材料化学方面的 Briefly the catalyst charge was ca.2 g with an average particle size from 16 to 32 mesh.这句话盖怎么翻译,谁能帮下.
原段落是 The catalysts were tested in a fixed-bed flow microreactor.Briefly the catalyst charge was ca.2 g with an average particle size from 16 to 32 mesh.The catalyst was activated for 1 h at 550 ◦Cunder nitrogen and then cooled in nitrogen to the reaction temperature.Catalytic tests were carried out at 120 ◦C under 1MPa.The reaction products were analyzed by a GC-8A gas chromatograph with an FID detector.The conversion of ethylene and 2-butylene was calculated on the basis of carbon number.

据我所知,P是-3 charge ,然后CL是-1 charge.5氯就变成CL5.就是-5 charge了,然后个负charge的元素怎么弄在一起?

请问：分词表伴随
第一句：He cane charging out of the kitchen.(charge out of意为冲出）在这句中,charging out of是什么用法?是表伴随?
第二句：She went into the house and later came out bundled in raincoat.在这句话中,bundled in raincoat 是表伴随吗?
是不是表伴随的分词都用逗号跟句子隔开?我看例句都是这样的.所以以上两句是吗?如果不是,是什么?

3.2.Operating variables and feed charge composition effect on energy efficiency factor
In order to optimize the cement clinker grinding operation,the sensitivity of the energy efficiency factor,defined by the production of 3500 cm /g specific surface area per unit of specific energy consumed is studied under various grinding operating conditions and feed charge compositions.It must be noted that most of the experiments were carried out keeping constant the gypsum composition (4.5%).This composition is commonly used in the cement clinker industry.Fig.4 shows the effect of operating parameters on the energy efficiency factor.Each parameter was varied in turn,keeping the other parameters constant and using crude cement clinker for the feed charge.The mill speed (Fig.4a),the material load (Fig.4b) and the ball load (Fig.4c) have nearly the same effect.The energy efficiency factor increases till a maximum value and decreases then.For these parameters,the maximum value obtained is 36 cm /J.The average composite ball size seems to have the strongest effect (Fig.4d) with a maximum energy efficiency factor value equal to 39 cm /J.It is generally observed that the rate of size reduction in tumbling ball mills depends on the rate of collision between the grinding media,the probability of capture of feed particles between the balls andthe probabilityoffractureof the captured particle [14].Investigating the effects of the powder and ball charge filling on the grinding of quartz in a laboratory ball mill,
Shojietal .[9] found that U=0.83 and J=0.15 were the optimum conditions for the maximum breakage rate at minimal specific energy consumption.As shown in Fig 4b and c,the optimal grinding values U=0.75 and J=0.38 obtained for maximal energy efficiency factor are different.These operating conditions probably cause less coating of the powder on the balls and the wall mill.Concerning the effect of the rotational speed (Fig.4a),the optimum is obtained for N=65 rpm (corresponding to about 60% of the critical speed).Yang et al.[15] have reported similar results for runs performed in a laboratory ball mill also equipped with efficient lifter bars for which the fraction of energy available to cause breakage by tumbling is maximal.Moreover,it is shown (Fig.4d) that the 24 mm optimal ball size corresponding to a maximal energy efficiency factor and concerning the crude material (having more than 50% less than 355 μm) does not coincide with the size calculated by the maximum breakage rate relationships [13].So,it is concluded again that for this crude cement clinker material the energy efficiency factor can be optimized using operational conditions corresponding to relatively low breakage rates.

Most lightning takes place within a cloud when the charge separation within the cloud collapses.However,as the storm cloud develops,the ground beneath the cloud becomes positively charged and lightning can take place in the form of an electrical discharge between the negative charge of the cloud and the positively charged ground.so even though it represents only 20 percent of all lightning,it has received a lot of scientific attention.
题目问作者为什么提到【Lightning that strikes the ground is the most likely to be destructive】,
我选的选项是：explain why scientific of this form of lightning is very important
正确答案是：explain why this form of lightning has been investigated so much
