Below illustrate clapboard has spherule routine in the box of requirement of magical function.1 of the law in group 1 12 identical spherule put number for 1, 2, 3, in the box of 4, is what there is a spherule at least in asking every box different put a law how to many kinds there are?

下面举例说明隔板分组法的妙用。1 要求盒子中都有小球例1 把12个相同的小球放入编号为1，2，3，4的盒子中，问每个盒子中至少有1个小球的不同放法有多少种？

Everted sac experiments were carried out using viable segments of rat intestine for comparing mucoadhesive characters. The swelling behaviors were also examined and further investigation of release mechanism indicated that ketoprofen calcium pectinate gel beads were different from calcium alginate gel beads.

Results Ketoprofen calcium pectinate gel beads and calcium alginate gel beads showed excellent drug release pattern and mucoadhesiveness. Ketoprofen released from calcium pectinate beads mainly through diffusion behaviors, whereas the release of ketoprofen from calcium alginate gel beads was ruled by corrosion of carrier material.

结果 酮洛芬果胶钙凝胶小球和酮洛芬海藻酸钙凝胶小球均具有良好的生物黏附性能，果胶钙凝胶小球主要通过溶胀作用缓慢释药，而海藻酸钙凝胶小球的释药与凝胶小球慢慢吸水后骨架溶蚀有关。

A strip block is used instead of the ball to eliminate the measurement error caused by the trajectory deviation of the ball when passing the photo gate.And a spring clip is used to replace the electromagnet to eliminate the effect of remanence.

在单摆法中，要求忽视细线的质量且线长及小球尺度相比很大，把小球看成质点，并且小球的摆幅不能超过5°[1~3]；在自由落体法中，一般是用小球作为自由落体，但小球通过光电门时，往往不是小球的质心遮光计时，另外，钢球是用电磁铁通电后吸住的，由于断电的瞬间，电磁铁有剩磁，钢球不立即下落，并且钢球应吸在电磁铁的中心处，这些因素都会影响重力加速度的测量。

There was a plus relationship between NOS and bacteriolytic activity and a minus relationship between NOS and SOD as well as a minus relationship between bacteriolytic activity and AKP, which indicated that feeding Pediococcus acidilactici could significantly increase the activities of the immune factors in the shrimp body.

表明在饲料中添加适量的嗜酸小球菌（剂量10mg/kg）可使凡纳滨对虾体液免疫因子活力到达较高的水平；凡纳滨对虾血清中一氧化氮合酶对于嗜酸小球菌的添加量较为敏感，可作为评价嗜酸小球菌使用效果的指标之一。

Theurinary IL-6 level positively correlated with density of glomerular matrix membrane, global sclerosis, fiber or fibrocellular crescents and interstitial fibrosis (p. 05). According to the degree of density of glomerular matrix membrane and interstitial fibrosis, urinary Col-IV level had better correlation than urinary TGF-betal and IL-6 levels.In IgAN, Col-IV showed increased expression in diseased renal tissue whereas the site of expression of TGF-betal was mainly localized within the cytoplasm of tubular epithelial cells. Interstial expressionwas also present but glomerular TGF-betal expression was found only in patients with heavy mesangial proliferation. There was a significant correlation between glomerular positivity for Col-IV and severity of histological damage. There was also a significant correlation between positivity for TGF-betal and Col-IV in the tubular epithelial and interstitial lesions. In contrast, there was no ralationship between glomerular positivity for TGF-betal and severity of histological damage.The urinary TGF-betal level paralleled tubular TGF-betal expression.

结果 ①IgAN患者尿TGF-β1、IL-6、Col-Ⅳ水平较健康人明显增高(P＜0.01)，该变化与血中的浓度无关(P＞0.05)；②尿TGF-β1水平与小管间质TGF-β1阳性表达呈正相关(P=0.000)，而与小球TGF-β1阳性表达无关(P＞0.05)，尿Col-Ⅳ水平与小球和小管间质Col-Ⅳ阳性表达均呈良好的相关性(P＜0.01)，还与小管间质TGF-β1阳性表达呈正相关(P＜0.05)：③小球Col-Ⅳ阳性表达与肾组织慢性病变密切相关(P＜0.05)，小管间质Col-Ⅳ和TGF-β1阳性表达均与肾小管间质病变呈良好的相关性(P＜0.01)，而小球TGF-β1阳性表达与肾组织损伤无关(P＞0.05)；④尿TGF-β1、Col-Ⅳ水平与肾小球基质基底膜面密度、小管间质病变呈正相关(P＜0.01)，与小球内细胞数呈负相关(P＜0.05)，该结果与其在组织中的表达一致；尿IL-6水平浙江大学硕士学位论文尿TGF一B一、IL一6和Col一IV在IgA肾病中的应用价值与基质基底膜面密度、球性硬化、纤维或细胞纤维新月体所占肾小球百分数及小管间质病变均有显著的相关性(F.05)；在轻度肾病理损伤时，尿'l'G卜pl、I卜6、Col一IV水平即升高，而尿Col一W在反映细胞外基质积聚和间质纤维化程度上比尿TGF一pl和IL一6有更好的相关性。

The influences of drug entrapment efficiency and drug release properties were investigated. Everted sac experiments were carried out using viable segments of rat intestine for comparing mucoadhesive characters.

vanced a new approach to measure the coefficient of viscosity with the method of falling balls , and explained the movements of falling balls of the same diamters in viscose fluid in tubes of different diameters and falling bahs of different diameters in viscose fluid, as well as the whole process of movements of falling balls in viscose fluid.

I remember there was a little story let me ponder for long: five fingers to fight because they are the length of missing, one has to compete against, so they thought of a way, that is, brought a small ball, who should pick up the ball Who is the winner, when the brothers worked hard, want to first pick up the ball, but the days of the later, no one can pick up the ball, the brothers who are very dull of mind, the weakness of their own , complaining, criticism, feel that they are no use, nothing to do anything, the brothers who no sleep a night and, after the anti then, the next morning, the sun out of the ground plane of that moment, brothers say in unison:"We test with the next bar."

记得曾经有一个小故事让我深思良久：五只手指头打架，因为它们长短不齐，却要一争高下，于是它们想到了一个办法，就是拿来一个小球，谁先拿起小球谁就是赢家，那时几个兄弟奋力拼搏，都想先拿起小球，可是日子一天天的过去了，谁也没能拿起小球，兄弟们的心情都十分沉闷，对自己的软弱无能，抱怨，批评，觉得自己很没有用，做什么都一事无成，兄弟们一晚都没睡好，辗转反则，第二天清晨，在太阳跳出地平面的那一瞬，兄弟们异口同声的说：&我们一起试下吧&。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。
