Study and Application of Electrochemical Behavior of Calcium-ARS on a Mercury Film Electrode
      
A sensitive complex absorptive wave of Ca-ARS was obtained by using differential pulse voltammetry when a mercury film glass carbon electrode was immersed in 0.1 mol L-1 KOH and 4.5×10-4 mol L-1 ARS solution.
      
The content of the total mercury in various dissolutions of cinnabar was analyzed by UV/VIS Spectrophotometer.
      
It is postulated that cinnabar could be dissolved in the gastrointestinal tract in various forms of sulfur-containing mercury complexes.
      
The 185 nm vacuum UV (VUV) intensity of the MWUVL amounted to 12% of the total UV output, about 1.7 times as high as that of the con ventional low-pressure mercury lamp.

Nevertheless, Hg2+ can inhibit activity of aquaporins, and and LP of roots decreased 22% in distilled water and 68% in NH4NO3 solution after treatment by HgCl2 respectively.
      
These evidences suggested that both Hg2+-sensitive aquaporins and ion channels existing in the protoplasm and vacuole membranes could regulate root water uptake, transport, and integral plant water balance.
      
Drinking water samples of patients with endemic arsenism and a control group were examined using hydride generation atomic fluorescence spectrometry (HG-AFS).
      
A density functional theory study of the adsorption of Hg and HgCl2 on a CaO(001) surface
      
When the mercury chloride molecular axis is parallel to the surface, the Hg atom coordinates to the O2- anion and has a binding energy of 87.829 kJ/mol, which means that the parallel geometry is more stable than the vertical one.

An interference pattern of two systems of fringes has been obtained by vising two radiations in a Hilger prism interferometer A system of white bands with equal spacing which are always parallel to the refracting, edge of the prisin is the result of the intersection of the two systems of fringes. The white bauds travel as one of the reflecting mirror in the interferometer makes a parallel displacement. Let d be the displacement of mirror when the white bauds travel one spacing,Two yellow doublets in sodium and mercury lamps were used. The values found forA comparison of this method with the visibility corve by Michelson interfero-ineter has been discussed.

在Hilger棱镜干涉仪中,用两辐射线,则在一干涉图形中可得两组不同方向之干涉纹;因两组不同方向之干涉纹之相交,而得一组平行之白色条纹。此种条纹恒与棱镜折射边相平行,而条纹间之间隔为相等。当干涉仪之一反射镜作前後平行移动时,白色条纹则向左或右移动。令白色条纹移过一间隔时,反射镜移动之距离为d.则得 1/(λ_2)-1/(λ_1)=1/2d. 钠光及光灯中之黄色双线普用于此实验中。1/(λ_2)-1/(λ_1)之值各求得为17.22厘米~(-1)及63.29厘米~(-1)。此实验与麦凯尔逊干涉仪之明视曲线互见短长,本文曾讨论及之。

Vanillalrhodanine was found to be an excellent reagent for silver ions. Its 0.2 percent solution in acetone gives a brownish violet precipitate with silver ions in ammoniacal solution. Limit of identification: 0.01γ. Concen- tration limit: 1∶5,000,000. Merecric and merourous ions give same reactions, but they can be removed by the addition of aqueous ammonia and the test is to be carried out in the filtrate. Ferric ions, when present in high concentra- tions, interfere the observation of silver.

3甲氧基4羥基亞苄羅丹寧可以用作銀離子的斑點試劑。其千分之二丙酮溶液與銀離子在含氨溶液中生成棕紫色沈澱。鑑定限度為0.01_γ,濃度界限爲1∶5,000,000。普通離子除外皆不干擾。鐵鹽在濃度高時,才妨碍銀的鑑定。

A new method for the synthesis of polyene acids has been described.This consists of the condensation of crotonic ester or sorbic ester with suitable alde- hydes,followed by hydrolysis.Thus a C4 or C6 side chain with conjugated double bonds can be introduced in a single step.Condensation of methyl cro- tonate with benzaldehyde and with furfural in the presence of alcohol-free sodium methoxide gives,after hydrolysis,cis-δ-phenyl-△~(αγ)-pentadienoic acid(m.p.137.5- 138°)and cis δ-2-furan-△~(αγ)-pentadienoic acid(m.p.109-111°)respectively;while...

A new method for the synthesis of polyene acids has been described.This consists of the condensation of crotonic ester or sorbic ester with suitable alde- hydes,followed by hydrolysis.Thus a C4 or C6 side chain with conjugated double bonds can be introduced in a single step.Condensation of methyl cro- tonate with benzaldehyde and with furfural in the presence of alcohol-free sodium methoxide gives,after hydrolysis,cis-δ-phenyl-△~(αγ)-pentadienoic acid(m.p.137.5- 138°)and cis δ-2-furan-△~(αγ)-pentadienoic acid(m.p.109-111°)respectively;while condensation of methyl crotonate with anisaldehyde under the same conditions gives a mixture which has been separated into two components:cis-δ-p-methoxy- phenyl-△~(αγ)-pentadienoic acid(m.p.115-118°)and its trans-isomer(m.p.180°, to liquid crystals and 220-221°,to clear liquid).All the above cis-acids have been converted without difficulty into the corresponding trans-acids. Condensation of sorbic ester with benzaldehyde in the presence of alcohol- free potassium methoxide gives,after hydrolysis,7-phenyl-heptatrienoic acid(m. p.189-190°,to liquid crystals and 199°,to clear liquid).

本文叙述了一种综合多烯酸的方法:将α-丁烯酸酯或α,γ-己间二烯酸酯与适当的醛缩合,再进行水解。这样,仅用一个步骤便可引进四个或六个碳原子的共轭双键的侧链。丁烯酸甲酯与苯甲醛或糠醛在去醇的甲氧基钠影响下缩合,得到顺-δ-苯基-戊间二烯酸(熔点137.5—138°)或顺-δ-2-呋喃-α,γ-戊间二烯酸(熔点109—111°);同样情形,α-丁烯酸甲酯与对-甲氧基苯甲醛缩合时得出顺-δ-对-甲氧基苯-α,γ-戊间二烯酸(熔点115—118°)及其反式的几何异构体(熔点:180°熔为液晶,220—221°熔为透明液体)。所有上述的顺式酸用弧光灯照射后,可全部转变为其相应的反式酸。α,γ-己间二烯酸甲酯与苯甲醛在去醇的甲氧基钾影响下缩合,水解后得到7-苯基-庚间三烯酸(熔点:189—190°熔为液晶,199°熔为透明液体)。
