The pathological formation of patches of gum on certain plants, such as sugar cane and some fruit trees, resulting from attack by insects, microorganisms, or adverse weather conditions.

流胶现象，流胶病某些植物上，如甘蔗及一些果树，形成胶质斑块的病理现象，由病虫害、微生物或恶劣的气候条件侵袭而引起

MgO thin films were successfully prepared on Si substrate by a novel and simple Sol-Gel method. The results indicated that collodion is a key element to form stable MgO sols. The structures of MgO films are closely related to the amount of collodion and the annealing temperature.

摘 要 以硝酸镁为起始原料，胶棉液为添加剂，在Si(100)衬底上成功地制备MgO薄膜，结果表明，胶棉液是形成MgO溶胶的关键组份；薄膜的晶体结构与胶棉液的含量及退火温度有关。

Based on present application status of waste products in curriery in China, the advantages and disadvantages of collagen and analysis and characterization of collagen extracted from hideoffals, studies on collagen application properties and its blend films with one or two polysaccharides were done in this thesis.

本论文基于我国制革废弃物的应用研究现状及胶原蛋白的性能优势与缺点，在减轻制革污染的同时，变废为宝，以高值转化为目的，在对从制革皮边角余料中提取的胶原蛋白进行分析表征的基础上，围绕胶原蛋白的应用特性和共混生物膜材料进行了研究。

To simplify Hu Ying and coworker's mixing model according to the gel's characteristics, and to revise the Flory's physical entanglment elasticity model, a concept of non-gaussian-short chains and interlooping chains is introduced which results, in a super-short and interlooping chains fraction Ψ and the number of effective segment N.

含离子凝胶分子热力学模型则在上述工作的基础上，进一步考虑了大分子网链中离子氛之间的静电排斥作用，并假设凝胶内活动离子的扩散作用服从唐南平衡，导出了新的含离子凝胶的分子热力学模型。

May take direct legal version, photoptic photoptic rubber selection dichromate or diazoresin, or salt produced directly from the market to buy diazoresin photoptic gum silk e-sensitive glue to make a number of strickle several times to version suitable for printing on thick.

可采取直接感光法制版，感光胶选用重铬酸盐或重氮盐进行配制，或者直接从市场购买重氮感光胶，在丝网上涂感光胶时尽量多刮几次，以适宜网印厚版。

In the food industry, locust bean gum and other food often plastic compound used as thickener, a liquid, adhesives and cementing agent.

在食品工业上，刺槐豆胶常与其它食用胶复配用作增稠剂、持水剂、粘合剂及胶凝剂等。

In the food industry, locust bean gum are often associated with other edible gum compound used as a thickener, holding agent, adhesives, and gelling agent.

在食品工业上，刺槐豆胶常与其它食用胶复配用作增稠剂、持水剂、粘合剂及胶凝剂等。

The results showed that the total dissoluble proteins hands of 8% and 10% gel were 91 and 97, respectively, and the seed salt soluble proteins bands of 10% gel were 69; All of the five alfalfa species have their own characteristic bands, which are different in number, distribution, width, and concentration; Among three methods, the five species' seed dissoluble protein fingerprints of 10% gel' bands is relatively more, which genetic diversity scattered in A, B and C regions, and can be repeated in different experiments. So it's the best fingerprint. The fingerprints of the seed dissoluble proteins and seed salt soluble proteins of five species are unanimous, which showed that: the hybrid has the nearest genetic distance with Medico go sativa cv.

结果显示：5/个种10%和8%凝胶电泳的种子可溶性蛋白总带数分别为97和91， 10%凝胶电泳的种子盐溶蛋白共有69条谱带；5种苜蓿在种子可溶性蛋白和盐溶蛋白电泳图上都具有各自的特征谱带，谱带数目、位置、宽窄和颜色深浅都存在明显的差异；10%凝胶的可溶性蛋白指纹图谱谱带数目相对较多，种间遗传差异在A、B、C区均有分布，谱带的重复性好，是鉴别种的最好图谱。5种苜蓿种子可溶性蛋白和盐溶蛋白指纹图谱一致，表明杂交种和敖汉苜蓿的谱带相似性最大。

Optical mouse lens system of the launch and the combination of components is one, fixed in the shell on the mouse, and the phototransistor is fixed in the circuit board, the location of the two must be very precise, manufacturers in the calibration of the location with hot melt adhesive to a fixed LED components in the lens, and if in use, the mouse has been touched or fall too much vibration, it is possible to make hot melt off, shift light-emitting diodes.

光电鼠标的发射及透镜系统组件是组合在一体的，固定在鼠标的外壳上，而光敏三极管是固定在电路板上的，二者的位置必须相当精确，厂家是在校准了位置后，用热熔胶把发光管固定在透镜组件上的，如果在使用过程中，鼠标被摔碰过或震动过大，就有可能使热熔胶脱落、发光二极管移位。
