This paper presents the experimental data of metastable phase equilibrium of Li~+/Cl~-,CO_3~(2-),B_4O_7~(2-)-H_2O quaternary system at 298 K for Zhabuye salt lake in Tibet,from which the metastable phase diagram and physicochechemical properties(density,pH value,conductivity and refractive index) vs composition diagram is drawn.
根据对西藏扎布耶盐湖四元子体系L i+/C l-,CO32-,B4O72--H2O 298 K介稳平衡实验数据,绘制出的介稳平衡相图及物化性质(密度、pH值、电导率、折光率)组成图的研究结果表明:该四元体系属简单共饱型,无复盐或固溶体形成;其溶解度等温图含有一个共饱点、3条单变量曲线和3个结晶相区;3个结晶相区分别对应为L i2B4O7。
Some theorems about modulus of continuity were obtained by discussing the Bernstein polynomial.

在自制的结晶器内,根据CaCO3结晶介稳区理论,利用临界pH法考察阻垢剂ATMP浓度与循环冷却水中Ca2+浓度的临界关系,得到45℃、pH=9的条件下阻垢剂ATMP最低用量的估算公式,并对此公式用模拟循环冷却水进行了验证。
The metastable regions of glutamic acid solutions in ethanol-water solvents were wider than that in pure water,so that it can be probably hoped to improve the condition of crystal growth.
