凝胶

Unfortunately, it is very difficult to get good images of tracks in the aerogel tiles while they are still in the flight tray (as many of you have pointed out).

不幸的是，由于凝胶块还在收集器的盘子里所以很难得到轨迹在凝胶中的好图像。

The carbonaceous alcosol and the silica alcosol were prepared respectively by using aqua-mesophase and tetraethoxysilane as starting materials. Then the two alcosols were mixed and dried in open air and under supercritical fluid conditions to form binary carbonaceous-silica xerogel powders and aerogel powders respectively.

Based on the comparison analyses of the viscosity method, transition pressure method, visco-elesticity analogue and residual resistance factors as well as the application range, a series of technical methods and testing standards to evaluate the gel strength and properties have been set up and also the classification indexes of the gel has been established.

通过对粘度法、转变压力法、粘弹性模量法和残余阻力系数法等优缺点和实用范围的对比分析，建立了一套评价凝胶强度、性能的技术方法和测试标准；确定了凝胶分类指标。

The approach of preparation method is that, first, blend yttria into hot aquafortis, add silicone grease chemical compound after reaction, cool it to form gel. Second, heat the gel for 1-48 hours to acquire solid fruitage. Third, igloss the fruitage in reducing gas for 1-48 hours. Forth, add anorg and then igloss it in reducing gas for 1-48 hours in the temperature between 800-1600 degree.

它的制备方法，包括以下步骤：1将氧化钇溶入热浓硝酸中，反应后加入硅酯类化合物，恒温形成凝胶；2凝胶加热1-48小时，得到固相产物；3在还原气氛中灼烧1-48小时；4加入无机盐，在800-1600℃范围内，还原气氛中灼烧1-48小时；5稀酸洗涤，干燥后得到稀土激活Y2SiO5荧光粉。

The purity of refined Auricularia auricula water-soluble polysaccharides was checked by gel filtration chromatography of Sephadex G-200 and gel permeation chromatography.

凝胶色谱Sephadex G-100和凝胶渗透色谱法检验得到的峰形都为单一对称峰，表明得到纯度较高的黑木耳多糖AAP3-1。

To achieve the photoresponse to the UV,the functional groups of photoisomerization of azobenzene were copolymerized into the structure of the hydrogels in this study.

为此，本研究尝试通过将具有光异构化作用的偶氮苯基团键入高分子凝胶分子结构中，实现凝胶对紫外光的响应性。

Using IPG-DALT method, electrophoresis provide belier analysis for the lens protein separation, but the data repeatability should be further improved.

用IPG-DALT的方法，综合小样本量和低密度凝胶电泳与大样本量高密度凝胶电泳结果，可以更好地分析晶状体蛋白的分离效果，但重复性还有待进一步提高。

The preparation of two series of pH and temperaturesensitive hydrogels with different amounts of carbonyl group was described.

描述了含不同羧基量的两个系列的pH及温度敏感水凝胶的制备方法。所得的凝胶在37℃和pH1.4条件下不溶胀，而在37℃pH7.4条件下则溶胀。

However, the biggest difference between them is that polymer gels is chemistry association and hydrophobic associating polymer solution is physics association, and the intension of molecule chain coupling between them is different, too.

建议对疏水缔合聚合物溶液进行特性评价时应该同时结合HPAM溶液和聚合物凝胶溶液特性评价方法，开展深入的疏水缔合聚合物溶液与聚合物凝胶的对比研究工作。

When chymotrypsin was immobilized inthe gels, the stability of the immobilized enzyme is much raised when compared withthe free enzyme.

当把糜蛋白酶固定到这些水凝胶中时，与自由酶比较，固定化酶的稳定性有了很大提高，而且由于水凝胶的温度敏感特性，酶的活力在30℃和4O℃表现为"开"或"关"。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
