The tensile properties of under-aged 3J21 alloy at room and low temperatures were studied on a universal tensile teat machine. Moreover, a metallographic microscope and X-ray diffractometer were used to analyze the metallographic structure and physical phase of the alloy in a cold rolled and under-aged state. By employing a transmission electron microscope the structure of the alloy under the above-cited two states was observed and the X-ray diffraction results being verified.

在万能拉伸机上对欠时效态3J21合金室温及低温条件下的拉伸性能进行研究，并采用金相显微镜、X射线衍射仪对冷轧状态和欠时效态的金相组织及物相进行分析，采用TEM观察两种状态的组织和结构，验证了X射线衍射结果。

When you sail to the signal too much interference source areas, the auto-detect mode instantly converted to urban model, and will automatically reduce the sensitivity of X BAND, when the driver left the area too much interference source signals when the automatic mode will be automatically to increase the sensitivity of X BAND.

当您行驶到讯号干扰源过多的地区时，自动侦测模式会瞬间转换到市区模式，并且会自动降低X BAND的感度，当驾驶者离开讯号干扰源过多的地区时自动模式会自动增加X BAND的感度。

Advancement of CT machine: Since CT machine has been applied, with unceasing development of computer technique, detector technique, X-ray technique and new micro-electron and micro-technique have been used, thereby performance of computerized X-ray tomography machine has been improved greatly, it is era-changing identification of computerized X-ray tomography scan from bed plane scan to spiral scan.

CT机的进展：CT机器自问世以来，随着计算机技术，探测器技术，X线技术的不断发展以及新的微电子和显微技术不断的应用于CT机，从而提高了CT机的性能，标志着CT扫描从层面扫描到螺旋扫描的换代。2）图象后处理技术：螺旋CT的出现及计算机软件的开发，利用导航技术做出具有3D仿真内窥镜的图象，既，这种新的影像学方法，引起了广泛的关注。

Histochemical assays of GUS gene showed those resistant callus and roots from transgenic plants cultured under light were no blue-stained with X-gluc, but callus and roots after 24 h treatment of darknees and then incubated with X-gluc could present blue. Fluorimetric enzyme quantitative analyses indicated GUS expression in transgenic plants was organ specificity.

转基因抗性愈伤和转基因植株根的组织化学GUS活性检测表明，光照培养下的抗性愈伤和转基因植株根不能使X-gluc显色，而暗处理24 h后的抗性愈伤和定植后转基因植株的根能使X-gluc显色。

Be honest with yourself(If Coke and Coffee are going to cost X cents a day plan for X cents a day.) If your allowance is supposed to cover such items as new pantyhose,dry cleaning shoe repair oil、gas auto maintenance and so forth budget these costs.

Results: Weight is a more important and accurate factor to predict ETT size in pediatric patients than age. Combining the age and weight can still provide a better result. The formula is as the following: ETT size = 3.207 +(age x 0.074)+ weight x 0.109

结果；我们发现体重比起年龄在预测小儿病患的气管内管大小上是一个更重要且准确的因子，但如果合并体重与年龄一起去做预测可以得到一个更好的结果，最后所得到的公式如下： ETT size = 3.207 +(age x 0.074)+ weight x 0.109
