The ultrasonographic manifestation of PPCM was not specific, so the diagnosis of PPCM depended on peripartum history, left atrium and ventricle enlargements or cardiomegaly, decreased left ventricular function based on ruling out of other heart diseases.

PPCM超声表现缺乏特异性，超声诊断依据是有明确围产史，出现左心系统或全心脏扩大，心功能减退，其表现不能用其它心脏病解释者。

Cardiopathy is one of the most prevalent diseases in endangering people's health.And ECG is an important diagnostic tool for assessing heart function.

心脏病是威胁人类健康的主要疾病之一，而心电图是其诊断的重要依据。

In this paper two wholly aromatic copolyesters, LCP-111 and LCP-116, provided by Chenguang Institue of Chemical Technology, were blended with two types of high performence engineering plastic, poly and poly with cardo group respectively. Research work was done on the phase morphology, phase separation process, crystallization and melting behaviors and their influence on the properties of LCP/PEEK and LCP/PES-C blends.

本文使用国产的仿Xydar全芳共聚酯LCP分别与二种新型的高性能工程塑料聚醚醚酮和酚酞型聚芳醚砜共混，主要对LCP及其与PEEK，PES-C共混物的相态结构，相分离过程，结晶和熔融行为以及这些因素对性能的影响做了大量的基础研究工作，这些工作是实用改性的理论依据，并且是高聚物共混理论研究中的一个新领域。

Of the property of haven, carriage circuitry convenient the international trade center that the international of be in harmony of main basis; that the fixed position with the government sector is affirmatory bridgehead carries center, banking center, message center to be an organic whole, the; of main function fixed position that is bridge tower is based on even cloud harbor this just about and be by establish bridge of new Asia-Europe mainland east bridge tower.

港口的性质、运输线路的便捷和政府部门的定位是确定桥头堡的主要依据；融国际运输中心、金融中心、信息中心为一体的国际商贸中心，是桥头堡的主要功能定位；连云港正是基于此而被确立为新亚欧大陆桥东桥头堡。

However, one cannot carry this to the extreme by regarding culture transference as the nature of translating.

但是，把文化转换看作翻译活动的本质却使问题走向了极端，是缺乏理论和实践依据的。

At last,countermeasures are proposed to improve the water resources carrying capacity.

同时，提出了提高水资源承载力的对策，为今后的区域水资源开发利用提供依据。

The carrying capacity is the main foundation of rational allocation of water resources .

水资源承载能力是水资源合理配置的基本依据。

Cash flow plan is another important activity in cash flow management. It expresses the cash flow forecast and decision in value way so that they could be understood by the persons who will carry it out. It plays a carrying-on role in cash flow management.

现金流量计划是企业现金流量管理的又一重要内容，它要将现金流量预测和决策结果以价值方式，用具体的和现金流量管理人员可以理解的方式详细地表现出来，作为后续管理活动的重要依据，因而它在现金流量管理活动中处于承上启下的地位。

Based on the involute's basic principles and theoretical formulas, input the involute's formulas of cartesian coordinates into the equation editor, accordingly create the precise involute of gear's contour. Based on the formula of helical gear's parameters, accurately create a curve of tooth profile. Create the chraceristics of helical gear by ordering of swept blend and array.

依据渐开线生成的基本原理和理论公式，在方程编辑器中输入渐开线的笛卡尔坐标方程，从而生成精确的齿轮轮廓渐开线；根据角变位斜齿轮各参数的计算公式，精确创建了齿廓曲线；利用扫描混合和阵列命令创建斜齿轮的轮齿特征。

This article is a case study according to the method of public policy enforcement.

本文以公共政策的执行理论作为案例研究的依据。

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

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
