Everybody to the increment duty attention concentrates, in smuggles, deceives in the tax, but not the standard financial operation causes the increment duty to service improper processing wrong to give actually pays attention few, this article stands in enterprise's standpoint, the antipode easy to make a mistake the service and the accounting practice carry on the analysis, and summarizes a set of increment duty tax cut principle, comes to reduce the increment duty tax burden reasonably legitimately.

大家对增值税的关注都集中在偷税。骗税上，而对业务的不当处理和不规范的财务操作造成增值税错缴却关注较少，本文站在企业的立场上，对极易出错的业务及会计实务进行分析，并总摘要：大家对增值税的关注都集中在偷税。

The application area of products are not selective, so the industrial accumulation is provided with this factor in small and middle mineral enterprises.

矿业类产品的替代品非常少，并且在生产、销售领域极具有专业化的要求，产品的应用领域也不具备可选性，所以中小型矿业企业集聚化具备此项因素。

Therefore, the oil needs to be injected is very little, the needed load of oil and gas separator, filter core is also very light, the output of oil content of compressed air is also natural low.

故需要注入的油很少，需要的油气分离器，过滤芯负荷也很轻，输出的压缩空气含油量自然极低。

A novel Belousov-Zhabotinskii type oscillating reaction was observed in a closed serine-BrO^-~3-Mn^2^+- H2SO4 system(Ser-BZ system), which exhibited the followign characteristics:(1)Although Ser is unable to be brominated, the sustained oscillations could still be observed in the above system under batchreactor conditions even in the absence of either acetone or inert gas flow.(2)The present oscillations displayed extremely short induction period(0) and very few oscillation number(1).(3)Cl^-, acrylonitrile, or Br^- could effectively inhibit the oscillations. However, in the case when enough Ag^+ was addedinto the system to completely inhibit the oscillations in , the oscillations on the Pt-electrode could still be observed.

首次报道了间歇釜中以丝氨酸-BrO^-~3-Mn^2^+-H2SO4为体系的新型BZ类振荡反应，其特征如下：(1)虽然Ser不能发生溴代反应，但即使在无丙酮或惰性气体流时也能在间歇釜中观察到持续振荡；(2)振荡诱导期极短(～0)，振荡次数较少(1次)；(3)振荡反应受到Cl^-，Br^-，丙烯腈等的抑制；但当加入足够量Ag^+使的振荡抑制后，仍可在Pt电极上观察到振荡现象。

The present situation and development trend of the study on H2S/CO2 corrosion at home and abroad are analyzed, and the protection measures to the H2S/CO2 corrosion of oil-well tubular goods are presented.

目前对单含H2S或CO2(或含极少量H2S)时的腐蚀机理和规律研究较多，而对类似四川罗家寨气田同时高含H2S和CO2两种腐蚀性气体的腐蚀和防护方法的研究较少。1CO2腐蚀研究现状CO2腐蚀是由于CO2气体溶于水生成碳酸而引起电化学反应导致石油管材发生腐蚀。

The research, in animals, shows a significant correlation between the number of receptors in part of the brain for the neurotransmitter dopamine - measured before cocaine use begins - and the rate at which the animal will later self-administer the drug. The research was conducted in rhesus monkeys, which are considered an excellent model of human drug users.

动物（猕猴，猕猴是公认的用于研究人类毒品使用情况的极好模型，生物谷注）实验显示：可卡因使用前和开始沉溺于可卡因以后，大脑局部神经传递素多巴胺受体数量与药品剂量有显著相关性，可卡因的使用量越大多巴胺受体数量越少。

We also find that the contributions to intensity fluctuation from high frequency sidebands would be small because of the amplitude overlapping.

由于幅度的交叠部分过少，堆积脉冲的强度谱中极高阶频率处的起伏很小。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
