查询词典 a mass of

1 Self-threading or sheet metal screws may be used if threads are not stripped when the screw is tightened with a torque of 3.39 N·m (30 lb·in) and if the part or the assembly supported by the screw withstands for 1 min a force equal to four times the mass of the part or assembly, applied in a direction coincident with the axis of the screw.

The second planet from the sun, having an average radius of 6,052 kilometers (3,760 miles), a mass 0.815 times that of Earth, and a sidereal period of revolution about the sun of 224.7 days at a mean distance of approximately 108.1 million kilometers (67.2 million miles).

金星：离太阳第二远的行星，它的平均半径为6，052公里(3，760英里)，质量是地球质量的0.815倍，它在离开太阳约为108，100，000公里(67，200，000英里)的中等距离时绕太阳转的公转周期为224.7天

A measuring approach of pressure oscillation has been developed and experiments are conducted in a 10 liter two-dimension air-lift loop reactor. The experimental results show that the local mass transfer parameters have close relationship with the operating conditions, the structure of ALR and the properties of the reaction systems. A series of measurements of pressure pulse indicate that a gas distribution zone exists near the gas sparger, and in this zone the responding signals of pressure pulse are different with the signals measured in other parts of the reactor.

对不同结构的环流反应器的局部流体动力学和传质动力学特性进行了研究，利用压力传感器测量了空气-水、空气-NaCl水溶液、空气-Na〓SO〓水溶液、空气-葡萄糖水溶液和空气-乙醇水溶液五种体系，在不同气速下，不同位置的压力脉动信号，通过随机信号的数学分析，得到压力脉动信号的频谱特性，并依据压力脉动信号的频谱特性的分析给出环流反应器气体分布区的范围。

The broidered and dentated cordon of the eight and twenty royal niches; the immense central rose window, flanked by its two lateral windows, like a priest by his deacon and subdeacon; the frail and lofty gallery of trefoil arcades, which supports a heavy platform above its fine, slender columns; and lastly, the two black and massive towers with their slate penthouses, harmonious parts of a magnificent whole, superposed in five gigantic stories;--develop themselves before the eye, in a mass and without confusion,with their innumerable details of statuary, carving, and sculpture, joined powerfully to the tranquil grandeur of the whole

那镂刻着二十八座列王雕像神龛的锯齿状束带层，那正中巨大的花瓣格子窗户，两侧有两扇犹如助祭和副助祭站在祭师两旁的侧窗，那用秀丽小圆柱支撑着厚重平台的又高又削的梅花拱廊，还有两座巍巍、黝黝的钟楼，石板的前檐，上下共六大层，都是那雄伟壮丽整体中的和谐部分，所有这一切，连同强有力依附于这肃穆庄严整体的那无数浮雕、雕塑、镂錾细部，都相继而又同时地，成群而又有条不紊地展现在眼前。注意，注意力集中

Adams argued for a definition of civilization as a society with functionally interrelated sets of social institutions: class stratification based on the ownership and control of production, political and religious hierarchies complementing each other in the central administration of territorially organized states and lastly, a complex division of labor, with skilled workers, soldiers and officials existing alongside the great mass of peasant producers.

Adams 提出"文明"的定义应当是把它看成是一个社会，在其中有一套相互之间有机联系着的社会结构：基于产品所有者和控制者的等级阶层，在国家的核心管理上相互配合的政治阶层和宗教阶层，由技术工人、士兵和同绝大多数的农业生产者生存在一条水平线上的公务员所组成的复杂的劳动者联合体。

The acceleration is indispensable as a state-variable for precise analysis of the dynamic response of a drive system. This is because it represents the direct, undelayed response of a mass being moved in reaction to all the forces acting on it.

加速度是必不可少的一对驱动器的系统，这是因为它代表着直接的，毫不拖延地的群众正在反应，反应的所有部队行事提出精确的分析动态响应状态变量。

Chapter 11 gives a detailed account of the various forms of mass spectrometry and includes a discussion of its use in protein structure determination, an application unthought of only a few years ago.

第十一章详细讲述了各种形式的质谱仪，并讨论了它在蛋白质结构分析中的使用，仅在几年前才出现这种不成熟的应用。

Objective To investigate the curative effect of left ventricular hypertrophy with uretic indapamide, Methods 96 patients wiht LVH were divided into two groups, 50 patients in A group were treated with indapamide 2,5～5mg/d, and 46 patients in B group with nifedipine 20～60mg/d for 12 months, Results Blood pressure、interventricular septum thickness、left ventricular posterior wall thickness、left ventricular mass index and left ventricular ejection fraction in all cases were improved after treatment, A group was better than B in LVEF, Conclusion Both indapamide and nifedipine can regress LVH, and improve left heart function

目的 观察新型噻嗪类利尿剂吲达帕胺逆转左心室肥厚的效果。方法 96例高血压LVH患者，分别给予吲达帕胺(A组，50例)2，5～5mg/d和硝苯地平控释片(B 组，46例)20～60mg/d持续12个月治疗，观察治疗前后血压及左室结构变化。结果两组治疗前后血压、室间隔厚度、左心室后壁厚度、心室重量指数和左心室射血分数均有改善(P＜0，05～0，01)，A组在改善LVEF方面优于B组(P＜0，05)。结论吲达帕胺具有与硝苯地平类似的逆转LVH作用，有明显改善左心功能作用。
