中弱

The three isomers structures of 3 were discussed in detail based on the calculation results. Among the six bonds in 3, the P_O bond between the phosphorus and carboxyl oxygen O3 was the weakest one, and could be easily broken to form a new penta-coordinate intermediate 4 which could yield the phosphoryl N → O migration product 5 by breaking the weaker P_N bond.

在六配位磷中间体3的6根键中，丝氨酸的羧基氧O3与磷之间的键最弱，最易断裂生成新的五配位磷中间体4， 4的P_N键断裂得到磷酰基的N→O转位反应产物5。

The lowest level of sonority, the pianissimo, must also be totally effortless in its production.

钢琴弹奏中，就是最低的音量，极弱，也必须是要在完全轻松的情况下弹奏出来的。

The plainness also reflects the poor position taken by the Chinese brands in competition.

中国的 LOGO 之弱同样也反映了中国品牌在竞争中的某种弱势。

A weakly magnetic black mineral found in metamorphic and plutonic rocks; an iron titanium oxide in crystalline form; a source of titanium .

一种具有弱磁性的黑色矿物，见于变质岩和火成岩中，晶体状铁钛氧化物，是钛的来源。

A weakly magnetic black m ral found in metamorphic and plutonic rocks; an iron titanium oxide in crystalline form; a source of titanium.

一种具有弱磁性的黑色矿物，见于变质岩和火成岩中，晶体状铁钛氧化物，是钛的来源。

The effect of anchoring energy on the pretilt angle was considered for the first time in this thesis. The relations between pretilt angle and polar anchoring energy, also and effective twist angle were discussed.

本文首次考虑到锚定能的影响，给出了预倾角与极向锚定能和有效扭曲角的关系，发现在弱锚定条件下，增大扭曲角和降低极向锚定能都导致预倾角低于均匀盒中的数值。

This complex reaction was phenolic electronic substitution reaction, so reaction rate was related with the positive electricity of pro-electronic reagent, as well as the form of aromatic hydrocarbons. Rates of chlorination of phenol and 2-monochlorophenol were faster in alkaline water than that in weak acid water, so 2,4-dichlorophenol and 2,4,6-trichlorophenol formation concentrations increased with the reaction time.

该复合反应属于酚类电子取代反应，反应速率与亲电子试剂的阳电性以及芳香烃的形式有关，碱性水环境中氯取代苯酚和2-一氯酚的速率要快于在弱酸性水环境；随着pH的升高，2，4-DCP和2，4，6-TCP的生成浓度也不断增加。

A substance or factor that will not promote cancer by itself but can potentiate cancer when acting with carcinogenic agents.

科学家们怀疑酒妨碍了身体将烟中的致癌化学物质转化成毒性较弱的物质并加以清除的能力。

There are two types of predicative problems about the practical predication in the engineering application,one is called the well－structured problem,another is called ill－structured problem.

在工程应用的实际预测中，主要有两类不同性质的问题，一类是强结构化问题，另一类是弱结构化问题。

So, primary proton event can be identified effectively from the hybrid experiment results by use of ANN (with less dependence on interactive model), and a ideal primary proton energy spectrum will be obtained.

因此，ANN方法对模型的依赖性较弱，预计利用这一方法可以有效地分辨出联合实验中的原初质子事例，从而得到一个理想的质子原初谱。

I can not make it blossom and suits me

我不能让树为我开花

When temperatures are above approximately 80 °C discolouration of the raceways or rolling elements is a frequent feature.

当温度高于 80 °C 左右时，滚道或滚动元件褪色是很常见的特征。
