By inadvertently sending the dog a "let's play" message via excited and overenthusiastic petting and voice, we end up sending a mixed message, and this blurs the line between play and work.

由激动和过于热情的抚爱和声音而漫不经心传达给狗一起玩耍的信息，我们必须终止传达这种混淆的信息，因为这会模糊玩耍和工作之间的界线。

Based on the paleoceanography spatial database, I replanned the paleoceanography databasesystem to figure out the security of the former system. I redivided the system functions anddesigned five function modules: right management module, data import and edit module,calculating year module by standard oxygen isotope curve, data analysis module and spatialanalysis module. The calculating year module adopted the method which compares the oxygenisotope stage borderlines. This method could acquire a more exact result and provide a friendlyinterface to make the consumer operate convenient.

在古海洋空间数据库的基础上重新规划设计了古海洋学数据库系统，解决了原系统数据库的安全性，将系统功能重新进行划分，设计开发了权限管理、数据输入编辑浏览、标准氧同位素定年、数据分析和空间分析等五个系统功能模块，其中标准氧同位素定年模块采用了对比氧同位素期界线的方法，使年代计算结果更加精确，并提供了友好的界面方便用户的操作。

Each unitis of different biotic characters and displays different features of seawater composition during the time. 2 The black unit including a biotic extinction was caused by oceanic anoxic event. Crisis that deepwater keeled foraminifera encountered represents a ferocious anoxia in deep marine environment . Biotic recovery in gray unit reflects gradually improved marine circumstance. What the biotic extinction at the C/T boundary in black unit reflects an environmental mutation, whereas the gradual biotic change characterize the recovery of marine dissolved oxygen environment in a stepwise process. The red unit is the result of oxic deposition and characterized by extremely abundance of foraminiferal faunas, which reflects a high-oxidized marine circumstance. 3 As the most ordinary biotic index in paleoceanography researches, foraminifera represent anexcellent environmental indicator in this paper.

三套岩层表现出不同的生物特征，并指示出当时海水的不同性质。2黑层段是大洋缺氧造成的结果，生物大量灭绝，深层水具旋脊有孔虫的所遭受的危机反映出当时海洋深层水体严重缺氧的特征；灰层段中生物的恢复反映出海洋环境自缺氧事件之后的逐步改善过程，与黑层段反映的C/T 界线处生物绝灭反映的环境突变不同，灰层段生物特征的渐变指示出当时海洋溶解氧环境的恢复也是一个逐步的过程；红层段属于富氧沉积的产物，特征是有孔虫生物的极度繁盛，反映的是一种高氧化性的海洋环境。3有孔虫作为古海洋研究中最常用的生物指标，在本文研究中显示了良好的环境指示性。

Angle handle long, the top two bifurcation, or was palmate, no corner section and there is no separation between the two boundaries.

单独构成一科。角柄长，上端二分岔或呈掌状，无角节和二者间亦无分开的界线。

Besides, the Mobius strip can represent the blurring boundary between "reality" and "fiction" in postmodern fiction. The Mobius Strip also symbolizes some other significant characteristics of postmodern parody, such as the dual level of parody, the double-voiced aspect of parody, and the intimacy between the parodied text and the parodistic text.

它是后现代小说中常见的「无限倒退」的表徵；此外它也可代表后现代小说中现实与虚构间模糊的界线；它同时也象徵后现代戏拟中许多重要的特徵，譬如戏拟中的双重层次、双重声音及被戏拟文本与戏拟文本的密切相关。

The phylogeny of the genus Machilus was analysed by means of Bayesian Inference of nrDNA ITS sequences . Our results indicated that Machilus is a monophyletic clade within the Persea group, and its persistent and spreading to reflexed tepals on fruit are an important character for its generic delimitation against the related genera Phoebe, Alseodaphne and Persea .

应用nrDNA Internal Transcribed Spacer 序列，使用Bayesian 分析法对樟科润楠属的系统学问题进行了初步探讨，结果表明润楠属在鳄梨属群中本身作为一独立分支，是一个自然的单系类群；由于其花被裂片果期宿存且强烈反转与同产自亚洲的楠属和油丹属存在清晰界线。

But there were many pseduo-prophets in the nation, and so some authority was necessary to draw the line between the true and the false prophetical writings.

但有许多pseduo -先知在全国前列，所以有一定的权力是必要的，以划清界线之间的真与假prophetical著作。

CT is important means for diag-nosing the diseases originated from bladder,prostate and seminal vesicle but it does not entirelysatisfy early diagnosing prostatomegaly or tumor.

CT虽然作为膀胱、前列腺和精囊等疾病诊断的重要手段，但是对前列腺肥大或肿瘤早期诊断有一定限制，特别是当前列腺与精囊及膀胱底融合为软组织块状影，界线不清时，与肿瘤外侵不易鉴别。

From medial to lateral, the cerebral cortex can be divided into three parts: hippocampus, general cortex and pyriform lobe, there is no distinct boundary between them, but the cell organization is different.

从内侧到外侧，大脑皮层可分为海马、新皮质和梨状皮质三部分，三者之间无明显界线，细胞排布有所区别。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
