1 Finally, the central globe, Zn c, follows the same cruciform line of disintegration.

2 Experiment 121.—Burn a strip of Zn foil, and note the color of the flame and of the product.

3 The method can be used for analyzing 5 elements ( Cu, Zn, Co , Fe, Mn ) in soybean and soybean � � s substitute by AAS.

本文采用干法灰化和湿法消化溶解样品,原子吸收法测定大豆及其乳制品中Zn 、 Cu 、 Co 、 Fe 、 Mn等元素.

5 The spheres within the globes at the base of the spikes, Zn b, behave as a cross—the cross is a favourite device in the II a groups.

6 Eighteenamino acids ( Such as Val , Leu, Lys, etc. ), Vitamin C, Vitamin B 1、 Vitamin B 2, and fourteen microelements ( Such as K, Ca, Mg, Fe and Zn, etc. )

测出了果汁中含有缬氨酸 、 亮氨酸 、 赖氨酸等18种氨基酸, 维生素C, 维生素B_1,维生素B_2, 以及K 、 Ca 、 Mg 、 Fe、Zn等14种微量元素.

7 Geochemistry of CI chondrites: major and trace elements, and Cu and Zn isotopes.

8 The spectral proper - ties of the reactions of T ( 4 - MOP ) PS _ 4 , withCu ~ ( 2 + ), Pb ~ ( 2 + ), Zn ~ ( 2 + ), Cd ~ ( 2 + ), Co ~ ( 2 + ) and Mn ~ ( 2 + ) have beeninvestigated.

探讨了试剂的特性及其与Cu~ ( 2+ ) 、 Pb~ ( 2+ ) 、 Zn~ ( 2+ ) 、 Cd~ ( 2+ ) 、 Co~ ( 2+ ) 和Mn~ ( 2+ ) 反应的最适条件.测得了这些配合物的配位比 、 摩尔吸光系数.

9 Of course Zn must have a stronger chemical affinity for Cl than H has, or the change could not have taken place.

10 The scale bar in the Zn quadrant of the maps is as designated and applies to all parts of the figure.

11 This method is able to measure Mn, Cu, Pb, Zn, Co , Ni and P quickly.

该方法也可同时用于:Mn 、 Cu 、 Pb 、 Zn 、 Co 、 Ni、P等杂质元素的快速测定.

12 Sn, Pb, and Zn are somewhat soluble in vegetable acids.

13 Large amounts of 65 Zn are produced in copper exposed to accelerator beams.

14 Zinc is sublimed-in the form of zinc dust-like flowers of S. Granulated Zn is made by pouring a stream of the molten metal into water.

15 This is done by plunging the wire or the sheets of iron into melted Zn.

16 Construct a diagram of the apparatus, marking the Zn in the liquid +, since it is positive, and the C, or other element, -.

17 Pewter is composed of Sn and Pb; brass, of Cu and Zn; German silver, of brass and Ni; bronze, of Cu, Sn, and Zn; aluminium bronze, of Cu and Al.

18 Describe the use of Zn as an alloy.

19 In the union of Zn and O, each has two bonds; H hence they unite atom with atom, Zn = O, or ZnO.

20 The most preferred components of hot galvanizing Zn - Bi alloys are determined.
