种差异

Methods According to differences in internal transcribed space sequences of Penicillium genus and specific IAO sequence, we designed species-specific primers AS1/RS4 and IAO1/IAO2 of Penicillium griseofulvum and established the corresponding PCR systems.

Thus it was hypothesized that Chinese refusals and English refusals might on the one hand share something in common, but on the other hand would definitely distinguish from each other in respect of pragmatic principles due to the underlying cultural differences of these two languages; when Chinese learners of English as a second language perform the speech act in English, they might, more or less, demonstrate some interlinguistic characteristics which would distinguish their refusal production from that of either the Chinese natives or the English natives whereas resembling these two in some given aspects.

因此，本研究基于这样一个假设：汉语和英语在实施&拒绝&言语行为时会表现出一定的共同之处，但由于汉语和英语这两种语言各自所承载的文化之间的差异，使这两种语言在实施&拒绝&言语行为时所遵循的语用原则也表现出各自不同的特点；而中国的英语学习者在用英语实施&拒绝&言语行为时或多或少地带有语际语的痕迹，即既区别于汉语和英语母语者，同时又与这两者在某些方面有着相似之处。

Representational difference analysis of cDNA is a powerful technique for cloning the differentially expressed genes between samples. Kandelia candel and Dunaliella salina are two important halophytes.

If there is a difference, as the degree is different, the difference's influence on IC has 3 situations: neglectable, slightly important, very important.

若有差别，由于差别大小不同，它们在两种文化整体差异中所占的地位就不同，可以呈现出三种主要情况：不重要的，比较重要的，非常重要的。

As revealed by the voltage topographic maps and the tomographic mapping, the source location of the distinct N1 is in the occipitotemporal areas.

并且，与单纯形状知觉任务相比，图形形状和空间位置知觉任务表现枕颞区N2波幅的显著减弱，P3潜伏期的王著缩短，额区的P2波幅的显著减弱；(3)脑电地形图与高分辨率断层成象显示，两种任务的特征波N1成分均来源于双侧的枕颞皮层，表明两种任务均涉及到与物体形状识别相关的视皮层腹侧通路，而差别波dN2成分来源于左侧枕颞区，暗示特征加工的差异主要发生在左侧枕颞区。

Objective Facial paralysis is one of the most of important postoperative complications of parotidectomy. The aim of this paper is to study the correlation of different dissection of facial nerve and facial paralysis.

目的：面瘫是腮腺术后的重要并发症之一，作者通过研究腮腺手术的三种不同面神经解剖术式后的面瘫发生率的差异，探讨三种术式的优缺点。

Qualitative and quantitative analysis of chemical constituents.(1) Based on the GC spectrum of 2 species, Whitmania pigra and Poecilobdella manillensis shows little difference between them. 24 kinds of fatty acid in Whitmania pigra was firstly separated and determined by GC/MS. Among them, phenylacetic acid is a component which has active of anticancer. The existence of many unsaturated fatty acid provides chemical evidence for ShuiZhi's functions of invigorate the circulation of blood.

六首次对两种水蛭的脂肪酸类化合物进行了GC定性分析，发现其脂肪酸组成未见明显差异，后又对宽体金线蛭的脂肪酸类化合物进行了GC-MS分析，初步鉴定出24个化合物，包括苯乙酸、龙脑和22种脂肪酸，其中所含的苯乙酸具有抗肿瘤活性，大量不饱和脂肪酸的存在为水蛭在血液流变学方面的药理作用提供了一定的化学依据。

The ramet populations of the species at OSES and Inner Mongolia Grassland Ecosystem Research Station and those under conditions of monoculture and mixed with different species were compared.
