The surface of its seeds is covered by a layer of gum, Artemisia seed polysaccharide. ASP has been found to possess high viscosity which is 1800 times as much as that of gelatin and strong hydroscopicity, for which it can absorb 60 times its self weight of water, and there are aslo a great of oil in its seeds, Artemisia oil.

其种子表面富含一层胶质——ASP，ASP有很多优良的特性，如吸水性——可吸取自身重量60倍的水，高粘度——是明胶的1800倍；同时，沙蒿种子中又含有大量的油脂——沙蒿油，其又有着丰富的亚油酸。

The WAR of HWAR with lower WAR such as polyacrylic salt graft polymer decreased more slowly at the same fertilizer concentration than that with higher WAR except urea and monoammonium phosphate. But the polyacrylic salt graft polymer with higher WAR could resistant higher fertilizer concentration.

但不同肥料品种对HWAR吸水倍率的影响程度不同：供试肥料中，尿素由于是中性分子，它对HWAR吸水倍率的影响最小，其它肥料对HWAR的影响程度依过磷酸钙、磷酸一铵、硫酸钾、氯化铵、硫酸铵、氯化钾顺序递减。

The reason is that the population of the ground state descends and the population of the first-excited state increases in the two-color coherent lase relative that in the monochromic laser and the transition channel of the electron to the even-parity continuum

氦离子在添加倍频光的双色场作用下高次谐波产生效率极大提高的原因是：倍频光极大地加快了电子电离到连续态及返回基态这一过程，使辐射出的高次谐波光子数大大增加，该初步阐释可为高次谐波真正应用到实际中提供一些理论启示。

In order to obtain viable tetraploids, which remains a major challenge worldwide, research on spindle organization and chromosome behavior was carried out mainly in zhikong scallop, Chlamys farreri, a typical commercially important species which is being cultured in North China Sea. Immunofluorescent technique and laser scanning confocal microscopy has been developed for observation of both microtubule organization and chromosome segregation. Orcein squash method was also used for chromosome observation. A series of complicated configurations of the meiotic spindle and associated patterns of chromosome segregation, including tripolar and seperated bipolar segregation, were found in developing eggs following the inhibition of the first polar body.

为了攻克可存活四倍体人工培育技术的国际性研究难题，本研究选取了我国北方海区的典型经济贝类栉孔扇贝为主要研究对象，建立了一套免疫荧光染色和激光扫描共聚焦显微技术，结合使用染色体地衣红压片观察技术，对第一极体受抑制的受精卵的减数分裂纺锤体装配、染色体分离动态进行了研究，发现了一系列特殊的纺锤体装配及相应的染色体分离行为，包括三极分离、独立二极分离等分离类型，从亚细胞水平上阐明了四倍体形成的细胞学机理。

Four keyboards were judged potential health hazards and the microbiologist recommended the removal of one keyboard as it had 150 times the pass limit of bacteria -- five times filthier than the swabbed toilet seat.

发现有四个键盘存在潜在的健康危害。这位微生物学家建议将其中一键盘清除因为它上面的细菌数超标150倍。这比清洗后的马桶座都要脏5倍。

At fifth grade, the automatic readers were reading twice at fast as the others, and still outscoring them on accuracy, comprehension and vocabulary.

罗斯曼发现，一年级中的自觉阅读的学生阅读的速度是其他孩子的三倍，在阅读理解测试上的得分是其他孩子的两倍。

We have this experience in our daily life: when planning to rive off a cloth, we have to firstly cut a small rift on the place which to be tore; with this small rift, the cloth can be rived off easily; if without this small rift, the cloth is hard to be rived off even when you use multiple or dozens of multiple forces.

生活中我们都有这样的经验，当我们要将布撕开时，先要在欲撕开处剪一个小切口，有了这个小切口，稍用力一撕，不久撕开了；若没有这个小切口，用几倍、几十倍的力也难以撕开。

An infant's birth weight usually doubles in four to six months, and triples at one year.
