闭合-断开

According to generalized modular design, finite element models of each function module are built in ANSYS, which belong to pre-tightening frame of 45 MN forging press. MPC banded contact is used to simulate the connection of two fixed parts, while standard contact is used to simulate the connection of two dissociable parts, Deformations and stresses of the forging press under two working conditions are discussed, which provide good guides to the design of such kind of press.

依据广义模块化设计原理，在ANSYS中分别建立了45MN锻压机预紧组合机架各个功能模块的有限元模型，采用MPC绑定接触模拟闭合模块间的连接，标准接触模拟可开裂模块间的连接，分别讨论了空载和临界载荷两种状态下机架的变形和应力分布，计算方法和计算结果为此类机架的分析、设计提供参考和指导。

The device, small in size, can be installed in the drivers' cab, which hasn't any side effect on driving. During the drive, the device captures the real-time parameter of driver' blinking frequency as well as the parameter of driving duration. Then the PERCLOS value is calculated to judge whether a driver is drowsing off or not.

该装置体积小，可安装在驾驶室内驾驶台上，完全不影响驾驶员正常的驾驶活动，行车过程中实时获取驾驶员的眨眼频率和眼睛持续闭合时间等与疲劳相关数据，计算 PERCLOS 值判断驾驶员是否打瞌睡。

By the theory of complex functions, dynamic propagahon problem on Dugdale model of mode Ⅲ interface crack for nonlinear characters of materials was studied. The general expressions of analytical solutions are obtained by the methods of serf-similar functions. The problems dealt with can be easily transformed into Riemann-Hilbert problems and their closed solutions are attained rather simple by this approach.

通过复变函数论的方法，对材料的非线性特性下的Ⅲ型界面裂纹Dugdale模型的动态扩展问题进行了研究，采用自相似函数的方法可以获得解析解的一般表达式，应用该法还可以很容易将所讨论的问题转化为Riemann-Hilbert问题，并可以相当简单地得到问题的闭合解，利用这些解并采用叠加原理，就可以求得任意复杂问题的解。

Help your baby's early closure microcephaly or brain dysgenesis.

General in the 12-18 months when closed, not too early or too late, and will affect intelligence.

一般在12-18个月的时候闭合，太早或太晚都不好，会影响智力的。

Both switching points have electrodynamic drives which open and close very quickly.

两个开关点都具有可以非常快地打开和闭合的电动驱动器。

The infinite elliptic cone geometry can be transformed into the two-dimensional plane under the assumption of pure TEM spherical waves. The closed-form solutions for the characteristic parameters are obtained.

应用坐标变换和共形变换研究椭圆双锥天线，在传输纯TEM波的假设下，把无限长椭圆双锥结构变换为二维平面结构，从而得到椭圆双锥天线输入阻抗闭合解，其典型结果与文献一致。

Dretske thus concludes that we should instead allow that an agent might be able to know while failing to know, and thus, given that the entailment is known, that closure fails.13

Dretske 于是结论说，我们应该允许一个人能够知道但不知道，于是，假定蕴涵是被知道的，那么闭合原则就是假的。

RESULTS: After 34 weeks, patients occured varying degrees of swelling of the eyelids. Incomplete eyelid closure dribbled away. Followed up for 418 months,doubleeyelids of patients were basic symmetry; the arcs were smooth; ptosis was corrected; depression of the upper orbital region was improved obviously; and no complications appeared, such as entropion and ectropion of the eyelid and eyelid deformity.Only 1 eye was rectified insufficiently.

结果：术后3～4wk内患者均有不同程度眼睑肿胀，眼睑闭合不全逐渐消失，随访4～18mo，患者双眼睑重睑基本对称，弧度流畅，上睑下垂矫正，上眶区凹陷明显改善，未出现眼睑内外翻及眼睑畸形等并发症，有1眼欠矫。

On the base of the acoustics , a whole linear time - varying discrete speech produce model is established through anatomising the factors including track , driving source and lip eradiation the mechanism of speech in this paper , and we draw a conclusion that the time between glottal closure is pitch period

本文从声学理论出发，剖析了语音产生的机理，综合考虑声道、激励源和嘴唇辐射三方面的因素，建立了一个完整的、线性的和时变的语音产生的离散系统模型，得出两次声门闭合事件之间的时间间隔就是基音周期的结论。
