Based on the analyses of the co-relationship between additional requirements of bilge pumping arrangements and requirements of subdivision and damage stability for passenger ship s,the authors found the irrationality of bilge pump number being as the margin for additional requirements of bilge pumping arrangements and proposed amendments to the new regulation 35-1 on bilge pump.

简要介绍了修改后的SOLAS第Ⅱ-1章第35-1条有关舱底排水设备的修改内容；通过对客船舱底排水设备附加要求与分舱、破损稳性要求之间相关性的分析，认为以舱底泵特征数作为设置舱底排水设备附加要求的临界条件是不合理的，从而对该部分内容提出了修改建议。

Check the chromogen / substrate solution, the simplest test method is to mark a drop of antibody enzyme substrate added to the preparation of a good solution, if desired substrate color change occurs, you can rule out the substrate factors.

检查色原/底物溶液，最简单的检测方法是将一滴标记有酶的抗体加入到制备好的底物溶液中，如果底物发生预期的颜色变化，则可排除底物的因素。

The results showed that all components had low substrate affinity for CMC, and V〓 can be reached only at higher substrate concentration. The K〓 value of βglucosidase to salicin is 0.2%.

通过对各酶组分动力学参数的测定，五种内切酶对底物CMC-Na的Km值分别为（从EGⅡ-1到EGⅣ）；6.8％、4.6％、6.8％、8.7％和5.9％，说明这五种内切酶对底物的亲和力较小，需要在较高的底物浓度下才能达到Vmax；β-葡萄糖苷酶对底物水杨素的Km值为0.2％。

The biocatalyzed characters of the purified cellulases were investigated with the CMC-Na as substrate. The most appropriate catalyzed temprature for cellulase 1 is 60 "C,and 65 for cellulase 2. The two enzymes have the extreme stability at the temperatures no more than 50.The CMC-Na has the protective effect on the cellulase. The pH stability range of cellulase 1 is 4 ~ 8, and 6-9 for cellulase 2. Zn2+, Ca2+, Mg2+, K+, Li+can ativate cellulase 1. K+, Li"1 can ativate cellulase 2. Cellulase 1 can mainly decompose CMC and salicin. Cellulase 2 can decompose not only CMC and salicin, but other substrates feebly.

以羧甲基纤维素为底物时，酶1的最适催化温度为60℃，酶2的最适催化温度为65℃，在50℃以下稳定性较好，底物对酶有较强的保护作用；酶1和酶2的最适pH分别为5.5和5.5～6.0，酶1的pH稳定性范围为4～8，酶2的稳定性范围为6～9；Zn~(2+)，Ca~(2+)，Mg~(2+)，K~+，Li~+对酶1有激活作用，K~+，Li~+对酶2有激活作用；酶1主要对CMC和水杨素有分解作用，对其它底物几乎不分解；酶2除了可以分解CMC和水杨素外，对其它底物也有微弱的分解作用。

This paper reviews the methods and recent progress in cold seep benthic foraminiferal studies in some modern active cold seeps. Through comparison the main characteristics of modern cold seep benthic foraminiferal faunal and the discrepancy between different seepages are presented. It also reviews the carbon isotope response of benthic foraminifera in different cold seep areas and its possibly influential factors. Finally we give a general outlook for the study of cold seep benthic foraminifera in the northern South China Sea.

综述了全球一些主要冷泉区的底栖有孔虫研究方法及其进展，对比了各冷泉区底栖有孔虫群落结构的主要特征及地域差异，评述了冷泉区底栖有孔虫的碳同位素记录特征、影响因素及其对冷泉活动的潜在指示意义，最后提出了南海北部冷泉活动区底栖有孔虫方面的研究展望。

Anti-rust paint with zinc yellow, iron oxide red epoxy resin primer, the film tough durability, good adhesion, if used in conjunction with the ethylene phosphate primer can increase the heat resistance, salt spray, making them suitable coastal areas and warm tropical metal grounding.

防锈漆 有锌黄、铁红环氧脂底漆，漆膜坚韧耐久，附着力好，若与乙烯磷化底漆配合使用，可提高耐热性，抗盐雾性，适用沿海地区及温热带的金属材料打底。

The 120m3 BF foundation temperature is reduced from 950℃ to below 700℃ and the furnace life campaign is prolonged for more than 2 years by taking furnace maintenance measures such as batching schreyerite in burdens to deposit Tion hearth bottom to form a steady protective layer and make molten iron liquidity slower to slowdown the erosion on bottom, drilling holes to lay water-cooling pipes in heat resistant foundation to heighten the 1150℃ isothermal line of molten iron to make frozen metal layer thicker.

对济钢120m3高炉炉底侵蚀状况，在生产中配加钒钛矿，使其还原成Ti的沉积，以对炉底形成稳定保护层，降低铁水流动性，减缓铁水对炉底冲刷；同时在耐热基墩打孔，穿埋水冷管，促使炉缸铁水1150℃等温线上移，凝固团增厚。实践表明，特护期间炉基温度由950℃下降至700℃以下，炉役寿命延长2年以上。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.
