Using LEMAO-3G as a basis function set, the scale factor set for benzene molecule was optimized as following: ζ_(ms) =1.26,ζ_(c1s) =1.0039,ζ_(c2π) =1.1043, ζ_(c2π)=1.00761.With this set of scale factors our calculated total energy is-229.167274 Hartrees and Virial coefficient 1,00000 for benzene, which ful fil the requirements of the basic principle of quantum mechanics.The resulting valence orbital energies agree fairly well with the experimental data of photoelectron spectroscopy, and also with the calculated results of I.Fischer-Hjalmars and P.Siegbahn, which are reported to bo very near to the Hartree-Fock limit, but the basis function set which we used is completely different from theirs,and much simpler.The ratio of the calculated atomization energy to the experimental value is improved by about 17.6% over the ratio which may be obtained by the simple assumption "delocalization".From the analysis of these results, we roach the following conclusion: The cause of "aromatic stability" of benzene is not only due to the "delocalization" effect of the atomic orbitals in its cyclic conjugated system, but also to their "contraction" or "localization" effect, which is contrary to and is closely associated with the "delocalization" effect and plays a very important role in aromaticity.Furthermore,it is the σ-orbitals, rather than theπ-orbitals, whose "delocalization" and"localization" effects play a more important role in the "aromatic stability" of benzene.The σ-orbitals are contracted to a rather great extent (scale factor ζ_(c2α) increases from 1 to 1.1043), but the π-orbitals are only contracted to a small extent (ζ_(c2π)only increases from 1 to 1.00761).so the π-electrons are in a more "diffused" state than the σ-electrons.This makes the π-electrons, on the one hand, retain greater total energy, and thus become a second important cause of their greater mobility while the first causc being the "delocalization" of π-orbitals.On the other hand, this makes the energy of the σ-electrons decreased by even a greater extent, and thus makes the benzene molecule (as a whole) more stable.This is to be considered as the main cause of the fact,that the benzene molecule is rather stable as a whole, but its π-electrons are relatively mobile.

用LEMAO-3G作为基函数集合,优选出苯分子的最佳调节因子组:ζ_(H1s)=1.26,ζ_(c1s)=1.0039,ζ_(c2σ)=1.1043,ζ(c2π)=1.00761.用此调节因子组计算得苯分子的总能量为-229.167274Hartrees,维里系数为1.00000.可较满意地符合量子力学基本原理的要求.所得各价轨道的能量与光电子能谱的实验数据基本相符,与Fischer Hjalmars和P.Siegbahn的很接近于Hartree-Fock极限的计算结果也颇为一致.但我们所用的基函数集合与他们所用的完全不同,而且简单得多.计算所得原子化能所占实验值的比例比由单纯“离域”观点计算的改进约17.6%.分析这些计算结果可得结论:苯分子的“芳香稳定性”的原因,不仅在于其环形共轭体系中诸轨道的“离域”效应,与之相对立而又与之紧密联系着的诸轨道的“收缩”或“定域”效应也起有十分重大的作用.并且σ-轨道的“离域”与“定域”在其中起有比π-轨道更为重要的作用当σ-轨道因“动能压力”的减小而发生程度很大的“收缩”(调节因子由1增大为1.1043)时,π轨道仅发生程度很小的“收缩”(调节因子由1仅增大为1.007...

