In this paper , monolayer , microemulsion and biomolecule were selected as the template to induce crystal growth of calcium oxalate . the effect factors of them were discussed 本文分别选择单分子膜、微乳液、生物分子作为模板诱导草酸钙晶体生长，并探讨了促进和抑制草酸钙晶体生长的因素。
The nucleation and growth of calcium oxalate ( caoxa ) crystals in liposome solutions was investigated using laser light scattering spectroscopy and transmission electron microscopy ( tem ) 采用激光散射仪和透射扫描电子显微镜分别研究了卵黄卵磷脂( pc )囊泡的粒径和囊泡中生长的草酸钙晶体的粒径大小。
Calcium and magnesium ion are naturally contained in tap water and when sodium oxalate powder is added into tap - water , the reaction will generate white sediment of calcium oxalate . filter can remove such ion 真相剖析自来水中含有天然钙镁等离子，加入草酸钠粉末，反应生成草酸钙白色沉淀物，滤水器可去除上述离子。
Some reflective bright lines just like the edges of the polygon can be seen in the surface of starch grains while prisms of calcium oxalate can be seen in the parenchyma tissue , which have n ' t been reported before 显微特征上，发现单粒和复粒淀粉粒表面有时可见类似多边形边缘的折光率较强的亮线，薄壁组织中可见草酸钙方晶，以往文献中未见记载。
If the mixed films were used to study the formation of calcium oxalate crystals in fluid subphase , we can further understand the mechanisms of the formation of calculus crystallite at the cellular surface of urinary tract 所以，如果将实验设计成在流动体系中用磷脂和蛋白质的复合膜诱导草酸钙晶体形成，将能更贴近地了解草酸钙结石在尿路表皮细胞上的形成病理。
Various kinds of crystals were detected from urinalysis including calcium oxalate , amorphous phosphate , triple phosphate and uric acid in 83 patients ( 37 . 9 % ) of the urinary calculus group and 13 patients ( 12 . 6 % ) of the non - calculus group 同时，我们发现在83位（ 37 . 9 % ）尿路结石病患及13位（ 12 . 6 % ）非结石病患的尿液中存在著各类结晶体，包括草酸钙、无定形性磷酸盐、三重磷酸盐及尿酸结晶体等。
Studies on the biomineralization of calcium oxalate crystals were performed in vitro using monolayer film and langmuir - blodgett film as templet . sem , esem , tem , afm , xrd and ft - ir were used to characterize calcium oxalate crystals obtained from a series of experiments 以单分子膜和lb膜作为模板，用sem ， esem ， tem ， afm ， xrd和ft - ir等表征方法，在体外研究了草酸钙晶体的生物矿化过程。
As the reaction time and standing time increase , the percentage of calcium oxalate trihydrate ( cot ) decreases and the percentage of the thermodynamic stable calcium oxalate monohydrate ( com ) increases . the metastable calcium oxalate dihydrate ( cod ) is not observed 随着反应时间和陈化时间的增加，三水草酸钙( cot )直接转化为稳定态的一水草酸钙( com ) ，而没有经过亚稳态的二水草酸钙( cod ) 。
The major composition of crystals is calcium oxalate , it crystallizes with very different crystallization kinetics , e . g . monodinic monolydrate ( com ) , tetragonal dihydtate ( cod ) and triclinic trihydrate ( cot ) . com is easy to form urinary stones because it has stronger affinity for renal tubule cell membranes than cod , cot 其中，晶体的主要成分是草酸钙，主要有三种类型：一水草酸钙( com ，单斜晶系) ，二水草酸钙( cod ，四方晶系) ，三水草酸钙( cot ，三斜晶系) ，其中com与肾小管表皮细胞黏附力最强，是草酸钙型尿结石的主要成分。
Chondroitin sulfate a ( c4s ) , as a kind of endogenetic urinary macromolecule , not only increased the supersaturation of cac2o4 in solution , but also inhibited the two - dimensional growth and aggregation of com crystals . the growth of calcium oxalate crystals was influenced by surface pressure beneath dppc monolayer film . there were some crystals which have the same appearance as com crystals obtained from pure water system when monolayer surface pressure was hold 1 , 10 and 30 mn / m while those growth at 20 mn / m were perfect orderly induced by dppc monolayer 生物大分子c _ 4s作为一种内源性的尿大分子，它不仅从热力学上提高ca ~ ( 2 + )在尿液中存在的浓度，使体系中cac _ 2o _ 4保持较高的相对过饱和度，降低草酸钙结石成核的可能性；而且在晶体生长时，抑制com晶体晶面的二维生长和晶体聚集。
