慢化

It is prepared from pentachluorobenzonitrile by using KF as fluoride to substitute chlorine in the presence of benzonitrile under high temperature. But owing to the low solubility of KF and rigor synthesis condition, and the parallel auxiliary reactions, the speed of reaction as well as the yield is very low.

五氟苯甲腈的合成开发以五氯苯甲腈为原料在较高的温度下用氟化钾做氟化剂，通过取代苯环上氯原子而得到的，由于氟化钾在溶剂中溶解度低，合成条件要求苛刻，反应速度较慢，同时存在有平行竞争副反应，因而反应收率较低，国内尚无厂家生产。

The changes of freezing point and super-cooling point of a series of PM vitrification solutions was investigated in the process of slow freezing at a ratio of 5℃/min. This experiment showed that the vitrification solution over 41% had not freezing point, while the vitrification solution under 40% had freezing point and could ice.

The research of both theories and practices of gridding in the dissertation shows that: Linear interpolation based on triangulation is simple computationally and fast, but its gridding results isn't smooth and its precision is low; Multiquardric method is also simple computationally with high precision and good effect, but its gridding is slow because it is based on global calculation; Minimum curvature method is fast with high precision and good effect, but its gridding quickly degrades over areas with sparse data control when grid spacing smaller than the actual grid spacing is used; Ordinary Kriging method is high-precision, but its gridding is slow because of large calculation; Inverse interpolation is a computationally fast, efficient and robust method with high accuracy and perfect effect, and its gridding results of different gridding orientations are basically identical. Inverse interpolation is suitable for thegridding of geophysical irregular data, especially for large-scale geophysical irregular data.

本文的方法研究和数据试验分析表明：基于三角网的线性插值法计算简单，速度快，但其网格化结果不光滑，精度不够；多元二次函数法计算简单，网格化精度高，效果良好，但它是基于全局计算的，计算速度较慢；最小曲率法计算速度快，网格化精度高，效果良好，但其在稀疏控制点的网格化容易出现振荡现象；普通克里格法网格化精度高，效果良好，但其计算量较大，一般计算速度慢；反插值法网格化计算稳定，速度快，精度高，效果好，而且在网格化方向不同的情况下其网格化精度效果都达到基本一致，适合于地球物理不规则分布数据的网格化，特别是大规模地球物理不规则分布数据的网格化。

To investigate the pitting and metastable pitting rules of type 304 stainless steel, potentiodynamic polarization method was employed to study the behavior of metastable pitting and stable pitting on 304 stainless steel in sodium bromide solution and borate/phosphate buffered bromide solutions. The influence of the concentration of Br-、the pH value、the buffer capacity and general environmental factor to pitting potential and metastable pitting was studied as well.

Shen Kai: Should say the amount drops, before two years my statistic crosses China to have alliance of more than 500 advertisement, should say now 100 was less than, but change with mainland on, our product is spending competition with mainland all the time, be being clicked so e.g. the advertisement of Google is enclothed in former window, we fell hard with all possible means last year anew the window yielded, this is a very big innovation to the experience of the user, the 2nd, it is we undertook distensible to the font of Chinese, can read a gender to increase greatly, the 3rd is a lot of people complain Fu Meiyuan check is slower, we are OK last year immediate telegraphic money order, still can a lot of will be improve henceforth, we are change in ceaseless mainland.

沈恺：应该说数量是下降的，在两年前我统计过中国有五百多家广告联盟，现在应该说一百都不到了，但是和本土化上，我们产品一直在和本土化竞争，比如说Google的广告原来点击是在原窗口覆盖的，去年我们多方努力下从新窗口产出了，这对用户的体验是一个很大的创新，第二个，就是我们对中文的字体进行了扩大，可阅读性大大增加了，第三个就是很多人都抱怨付美元支票比较慢，我们去年可以直接电汇，今后还会有很多改进，我们是在不断的本土化。

DDS was used as test drug for determination of acetylator phenotype employing HPLC.The results showed that both the occupational and non-occupational exposed group were predominantly slow acetylators(52.2％and 45.5％),higher than that in the exposed controls(13.0％)(0 05).The risks for bladder cancer with the slow ace...

结果表明。无论有无2－萘胺职业接触史，膀胱癌病人中慢型乙酰化者所占比例（52.2％和45.5％）均高于对照组（13.0％），且差异有显著性（P＜0.05），比值比0R分别为5.56（95％可信限＝1.02～30.3）和7.25（95％可信限＝1.70～30.3），提示慢型乙酰化者若暴露于2－萘胺更易患膀胱肿瘤，乙酰化慢表型是膀胱癌的一个遗传易感因素。

银杏的不同器官和组织都能够诱导出愈伤组织来，其中，子叶和胚轴10d左右全部愈伤化，诱导速度和诱导率均最高，根则很难诱导，愈伤组织很少，褐化很快；叶片诱导的愈伤组织，生长慢，褐化也慢，在培养基上保持两三个月而不褐化；胚乳的诱导时间也较长，需要30d左右。

In the tune "the old city" represents Beijing, the music take the Peking opera as the source material, will divide the slow movement and the musical beat two parts, the slow movement sub-system will be persuasive the exquisite Peking opera melody to further process, causes it music, has displayed the urheen timbre delightful gentle performance special skill, will listen both to express feelings, the Beijing style to be full exquisitely, and will not lose the sonorous powerful place, music mood fluctuation repeat swings, the change will be careful, musical beat partial melodies sprightly smooth, by the urheen continuously the fast figure and the clear bright timbre, will entrust with this section of musics fresh and the active characteristic, but long will draw out a syllable appearance, also will then cause it alone lyricism, this music from differentThe angle expresses thinks of the ancient exquisite feeling, takes to the people infinite province to think with recalls.
