磷灰石組 的英文怎麼說
中文拼音 [līnhuīdànzǔ]
磷灰石組
英文
apatite type-
One of the most common bone substitutes used in clinic is polymethylmethy aery late ( pmma ). pmma can be described as an alloplastic, synthetic, nonbiodegradable polymer which has considerable versatility. however, a common problem associated with the application of pmma is the loosening
以有機玻璃作為母相，摻入一定比例的羥基磷灰石（ ha ）粉末，是一種較為有效的改善生物活性的方法，因為羥基磷灰石是人體硬組織的一種無機組分，與骨組織有良好的相容性和親和力，能誘導其周圍骨組織的生長。Bioactive substance such as hydroxyapatite ( ha ) and bioglass are coated on their surfaces in order to improve the bond between the implants and bone tissue
為改善其植入后與骨組織的結合，常在其表面塗覆一層具有生物活性的物質，如羥基磷灰石和生物玻璃等。Ha possesses well biocompatibility, which has been discovered through test and in clinical application. however, the relatively large dissolution or resorption rates of ha will result in the failure of the implants. fluoridated hydroxyapatite ( hfa ) in whose structure f " occupies partially the position of oh " in ha, is expected to be more resistant to body fluid and less soluble than ha and still possess almost the same bioactivity as ha
生物活性羥基磷灰石薄膜（ ca _ （ 10 ） （ po _ 4 ） _ 6 （ oh ） _ 2 ， ha ）廣泛地應用於鈦合金硬組織種植體表面改性，臨床應用發現ha薄膜具有很好的生物相容性，但是ha薄膜在體內溶解速度有時可能會過快，引起種植體在體內失效，因此， ha薄膜長效性方面有待于提高。Effects of pig slurry and phosphatic fertilizer on organic - p fractions and their availabilities
豬糞和磷肥對石灰性土壤有機磷組分及有效性的影響It is discovered that artificial skull is marinated in simuted body fluid : the sample surface like - boneapatite belongs to carbonic acid hydroxide apatite, which can have good combination with human body orginzation
而且試樣表面生成近似球形或片狀的類骨磷灰石，屬于與人體組織具有良好結合的碳酸羥基磷灰石。According to the rehydration characteristics of dehydrated phases, a kind of new cementious material system can be prepared with gypsum and fly ash
根據水泥水化產物脫水相具有再水化能力的特點，結合粉煤灰、磷石膏等礦物材料的化學反應特性，組成一個新的膠凝材料體系。His group began working to develop agents to target hydroxyapatite six years ago, but efforts were stalled by the inability to manufacture large quantities of the agent
他的研究組在6年前就開始尋找這個顯示羥磷灰石的試劑了，但是由於沒有能力大量製造此造影劑而被迫停止。Then by methods of fractionation of inorganic and organic p in soils and multivariate statistical analysis, this paper discussed phosphorus fractions in soils with three fertility levels and in different soil layers. the affecting factors on fast - available p ( avail. p ) were also related
在此基礎上，用無機磷分級和有機磷分組方法、多元統計分析的方法，研究了石灰性土壤不同肥力與不同土層中磷素的各種形態含量差異以及影響速效磷的因素，結果如下： 1Macrophages or osteoclasts can heighten the consistence of hydrogen ions in part circumstance contacted with material or interior cells by chemical reaction, which can accelerate the degradation of the material. secondly, calcium ion and hydrogen ion were the prerequisite raw material of bone formation. and bounds of calcium ions and hydrogen ions produced by the degradation of material provide the activity of osteoblastics affluent material basis, which accelerated the formation of new bone
實驗結果證明植入材料是以磷酸三鈣（ - tcp ）為主晶相，同時含有焦磷酸鈣、羥基磷灰石、無定形磷酸鈣晶相和非晶相，其化學組成與骨骼的無機礦物相組成相近，而且具有與骨骼相似的多孔網狀結構。Hydroxyapatite ( also called as hap below ) as the basic mineral component in man and animal bone play an important role in clinical medicine
羥基磷灰石是人體和動物骨骼的基本組成，在臨床醫學應用中，具有重要意義。分享友人
