Stone is from rock, and rock is consist of the mineral, the mineral contain iron is the source of the iron in stone products , iron element spread widely in natural world, but most of them appear to be compound, iron element is belong to medium activity metal, under high temperature is easily to be strongly acted with oxygen, sulfur, chlorine, and easily dissolve in abio-weak acid solution and strong hydrochloric acid solution, at the same time, the strong alkali solution also corrade the iron.

石材是岩石经加工后所产生的制品，岩石是由矿物组成的，其中含铁矿物是石材中铁质的来源。铁元素在自然界中分布甚广，但大多以化合物的方式出现，由于铁元素属中等活泼性的金属，在高温下易和氧、硫、氯等元素发生强烈反应，并易溶于无机稀酸和浓盐酸的溶液中，同时浓碱溶液也易侵蚀铁。

Results For the first primary lesions,most of them were stage IIa, including 12 invasive ductal caicinoma, 5DCIS, 2 invasive lobular caicinoma, a invasive carcinoma with cribriform pattern and 1 case mixed-cell carcinoma. On FFDM, 5 had microcalcification,13 were mass, 1 showed focal high attenuation and 2 were not detected. For the second primary lesions, most of them were stage 0, including 7 invasive ductal carcinoma, 12 DCIS ,1 invasive lobular carcinoma, 1 mixed-cell carcinoma.

结果；第一原发癌以Ⅱa期为主，浸润性导管癌12例，导管原位癌5例，浸润性小叶癌2例，浸润性筛状癌1例，混合细胞癌1例；5例以微钙化为主要表现，13例肿块，局部密度曾浓1例，2例未见异常；第二原发性癌以0期为主，浸润性异常癌7例，导管原位癌12例，浸润性小叶癌1例，混合细胞癌1例；11例以微钙化为主要表现，肿块3例，结构不良4例，局部密度曾浓1例，2例未见异常。

We used Critical Incident Technique to analyze the data on this research. By filling the half structured question paper from the sampling Hakka restaurants on Meinung, we collected the opinions of service encounter, and Hakka cultural experience from customers. Besides, we also collected the opinions of service encountr from waiters. Then we classify the question papers using two standards which are "Dramaturgical theory" and Bitner's standard developed by Bitner et al.

本研究采用关键事件技术（Critical Incident Technique，CIT），以半结构式的问卷、利用便利抽样方式搜集美浓地区客家餐厅服务人员与顾客对於影响服务接触与文化体验的关键事件之意见；以开放式的问卷利用立意抽样方式搜集美浓地区客家餐厅经营者对於服务接触与文化体验满意之关键事件的看法，再以「剧场理论」与Bitner et al。

This is due to the decrease in solid resin content, caused by their brightness and color hue to the sprasely jiashui of diltue, though, the face of it is in a State of stability and self-crimping polymer binders, once you have the role of epigene will make the segments structure extended until molecular break the business card printing and membership card produce ink film without gloss.

这是由于不流体树脂含量的裁减造不败的，由颜色色相的不浓抹到稠不浓，虽然增火后，暗不天看来处于安定笔直状况的矮不合子拆开料，一旦有内辛的功用会使链段布局扩张直至不合子断裂而使制卡和会员卡制作不不入的图文不朱膜操纵了平泽量）。

The characteristics of the AP include (1) in addition to the formation of hydrogel in aqueous alkaline or polar organic solution, AP can form carbonaceous hydrogel in neutral and acidic aqueous solutions, which extents the application of carbonaceous sol-gel;(2) AP contains a large amount of nitric groups which decomposes quickly by thermal initiation, releasing a large amount of gases and heat, indicating explosive properties of the AP;(3) metal salt-containing AP is also explosible by thermal initiation, and the metal in AP promotes the explosion.

以沥青为碳源，用氧化法制备水性沥青过程中，浓硫酸和浓硝酸的比例、用量、氧化温度及氧化时间对水性沥青的收率皆有影响。经过氧化后，沥青上含有许多含氧官能团，导致水性沥青溶于水。含氧官能团越多，水性沥青越易溶于水。调节制备条件，可使水性沥青不仅可以在碱性水溶液中形成凝胶，而且可以在中性和酸性水溶液中形成溶胶、凝胶，从而拓宽了炭基溶胶—凝胶法制备炭基纳米材料的应用范围。

New Orleans in okra hoosh is conducted on the basis of all sorts of change, including the most classic Creole type that with spicy Cajun style of soup.

新奥尔良人在秋葵浓汤的基础上进行了各种各样的改变，包括最经典的Creole式以至带着辛辣味道的Cajun式浓汤。

As for acetalation, we research the effects of acid kinds, acid quantity, temperature solvents on it and get the conclusions that the optimized acid is sulfuric acid, the optimized temperature is 65 °C, the reaction time is five hours, and the material ratio of sulfuric acid to methylglyoxal to methanol is 0.028:1:6.837.

在醛保护一步中，研究了酸种类、酸用量、温度及其溶剂的影响，得到了本反应的较好条件是：酸为浓硫酸，反应温度为65℃，反应时间为5小时，浓硫酸：丙酮醛：甲醇的配比为0.028：1：6.837，反应收率可达81%。

In this thesis,MWNTs were modified firstly using concentrated acid of H_2SO_4 and HNO_3,and then octadecyl isocyanate was grafted onto the surface of the MWNTs to improve the dispersion and the interaction between the filler and the matrix.
