该营养土是由含氮、磷、钾和含有有机物质的有机质、腐殖泥炭土为基质，以珍珠岩、泡塑粒为填充料再加入其它配料制成的，其含有花卉培植所需养分，含量均比花泥高，具有疏松，透气性好，保水性较强，比重小，无臭味等特点，适于兰花、茶花、菊花、月季等多种花卉及阴生植物，盆景、盆栽柑桔等栽培需要。产品质量达到广东省企业标准报批稿的指标要求。

Distribution and Apparent Abundance of the Basking Shark, Cetorhinus maximus, off the Central and Southern California Coast, 1962-85

Basking sharks, Cetorhinus maximus, are frequently observed along the central and northwestern southern California coast during the winter and spring months. These large plankton feeding elasmobranchs, second in size only to the whale shark, Rhineodon typus, had been the subject of a small commercial fishery off California in the late 1940's and early 1950's for their liver oil, rich in vitamin A, and in later years for reduction into fish meal and oil (Roedel and Ripley, 1950). These fisheries were sporadic and did not take basking sharks in large numbers.

~(85)Zr核的高自旋态研究

利用102MeV的28Si束流,通过60Ni(28Si,2pn)熔合蒸发反应布居了85Zr核的高自旋态,测量了γ-γ符合及DCO比值,建立了一个有43条能级,75条γ跃迁的能级纲图,新增加了36条γ跃迁,25条能级.将能级自旋推高到(49/2+),首次观察到了转晕带的第二回弯.并确认了一条建立在17/2-负宇称带上的磁转动带.

~(85)Zr的高自旋态和磁转动带研究

<正>质量数80区的过渡性核表现了集体性和单粒子性的能级结构。对质子数Z为37～40、中子数N=45的原子核,如81Kr,87Mo核,在中低自旋时显示了单粒子特性,而在高自旋态时表现出较多的集体性。 近些年来,在过渡区在束γ谱学,如83Rb、83Y等核研究中,观察到了一串建立在较高K态的增强的△I=1的M1跃迁。它被认为是一种新的激发模式,叫做磁转动带。我们对85Zr的研究目的,一是将其能级推到更高自旋,另一个是寻找该核的磁转动带。
