normal sulfate 中文意思是什麼
normal sulfate
解釋
正硫酸鹽, 中性硫酸鹽-
Furthermore, the wing imaginal disc clonal analysis showed that in the homozygous sll mutant clones, the extracellular wg was dramatically reduced. the reduction of extracellular wg indicated that the wg signaling in the wing imaginal disc was disrupted. the reason leaded to this phenomenon is that sll encodes a paps transporter, so the disruption of the sll gene would generate the unsulfated heparan sulfate proteoglycan ( hspg ), which most likely would lose normal function
進一步結合運用flp - frt系統和minute ~ - ，用缺損myc蛋白的表達來標記純合的sll突變基因克隆，用minute ~ -來相對的擴大含sll突變基因的克隆，對翅成蟲盤所作的克隆分析表明，在含sll突變基因的克隆中，細胞外的wg蛋白分佈明顯減少，這種細胞外的wg蛋白減少表明在翅成蟲盤中wg信號傳導受到了明顯抑制。 -
For concrete structure in the practical engineering, the non - mechanics damages, such as alkali - aggregate reaction, sulfate attack, carbonization, steel rust, freeze and thaw, and so on, are unavoidable due to the exist of erosive media. the deterioration form of mono or multi - factor influences on the concrete property of construction and durability greatly, and shortens the service life of the concrete to a large extent. permeability of concrete is the most important factor for these non - mechanics damages, so the permeability test of concrete is the normal and required item to study the durability of concrete
實際工程中的混凝土結構，因侵蝕性介質的存在而使非力學破壞行為無處不在，這些非力學破壞行為包括堿集料反應、硫酸鹽侵蝕、碳化、鋼筋銹蝕、凍融等，單一的破壞形式或多形式的復合破壞作用對混凝土結構性能及耐久性能均有著較為嚴重的影響，在很大程度上縮短了建築物的服役年限，而這些非力學破壞在很大程度上取決于其滲透性，所以測試混凝土滲透性能是研究判斷混凝土耐久性的常規必測項目。 -
As far as the durability concerned, the resistance of sulfate attacks of the normal concrete could n ' t compared with the hpc
耐久性方面，普通強度混凝土的抗硫酸鹽性能要比高性能混凝土差。
