一次

I have had two life-after-life experiences: one in a flotation tank , one after a motorcycle accident.

我有两次经历生死之间的经验。一次是在浮水箱里，还有一次是摩托车事故。

Methods: Silicone rod frontalis sling had been performed in blepharoptosis (23 cases, 27 eyes) from January 2002 to January 2004 at the Department of Ophthalmology, Tri-Service General Hospital, National Defense Medical Center. We retrospectively studied the primary result of all patients.Result: With a mean follow-up of 11.8 months, a good final result was achieved in all eyes, with no recurrent ptosis cases.

我们追踪自2002-2004年间使用silicone rod frontalis slings的病患，23位病人，27个眼睛，其中两位是外伤导致单侧third nerve palsy，一位是单侧Marcus Gunn jaw-winking syndrome，一位是单侧眼瞼下垂已接受三次传统矫正手术，一位是单侧眼瞼下垂已接受一次传统矫正手术，一位单侧先天性眼瞼下垂的小朋友，一位双侧先天性眼瞼下垂的小朋友，其他19个眼睛均是先天性眼瞼下垂的成人(table 1)。

The scale of glaciers in the Tanggula Range has become smaller and smaller since the penultimate glacial epoch because of the drying process and severe shortages of moisture in the interior of the plateau due to the uplift of the plateau.

由於青藏高原的隆升，对高原腹地引起的干旱化过程和水分严重不足，使唐古拉山地区的冰川自倒数第二次冰期以来，冰川规模一次比一次明显地减小。

Graf: It isn't easy. We've already gone through these moments a fewtimes, and they will happen again and again.

小格：那并不容易，我们已经经历过很多次这样的时刻，这些不幸一次又一次的发生。

Henry Kissinger had slept here before, in July and again in October.

以前海瑞基辛格曾两次在这里下榻，一次是在七月，另一次是在十月。

In ideal conditions, a pump, the second pump and the lift of a pump system pumps the same lift.

在理想工况下，一次泵、二次泵的扬程之和与一次泵系统水泵扬程相等。

The late Mr. Drabdump had scratched the base of his thumb with a rusty nail, and Mrs. Drabdump's foreboding that he would die of lockjaw had not prevented her wrestling day and night with the shadow of Death, as she had wrestled with it vainly twice before, when Katie died of diphtheria and little Johnny of scarlet fever.

已故的达顿普先生大拇指根部曾被生锈的铁钉刮破，达顿普夫人预感到他将会死于破伤风，但她并没有在死神的阴影来临前日夜斗争，因为她以前已经徒劳地斗争过两次，一次是卡蒂死于白喉的时候，一次是小约翰尼死于猩红热的时候。

This model is different from the structural dynamics model in a non-inertial reference frame with large overall motions known.

本文从力学基本原理出发，分析了刚柔耦合零次近似理论失效的原因，深入研究了有大范围运动的柔性体变形场的描述，建立了刚柔耦合一次近似的动力学模型；然后利用上述模型，从非惯性系下的结构动力学问题和大范围运动为自由的刚柔耦合动力学问题这两个层次上进行了刚柔耦合动力学建模理论与性态的研究，采用理论和实验相结合的手段来检验了一次近似刚柔耦合动力学模型的正确性。

It is antinomy to analysis factor effects according to first and second order term index of quadratic polynomial,so this paper put forward a new method to explain and evaluate factor effect by F test based on partial regression sum of squares.

传统的二次多项式回归方程在依系数正负、大小解释各因子效应时，常出现一次项与二次项结果相互矛盾的情形，而一般的SVR模型又不具解释性；本文从偏回归分析定义出发，建立了基于SVR以F测验解释、评价各因子相对重要性的方法。

Based on the first heat treatment, the second ball milling and calcining favor the osculation and mass transfer of the reactants in the second solid state reaction, and compared with one-step method, the density of resultant LiFePO4/C is ameliorated.

在一次热处理的基础上，二次球磨和烧结有利于第二次固相反应过程中反应物质的接触和传质，较一步固相法提高了生成的LiFePO4的振实密度。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
