The results showed that some holes on the nuclear membrane of the two kinds of the cells besides normal cell structures and there are some secretive pellets of protein with more high density of electronics around the nuclear of the cells, these pellets maybe is the regulatory matter of living things growth and around o'clock section rule, It is important to sturdy the ultrastructure of brain tissues and the physiological function of Tupaia belangeri chinensis .

利用电镜观察了树鼠句Tupaia belangeri chinensis的脑垂体和松果体细胞的超微结构，结果显示这两类细胞除了有正常细胞结构外，核膜孔较大且在核周围还有一些电子密度不同，大小不一的蛋白质分泌颗粒，这些颗粒可能是生物个体调节各种生理生化功能、生长发育和昼夜节律的信使物质，这对进一步研究树鼠句脑组织结构及其生理功能有一定意义

The situation of abnormal development of male cells is as follows:microspore mother cell can't enter into meiosis because of intense vacuolation,shrink and disintegration of its cytoplasm;although vacuolated microspore mother cell can enter into meiosis,it can't form normal dyad and degenerate in the middle process;dyad and tetrad become vacuolated and can't develop normally;cytoplasm of microspore shrinks around the nucleus at the stage of central nucleus microspore,the shape of microspore is twisted into crescent or irregular shape,at last its cytoplasm and nucleus are disintegrated and crescent vacant microspore presents;nutritive substances can't be accumulated at the stage of vacuolated microspore,cytoplasm is disintegrated,and microspore turns into a big vacant pollen.

雄性细胞异常发育有几种情况：小孢子母细胞强烈液泡化，细胞质收缩解体，不能进入减数分裂；小孢子母细胞液泡化，虽能进入减数分裂，但不能形成正常二分体而中途退化；二分体、四分体细胞液泡化，不能进行正常发育；单核小孢子中央期，细胞质收缩包围核，小孢子形状扭曲呈月牙形或不规则形，最终细胞质和核解体而呈月牙形的空壳小孢子；单核液泡期的小孢子不能积聚营养物质，细胞质解体而成为大的空壳花粉粒。

Maintaining the optimum level chloride ion concentration is beneficial to electrodeposits.

当Cl~-浓度在10～20mg·L~(-1)范围内，成核的晶核数密度达较大，即氯离子的最适宜添加量。

Then, David has brought the human Moon's liberator, 5000 are made urgently and turns to a new generation, the most advanced counter-attack class person robot soldier, had this super Assassin's mace, is preparing the investment super nuclear weapon jumbling together all to relax with the entire unification, after all uses the super nuclear weapon on the Moon, although may get quick results instantaneous may solve the problem, but can bring the long-time nucleus pollution to the Moon, because this time cannot be suitable completely on Earth's nucleus pollution government measure on the Moon, eliminates this is the intense detonation, once the computation fault, extremely has the possibility to explode the Moon to surrounds Earth's track, thusCreates the disastrous consequence, these reasons, all are restrict this time Earth humanity to invest the super nuclear weapon the basic reason, these use in coping with raids the planetoid fatal weapon certainly not common nuclear weapon, their detonation equivalent is extremely astonishing, to as a last resort cannot use.

就这样，大卫带来了人类月球的救星，五千名被紧急制造并升级换代，最为先进的反击类人机器人战士，有了这一超级杀手锏，正准备投入超级核武器的混为一谈与全统一全都松了一口气，毕竟在月球上使用超级核武器，虽然可以立竿见影瞬间就可以解决问题，但是会给月球带来长久的核污染，因为此时在地球上的核污染治理措施并不能在月球上完全适用，除此就是强烈的爆炸，一旦计算失误，就极有可能把月球炸离环绕地球的轨道，从而造成灾难性后果，这些原因，都是制约此时地球人类投入超级核武器的根本原因，这些用于对付来袭小行星致命武器绝非一般的核武器，它们的爆炸当量非常惊人，不到万不得已是绝不能使用的。

In testing the rifting force of hydro-cylinder, a new calculating met hod was presented, which can calculate the rifting force everyw...

在校核油缸提升力时，提出了一种新的计算方法，可计算出任一位置时的提升力，从而可找出最大提升力，使校核更准确。

Results:(1) The rats produced amphetamine CPP after treated with 2 mgkg^(-1) amphetamine for 4 days. Ketamine and low, middle, high dose rhynchophylline all could eliminate the CPP effect, and the effect of rhychophylline was increased in a dose-dependent manner. Rhychophylline itself could not induce CPP in normal rats.(2) When compared with normal rats, the NR2B expression in nucleus accubens and amygdaloid of the model rats was obviously increased. Ketamine and middle, high dose rhynchophylline could decrease NR2B expression induced by amphetamine, while low dose rhynchophylline did not affect NR2B expression. Rhynchophylline had no effect on RN2B expression in normal rats.

结果：(1)建立了苯丙胺（2mgkg^(-1)，连续4d）诱导的位置偏爱模型，氯胺酮及钩藤碱低、中、高剂量均可消除苯丙胺诱导的位置偏爱效应，随钩藤碱剂量增加其效应加强，且本身无精神依赖性；(2)苯丙胺模型组大鼠伏核和杏仁核NR2B蛋白表达增加，氯胺酮及钩藤碱中、高剂量抑制NR2B表达，低剂量及本身对NR2B表达无影响。

All experiment animals lived well with no death or malignant arrhythmia following cell transplantation. Frozen sections of the heart showed a few blue-stained cells under the fluoroscope in the cell transplantation group 4 weeks later. This indicated that stem cells were successfully homing. Using hematoxylin-eosin staining, homing cells were distributed over the infarct zone, with the presence of single or mass. In the model control group, no blue-stained cells were determined.

细胞移植后两组大鼠均存活良好，未出现死亡及恶性心律失常，4周后细胞移植组心脏冰冻切片荧光镜检显示心肌内有少量胞核蓝染的细胞，提示干细胞成功归巢，结合苏木精-伊红染色，归巢细胞位于心肌梗死灶周边区域，呈单个或小团聚集；而模型对照组心肌切片未见胞核蓝染的细胞。

Acterial artificial chromosome has several notable advantages, such as inserting large fragments, maintaining the stability of inserted DNA in E.coli, producing few chrisms, recovering inserted DNA from E.coli cell and easy in library construction.
