时间的

But Stoic introduced a pair of category named corporeality and incorporeality, it separated the being and the time, and considered that time is incorporeality, thereby avoided the existence of undermination and imperfection in time, and withdrew the necessity of the existence of non-time. In brief, the world of idea and the invariable substance do not exist.

但斯多亚学派引入实在性与非实在性这对范畴，分离了存在与时间的关联性，认为时间是非实在性的，从而避免时间中存在的易朽和不完善，也就取消了无时间的存在者的必要性，要之，理念世界和不变的实体是没有必要设立的。

In the second place, the migration of industrial population resulted in social vicissitudes of the life style; the daily life was put double marks of immigration and migrancy; the inhabiting style of the apartment made the working places and time separated from the living places and time, strengthening the sense of time of the inhabitants.

第二，工业移民导致了洛阳城市生活方式的社会变迁，日常生活中不仅打上了移民移居的生活烙印，更反映了工业生产方式对生活方式所产生的影响与改变。公寓房的居住方式导致了工作场所和时间与生活场所和时间的分离，这种时间、空间的"二分"提高了居民的时间观念。

She thereby not only underscores time's duration; her implementations in installations, drawings, poetry, and music are especially focused on the repetition and endlessness inherent in the course of time.

因此，她不仅强调了时间的持续时间，她实现了装置，绘画，诗歌和音乐的，尤其是在重复和无穷的过程中所固有的时间集中。

These artists steeped in the rhythm in time, tasting the rhythm of time, enjoying the brilliance and entailment that time brings to life.

这些艺术家浸淫于时间的节奏，品味着时间的韵律，咀嚼和享受着时间带给生命的光耀和蕴涵。

The relationship between the delay in the error path and convergence coefficient and convergence time is emphasized.

重点讨论了弹性波控制中误差传递途径相对于主激励源的时间延迟与收敛系数以及收敛时间的关系，并回归出最佳收敛系数与延迟时间之间的倒数关系。

Results:Whith the time and doses of ART incubation extended, ART significantly inhibited the proliferation of SGC-7901 cells and the inhibited effect shows dose-and -time-dependent. Obvious changes of apoptotic morphology were observed by invert microscope, fluorescence microscope, scanning electron microscope and transmission electron microscope, they showed that cells had marked nuclear condensation or the fragmentation of chromation as well as apoptotic , mitochondrial edema and vesicle , with the time of incubation extended , the proliferation rate become slow and the volume became small and transformed. FCM assay indicated that most of the cells were arrested in Go/Gi and the apoptotic peak appeared. During the prolong of incubation time, the apoptosis rate was increased. At the same time, the number of S and G2/M phase cells were decreased. The result of TUNEL indicant that there are apoptosis and necrosis.

结果：随着药物浓度的增加和作用时间的延长，蒿甲醚对胃癌SGC-7901细胞的抑制作用呈时间和浓度依赖关系：在倒置显微镜、荧光显微镜、扫描电镜和透射电镜下可观察到典型的凋亡细胞的形态改变，表现为：核固缩或染色质边聚或凝聚成大块状，可见凋亡小体，线粒体肿胀增殖，严重的空泡化，随作用时间的延长，细胞增殖速度减慢，细胞体积缩小变形；流式细胞术显示胃癌SGC-7901细胞出现明显的凋亡峰，随着作用时间的延长，其凋亡率逐渐升高，细胞周期阻滞在G_0/G_1期，S及G_2/M期细胞数大量减少；流式细胞术TUNEL检测结果显示细胞凋亡和坏死同时存在。

Firstly, the basic concept and convention about formalized stand language LOTOS is introduced, and, the language was improved and extended by adding discrete time domain and time operator to confirm its syntax and semantics rules.

本文首先论述了形式化规范语言 L OTOS的基本概念与约定，对其进行了基于时间的改进和扩充，引入了离散时间域和时间操作算子，然后确定其相应的语法定义和语义规则，通过仔细分析分布式环境下的多媒体同步问题，基于时间扩充的 L OTOS，给出了一种特殊的多媒体同步系统以及具体的算法描述。

An interview guide entitled,"Maternal Perception of the Onset of Lactation" was also used to obtain milk secretion data. The analytical results revealed a mean onset of lactation of 75.7±16.8 hours (range=40 to 117). The prevalence of delayed lactation onset was 50.5%(n=58); 64.3%(n=42) were primiparous, and 41.9%(n=74) were multiparous. Parity, hours of withholding oral intake post-operation, and use of formula were significant predictors of perceived lactation onset. These factors explained 22.5% of perceived lactation onset in postpartum women who planned cesarean section.

研究结果发现：(1)泌乳起始时间的平均值为757±168小时（范围40至117小时）；(2)产妇自觉延迟泌乳的发生机率为500%(n=58)，其中延迟泌乳的初产妇有27位，占所有初产妇(n=42)的64.3%，延迟泌乳的经产妇有31位，占所有经产妇(n=74)的41.9%，经产妇发生延迟泌乳的机率较低；(3)产次、术后禁食时间以及配方乳使用，是泌乳起始时间的重要预测因子，共可解释计画剖腹产妇泌乳起始时间总变异数的22.5%。
