小周期

Retch, like hiccups, as has been for 3 days.

我是8月30号的月经，周期31天，9月13、14、16号有makelove，这2天没什么胃口，嘴巴里也没有味道，小腹胀胀的，老是干呕，像打嗝一样，已经连续3天了。

The preparation fixed separately at dawn, t noon at dusk and night, was studied. It was observed that the fine structure of the retinular cell changed with day-night rhythm.

在黎明、正午、黄昏和夜晚4个时时间点观察到，其小网膜细胞的结构随昼夜光周期发生节律性的变化。

Dr. Sheau-Farn Yeh's lab found that taiwanin A, isolated from Taiwania Cryptomeriodes, is cytotoxic for several cancer cell lines, especially for human hepatoma Hep G2/A2 and Hep 3B/T2 cells. Besides cytotoxicity, the compound can arrest the cells at G2/M phase. Not only taiwanin A and its derivatives, but also compounds which isolated from the plane Clausena excavata and the roots of Rubia cordifolia have been found to have biological activities.

阳明大学生物化学研究所叶小帆老师实验室在筛选天然抗癌药物时，发现自台湾杉心材所分离出的一种化合物taiwanin A对於许多的肿瘤细胞株均有很强的细胞毒性，其中对人类肝癌细胞株Hep G2/A2与Hep 3B/T2，taiwanin A除了有显著的细胞毒性之外，同时也会造成细胞周期停滞在G2/M相。

Some solvability conditions, including sublinear ,subquadralic and superquadratic, and the corresponding existence results are summed up for periodic solutions of the second order Hamiltonian systems obtained by using the minimax methods.

本文综述了用极小极大方法得到的关于二阶Hamilton系统周期解的可解性条件及相关结果，包括次线性条件，次二次条件和超二次条件等方面的近期结果。

The species structure and importance value dynamics of annual plants in herbage synusia during a growth period have been observed, and the ecological mechanisms of these changes have been analyzed also.

通过跟踪观测一年生植物层片在一个生长周期内种类组成及其重要值的变化，并分析变化的生态学机理，得出如下结论：①在固沙区草本层片内，小画眉草的多度、盖度和重要值在群落中所占比例较大，是群落优势种；②在充足的降雨后，一年生植物都突发性萌发，但随着降雨的减少，层片内的一年生植物种群都呈衰退之势，其中小画眉草和虎尾草种群急剧减少，狗尾草、雾冰藜和虫实种群减少幅度不大。

Methods Human prostate cancer PC-3 cell, breast cancer ER-75-30 cell and lung cancer A549 cell were cultured in RPMI medium 1640.Light microscope,transmissional electron microscope, flow cytometer and immunohistochemical method were used to observe apoptosis morphological changes of three kinds of tumor cell lines, time and dose effect relationship and to detect expression of bcl-2 and bax.

方法人前列腺癌 PC-3细胞株、乳腺癌 ER-75-30细胞株和非小细胞肺癌 A549细胞株经培养后，采用光镜、电镜、流式细胞仪和免疫组化方法研究 188Re诱导 3种肿瘤细胞凋亡的形态学变化、时间剂量效应关系、细胞周期依赖性以及凋亡相关基因 bcl-2和 bax在其中的表达情况。

Suspensorily joined structure has the virtue that the construction progress is normally fast and does not hinder the traffic underbridge because Travelling Carriage is not used,but requiring comparatively large construction plant, high complexity in seam assembling, lower structural integrity compared to the suspensorilyplaced are its faults.

预应力混凝土T型刚构加挂梁结构是公路桥梁常用的一种桥梁结构型式，这种桥型根据施工方法的不同可分为悬浇和悬拼，悬浇结构需采用挂篮施工，优点是结构无干接缝，整体性好，刚度大，施工占用场地少，缺点是施工期间挂篮将影响桥下的通航通车，施工周期长；悬拼结构的优点是无需采用挂篮施工施工进度快，对桥下的通航通车影响较小，缺点是需占用较大的施工预制场地，拼装接缝处理难度大，结构整体性较悬浇差。

As compared with undrawn PET film, the hot drawn PET film showed shorter crystallization induction period, faster development of long period, anisotropic in SAXS and WAXD patterns, with considerable thermal contraction along the direction of drawing and small lengthening in the direction of drawing during crystallization.

研究结果表明：热拉PET膜的结晶诱导期较短，长周期发展得较快，结晶后小角X-线散射表现出明显的各向异性，在热处理过程中先出现显著的热收缩，随后又表现出结晶伸长现象，这些都和未拉试样有明显的差别。

For 2p〓-periodic binary sequences, a new weight function, according to the above presented vector expression of the linear complexity, is defined. By analyzing the weight of the product of a special kind polynomial in finite field, the upper and lower bounds on minimum error, expressed by the here denned weight of the linear complexity, are given in different cases.

对于2p〓-周期二元序列，利用所给出的线性复杂度的向量表示定义了一种新的重量函数，通过研究有限域上一类特殊多项式乘积的重量，分情况给出了用线性复杂度的重量表示的最小错误minerror的上界和下界，这里的重量是由我们所定义的重量函数确定的。

"Stars: Their Birth, life, and Death" is the result of a lifetime of work in the solar realm, embracing the full solar cycle but evincing none of the alleged deficiencies of composition at solar minimum.

恒星的诞生、发展和死亡》一书是著者在恒星领域里工作一生的结果，经历了太阳活动周期的所有相位，然而却丝毫看不出所谓在太阳活动极小期缺乏特色的迹象。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
