And the corresponding chiral tertiary propargylic alcohols were obtained with enantiomeric excesses of up to 86%, which provided a simple, practical and inexpensive method to generate chiral tertiary propargylic alcohols.

经过筛选、测试，发现一β-磺酰胺基醇-钛复合物可在温和条件下，有效促进炔基锌对简单非活化酮的不对称加成，并且得到相应的手性三级炔丙醇，ee值达到了86%。

The ability of acne treatment was performed by inhibition of Propionibacterium acne and Staphylococcus epidermidis, which commonly isolated from pustular acne lesions.

结果发现乳清、肽类、醣类、菌之胞内萃取物均对铜离子产生螯合能力，显示克弗尔具有明显之抗氧化活性。

The somatic hybrids usually showed specific bands and combined all the bands of both parents. In combinations, some new bands were detected, and occasionally specific bands of parents were lost, which indicated that chromosome recombination and exchange happened after fusion. Additionally, in some combinations, specific bands from leaf parent were detected, which revealed the plants were of putative hybrid origin, because leaf protoplast cannot redifferentiate by both single culture and co-culture.

体细胞杂种一般表现为具有双亲的特征带，且综合双亲的所有带，但在部分杂种中检测到了双亲都没有的新带，也发现有丢失亲本的特征带或共有带的现象，说明融合后染色体发生了重组和交换；有的引物只检测到叶肉亲本的特征带，根据柑橘叶肉细胞无论单独培养还是共培养均不能再生的事实，可推测其为体细胞杂种或二倍体叶肉亲本型胞质杂种。

EyelinkⅡis used in experiment 3 to study the external and internal refence fame inmental rotation. The result is that presenting a number with an external referenceframe, subjects\' internal reference frames can be revised. At the same time, thesubjects tend to use frame rotation.

研究四的两个实验分别采用了汉字数字与阿拉伯数字以及经典的心理旋转的三维立体图形探讨了心理旋转中的表象表征与命题表征的转化，发现表象表征的容量组块是4，在4以下时，表象表征占主导地位，心理旋转采用表象的匹配，但在容量组块超过4时，命题表征的优势显现了出来，对于刺激物的整体加工的效果更为明显。

A clinical revelant ARDS model was induced in 12 dogs of either sex under pentobarbital anesthesia by Ⅳ injection of oleic acid0.08-0.1ml/kg.

结果发现，肺解除血中微聚物的功能受损发生在呼吸功能(PaO_2)受损之前，同时血中白细胞及血小板急剧减少。

In our previous studies, we explored that both protocatechuic acid and the aqueous extract of its original plant, Hibiscus Sabdariffa, showed strong inhibitory effects on the negative charge increasing of protein moiety in oxLDL and on the lipid peroxidation of lipid moiety in oxLDL. At present, we further investigate the effects of PCA and HSE on LDL oxidation.

在先前的研究中，我们已经发现原儿茶酸和洛神花水萃取物对於氧化型LDL所表现的负电荷增加及脂肪酸氧化有抑制氧化的作用，在本实验中我们以PCA和HSE进一步探讨其对抗LDL氧化的作用强弱。

Based on the analysis of the contents of Cu, Pb, Mn, Zn, and Cr in the rhizosphere sediments of Phragmites australis and Scirpus mariqueter at tidal flat in Changjiang Estuary, the following conclusions can be drawn.

长江口滨岸潮滩芦苇与海三棱草根系、茎叶以及根际沉积物中Cu、Pb、Mn、Zn、Cr的含量分析发现，Cu、Pb、Zn、Cr在根系中的含量较高，而Mn在茎叶中的含量达到总量的55%以上。

A series of mono-, sesqui-, di- and tri-terpenoids with various structural types, which produced by bio- oxidation, hydrogenation, hydrolyzation, esterification and cyclic cleavage toward-limenone, were analyed by GC-MS.

经GC-MS分析发现该两细菌对-柠檬烯有显著的生物催化转化作用，能对底物进行不同程度的氧化、还原、水解、酯化、开环等反应，并产生丰富的系列结构不同的其它萜类化合物：包括单萜、倍半萜、二萜、以及三萜等。

The results also showed that poly or and poly have better amplictiaon and polymorphism than other primers in setaria genomes.

研究发现AG，GA和CA重复的引物在狗尾草属植物有较好扩增，且多态性强。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
