环境噪声

In the environment where it is higher than thermodynamics zero degree, current pulse of faitness is produced by the movement electron in the resistance, it forms the noise current of resistance by addition, the higher the temperature in resistance is, the acuter the electron movement will be, the bigger the noise current will be, therefore the resistance of the thermal noise current is formed.

The results showed that the most worthy of being noticed were the attitude of first-line safety supervisors and the uniform equipping of personal protective equipment, improper operation and maintain of machines, and high temperature and noising.

结果表明：安全管理最值得关注的问题为安全员的工作态度和防护用品的统一配备，设备的操作不便和维修、调整、保养不良较为突出；作业环境严重的危险因素则是高温和强噪声。

The image acquisition of weld seam is influenced by the intense spatters combusting gas, arc and the noise.

获取的图像中存在大量的飞溅、烟尘、电弧光以及周围环境电磁、静电产生的噪声干扰。

However, the automobile environment is noisy, and it is not clear that verbalizing a command, especially if it needs to be repeated or corrected for, is any less cognitively demanding than pressing a button.

不过，由于汽车的环境可能比较噪声很大，有时很难识别语音命令，有时需要重复或者更正，这就没有按键来得准确。

With globally industrial development there are often corrosive and harmful gas volatilizing in the course of production, detection,and experiment, which does harm to human health.

随着全球工业的发展，在生产、检测和实验过程中，经常有腐蚀性和有害气体挥发，危害着人们的身体健康，为了保证良好的工作条件和环境，必须有良好的通风设备，本公司生产的4-72型、4-62型玻璃钢通风机得到了广泛的应用，它具有耐腐蚀性能好，防雨、防晒和良好的理化性能，强度高、体积轻，排污效率可达95％以上，噪声LSA在25分贝以下，节能、运转平稳等特点。

In order to advance the capability of correlation signal detection method, a new method for LFM signal detection,based on the technology for ambiguity resolution of stagger repeated frequency, is proposed. Using the method, the signal in low signal-to-noise ratio can be detected very well and its parameters can be estimated more precisely too.

本文提出基于重频参差解模糊技术的信号参数估计方法，通过相位解模糊，实现了在低信噪比条件下对信号参数更有效地侦取，并对处于白噪声环境下的窄带和超宽带LFM信号进行了仿真，验证其有效性。

For the complexity of face detection environment, this paper proposes a face detection algorithm which based on skin color and support vector machines .for color picture of face which has complex background information, the algorithm uses skin color detection to divide area of skin color ,and to wipe off the noise interference, then do further examination for the same area of skin color and confirm the face area used by support vector machines.

针对人脸检测环境的复杂性，该文提出了基于肤色和支持向量机的人脸检测算法。该算法对于具有复杂背景信息的人脸彩色图像，采用肤色检测的方法进行肤色区域的分割并去除噪声干扰，然后使用支持向量机对于类似肤色区域进一步检测并确定人脸区域。

Integrating the sound intensity vector on the area which surrounds a sound source gets the sound power of this sound source. Since the integral of the sound power of the sound sources which are not enclosed by the area is zero, one could measure the sound power in ordinary environments correctly by measuring sound intensity.

对于一个声源，只要将其包络面上的声强矢量作积分，就可以求出被围声源的声功率，而测量区域之外的干扰噪声得以抵消，因此可以在普通环境下能准确地测定声源声功率。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
