对称的

When developing the flexure formula we imposed a condition that the cross-sectional area be symmetric about an axis perpendicular to the neutral axis; furthermore, the resultant internal moment M acts along the neutral axis.

当发展我们强加了一种情况代表性的区域是对称的有关对中立的轴轴垂直线的事屈曲公式的时候；此外，合量内在的片刻 M 沿着中立的轴行动。

The flywheel has a shape formed by rotation, around the rotation axis, of a geometric figure symmetric about the rotation axis and the axis perpendicular to the rotation axis, and split into two parts (2, 3), e.g. of equal volume, by a plane passing at an angle greater that forty five degrees and smaller than ninety degrees to the rotation axis, the two parts being rotated relative to each other around the rotation axis at an angle no greater than ninety degrees.

所述飞轮具有由相对于旋转轴线和垂直于该旋转轴线的轴线对称的几何图形围绕旋转轴线旋转所形成的形状，并被与旋转轴线成大于45度小于90度角的平面分成两部分(2、3)，例如等体积的两部分，所述的两部分围绕旋转轴线以不大于90度的角度彼此相对于旋转。

How to work out the amount of the adjustment in the air blow that can resolve this position caused by rubbing against dirty, how to work the following guide roller is in walking distance to adjust to the right, in accordance with the principle of symmetry to the how to work with nose, typically a business card printing and membership card making paper thickness of 3-4 times, otherwise it will cause the jammed paper break when joint or book-fold folded edge of the left and right deviation and get dirty.

三角板内吹风量的调节可解决此部位引起的蹭脏，三角板下面的导纸辊之间的距离调节要合适，按对称的原则，以三角板鼻尖为基准，一般为制卡和会员卡制作用纸厚度的3—4倍，否则会引起接纸时接头卡住断纸或书帖折页的左右偏差与局部蹭脏。

By expanding the L-B model and integrating the impulsions into the model, we can conclude the different influeces to corporation value and debts level come from different impulsions:1 The change of demand——If the demand increases temperately, the corporation value also increases and the firm will increase its debts level, vice versa.2 The change of technology——New technology reduces products\' cost and improves the corporation value, the firm will increase debts level. 3 The unsymmetrical change of the firm\'s decision——The leader\'s corporation value increases and will increase its debts level, the follower is contrary.

对L—B模型进行扩展，将随机冲击的影响纳入模型，可以导出随机冲击对企业整体价值、负债水平产生的不同的影响：1市场需求变化——当市场需求温和上升时，企业整体价值上升，企业有增加负债的动力；温和下降时情况相反。2技术更替——技术更替降低了产品成本，提高了企业的整体价值，企业有增加负债的动力。3非对称的市场决策变化——领导企业的整体价值上升，有增加负债的动力；跟随企业则相反。

Similarly, reprises of earlier passages later in a piece not only have their melodies ornamented and varied, but also can move off on quite a different harmonic course, or with the accompaniment transformed, allowing the symmetry of ternary form to be offset by a more forward-moving dramatic shape.

同样的，在一个篇章后部对较早段落的重复不仅具有各自不同的加以修饰和改变的旋律，而且还使用不同的合音方式及伴奏配乐。这样一来，就用一种前移的生动形态弥补了三元形式对称的不足。

The metal ions of the dinuclear copper complex of [Cu_2_2Cl_4] are linked by two N~1,N~2 1,2,4-triazole bridges,and the central Cu ions have distorted trigonal bipyramid geometries. The central Cu ion of [CuL22]·H2O has a centrosymmetric and distorted tetragonal-octahedral geometry. The metal ions of the dinuclear manganese complex of [Mn_2L_2_2Cl_2(H_2O)_2] are bridged by two chlorine atoms, and the central Mn ions have distorted tetragonal-octahedral geometries. Part III.

配合物[Cu_2_2Cl_4]是通过配体L的1，2，4-三唑环上两个氮原子(N~1，N~2)桥联形成的双桥双核配合物，每个中心铜离子都具有畸变的三角双锥构型；配合物[CuL22]·H_2O的中心铜离子具有中心对称的畸变八面体构型；配合物[Mn2L2_2Cl_2(H_2O)2]是通过两个氯原子桥联形成的双桥双核配合物，每个中心锰离子都具有畸变的八面体构型。

The water chamber takes the shape of tilting cube, in favor of uniform distribution of cooling water on tube plate surface. The tube bundle is divided into two groups of zygomorphy according to the bisection system and it has eight support clapboards. The siphonopore center of each clapboard increases a certain distance corresponding to that of two tube plates and the cooling tube takes the shape of arch. The two-way cooling water of bisection flows through the condenser in opposite direction so as to improve the distribution of heat load for tube bundle. Around the throat of condenser, the final stage low-pressure heater, air extraction tube, intake device of bypass exhaust and the like are deployed.

它的特点是：水室呈倾斜立方体形状，有利于冷却水流在管板面上均匀分布；由于采用对分制，管束相应地分为左、右对称的两组，并且管束设有八块支撑隔板，每块隔板的管孔中心相对于两端管板的管孔中心依次抬高一定的距离，以使冷却管呈拱形状；对分制的两路冷却水以相反方向流过凝汽器，从而改善管束的热负荷分布；在凝汽器喉部布置了末级低压加热器，抽汽管道及旁路排汽接受装置等。

Firstly, the essential definition of Venture Capital is given, and the basic operational process of venture capital investment is synoptically introduced. Secondly, in the environment characterized by uncertainty and asymmetrical information, the risk control mechanisms in contracting are discussed in detail, and several commonly employed risk control mechanisms are emphatically analyzed.

首先给出风险投资的基本含义，概括介绍了风险投资运作的基本过程；较为详细地讨论了存在不确定性和严重信息不对称的风险投资环境下的契约设计中的风险控制措施，重点探讨了实践中最常用的几种风险控制机制；对风险投资运作过程的最后也是至关重要的环节一退出，着重进行了论述。

The number and intensity of peaks of the thermoluminescent cutves are obviously related to stages of gold mineralization:the curve of the early barren quartz shows nearly Symmetric pattern; that of the major stage auriferous quartz is of multimodal type; the curve of the late quartz, low in gold, is marked by unimodal--bimodal type with rather intense luminescence.

石英热发光曲线的发光峰的数量和强度与金成矿阶段有着明显的关系：早期成矿阶段结晶的基本不含金石英，热发光曲线常为近对称的单峰型，发光强度较大；主成矿阶段形成的含金石英，热发光曲线为多峰型，常具最大的发光强度；晚期成矿阶段生成的含金性较差的右英，热发光曲线呈单峰-双峰型，发光强度亦较大。

In the realistic tax revenue, the tax revenue gambles both sides not to be impossible, not to have the cost gain information, the information content which the information issue side and the demand side has is not assymetrical quickly, the information issue side general meeting unintentionally conceals or abbreviates some to the oneself disadvantageous information, the information demand side in gains and confirmed when these information is must spend the cost.

在现实税收中，税收博弈双方不可能快捷、无成本地获取信息，信息的发布方和需求方拥有的信息量是不对称的，信息的发布方总会有意无意地隐瞒或省略一些对自己不利的信息，信息的需求方在获取和证实这些信息时是要花费成本的。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
