The results show that there is intensive synergistic effect among cetyltrimethylammonium bromide, benzalacetone and polyethylene glycol. A bright and compact nanocrystalline zinc was produced due to the coexistence of such three additives.

结果表明，十六烷基三甲基溴化铵、4-苯基-3-丁烯-2-酮和聚乙二醇三种添加剂之间具有较强的协同作用，采用三者组成的混合添加剂可制备出光亮致密的纳米晶锌镀层。

The aberrant phenotypes were observed in the anther of tobaccotransformed with ZM401 sense construct: the inflorescence growth and floral axiselongation are suppressed; the flower buds falling or flowers abscission earlier wereobserved. The degradation of tapetum are not observed at the binucleate pollen stagewhich corresponds to the mature stage, although the tapetal cells of untransformedtobacco anther at the same stage have already degenerated completely anddisappeared.

对转基因烟草进行形态学、组织学分析结果表明，ZM401基因以反向方式整合的转基因烟草表现一切正常，而含有ZM401正义基因的转基因烟草在表型和组织学上都出现了异常：花序生长缓慢，花序轴变短，生长过程中花逐渐脱落，花序轴褐化枯死；花药绒毡层退化延迟，药室内壁在雄配子体发育后期不能进行带状加厚，阻碍了花粉粒的释放。

They all have the typical structure of leaf of C4 plant, but out of the ordinary is that the structure of the midrib is alike the parallel veins and there is a layer of fiber cells between the phloem and the bundle-sheath of vein in the midrib and big parallel veins while the outer wall of the bulliform cells is less cuticularized.

摘 要：以7个杂交狗牙根品种的叶片进行解剖研究，结果表明，各品种均具禾本科 C4植物叶片典型结构，其独特处是：中脉结构与平行脉相似；中脉维管束、平行脉大维管束的维管束鞘内侧韧皮部外有一层纤维细胞；泡状细胞外壁很少角化。

These features are very similar to those of the well-known PGE-rich Bushveld and Stillwater layered intrusions.

二、通过在粘土片层间组装有机硅的办法合成了一种全新的有机-无机杂化结构的中孔粘土材料。

Considering the shielding effects of carbonous layer forming on the burning surface on the transmission of external irradiation, the burning characteristics of 1040, 1041, N -5 and N propellants were analyzed.

考虑到辐射在燃烧表面上形成的碳化层对辐射传递的阻碍作用，本文分析了1040，1041，N-5和N型推进剂的燃烧特性。

Penicillin V acylase from the crude culture filtrate of Fusarium oxysporum FP 941 was purified with a single band on non-denaturing electrophoresis by means of (NH4)2SO4 fractional precipitation, adsorption on, and elution from, celite, ion-exchange column chromatography with DEAE-cellulose, and Sephadex G-200 gel filtration chromatography.

通过硫酸铵沉淀、硅藻土吸附、DEAD-纤维素离子交换层析和Sephadex G-200凝胶过滤，由尖镰孢FP941培养滤液中得到了聚丙烯酰胺凝胶电泳均一的青霉素V酰化酶。

Differing from the ancient and modern known palaeochannel-type exogenetic-epigenetic uranium deposits, Malinov uranium deposit has developed strong chloritization for several times.

俄罗斯马林诺夫铀矿床与已知古代和现代的古河道型外生后生铀矿床不同，它强烈发育不止一次的绿泥石化，且局部出现硫化物-硒化物化和碳酸盐化，古层间-潜水氧化发育的可靠标志表现弱。
