Variety of amino acids in tea as many as 25 or more, which isoleucine, leucine, lysine, phenylalanine, threonine, valine, eight essential amino acids the human body in six.

茶叶中的氨基酸种类丰富，多达25种以上，其中的异亮氨酸、亮氨酸、赖氨酸、苯丙氨酸、苏氨酸、缬氨酸，是人体必需的八种氨基酸中的六种。

The IR spectra of polyisocyanate curing agent with different content of TDI trimer was measured and analyzed.

对不同TDI三聚体含量的多异氰酸酯固化剂的红外光谱进行了测定，采用偏最小二乘法对所得到的红外光谱进行分析，测定了多异氰酸酯固化剂中TDI三聚体的含量，该方法简单快速，结果可靠。

When the resulting nitro compounds was reduced over 5% Pd/C catalyst, the nitro phosphinic acids required more catalyst that the esters nitro phosphinic acid, and dinitro compounds required more catalyst than mono-nitro compounds in the case of all nitro groups completely changed into amino groups.

用5％Pd/C作催化剂，将上述硝基物还原时发现，次膦酸形成的硝基物比次膦酸酯形成的硝基物需要更多催化剂才能使硝基全部还原成氨基；二硝基化合物比单硝基化合物需要更多的催化剂。

In this study, an index evaluation system of itaconic acid was established according to the current situation of IA and the correlative laws in China. For the first time, a complete research on the IA production from this point of view was carried out, finding out the problems in the process of IA production, and then the project was advanced. All the research were begun with the data from laboratory and escalated to the industry scale. During the past three years, some of the work were applied successfully to industry.

根据现有衣康酸生产的现状和我国清洁生产相关的法律法规，建立了衣康酸清洁生产的指标评价体系，并以此为依据对现有衣康酸生产的工艺首次从清洁生产的角度进行了系统的研究，找出现有工艺中存在的问题，分析问题产生的原因，并提出衣康酸清洁生产工艺改进的方案，本研究沿着先从实验室研究规模入手得到相关的基础数据，再以此为依据逐步扩大实验规模直至在大规模生产中取得应用，通过三年的研究与实践，其中的多项研究成果已经在生产中得到应用，并取得了良好的效果。

Under normaltemperature condition,it can retard elongation,Promote tillering,increase leafnitrogen and sheath starch content,increase leaf tissue electric resistance andchlorophyll content,increase free protine content;under low temperature stresscondition,paclobutrazol has the ability to minify the permeability of leaf cellmembrance,maintain leaf tissue electric resista...

在常温条件下，多效唑具有延缓早稻秧苗的伸长生长，促进分蘖，提高叶片含氮量和叶鞘淀粉含量，提高叶片组织电阻和叶绿素含量，提高游离脯氨酸含量等方面的生理效应；在低温胁迫条件下，多效唑能够减小秧苗叶片细胞膜透性，维持叶片组织电阻以及延缓叶绿素含量和净光合速度的下降趋势，提高脯氨酸含量，减轻回暖后秧苗的外部伤害程度。

That if the process can produce much liquid phase during the sintering, and which can become into completely-crystal needle-shap or aborization or bar-shap calcium ferrite instead of glass in the cooling process; if the magnetite is interweaved by the caking into the melting corrosion structure, the granular structure or the eutectic structure instead of exiling in the massive isolation; if the mount of the poreis is little, and uniformitly distributing; if the grain is little; if the organizational structure is symmetrical, all of which can improve the quality of the sintering.

另外还归纳出有利于强度提高的工艺参数和操作制度。分析工业试验和水钢现行生产的矿物组成、结构表明，水钢烧结矿以他形晶磁铁矿为主，铁酸钙为主要的粘结相，多形成熔蚀结构、粒状结构和共晶结构，强度较高；而在台车边缘和表层，由于存在较严重边缘效应和点火温度较低，使该区域的烧结矿组织结构疏松，局部呈蜂窝状或薄壁大孔状，铁酸钙较少而硅酸二钙和玻璃质较多，形成骸晶状结构和磁铁矿连晶，强度较低，致使返矿升高。

In addition, compared with starting POMs, BET surface areas of the POM-containing porous composites have been improved in the different extents.

与母体多金属氧酸盐相比，复合材料的BET比表面积有了不同程度的提高，其中，微孔多金属氧酸盐的比表面积提高的幅度最大，为350～1000m〓／g。
