The first writer of this paper designs the two-side electronic extensometer, which also has two edges but it can be fastened on two symmetric sides of the tensile specimen.

设计的双侧电子引伸计，只用两个刀刃而能测得试样的对称双侧变形的平均值，这样便扣除了弯曲变形的影响而得到了纯粹拉伸伸长。

The results of measurement of such electronic extensometer are instable and then more errors may be included. The first writer of this paper designs the two-side electronic extensometer, which also has two edges but it can be fastened on two symmetric sides of the tensile specimen.

最近四十年发展起来的各种电子引伸计在讯号放大及数据采集和处理方面有非常突出的优点，但大多数电子引伸计如单侧电子引伸计(图1)、光栅引伸计和视频引伸计都是测量拉伸试样单侧的变形[3]，笔者称它们为单侧电子引伸计。

In his article entitled "On the manufacture of diffraction gratings and theoretical," the paper wrote,"If every inch with the same number of two engraved lines in contact with photographic copies of the state, the two grating The engraved lines are almost parallel will result in a set of parallel stripes, the direction of the two grating carved exterior angle between the line bisection, and their distance decreases with increasing inclination."

他在一篇题为"关于衍射光栅的制造和理论"的论文中写到"如果把每英寸具有同样数目的刻线的两个照相复制品处于接触状态，使两个光栅中的刻线几乎平行则就会产生一组平行的条纹，其方向将两个光栅刻线之间的外角二等分，而其距离随着倾角的减小而增大"。

In the midst of the activity, whatever it may be, people fall into step - sometimes two men or two women, sometimes two couples, sometimes three people - and find that they walk or play a game or tell stories or serve on a tiresome and exacting committee with the same easy anticipation of what each will do day by day or in some critical situation.

在活动中间，无论是哪种活动，他们开始步调一致---有时侯是两个男人或两个女人，有时是两对夫妇，有时是三个人。他们发现在一起走路、玩游戏、讲故事或为一个令人厌烦的苛求的委员会做事等过程中，都很容易猜想对方一天天在做什么或在某个危机环境中会怎样做。

In the midst of the activity, whatever it may be, people fall into step——sometimes two men or two women, sometimes two couples, sometimes three people——and find that they walk or play a game or tell stories or serve on a committee with the same easy anticipation of what each will do day by day or in some critical situation.

在活动中，人们开始步调一致（有时是两个男人，有时是两个女人，有时是两对夫妇，有时是三个人），他们发现，无论是走路、做游戏、讲故事或是在同一居委会任职，他们都觉得能很自然地估计出每个人平时如何行事，在紧急情况下如何反应。

Accordingly,two rules for intent reduction are proposed.If a concept node has only one father concept node,then the intent reduction is formed by the difference sets of its attributes set and its father's attribute set.If a concept has several father concepts,then the intent reduction is formed by two attributes inherited from any two different fathers.

相应地提出了两条内涵缩减的规则：如果一个节点只有一个父节点，那么其内涵缩减来源于它的内涵与父节点内涵的差集；如果一个节点有两个或两个以上的父节点，那么其内涵缩减来源于任意两个父亲节点属性的并集。

The effects of different sowing dates for two varieties of field pea have been examined through field site observations in an arid area of the Loess Plateau over two years. The experiment focused on two varieties of field pea, Green pea, which has high yield, and Yannong 2, which has low yield.

通过定位试验，探讨了黄土高原旱地不同播种期对豌豆产量的影响，供试材料为绿豌豆和燕农2号。

Based on the prior information obtained by qualitative inversion, the two stages inversion method was put forward. That is, the first stage is that distinguishing the high-quality element and non- high-quality element, and determining the initial iteration value of element sound velocity reasonably. The second stage is that treating differentially the constraint weights of the high-quality element and non- high-quality element, and then quantitatively inversing the final sound velocity distribution. The results of two concrete specimens indicate that the two stages inversion method can inhibit artifacts effectively and has better defect identification effect than normal one stage inversion.

在获取定性反演先验信息的基础上，提出了两阶段反演的方法：第一阶段，区分优质像元和非优质像元，合理确定像元声速的迭代初值；第二阶段，区别对待优质像元和非优质像元的约束权重，定量反演最终的速度分布。2个混凝土试件的模型试验表明，两阶段反演能有效抑制伪像，具有比常规的一阶段反演更好的缺陷识别效果。

In order to compute the failure probability of structural systems for stability of gravity retaining walls, firstly, two performance functions against overturning and sliding of gravity retaining walls were established. Then, the first order second moment theory in structural reliability analysis, i.e., the checking point method was introduced to compute the two failure modes respectively, and two corresponding reliability indexes could be obtained.

为了计算重力式挡土墙稳定性的结构体系失效概率，首先分别建立重力式挡土墙结构抗倾覆稳定性和抗滑移稳定性的功能函数，然后引入结构可靠度分析一次二阶矩法中的验算点法分别对两种失效模式进行计算，得出两个相应的可靠度指标。

And the two doors were of fir tree: the two leaves of the one door were folding, and the two
