发现

From the photophysical behaviors of 1, 3, 4-triaryl-2pyrazoline compound (TPP16) at low temperature, it can be considered that the twisted configuration between pyrazoline ring and the non-substituted phenyl group on the position 1 is the fluorescence configuration of conjugated system Ⅰ, and the twisted configuration between pyrazoline ring and P-nitrobenzene group is fluorescence configuration of conjugated system Ⅱ.

研究了1，3，4-三芳基-2-吡唑啉化合物TPP16在低温时的发光情况，发现：在低温77K下，共轭体系Ⅰ(苯基-N1-N2＝C3-苯基)在非极性溶剂中不发荧光，在极性溶剂中有较强荧光发射；而共轭体系Ⅱ(N1-N2＝C3-C4＝对硝基苄叉)在非极性溶剂或极性溶剂中均有荧光发射，表明N1所联取代基与吡唑啉环相扭曲的构象是共轭体系Ⅰ的发光构象，而对硝基苄叉与吡唑啉环相扭曲的构象是共轭体系Ⅱ的发光构象。

In the heading stage and milking stage, the inferring ability of logarithm adding obviously surpasses that of SPAD value.

发现：在抽穗期和灌浆期，对数相加模型的反演能力明显优于SPAD值的反演能力。

It is found that in the presence of butyl titanate or stannous oxalate as a polycondensation catalyst the carboxyl content is not always on the increase in all high vacuum stage.

发现，钛酸四丁酯或草酸亚锡作为缩聚催化剂时，在整个高真空阶段羧基含量并不是一直增加的。

To understand it, the ideas and the spirit of the time should be focused on through the specific institutions and ways, rathejust supe rficially settle over them.

学习、理解《科学管理原理》，不能仅停留在对其具体制度和管理方法的表面解读，而应该透过这些制度、方法，发现《科学管理原理》的本质、理念，挖掘其时代的精神。

Results TEE was used to help positioning the RFCA catheter's tip and evaluated possible complications in all patients, guided transseptal catheterization in 3 patients, and found transient moderate mitral regurgitation in 2 patients during RFCA.

TEE引导了全部患者消融电极的放置和位置调整；引导穿房间隔术和穿隔后的电极放置3例；发现 2例消融过程中出现中度二尖瓣反流，及时调整消融电极位置后反流消失。

Comparing size distribution of trace elements at haze weather and the normal weather discovered that,Ca、Ti、Fe、Cr showed significant enrichment in the small size particle at the haze weather:Cu,As didn't have different at such two kind of weather conditions;Zn、Mn、Pb appeared bimodal even trimodal distribution,whose suggested that there were a long distance transmission in originations of such three metals.

对比正常天气下的金属元素的粒径分布，发现：Ca、Ti、Fe、Cr 等元素在灰霾发生时细粒径上有明显的富集： Cu、As 在两种天气条件下区别不是很大：Zn、Mn、Pb 等元素在两种天气条件下均出现双峰甚至多峰分布。由此推断 Zn、Mn、Pb 的来源中可能存在长距离传输。

The general feature of the plastic deformation is similar in both charging or uncharging hydrogen specimens.

发现：氢的存在并不改变在Ⅰ型或混合型载荷作用下，裂纹尖端的塑性变形特征，即在主裂纹前端，应变呈不对称分布，裂纹尖端Schmid因子决定了条带状局部形变带的轴线方向。

The unetched specimens were instantly observed by QUANTA-400 environment scanning electron microscope,scanning tunnel microscope and optical microscope,respectively.The results show that the surface relief will be found during the bainite transforming and will be in the shape of "Λ".The formation of bainite surface relief is to ...

不经浸蚀，分别采用QUANTA-400环境扫描电镜、Nanofrist-1000扫描隧道显微镜和光学显微镜观察试样，发现，贝氏体相变过程中产生了表面浮凸，表面浮凸为&帐篷形&，并认为贝氏体表面浮凸的产生，是由于过冷奥氏体转变为贝氏体时比体积增大，且试样表面层体积膨胀不均匀造成的。

Now she was hungry and angry.She began to smoulder.

现在她又饿又气，她开始流露难以抑制的怒火。
