周期性的

Based on our inventory, capacity utilization, as well as changes in earnings growth forecasts, for a cyclical industry, in 2008 Q4 and 2009 are 1,2-quarter inventory digestion a painful process , production dropped to historically low interest rates, profits have been seriously affected, and even loss of the entire industry.

根据我们的库存，产能利用率，以及在收益增长预期的变化，一个周期性的行业，在2008年第四季度和2009年为1，2季度的库存消化一个痛苦的过程，生产下降至历史新低利率，利润受到严重影响，甚至对整个行业的损失。

In the analysis of dynamics cutting angle, the following phenomenon is discovered first time: the minimize of dynamics clearance angle is not monotone decreasing with the vibration frequency , and appear peak value periodically, which exist is the disseparation region and approach the separation region.

在对振动钻削中切削刃上各点的动态角度的分析中，首次发现在振动钻削过程中动态后角的最小值不是随着频率或频转比的增大单调下降，而是周期性的出现波峰值，这些波峰值都出现在不分离区，而且是接近于分离区处，这是由振动钻削过程中的变速特性引起的。

The 0°K relaxed structures of grain boundaries in Cu and its alloys (Cu-Ag, Cu-Bi) were simulated with molecular dynamics method by using a five-parameter potential and constant volume assumption.In these cases, the results showed that the atomic distribution was periodic in the two directions paralled to the grain boundary and it was mirror-symmetric in the direction perpendicular to the boundary.

本文采用五参数对势和固定体积的假定，应用分子动力学方法模拟了零温下纯Cu、Cu-Ag和Cu-Bi合金的晶界弛豫结构，计算结果表明，在上述情况下，原子分布在平行晶界面的两个方向是周期性的，在垂直晶界面的方向是镜面对称的。

The basic regulation on the changes in amount of organisms in animals was expressed by the fact that the percentages of erythrocytes being infected increased rapidly op to 96-98% 2-4 hours after infection, then it dropped down and followed by dropping and re-rising, attaining its climax up to 8 hours after infection. Finally, it reflected a fluctuating cycle of 14-16 boors.

结果 附红细胞体在－20℃下保存835d，在4℃下保存205d，仍有一定的活力；猪附红细胞体可以感染小白鼠而不能感染鸡；附红细胞体在动物体内变化的基本规律是在感染后，2-4h RBC的感染率迅速上升到96%~98%，然后下降又上升，在感染后第8h再次达到高峰，最后呈现周期性的上下波动，波动的基本周期是14-16h。

Under electron microscope at 8 and 12 weeks, there were mature transparent cartilages in the repaired tissues, and there were irregularly arranged slight, even and non-periodical collagen Ⅱ in surrounding.

电镜下：8，12周，修复组织中可见多数成熟的透明软骨细胞及其周围排列不规则的、纤细的、均匀的和无周期性的Ⅱ型胶原。

In the past "stuff" stocks were cyclical, their margins played a very predictable foxtrot of bouncing together with the whims of the US economy.

在过去，原材料类的股票是周期性的，它们的利润率是可以预见的狐步舞，随着美国经济的起落而波动。

It is disadvantageous to stability of lunar rover.The frequency of wheel wave is a function of velocity of wheel motor, dimension of wheel,density of grousers and wheel slide.

车轮在垂直地面上的周期波动和前进速度的波动对于月球车来说是一个周期性的激励，其频率应与月球车系统的固有频率避开，防止月球车前进时产尘较大的振动。

Regular staff feedback sessions and luncheons, listening to their comments and relentlessly working towards ensuring that we provide a healthy work and living environment for them, is another key factor that will help improve retention and loyalty towards the Hotel.

举办周期性的员工会议和总经理午餐会，听取员工的反馈意见。确保为我们的员工提供健康的工作以及生活环境，这同时也是减少员工流失率和提升员工忠诚度的另一个重要因素。

In December 2012 the lengthy era ends and the complicated, cyclical calendar will roll over again to Day Zero, beginning another enormous cycle.

在2012年12月的漫长时代的结束和复杂的，周期性的日历将再次推出了零日，开始了又一个巨大的循环。

Here we report a 22year-old man who suffered from recurrent fever accompanied by chest and abdominal pain for more than 10 years. The attack frequency was about once per 23 weeks. Although he consulted many clinics and even received appendectomy at the age of 15, no definite diagnosis was given. During the admission, many laboratory examinations failed to show any abnormality except mild leukocytosis and elevated C-reaction protein. Image studies including chest X ray and abdominal CT scan showed negative result but, interestingly, Gallium-67 scan showed a hot spot in right lower chest and right lower abdomen. After prophylaxis with colchicines 1.0 mg per day, he has enjoyed more than 2 years without the above symptoms.

本篇报告发表一位22岁的男性，十余年来每隔二三周即发生周期性的发烧，浆膜炎；虽然他遍访数家医院，并且在十五岁时被诊断为阑尾炎，并接受开刀治疗，还是没有得到正确的诊断与治疗，此次住院当中，除了稍微的白血球与C-反应蛋白偏高以外，很多实验室检查皆正常，影像学检查包括胸部X光，腹部电脑断层均正常，但有趣的是Gallium-67扫描发现在右胸及右下腹出现强烈反应，经诊断为地中海热后给予秋水仙素预防性治疗，病人已经超过二年没有复发。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.
