Two current biosafety research projects are studying the potential environmental impacts of cyanophycin potatoes.

目前有两个生物安全研究项目正在研究这种藻青素马铃薯对环境的潜在影响。

One component of cyanophycin is polyaspartate, which can be used as a biodegradable plastic. Polyaspartate binds calcium and therefore has potential applications in e.g. detergents as a water softener.

藻青素中有一种成分是聚天冬氨酸，这种成分可以用来生产生物可降解塑料，而且，聚天冬氨酸能够与钙结合，因此，还可以将之加入洗涤剂中作水的软化剂。

Biological activity of the compounds were studied and the result indicated that the compound 1,1'-ethyl dicarboxylate gem-dimethyl-cyclopropanediacylhydrazine has good activity against bean aphidsin at 250mg/L.

生物活性测定结果表明，在250mg/L的浓度下，化合物1，1'-二羧酸乙酯偕二甲基环丙烷双酰肼对蚕豆蚜虫有较好杀虫活性。

These vegetations appear in about 4% of SLE patients and rarely cause problems because they are not large and rarely embolize.

系统性红斑狼疮病人仅有4%出现，并且赘生物小不易脱落，因此对机体的影响较小。

Study shows that environment evolution and eustatic change of Holocene in this area may be divided into 6 stages:① early stage of early Holocene, 9 100~10 900 aBP,when sea level was low and this area was an oxidizing environment or oxidizing-reducing transition environment;② late stage of early Holocene, 8 000~9 100 aBP, sea-level rising,...

研究表明，本区全新世环境演化分为6个阶段：①早全新世早期，10900~9100aBP，海平面较低，尚未淹没本区，为近岸氧化环境或氧化—还原过渡环境；②早全新世晚期，9100~8000aBP，海水上涨，本区时淹时退，为浅海或潮坪环境，生物钻孔发育；③中全新世主体，8000~4150aBP，海平面快速上升，完全淹没，Fe2+/Fe3+介于0.7395~1.9123之间，为全新世中最高段，表明还原程度强、全球气候变暖；④中全新世后期，4150~2850aBP，海水有所下降，仍为浅海环境，Fe2+/Fe3+较高，多在1.0以上；⑤晚全新世，2850~1310aBP，海平面进一步下降，本区时常暴露，其中2150~1310aBP以还原环境为主，为潮下带，2150~2850aBP以氧化—还原过渡环境为主，为潮间带；⑥1855AD以来，海平面基本稳定，稍有上升，为现代黄河三角洲沉积时期。本区全新世至少存在5期冷热交替的旋回性气候变化。

This paper introduces an approach for locating an iris using integrodifferential operators based on the circular geometry of the iris.
