Result The study showed that there were two isozymes of serum amylase including Amy-1 and Amy-3 in Qinghai Alectoris graeca.

结果］青海石鸡血清淀粉酶有Amy-1，Amy-3 2种同工酶，其中Amy-1有AA、AB和BB 3种表型，表型频率分别为17.95%、66.67%、15.38%；AB为优势表型，Amy-1和Amy-1等位基因频率分别为0.5128和0.4872，基因杂合度为0.4997、青海石鸡血清淀粉酶活性为(566.62±112.20)U/L。

Numbers near the branches were bootstrap probability values coming from 1000 replications. Some bootstrap probability values were 92%(Coturnix chinensis/ Coturnix japonica), 100%(Tetraogallus altaicus/ Tetraogallus himalayensis), and 100%(Tetraogallus altaicus/ Tetraogallus himalayensis/ Tetraogallus tibetanus. The overall average distance was 0.112, and average genetic distance among Tetralgallus was 0.042. The genera Alectoris, Coturnix, Tetrao-gallus and Pucrasia formed a monophyletic group.

结果表明：日本鹌鹑和蓝胸鹌鹑的BP值为92%，阿尔泰雪鸡和喜玛拉雅雪鸡(T.himalayensis)的BP值为100%，(阿尔泰雪鸡、喜玛拉雅雪鸡)和藏雪鸡(T.tibetanus)的BP值为100%；石鸡属、鹌鹑属、雪鸡属和勺鸡属组成一个单系群；石鸡属和鹌鹑属的共同祖先与雪鸡属的祖先是姐妹群。

The sharp difference suggests that they have different origins: the former comes from allochthonous sapropel-type organisms of the lower strata and is the remains of crude oil, and the latter is autochthonous humic-type organic matter of sedimentary rocks between the basalt layers.

玄武岩中铜矿石沥青的δ13CV-PDB为-27.3‰～-33.2‰，平均-31.97‰，沉积岩中铜矿石碳质的δ13Cv-PDB为-20.2‰～-23.2‰，平均-22.11‰，表明二者无明显成因联系，前者属腐泥型，为石油的遗迹，来自下部地层；后者为腐植型，来自原地沉积的陆生高等植物。

AACS (alveolate aluminum compound stone) is a high-class construction and decoration materials which usually be used at exterior wall. It was used in the spaceflight industry field.

铝蜂窝复合石系列，蜂窝铝复合石是一种外墙高级建筑装饰材料，过去只是用于要求很高的航空航天工业。

S. halepense, Pennisetum purpureum, Saccharum arundinaceum, P. purpureum typhoideum, Andropogon gayanus had a leaf vitamin C content ranging from 256.67 to 319.53 mg/kg; S. halepense and Neyraudia reynaudian had the highest leaf soluble saccharides content, about 125 g/kg.

石茅、矮象草、斑茅、王草、甘巴草叶片维生素C含量在256.67~319.53 mg/kg之间，与其余供试植物叶片维生素C含量差异显著；石茅、类芦叶片可溶性糖含量最高，在125 g/kg左右，与其余供试植物叶片可溶性糖含量差异显著。
