A new neutral proteinase-producing strain 0031 has been selected from the air of Hangzhou Leather Plant.In primary observation of the cultural property of the strain 0031,we had found that it was more resemble to Bac. subtilis(A.S.1398),but the enzymogram of fermentative liquor after disc electrophoresis was different from Bac.subtilis (A.S.1398). The adequate cultural conditions for the strain have been established: composition of the liquid medium(%)is:soya bean 3%,corn flocer 2%,wheat bran 3%,KH_2PO_4 0.03%,Na_2HPO_4 0.4%,pH 8.0(before sterilization).After fermentation in shaking flasks(50ml/500ml/Δ,220 r.p. m.,ecc.dis.2.5cm.), at 28℃,for 38 hrs,the caseiaolytie activity was stablized at about 2000μg/ml, and the maximal activity could reach 2330μg/ml. During the process of study on the properties of enzyme-producing,we have found:1.suitable increase of aeration rate and pH,which will increase the enzymic produce and shorten the fermentative cycle;2.a tendency to slightly repress the enzymic produce and delay the enzymic peak,if fermentative temperature is above 30℃.3.no action of Zn■ and Ca■ on enzymic produce(test concen- tration ZnSO_4 0.005%,CaCl_2 0.3%).

我们从9株水解圈比值(水解圈直径/菌落直径)较大的(一般在7以上)初筛株中,经摇瓶复筛,筛选出一株中性蛋白酶产生菌0031菌株.经初步观察其培养特征较接近于枯草芽孢杆菌(A.S.1398),但其发酵液在盘状电泳上的酶谱,有别于枯草芽孢杆菌,其产酶的摇瓶发酵培养基为:豆饼粉3%,玉米粉2%,麸皮3%,KH_2PO_40.03%,Na_2HPO_40.4%,pH 8.0(消毒前).在50 ml(每500 ml 三角烧瓶)的装量,旋转式摇床(转速220次/分偏距2.5cm)温度28℃的条件下发酵,经34—38小时,酶效价稳定在2000单位左右(测定反应温度30℃)最高效价可达2330单位.在该菌株的产酶特性的探索过程中,我们发现1.适当的加大通气量和提高 pH 能提高产酶量和缩短发酵周期,但美中不足的是酶高峰期较短促,较不利于在发酵过程中控制产酶高峰点.2.提高发酵温度(30℃以上)略有抑制产酶的趋势或有明显的酶高峰期推迟的现象.3.Zn~艹和 Ca~艹(试验浓度分别为 ZnSO_40.005%和 CaCl_2 0.3%)对产酶无促进作用.根据目前所表现的生产性能,0031筛选株是理想的,值得联系实际目...

Let H be a language over alphabet Ω and L a language over alphabet Σ, each symbol in Ω being a homomorphism or an anti-homomorphism on L. The set H(L) = {X(w)\Xε.H, WεL} is said to be a bi-language form. In this paper it is shown that the class of language accepted in real time by nondeterministic reversal-bounded multitape Turing machines, NP and the class of the recursively enumerable sets are closed under bi-language form operations when the homomorphisms are linear-erasing, polynomial-erasing and arbitrary...

Let H be a language over alphabet Ω and L a language over alphabet Σ, each symbol in Ω being a homomorphism or an anti-homomorphism on L. The set H(L) = {X(w)\Xε.H, WεL} is said to be a bi-language form. In this paper it is shown that the class of language accepted in real time by nondeterministic reversal-bounded multitape Turing machines, NP and the class of the recursively enumerable sets are closed under bi-language form operations when the homomorphisms are linear-erasing, polynomial-erasing and arbitrary respectively.

如H,L属于某语言类,而H的每个字符都是L上的一个同态或反同志,则可定义H(L)={x(w)|x∈H,w∈L}为双语言形式。由读与头换向次数有界的非确定多带图灵机,在实时运行下所能接受的语言类称为BNP。本文讨论了在上述定义中的同态或反同志为线性消除、多项式消除及任意同态的情况下,双语言形式分别在BNP语言类、NP语言类及递归可枚举语言美中的封闭特性。

This paper describes the discovery of new superconductors,the rising ofthe international research on new superconductors,the comparison of thethrownin force of the main superconductor-researching countries and theevaluation of the research achievements.Developed by China and the UnitedStates separately,the Y-Ba-Cu-O material,which can steadily work in theliquid nitrogen temperature zone,has already been widely used for the researchon the superconducting film and wire.The worldwide research on the sinteredbody has met with the difficulty in increasing the critical current density,which only fluctuates now around 1,000A/cm~2.The orientation of thesuperconductor research and development is emphasis on the development ofthe superconducting film with high critical current density,the increase inthe critical current density of the sintered body and the deeper study on themechanism and room-temperature superconductors.

新超导体的发现及母界性新超导体研究的兴起,主要超导研究国投入力量对比和研究成果评估。美、中分别研制成功的 Y-Ba-Cu-O 材料可在液氮温区稳定地工作,已被世界普遍用于薄膜及线材等研究。世界烧结体研究已面临临界电流密度提不高难关,迄今仅能徘徊在1,000安培/厘米~2左右。发展与研究方向:着重点在高临界电流密度薄膜,以及提高烧结体临界电流密度、深入机理和室温超导。
