Morphological and flourescent changes were assessed using confocal microscopy in whole-mount organ of Corti preparations. Results (1) After the animals were exposed to broadband noise at 122 dB SPL in 4 h/day for 2 days, both apoptosis and necrosis appeared in OHCs. The single strand DNA in apoptotic OHCs were observed both in guinea pigs and mice.(2) In normal OHCs, EndoG was distributed outside of nuclei. EndoG translocated from outside to inside of the nuclei in both apoptotic and necrotic OHCs following noise exposure.(3) The MNNG cochlear perfusion and noise exposure both caused the transloctation of AIF from the mitochondria to the nuclei. The translocation of AIF took place in both apoptotic and necrotic OHCs.

结果 (1)暴露于120 dB SPL的白噪声环境中每天4小时，连续2天后引起豚鼠和小鼠耳蜗外毛细胞凋亡时，其细胞核内产生ssDNA，而在正常细胞内没有三ssDNA；（2）在正常情况下，EndoG分布于耳蜗毛细胞的细胞核外，在暴露于上述噪声后发生凋亡和坏死的豚鼠耳蜗外毛细胞中，EndoG从细胞核外转移到细胞核内，细胞核中的EndoG显著增加；（3）豚鼠耳蜗外淋巴灌流烷化剂MNNG后发生耳蜗外毛细胞凋亡和坏死，在凋亡和坏死的耳蜗外毛细胞中，AIF自线粒体转移到细胞核，其变化与噪声损伤引起耳蜗外毛细胞凋亡和坏死时一致。

For all kinds of flowmeter, it is necessary to research on their characteristics from development to application.

摘 要：各种流量计从研制到使用，必须对其特性进行研究，对其标称的流量性能进行试验，并给出试验结果。

In this article two functional modes of the Fly-back Converter (Continuous Conduct Mode and Discontinuous Conduct Mode) are particularly analyzed, which include their characteristics, applications, the critical pattern of two functional modes is argued, both the exact boundary from the angle of circuit parameters is crystallized, at the same time, basic principle of PFC under the DCM mode is introduced, which settle theoretical basis for the subsequent design; by establishing the mathematic model of the converter, a further investigation of the configuration is made, qualitatively and quantitatively, analyzed to settle exactly theoretical basis for the subsequent emulation and the experimental parameter; from the angle of steady-state analysis, the transfer function of the system is deduced to establish dynamic small-signal state equation, emulating the system with the help of matlab, then according to the simulation result and the theory of PFC revise the system, lastly, we adopt the project which add a zero-pole compensator to the voltage loop, by this way, a satisfied system performance is gained and the PFC scheme is ensured successfully; finally, based on the previously-done work, we combining with the situation of specific design requirement, acquired the numerical value of each unit devices in this converter

详细分析了反激式变换器的两种工作状态，连续模式(Continuous Conduct Mode ，简称CCM)和断续模式(Discontinuous Conduct Mode，简称DCM)以及各自的特点、应用场合，论证了两种工作状态的临界模式，从电路参数的角度明确了二者的界限，同时还介绍了DCM模式下PFC的基本原理，为后面的设计奠定理论基础；通过对整个变换器系统建立准确的数学模型，对此变换器的电路结构做了进一步的研究，定性、定量地分析了变换器各部分的工作状态，为仿真和实验参数的确定以及电路参数的优化提供理论依据；从稳态分析的角度，为系统建立了动态小信号状态方程并推导出系统的传递函数，利用matlab对系统进行仿真，进而根据仿真结果以及PFC的相关理论对系统进行校正，采用在电压环加入零点—极点补偿器的设计方案，得到了满意的系统特性并且保证了PFC的顺利实现；最后，在前面所做工作的基础上，结合设计要求计算出此变换器系统中每个元器件的数值，利用Pspice对其进行了仿真、优化，然后根据仿真结果搭建了硬件电路。

Researching on it lies in affirming its reasonable value, on the other hand, for the sake of its value, we shouldn't get in that argue about the theory and its description, but standard legal technology so as to make the folk rules rise from "experience validity" to "standard validity", wisdom and contributions can be provided for the accommodation between state laws and folk rules.

对"私了"问题的研究志趣在于肯定其价值合理性的同时，使其理性层面的价值不纠缠于理论争论与描述中，而是通过规范法学的技术，使"私了"这类民间规则从"经验合法性"上升至"规范合法性"，为国家法与民间法的软性融通提供智识贡献。

Only if educators construct and create the actual education, the educatees can select something from it. The future education mainly depends on what educational choice the educators make presently. It means, the actual education is not the foreordination, but is decided by the educators'constructing and creating.

受教者作为参与教育的重要主体，他们对教育的需求，无疑对教育的实施起着重要的制约、影响的作用，但受教者对教育的制约和影响是从接受教育的向度，从既成的教育之中选择自己所需要的教育(包括学校、教师、课程等诸般教育资源)和向施教者提出自己所需要的教育，由于受教者不是教育的实施者，其对教育的制约和影响必须通过施教者得以体现，现有的教育和施教者的存在乃是受教者选择接受什么教育和如何接受教育的前提。

For 'Dancing Lady' from Oriflame, Gerresheimer has for example transformed transparent glass into an illusion of fragrantly swirling movement whose temperament is derived from ingeniously designed apparently multilayered spherical shapes combined with a delicately placed hint of white.

对于'舞蹈夫人从莲'，例如格雷斯海默已变成一个悍然旋转运动，其气质是从多层次的巧妙设计，显然与白色微妙暗示放在球面形状相结合产生的幻觉透明玻璃。

Bakhtin s translinguistics begins with his criticism on traditional linguistic-philosophical theories,especially on Freudianism and formalism.At the same time,Bakhtin is also influenced by New-Kantism and Marxism.At last,Muscovite ethos also effects in his linguistic ...

巴赫金的语言学思想首先是从批判传统语言哲学理论开始的，特别是对弗洛伊德主义和形式主义的批判，同时，巴赫金又以新康德主义和马克思主义等哲学思想为指导，此外，俄罗斯的民族精神也对其哲学思想产生了一些影响，形成了其独特的语言哲学基础。

In this paper, tolerance analysis mainly relates to three methods, viz."Extremum Method","Statistics Method" and "method of Monte Carlo". The character of the "Extremum Method" is to calculate the limit dimension of the close loop according to every limit dimension of the composing loop in order to ensure an entire frogging character, and get the tolerance of close loop.

极值法"的特点从保证完全互换着眼，由各组成环的极限值计算出封闭环的极限尺寸，从而求得封闭环公差；"统计法的特点是从保证大数互换着眼，根据各组成环的实际尺寸在其公差带内的分布情况，按某一置信概率求得封闭环尺寸实际分布范围，由此决定封闭环公差。

The paper narrated the Lu Ling's novel's polyphonic factors from three aspects: the relation of the author and protagouist; the novel structure and the figure's relation structure; the protagonist's inner monologues. It pointed out the novel's generation reasons and essential features by describing the static phenomena, at the same time, it embodied the ego generation of the essay's art features by Dostoevsky, Fyodor's novel creation.

文章从作者与主人公在作品中的关系、小说结构与人物关系结构、主人公的内心独白三个方面入手分析路翎小说中的复调性因素；在对此进行静态的现象描述的基础上进一步指出其复调小说产生的原因和本质特征，同时以陀思妥耶夫斯基的小说创作作为参照，凸现出其文本艺术特征的自我生成性。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.
