Schizocarp A dry fruit, formed from two or more carpels, that divides at maturity into one-seeded achenelike segments termed mericarps.

分果：干果的一种类型，由二个至多个心皮合生形成。在果实成熟期可以分裂为含有单个种子的类似瘦果的部分，称其为双悬果。

The late Jurassic Stegosaurus, like the pair walking through a North American forest in this illustration, was a slow-moving, plant-eating dinosaur that grew as long as 30 feet (9 meters) and as much as 2 tons.

在晚侏罗记的剑龙一样，像一双步行走过北美森林在这个例子说明，是一个缓慢的移动，植物为主食的恐龙生长长达30英尺（ 9米），以及重达2吨。

This paper reviewed its pathogenesis, forms, clinical manifestations, differential diagnosis, treatment and prognosis. Here a case of neonatal hypophosphatasia is reported. This baby was female (30 minutes old). Prenatal ultrasound showed disproportionate biparietal diameter and long bones of limbs in the baby. After birth, she presented with obvious craniomalacia, respiratory distress and cyanosis. Serum alkaline phosphatase level was significantly reduced. Both X-ray and autopsy showed extremely insufficient skeletal mineralization. Four days later she died of respiratory failure.

XC7201 is an interesting protein comprising 176 amino acids. Many sequences in the prokaryote and eukaryote kingdom with high similarity score were detected by BLAST search. It was predicted to a 3-hydroxyanthranilate 3,4-dioxygenase (3HAO), which is an extradiol dioxygenase that catalyzes the final conversion step of tryptophan to quinolinic acid in the kynurenine pathway.

XC7201由176个胺基酸所组成，比对已知物种资料库后发现在原核真核菌中都有类似的序列，其功能被预测为3-hydroxyanthranilate 3，4-dioxygenase (3HAO)。3HAO是一种双氧化酵素，在生物体进行把Tryptophan转变成Quinolinic acid的生合成途径中最后一个反应的催化。

The vascular bundle of stem is the type of double phloem. The anther is tetrasporangiate. Simultaneous cytokinesis in the microspore mother cell follows meriosis.

茎的维管束是双韧类型；雄蕊的花药四室，小孢子的形成为同时型胞质分裂，悬垂胎座，倒生胚珠，核型胚乳，果实成熟时胚仍处于球形胚阶段。

Younger artists, for example Lee Kit, Magdalen Wong, Enoch Cheung, Hanison Lau, Hei Ng Ka Chun, Otto Li, Tozer Pak, Tang Kwok Hin and Lui Long Tin have all recently produced three-dimensional work that touches on the absurd, often with a subtle political and social commentary.

年轻的艺术家们例如李杰、黄颂恩、张康生、刘学成、吴家俊、李天伦、白双全、邓国骞和吕朗婷，最近都制作了触及荒谬性的三度空间作品，当中通常也都带有一丝细微的政治社会评论。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
