混时间

Hard surfaced rooms will have a longer reverberation time than rooms finished with sound absorbing materials.

硬地间将有一个较长的时间比房间混响吸声材料与成品。

Absorption- One of the advantages of Topakustik is that you can select from a wide variety of designs to provide absorption in a specific frequency range or over a broad range of frequencies to fine tune the room's reverberation time.

吸收的好处之一topakustik就是，你可以选择各种各样的设计，以提供吸收某一特定频率范围内或以上的频率范围微调房间的混响时间。

Reverberation time is a physical quantity for describing the degree of sound attenuation in enclosures, and it is also an important objective estimate parameter in sound quality design.

混响时间是描述封闭声场内声音衰减快慢程度的物理量，也是音质设计中的一个重要客观评价参数。

Experimental results validate that our proposed method for calculating the receiving radius can be used to predict some acoustical indexes such as the sound pressure level and the reverberation time in an enclosure.

实验表明，所提出的接收球模型能用来较准确地预测闭空间里的声压级和混响时间等声学参数。

As the most important objective parameters,reverberation time and clarity play significant roles in acoustic field characteristics evaluation of the hall.

目前有关混响时间和清晰度等音质参数测量比较成熟的方法是通过测童房间的脉冲响应函数，然后利用反向积分等方法获取l卜2】。

According to Sabin formula, reverberation time value of this model is calculated using AutoLISP language.

基于赛宾公式，利用AutoLISP语言编写命令，计算混响时间。

It is revealed that acoustic quality is an important consideration in these buildings, and it may vary considerably with the same objective acoustic indices such as sound pressure level and reverberation time.

分析表明了声品质在这类非声学建筑中的重要性，另外，即使客观指标例如声压级和混响时间相同，声舒适度亦可能完全不同。

This paper proposed a modified Particle Swarm Optimization algorithm to solve the mixed model assembly line sequencing problem in discrete space with two objectives:total production rate variation and total idle-overload time.

提出在离散空间用一种改进的微粒群优化算法来解决混流装配线的多目标排序问题，考虑两个目标：总生产变化率最小和总闲置－超载时间最小，并对两个目标函数进行了规范化处理以消除量纲的影响。

The investigation has declared that the fuel injection with BQ fuel pump had higher injection pressure, bigger fuel supply rate and shouter fuel supply duration, which would cause the fuel injection quantity and the fule-air mixture to increase during ignition delay period, the pre-mixed combustion to become acutely, and finally result in increased power levels of noise.

研究表明，装配BQ喷油泵，喷油系统的喷油压力较高，供油速率较大和供油持续时间缩短，使得滞燃期的喷油量增加，滞燃期内形成的可燃混合较多，预混燃烧剧烈，导致整机噪声声功率级增加。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""

客人们在卡罗利娜·埃凯家里，举止就文雅一些，因为卡罗利娜的母亲治家很严厉。
