, as in our homeland, separate the revolutionary fire from the vision of the ideal, the no must be and is the only saving word of the freedom and dignity of enslaved people.

自史前原始部落反抗亚洲帝国首领的统治开始，在不愿屈从，反抗暴君的斗争中，"不"就一直是被压迫者所使用的词。它是使人民获得解放的开端。即使像我们国家这样，当我们的力量太弱，不足以有效地实现我们的理想时，当我们的革命力量与远大理想之间差距太大时，"不"，肯定是，而且也是唯一的可以拯救被奴役的人们的自由与尊严的词。

With the increase of MnO2 mixture, the iron content in clinker will be increased while C 3A and C 3S contents decreased, and the incipience of liquid phase will have higher temperature.

当MnO2掺量小于20％，煅烧温度高于1400℃时，MnO2对生料的易烧性影响不大；当煅烧温度低于1400℃时，MnO2使得生料的易烧性变差。

When you see his hands unfold with the big exchange extent movement in vertical direction, you can hear aroused melody, and you would feel infuriation momentum. While when you view his hands spread out with a certain radian, the band will send you a melodious rhythm, and then you will feel relaxed......

当你看到他的手展开，在垂直方向做大幅度的运动时，乐队奏出的就是激昂的旋律，你会感受到一种万马奔腾的气势；而当你看到他的手舒展开来，做一定的弧度摆动时，乐队则会为你奉上悠扬柔和的曲调，你也会放松下来。。。。。。

Generally speaking, however, the number of discrete signals in animal repertoires seems to be limited (Green and Marler 1979; Moynihan 1970), although reliable repertoire estimates are hard to come by, especially when signals intergrade extensively. Explosive expansion of the repertoire becomes possible if elements of the repertoire can be recombined into new, meaningful utterances, as they are in human speech.

但是，总的来说，在动物的曲目当中，不相关的信号是有限的（格林和马勒1979；莫伊尼汉1970年），尽管可靠的统计难以获取，尤其当信号过渡段很广时，当剧目中的元素可以被重组为新的，有意义的话时，剧目的爆炸性扩张成为可能，就像是在人类语言中一样。
