Objective To explore the clinical value of renal dynamic imaging and urinary N-acetyl-β-D-glucosaminidase, apoplosis DNA fragment in evaluating the damage degree of hydronephrotic kidneys in children with hydronephrosis.

目的 探讨核素肾动态显像单光子发射计算机断层扫描仪检查与肾盂尿N-乙酰－β-D-氨基葡萄糖苷酶、凋亡DNA片段水平检测在评定肾积水患儿病肾损害中的临床价值。

Low γ ray with 59.6keV energy acts as excitation for rare earth inaqueous and organic phase samples in separation processes by solvent extraction. As aresult, characteristic K series X-ray fluorescence of rare earths emitted. X-ray wasdetected by high purity planar Ge after transmitting Be window. The signals wereamplified by pre-amplifier or main amplifier, and the amulated signals are converted todigital ones.

对溶剂萃取法生产稀土流程中的有机相和水相试样，采用放射性核素〓的59.6keV单色能量激发稀土元素，得到特征K系X射线荧光，透过Be窗经高纯平面锗半导体探测器检测其强度，再经放大器、模数转换和多道缓冲存诸记录试样的能谱。

Gated ~(99)Tc~m-hexakis-2-methoxy-isobutyl isonitrile /~(18)F-fluorodeoxyglucose single photon emission tomography with dual isotope simultaneous acquisition can provide the information about left ventricular function, myocardial perfusion and metabolism simultaneously.

~(99)Tc~m-甲氧基异丁基异腈和~(18)F-脱氧葡萄糖双核素同时采集单光子计算机断层显像可以一次显像获得左心室心肌的血流灌注和葡萄糖代谢的情况，如果加上门控采集，可以同时了解左心室功能的信息。

ABSTRACT Gated 〓Tc〓-hexakis-2-methoxy-isobutyl isonitrile /〓F-fluorodeoxyglucose single photon emission tomography with dual isotope simultaneous acquisition can provide the information about left ventricular function, myocardial perfusion and metabolism simultaneously.

Tc〓-甲氧基异丁基异腈和〓F-脱氧葡萄糖双核素同时采集单光子计算机断层显像可以一次显像获得左心室心肌的血流灌注和葡萄糖代谢的情况，如果加上门控采集，可以同时了解左心室功能的信息。

The contributions of photon radiations are ignored because they are negligible compared to the contributions of the particle radiations, or can be calculated and added to the S-values using MIRD formulae.

如果细胞群较小，则光子的剂量贡献忽略不记。细胞群中每个细胞内的放射性活度相同。计算得到细胞群中各个周围细胞中心到靶细胞中心的距离和周围细胞中的核素对靶细胞的剂量贡献。

While compared with routine linearity injection, arc-needle injection 131I-iodinated oil step-by-step sector-shapely through implant C6 glioma and SMMC-7721 hepatoma at subcutis, Rat survival time increased, the body weight kept less descent, their lumps necrose wholely.

对C6、中文提要放射性核素在瘤体内的均匀弥散、持续滞留和辐射剂量估算研究 sMMc一7721的皮下瘤模型瘤内弧形针分段扇形注射'3，I一碘化油，与直行针线状注射相比，动物存活时间长，体重下降少，肿块皇整体坏死。

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。

Go down on one's knees;kneel down

屈膝跪下。。。下跪祈祷
