查询词典 hydrogen ion

The osmotic coefficients and saturated vapor pressures have been calculated at the different temperatures .The experimental values of the osmotic coefficients for the Li_2SO_4-H_2O system were consistent with the values in the references. The results revealed the rules of the changing in osmotic coefficients and saturated vapor pressures with ion strengths and the molality fractions of Li_2B_4O_7 at different temperatures. The isopiestic equilibrium molalities were correlated by using the modified and the extended Zdanovskii rules for non-ideal mixtures, and obey well the Zdanovskii rules. The ion interaction parameters of Pitzer model have been determined by using the two methods for Li_2SO_4-Li_2B_4O_7-H_2O at 298.15K system.

The results indicate that the amount of chloride ion sedimentation is attenuated by the natural logarithm function of distance from external surface of the sample,and the corresponding attenuation rate is changed greatly by the ratio of water to cement and mineral admixture such as slag. Chloride ion is mainly deposited in surface zone under dry-wet cycle condition.

一般来说，正离子对我们人体是有害的，负离子则相反。

Because the function of negative ion is able to balance the bad affection of positive ion.

在二十世纪的初期，负离子在大气层中的比例为二比一，不过根据最近的研究报告指出，目前该比例已经完全相反，成为一比二的严重情况。

At the locations of residential area in Tokyo, Japan; the strength of positive ion is 500 times more then negative ion.

在日本东京的住宅区，其正离子强度是负离子值的500倍以上。

Toshiba developed the lithium ion battery unit which could charge rapidly, besides the characteristics of small, large capacity, it used fixed technology which was able to cause the nanometer level particle homogenizing, might cause the lithium ion be adsorbed evenly on the negative terminal of the battery, could charged to 80% of its capacity in one minute, 6 minutes more was possible to fill the electricity.

您可以鹬第二和第三工会领袖从这一立场出发。

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.
