D. 400.Scholars and scientists, including Alfred North Whitehead, have argued that Christianity, rather than impeding science, provided an essential prerequisite for its development, the belief that nature behaves in a regular and orderly manner.

选择进化论的原因有二，首先对基督教来说，它可能是迄今为止来自科学的最大挑战，事实证明它们之间完全能够化合；其次，它与基督教间张力的消解和激化都有经典的事例，因而能非常充分地体现出舆论氛围的重要性。

The groups have also invested in antimalaria drugs for ACT, artemisinin-based combination therapy.

这些组织还投入研究抗疟疾药物ACT，基于青蒿素的化合治疗方法。

According to the principle of continuity of wave function, when different elements react with each other to form compound, the electronic densities of atoms at interface must be equal. Each atom should change the atomic radius to shift their electrical density, then this made huge micro-stress in atoms.

在单质元素原子形成化合物时，由于要满足量子力学的波函数连续原理，要求原子界面上的电子密度相等，各原子在化合时必须通过改变原子半径以达到相同的原子边界电子密度，从而在原子中产生了很大的微观内应力。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
