使后屈

She'll be competing with a heart-stopping backward 3.5 somersault pike—and hoping that the third time is the charm.

这次奥运会她将使出令人心惊肉跳的一招：向后翻腾三周半转体一周屈体（backward 3.5 somersault pike）。

Although the clinical experience and the results of animal experiments indicate that the adminis- tration of atracurium at recommended doese is unlikely to result in laudanosine concentrations capable of producing seizure activity, Hennis et al found that at a plasma concentration below that causing convulsions, laudanosine "awaken"dogs lightly anesthetized with halothane.

临床病人应用常用剂量阿屈宁后，血浆Laudanosine选低于使动物发生惊厥所需的浓度，数百万例应用阿屈宁的病人中也未见有因代谢生成之Laudanosine而发生惊厥体征或脑电征象者。可以认为，阿屈宁的临床应用是不会因Laudanosine的生成而引起惊厥的。

Midwifery were quickly placed palace at the bottom with one hand, thumb in the anterior, posterior wall of the remaining four means for Palace at the end of even a massage by massage the uterus starts to contract, can be placed in the vagina before the one hand fist fornix, to withstand the uterus anterior abdominal wall push the other hand since the back wall of the uterus, so that the uterus flexion, the relative pressed his hands to massage the uterus.

助产者迅速用一手置于宫底部，拇指在前壁，其余4指在后壁，作均匀有按摩宫底，经按摩后子宫开始收缩，亦可一手握拳置于阴道前穹窿，顶住子宫前壁，另一手自腹壁按压子宫后壁，使子宫体前屈，两手相对紧压子宫并作按摩。

The research results showed that (1) inelastic compressive behavior of the gusset plate was similar to a cantilever plate in compression load,(2) buckling strength was reasonably predicted based on an inelastic plate buckling equation and buckling coefficient, and (3) design guidelines of the gusset plate in compression were proposed with inclusions of edge stiffeners.

本研究结果显示：(1)含挫屈束制消能斜撑之接合板在受轴压作用下，将产生的挫屈模式为Fixed-Free、(2)接合板在Fixed-Free模式下之挫屈强度预测及(3)如何加劲接合板使其强度能达到降伏后之非弹性挫屈行为。

After knee joint replacement, the artificial joint should bear the weight of the body, furthermore, when it is flexing or whirling, it must be flexible and have a good stability. To make a coordinated movement between the joint prosthesis and the retained soft tissue, the geometry of joint prosthesis must match human body.

膝关节置换后，要求患肢达到负重、伸屈及旋转活动，稳定性好，这就要求假体的几何形状要与人体相匹配并使其植入后与人体运动规律相一致，才能使假体与周围保留的软组织协调运动，这一切都得依赖于精确的膝关节假体设计与制造。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.

采用不同浓度K2CrO4(0，0.4，0.8和1.2 mmol/L)的Hoagland营养液处理黑麦幼苗，测定铬在黑麦体内的亚细胞分布、铬化学形态及不同部位的积累。

By analyzing theory foundation of mathematical morphology in the digital image processing, researching morphology arithmetic of the binary Image, discussing two basic forms for the least structure element: dilation and erosion.

通过分析数学形态学在图像中的理论基础，研究二值图像的形态分析算法，探讨最小结构元素的两种基本形态：膨胀和腐蚀；分析了数学形态学复杂算法的基本原理，把数学形态学的部分并行处理理念引入到家实际应用中。
