Adsorption of zn , pb and cd was significantly higher by fungi previously grown in substrate supplied with no3 ~ ( - ) - n compared with those grown in substrate supplied with nh _ ( 4 ) ~ ( + ) - n 此外，三种真菌之间在单位重量菌丝吸附和固持能力上也存在差异，而且因重金属的种类而异。
From the information available for the preparation to be assayed ( the “ unknown ” ) , assign to it an assumed potency per unit weight or volume , and on this assumption prepare on the day of the assay a stock solution and test dilution as specified for each antibiotic but with the same final diluent as used for the usp reference standard . the assay with 5levels of the standard requires only one level of the unknown at a concentration assumed equal to the median level of the standard 根据有效的信息制备试验溶液，指定一个假定的每单位重量的效价或者体积，然后在假设的基础制备当天储备液试验和稀释溶液作为每一种抗生素指定的效价，但是当使用相同usp参考标准品的最终稀释液时，试验应使用平行5的标准要求仅有一份未知的做为浓度等同于中部的标准。
Suffice it to say that in the modern era , processing , which , simply put , entails the transformation of relatively bulky perishable commodities into products that are more palatable , nutritionally dense , stable , and portable , and which , in so doing , increases the value weight ratio , was itself the object of revolutionary transformation 在现代，食品加工已成功地“将大量容易耗损的产品转换为更为可口的、富于营养的、稳定的和可搬运的商品” ，在这一转换中，食品加工还使得农产品单位重量的价值上升，并且还实现了食品加工业自身的革命性转型
Fourthly , set up the price theory model of the mould . combining the book of mould valuate method consult manual " and some actual conditions of mould factories , five kinds of methods : weight method ; man - hour method ; unit ' s weight method ; man - hour addition method ; similar comparative method are constructed and appraised 另外还建立了一些常用加工方法工时计算的数学模型；然后剖析了《模具计价办法参考手册》中的两种估价方法，工时法和重量法；针对覆盖件模具的特点，根据成都某模具厂的经验建立了单位重量法和工时累加法的数学模型。
