The ceramic mud of concentration of 40%-60% are measured, the measured voltage and its corresponding ceramic mud's argil content relationship was analyzed, it is liner for ceramic mud of concentration between 40%-60%.

分别检测浓度为40%-60%的陶瓷泥浆样本，记录、分析这组电压值和陶瓷泥浆浓度的关系后知道：在陶土含量为40%-60%之间的数据曲线是线性的。

The results show that the oxidation process of arsenopyrite is speeded up with increasing concentration of FeCl3solution and rising temperature of reaction within the temperature range of 15~35℃, whereas the reaction rate of arsenopyrite is reduced at 45℃, and that the arsenic released from the reaction of arsenopyrite with FeCl3acidic solutions whose concentration is lower than 1×10-4mol·kg-1is in the form of As, which is likely to be soon oxidized into As in the FeCl3acidic solution.

结果显示：在温度为 15~35℃内，毒砂的氧化随FeCl3溶液浓度增加和反应温度升高而加速，而45℃时毒砂的反应速率反而降低；毒砂在与氧化剂FeCl3酸性溶液(浓度小于1×10-4mol·kg-1)反应时释放到溶液中的砷为As，As在FeCl3酸性溶液中很快被氧化成As。

Consequently, the properties of asphaltene film will change, but the properties of resin films have been rarely affected.

胶质在此浓度范围没有象沥青质这种自缔合现象，胶质膜的表面浓度几乎不受这些因素的影响。

(1) to deliver the Levonorgestrel (0.ml/kg,5mg/m) and Mifepristone gelatum (0.1ml/kg,5mg/ml) per cutem to the rat respectively and measure the serum concentration of levonorgestrel、mifepristone、estradiol and progesterone at different time by the means of HPLC, radioimmunoassay,chemical separation and atomic absorption spectrophotome.

大鼠皮肤涂抹米非司酮凝胶(0.1ml/kg，5mg/ml)和左炔诺孕酮凝胶(0.1ml/kg，1mg/ml)后的不同时间，利用高效液相色谱法、放射免疫分析法、化学分离与原子吸收分光光度法，测量血清中米非司酮浓度、左炔诺孕酮凝胶以及血清雌二醇、孕酮浓度。

Compared to wet season, arsenic is difficult to mobile in dry season. Attenuation constant in dry season is 0.3082(1/km), but it is 0.0569(1/km)in wet season. If initial concentration of As was 500μg/L without other contamination source in down stream, arsenic would deceased to 50μg/L in down stream 7.5km in dry season but 40km in down stream 40km. As is dominate species in river running throμgh mining area.

砷在枯水期较丰水期难以迁移，通过计算得到，在枯水期砷的衰减系数K值为0.3082(1/km)，而在丰水期为0.0569(1/km)；在污染口浓度达到500μg/L时，下游没有其它的砷的污染源(或会影响砷衰减的其它污染源)时，枯水期砷会在下游7.5km之后浓度降到50μg/L，而丰水期则要在下游40km之后才能降到同样的值，所以在丰水期砷污染的影响的流域更广。

The effects of the initial NH+4-N, DO and pH on the completely autotrophic nitrogen removal performance of the granular sludge were investigated in batch experiments.

采用间歇实验，考察了初始NH+4-N浓度、DO浓度和pH对颗粒污泥完全自营养脱氮的特性的影响。

Methods: Separated 120 cases with glomerular diseases into chronic glomerular nephritis group (70 cases, including 33 cases with normal serum creatinine, 17 cases with azotemia, 20 cases with uremia, 33 cases accompanied with hypertension), acute nephritis group (12 cases), nephritic syndrome group (38 cases), and selected 30 healthy cases as control group. Detected concentration of NO in serum with nitrate reductase method, and made comparison among groups.

120例肾小球疾病患者分为慢性肾小球肾炎组（70例，其中血清肌酐正常33例，氮质血症17例，尿毒症20例，伴有高血压33例）、急性肾炎组（12例）、肾病综合征组（38例），同期选择30例健康体检者作为对照组，采用稍酸还原酶法测定肾小球疾病患者及对照组血浆NO浓度，并对各组NO浓度进行比较。

Moreover, the stimulative effect on organic phosphobacteria was greater than azotobacter, and the inhibitory effect on inorganic phosphobacteria was greater than potassiumbacteria.

同时，由于抗性微生物的出现，在大部分时间点，克百威对四种微生物的影响并不随其浓度的增大而增强，即微生物数量与克百威浓度的相关性很小或基本不存在相关关系。

Using 192 lines from BC2F2 backcross population and their equivalent progeny BC2F3, fine mapping of SKC1 was performed.

SKC1是一个控制盐胁迫下水稻地上部K+浓度的主效QTL，它可以解释40.1%的K+浓度表型变异。

Ethanol is more effective at a concentration of 50-70 per cent, below 20 per cent, its bactericidal action is negligible.

乙醇的浓度为50%-70%时比较有效，浓度低于20%时，杀菌能力基本上就不存在了。

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.

要是在劳改农场，你等着挨绳子吧！
