硼酸甘油

The factors such as boric acid concentration and pH,influencing formation of complex of HPMC and glucose were studied.

研究了硼酸浓度和pH值对葡萄糖-羟丙基甲基纤维素体系分离性能的影响；并将葡萄糖与其它添加剂如甘油、甘露醇对分离的影响作了比较，葡萄糖特有的环状结构使得其对羟丙基甲基纤维素体系分离能力的提高更为显著。

The M11 paint developed by Masteel is a semi-organic material,mainly composed of acrylic resin emulsion,zinc dichromate solution,boric acid and glycerol.It can be applied in the high speed roll coating of electrical steels made by continuous annealing lines.The interlamination resistance of M11 chromate-containing insulating coating is above 150 Ω·mm2 per piece...

并对其性能进行了检测分析，结果表明，M11含铬绝缘涂料是一种主要由丙烯酸树脂乳液、重铬酸锌水溶液、硼酸、甘油等组成的半有机涂料，其性能满足电工钢连续退火生产线高速辊涂的需要；通过涂层工艺的合理控制，M11含铬绝缘涂层，其层间电阻在150Ω。mm2/片以上，综合性能满足电工钢用户的需要。

Starting with boric acid and glycerin, several organoboron based surfactants using diglycerin borate as intermediate and modified with epoxyethane were synthesized.

以硼酸和甘油为起始原料，合成了几种以硼酸双甘油酯为中间体及环氧乙烷修饰的有机硼表面活性剂。

Some additives that could enhance the enzyme stability were screened through single factor experiments, such as 5 mmolL^(-1) Ca(superscript 2+), 20 mgmL^(-1) trimethylene glycol-single methyl ether, 0.01% 4-formyl phenyl-boron dihydroxide, 1% glycerine.

通过单因素实验得出了对碱性蛋白酶稳定效果较好的几种保护剂：5mmolL^(-1) Ca(上标 2+)；20mgmL^(-1)微胶粒抑制剂丙二醇－单甲醚；0.01%可逆蛋白酶活性抑制剂4－甲酰苯基硼酸；1%甘油。

The different enzyme protecting agent had effected on the liquid alkaline protease under the dissimilar condition. Taking the living rate of enzyme as the target, we obtained one high effective alkaline protease stabilizing agent formula through orthogonal experiments as following: 5 mmolL^(-1) Ca(superscript 2+), 15mgmL^(-1) trimethylene glycol-single methyl ether, 0.015% 4-formyl phenyl-boron dihydroxide, 1% glycerine.

在此基础上，进行L13(3^7)正交实验，以相对酶活率为指标，考察了不同酶活性保护剂在不同条件下对液体碱性蛋白酶活力的影响，筛选到一种优质高效的碱性蛋白酶稳定剂配方为：5mmolL^(-1) Ca(上标 2+)，15mgmL^(-1)丙二醇－单甲醚，0.015% 4-甲酰苯基硼酸，1%甘油。

The N-butyl pyridine tetrafluoroborate (BF4) ionic liquid was synthesized, which was used to prepare the phenyl glycidyl ether as solvent and catalyst.

合成了N-正丁基吡啶氟硼酸盐(BF4)离子液体，并将BF4作为溶剂和催化剂用于苯基缩水甘油醚的合成反应。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
