1. The stationary potentials of zinc electrode in potassium hydroxide solutions (from 0.2 N to saturated solution) have been measured. When the concentration of potassium hydroxide is greater than 1 N, the φ_c~logaαкон plot shows a linear relation, the slope of which is found to be-59 mv.2. The anodic polarization curves of zinc electrode in potassium hydroxide solutions (from 1.07 N to 8.31 N) were measured, the linear portions of which have a slope of 40 my. It has been found that at constant current densities, when the logαкон changes by one unit, the anodic potential shifts about 80 mv.3. The corrosion rates of zinc in potassium hydroxide solutions (from 1.61 N to 9.81 N) have been determined by gravimetric method. The log i_c~log αкон plot shows a linear relation, the slope of which is found to be about 0.4.4. On the basis of the results obtained the mechanism of the anodic dissolution of zinc electrode in potassium hydroxide solutions is suggested as follows:Zn+OH~-→ZnOH+e (a)ZnOH+OH~-→Zn(OH)_2+e (b)The step (b) is rate-determining.5. It has been found that the self-dissolution of zinc electrode in potassium hydroxide solutions (conc.>1N) is due to two conjugated reactions, one of which is the above suggested anodic reaction and the other is the cathodic reaction of hydrogen evolution on the zinc electrode.

In respect to rice,wheat and corn crops,the quantitative relation of planting rate (x)to the number of heads or ears per mu (Y) may be expressed by modified hyperbolic equation:Y=x/(a+bx) (3)where“a”and“b”are two positive parameters.The value of“a”is the regression coefficient of1/yon1/x,which means when the area occupied by each plant (1/x) is increased one unit,thearea for producing one head or ear (1/Y) will increase“a” unit;and“a”also expresses theplant number for producing one head or ear,as x→O (extremely thin planting rate).Thevalue of“b”is the regression coefficient of x/Y on x,which means when the planting rate (x)is increased one unit,the plant number for producing one head or ear (x/y) will increase“b”unit;furthermore,“b”is the area for producing one head or ear,too,as 1/x→O (extremelydense planting rate).From equation (3),the following main formulae may be obtained:1.The equation for expressing the quantitative relation of planting rate (x) to the averagenumber of heads or ears per plant (y) is:Y=1/a+bx (17)2.The equation for expressing the quantitative relation of plantnig rate (x) to thedifference between the number of heads or ears per mu and that of plants per mu (D) is:D=(x(1-a-bx))/(a+bx) (9)3.The planting rate for the maximum number of heads or ears per mu exceeded thenumber of plants per mu (x_1) is:x_1=(a-a~(1/2))/(-b) (13)4.The planting rate with the number of heads or ears per mu equal to that of plantsper mu (x_m) is:x_m=(1-a)/b (10)5.When the planting rate per mu is varied in the open interval (0,∞),the number ofheads or ears per mu will be varied in (0,1/b) (8)while the average number of heads or ears per plant will be varied in(1/a,0) (18)In this article,17 formulae(see formulae 4—20)for expressing various characteristics ofquantitative relation of planting rate to the number of heads or ears have been derived fromequation (3).The method of derivation of equation (3) based on experimental data has beendiscussed (see formulae 21—24) together with a substantial example.

Escherichia coli strains 275 and 396 are resistant to antibiotics Tc, Ap, Cm, Sm and Su. Shigella flexneri strains 233 and 416 are resistant to Tc, Cm, Sm and Su. Except E. Coli 275, these strains transfered their resistance to recipient strains as one unit at a frequency of about 10-5-10-7 even when selected for either one of the drugs. It seems that the genes governing these resistances were located on plasmids.We designated these plasmids as EE275 (nonconjugative), ER396, DE233 and DR416 respectively.When the above bacterial strains were mated with E. coli strain J5-3/R144drd3 (Kmr), strains with two coexisting plasmids were constructed.We used these strains with two coexisting plasmids as donor strains, and selected for Ap or Sm resistance to obtain ApKm or SmSuKm resistant transconjugant. These transconjugants transfered their resistance to recipient strain as one unit at a frequency of about 10-4-10-2 which was also the frequencies for B144drd3 plasmid.Biochemical studies have shown that the Ap resistant gene of BE275 and EE396 mediated the formation of β-lactamase, and the Sm resistant gene of DE233 and DK416, the formation of the ATP-dependent streptomycin inactivating enzyme. The ApKm and SmSuKm transconjugants acquired the ability to synthesize the two kinds of enzyme.According to these results, it is suggested that on the EE275 and EE396 as well as DE233 and DE416 plasmids transposable "Ap resistant gene and transposable SmSu genes existed respectively.

ER275、ER396(Tc~r、Ap~r、Cm~r、Sm~r、Su~r)与DR233、DR416(Tc~r、Cm~r、Sm~r、Su~r)是来自临床的抗药质粒。当带有这些质粒的菌株分别与大肠杆菌J5-3/R144drd3(Km~r)配对时,组成了两种质粒共存的菌株。用这种质粒共存的菌株作为接合转移的给体,并以Ap或Sm作为选择药物,得到ApKm或SmSuKm抗性类型的转移接合子,此种转移接合子能将ApKm或SmSuKm抗性作为一个单位连锁地转移到受体菌株,而且转移频率与R144drd3相似。 生化的研究表明,ER275、ER396质粒中的Ap抗性基因编码β-内酰胺酶,DR233与DR416质粒中的Sm抗性基因编码链霉素钝化酶,而带有Ap Km或Sm Su Km重组质粒的转移接合子也分别具有了合成这二种酶的能力。因此我们推测在ER275、ER396与DR233、DR416质粒中分别有可转座的Ap抗性基因与可转座的SmSu抗性基因存在。
