运动的

Impersonally the happening of the movement is because of lack of experience in construction and acknowledge of the speed , phase, and rule of the socialist construction.

大跃进"运动的发生，从客观上讲，是由于我国缺乏社会主义建设的经验，对社会主义建设的阶段、速度、规律认识不足；从主观上讲，是由于最高决策层，主要是作为领袖的毛泽东的错误决策造成的；从精神因素讲，由于"左的急躁冒进思想作崇，起了导向作用，而在这种错误背景下形成的歧变、偏误的群众心理，对大跃进运动起到了一定程度的推波助澜作用。

Ecr could promote the gastrointestinal motility, which has some dose-effect relationship. The effect on the gastrointestinal motility of Ecr has no significant difference with the domperidone and prepulsid. The mechanism may be that Ecr could affect the activity of the DVC in the spinal cord, and sequentially the activity of pneumogastric nerve were regulated.

白萝卜提取物对胃肠动力有较为明显的促进作用，这种促动力作用存在着一定的量-效关系；白萝卜提取物促进胃肠道动力的作用与经典的促胃肠动力药物对比没有显著性差异；白萝卜提取物促进胃肠动力的作用机制存在通过对支配胃运动的延髓迷走复合体的激活作用，进而调节迷走神经而实现其对胃运动的调节。

目前的研究成果主要涉及到风沙输运的输沙率的预测、沙粒和风场的空间分布规律、风沙运动的起动机制和维持机制、沙波纹的产生和发展机制以及地表物理性质的改变对风沙运动的影响等。

The vibro-impact systems are familiar with the non-smooth dynamic systems.The dynamics research of the vibro-impact systems not only is significant in theory but also has practical values in engineering.Firstly,using the Poincaré map method,we get an existent criterion of single impact period-n motion in a two-degree-of-freedom vibro-impact system with damper.It is shown that our conclusions are valid through the numerical simulations.Moreover,the satiability of periodic motions is studied and the correspon...

基于Poincaré映射的方法，通过解析的方法导出了一类具有阻尼的两自由度碰撞振动系统的单碰周期n次谐运动存在性判据，经过数值模拟验证了理论分析的正确性，并给出了分析其稳定性的判别公式，通过数值模拟，讨论系统的局部分岔与全局分岔，同时比较了系统参数变化对其周期运动的影响，发现在强阻尼、弱激励、小质量比、较大恢复系数下系统将会出现较多的有规律的周期碰撞。

Objective: To investigate the effects of sulindac on the growth and motility of ovarian cancer cell SKOV3 and its involved mechanism. Methods: In order to detect the effects of sulindac on cultured SKOV3, sulindac with different concentration and untreated control were set up. The changes in morphology of SKOV3 were observed by phase contrast microscopy. MTT colorimetric assay was used to study the effects of sulindac on SKOV3 cell growth. Motility of SKOV3 was determined by scarification assay.

As Darwin was an eminent scientist, his findings were taken seriously and the evidence he presented generated scientific, philosophical, and religious discussion. The debate over the book contributed to the campaign by T.H. Huxley and his fellow members of the X Club to secularize science by promoting scientific naturalism.

由于达尔文是一位杰出的科学家，他的研究结果受到重视，他提出的证据引发了科学、哲学和宗教领域的讨论。T·H·赫胥黎和他X俱乐部的同事发起了通过科学自然主义的科学还俗运动，关于这本书的争论有助于该运动的开展。

The equipment has crept forward in its technology since Robin and his merry men had the run of Sherwood Forest, but the sport of archery remains essentially unchanged, A recurve bow coated in fiberglass has become standard, and arrows made of aluminium and carbon graphite can travel more than 240km/h, but the most important repuirements are straight forward: steady hands, strong shoulders, flexible muscles, sharp eyes and nerves of steel.

与罗宾汉和他的手下在舍伍德森林中占山为王的时代相比，射箭运动的器材装备在技术上已经逐渐进步不少，但是这项运动在本质上并没有改变。覆盖着玻璃纤维，向内凹进的弓已经成为了标准用具，用铝和石墨制成的箭时速可高达240公里。然而，最关键的要求还是那么简单：稳健的双手、强有力的肩膀、柔韧的肌肉、犀利的眼睛和钢铁一般的神经。

The national defence basic project as background and the dynamic model of cotrolled transfer matrix for multiple launch rocket was created in order to reduce the initial disturbance of rocket projectile. The causes that affect the angle change of orientation locator were analyzed by the engineering system dynamic theory base on multibody system transfer matrix method. The simulation of dispersion for multiple launch rocket was implementation, and the affect law between the angle of elevation and side deflection and the control parameters was acquired. The control module was installed on the orientation locator of multiple rocket launcher to control the initial disturbance of rocket that provide new method and theory base and show the engineering system dynamic base on the multibody system transfer matrix method is effective.

The function of enclosure was to enable the dispersed fields of a landowner in a single parish to be concentrated without increasing and decreasing in the proportion before and after enclosure; Enclosure was the precondition of the estate structure in the late 19th century, while the main motivation and approach of that was social mentality and estate market; In the estate structure of late 19th century, agent was the main actor to manage the large and middle estates; Landowner, tenant farmer and agricultural labour affected and restricted each other, which was full of tender feelings.

圈地运动的作用只是使土地所有者在单个教区内分散的土地几乎数量不变地集中到一起；小土地所有者不仅没有消失，而且在1780-1832年间圈地进行最为剧烈的时期出现了数量增加的状况；圈地运动为大地产的形成创造了前提，十八、十九世纪土地流动的主要动因和途径则是大众的心态和市场的激励；在19世纪晚期地产结构中，大、中地产的管理主要是通过代理人体系进行有效的运营；地主、农场主、农业工人三者之间相互影响、相互制约，充斥着温情。

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。
