查询词典 retention

Effects of Polyvinylamines on drainage and retention of wood mechanical pulp and reed chemical pulp added with CaCO3 were investigated under neutrai papermaking condition.

本研究主要探讨了在弱碱性条件下聚乙烯胺对CaCO3加填的马尾松机械磨木浆和漂白芦苇化学浆的助滤、助留效果。

By field and indoor test, the paper measures soil physical property, soilmoisture constant and soil water movement parameter, provides the soil specificgravity , the soil apparent density, the soil fraction, the soil field moisturecapacity, the soil saturated moisture capacity, the soil percent moisture content ofcom germination and seedlings emergence, the corn wilting point, and alsoestablishes the equation of soil water retention curves, the equation of soil waterdispersion coefficient and the relationship between pressure and soil apparentdensity, and so those provides the parameter for numerical simulation.

通过田间和室内试验，测定了供试土壤的物理性质、土壤水分常数和土壤水分运动参数，得到了该土样的比重、容重、机械组成、田间持水率、饱和含水率、玉米种子发芽出苗土壤含水率、玉米凋萎系数，给出了土壤水分特征曲线方程、土壤水分扩散系数方程及土壤容重与土壤压紧力的关系，提供了数值模拟过程中所需的参数。

The results showed that tillage had stronger compaction effect on Red soil. By analyzing retention properties, water content was higher in the same suction for Red soil. Field capacity and wilting coefficient were higher for Red soil than those for Lou soil, but effective moisture and saturated hydraulic conductivity were lower for Red soil. For Red soil, Lateral infiltration ability was stronger, infiltration rate was greater than one number degree for Lou soil and preferential flow occurred easily.

结果表明：耕作片红壤有较强的压实作用；从持水特征分析，同一吸力下红壤的含水量较高，田间持水量和凋萎系数也高于塿土，而有效水含量略低于塿土，饱和导水率却低于塿土1个数量级；从入渗特征分析，红壤的侧渗能力很强，入渗率比塿土高1个数量级，容易发生大孔隙流。

And the retention rate is now so high, that the services are refusing some re-enlistment applications and reducing annual recruiting target.

超役留队率现在很高，所以各个军种都要拒绝一些再入伍申请，并降低年度招兵指标。

Ready-mixed concrete with high slump retention and high mechanical performance

高力学性能与高坍落度保持的预拌混凝土

The swelling capacity, water retention capacity and water combining capacity of oat bran dietary fibre under decoloring increased from 2 mL/g to 4 mL/g, 3.12% to 3.77% and 1.3% to 2.5%, respectively.

脱色后燕麦麸膳食纤维的膨胀力由2 mL/g增加到4 mL/g，持水力由3.12%增加到3.77%，结合水力由1.3%增加到2.5%。

Acquisition and retention of the target words was measured by the immediate vocabulary test and the delayed vocabulary test.

听完故事后就进行的即时测试和两周后的延迟测试分别考查了受试对6 个目标词的习得和保持情况。

The results showed that CPAM/BT greatly enhanced the retention and drainage; the smoothness and surface strength had obvious improvement; the two-sidedness difference was reduced; ink absorption ability and breaking length had some increment; paper had a better formation.

结果表明，CPAM/膨润土体系使浆料留着率和滤水性能大大提高，纸页平滑度和表面强度改善较为明显，减小了两面差，油墨吸收性能和裂断长有一定增加，成纸匀度较好。

Liddy had previously said in a letter to the treasury secretary, Tim Geithner, that lawyers had advised the company that "retention benefits" were enforceable in the courts and could not be withdrawn without causing a breach of contract.

而李迪在早前提交给财政部长盖特纳的信中则提到，律师们认为，如果诉诸法庭，该笔&预留奖金&将被判定必须强制发放，若不发放的话，将造成该公司违约。

It should be understood in relation to other aspects of modern football – an increased focus on ball retention in midfield makes movement in attacking positions more valuable, whilst the increased pace of modern footballers and the tendency to play on the counter-attack (primarily because there is more space to exploit) have also contributed.

现代足球中还有其他一些值得一提的因素使得无球跑动更加重要——控球权集中在中场区域使得前锋的跑位更有价值，同时，现代足球节奏和速度的提升以及防守反击的流行（防守反击使得更多的空间可供利用）。末尾少了一句话？&也起到了推波助澜的作用&

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
