落

Rain on the birdhouse, Rain on the pond, Rain on the doghouse, But not on me.

雨水落在小鸟舍上，雨水落在池塘上，雨水落在狗舍上，但是没有落在我身上。

Aiming at bottom roof caving and support impact problems induced with abrupt large scale caving upper roof in face 21303 of Daliuta mine, this paper put forward the motion parameter at roof caving and calculation formula of roof shear breaking force with the help of theorem of momentum, theorem of moment of momentum and D' Alembert principle. Roof caving process was simulated by Ansys Ls-DYNA program, and maxim impact force was got. The theoretical research outcomes in the paper were applied in face 21303 of Daliuta mine, and were accordant with actual observing status of roof caving process.

针对神东煤炭公司大柳塔煤矿活井21303综采工作面，上层采空区顶板突然大规模垮落对下层顶板及支架的突然冲击问题，文章采用动量定理、动量矩定理、达朗伯原理推出了顶板垮落瞬间的运动量及顶板切顶垮落所需要的剪力值计算公式，用ANSYS LS-DYNA程序对顶板垮落过程进行了数值计算，得到了最大冲击力，在大柳塔煤矿活井21303综采工作面对顶板垮落特征进行了实际观测和理论成果验证。

The basic characteristics of the whole process were gained. When the seedling falling out of the tube feet, the difference of the time interval between 2 neighboring seedlings wasn't notable, and the difference of the time interval of 2 neighboring seedlings wasn't notable and the agricultural time was not special notable. These results showed that the uniformity of the pneumatic ordered throwing transplantation was excellent and could meet the demands from design and agriculture; Upstanding state was primary as the seedling falling out of the tube feet, it showed that the seedling could keep erective preferably when the seedling falling to the field.

结果表明：钵体苗从导苗管管脚中落出时，相邻2株钵体苗落出时的时间间隔差异不显著，从左中右3个管脚落山的相邻2株钵体苗的时间间隔与农艺要求的时间差异极不显著，说明气力有序抛秧均匀性好，能满足设计要求和农艺要求；钵体苗从导苗管管脚落出时以直立状态为主，表明气力有序抛秧的钵体苗落入田间时能较好地保持直立。

In this technologically advanced era of our growth, but should be bold and out of the gap material desires to learn,"Chongrubujing busy to see pre-trial 花开花落, fate has no intention of Man With the outer Yunjuanyunshu "This is called" letting go "to mature.

在这个科技发达时代生长的我们，更应果断跳出物质欲望的沟壑去学习"宠辱不惊闲看庭前花开花落，去留无意漫随天外云卷云舒"这种名叫"放下"的成熟。

"Chongrubujing leisure, see Pretrial 花开花落; fate of not, with the outer Yunjuanyunshu Man."

"宠辱不惊，闲看庭前花开花落；去留无意，漫随天外云卷云舒。"

Chongrubujing leisure, see Pretrial 花开花落; fate not, Man with the outer Yunjuanyunshu.

宠辱不惊，闲看庭前花开花落；去留无意，漫随天外云卷云舒。

objective to investigate the existence of the erythropoiesis inhibitors.methods the present study included twelve undialyzed esrd patients with anemia.the sera from the uremic patients were added to cfu-e and bfu-e culture in the concentrations ranging from 1.25% to 5%.in vitro cfu-e and bfu-e growth in the presence of sera from esrd patients was compared with in the presence normal human subjects with the use of normal mice bone marrows.results the effects of the sera from uremic patients on cfu-e and bfu-e colony growth in concentrations ranging from 1.25% to 5% were investigated to be dose-dependent.the effect increased with the concentrations increasing of the sera（p＜0.05）.there were not significant inhibitory effect on the cfu-e and bfu-e growth of mice bone marrow in vitro from sera of the normal subjects.conclusion the erythropoiesis inhibitors exist in uremic sera which has a dose-dependent inhibitive effects on the growth cfu-e and bfu-e of normal mice bone marrow cells.

选择12例尿毒症肾性贫血未透析患者为试验组，另选正常健康体检者12例为正常对照组，将实验组、正常对照组血清分别稀释成不同终浓度，采用甲基纤维素细胞培养的方法对小鼠骨髓细胞进行培养，对比不同浓度血清组红系集落形成单位、红系爆式形成单位的集落数。结果在实验组中，与血清浓度为0的浓度组相比，与各浓度组血清共同培养的小鼠骨髓cfu-e和bfu-e的集落数均明显减少，且随血清浓度的增加，小鼠骨髓cfu-e和bfu-e的集落数逐渐减少，各浓度组间差异有显著性（p＜0.05）。结论尿毒症患者血清抑制小鼠骨髓红系祖细胞集落形成，随患者血清浓度的增加，抑制作用增强，具有剂量依赖性。

In the dynamics of total litterfall and litterfall components, there were seasonal variations and leaf was the basis. Nutrient content of most elements and litterfall have alike variational trends. Above-mentioned results exhibited that leaf had the conclusive influence on total litterfall and nutrient content.

总枯落量与枯落物各组成分均有季节性变动，且皆以枯落叶为主(70-75%)，而枯落叶与枯落物内多数元素的养分含量与其总枯落量有相似的变动趋势，以上结果显示枯落叶对总枯落量及养分含量有决定性的影响力。

Lives simply is theacademic honor benefits of rank and salary, the contempt appraises thehonor or disgrace, treats the humans affair with 平常心 the windand cloud transformation, the rise and fall, can maintain the soberbrains; Can like Wang Anshi,"the fear floating clouds not obstructlooks the eye, only reason body in topmost story"; Can like the Soviethorizontal wooden board on the front carriage body,"蓑 misty rain nomatter what always, also does not have the wind and rain to be alsoheartless", can look in front of the courtyard 花开花落, looks thespace cloud volume cloud to extend!

淡泊的是功名利禄，轻视的是褒贬荣辱，用一颗平常心来对待世事的风云变换，起起落落，才能保持清醒的头脑；才能如王安石，&不畏浮云遮望眼，只缘身在最高层&；才能如苏轼，&一蓑烟雨任平生，也无风雨也无情&，才能看庭前花开花落，望天上云卷云舒！

Then a sister moved to Pudong, he took another two-family houses rented out to someone else, another rent a room than he gave the landlord's rent more than a small white落了个Jin lived.

再后来妹妹一家搬到浦东，他就把二室户的另一间房子租给了别人，另一间房的租金比他给房东的租金还多，小靳落了个白住。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
