查询词典 tubular membranes

The gene launches a biochemical process in which a molecule called plasmin perforates the membranes of tissues, causing the membranes to break down and allowing the cancer cells to escape into the bloodstream and to adjacent tissues.

这种基因启动了一种生化过程，在这个过程中，一种叫做血浆酶的分子能够在组织膜上打孔，并导致膜降解，从而使癌细胞能够流窜到血管和临近组织。

In this contribution novel acid-base sulfonated poly(phthalazinone ether nitrile ketone)s membranes are introduced.The membranes are composed of SPPENKs as the acidic compounds,and polyetherimide as the basic compounds,furthermore,redissolving SPPENKs and PEI in N-methylpyrrolidone then cast directly onto clean glass substrates in dust free environment at 60℃ aiming at enhancing membrane toughness and other relative properties.

以合成的一系列不同磺化度的碘化聚芳醚腈酮为acidic聚合物，以聚芳醚酰亚胺为basic聚合物，并将其溶解在 N -甲基-2-吡咯烷酮中配成质量分数为10%的成膜液，60℃下刮制成膜，制得acid-base型磺化聚芳醚腈酮质子导电了聚合物膜。

Results: After cryofixation,basement membranes of skeletal muscle consisted of only one electron dense layer, T tubules were round, core cylinders were observed in terminal cisternae and there were thread-like protein particles on the membranes of terminal cisternae.

结果：冷冻固定后，缝匠肌基膜仅仅由电子密度高的一层组成；横小管为圆形；终池内含有电子密度高的环形物，终池膜上存在一排线状电子密度高的蛋白颗粒。

However after chemical fixation, basement membranes showed 2 main layers: the electron-lucent "lamina lucida" and the electron-dense "lamina densa"; T tubules were flat; there existed only some electron dense particles in terminal cisternae, the feet process projected from membranes of terminal cisternae toward T tubules.

化学固定后，缝匠肌基膜由两层组成：一层电子密度低，另一层电子密度高；横小管为扁平状或哑铃状；终池内仅有一些散在的电子密度高的颗粒，终池膜上有几个脚状突起伸向横小管。

Therefore,it is necessary to develop new routes to prepare anion exchange membranes without such chloromethylation process.As for cation exchange membranes, mostly-perfluorinated sulfonic acid ionomers,such as Nafion~ series,have been wildly used due to their high proton conductivity and substantial durability.

对于强碱性的阴离子交换膜的制备，由于传统路线中的卤甲基化步骤中不可避免的采用强致癌物质二氯甲醚，因此无论是从经济成本还是环境保护方面，开发不采用氯甲基化步骤的阴离子交换膜制备方法是目前的一个迫切要求。

The electrode showed comparable analytical performance in the micromolar range to Pb-ISEs with conventional poly-based membranes containing neutral ionophore and with solidstate membranes containing a mixture of lead sulphide and silver sulphide.

该电极显示比较分析的绩效micromolar范围以铅太阳能学会与传统的聚为基础的膜含有中性载体和固态膜含有混合物的铅和硫化物硫化银。

The effects of coating temperature,dry conditions and immersion time on the performance of membranes were systematically investigated through experiment in SiO2 inorganic membranes prepared by the solgel method.

通过实验考察了在用溶胶-凝胶法制备二氧化硅无机膜的过程中涂膜温度、干燥条件及浸没时间对膜性能的影响。

Within the single-ply market, there is a clear trend to switch to more environmentally membranes to the detriment of membranes like PVC.

在单层屋顶系统市场中，发展趋势显而易见，即具有环境危害性的卷材，如： PVC ，向更加环保的卷材材料转变。

Fourth, the membrane recovering method was found within stationary tubular membrane elements and was compared with rotating flow by using experiment, that is, the unloading pressure recovering method is one of the most efficient method, it may reduce the auxiliary time, such as washing , backflush, reverse filtration, but the tubular membrane is washed or backflush or changed after the cycle period are accumulated numerous times.

第四、对旋转流静止管式膜的再生进行了实验比较，并提出了旋转流膜管可以通过卸压再生，以减少膜管每次使用后的冲洗、反吹等辅助时间，采用该种方法再生的膜管其渗透通量完全能满足要求，当循环使用一定次数后再进行或冲洗或反吹或更换新膜管。
