不准确

Scuttle their plans by zigging instead of zagging, cheerfully accepting any accurate statement they might make while ignoring their malicious energy.

用&过去&而不是&过来&欣然地接受任何他们可能做出的一条准确评价；同时忽略任何恶意能量。这样一来让他们的计划落空。

However, we don't know for sure exactly which genes influence skin.

不过，我们不知道，为确保准确的基因的影响皮肤。

Methods Demirjian′s method was used to assess the dental maturity score and dental age of 445 Chengdu children.

恒牙的形成不会受乳牙早失的影响，因此利用恒牙研究牙龄更为准确和实用。

The number but also ensuring accurate and is not subject to loss of profit and loss occur, you should report the incident to and why, and with the approval of the book, it can only be adjusted.

还要保证做到数量准确且不受损失，如发生盈亏，应说明原因，上报并经批准后才可调整账面。

In this paper Ⅰ successfully applied these methods to fault diagnosis, and presenting some new innovative machinery fault diagnosis method; First Ⅰ present a new gear wornout fault diagnosis method, this method use the vibration signal's time-frequency attribute and instantaneous phase undulation to accurately detect gear's fault, and by comparing with the traditional frequency domain analysis method, this method reveals that many nonlinear and nonstationary characteristic exist in gear's vibration, this tell us that if we use frequency domain analysis method without pay attention to the signal's characteristic, we could get wrong diagnostic result; Then Ⅰ present a new bearing fault diagnosis method, this method use ATVFD and Hilbert transform to do envelop demodulation,Ⅰ analyze the envelop with time-frequency method and find out that this method is more accurate then traditional method.Ⅰ also explain that the modulation of the fault to the carrier wave may also be non-stationary and nonlinear; Finally Ⅰ present a cylinder pressure measurement method of diesel engine by means of vibration, cylinder pressure is an important parameter of diesel engine fault diagnosis, the pressure measuring is simplified a lot by this method,Ⅰ also use the ATVFD and time-frequency analysis to realize it.

本文中将上述理论方法成功地应用到故障诊断中去，提出了几点创新性的诊断方法；提出了一种齿轮磨损故障诊断的新方法，该方法利用振动信号能量的时频域分布特征与瞬时相位波动特征可以进行精确的齿轮故障诊断，并通过与传统的频域诊断方法的比较，揭示出齿轮振动中存在的明显的非线性与非平稳特征，说明了不加选择地利用频域分析方法进行齿轮故障诊断很可能会得到错误的诊断结果；提出了一种轴承故障诊断的新方法，该方法利用ATVFD分解与Hilbert变换进行包络解调，并对解调得到的包络信号进行时频域分析，可以实现更加准确轴承故障诊断，说明了故障对载波信号的调制往往也是非平稳与非线性的；提出了一种利用振动信号进行柴油机汽缸内压力检测的新方法，柴油机汽缸压力的变化是柴油机故障诊断的重要参数，利用振动方法可大大简化汽缸压力的检测过程，该方法也是综合利用ATVFD分解与时频域分析方法实现的。

Following, a experiment has been carried out, the incident waves with a frequency band of 200kHz-3 50kHz are used to the experiment, and a series of peak value-time curves are drawn each 10kHz, corresponding time are found through fitting peak value, thus the position of the defect is calculated accurately. The application of awl-shaped sensor head in the heat change water pipe experiment indicates that the ultrasonic guided waves may transmit nearly 50 meters in the pipe, which is not influenced by the elbows and makes it possible to test defects in long distance and large-scale. The water-load pipe experiment indicates that the displace and energy maybe leakage at the near-surface, which is significant for the further research.

而后，采用200kHz至350kHz频段的入射波进行了实验验证，并每隔10kHz绘出一条峰值一时间的曲线，通过拟合峰值点，找到对应的时间，从而准确的计算出了缺陷的所在；应用锥形探头的热交换水管的实验表明，超声导波可以在管道中传播了近50米的距离，且不受弯头的影响，从而使得长范围、大规模检测成为可能，水载管实验说明了离面位移和能量可能会发生泄漏的特性，为导波的深入研究和应用作了铺垫。

A two-tier overlay network model is presented in this paper. Some consecutive nodes form an unstructured group and different groups are connected by a globally structured overlay with the Chord protocol. The model uses the Hilbert-based level search and the dynamic load balancing policy of a two-tier ring structure on top of the overlay network.This strategy has not only the characteristics of load balancing but also enough flexibility for searching.

Chord模型可以保证搜索系统中特定数据对象的跳跃次数在O的范围内，但只能根据数据对象的键进行准确匹配查询，不支持多关键字、部分关键字、通配符或是参数取值区间组成的复杂查询[1]；其次，相容散列的理论证明了当系统中有N个结点和K个键值的情况下，在每个结点上运行O个虚拟结点时，每个结点的键值范围可以无限趋于K/N。

Actually, calling them bar codes is a bit old-fashioned, because they store information in a two-dimensional (2-D) matrix of tiny squares, dots or other geometric patterns, rather than a stripe of black-and-white lines of varying thickness.

实际上，把它们称作条形码并不准确，因为它是用一个由小方块，小圆点或其它几何图形组成的二维阵列来表达信息，而不是用黑白相间的宽度不等的竖条纹了。

Fluid pattern is suitable for NMR porosity calibration in Berea sandstone as well as terrestrial sediment sand with little shale content and well sorted. Ceramics reference material is applied to shaly sand with average sorted. Both fluid pattern and solid ceramics material are not suitable for calibration in sandstone sample with high clay content, complex lithology with rich paramagnetic materials.

流体标样适合于贝瑞砂岩、陆相沉积分选好、泥质含量低的砂岩NMR孔隙度的标定；固体陶瓷标样适合于分选中等的泥质砂岩NMR孔隙度的标定；对粘土含量高的砂岩、含顺磁性物质的砂岩和砾岩等复杂岩性岩样，用流体标样和固体陶瓷标样标定都得不到准确的NMR孔隙度值。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
