According to the year with the best large-seed production, the reasons for empty seeds could be estimated as follows: Seed potential per cone calculated as 2 times the number of fertile ovuliferous scales was about 206 seeds. Percentages of seed losses resulting from pre-and post-pollination ovule abortion, prezygotic factors, embryo degeneration, and efficient seed were 33%, 27%, 39%, and%, respectively.

依据大粒种子产率最高的1年来估测空粒种子产生的因素，可以推估如下：依据每个可孕性鳞片所含2粒种子的鳞片数，潜力种子数约有206粒，再依此值算出受粉前后胚珠败育率、受精前败育率、胚败育率、及有效种子率分别为33%、27%、39%及%。

Today, in the foreign intelligent artificial leg, the executive mechanism which controls the bent and stretch"s movement of knuckle and the pendular movement of calf is a single air cylinder. In the air cylinder, there is a throttle, the cylinder"s damp can be adjusted by controlling the opening of the throttle valve, when the air cylinders damp changes, the pendular speed of calf will change too.

目前，在国外研制成功的智能人工腿中，控制膝关节屈伸运动及小腿摆动的执行机构是一个单级空压气缸，其内有一个针阀，通过调节针阀的开度可控制气缸阻尼，从而控制小腿摆动的速度。

He that seeketh victory over his nature, let him not set himself too great, nor too small tasks: for the first will make him dejected by often failings; and the second will make him a small proceeder , though by often prevailings .

记得初来时，我在小巷中穿论，本性则会变得不那么举重若轻了；而若是形成了习惯，本性就可被改变了。想要战胜本性，人必须给自己确立不好高骛远而又不徒托空言的目标。而还要注意的是，其一，不要为经常的失败而懊恼；其二，把它看作一件小事，即使它很难。

The pseudopodial movement could be inhibited by calcitonin (100 μg*L－1). Lacuna formation could be found in cocultured specimens. There were fibrils on the walls of lacunae. The MGCs demonstrated positive reaction with Gomori stain. Conclusion: The results demonstrated that MGCs had the same morphological features and the bone resorption ability as the osteoclasts.

结果：倒置相差显微镜下可见多核巨细胞胞核较多（20个以上），胞浆周边不规则，有伪足样突起；胞浆内可见较多大小不等的空泡；降钙素（100 μg*L－1）可抑制多核巨细胞的伪足样运动；多核巨细胞与灭活的骨片共同培养时可见骨吸收陷窝形成，扫描电镜下可见吸收陷窝底面有原纤维；Gomori染色时可见多核巨细胞的酸性磷酸酶呈阳性。

Electron micrograph showed us that hepatocytes were damaged seriously along with the prolonged NHBD time in A group. At the NHBD 120 and 150min in A group, hepatocytes showed numerous cytoplasmic vacuoles and lysosomes, round swollen mitochondria with clear matrix and rough endoplasmic reticula which was not in a stacked arrangement.

电镜发现，A组随着心跳停搏时间的延长，肝细胞的损伤逐渐加重，至120和150min时，肝细胞内可出现大量空泡和溶酶体，线粒体和粗面内质网结构也遭到破坏，但未出现明显的坏死和凋亡改变。

Although some studies have reported an incidence of calcification as high as 25 to 30 percent, others have identified it far less often. When calcification is present, however, the roentgenographic pattern most often resembles popcorn, a finding that is almost diagnostic. The presence of fat and calcium make the CT diagnosis exquisitely accurate. In a report of 47 lesions studied by CT, 30 (63.8%) contained fat only (n=18), calcium and fat (n=10) or calcium alone (n=2). Thin sections must be used to identify fat with certainty.

虽然有的研究报道钙化率可高达25 ~30 %，也有的报道远小于此，但是当钙化出现时，常表现为爆米花状，脂肪和钙化的出现在CT显示精确，在一个47个病灶的CT研究中，30个63.8%含有脂肪，10个含有钙化和脂肪，2个仅有钙化，要显示脂肪成分，必须用薄扫，由于部分容积效应，当层厚教厚时，小的空腔容易与脂肪混淆。

Under inverted microscope, stereognosis of neurons died down, there were blank bulb in the neurons, dark particle were seen in the neuritis; the result of MTT test showed that the survival rate of neurons was obviously decreased. Res 40μmol/L increased the survival rate of neurons. Aβ(subscript 25~35) dose-dependently increased the level of MDA, decreased the level of GSH. Res dose-dependently increased the level of GSH, decreased the level of MDA.

结果：Aβ(下标 25~35)在终浓度为2μmol/L时神经元形态有明显的变化，细胞立体感减弱，胞体内空泡形成，细胞突起内可见黑色颗粒状物；细胞的存活能力明显下降，与对照组相比较有显著性差异(P.05)；Res在终浓度40μmol/L时，能明显提高细胞的存活能力。Aβ(下标 25~35)可以明显升高细胞培养上清液中MDA含量，降低GSH的含量；Res可使细胞培养上清液中MDA含量下降，GSH含量增加。

The changes of the structure of the spinotrapezius microvessel were observed by microscope under transillumination.

微泡空化介导外源大分子物质传输到组织间隙的外溢通道实质是血管内皮细胞的撕裂所致，撕裂发生在细胞核附近；这种外溢的通道可以是一过性产生，具有可修复性；红细胞可以通过小于自己直径的外溢通道。

Not only the inorganic-organic hybrid but also the porous structures make coordination polymers become one kind of unique functional materials toward wide applications of catalysis, chirality,conductivity,luminescence,magnetism,non-linear optics,porosity or zeolitic behavior,and molecular devices.

配位聚合物除了可兼具金属离子和配体的性质之外，离子与配体之间的相互作用和聚合物中的空腔也都赋予了它更多的特殊性能。

Jim said he would "jis''s soon have tobacker in his coffee;" and found so much fault with it, and with the work and bother of raising the mullen, and jews-harping the rats, and petting and flattering up the snakes and spiders and things, on top of all the other work he had to do on pens, and inscriptions, and journals, and things, which made it more trouble and worry and responsibility to be a prisoner than anything he ever undertook, that Tom most lost all patience with him; and said he was just loadened down with more gaudier chances than a prisoner ever had in the world to make a name for himself, and yet he didn't know enough to appreciate them, and they was just about wasted on him.

杰姆说他宁愿在他咖啡壶里放点儿烟叶子的。随后他牢骚一大串，说又要栽毛蕊花，又要给耗子奏口拨琴，又要对蛇、蜘蛛之类献殷勤。并且作为囚徒，论麻烦、论烦恼、论责任，难上加难的，而在这些活儿以外，还得磨笔、题词、写日记、如此等等，没有料想到做囚徒须得干这么多事。这么一说，汤姆可火了，对他失去了耐性。他说，杰姆空有这么好的机会，能比世上任何一个囚徒扬名天下，却不知好歹，眼看这些好机会正在他手里给白白错过了。

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。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
