With a combination of botanical extracts , karate butter , and triple dna , it boosts cellular metabolism and works on the main factors that triffer skin aging 以植物萃取物、和三倍dna的组合,促进多孔的新陈代谢和主要因素防护皮肤老化。
Work surfaces tend to be porous to some extent , especially if they are ageing , and they may be covered with a biofilm that shelters bacteria 工作表面在某种程度上都是多孔的，特别是一些使用较久的，因而其上可能覆有保护细菌的生物被膜。
The layers from substrate to top of the deposited film are ti substrate , buffer layer ( interface between substrate and film ) , porous layer and lamellar layer 研究发现，从钛合金到羟基磷灰石共有四层结构：钛合金基体、钛合金的氧化层、多孔的纳米晶羟基磷灰石和花瓣状的结晶良好的羟基磷灰石。
Piston plated by 0 . 5 - 3u tin on the surface in chemical way , the tin layer with little hole has the lubri - cative quality of soft metal . it can absorb more lubricative oil to drop the friction between the piston and cylinder 在活塞表面用化学方法镀覆05 . - 3的锡层，多孔的锡层有软金属的良好润滑特性，能吸附较多润滑剂，降低了活塞与气缸音的摩擦功
All materials shall be structurally sound and appropriate for safe use . product durability shall be ensured by the use of corrosion - resistant metals such as stainless steel , and coatings such as zinc - plating , galvanizing , and powder - coating on steel parts , subject to the project - specific requirements below 具抗霉菌性，绝不会因霉菌而腐烂-网布是多孔的，在阳光下热气透过网孔而散发，达至散热功能-可抵受冰雹侵袭
The polystyrene particles with 2 . 8 micrometer mean diameter were prepared by dispersion polymerization and hollow porous micro - sphere were prepared by extraction after seeding emulsion polymerization . particles with multi - hollow structure were obtained and characterized by sem , additionally the mechanism and factor about formation of porous structure were also discussed . to prepare the biodegradable nano - particles , reversed - phase micro - emulsion and ionotropic gelation methods were used 利用分散聚合法制得了粒径约为3 m的聚苯乙烯种子微球，再通过溶胀、交联、种子乳液聚合及萃取处理，最后得到中空多孔的聚合微球，并讨论了其成孔机理和各博士论文功能型复合超微粒子的制备研究因素的影响。
It is shown that paraffin can be uniformly absorbed into the pore network of expanded graphite , that expanded graphite remains its vermiform structure in pcms , that the phase - change temperatures of composite pcms are similar to that of paraffin , and that the latent heat of composite pcms is are based on the mass fraction of paraffin in the composite materials 结果表明：膨胀石墨吸附石蜡后仍然保持了原来疏松多孔的蠕虫状形态，石蜡被膨胀石墨微孔所吸附；复合相变储热材料的相变温度与石蜡相似，其相变潜热与基于复合材料中石蜡含量的潜热计算值相当。
That is the premise of the bg / ha electrophoresis codeposition . the laws of the electrophoresis deposition of the bg and ha partic les were found by the study on each of their deposition under the different conditions . the electrophoresis codeposition of the bg and ha particles had been studied and the bg / ha graded coating , which is compact in the bottom layer and porous near the surface layer , had been prepared on the surface of the dental implant after the low temperature heat treatment ( about 740 ) and fast firing ( 50 - 80 / min , heat preservation time was 5 - 8min . ) 以bg微粉和ha微粉作为涂层原料，通过研究bg和ha微粉在非水介质中的分散情况和带电特性，选择冰醋酸为介质，使分散在其中的bg颗粒和ha颗粒表面均带上正电荷，为电泳共沉积提供前提条件；通过对不同条件下bg 、 ha各自电泳沉积的研究，探索出了两者电泳沉积的规律；通过对bg和ha在冰醋酸中电泳共沉积以及后续低温( 740左右)快烧( 50 ? 80 min ，保温5 ? 8min )热处理的研究，在钛合金牙根种植体基体上成功制备出了底层致密而表层多孔的bg ha梯度涂层。
Reaction - bonded sic was prepared by using melt silicon infiltrated carbon perform at 1500 c ; then evaporated the resist silicon at 1800 c for 2h in vacuum and the porous body of sic was attained . using melting mosi2 infiltrated sic body at 2050 c we got the desitive mosi2 / sic composite 将c质坯体在1500左右制得rbsc (反应烧结sic )材料，采用真空下1800脱除rbsc中的残余si的方法，获得了多孔的sic坯体，用mosi _ 2在2050直接浸渗坯体得到了致密的mosi _ 2 sic复合材料。
2 ) in the solutions with high hf concentration , the porous surface is formed on the multi - c subtracts . the reaction speed becomes slower with the decrement of hf concentration , which makes the surface rougher . ( 3 ) reaction mechanism the texturing process starts on " as - cut " multi - si wafers 2 )在高hf的溶液中，能够形成多孔的表面， hno _ 3的浓度不变，随着hf浓度的降低，反应速度较慢，郑州大学硕士学位论文摘要腐蚀的结构更加细化，均匀，粗糙，有利于光的吸收。
