当碱性纤维素与盐酸的钠盐反应，羧甲基醚钠盐生成。

Applyingsome inorganic materials, such as sodium silicate, aluminum and potassic sulphate, ferricchloride, sodium aluminate, the author manufactured a new-style JYQ 796 high efficiencyinorganic waterproof and dampproof agent.

针对国际国内各类建筑工程、水利工程、装饰工程等存在着严重的渗水漏水问题，本文以硅酸钠、硫酸铝钾、氯化铁、偏铝酸钠等多种无机原料，成功地研制了一种新型JYQ796型高效无机防水防潮剂，它主要分为无机快速堵漏型(配方4)和高效防水防潮型(配方6)两大类。

Comparing the two kinds of catalyst, although the high conversion could been gotten at the optimum reaction conditions respectively, to the same conversion, the reaction conditions for ammonium molybdate catalyst were higher than that for sodium tungstate catalyst, that means the catalytic activity of ammonium molybdate is higher than that of sodium tungstate.

两种催化剂相比，虽然在最佳工艺条件下，均可使反应达到较高的转化率，但达到相同转化率时钨酸钠催化剂所需的反应条件比钼酸铵催化剂高，所以总体来说，钼酸铵催化剂的反应活性高于钨酸钠催化剂。

Therefore, pretreatment of raw flax was performed with selected chelating agents such as ethylene diamine tetraacetic acid, sodium tripolyphosphate, oxalic acid and ammonium oxalate.

选用EDTA、多聚磷酸钠、草酸和草酸铵等螯合剂对亚麻原麻进行了预处理，结果表明：EDTA、草酸、多聚磷酸钠的处理效果均不理想，改变浓度、温度等条件，韧皮与麻秆并没有分离；而草酸铵是比较有效的螯合剂，用5 g/L的草酸铵在62℃处理亚麻原麻5 h后，韧皮与麻秆能够完全分离。

Objective: To explore clinical significance of serum level of B-type natriuretic peptide in patients with acute coronary syndrome and the effect of atorvastatin on it.

MethodsThe pharmacological effects of the Ziziphus jujube leaf extract on the autonomic activities of mice, the time of sleep induced by pentobarbital sodium, the sleeping synergistic action of mice with barbital sodium at sub-threshold and hypnotic dosages and the central inhibitory effects in mice induced by amphetamine were investigated.

目的观察酸枣叶提取物对中枢神经系统作用。方法考察酸枣叶提取物对小鼠自主活动的影响、对延长戊巴比妥钠诱导的小鼠睡眠时间、对阈下巴比妥钠的睡眠协同作用以及对苯丙胺中枢兴奋作用的影响。

In the process of alumina production by Bayer process, the loss of soda is mainly caused by the formation of sodium hydrate alumino-silicate.

拜耳法生产氧化铝的过程中，碱耗的主要原因是因为有钠硅渣的生成，碱耗可以用赤泥钠硅比表征。

The thermodynamic calculation results indicated that the formation of calcium aluminate hydrate from aluminate solution with CaO is easier than that with Ca2, and the value of αk is great at low temperature; the temperature rise leads to the reduction of stability of calcium aluminate hydrate in the aluminate solution, and it can be decomposed at high temperature, which can both substitute for Ca2 and recover alumina in the process of Bayer.

热力学计算结果表明，氧化钙较氢氧化钙更容易使铝酸钠溶液中的铝酸根离子转化为水合铝酸钙，使铝酸钠溶液的平衡苛性比能达到很高的值；水合铝酸钙随着温度的升高，稳定性降低，因而能在拜尔法高温溶出过程中分解以代替石灰，并回收其中的氧化铝。

Three novel single-singlet energy transfer pairs between ketocoumarin dyes and rose bengal BNa〓 Salt were designed and their properties were studied in micelles and vesicle.

以合成的香豆素染料作为能量给体，以孟加拉玫瑰钠盐作为能量受体，设计了三对新型的能量传递对(即：香豆素染料-孟加拉玫瑰钠盐)，研究了它们在胶束或囊泡中的能量传递，其结果如下
