The optimal time for combination of radiosensitizers and radiotherapy will be determined from the significant difference of uptake and retention between the tumor and the major normal tissues. The biodistribution obtained from organ removal and counted by gamma scintillation counter was similar to that obtained from autoradiography.

本研究利用加马闪烁计数器与自动放射摄影术两种方法，探讨分别或同时使用[131I] IUdR、[18F] FMISO在肿瘤及正常器官的摄取状况、清除速率及生物分布，找出此两种药物在肿瘤中积聚最多的时间点，并与其他正常器官有明显的差别，以期应用在临床上病人给药的依据。

Mutans was purified from recombinant bacteria. GtfD was incubated in buffered-KCl solution with dextran and sucrose containing sucrose-［14C-glucose ］. The bound activity of GtfD was measured with a scintillation counter. The effects of peroxidase system and its components on the activity of GtfD were examined by incubating different components separately and together with GtfD.

变链菌GtfD由重组菌提纯， GtfD与含葡聚糖和蔗糖（含C14标记葡萄糖）的氯化钾缓冲液孵育，经闪烁计数器测定GtfD活性；过氧化物酶系统及其组份对GtfD活性的影响，通过将这些组份单独或共同和GtfD孵育得以测定。

The metal sample is dissolved with HCl H 2O 2, and the dissolved nickel is separated from other activation products by anion exchange. Nickel is then complexed with pealetyldioxime in the alkaline solution, extracted with toluene, and finally determined by liquid scintillation counter.

先将样品用HCl H2 O2 溶液溶解、再经阴离子交换、氢氧化物沉淀分离后，在碱性溶液中用丁二酮肟配合镍、甲苯萃取、稀HCl反萃后再用液体闪烁计数器测定反萃液中6 3Ni放射性活度、原子吸收分光光度计测定金属中稳定镍。

For example, a frame counter component or even a fullblown 3D landscape rendering engine could be implemented as a game component, but just because someone does not use a game component does not mean it is harder to copy over.

例如，一个帧计数器组件或者甚至是一个完善的3D 风景渲染引擎都可以作为一个组件运行，但是并不是说某人不使用组件游戏就变得困难。
