Results Ketoprofen calcium pectinate gel beads and calcium alginate gel beads showed excellent drug release pattern and mucoadhesiveness. Ketoprofen released from calcium pectinate beads mainly through diffusion behaviors, whereas the release of ketoprofen from calcium alginate gel beads was ruled by corrosion of carrier material.

结果 酮洛芬果胶钙凝胶小球和酮洛芬海藻酸钙凝胶小球均具有良好的生物黏附性能，果胶钙凝胶小球主要通过溶胀作用缓慢释药，而海藻酸钙凝胶小球的释药与凝胶小球慢慢吸水后骨架溶蚀有关。

以三聚氰胺和甲醛为原料制备MF气凝胶，在凝胶化过程中加入酚类化合物对MF体系进行改性，获得相应的湿凝胶，湿凝胶经超临界干燥，制备出密度为最低可达50 kg·m-3的酚改性MF气凝胶。

The process is composed of three steps: the formation of Ni_2 gel; the nucleation of nickel oxalate; the transition from Ni_2 gel into nickel oxalate sol.The nickel oxalate synthesized is identified by XRD to beα-NiC_2O_4·2H_2O with rhombohedron morphology, while two angles of the rhombus at underside are 106 and 74 degrees separately.

研究中，采用SEM、XRD、FTIR、TGA—DTA、GCMS等方法，对粉末样品进行表征。1凝胶—溶胶法制备单分散草酸镍粉末提出了一种凝胶—溶胶法制备单分散草酸镍的方法，由Ni_2凝胶生成—NiC_2O_4·2H_2O颗粒形核—凝胶Ni(OH_2向溶胶(NiC_2O_4·2H_2O)转化3个步骤组成。

The main component of cement is carbonate,a small amount of siliceous cement and iron cement.

胶结物的组分主要以碳酸盐胶结物为主，另有硅质胶结和少量铁质胶结。

The main reason why quarter-sawn board of Birch had smaller dry compressing shear strength than flat-sawn board of Birch in normal conditions was that Birch had different shear strength to the grain between quarter-sawn board and flat-sawn board. Meanwhile xylary rays in flat-sawn board were transversely cut and left a lot of pores in the flat-sawn board, so adhesive can enter these pores and turn into adhesive nail. While these pores provided a kind of tunnel for water, so cause this phenomenon that wet compressing shear strength of flat-sawn board of Birch was smaller than that of quarter-sawn board of Birch. The possible reason why quarter-sawn board of Oak had greater dry compressing shear strength than flat-sawn board of Oak in normal conditions was that ratio of springwood on quarter-sawn board and flat-sawn board was different.

造成柞木径切板的常态压缩剪切强度比弦切板的常态压缩剪切强度大的主要原因是，在径切板和弦切板上早材胶接的比例不同，径切板的胶合强度试件上早材胶接的比例相对少，而弦切板的胶合强度试件上早材胶接的比例比径切板的胶合强度试件上早材胶接的比例相对大，由于早晚材胶接过程中强度决定于早材，这部分胶接强度比较低，这就使得柞木径切板的常态压缩剪切强度比弦切板的大；同时在柞木弦径面胶接过程中由于实际胶接面积的不同也能造成弦径面上API胶粘剂与之形成的化学键的数量不同，这也是造成柞木径切板的常态压缩剪切强度比弦切板的大的原因之一。

First of all, these two standards in the test project and test methods for perfect more standardized, science, and coupled with the standard abouttwoweeks divisions, increasing differentiation of qualitative test (including infrared identification and chemical identification) by the main identification to enhance strict control formula control, part of the application to natural or other plastic impersonatea butylbenzoic stopple stopple quality, control and standardize butylbenzoic stopple market.

首先，这两个标准在测试项目和测试方法上力求更规范、科学，并结合标准按材料划分的特点，增加了鉴别定性试验，目的是通过鉴别试验加强主配方控制，严控部分掺用天然或其它胶来冒充丁基胶塞，控制胶塞质量，规范丁基胶塞市场。

Self-assembled nanomicelles of N -cholesterol succinyl O -carboxymethyl chitosan were prepared by probe sonication method. The amphiphilic property and the critical micelle concentration of CCMC were determined by fluorescence probe technique; the morphology and the size of CCMC self-assembled nanomicelles were analyzed by transmission electron microscopy and the dynamic laser light scattering.

以 N -胆甾醇琥珀酰基- O -羧甲基壳聚糖(CCMC，胆甾醇基取代度6.9%)为原料，在水溶液中通过探头超声处理制备其自组装凝胶纳米胶束，采用稳态荧光探针法考察临界胶束浓度，并通过透射电镜和动态激光散射仪检测胶束的形态大小。

For the reaction between divinyl sulfone and N-ethylethylene-diamine or N-methylpropane-1, 3-diamine , no cross-linking occurred when the feed ratio of A〓 to BB'〓 was 1/1. When the feed ratio of DV to NDA or NPA is 3/2, no cross-linking occurred too in organic solvents such as DMSO, DMF and NMP, while cross-linking does occur in water.

对于二乙烯基砜与N-乙基乙二胺或N-甲基-1，3-丙二胺的反应，当加料配比为1／1时，反应在水和有机溶剂中不会凝胶；当配比为3／2时，反应在有机溶剂中亦不凝胶，而在水中反应时，会经过一种&假凝胶&过程，并最终发生凝胶。
