The most amazing characteristic of the komodo dragon is that the female can lay eggs that hatch without being fertilized by a male.

而他们最令人叹为观止的特点是：科摩多巨蜥可以单性繁殖——即雌性科摩多巨蜥可以再未受精的情况下产蛋。

Theory of kinetic energy factor adjusts production to be in charge of column internal diameter, it is the application below the case that there still is certain energy in air pocket yield water.

动能因子理论调整生产管柱内径，是在产水气井尚有一定能量的情况下应用。

In this paper, using sodium acetate, sodium propionate and sodium butyrate as the unique carbon source, 5 58%、3 90% and 4 98% PHAs of dry sludge weight were obtained by assimilated sludge as PHAs synthesis strai...

实验表明，污泥微生物里广泛存在PHAs合成菌，厌氧条件比好氧条件的PHAs产率要高；最佳的实验条件下得到PHAs的量占污泥干重的 1 2 3 2 %，此时碳源转化率为 3 0 65 %。

The behavior of the tested silica glass, in which multiphoton absorption existed but no darkening occurred, was also described.

此外，对石英玻璃在飞秒激光作用下虽存在多光子吸收但并未产生光致暗化的原因作出了解释。

The longest lifetime component in PALS results is ascribed to the annihilation of positronium in cavities of PS sample. It is found that 80% of the positrons implanted in PS film have formed positronium atoms. PALS results show that the lifetime of ortho-Positronium has small value when the sample was in oxygen gas medium compared with those in other medium.

正电子湮没寿命谱测试结果表明，样品中存在长达40ns的电子偶素湮没成分，并且进入多孔硅膜层的正电子约有80%形成电子偶素，具有非常高的电子偶素产额；在氧气气氛下，由于气体导致o-Ps发生自旋转化猝灭是使多孔硅样品中电子偶素寿命缩短的主要原因。

The snowmelt and glacier meltwater will increase, and the evaportranspiration will also increase.

全球变化情景下的预测结果表明，未来黑河干流山区产流量会增加，冰雪融水和蒸散发也会增加。

At 80℃, the yield of esterification of benzoic acid with ethanol could reach 95% by using 10% catalyst for 6 h; the conversion of toluene in the nitration with 1 equiv. of 65% nitric acid could be achieved to 99% by using 5% catalyst for 5 h.

在80℃下，摩尔分数为10%的Yb(NTf2)3负载催化剂，反应6h可使苯甲酸乙酯的产率达95%；摩尔分数为5%的Yb(NTf2)3负载催化剂，反应5h可使甲苯与等摩尔质量分数为65%硝酸的硝化反应转化率达99%。

Thanks largely to financial support from the national labor unions, which my friend and regional AFL-CIO leader Dan Powell pushed hard for, we got enough money to do some television ads.

在很大程度上要感谢全国工会的经济资助，我们才得到足够的钱用于电视宣传广告。劳联-产联的地区领袖丹。鲍威尔是我的朋友，资助是在他的极力推动下促成的。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
