The stable or unstable state of the montmorillonite-water dispersion is mainly effected by the properties of montmorillonite, water, and stabilizers as well as their interactions, while the type, the structure, the properties and the concentration of the stabilizer play dominate roles. Based on the molecular designing clues, this research selected three sulfonated copolymers as the stabilizers, i.e. the sodium 2-acrylamido-2-methyl-1propane sulfonate /acrylamide /disodium itaconate terpolymer, the AMPS/AM/N-vinyl pyrrolidone terpolymer and the sodium styrenesulfonate /IA copolymer. The preparation and characterization of the sulfonated copolymers were discussed, the high-temperature stability of the montmorillonitewater dispersion was characterized with the rheology, the filtration, the particle size distribution, the electrostatic properties, and the adorption of the sulfonated copolymers onto montmorillonite particles. At the same time, a systematic mechanism of the hightemperature stabilization of the dispersion was presented.

本文构筑了分子设计的思路，选取AMPS(2-丙烯酰胺基-2-甲基丙磺酸钠)/AM/IA三元共聚物、AMPS/AM/NVP三元共聚物和SSA/IA二元共聚物等三种磺化共聚物作为蒙脱土-水分散体系的高温稳定剂，进行了磺化共聚物稳定剂的制备与表征；从流变学、滤失性能、粒度分布、电性质以及磺化共聚物在蒙脱土上的吸附作用等方面，对蒙脱土-水分散体系的高温稳定性进行了研究，考察了蒙脱土-水分散体系的高温稳定性能，同时提出了高温稳定机理。

Diabetic gastroparesis is a diagnosis by exclusion and a delayed gastric emptying time on scintiscan. Patients with mild to moderate symptoms are often successfully treated with glycemic control, diet adjustment, and prokinetic agents. For severe disease, gastric electrical stimulation, gastrostomy for decompression and jejunostomy for feeding are other choices.

糖尿病胃轻瘫的诊断要排除机械性阻塞及其它原因，加上在核医影像上显示胃排空时间延长，依病情严重度，对於轻中度患者控制血糖、饮食调整、胃肠蠕动促进剂就有效果，严重患者考虑胃电刺激方式、甚至手术胃造口及肠造口以进行管灌饮食。

The apparent electron transfer rate constants kapp of azobenzcne to the underlyingelectrode are found to fall off exponentially with increasing the length of alkyl chain spacers. Theelectron tunneling constant P for the electron transfer in the present systenl are estimated to be1.35±0.20 per CH2 from the logarithndc k.p. versus n (nunther of methylenes in the alkyl chainspacer) plot.

而利用电化学活性的自组装单分子膜进行这方面的研究有其独到的优点，可以在分子水平上设计和改变电子转移距离以及电活性中心所处的微环境，为考察界面电化学的一些基本问题，例如电子转移速度与距离的关系、界面结构的影响等＊－q提供了较为理想

The mechanics parameters of marble, upper lherzolite, down lherzolite, granite and ore were tested by uniaxial compression testing and relaxation method of double torsion constant displacement load using Instron1342 type electro hydraulic servo test machine.

摘 要：利用Instron1342型电液伺服材料试验机，采用单轴压缩试验和双扭常位移松弛试验对大理岩、上盘二辉橄榄岩、下盘二辉橄榄岩、矿石、混合岩5组岩石的试件进行力学参数测试，获得相应的抗压强度、Ⅰ型断裂韧度等试验数据。

Then, we cloned the lipA and its partner gene lipB into the vector pUCPCM and pBBR22b both or separately. Therefore, we got 7 expression plasmids pBBR22blipAB, pBBR22blipA, pUCPCMlipAB, pUCPCMlipA, pUCPCMΔlipAlipB, pUCPCMΔlipA, pUCPCMΔlipB, and then electroporated them into B.

接着把lipA和它的伴侣基因lipB单独或全部克隆到载体pUCPCM和pBBR22b上，构建出pBBR22blipAB、pBBR22blipA、pUCPCMlipAB、pUCPCMlipA、pUCPCMΔlipAlipB、pUCPCMΔlipA、pUCPCMΔlipB七种表达质粒，通过电转化将上述表达质粒转化到含T7 RNAP的B。
