solut

Each group is made up of 20 hives . The time for all the solut - ion 's entering ( indicating current velocity ) are 3 minutes ) 10 15 minutes and 12 20 minutes respectively .

20箱蜜蜂为一组，溶液全部进入饲喂器的时间，水为3分钟，60%的糖浆10～15分钟，67%的糖浆12～20分钟。

It is shown by test results that the concentration of weak corrosion solut ion , current density and conduction time have the effects to coating corrosion resistance , using a proper weak corrosion technology can improve the corrosion resistance of hard chromium coating .

结果表明，弱腐蚀溶液浓度、电流密度和通电时间对镀层耐腐蚀性能均有影响，采用适当的弱腐蚀工艺可提高硬铬层的耐腐蚀性能。

Solut ion Temperature Control Method Based on Pattern Recognition

在模式识别下的萃取液温度控制方法研究

The composites of CaCO 3 and calc iu m stearate were synthesized by co-precipitation method in sodium stearate solut ion .

以硬脂酸钠盐皂化液为介质，共沉淀法合成碳酸钙/硬脂酸钙复合物。

Because of the method can solut not only strength of construction , but also the stiffness of construction . So , it has become an aided design means for the metallurgical equipment or the machine equipment .

由于该方法不仅可以解决结构强度问题，也可以解决刚度问题，所以已经成为冶金设备或其它机械设备的辅助设计手段。

Under comparably weaker conditions , the corresponding functional is proved to satisfy the Cerami condition . Moreover , by using the Fountain theorem of Bartsch , the existence of infinitely many solut ons with large energy for the equations are obtained .

在较弱的条件下，证明方程所对应的泛函满足Cerami条件，进而应用Bartsch的喷泉定理，得到了方程无穷多个大能量解的存在性。
