Abstract:Effects of starch, salt, water content and heating condition on the texture of minced fish (Silver Carp) gel were studied. The suggested Contents of starch, salt and wa- ter were 10%. 3%. 10%. respectively. With the discussion of heating, a proposed model

Abstract:在0.1mol/L NaNO_3和适量十六烷基三甲基溴化铵(CTAB)介质中,采用玻碳汞膜电极作为工作电极,差分脉冲阳极溶出伏安法测定金属Pb的增敏效果可达10倍左右,其溶出峰为-0.47V(V.S.Ag/AgCl 1mol/L KCl),线性范围为0～100ppb,其准确度和回收率分别在4.6%～9.9%和92%～114%之间。

Abstract:用组织化学定位法证实了速冻两个月(-20℃)草莓中存在有活性多酚氧化酶,且主要存在于除去线粒体的上层清液中。用分光光度法测定了它的花色素苷、类黄酮和总酚含量。研究了多酚氧化酶活性的影响因素及最适条件,并测定了7种抑制剂对酶活性的影响。

Abstract:采用物料平衡的方法导出了碳平衡间接测定菌体浓度的计算公式,并用实验结果进行了验证,结果发现通过碳平衡间测定菌体浓度的计算值与实测值误差甚小,证实了碳平衡法间接测定菌种浓度的可行性,从而解决了粗料发酵生产柠檬酸过程中菌体浓度难于测定的问题,为建立柠檬酸发酵数学模型打下了基础。

Abstract:运用原生质体融合技术成功地将杀伤质粒转入啤酒酵母中,并使其能十分稳定地表达杀伤性能。经发酵试验确认胞质融合株kSC-2_f-11具有与亲株相似的发酵性能。所生产出的嫩啤酒与亲株相似且能保持较长时间的杀菌活力。

Abstract:Some physical properties and structural characteristics of wheat starch graft copolymer with polyacrylamide were studied. The experiment results Showe that the ther- mal behaviour of this product is different from the native starch, and its gelatinization

Abstract:A two-stage Computer measurement system of sizing machine and the sizing technology optimization are introduced. The software, hardware and the parameter mea- surement for sizing procedure are described, The optimization design for sizing procedure are di

Abstract:A method of quatitative digital display in measuring the depth of surface crack on the steel products is introduced. The principle of harmless detection, eg, alternative potentiometry, injecting the alternative current signal into measurement sensor's hea

Abstract:By combining the Kane's method with the tool of graph theory in Roberson/ wittenbery formalism, formulates the dynamical equations of multirigid-body systems with tree structure, The form of obtained equations is concise. It can reflect explicitly the str

Abstract:It has been proved mathematically, that the string vibration will forms standing waves if its Uper end is fixed while lower end moves round a circle. The study of the shapes, sections and tension of unwinding balloom must be based upon the theory of strin

Abstract:In this paper, we discuss a class of correlated random walks with two elastic barriers. For this class of walks we derive some expressions of the absorbing probability generating functions at the nth step. These results make the corresponding ones in [S,
