According to the model, the deflection and main pre-brace parameters are illustrated with the Jinsong station of the tenth line in Beijing. It demonstrates that the curve shape of theoretical result, computing result and the on-set measure result are uniform in the main and the change law is similar; that the circumferential space of pipe-roof has a optimum value while satisfying the pre-brace function; that the relation between diameter of steel pipe and flexibility of barrel vault meets negative exponential function. And the diameter of steel pipe has a optimum value.

依据该模型，以北京地铁10号线劲松车站管棚支护为例，着重对管棚的挠度和主要支护参数进行的分析表明：理论结果与计算结果和现场量测结果的曲线形状基本相同，变化规律相似；在满足预支护作用的同时，存在相对较优的管棚环向间距；钢管直径与管棚挠度之间符合负指数函数关系，管径存在最佳值。

The effects of pre-existing macrostructures, such as joint, bedding plane on AE occurrence rate and b-value are the same as that of microcracks. AE spatial distribution is controlled by the pre-existing macrostructures and the macrostructure clustered by AE events usually controls the coming final fracture.

宏观结构的存在对声发射率和b值的影响与微裂纹相同，而且宏观结构对声发射的空间分布具有控制作用，声发射丛集的宏观构造通常控制著未来的主破裂。

Epidermal cells near the wound dedifferentiate and proliferate forming blastema and/or migrate to the wound plane forming a pre-epidermis consisting of several layers of stem cells covering the wound plane, which then re-differentiates further forming fully developed epidermis. Cells in the parietal peritoneum are also induced by injury to dedifferentiate into stem cells which then proliferate and migrate along the parietal peritoneum to the wound place forming a pre-peritoneum which re-differentiates into fully developed parietal peritoneum.

伤口愈合包括伤口闭合、顶端表皮层及体腔上皮的新生：创伤后的前4 d，残腕顶端的肌肉组织向伤口处迁移并重排使伤口闭合；创伤附近的表皮层细胞发生脱分化并增殖后迁移到创伤面形成由数层干细胞组成的前表皮层，之后进一步分化形成表皮层；而体腔上皮细胞在创伤诱导下也脱分化并增殖，然后沿体腔上皮迁移到创伤处形成"前体腔上皮"，经再分化形成新的体腔上皮。

In the process of pulverized coal injection into blast furnace, the blowpipe plays an important role in pre mixing the pulverized coal and oxygen, pre heating them and improving the pulverized coal pyrolization and combustion of the coal.

在高炉富氧喷煤过程中，直吹管使喷入的煤粉与氧气预混、预热，并促使煤粉的热解和部分煤的燃烧。

But because I am concerned here only with poems in the vernacular, and am not discussing those in the regulated language, I say that there is one form of vernacular poetry that excels all others, and that, on account of its pre-eminence, we call the canzone; and that the canzone is pre-eminent was proved in the third chapter of this book.

但因为我这里只涉及用方言写的诗歌，而不管用规范语言写的，我认为有一种方言诗歌形式鹤立鸡群，考虑到它的优越性，我们称之为歌曲；歌曲的优越将在本书第三章给出证明。

The main features of the protocol are:1A series of different classes of emergency critical care plans were pre-designed,each class of plans would be triggered by a MEWS score pre-established;2The content of each class included on the frequency of monitoring patients\' vital signs,a MEWS score can be obtained by vital signs,if the MEWS score reached a trigger value,the corresponding class of plans would be launched immediately.3 When a patient was admitted into emergency department,various classes of plans would be launched automatically one after the other according to MEWS,resulting in the procedural critical care process.

该监护方案的主要内容为：1预先设计的多种级别急诊监护预案，各级预案由预先规定的MEWS分值触发；2每级预案中均规定监测生命体征的频率，通过生命体征参数获得MEWS评分，如MEWS分值达到另一级预案的触发值，相应预案立即启动。3从第一次MEWS评分开始，各级预案根据MEWS分值的变化自动的相继触发，产生程序化的监护流程。

By using damping force between steel and columniation after pre-deformation, adjusting the type, quantity, length and position of the steel bar, and changing pre-deforrnation of the steel bars, all kinds of deceleration curves can be repeated.

介绍了自行设计的汽车模拟碰撞吸能器的特点及原理，利用LS—DYNA有限元分析软件对吸能器的波形复现原理进行了仿真分析，利用销柱间钢筋预变形产生阻尼力，改变钢筋的属性并调节钢筋的类型、数量、长度和位置，改变钢筋预变形量，复现出不同车重、不同碰撞车速所期望的减速度波形。
