Results The tinnitus frequency, severity of subjective tinnitus, audiogram types and some items of function test above hearing threshold were significantly different in the five groups (P.05). Specific features of pure-tone test were found in the five groups: tinnitus frequency was low, whole- frequency hearing threshold high, audiogram even, short increment sensitivity index at 1 kHz high and tone decline at 4 kHz low in the syndrome of invasion of wind-heat; tinnitus frequency was high, high-frequency hearing loss common, audiogram abruptly descending, SISI and TD at 4 kHz high in the syndrome of liver-fire up-stirring; subjective tinnitus was loud, audiogram abruptly descending or gradually descending, SISI and 7W at 4 kHz low in the syndrome of stagnation of phlegm-fire; tinnitus frequency was high, subjective tinnitus low, audiogram markedly descending or hill-like, SISI and TD at 4 kHz high in the syndrome of kidney-essence deficiency; average hearing loss was less, audiogram irregular but abruptly descending or notched in most cases, SISI at 4 kHz low in the syndrome of weakness of spleen-stomach.

Extreme climate elements such as torrential rain, extreme high temperature, extremely low temperature and so on are always used to analyze and evaluate an extreme climate event. There was a continuous sleeting and freezing process with low-temperature in the beginning of 2008. The process had the characteristics of large and sustained precipitation and snowfall, deep and long-time snow accumulation, long time in daily low-temperature with not so-low extreme low temperature. Therefore, it wasn't objective and accurate to choose any single one of these elements to analyze and evaluate this process.

评估极端气候事件，往往用某一项极端气候要素进行分析评估，如暴雨量、极端最高气温等。2008年初出现的持续低温雨雪冰冻过程，具有雨雪量大、持续雨雪时间长、积雪深、积雪时间长、低温持续时间长、但极端最低气温不低的特点，用其中任一因子评估定位该过程，都不能全面反映该过程的综合影响特征。

A typical case of polar low occurred on 26 February 1996 over the Sea of Japan is investigated. The analysis exhibits the spatial structures at different stage of this polar low event. At the initial stage of the polar low, the largescale environmental condition is characterized by a strong baroclinic zone in the low-level (below 700 hPa). The upper-level environmental circulation is almost barotropic. At the mature stage, a high IPV anomaly is situated over the surface polar low and a shallow layer of instability overtops the polar low center.

During the fracturing for low pressure and low permeability gas reservoirs, there are some main problems in conventional hydroxypropylguar - organic boron cross-linking system: Firstly, the water-lock damage to low pressure and low permeability gas formations by filter liquor; Secondly, the reason for alkali-sensitive damage in alkali-sensitive reservoirs is that conventional hydroxypropylguar - organic boron cross-linking fracturing fluids were cross-linked under alkaline environment, while the permeability of reservoirs is reduced greatly; Thirdly, the formation pressure is low, and the energy of flow back is not enough, at present, the main measure in oil fields is "injecting with liquid nitrogen", but this technique increased the cost of fracturing, making great troubles in operating, and leaving the liquid nitrogen also is a big problem.

在低压低渗透气藏的压裂改造过程中，常规羟丙基胍胶-有机硼交联压裂液体系存在的主要问题，一是压裂液滤液对低压低渗透气层造成的水锁损害；二是常规羟丙基胍胶-有机硼压裂液是在碱性条件下交联的，对碱敏性储层造成碱敏损害，降低储层渗流能力；三是地层压力低，压裂液返排能量不足，当前各油田采取的措施主要是&液氮伴注&技术，但是&液氮伴注&技术增加了压裂的费用，而且液氮存放也存在较大问题。

Based on the above cases, aiming at the actuality and practical cases of low-resistivity oil/gas reservoir log interpretation and evaluation in this thesis, beginning with analysing the intrinsic characteristics and physical properties of low-resistivity oil/gas reservoirs, all kinds of formation origin and mechanism of low-resistivity oil/gas reservoirs are analysed systematically and a great many of examples are given. Then the low-resistivity oil/gas reservoirs are classified by their formation origin. By setting up all kinds of interpretation models of low-resistivity oil/gas reservoirs, discussing and studying the low-resistivity oil/gas reservoir interpretaion and prediction methods, a set of practicable and systematic well logging interpretation and evaluation methods is obtained.