It is considered in this Paper that the poor and good harvest ofwinter wheat in Shanxi Province depends on the key factor-autumnrainfall in the sowing stage and the early growing period of young seed-lings (from the middle of September to late November), with the droughtequivlant of 75 mm based on an analysis of rainfall information of 867years of 43 county weather stations and the winter wheat yielding infor-mation by means of the principle of drought equivalent of the well-known ecologist G. Azzi. The second important stage is the rainfall(from December to February next year) in the winter dormancy withthe drought equivalent of 40 mm.In the above growing period of winter wheat, it can be divided intothe rare belt of drought frequency (2.5-5), the intermediate-long belt ofdrought frequency (2.5-5) and the usual belt of drought frequency (7.5)according to the drought frequency (still less than 2.5) from the southto the north. It can be further zonifized into the microarid region, thelight-arid region, the arid region and aridest region for winter wheatin Shanxi Province based on the relationships between the drought fre-quency and distribution of winter wheat.The geographical experiment illustrated that the selection of wheatvarieties of rainfed lands and the climatic constraints are the first, butthe soil constraints are the second. It is obvious that reduction withless in the drought year or even reduction without any yield can entirelybe avoided by the use of drought-resistant varieties against drought anddryness under the existing conditions. On the other hand, if, in a goodyear, the unsuitable varieties are selected, the favourable rainfall watermay not be used to the fullest extent, so that the due bumper harvestcan not be won. The non-extreme drought is a common phenomenon, theoccurrence and frequency of which have a close relation with the fluc-tuation of yields of winter wheat.

本文根据43个县气象站867年次的隆水资料和小麦产量资料进行分析,运用了阿齐(G.AZZI)的干旱当量方法,认为决定山西小麦丰歉关键的降水是播种期至幼苗生长初期(中/9—下/11)的秋雨,干旱当量为75毫米。次一个重要时期是冬季休眠期(12—2月)的降水,其干旱当量为40毫米。 在上述小麦生育期中,根据干旱频率(级差2.5)从南至北划分为干旱频率稀少带(频率指标1—2.5)、干旱频率中常带(2.5—5)和干旱频率经常带(>5)。根据山西小麦干旱频率带与小麦分布的关系,进一步区划为山西小麦微旱区、轻旱区、干旱区和最旱区。 通过地区性试验表明,旱地小麦品种的选择应该重视气候制约和土壤制约。显然,用抗旱品种对付干旱,可以做到在现有条件下,旱年少减产,甚至不减产,是大面积经济有效的抗旱措施。另一方面,在丰年若品种选用不当,则不能充分利用有利的降水,因而不能得到应有的丰收。 非特大性的干旱是经常发生的,其发生的时间和频率与常年小麦产量的起伏关系十分密切。

Based on physico-chemical properties and analysis of spectra, zhengguangmycin A_6 was identified as bleomycin A_6. As reported in literature, the addition of a certain amine to the fermentation media increased the ratio of production of the bleomycin which contains the added amine as the terminal moiety. Spermidine (0.36 mg/ml) Was very efficiently incorporated into bleomyein A_5 and completely suppressed the production of other bleomycins.

Based on physico-chemical properties and analysis of spectra, zhengguangmycin A_6 was identified as bleomycin A_6. As reported in literature, the addition of a certain amine to the fermentation media increased the ratio of production of the bleomycin which contains the added amine as the terminal moiety. Spermidine (0.36 mg/ml) Was very efficiently incorporated into bleomyein A_5 and completely suppressed the production of other bleomycins. However, it is an exception for bleomycin A_6, which is present in natural bleomycins in only trace amounts, even after the addition of its terminal amine (spermine 0.30 mg/ml) to the fermentation media. But the amount of zhengguangmycin A_6 is different. Under normal conditions the amount of zhengguangmycin A_6 in natural zhengguangmycins is usually over 10%, in some batches, reaching 15% and was the second important component in an amount next to zhengguangmycin A_5 (pingyangmycin). This suggests that the producing strain of zhengguangmycins, Streptomyces verticillus var. pingyangensis nov. is different from that of bleomycin, S. verticillus.

争光霉素A_5已鉴别为Bleomycin A_6,在争光霉素复合物中所占比例一般在10%左右,在某些批样中可高达15%以上。文献报告Bleomycin A_6在天然产的Bleomyein复合物中只有痕量。通过向发酵培养基中加入特定组分的末端胺可大大提高其特定组分在复合物中的含量比而其它组分的产生则不同程度地被抑制。但Bleomyein A_6例外,即使向培养基中加入其末端胺精胺(0.3mg/ml),在所产生的复合物中大大增多的组分是Bleomyein A_6,而Bleomycin A_6仍只有痕量。这表明争光霉素产生菌有和Bleomycin产生菌明显不同的特点。
