中弱

Correlation coefficient: 0.9962 . Positively charged'free'complex ions should be readily quenched by 〓, but when it is bound to DNA, it can be protected from the quencher because the highly negatively charged 〓 would be repelled by the negative DNA phosphated backbone, hindering quenching of the emission of the bound complex.

从理论上讲，带正电的配合物的阳离子应该可以被大阴离子淬灭，但是在DNA存在下，金属配合物插入到DNA的碱基对中，而〓被带负电荷的DNA磷酸骨架强烈排斥，从而避免了〓的淬灭，因此大的Stern-Volmer曲线斜率相应于对配合物较弱的保护形式。D。

Photoinhibition is the major stress to submerged macrophytes because of its complete submarine feature.

如何解决沉水植被恢复过程中面临的水体光补偿深度低、水下光照条件弱的问题，目前还没有十分有效的技术措施。

physicochemistry experiment ; conductivity ; acetic acid ; weak electrolyte ; dissociate equilibrium ; constant

在实验教学中，也一直沿用这一方法，并将电导率的测定应用于弱电解质溶液离解平衡常数的测定[4 ，5] 。

The experimental results show that the interaction between polysilicic acid characterized negative charge and hydrolyzed aluminum species results in the decrease in the charge-neutralizing ability of PASC, in comparison with PAC.

研究结果表明，在 PASC 中，由于带负电荷的聚硅酸与铝水解聚合产物间的相互作用，使得 PASC 的电中和能力较 PAC 有所下降，其下降程度与 PASC 的碱化度和 Al/Si 摩尔比密切相关，B 值和 Al/Si 摩尔比越小，则 PASC 的电中和能力就越弱。

GnRH-ir fibers distribute in the various brain region from the olfactory bulb to the cerebellum. They are especially abundant in the hypothalamus, the preoptic area and the ventral telecephalon. The immunopositive reaction in precocious fish is evidently stronger than that in unprecocious fish, and there is only very weak reaction in the gonadal undeveloped fish. The differences are most obvious in the hypothalamus, but not in other areas.

性早熟大黄鱼的神经内分泌细胞对GnRH抗血清的免疫阳性反应明显，无论在细胞的数量和免疫强度都比未早熟鱼多和强，在性腺尚未发育的幼鱼脑中仅有弱的免疫阳性，这种差异在下丘脑外侧结节核及视前核处最为明显，在其它GnRH阳性部位则差异不显著。

O?C?Cu isotopes. revealing that the mixed hydrothermal fluid of magmatic water and meteoric water reactivated the ore elements in the carbonate rocks and quartz diorite. Copper was transported, as Clcomplexes in the ore fluid and precipitated to enrich and thicken the primary sedimentary protore.

认为该矿床是在岩浆水和后期少量大气水的加入而形成的混合热液共同作用下，活化碳酸盐岩地层和石英闪长岩中的铜等成矿元素，形成含矿热液，并以铜的氯络合物方式运移，在弱还原性条件下使原始沉积矿胚层加厚变富。

Experimental investigations on pulsant behaviors of particle flow were carried out on a two-dimensional spouted bed using PIV .

本文基于 PIV 处理颗粒流动图像获得了颗粒流动的瞬时速度；基于功率谱密度分布对瞬时速度的分析结果表明，喷射区轴线的中下部颗粒存在较强的速度脉动，环隙区颗粒速度脉动较弱；研究发现喷动周期与床体压力脉动周期基本一致。

Experimental studies were conducted at the Yucheng Comprehensive Experimental Station of the Chinese Academy of Sciences during the period from March to June in 2003 . Respiration of a pulverous sandstone soil was studied under cultivation of winter wheat over a growth season . Soil CH4 was measured by the Static-Chamber method combined with Gas Chromatography technique .

本文利用静态箱／气相色谱分析的方法，在中国科学院禹城综合试验站，对华北平原冬小麦生长旺季期间麦田土壤中CH_4气体通量进行了测定，试验起止时间为2003年3～6月，得出华北平原典型冬麦田土壤是大气CH_4的弱吸收汇。

Result The fruits of 5 tested sweet carambola cultivars had PPO activity. All PPO activity could strongly catalyze oxidative activity of pyrogallic acid, but they were very weak for the oxidative activity of chlorogenic acid.

结果］5个甜杨桃品种果实中测有PPO活性，该活性均强烈催化焦性没食子酸的氧化反应，但对绿原酸的氧化活性很弱。

Compared with therapeutic effect of Simvastatin, the effect of low-intensity laser rhinal radiation was weaker, however, it was effective and utilize the low-intensity laser radiation therapy on patients with abnormal liver function.

与舒降之相比，低强度镭射鼻腔照射疗法的调脂效果虽然相对较弱，值基於安全性的考虑，在饮食控制无效或肝功能异常的病人中使用低强度镭射鼻腔照射仍然具有一定的应用价值。

What would he tell Judith and the children?

他将怎样告诉朱迪丝和孩子们呢？

I this is at that time, the opinion with peacockish true girl is full of in a heart.

这就是当时的我，一个心中布满虚荣的女孩子真实的想法。
