The energy of excited state depended on the nature of different cations. 3. 4-(4-tolyl)-6-phenyl-2, 2'-bipyridine platinum acetylide complex containing a monoazazcrown moiety in the acetylide ligand could signal Mg〓 specifically and displayed large changes both in color and in luminescence intensity upon complexation with Mg〓. The most striking result was that it could signal Mg〓 specifically even in the presence of alkali and alkaline earth metal ions in high concentrations.

对位带有氮杂-15-冠-5冠醚的苯乙炔为辅助配体的4-（4-甲基苯基）-6-苯基-2，2'-联吡啶Pt络合物AC，不仅在碱金属和碱土金属的存在下吸收光谱明显改变，更有意义的是，它只有在Mg〓离子存在时能够发光，因此可以通过发射光谱选择性的识别Mg〓，尤其可以在高浓度的其它金属离子存在下选择性的检出Mg〓离子。

Results The reference range of serum Cys C in healthy people was ≤1.02 mg/L in our laboratory. The correlation coefficient between Cr and Cys C was 0.734 6. The serum level of Cys C in patient with DM was higher than that in healthy people. The level of Cys C in 2.18-3.15 mg/L and ≥3.16 mg/L could be defined as the limits of azotemia and uremia.

结果 本实验室健康人群Cys C参考范围为≤1.02 mg/L，Cys C与Cr的相关系数为0.734 6，Cys C水平在2.18~3.15 mg/L和≥3.16 mg/L可分别作为界定肾功能不全氮质血症期和尿毒症期的衡量标准，糖尿病患者的Cys C水平明显高于一般人群。

Involucrata Bailt, younger than 5 -year old, used as explants were inoculated in improved MS medium after ring-barking and 25 treatments for improved MS mediums adding 0,0.1,0.2,0.3,0.4 mg/L NAA, 0,10,20,30,40 mg/L bean sprout juice and 0, 5, 10, 15, 20 mg/L tomato juice respectively were set up to select the optimum medium.

方法采集5年生以下珙桐的嫩枝条幼嫩茎为外植体，环割后接种在改良MS培养基上，培养基设25个处理，分别添加浓度为0、0.1、0.2、0.3、0.4 mg/L的NAA，浓度为0、10、20、30、40 mg/L的豆芽汁和浓度为0、5、10、15、20 mg/L的番茄汁。

Result］ The new buds and petals of I.germanica was proper to be used as explant of tissue culture, with lower browning rate compared with other positions. The well situated tissue block of explant (3 mm×3 mm×3 mm) might reduce browning rate. Adding 0.1%Vc or 0.3% active carbon in medium had obvious effect on preventing tissue browning. The exogenous hormone 2 mg/L 6-BA was easy to lead to brownness turning, and 2 mg/L Kt and 2 mg/L NAA brought less effect to tissue browning. When using disinfectants of alcohol, its dipping time of 5～10 s for explant was the best, with the minimum browning rate. The culture under full illumination condition was liable to induce brownness turning, compared with other cultured conditions, the brownness turning could be restrained effectively by using imitating artificial climate condition for culture.

结果］ 鸢尾的新生芽和花瓣较适宜作组织培养的外植体，与其他部位相比褐变率较低；外植体组织块适中（3 mm×3 mm×3 mm）可降低褐变率；在培养基中加入0.1%Vc或0.3%活性炭对防止组织褐化效果明显；外源激素2 mg/L 6-BA易引发褐变，2 mg/L Kt和2 mg/L NAA对组织褐变影响不大；使用乙醇消毒剂时，对外植体浸泡时间以5～10 s为佳，褐变率最低；全光照条件培养容易诱发褐变，采用仿人工气候条件培养较其他条件培养可有效抑制褐变的发生。

But when Fe/D113 precursor is pyrolysed in the range of 400-700℃, the crystal structure of the iron particle is different. The products are mainly iron oxides andα-Fe as Fe/D113 precursor pyrolysed at 500℃, and as the pyrolytic temperature increases to the range of 600-700℃,α-Fe and Fe_3C are observed. Meanwhile, Al_2O_3、MgO、MgAl_2O_4 were observed in Al/C, Mg/C, Al-Mg/C which were prepared from D113 resin at 1000-1300℃.

Results showed that low contents of Cd has promotion effect on Oryza Sativa, but high contents of Cd has not obvious restrain on it. The total trend of distribution of Cd in Oryza Sativa is root＞stem＞shell＞rice. The relation between Cd contents in rice and total Cd in soil as well as availability Cd in soil has been investigated. The result showed that both the total Cd and the availability Cd had notably correlation with content of Cd to rice, and the critical point were CaCl2-Cd=0.71mg/kg, DTPA-Cd=1.34 mg/kg, EDTA-Cd=0.76 mg/kg, NH4OAc-Cd=0.77 mg/kg.
