A method for determination of mercury in blood using a thiourea mixed extraction method has been ...

本文针对常规分析方法存在的不足，研究建立了硫脲混合液提取测定血样中汞的新方法，样品预处理不需要加热消解，且由于硫脲混合液与汞生成稳定化合物，可有效地减少常规预处理方法在样品预处理和测定过程中汞的吸附和挥发损失，方法的回收率高、重现性好、简便、快速、分析费用低。

The epidemiological investigation of the field suggested that there may have an infectious virus unit at least, in 96L air by threshing machine and 350L air by the nest of A. agrarius , respectively.

对现场采集的空气样品和收集的打谷者佩戴的口罩样品的研究发现，在稻田堆放的稻捆根部和鼠栖息的草窝的空气中每 35 0L空气中和打谷场脱粒机附近每 96L空气中，含有至少一个具有生物活性的汉坦病毒粒子。

The time interval between the melting of the 20‰ standard and the 5 standard was about 25 minutes.

样品20‰和样品5‰的溶化的时间间隔大约是25分钟。

It is found that rate of TL is smaller than that of TN and TK.

研究表明，含Li离子的样品相对于含Na离子和K离子的样品来说其粘度变化速率较小。

Electrical resistivity was studied by Van der Pauw method and samples with which around 10·cm deposited at oxygen partial pressure of 30%, ToFF=30s and 50%, ToFF=40s, respectively, are suit for our further study.

利用范德堡法研究了样品的电阻率，在氧分压为30%，Toff=30s和50%，Toff=40s下制备的样品的电阻率为10·cm左右。

We would charge trinal sampling fees, but if you place the PO in the future/in coming day, the fees would be deducted ...

我们需先收3倍的样品费，但是如果您有下单，可以在大货中扣除这部分样品费用。

We would charge trinal sampling fees, but if you place the PO in the future/in coming day, the fees would be deducted from the order amount.

我们需先收3倍的样品费，但是如果您有下单，可以在大货中扣除这部分样品费用。

At the same time, people have made progress in measurement method of tritium. It is different in the measurement instrument and the chemical agents and the compositions of the sample.

由于测量的仪器、所用的化学试剂及所测样品的组成各不相同，对某一特定工艺条件下的各种氚样品的测量方法作有针对性的研究，这对分析测定的质量保证仍是十分必要的。

It obtains the various optical images of the sample's nanometer surface, transcended the diffraction limit of conventional optical microscope, by using a fine optical-fiber tip probing ultra-high frequency optical information on the sample surface. And it has extensively been applied on life science, chemistry and material science fields.

它利用细小的光学探针探测样品表面隐失波的超高频空间信息，超越经典衍射极限的限制，可对样品表面纳米尺度区域的各种光学信息进行扫描成像，在生命科学、化学及材料科学领域中都有着广泛而重要的应用。

The colloidal material concentration is calculated by using integral sample concentrations of ultrafiltrate and retention with concentrate factors

实际分析样品时，应选择合适的浓缩因子，固定的膜压及流速对样品进行分离，胶体物质浓度应用超滤结束后超滤液和浓缩液中的物质浓度结合浓缩因子进行计算。

She gently rebuff ed him, but agreed that they could be friends

她婉言拒绝了，但同意作为朋友相处。

If in the penal farm, you were sure to be criticized.
