查询词典 semipolar

Result: There were many semipolar, low-polar and nonpolar antimicrobic components in natural products, they diffused slowly in medium, it was possible for false negative and leaked screening by inhibition zone size judging only, but TTC method was better precise and reliable with the sum of indicator size without dyed by TIC and inhibition zone size.

结果：天然产物中存在中极性、弱极性甚至非极性抗菌成分，在培养基中扩散较慢，现行K-B法以透明抑菌圈为判读抗菌活性依据，会低估样品抗菌活性，甚至出现假阴性结果，造成漏筛。以不能被TTC显色的指示菌范围和透明抑菌圈之和来判读天然产物抗菌活性，提高了K-B法检测天然抗菌成分的准确性和可靠性。

PMU extracts containing a mixture of conjugated oestrogen are obtained by means of solid phase extraction on semipolar adsorption resins.

从PMU中获得含有结合型雌激素混合物的提取物可以通过在半极性吸附树脂上的固相提取来进行。

The lowest surface tension of N_xB solution was better at 25℃, and lowest surface tension would down with carbon . cmc( critical micelle concentration) and γ_ in N_(12)B are 4.1 × 10~(-4)mol/L, 24.5 mN.m~(-1),what was smaller than LAS . The cmc of N_(12)B- NaCl are down with NaCl up.The surface tension and cmc of N_(12)B and N_(16)B are higher than that of N_(12)OB and N_(16)OB because of hydrophilic group ,but that of N_(12)B is lower than that of N_(16)B because of hydrophobic group .5. The borate structure and semipolar bond were studied in different pH by infrared spectrum .It indicated that N_xB and N_xOB have not semipolar bond at pH

4、25℃，N_xB系列都有较低的表面张力，并随碳原子数的增加而最低表面张力下降。N_(12)B比同碳原子数的十二烷基苯磺酸钠的最低表面张力34.5mN／m低，且临界胶束浓度为4.1×10~(-5)mol／L，也比LAS低，且随着NaCl浓度的增加而略有下降，比较N_(12)B和N_(16)B，由于C_(16)疏水基的异构体使N_(12)B的临界胶束浓度和临界胶束浓度时的表面张力γ_(cmc都低，由于增加了亲水基团使得N_(12)OB和N_(16)OB的表面张力和临界胶束浓度都要高于N_(12)B和N_(16)B。

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。
