Focusing on the problems existing in the implementation of polarity crosscorrelation"zero-crossing"algorithm in the practical applications, an improved approach based on HSI (High-Speed-Input channel of MCS8098) is proposed, which makes the circuit much simpler. Experimental results indicate that higher response speed and higher accuracy rating of signal recording can be obtained with the improved approach.

针对极性相关测速"零点穿越"算法在实际实现过程中存在的"零点穿越"信号容易"漏记"，而对流速测量造成不利影响等问题，本文提出了一种基于HSI的极性相关测速的技术改进措施，硬件结构更加简单；通过实验验证，基于HSI的极性相关测速法的响应速度快，信号记录的准确率高，是一种简单有效的技术方案。

The process of the removal of a apolar molecule or the hydrophobic moieties from water can be considered as two steps: One is the destructuring of the water in the vicinity of the surface of the solute molecules, and the other is the cavity holding the hydrocarbon molecule collapses.

非极性分子或极性分子的疏水部分从水中逸出的过程可视为由两部分组成：一是非极性分子周围的水分子的有序排列结构被破坏；二是水中容纳非极性分子的空穴倒坍。

The above results were interpreted by the calucation of CNDO/2 method of quantum chemistry. The effection of a collector-accelerating-agent mixed with a just main-collector was better than that of two collectors mixed. The structure of collector-accelerating-agent is described:① a carbonic chain or ring compound with a polar-radical,② a larger positive electric centre in this polar-radical〓 was the compound with many coordination atomics.

量子化学CNDO/2方法计算验证了上述结果，并且得到如下结论：选择有效的捕收促进剂与适当捕收剂混用，比用两种捕收剂混用更有效；并总结出捕收促进剂的结构特点为：①带一个极性基团，有足够疏水性的碳链、环化合物；②极性基因中有一个较大的正电荷中心；③极性基因中最好有多个能参与配位的极性原子。

One challenge is the changing definition of bipolarity."What we have seen over the past few years is the expansion of the bipolar spectrum," said Dr. Sharma. It may be helpful to look at unipolar depression and bipolar disorder as opposite ends of a continuum, rather than distinct diseases, he added.

面临的挑战是双极性定义的改变，Sharma博士指出，我们回顾这几年来，双极性异常所涵盖的范围越来越广；他附带表示，将单极性忧郁与双极性异常视为光谱的两端，而不是完全不同的疾病，可能是有帮助的。

Another feature of electrolytic CAPACITOR s, both aluminium and tantalum, is that most of them are polarized and require a DC bias for correct operation - a reverse bias may do damage and will certainly increase leakage (unpolarized electrolytic CAPACITOR s, which may be biased in either direction, do exist but they are uncommon, and considerably larger than the polarized variety).

电解电容还有一个特点，那就是绝大多数都是有极性的，其两端必须施加直流电压才能正常工作。如果极性接反，电容就可能损坏，其漏电流也会增加。无极性电解电容虽然已经问世，但是相比之下不常用，而且外形尺寸也比有极性电容大。

We build our basic Chinese polarity lexicon base on some existing Chinese and English sentiment lexicons. In the same while ,we also build domain lexicon、domain polarity lexicon、dynamic polarity lexicon、network polarity lexicon、privative lexicon、degree adverb lexicon.

我们在已有的中英文极性词典的基础上构建了中文基础极性词典，同时还构建了领域词典、领域极性词典、动态极性词典、网络极性词典、否定词典、程度副词词典等。

Bipolar II Disorder involves Major Depressive Episodes and Hypomanic Episodes. Since a significant portion of those suffering manic depression did not have full manic episodes, the classification was divided into Bipolar I and Bipolar II. However, Bipolar II is often a first step to Bipolar I. Over 5 years, between 5% and 15% of those will Bipolar II will change diagnosis to Bipolar I. Approximately 0.5% of people will develop Bipolar II in their lifetimes.

双极性二型包含重度忧郁症和轻躁症的症状由於有一大部份的躁郁症病人并没有完全的躁症症状，所以躁郁症要分为双极性一型和双极性二型然而，双极性二型常是双极性一型的第一步，经过五年，5% and 15%的双极性二型的病人会转变成双极性一型双极性二型的终生致病率大约为0.5

From the photophysical behaviors of 1, 3, 4-triaryl-2pyrazoline compound (TPP16) at low temperature, it can be considered that the twisted configuration between pyrazoline ring and the non-substituted phenyl group on the position 1 is the fluorescence configuration of conjugated system Ⅰ, and the twisted configuration between pyrazoline ring and P-nitrobenzene group is fluorescence configuration of conjugated system Ⅱ.

研究了1，3，4-三芳基-2-吡唑啉化合物TPP16在低温时的发光情况，发现：在低温77K下，共轭体系Ⅰ(苯基-N1-N2＝C3-苯基)在非极性溶剂中不发荧光，在极性溶剂中有较强荧光发射；而共轭体系Ⅱ(N1-N2＝C3-C4＝对硝基苄叉)在非极性溶剂或极性溶剂中均有荧光发射，表明N1所联取代基与吡唑啉环相扭曲的构象是共轭体系Ⅰ的发光构象，而对硝基苄叉与吡唑啉环相扭曲的构象是共轭体系Ⅱ的发光构象。

The application results from fluorination showed microwave heating could accelerate chemical reactions markedly. The reaction time could be shortened 50% at least than that of conventional heating. The relationship between fluorinating agents\' structure and their activity was studied systematically. In addition, an anhydrous KF with higher activity was prepared by using expansion effect of microwave heating. As we known, solvents were very important to reaction. The comprehensive study showed some less polar aromatic solvents could be used as dipolar solvents. In addition, they had better effect than dipolar solvents in some occasions, such as fluorination of chlorobenzaldehydes and chlorinated diphenyl ketones etc. The primary applications of ionic liquids were also studied which indicated reactions with ionic liquids as solvents were more efficient and simple.

研究表明，微波是一种节能高效的加热方式，在微波作用下的卤素交换氟化反应具有反应速度快、转化率高、选择性好的优点，其反应时间可较常规加热缩短50%以上；同时也系统地研究了氟化剂种类及制备方式对其反应活性的影响，并利用微波加热的膨化作用制备出了一种活性较高的KF，其活性与喷雾干燥KF相差不大；溶剂对反应具有重要的作用，在此系统地研究了强极性非质子溶剂和中等极性非质子溶剂的应用情况，发现一些中等极性的非质子溶剂如硝基芳烃和氯代芳烃类溶剂在氯代苯甲醛类化合物的氟化反应中具有比强极性非质子溶剂更好的使用效果。
