The improved method selects the absorbing wavelength of 618 nm and the reaction time of 40 min, uses the NH4Cl-NH3 buffer solution (pH=8.0) and BTB alcohol solution (0.4 g/L) respectively of 5 ml and 1.5 ml in the 50 ml volumetric flask, and can test the concentration of imidazolinyl-quaternary-ammonium-salts in range of 0 mg/L to 80 mg/L.

利用改进的显色反应法检测时，吸收波长选择618 nm，显色时间40 min， 5 ml容量瓶中NH4Cl-NH：缓冲液(pH=8.0)和BTB乙醇溶液(0.4 g/L)的添加量分别为 5 ml、15 ml，适用检测的咪唑啉季铵盐浓度为0~80 mg/L。

The paper involved two parts: Part 1: A two-chambered microbial fuel cell was constructed with high-concentration sodium acetate as fuel in the anode. The influence of different electron acceptors in the cathode, external resistance value, pH value and concentration of sodium acetate on electricity generation in MFC was investigated. The result showed that the maximum power density of 294.72 mW/m2 and the coulombic efficiency of 25.87% was achieved at sodium acetate concentration of 6.46 g/L, pH 7.0, external resistance 500Ωin the anode and when using potassium permanganate as electron acceptor in the cathode.

全文分为两个部分：第一部分：以乙酸钠为阳极原料构建双室微生物燃料电池，研究不同阴极受体、外接电阻、乙酸钠浓度和pH等因素对电池产电性能的影响，研究结果表明：在500mL的阴阳极反应体系中，选用乙酸钠作为阳极底物，质量浓度为6.46 g/L， pH 7.0，接入500Ω外电阻，阴极电子受体选择高锰酸钾的情况下，微生物燃料电池产电性能最好，最大电功率密度达到294.72 mW/m2，库伦效率能达到25.87%。

A series of amorphous Ni-Sn-B/SiO 2 catalysts with different tin contents were prepared by salt impregnation and KBH 4 reduction.

采用化学还原法制备了一系列三元非晶态Ni Sn B/SiO2 催化剂，并考察了Sn含量对催化剂的苯乙酮选择加氢制备苯乙醇反应的活性及选择性的影响，同时对Sn改性前后的催化剂进行了系统的表征。

On the other hand, sodium tungstate dehydrate complexed with oxalic acid can act as highly efficient catalysts for the transformation from alcohols to carbonyl compounds under controlled microwave irradiation and solvent-free conditions.

第二部分中，我们观察到，作为一种过程强化手段，微波具有显著的促进催化选择氧化反应加速进行的能力，这在多相的锰氧化合物体系和均相的钨酸钠—草酸催化体系中都有具体表现。

Basing on experimental study, the article analyses the process of calcination and desulfuration reaction and builds a mathematical model of calcium-based materials (limestone, shell and their mixture), which will provide theoretical basis and practical guidance for improved performance of the normal sulfur sorbent and the choice of new sulfur sorbent.

然而传统的燃煤固硫剂石灰石，因钙转化率低而使该技术的推广应用受到限制，在实验研究的基础上，对钙基材料—石灰石和贝壳用于燃煤的煅烧固硫反应过程进行数学建模与分析，以便为改善常规固硫剂的性能，选择新型固硫剂提供理论依据和实用指导。

Most of the studies linking allergies to joint disease have focused on rheumatoid arthritis , although mention of what was called "rheumatism" in older reports suggests a possible link between food reactions and aggravations of OA symptoms. 4 If other therapies are unsuccessful in relieving symptoms, people with OA might choose to discuss food allergy identification and elimination with a physician.

连接过敏的关节疾病的研究大多集中在类风湿关节炎，尽管什么是所谓的&风湿较旧的报告&提到的建议反应之间的食物和关节炎症状加重处罚可能存在的联系。4如果其他疗法缓解症状不太成功，关节炎的人可能会选择与医生讨论食物过敏识别和消除。

This initial discovery stage will give you the opportunity to react to incompatibilities and move on to your next choice without a significant hit to resources.

这个最初的发现将让你有机会作出不兼容的反应，你的下一个选择并不会使资源有重大的打击。

Unlike Pavlov's dogs or other animals who respond only by instinct, we humans have the power of choice.

不像仅靠本能作出反应的巴甫洛夫（通过狗的实验研究了条件发射）的狗或其它动物，我们人类拥有选择的能力。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
