Studies of the surface acidity of zeolites have been made under conditions close to the reaction conditions by TPD technique. Two TPD peaks of desorbed pyridine were found on NaY zeolite. The peak I is considered to be the principal peak, before it the peak 1 is a shoulder, the former is regarded as species of pyridine adsorbed on Na+ ion in the supercage, the latter may be resulted from physically adsorbed pyridine(in the supercage).As the exchange-percentage of Ca2+ ion is increased to about 40-60%,...

Studies of the surface acidity of zeolites have been made under conditions close to the reaction conditions by TPD technique. Two TPD peaks of desorbed pyridine were found on NaY zeolite. The peak I is considered to be the principal peak, before it the peak 1 is a shoulder, the former is regarded as species of pyridine adsorbed on Na+ ion in the supercage, the latter may be resulted from physically adsorbed pyridine(in the supercage).As the exchange-percentage of Ca2+ ion is increased to about 40-60%, a new desorption peak III appears in the high temperature range, and at the same time the shoulder peak I gradually disappears.The products desorbed from the zeolites were identified by chromatogra-phic analysis, only pyridine is detected. The total amount of adsorbed pyridine gradually decreases as the amount of Ca2+ ion in the zeolite is increased. This indicates that the pyridine is adsorbed on Na+ ion very strongly. Consequently, for any alumina-silicate sample with high Na+ content, its surface acidity cannot be simply expressed by the total amount of pyridine adsorbed.

用程序升温脱附技术,在接近反应条件下研究沸石的表面酸性。在NaY沸石上吡啶的程脱峰有二,峰Ⅱ为主峰,其前沿有一肩膀峰Ⅰ,前者为吡啶吸附于Na~+上的物种,后者可能为残留的物理吸附吡啶(在超笼中)。随Ca~(2+)离子交换度的增加,在交换度40—60%间程脱峰谱发生质的变化,在高温区另出现一脱附峰(峰Ⅲ),与此同时峰Ⅱ向低温迁移,峰Ⅰ渐趋消失。经色谱鉴定,脱附产品中只有吡啶存在,其总吸附量随Ca~(2+)交换度增加而递减,表明吡啶分子在Na~+上的吸附极为显著,因此对Na~+含量甚高的硅铝样品,不能采用吡啶的总吸附量来作为酸性数量的衡量标准。

A single dose of reserpine(2mg/kg body weight)depleted the noradrenaline-(NA)content in submandibnlar gland(SMG)of adult IGR/JCL mice of both sexesto unmeasurable levels in 24 hours.Then,the NA content began to recover andreached to pretreatment levels in 12 days.During this period,NA content of themale was always about twice that of the f(?)male.When the preganglionic nervetrunk was avulsed on one side,the NA content of the gland in both sexes fell to about80% of their unoperated sides,but...

A single dose of reserpine(2mg/kg body weight)depleted the noradrenaline-(NA)content in submandibnlar gland(SMG)of adult IGR/JCL mice of both sexesto unmeasurable levels in 24 hours.Then,the NA content began to recover andreached to pretreatment levels in 12 days.During this period,NA content of themale was always about twice that of the f(?)male.When the preganglionic nervetrunk was avulsed on one side,the NA content of the gland in both sexes fell to about80% of their unoperated sides,but NA content of the male always kept about twicethat of the female during the course of recovery after reserpine.Nerve growth factor(NGF)content in male and female SMG in this strain ofmice was measured by a bioassay method.It was found that the NGF content in themale SMG was about 94-fold higher than that in the female.As exogenous NGFselectively increases tyrosine hydroxylase activity in sympathetic neurons and NAcontent in SMG,the higher NA content of the male SMG than in the female in therecovery course after reserpine might result from endogenous NGF effect on the en-zyme in sympathetic neurons.

给ICR/JCL品系的成年小鼠1次注射利血平(2mg/kg体重)后24小时,其颌下腺(SMG)的去甲肾上腺素(NA)贮存能够被耗竭。在注射后第12天,NA 含量恢复到利血平处理以前的水平。在恢复过程中,雄性腺体的 NA 含量均为雌性的2倍左右。切断颈上神经节(SCG)的节前神经,雌雄腺体的 NA 含量都下降至对照侧的80%左右。消除节前神经的影响以后,在 NA 的恢复过程中,雄性腺体的 NA 含量仍然是雌性的2倍左右。利用神经生长因子(NGF)生物测定法,我们测得本品系成年雄性小鼠 SMG 的 NGF 含量为雌性小鼠的94倍左右。正如外源性 NGF 能选择性地提高交感神经元内的酪氨酸羟化酶活力与 SMG 的 NA 含量一样,在利血平处理后的恢复过程中,雄性腺体比雌性腺体具有较高的 NA 含量可能是由于内源性 NGF 对交感神经元内酪氨酸羟化酶产生效应的结果。

The Archean Taihua high-grade metamorphic belt aloeg the W-S margin of the north China craton can be divided into two rock units,(1) Quartzo-Feldspathic gneisses (tonalitic gneisses) containing biotite and plagioclase, quartz with or without potash feldspar and honblend. Chemically, they have high Na/K rations (average 3.22) similar to tonalites. These rocks often constitute domes.(2) Supracrustal rocks including meta-volcanics (granulite, amphibolite and komatiitic gneiss) and metasediments (sillimanite-garnet...

The Archean Taihua high-grade metamorphic belt aloeg the W-S margin of the north China craton can be divided into two rock units,(1) Quartzo-Feldspathic gneisses (tonalitic gneisses) containing biotite and plagioclase, quartz with or without potash feldspar and honblend. Chemically, they have high Na/K rations (average 3.22) similar to tonalites. These rocks often constitute domes.(2) Supracrustal rocks including meta-volcanics (granulite, amphibolite and komatiitic gneiss) and metasediments (sillimanite-garnet gneiss, graphite gneiss, marble and quartzite) which constitute khondalite.From field, petrographic and geochemical date, the quartzo-feldspathic gneisses are interpreted as plutonic tonalites, Meta-volcanics are of the tholeiitic origin. Without doubt, khondalite is a series of sediments and its sedimentary environment was an epicontinental platform or shelf. Available results suggest a shallow water and stable tectonic setting for the Taihua high-grade metamorphic belt. Clearly, it is different from Archean greenstone belt, for example, the Dengfeng greenstone belt located adjacent to it on the north.

位于华北地块西南缘的太古代太华高级变质带,是由长英质片麻岩和上壳岩两套经受多期变质作用的高度变质杂岩所组成。空间上位于该带下部,呈穹窿状产出的长英质片麻岩具太古代英云闪长岩特征。上壳岩套上部的富铝片麻岩以及与其伴生的大理岩、石英岩是一套类似孔兹岩系的陆架或陆缘台地型变质沉积建造,而其下的变质基性岩的原岩属拉斑玄武岩。根据建造特征,结合地球化学分析,推测太华高级变质带中的上壳岩套是在已存英云闪长质地壳、经沉降而造成的浅水稳定条件下形成的。这显然与北部拉张条件下形成登封绿岩带的环境不同。也有别于显生宙之后发生附冲作用的环境。
