Results Cuticular papillates,glandular hairs,peltate scales,and non-glandular hairs presented on the leaf epidermis of C.paliurus.Anomocytic stomata were confined to the lower epidermis.Large cluster crystals existed in the uppermost layer of palisade cells.Midrib included one closed vascular system and one additional vascular strand.Secondary veins are semicraspedodromous and form marginal loops,tertiary veins are percurrent,quaternary veins form orthogonal or polygonal areoles filled up by branched and freely ended veinlets.

The ma er in, which large portio of it protein chain are arranged is referred to as tertiary structure.

蛋白质链中大链段的排列方式称为蛋白质的&三级结构&。

The quantitative structure-activity relationships were established based on the 1-octanol/water partition coefficient and an electronic parameters-lowest unoccupied molecular orbit. The result shows that the highest sensitivity is cell density between three end points, and the toxicity of secondary and tertiary propargylic alcohols is correlation to the position of alkynyl and hydrophobicity, respectively.

本次实验结果可发现三个参数中以Final yield的敏感度是最高的，而二级炔丙基醇类之毒性高低是和其炔基接的位置有一定的关联性，三级炔丙基醇类之毒性则与疏水性的高低有关：疏水性越高其毒性越强。

Closed-system algal toxicity test was applied to evaluate the toxicity of secondary and tertiary propargylic alcohols to Pseudokirchneriella subcapitata. The effects of propargylic alcohols were evaluated by three kinds of response endpoints, i.e., dissolved oxygen production, cell density, algal growth rate.

bstract：本研究以藻类（Pseudokirchneriella subcapitata）利用BOD瓶进行一密闭式系统之毒性试验，使用溶氧变化量，藻细胞的数量变化，以及以藻类细胞密度变化量计算所得的生长率三个终点，评估二级以及三级炔丙基醇类之毒性，藉由Probit模式求出半致死浓度（50% Effect concentration，EC50）。
