测高

Most of the molecular characteristic absorption is very weak, and the absorption line width is very narrow that can't be measured by traditional methods.

TDLAS系统的关键是利用激光二极管有很高光谱分辨率和可调谐性的特点，可以对特定分子在特定光谱范围内的一条振转线的光谱吸收进行测量而反演吸收气体的浓度，而且能够把待测分子与背景的干扰区分开来。

This article introduced one kind of high accuracy blackbody temperature measurement electric circuit.

摘 要：本文介绍了一种高精度黑体测温电路。

When researchers looked at male predominance in stroke among preteens vs teens, they did not find a statistically significant difference. However, said Dr. Golomb, the study may have been underpowered to detect a true statistically significant male predominance in this age group.

当研究者针对青少年前期与青少年时，男性中风比例是否偏高时，他们并未发现统计上显著差异；然而，Golomb医师表示，这项研究可能没有足够的统计力量来侦测在该年龄层男性中风比例是否较高的差异。

By synthetically analyzing the variation characteristics of pre-earthquake anomaly before five moderate-strong earthquakes in East China since 1990,discussing the pre-earthquake anomalous shape of b value and so on we obtained the comprehensive criteria for medium and short-term earthquake anomaly before moderately strong earthquake in East China:high YH value anomaly—low b value anomaly—low C and YH value anomaly—low Ds and Dt and Σ value anomaly and high b value anomaly—earthquake.

通过对华东地区1990年以来5次中强以上地震震前异常变化的综合分析，探讨了b值，Ds，Dt，C值， YH值，Σ值震前异常形态，并归纳出华东地区中强地震发生前测震学中短期异常的综合判据：YH值高值异常(主要出现在震前3年前后)—b值低值异常(平均出现在震前2年前后)—C、YH值低值异常(大体出现在震前1～2年前后)—Ds，Dt值低值异常、Σ值低值异常、b值高值异常(主要出现在震前1年内或稍长)—发震的模式。

The steel armored electric cable logging truck owner asked that the truck should consists of electric cable driving machine, goose neck guider, winch, hydraulic driver, depth detector, weighing display, instrument display panel, and data collection system. It can solve the problem of pulling force for the down hole instrument in horizontal, sticky oil and high pressure wells. The practice shows that it is a device with high efficiency, low cost, strong suitability to environment, reliability and safe.?

钢铠电缆测井车主要由驱缆器、鹅颈形导轨、绞盘、液压驱动、测深、指重装置、仪表显示操作盘及数据采集控制处理系统等组成，能解决水平井、稠油井、高压油井等特殊井类在测井过程中仪器下行牵引力的问题，是一个作业效率高、测试成功率高、成本低、适应环境能力强、作业安全可靠、具有环保效益的新技术。

For sample with longer GI time, which resulting in the better uniformity of this sample, the unusual decrease of FWHM is not observed in the measurement of the temperature dependent PL spectra. Considering the better uniformity of the sample, the effect of carrier redistribution on PL spectra is unapparent. Therefore, the FWHM increases gradually with temperature.

对於成长中断时间较长的样品来讲，由於其均匀度较佳，所以在变温的光激光谱量测中，我们并未发现半高宽随温度上升而有下降的趋势，这是因为载子重新分布效应对一个均匀度佳的样品来讲，其显示出来的效果并不明显，所以我们只能观察到电子与声子散射效应所表现出来的现象，也就是半高宽随温度上升而缓慢增加。

And the Multi-Beam Echo Sounder is a seafloor mapping equipment with high efficiency, high accuracy and excellent resolution, especially fitted for wide sweep mapping.
