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.
