到差

In other words, when the fundamental frequency is 440 Hz, we have a pitch of 69 semitones, which corresponds to "central la" or A4 in the following piano roll.

换句话说，当基本频率是 440 Hz 时，对应到的半音差是 69，这就是钢琴的「中央 La」或是「A4」，请见下图。

Certainly some of the seediest of journalists, whether we're talking about the Middle East or Northern Ireland, are those who pile on one set of adjectives --- squalid, butchering, oppressive --- for terrorism of whose aims they disapprove, and quite another set committed, dedicated, idealistic --- for the same thing done by those they like.

可能有些道德极差的记者，不管我们谈到中东或北爱尔兰，都堆砌了一大套形容词，像卑鄙，残忍，不公正用于形容恐怖主义，因为他们不支持其目的。另一风格的词语如忠诚，热忱，理想主义等用来形容同样的事情，只不过因为他们喜欢做事的人。

The results showed that compared to participants of other three groups, neglect patients produced significantly more errors, longer reaction time, and greater number of saccades. They started their search to the left or right of the middle and employed inefficient search strategies. In particular, neglect patients performed worst when the target appeared on the far-left visual field.

实验结果发现，除跳跃眼动的平均长度外，忽略症病患的各项表现皆显著较差：他们均容易忽略患侧空间的目标物；即使可以侦测到，其反应时间和跳跃眼动的数目皆显著增加，主要从近端的两个区域开始扫描，且无法采取较一致且有效的策略来侦测目标物。

First, based on the measurements of absorption cross-section, the absorption characters of the main polluted gases in flue gas were deeply studied, and found that SO_2、 NO、 NO_2、 NH_3 had a character of approximate periods absorption at some wave band, which is a good chance of a new measurement introduced. Secondly, the factors about absorption cross-section of the gases measured, which affect on the measurement precision of DOAS, is studied deeply. The influence of pressure and temperature on absorption cross-section was given special research, and the compensated measures were given to the gases based on the character of the gases. Thirdly, in practical measurement, it must have been satisfied that the monochromator was consisted with the reference spectrum, which was based on absorption cross-section. In order to satisfy the consistency, the technique of reversion in the image was introduced, the reversions of spectrums were realized with wiener filter and noise elimination based on wavelet transform.

首先从吸收截面的测量入手，对烟气中主要的污染气体SO_2、NO、NO_2、NH_3的吸收特性进行详细研究，发现这些气体在局部区域具有准周期吸收特征，这为引入新的测量方法提供了契机；其次，对决定DOAS测量精度的被测气体吸收截面的诸多问题进行了深入研究，重点研究了压力、温度对被测气体吸收截面的影响，并针对被测气体的特征提出了相应的修正措施；再次，在实际测量中，要求所使用的光谱仪必须与以吸收截面为基础的参考光谱相匹配，为了满足匹配这一条件，文中将图像复原技术引入到光谱复原，使用维纳滤波和小波消噪实现了光谱的复原，将复原后的光谱与所使用光谱仪的仪器函数卷积，即可实现；最后，在对DOAS测量原理详细分析的基础上，对传统的最小二乘—差分吸收光谱法进行了详细的阐述，通过实验证实两点：1。

During the operation of cold reclaiming for asphalt pavements, water content in aggregate has a direct influence on reclaiming quality of the road mat. The spraying systems on existing domestic cold road reclaimers are poor in control accuracy, complicate in operation and low in reliability.

沥青路面的冷再生施工过程中，混合料的含水量直接影响到路面结构层的再生质量，现有的国产路面冷再生机喷洒系统控制精度低、操作复杂且可靠性差。

You should aim for pin point accuracy the difference between victory and defeat can be as little as one centimeter.

你必须正确地瞄准这些点--成攻与失败的差别是几乎不到一厘米。

To be frank, our guys are still working with sigma engineers together to pin point the issue which affects the 3% of players.

坦率地说，我们的球员仍然与标准差的工程师一起，针点的问题，影响到3％的球员。

While a ball mill is working, balls in the mill are lifted, and then are thrown away with a certain velocity to collide raw material. But at the same time, balls and underboarding are also got collision which may make balls and underboarding fracture. Considering the tough lubrication condition and dust and prills have easy access to meshing zone of gears, the heavy abrasion on gear surface often appears in the upstage gear of open-gear transmission of ball mill.

当球磨机正常运转时，磨球被提升到一定高度后抛落，以一定的速度对物料产生冲击而粉碎物料，同时也对磨球和衬板自身产生冲击，这可能造成磨球和衬板的破球磨机的末级开式齿轮传动，由于润滑条件差，粉尘、金属颗粒容易进入啮合区，齿面常常出现严重磨损，导致齿廓形状发生变化，最后因齿厚磨损过多而折断。

See not hard, the website that supports network sale needs to want to have sale function, namely the stage before the website needs to want process of sale of as politic as the business of target market 、 of the enterprise 、 to match effectively, jiang is connected so outstanding a delivered sale information, remove to go up to the website, raise the tiring-room that delivers website of; of limits He efficiency to be able to manage the look inside client He from this, run state of good client account, can provide the look inside poor dissimilation for different client, jiang pole heightens sale effect greatly can.

不难看出，支持网络营销的网站需要具有营销功能，也就是网站前台需要与企业的目标市场、业务策略、营销过程有效匹配，将原来通过人员传递的营销信息，搬迁到网站上，由此提高传递范围和效率；网站的后台能够管理客户和内容，管理好客户状态，能够为不同客户提供差异化内容，将极大提高营销效能。

According to the function of distributed emulator, optical information processing and image multi-object tracking system, the following three aspects were emphasized in this dissertation. Firstly, a vast virtual terrain, ground radar models and canyons were created for the distributed emulator with modeling software Creator. The radars were driven to scan during emulating and the real time terrain code was sent to Radar module. Secondly, an optics channel simulating the optics camera of a virtual aircraft was implemented with simulating software Vega. The 2-D information got from the channel was translated and sent to multi-sensor information fusion system as an optics information source. Thirdly, the dissertation studied some motion estimation methods and analyzed the factors which influence the speed and the precision of the block matching algorithms. Then an improved block matching method was proposed for image multi-object tracking system and applied in the system combined with frame difference method.
