The results revealed that treatment with mannitol retarded cell senescence,enhanced the ability of cells to redifferentiation,and reduced the activities of both peroxidase and IAA oxidase.Although treatment with 6 BA reduced the activity of peroxidase obviously,the influence of 6 BA in IAA oxidase and cell senescence was not significant.

结果表明，甘露醇处理能延迟水稻细胞衰老，提高细胞再分化能力，降低细胞过氧化物酶和 IAA氧化酶活性；6- BA( 2 mg/L )虽然明显降低细胞过氧化物酶活性，但对 IAA氧化酶及细胞衰老无明显影响。

The research work done is presented as follows:Compound dewatering technique of vacuum tube well is an effective technology for solving the dewatering problems of aquitard and interface relict water according to physical simulation test and field test. The variation laws, such as degree of vacuum, pore water pressure in different strata, have been studied. The results show that there is a certain scope of influence of vacuum in strata, and the vacuum degree in the horizontal direction decreases gradually with the increase of the distance from the main well; the change law of degree of vacuum in the vertical direction increases firstly and then decreases with the depth of soil strata, and changes with different soil nature and depth; changes of pore water pressure in soil strata has also shown a similar law of degree of vacuum.

主要研究工作如下：通过室内物理模拟试验和现场试验均证明了真空管井复合降水技术用于解决弱透水层和界面残留水疏干难题的有效性；并且对不同地层中真空度、孔隙水压力等变化规律进行了研究，发现地层中真空度均有一定的影响范围，且真空度在水平方向上随距主井距离的增加而逐渐降低；在垂直方向上真空度随深度总的规律是先增加后降低，并随土层性质及深度的不同而变化；土层内孔隙水压力也呈现出与真空度类似的变化规律。

Through a complete cycle of raising interest rates after this week lowered interest rates for the first time, but for the time being due to the abolition of tax on bank deposits, the bank's depositors did not reduce the number of receipts, before the rate cut The one-year deposit rate of return on investment for 3.933 percent, to cut interest rates after an investment return of 3.87 percent, and 10,000 yuan a year-to-deposit interest rate reduction of only 6.30 yuan, so that the bank will cut interest rates failed to exercise any time In the stock market to the role, it may not bring immediate relief to stimulate consumption, the rentier will still be money in the bank to ease food profits.

降低首次利率，但暂时由于税银行存款，银行的存款并没有减少多少收益取消前降息的一年为3.933的百分之投资回报期存款利率，削减后的投资回报百分之3.87的利率，并万元一年来，存款利息只有6.30元，率降低，使央行将降息未能行使任何在股票市场的作用的时候，却未必会即时援助，以刺激消费，食利者仍将在银行存款，以解决粮食利润。

Numerical Simulation and Experimental Investigation on A Thermoacoustic Engine with Tapered Resonance Tube A symmetrical standing-wave thermoacoustic engine with tapered resonance tube has been numerically simulated with liner thermoacoustics. The simulation shows that using tapered resonance tube in thermoacoustic engine could decrease the velocity amplitude and lower the total acoustic power loss in the resonance tube. The experimental results indicate that the harmonic was suppressed effectively by using the tapered resonance tube, and the pressure ratio was improved.

采用锥形谐振管的热声发动机的数值模拟和实验研究利用线性热声理论，对一台采用锥形谐振管的驻波型热声发动机进行了数值模拟，发现采用锥形谐振管可有效降低工质气体的速度振幅，进而减小在谐振管中声功率的损失；与一台在相同频率下工作的采用等直径圆柱谐振管的驻波型热声发动机进行了实验对比，结果表明，在使用锥形管作为谐振管的热声发动机系统中，谐振管中的非线性效应得到了明显的抑制，热声发动机在基频模式下稳定运行，压比增大而加热温度降低。
