However, among the 65 who were not confirmed as AS patients, 46 subjects presented the syndrome as HLA B27 amplifying bands, and the positive rate was 70.3%(RR=46,P< 0.01).

Method:15 subjects diagnosed as AS patients were put in a clinical group,in which there were all together 30 sacroiliac joints diagnosed by CT as sacroilitis respectively in the clinical stages of 0,Ⅰ,Ⅱ,Ⅲ and Ⅳ.

that As analysis line is rarely impactedwhen the concentrtiona of Ag, Ba, Fe, Mg, Ni and Pbare 100 times as much as As concentration, but As analy-sis line is impacted to some extent when the concentra-tions of Al and Cr are 100 times as much as As conentra-tion. Some methods for correcting and eliminating the in-terference of Al and Cr are presented.

The characterization and mechanism of corrosion of platinum by common optical glass materials, such as nitrates (KNO_3, NaNO_3)carbonates(Li_2CO_3, NCO_3, K_2CO_3)as well as As, Sb, Pb, Ba, La oxides etc, are studied when they are affected by different temperatures and at different times.

The contents and distribution laws are studied of such trace elements as As, Ba, Be, Cd, Co, Cr, Cu, Hg, Li, Mn, Ni, Pb, Se, Sr, V, Zn and Zr in the coal of various mining areas in Northeast China and eastern Inner Mongolia.

When i > 220 A/m~2, a small amount of As~(5+) and Bi~(3+) begins to deposit on cathode, and they exist in the form of As, As_2O_3 and Bi_2O_3 in the deposited copper, and roughen the grain of copper crystal.

Eleven metals content such as As、Cd、Co、Ci、Cu、Mn、Ni、Pb、Sb、Se、Zn in dyestuffs are quickly determined via combination of microwave incineration with ICP-AES.

As as illustration of the possible applications of the results obtained here we formulate and prove a limit theorem for a semi-Markov process.

The possibility of recovering the Gell-Mann-Low function in the asymptotic strong-coupling regime by known first-order perturbation-theory (PT) terms βn and their asymptotics as as n → ∞ is investigated.

Using scanning tunneling microscopy, the native-oxide film on epitaxial n-GaAs(100) was found to be formed by tightly joining nanoclusters involving oxides of Ga and As as well as an excess As layer on the interface between Ga2O3 and n-GaAs.

The fluid-assisted layering of mafic-ultramafic massifs resulted in the contrasting distribution of PGM in response to uneven distribution of sulfur (as well as As, Te, and Bi) during liquid immiscibility.

The electronic control allows the multiplexer to work as as simple two input logical gates such as AND, NAND, OR, NOR, XOR and XNOR.

Neosalvarsan is proposed as a reagent for silver ions. It forms a brown insoluble complex. I. L. 2γ; C. L. 25,000. By Job's continuous variation method, light absorption-composition curves were obtain- ed. The maximum corresponds to silver: neosalvarsan = 2: 3. It is proposed that the-As = As-group may be considered as an analytical functional group for silver ions.

The“dead-stop end-point”method of Foulk and Bawden has been found very convenient for the simultaneous determination of antimony and arsenic without previous separation.Cerie sulfate solution is used as titratant.Antimony is deter-mined first in 6 M HCl solution at 0~C.At this temperature the Sb(Ⅲ)-Sb(V)system is reversible while As(Ⅲ)-As(V)not.Then the solution is adjusted to 4 M HC1 and warmed to room temperature with the addition of IC1 as catalyst to render the As(Ⅲ)-As(Ⅴ)system reversible and the titration...

In the restricted predicate calculus we deal with functions, namely, the thing functions which take individuals as as values and the propositional functions i.e. predicates. Usually they take only individuals as arguments. Such a restriction seems, however, too severe. It would be better if we allow them to take also propositions as arguments. Besides, we deal also with operators, namely, quantifiers and descriptions. By the same reason, it would be better if we allow them to take also terms as their...

In the restricted predicate calculus we deal with functions, namely, the thing functions which take individuals as as values and the propositional functions i.e. predicates. Usually they take only individuals as arguments. Such a restriction seems, however, too severe. It would be better if we allow them to take also propositions as arguments. Besides, we deal also with operators, namely, quantifiers and descriptions. By the same reason, it would be better if we allow them to take also terms as their scopes and to take propositional variables as the directive variables. Further, in the extended predicate calculus, we deal also with functions of higher order and operators of higher order. We usually consider them to be quite different from each other. In the present paper, we show that: First, the functions of the second order are the same as the operators of the first order. For example, the expression φ(A), where φ is a function of second order, and A is a two-place first order function, may also be represented as φ_(xy) A(x, y), where φ_(xy) is an operator of first order with two directive variables x and y. On the other hand, the expression lim(x→a) f(x), where lim is an operator of first order, may also be represented as lim(a,f), where lim is now a function of second order with one individual argument and one functionargument (of first order). In general, the functions of order n+1 are the same as the operators of order n. (However, see the following.) Secondly, when we apply functions of second order (i.e. operator of first order) to functions of first order to form a term or a formula, it is not that the former (of higher order) take the latter (of lower order) as arguments (so asserted by the prevailing opinion), but that the former become arguments of the latter, or at least that the former bind the empty places of the latter. Anyhow we cannot say that the latter are arguments of the former. Hence the usual expressions (?)xa(x) and lim(x→a) f(x) should be written as (a(?) and (f lim a or as Aa(i) and lim a f(i). (We stipulate that if operators should be written after the scope they must be coupled with left parentheses.) Thirdly, since the first order operators (i. e. functions of the second order) never take functions of first order as arguments, there is no room to give rise to higher functions and operators. Hence we have only individuals, propositions, functions (of first order) and operators (of first order, i.e. functions of second order). The extended predicate calculus would become much simpler.
