程度

The most serious desertification occurred in southeast of MuSu Desert,then appeared inferior degree in midst,north,south and east,anddegression degree in other directions.6.The changes of environment in Mu Su Desert in historical times havebeen controlled by climatic changes in temperature and drought-wetwithin hundreds or thousands years.At present,it came into being suchspatial structure and environmental characteristics fordesertification land because of being relative to other naturalgeographic characters and human activities.In all that,physiognomyand hiemal wind are the driving factors.The sandy matter in stratumis the physical fountain factor.The depravation of surface water inthis region is one of representations of environmental changes, meanwhile,it is also the factor which leads to the degradation ofvegetation and desertification.On the whole,human activity has actedupon these natural elements,becoming a dominant factor in the regionalenvironment changes since Ming and Qing dynasty.7.Influencing of human activities on the environment of Mu Su Deserthad occurred before Qin dynasty,and its intensity of earlier influencewas so slight that it could not cause a large scope and long timeenvironmental changes.

沙漠化的程度是东南部最强，中北部、南部和东部次之，而后向其他方向递减。6、毛乌素沙地历史时期的环境变化是受百年乃至千年尺度的气候冷暖、干湿变化控制的，之所以形成目前这样的沙漠化土地空间分布格局和环境特征，则与其地的自然地理特征和人类活动有密切关系，其中地貌及冬季风是动力因素；地层中的沙物质是物源因素；地表水环境恶化是区域环境变化的表现之一，同时又是植被退化和沙漠化的引致因素；人类活动总体上是叠加在自然因素之上的，只是明清以来在局地环境变化中成为主导因素。7、毛乌素沙地人类活动的环境影响在先秦时期就已出现，早期的影响程度是轻微的，不足以造成大范围、长时段的环境变化。

结果：随着缺血时间的延长，肠壁的缺血损害程度逐渐加剧。D-乳酸的活性在术后2小时就随着缺血时间的延长，肠壁组织缺血程度的增加而逐渐升高，与手术前相比，P.05。

Blinded biopsies were evaluated by a histopathologist and scored according to Knodells histology activity index. Results 53.5%(54/101), 51.5%(52/101) and 31.7%(32/101) patients had a reduction of their total hepatic HAI score, necroinflammation and fibrosis scores by ≥2 points or 1 points at the end of one year of lamivudine therapy, compared with their pretreatment values, respectively.

结果 治疗后53.5%（54/101）患者肝组织学改善（治疗后HAI积分下降≥2），HAI积分由治疗前的8.0±4.7下降至治疗后5.2±3.3（t＝7.358，P.01）；其中51.5%（52/101）患者坏死炎症程度改善(治疗后积分下降≥2)，坏死炎症积分由5.9±3.8下降至3.6±2.5；31.7%（32/101）患者纤维化程度改善（治疗后积分下降≥1），纤维化积分由2.1±1.2下降至1.6±1.2（t＝3.827，P.01。

Network advertisement than other media the largest dominant position is interactive sex, easily enterprise and consumer establish one-to-one sale relationship, the association between person of no less than and person carries each other communication and channel an versatile person only can promotional each other concern is same, interactive means makes advertisement is mixed by the conduct propaganda that sets out from company point of view so homiletic the communication that turns into to set out from consumer angle and communication, increased a target to suffer greatly numerous pair of advertising welcome degree and accept rate.

网络广告较之其它媒体最大的优势便是互动性，易于企业与消费者建立一对一的营销关系，正如人与人之间的交往只有通过相互的交流与沟通才能增进彼此的关系一样，互动方式使广告由原来从企业角度出发的宣传和说教变为从消费者角度出发的沟通与交流，大大增加了目标受众对广告的欢迎程度和接受程度。

The results of logistic regression revealed that younger groups, administrators and laborers, lower personal yearly income, self-perceived unhealthy, the level of hypersomnia, and abnormal weight were more likely to have accident injuries. Considering to the extent of association, the most important factors are self-perceived health, the level of hypersomnia, and age group.

研究结果发现，台湾民众发生事故伤害的逻辑斯回归模型显示年龄愈低、行政人员与劳工、个人全年收入愈低、自觉健康状况愈不健康、嗜睡程度愈严重及体重愈超越正常范围者愈可能发生事故伤害，其中对於事故伤害发生之影响力最大者为自觉健康状况，其次是嗜睡程度，再者为年龄。

In order to keep consistent with GB 50235-97 "Construction and Acceptance Specification for Industrial Metal Piping Works" and SH 3059-2001 "General Regulation on Material Selection for Petrochemical Piping Design", this revision has only defined the extreme harmful medium as virulent medium, and, piping with the transmission hypertoxic levels of moderate harmful and gentle harmful medium is added in the application scope.

本次修订为保持与 GB 50235-97《工业金属管道工程施工及验收规范》和 SH3059-2001《石油化工管道设计器材选用通则》协调，仅将毒性程度为极度危害介质定义为剧毒介质，同时在适用范围中增加了输送毒性程度为中度危害和轻度危害介质的管道，并增补了有关施工及验收规定。

Moreover, based on the petrochemical industrial characteristics, this specification has defined benzene piping with a hypertoxicity level of extremely harmful medium as Grade SHB piping and acrylon, carbonyl chloride, carbon disulfide sulphide and hydrogen fluoride piping with a hypertoxicity level of high harmful medium as Grade SHA piping.

Based on Hutchinson niche and Guangxia Cao\'s definition, Fuzzy hypervolume niche evolves the theory of fuzzy niche: the niche is a fuzzy hypervolume; the niche of the species is a hypervolume with fuzzy boundary which is formed by the n-dimensional resources (time, space, temperature, humid, trophic,...) necessary for the species\' continuous existing and multiplying; membership of a point in the niche is equivalent to the adaptive degree of the species to the point of the environmental resources.

在Hutchinson生态位和Guangxia Cao的定义的基础上，模糊超体积生态位发展了模糊生态位理论：物种的生态位是可以使物种生存和不断繁殖的n维环境变量(时间、空间、温度、湿度、营养……)所形成的边界模糊的一个n维超体积；隶属函数表明n维资源空间的一个点x属于生态位的程度，也表明物种对环境资源的适应程度。

At the one-cell stage, each embryo was injected with gradient doses of 2-8ng MO. The control morpholino, was purchased from Gene-Tools.To test the knockdown effectiveness of the morpholino, the tbx2-EGFP (enhanced green fluorescent protein) construct was generated. And coinjection of morpholino with mRNA tests its specificity of the morpholino. Overexpression of tbx2 via mRNA microinjection helps us understand gaining function of tbx2. Results The tbx2-EGFP construct tests the knockdown effectiveness of the morpholino. Zebrafish embryos lacking tbx2 function have defects in cardiac contractility, rhythm and morphology in a dose-dependent manner. The embryos with c-MO are normal in development. Coinjection of morpholino with mRNA rescue the phenotype of tbx2 knocking down. The phenotypes include pericardial edema, hypogenetic ventricle, dilation of atria, arrhythmia, bradycardia, asystole, abnormal atrioventricular canal, aberrant valve and blood regurgitation.
