微弱

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。

To solve the problem of identifying weak signals with large parameters,principle of stochastic resonance is studied.Conception and realization of scale transformation stochastic resonance are proposed.

为解决大参数微弱信号的识别问题，在研究随机共振基本原理的基础上，提出了变尺度随机共振的概念并给出了实现方法。

Other times smog works its magic, and the whole world is seen through an opal haze, faint and flower-tinted, so that docks, ships' masts, wooded headlands, monster buildings with cranes scissoring the sky, even the diabolic BP tanks, assume the mysterious beauty of a mirage.

还有时候，烟雾玩儿起魔法，让整个世界都笼罩在蛋白石色的光晕中，微弱，却如花朵般色彩斑斓，码头、桅杆、树木茂盛的海岬、巨型建筑以及裁剪着这城市天空的起重机、甚至是魔鬼般的 BP 贮水池都呈现出海市蜃楼般的迷幻美。

His Age of Diminished Expectations and Peddling Prosperity filled the gap between the boringly descriptive genre of "up-and-down economics" books and sensationalist and shallow "airport economics" books.

他写的《期望灭失时代》（ Age of Diminished Expectation ）与微弱繁荣的时代，填补了枯燥乏味地描述经济波动的经济学书籍，与标题党式的、浅陋的、在机场出售的经济学书籍之间的鸿沟。

Shake off all the fears of servile prejudices, under which weak minds are servilely crouched.

抛下所有奴性偏见的恐惧，在那里微弱的心灵奴婢般地蜷缩著。

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

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
