所建方法简便、灵敏、准确，可用于辅酶Q10的含量测定及有关物质的检查。

PbWO4 and CeF3 which are newly developed inorganic scinti1latr in our country have been studied. Photo-electricity detector systemes which have high γ sensitivity and relative insensitive to neutron and fast time response were assembled by using CeF3 and photomultiplier tube. The ratio of signal-to-noise for γ ray detection can be up to more than 10 times in close distance n,γ commix pulse radiation field by using this detector system.

对PbWO4和CeF3等近年国内新研制的无机闪烁体进行了系列研究，使用CeF3分别配光电倍增管和光电管，组合出了对γ辐射灵敏度高，对中子相对不灵敏，同时脉冲响应也快的光电探测系统，应用以此为基础的探测技术在近距离n，γ混合脉冲辐射场中，可将脉冲γ辐射探测信噪比提高一个量级以上。

The letterpress adopts the suitable solid reagent to take the place of the liquid sour and the organic reagent in the Diphenylcarbazide hydrazine intensity of light method (GB7467-87) to mensurate. hexavalent chromium in water.. It has carried out the rapid mensuration of chromium in water using entire solid commixture reagent and it selects affecting condions of the mensuration and maks the optimization .

为应对突发性水污染事故的现场应急监测， 2006年我中心购置的美国哈希便携式DR/2400型多参数仪，该设备适用于地表水和地下水等环境水中铬的测定，是一种准确、灵敏、快速、简便的测定仪，在2006年陕西镇安5-30水污染事故的应急监测中发挥的极其重要的作用，但由于该仪器所使用的试剂是专用的试剂，其价格昂贵、购置麻烦。

The shaped pulses were shown to be phase-sensitive at intensities too low to access different higher electronic states, and so these pulses apparently steer the isomerization through constructive and destructive interference effects, a mechanism supported by observed signatures of vibrational coherence.

脉冲形状被证明是在太低以至于不能进入不同的较高电子态的强度上对相位变化灵敏的，因此这些脉冲机制通过构成和破坏干扰反应操纵着异构化作用，这种机制由观测到的相干信号支持。

The Kepler missionis similar to COROT , but will be more sensitive. Moreover, it will beplaced in an orbit better suited to locating its quarry.

开普勒探测器与 COROT 卫星相类似，但会更灵敏；再者，它的运行轨道将更有利于锁定"猎物"。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
