物质控制

A recent mission of the EU's Food and Veterinary Office revealed serious deficiencies in the Chinese residue control system and problems related to the use of banned substances in the veterinary field.

欧盟的食品和兽医的办公室在中国发现了对严重残留物质缺乏的有效控制系统的问题和一些在畜牧方面使用了禁用物质的问题。

What then if one becomes independent on a chemical substance?Again,caregivers tend to take the easy way out.

但是，实际上，我们更注重铲除非法物质的存在，而不太注重控制个体对这些物质的渴求。

Turthermore, the technological measures in ensuring beer abiological Stability were given in the production of Saecharification, fermentation, filter and filling and package.

就啤酒酿造过程中的蛋白质、多酚、氧物质对啤酒非生物稳定性的影响机理进行了分析阐述，说明了高分子蛋白质和多酚物质是影响啤酒非生物稳定性的主要因素；并就糖化、发酵、过滤、灌装各生产工序提出了工艺控制措施以保证啤酒的非生物稳定性。

These are main problems of eutrophication.In this paper we selected alga that suits to grow under different concentration of nutrition, after selecting seed, domesticating, culturing alga purely in the lab, we gained Hydrodictyon reticulatum and microalga, most of which are Miorocystis and chlorella.

本文选取在不同营养水平条件下适合生长的藻类物种，在实验室进行选种、驯化和纯化培养，得到水网藻和微藻(主要为微囊藻Miorocystis、小球藻chlorella)；以实验室培养的生长速度快、生产能力高的水网藻为原料，制备一系列环境友好性光敏物质——叶绿素及其衍生物，运用光敏氧化分光光度法测定活性氧(O_2~-，H_2O_2，·OH，和~1O_2)，根据其光敏产生活性氧效率，进行光敏物质的筛选；选用叶绿素铜及其钠盐，以微藻为实验控制对象，以Cu~(2+)作培养对照，在相同光照、营养条件下进行控藻实验。

In the farm ecosystem of typical small basin, the ecological effects of complex inlaying structure of rice field and dry land were studied, the recycle and reuse of nutrients inside of system and the control of contaminants discharge of farmland eco-system were achieved through the re-distribution of nutrients.

对小流域农田生态系统开展了水旱田复合生态单元结构镶嵌的生态效应研究，有效地利用了物流通道的物质分配功能，实现了系统内部的物质循环与利用，控制了农田生态系统的污染物外排。

The nitrogen and pesticide in the topsoil with soil erosion go into river, lake and reservoirs and so on. So that the soil erosion reduced, the nocuous matter loss can be controlled as well, the sediment silt and water pollution in rivers, lakes and reservoirs can be decreased.

土壤中氮和农药等有害物质的流失是以水土流失为载体，进入江河、湖泊、水库等水源地，加大了这些水源地的污染，所以减轻了土壤水土流失量，就能够很好控制农耕地有害物质的流失，减轻江河、湖泊、水库等水源地的泥沙淤积和水质污染。

Results indicated that introducing some ring-structure into UF molecule during the synthesis could efficiently improve the water resistance of UF resin. The Uron ring would form if reaction temperature was more than 75 degrees C, and the higher Uron content was obtained at pH 8 and 85 degrees C in the absence of catalyst when the reaction time was long enough.

结果表明：通过在脲醛树脂合成中引入Uron环等环状结构物质能够有效提高脲醛树脂胶黏剂的耐水性；当反应温度高于75℃时，反应产物都生成了一定量的Uron环物质；在pH值为8左右、温度控制在85℃、不使用催化剂、尽可能延长反应时间的条件下，尿素与甲醛成环化反应生成的Uron相对值最多。

他们以126名15－17岁拥有物质依赖家庭史的个体作为实验组，以169名相匹配的没有物质依赖家族史的个体作为控制组。

The program includes customers, quotations, sales orders, invoices, receivables management, backorder management, vendors, purchase orders, receipts, bills, payables management, inventory control, physicaland non-physical inventory, stock replenishment, banking, bank reconciliation, general ledger, expanded reporting and analysis capabilities with over a hundred reports, e-mailing and exporting reports, a simple e-mail client, and security features.

该软件包括客户，报价，销售订单，发票，债权管理，负债管理，供应商，购买订单，收据，票据，支付管理，存货控制，物质的和非物质的存货，库存补充，银行业务，银行协调，总分类账，附加报告和带有大量报告的容量分析，电子邮件发送和报告导出，一个简单的电子邮件客户端，以及安全功能。

Plant volatiles can serve as attractants for specific pollinators, important cellular regulators in developmental processes and protection against environmental stress, whereas those released after herbivory or pathogen attacks can induce the expression a set of defensive genes or attraction of predators of the herbivores.

由於潜在的应用价值，近几年该领域颇受注目，特别是应用基因工程技术设计植物释放特殊气味物质，诸如特定的驱避剂或者其它控制植物或昆虫行为的特殊气味乃至与人类健康相关的药用气味物质。

The basic concept of FOP can be summarized as to further optimize effective prescription according to the standard of curative effects and with the aid of modern science and technology and theories of traditional Chinese medicine.

其基本内涵可概括为：以确有疗效的中药复方为研究对象，以现代科学技术和传统中医药理论为技术支持，以该复方所治病证的药效响应为评价标准，以优化重组疗效更优的新复方为研究目的。

Ever since our world has been a world, native forests have been indiscriminately exploited by man.

自从我们的世界一直是世界原生森林被任意剥削人。
