The personal income tax exemption volume law system as its tax revenue reduces the system, day by day also has become an important system relating to national economy and the people"s livelihood, but this system continuously has rarely had the change since 1994, but inhabitant"s income level unceasingly enhances, the price also unceasingly rises, in recent years our country promotes the housing system, the medical system, the social security system, the educational system and so on many reform measure, obviously, at present our country personal income tax exemption volume legal system and the development of economy and society are in disconformity, the function of adjusting income assignment gradually weakens, the unfair tax burden question extrudes day after day, The perfection of our country personal income tax exemption volume law system call is more and more high, the experts and the scholars also pays more and more attention to the research of this system.

个人所得税免征额法律制度作为一项税收减免制度，也日益成为了税法当中一项关乎国计民生的重要制度，但该制度自1994年以来一直鲜有变化，而居民的收入水平不断提高，物价也不断上涨，近几年来我国又推出住房制度、医疗制度、社会保障制度、教育制度等多项改革措施，显然，目前我国个人所得税免征额法律制度与经济社会的发展情况已不相适应，调节收入分配的职能逐渐削弱，税负不公的问题日渐突出，完善我国个人所得税免征额法律制度的呼声越来越高，专家和学者也越来越关注该制度的研究。

The change from granite to foliated granite is transitional and there is no discontinuity between them.

从花岗岩到片理化花岗岩的变化是逐渐过渡的，二者之间不存在不连续面。

This change was made because of the feeling that perhaps Python's divi- sion operator has been flawed from the beginning, especially because Python is a strong choice as a first programming language for people who aren't used to floor division.

之所以会有这种变化是因为 Python的核心开发团队认为Python的除法运算从一开始就设计失误。特别是，随着Python的逐渐发展，它已经成为那些从未接触过地板除的人们的首选学习语言。

Oriental fruit fly Bactrocera dorsalis is one of the dangerous quarantine pests of the world. Its hosts range is very so wide that it can harm more than 250 species fruits and vegetables. With the change of climate, adjustment of plant structure and increase of international trade, the area that has been harmed by oriental fruit fly is increasing.

桔小实蝇Bactrocera dorsalis 是一种世界危险性检疫害虫，寄主范围广，能危害250多种瓜果蔬菜，随着气候变化、种植结构的调整和国际贸易的增加，其危害面积逐渐扩大，给果蔬业带来严重的经济损失。

With our standard of living has been increasing in the surrounding environment has undergone a drastic change.

随着我们的生活水平逐渐提高，四周的环境也发生了很大的变化。

Apparently, the evolution have generated the situation of the separation of monosyllabic form and disyllabic form, and thus generated the form system of direction words. The totally different paralleling dual system is the basis of the later evolution. The monosyllabic and disyllabic direction words has gradually come into the weakened meaning or morpheme,while disyllabic direction words has more substantive nature,with more freedom in the sentences.

可见，语义的发展变化最终导致了汉语方位词形式系统单双音节两分的局面，这两种形式方位词的不同语义特点也是后来发展演变的基础，单音节方位词逐渐走向虚词性或词法平面，而双音节方位词则具有更多的实词性，更为自由地出现在句子中。

With the help of dynamic mechanical thermal analysis, differential thermal analysis, analysis of curing behaviors and swelling test, the change of structure during the vulcanization of ebonite was analyzed. It is found that the chemical cross-linking in the ebonite trended to descend with degree of vulcanization, while the modification effects of polar groupings on the carbon backbone gradually increased, which dominated its physical and mechanical properties.

通过考察硫化时间对于硬质橡胶结构与性能的影响，结合DMTA、DSC、硫化特性分析、溶胀分析等方法，分析了硬质橡胶的硫化过程中结构的变化，认为在硫化过程中，随着硫化的进行，硬质橡胶中的化学交联作用有下降趋势，极性基团对于碳骨架的改性作用逐渐增加，并对硬质橡胶的物理机械性能起主要决定作用。

The results were showed as following: The growth of fruit size appeared to be a markeddouble- peak curve and was affected by the rainfall, Thedifferences in endosarc were decided by changes of citric acid and soluble sugar content which showed opposite variety.

结果表明：果实纵横径生长动态均呈双高峰曲线，且与降雨量密切相关，内质的差异主要体现在柠檬酸和可溶性糖的变化上，菲诺的柠檬酸含量一直上升，而尤力克的柠檬酸含量在采前有下降趋势。菲诺的可溶性糖积累逐渐增多，而尤力克不断下降。

In addition, soil acidity presented significant and positive correlations with percentage of DTPA extractable Cd and Pb in their total contents.

在84d以内，随着时间的延长，金属的DTPA浸提量逐渐下降，84d到168d内，金属的DTPA浸提量变化不大。

The increased number of mitochondria in tetraploids seemed to adapt the demanding of more energy for fecundation in tetraploids because of larger size. 3 Biochemical compositions in gonad and adductor muscle between diploids and triploids in the Pacific oyster, Crassostrea gigas, during an annual period were examined.

三、对二倍体与三倍体太平洋牡蛎的性腺和闭壳肌生化组分含量2003.4-2004.3的年度变化的分析结果显示：二倍体牡蛎性腺糖原含量在配子发生过程中明显降低，至性腺成熟时降低了78.57%（P＜O.01），繁殖期维持在较低水平上，繁殖期过后逐渐升高，10月份至翌年3月份都保持较高的水平。

The split between the two groups can hardly be papered over.
