Further research indicates that the polymerization of HEMA was induced by the disproportionation of dihydropyridinium. From results above, the mechanism of Gluma as a desensitizer could be proposed as follows.

发现戊二醛与牛血清蛋白之间的反应可以使水溶液中的HEMA聚合,进一步研究发现HEMA的聚合与二氢吡啶盐歧化过程所产生的自由基有关。

Flowers unisexual. Male inflorescence precocious, elongate, pendulous, with numerous overlapping bracts; each bract usually subtending a small dichasium with 1-3 male flowers; stamens as many as and opposite sepals or, if sepals obsolete, then stamens of inflorescence to 20; filaments very short, connate or nearly so; anthers 2-loculed, thecae connate or separate, opening by longitudinal slits.

雄花序先有花,拉长,下垂,具多数重叠苞片;通常的每苞片对着一小的二歧聚伞花序具1-3雄花;同数的雄蕊和与萼片对生或,如果萼片废退,然后对20的花序的雄蕊;花丝非常短,合生或近合生; 2室的花药,合生的或分开的囊,以纵裂缝开阔的。

PROF.: Intelligent people should be aware that this is a false dichotomy.

聪明的人应该知道这是一个假的二歧分枝。

Thecompositions of raw material and products were identified with GC-MS, the results indicatedthat the products were composed of (β-acryloxyl ethyl) esters of dihydropimaric acid anddehydrogenated abietic acid, and their relative amounts was consistent with the amount ofdihydropimaric acid and dehydrogenated abietic acid in the disproportionated rosin.

论文还采用GC-MS对原料和产物的组分进行了鉴别,结果表明酯化产物由二氢海松酸酯和脱氢枞酸酯组成,且其相对含量与歧化松香中二氢海松酸和脱氢枞酸组成基本一致。

Cymes mainly on branched axis, 3 or 4 × dichotomously branched, branches slender and patent; peduncle 1-2 cm, secondary peduncle 5-15 mm; pedicels very short, less than ca. 3 mm or absent.

聚伞花序主要在分枝的轴上,3或者4二歧分枝,分枝纤细和开展;花序梗1-2厘米,副花梗5-15毫米;非常短的花梗,少于长约3毫米或无。

The discovery of dichotomously bifurcated fronds of Gigantonoclea from the late Early Permian Tongtseyan Formation in Fujian Province is thus a matter of vital importance, for it brings a much closer relationship between the Asian and the American gigantopterids, although there are still many substantial differences between them.

因之,二歧分叉蕨叶在中国的发现具有十分重要的意义,它使东亚与北美大羽羊齿植物之间的关系变得更为密切,虽然其间仍存在不少实质性的差异。

When Gluma is applied in vivo, two reactions occur: first, GA reacts with part of the serum albumin in dentinal fluid, which induces a precipitation of serum albumin; and, second, the reaction of GA with serum albumin forms dihydropyridinium, whose disproportionation gives rise to free radicals, and the free radicals induce the polymerization of HEMA.

首次提出Gluma的脱敏机理为:当Gluma涂在过敏的牙本质上时,首先戊二醛交联牙本质液中的血清蛋白并产生沉淀;同时戊二醛与血清蛋白的反应产生二氢吡啶盐,它发生歧化反应,歧化过程中会有自由基产生,从而引发HEMA 聚合,生成另外一部分沉淀,这两部分沉淀共同堵住牙本质小管,起到了脱敏作用。

A statistics in world range indicates that the Sr/Eu ratios in the peraluminous granites show similar variation trend to those in pegmatitic apatites. This paper suggests that the high Sr/Eu ratio (>300) in apatites or peraluminous granites is due to the strong partition of Eu〓 into the aqueous fluid, and this ratio can be used as an excellent geochemical indicator of fluid exsolution from magmatic melts.

对世界范围内的过铝质花岗岩统计表明,过铝质岩浆岩的全岩样品中的Sr/Eu也呈现二歧变化,由此本文提出Sr/Eu比值是指示过铝质岩浆体系中岩浆流体相出溶的有效地球化学参数,大于300的Sr/Eu比值是Eu〓强烈分配进入流体相的地球化学标志。
