本文应用闪光光解共振荧光技术测量了OH自由基和乙二氧基甲烷气相反应的绝对速率常数,k=(1.68±0.16)×10^(-11)cm.3 m.lecule^(-1)s^(-1),统计分析求得误差为2σ。实验时系统总压力为25—50Torr(以Ar为稀释气体)。我们曾根据正烷基单醚的动力学测量结果来计算CH_3和CH_2的反应活性值。现发现此活性值此正烷烃对应值约大2倍,但能够精确地估算OH自由基与二乙氧基甲烷气相反应的速率常数。而且表明烷基链中次甲基的位置及数目对其反应活性贡献甚小。

Four different varieties of charnockitic rocks, with different m.des of form.tion, from.the m.soproterozoic Natal belt are described and new C isotope data presented. Excellent coastal exposures in a num.er of quarries and river sections m.ke this part of the Natal belt a good location for observing charnockitic field relationships. Whereas there has been m.ch debate on genesis of charnockites and the use of the term.charnockite, it is generally recognized that the stabilization of orthopyroxene relative to biotite in granitoid rocks is a function of low aH2O （-- high CO2）, high tem.erature, and com.osition （especially Fe/（Fe ＋m.））. From.the Natal belt exposures, it is evident that syn-em.lacem.nt, m.gm.tic crystallization of charnockite can arise from.m.ntle-derived differentiated m.lts that are inherently hot and dry （as in the Oribi Gorge granites and m.nster enderbite）, as well as from.wet granitic m.lts that have been affected through interaction with dry country rock to produce localized charnockitic m.rginal facies in plutons （as in the Portobello Granite）. Two varieties of post-em.lacem.nt sub-solidus charnock- ites are also evident. These include charnockitic aureoles developed in leucocratic, biotite, garnet granite adj.cent to cross-cutting enderbitic veins that are attributed to m.tam.rphic-m.tasom.tic processes （as in the Nicholson＇s Point granite, a part of the m.rgate Granite Suite）, as well as nebulous, patchy charnocki- tic veins in the m.rgate Granite that are attributed to anatectic m.tam.rphic processes under low-aH2O fluid conditions during a m.tam.rphic event. These varieties of charnockite show that the required physical conditions of their genesis can be achieved through a num.er of geological processes, providing som. im.ortant im.lications for the classification of charnockites, and for the interpretation of charnock- ite genesis in areas where poor exposure obscures field relationships.

本文讲述了一种新型的陷门渐缩公开密钥密码体制。其加密方程基于一般的模数渐缩方程,但与m.rkle—Hellm.n方法不同,渐缩分量不是非得具有超上升结构。其陷门依赖于渐缩分量的模数和基数形式之间通过中国剩余定理的变换,其保密基于一个256位二进制复合数的质因子分解。所得的密码体制具有高密度,近似36‰的消息扩展及一个14k比特的公开密钥。这与超过100‰扩展及80k比特公开密钥的m.rkle—Hellm.n方法相比要好的多。当与RSA方法相比时该方式的主要优点即为速度。具体地说,象本文建设的这种渐缩方式,其速度可比RSA方法的快几个数量级。

本文给出一种潮流计算的新方法。由于支路电压与角差通常较小,线路损耗也较输送功率小得多,因而得到了以支路电压与角度为变量,并且在迭代过程中考虑进线损的新的潮流计算模型。模型中支路电压与角度是线性的,而线损是二次型的,这种形式在通常的规划计算中可以更为直观。用这种方法所得出的只包含支路电纳的对称、解耦系数矩阵,具有一些特殊性能,可以大大改善在线潮流计算的功能。 14节点、11节点、30节点、47节点和118节点网络的算例用来证明这一方法的有效性。
