And due to the nature of the data acquisition, three data acquisition circuit board are adopted. They are voltage to digit data converting circuit board, current to digit data converting circuit board and digit data input/output circuit board. These circuit boards are used to acquire the main running parameter of the multifunctional experimentation equipment and to control the output of alarm message.The monitor and control program is developed on Delphi5.0 which is an excellent product of Borland Corp.

The paper presented a method of detecting long-range correlation in a signal--detrended fluctuation analysis and applied it to diagnose gear faults. Two key problems, i.e. scaling range and polynomial order of fitted trend, were discussed. Scaling exponent was extracted to be as a detector for diagnosing five types of gear faults, their were normal, spalling, tooth broken, wearing and cracking.

The results showed that there was a negative relationship between H2O2 content and CAT activity, thus H2O2 content was low when CAT activity was high. There was a close relationship between H2O2 content and differentiation process. H2O2 could be an important signal transduction factor during bud differentiation. IAA oxidase activity was decreased firstly, and then increased, which affected IAA oxidase and degradation pathway and regulate ratio of cytokinin and auxin. With differentiation process continuing, PPO activity was increased, which could cause browning or vitrifaction of seedling, or even malformation.

研究结果表明，鹅掌楸组培再生过程中，过氧化氢酶活性与H2O2含量变化呈负相关，CAT活性较高时，H2O2含量则较低。H2O2含量与鹅掌楸组培苗分化进程密切相关，H2O2可能作为信号因子在芽分化过程中发挥重要作用；IAA氧化酶活性呈现先下降后增加的变化规律，从而影响IAA氧化降解途径，调控细胞分裂素与生长素含量的比值，影响鹅掌楸芽的再生；PPO活性随培养时间的增加而升高，引起组培苗的褐变或玻璃化，甚至生长畸形。

One, serve as a signal generator with computer, the software of COOLEDIT of sine sound wave that produces a standard is software of the acoustic frequency processing with a kind of powerful function and editor, it can be generated, broadcast the voice that with transcribe we need, the weaveform that can show phonate news undertakes study for us, be acoustics research and acoustic frequency processing

Background— Protein kinase A signaling has long been known to play an important role in cardiac function. Dysregulation of the protein kinase A system, caused by mutation of the protein kinase A regulatory subunit gene PRKAR1A, causes the inherited tumor syndrome Carney complex, which includes cardiac myxomas as one of its cardinal features. Mouse models of this genetic defect have been unsatisfactory because homozygote null animals die early in development and heterozygotes do not exhibit a cardiac phenotype.

背景——蛋白激酶A信号传导在心功能中发挥了重要作用早已为人们所知蛋白激酶A调节亚基因PRKAR1A的变化引起蛋白激酶A系统失调，导致了遗传性卡尼复合肿瘤综合症，其中包括的心脏粘液瘤作为它的一个主要特征此种遗传缺陷的小鼠模式仍然不能令人满意，因其纯合体空白动物在发展中早期死亡，而杂合体不能显示心脏表型

The valve motion, the work process of the cylinder and the change of the pressure in the valve chamber are related by "pressure inspire", and the corresponding mathematical model is set up.

考虑某些实际应用中直接测取往复压缩机气缸压力的不便，提出采用阀腔脉动压力替代气缸压力，未作为热力参数法的主要故障诊断信号的新思路，并通过&压力激发&将阀片运动规律、气缸工作过程和陶腔压力变化互相联系起来，建立相应的数学模型。

To Israel and its Arab neighbors it surely signaled that whoever moves into the White House next January, there will be no swerve from Bush's role as guarantor of Israeli intransigeance.
