在氯化苄与甲酸钠的酯化反应同时存在甲酸苄酯的水解反应，并且甲酸苄酯的水解反应是可逆反应，受化学平衡的限制，在实验条件下的甲酸苄酯与苯甲醇平衡的摩尔比大致为3：7。

In the present paper, a study on absorption and utilization of inorganic carbon of Spirulina platens is and the relationship between the concentration of inorganic carbon and its growth was carried out.

文中报道了螺旋藻对无机碳的吸收利用以及与其生长的关系，结果表明螺旋藻培养基中碳酸氢钠的浓度50～100mm ol/dm3时，不仅可以满足螺旋藻生长的需要，而且有助于保持藻体生长的pH值。

na2samg:zinc was combined with sodium sulphide perfusion; znseamg:zinc was combined with injection sodium selenite in advanced;iznsamg:the animal's fresh tissue immersed in the timm's immersion fluid. aboved three methods were followed by the same amg method.

ivznsamg：采用na2s溶液灌流的锌离子结合方式；znseamg：采用事先注射硒酸钠的体内锌离子结合方式；iznsamg：采用取动物新鲜组织浸泡在浸染液中的锌离子结合方式；以上三种方法处理后均采用相同的amg孵育显色。tsq、zinquin荧光：均为新鲜组织取材，液氮处理后荧光下观察。

Allowable current density is firstly confirmed by analyzing the variation of current efficiency with current density. Effects of content of ammonia ions, pH value and the content of sodium formate upon the throwing power, covering power and ability of anti-impurities, were measured.

首先通过分析电流效率随电流密度的变化情况确定了镀液的许用电流密度，然后测定了氨的含量、镀液pH值、甲酸钠的含量等因素对分散能力、深镀能力、抗杂性能等镀液性能的影响。

The epoxidation can be performedwell when the concentration of quaternary ammoniumsaltand sodium tungstate is 0.06 mol/L and 0.03 mol/L, respectively.

结果表明，季铵盐和钨酸钠的浓度分别为0.06，0.03 mol/L时的催化效果最佳；α-和β-蒎烯的转化率随着H2O2与蒎烯的量比增大而增大，当H2O2与α-蒎烯和β-蒎烯的量比分别为2.0和1.8时，其转化率均可达到100%；较高的温度不利于环氧化反应的进行，因此，环氧化反应温度需控制在20℃以下。

In order to extend use of calcium carbonate, the samples were modified by hydrazine hydrate, triethanolamine and sodium stearate. Hydrazine hydrate was 0.08%～0.24% of calcium oxide, triethanolamine was 0.1%～0.3% of calcium oxide, sodium stearate was 5% of calcium carbonate,modification time was 40 minute. Calcium carbonate has better active exponent and white degree.

为进一步扩大纳米碳酸钙的应用范围，对纳米碳酸钙进行了增白活化的改性，改性剂水合肼、三乙醇胺的用量分别取CaO质量的0.08%～0.24%、0.1%～0.3%，硬脂酸钠的用量取CaCO3质量的5%，改性时间为40min，在此条件下可以制得高白度、高活性的碳酸钙样品。

The main factors that affect the analyse results, such as the acidity, the amount of sodium acetate anhydrous and ammonium persulfate etc. were investigated in detail.
