查询词典 prevent changes

Pathological changes in biological tissues usually cause changes in their microstructure. Since the second harmonic generation signal is highly sensitive to the symmetry change of the microstructure , SHGI can be used for the early diagnosis of diseases and the monitoring of aftertreatment in clinics.

生物组织的病变往往会引起微观结构的变化，而二次谐波信号对组织的结构对称性变化高度敏感，因此二次谐波成像对于某些疾病的早期诊断或术后治疗监测，具有很好的生物医学应用前景。

To study the changes of plasma endotoxin NO and hemorheology in experimental cirrhotic rats and their correlation,we have used hemorheology analysis system and the means of limulus amoebocyte lystata assay Griess assay to detect changes of plasma endotoxin NO and hemorheological parameter in rats at 3 6 9 weeks after CCl4 administration.

为探讨肝硬化中血浆内毒素、NO水平的变化及血液流变学特性的改变及其相互关系，我们通过用四氯化碳(carbon tetrachloride，CCl_4)来诱导大鼠肝硬化模型，采用鲎试剂动态浊度法、镉还原比色法、血液流变学分析仪，分别检测了大鼠肝硬化演变过程中早期(诱导第3周末)、中期(诱导第6周末)、晚期(诱导第9周末)的血浆内毒素、NO水平及血液流变学各参数。

Studies on sequence changes in the early genomes of interspecific F_1 hybrid and amphidiploid in CucumisIn the present study,extensive genomic changes were detected in newly obtained allotetraploid of Cucumis,namely Cucumis hytivus Chen and Kirkbride,by AFLP analysis using 12 pairs of EcoR-I/Mse-I primers.

甜瓜属远缘杂种F_1及人工异源双二倍体早期基因组序列变化研究利用12对Eco RI/Mse I选择性引物，对甜瓜属人工异源双二倍体C.hytivus及其二倍体父母本进行AFLP分析，结果发现多倍体基因组在形成早期发生了广泛的序列变化。

We have found that there are regularity changes in the Raman spectra of grossular-andradite as the rise of iron in the crystal structure from grossular to andradite after studying of Raman spectra of grossular-andradite, that is to say, their peaks shift to low wavenumber; At the same time , there are some changes in the bond angles of O-Si-O and O-Y-O:the higher of iron contents, the evidenter of splitting of two wind vibration peaks of SiO4 tetrahedron and YO6 octahedron.

通过对钙铝榴石-钙铁榴石的拉曼光谱研究发现，从钙铝榴石到钙铁榴石，随着矿物结构中铁的含量的增加，他们的拉曼光发生规律性的变化，即所有的峰向低波数方向发生漂移；同时，由于铁含量的不同使得石榴石晶体结构中O-Si-O与O-Y-O之间的键角发生了一定的变化，在其拉曼光谱谱图上表现为铁的含量越高，[SiO4]四面体和Y-O八面体的两个弯曲振动峰分裂得越明显。
