The results calculated by perturbational molecular orbital (PMO), Huckel molecular orbital (HMO) and self-consistent field molecular orbital (PPP) methods are very similar in various aspects for the alternative hydrocarbons. A linear correlation exists between the ionization constant (pK_α) and the charge density of active atom (q_x) or the difference of conjugative energies between conjugative acid-base pair (ΔEπ). However, the pK_α values of aromatic carboxylic acids and nitrogen-containing heterocycle...

The results calculated by perturbational molecular orbital (PMO), Huckel molecular orbital (HMO) and self-consistent field molecular orbital (PPP) methods are very similar in various aspects for the alternative hydrocarbons. A linear correlation exists between the ionization constant (pK_α) and the charge density of active atom (q_x) or the difference of conjugative energies between conjugative acid-base pair (ΔEπ). However, the pK_α values of aromatic carboxylic acids and nitrogen-containing heterocycle are inversely proportional to q_x or ΔEπ. It shows that in the fomer case the pK_α value is governed chiefly by the dipole moment while in the latter case the pK_α value is controlled by the repulsion integral between the lone electron pair in nitrogen atom and the electrons in the highest occupied molecular orbital.

本文用微扰分子轨道(PMO),Hackel分子轨道(HMO)和自洽场分子轨道(PPP)方法研究了芳香酮、芳香胺、酚和含氮杂环等化合物的解离常数(pK_α)和π-电子分布的关系。结果表明对交替烃,PMO,HMO和PPP在某些情况下,有类似的平行结果。pK_α与活性原子上的电荷密度q_w有着良好的线性关系。但对芳香甲酸和含氮杂环,pK_α与q_x有反比关系。对芳香甲酸pK_α主要由偶极矩决定。而含氮杂环主要由氮原子中的孤对电子与最高充满轨道中的电子间的排斥积分所控制。

Sixty chemicals were studied to select the effective chemicals to increase the sugar content of sugarbeet.It was discovered that the sugar-in-crease-agent Ⅱ-aromatic carboxylic acid compound-was an excellent sugar-increase-agent. The field experiment was carried out in many regions and large area from 1984 to 1986. The total area was more than 2000 mu. The results showed that when sprayed with the effective dosage of 50-60g/mu in late August, it could usually increase the root yield by 7-17 %, average...

The results showed that when sprayed with the effective dosage of 50-60g/mu in late August, it could usually increase the root yield by 7-17 %, average 9.34%; sugar content by 0.4-2.5% (most of which were between 0.6-1.4%) ; sugar production by 11-33%, average 20.2%. The average sugar production per mu was increased by 56Kg.
