Comparing size distribution of trace elements at haze weather and the normal weather discovered that,Ca、Ti、Fe、Cr showed significant enrichment in the small size particle at the haze weather:Cu,As didn't have different at such two kind of weather conditions;Zn、Mn、Pb appeared bimodal even trimodal distribution,whose suggested that there were a long distance transmission in originations of such three metals.

对比正常天气下的金属元素的粒径分布，发现：Ca、Ti、Fe、Cr 等元素在灰霾发生时细粒径上有明显的富集： Cu、As 在两种天气条件下区别不是很大：Zn、Mn、Pb 等元素在两种天气条件下均出现双峰甚至多峰分布。由此推断 Zn、Mn、Pb 的来源中可能存在长距离传输。

This paper has studied preparation of Grignard reagents under phonochemistry and optimum technologic conditions is: the power of ultrasonic is 500W and frequency is 250KHZ, having twelve energy conversion devices, water bath temperature being 20C, solvent being THF,unstirred.

Anti-filament immunofluorescence indicated the distribution of primary vestibular neuron endings in vestibular sensory epithelium and the contacts between it and hair cells were normal.These results indicated that Smad4 conditional knockout mice were generated successfully, whose morphological and pathological changes in vestibulum auris internae were slightly.

该研究提示，软骨组织Smad4条件基因敲除小鼠动物模型造模成功；Smad4条件基因敲除小鼠的内耳前庭形态轮廓基本正常但细节上有一定程度的畸形，纯合子小鼠前庭末梢感受器病理改变轻微。

DRG co-cultured with sciatic nerve undergoing Wallerian degeneration for 14 days in vivo in serum free DMEM/F12,1 sciatic nerve segment was added into co-culture system at the first moment, the axons were strong and straight and could adhered to each other, and the number of axons dramatically reduced compared with that of DRG cultured alone in serum free medium.

分别在无血清和有血清的条件下将新生鼠的背根神经节和体内变性14天的大鼠坐骨神经段进行联合培养作为实验组，并以在相应条件下单独培养的DRG的轴突的生长情况作为对照组来观察比较轴突的生长情况。

2DRG co-cultured with sciatic nerve undergoing Wallerian degeneration for 14days in vivo in serum free DMEM/F12,1sciatic nerve segment was added into co-culture system at the first moment,the axons were strong and straight and could adhered to each other,and the number of axons dramatically reduced compared with that of DRG cultured alone in serum free medium.2DRG cultured in serum free DMEM/F12for 4days,then the sciatic nerve segment was added into the culture system for 3days,the axons became straight and part of them adhered to each other.

The wear mechanisms of the graphite pairs were examined based on the original image before and after sliding, the result shows that under air media, the graphite pairs works on the conditions of boundary lubrication and the wear mechanism is dominated by adhesion and plough wear, which is dominated by slightly plough wear under water environment.

磨损表面原始形貌对比分析表明，在空气中，摩擦副表面处于边界润滑状态，主要磨损机制是粘着磨损和犁削；水润滑条件下为轻微犁削；油润滑条件下，摩擦副表面处于为边界润滑和流体润滑状态，油中的减摩剂对试样表面有抛光作用。

While it is generally acceptedthat long day is needed for bulbing,there are some reports of garlic stocks bulbing under shortdays after low temperature treatment.

一般认为长日条件是鳞茎形成所必须的；而有试验表明，种蒜经低温处理，在短日条件下也可以形成鳞茎。

Complete liberty of contradicting and disproving our opinion, is the very condition which justifies us in assuming its truth for purposes of action; and on no other terms can a being with human faculties have any rational assurance of being right.

我们之所以可以为着行动之故而假定一个意见的真确性，正是以有反对它和批驳它的完全自由为条件；而且也别无其他条件能使一个象具有人类精神能力的东西享有令他成为正确的理性保证。

But science neither simply opposes against metaphysics nor simply merges with it, their relationship is complex: they are interdependent, interpenetrated, mutually conditional, mutually conductive, and work in coordination, at the same time, they are mutually exclusive, and hold each other back. Besides these harmful influence and positive contribution, there're more other interactions in varied dimensions, which are determined by specific scientific theory and specific metaphysical one.

本文认为，形而上学是科学之所以可能的一个主体条件，同时又是科学发展的一个限制性条件，但是，科学和形而上学之间既不是简单的融合也不是简单的对立，它们的关系具有复杂性：科学和形而上学既相互渗透又互相反对，既相互制约又相互诱导，其作用方式和作用效果又是多重的、有差别的、复杂的，这既取决于具体的科学理论又取决于具体的形而上学学说。
