The step response and impulse response of homogeneous earth half space, marine double half space and four-layer earth models to horizontal electric dipole source were computed in this paper. A concept of transient impulse time was put forward.

本文计算了水平电偶极子源均匀大地半空间，海洋均匀双半空间和海洋四层模型的阶跃响应和冲激响应，提出了瞬变冲激时刻的概念。

Methods Rats′ stress ulcer model was made by cold water soaking and was properly treated with drugs such as hyoscine, dexamethasone, ranitidine and losec. The amount and pH of gastric juice, change of gastric mucosa and PGs and ACTH of blood were determined. Results After rats were fasted for 24 hours a little gastric juice was aspirated.

通过冷束缚法制成大鼠应激性溃疡模型，以东莨菪碱、地塞米松、雷尼替丁、洛赛克等药物进行应激性溃疡的防治，检测胃液量、pH值及胃粘膜的变化，测定PGs和ACTH的水平。

Results:By short term stimulating,the vitality of blood serum enzyme increased and the change of ultrastruucture showed the hypermetabolism of cardiac muscles;with the state of high stress prologing,the vitality of blood serum enzyme decreased gradually;the damage ...

结果：随应激状态时间延长、强度增加，血清心肌酶（LD H、HBD H、C K、GO T）活力短时间刺激升高，然后逐渐下降，心肌超微结构短期刺激为代谢亢进的变化，以后呈逐渐加重的损伤性改变。结论：高应激状态能够引起大鼠心肌损伤。

It is proved by the analytical and numerical method that the modulus of the Z transform of a finite impulse response sequence has no extreme values at poles (with maximums along imaginary axis and no extreme values along real axis), and the negative second order derivative of the modulus normalized along frequency axis with respect to angular frequency has maximums at the poles.

根据实测瞬态电磁脉冲响应，较好地反演了导体球和导体长椭球的冲激响应，测得了它们的雷达截面和谐振频率。用解析与数值相结合的方法证明了有限冲激响应序列Z变换的模在极点无极值（沿虚轴有极大值，沿实轴无极值），而沿频率轴的归一化值对角频率的负二阶导数在极点有极大值。

Endorphinsin the sydtem of nerve,internal secretion and immunity.

综上所述，不同应激源对机体产生不同的影响，针灸作为一种良性应激源，对机体免疫功能具有明显的正向调节作用。

To judge two groups people in the day that people join in and 3 months later by brief psychiatric rating scale and nurse observe scale.results: comparing point value at the time of joining , 3 months later, the total score of nosie ,social ability, social interest and personal hygiene are apparently higher, irritableness, psychosis performance, retraction, depression and bprs are much lower.

结果：3个月后研究组患者的nosie量表的社会能力、社会兴趣、个人卫生3因子分明显高于入组时的分值，而激惹、精神病表现、退缩、抑郁4因子分和bprs分明显低于入组时的分值；与对照组比较：研究组患者在精神病表现、社会能力，社会兴趣、个人卫生、激惹、迟滞、抑郁等评分有显著性差异。

Based on the previous research,one gene of Bombyx mori named as HSP20.8 can be over expressed in kidney-shaped eggs than in other organs.

前期研究发现，相对于其它组织器官，有一种低分子量热激蛋白在家蚕肾型卵中高量表达，并命名为低分子量热激蛋白HSP20.8。

In the present study we found that capsaicin enhanced LTP but reduced LTD as reflected by a leftward shift of the threshold for synaptic plasticity.

我们发现的辣椒素对LTP/LTD的影响与行为学应激对LTP/LTD的影响，两者效应恰恰相反，应激是易化LTD的诱导而损伤LTP的诱导。

The effects of Cortex phellodendri alkaloid on splenic lymphocyte proliferation after heat stress were detected by MTT chromatometry.On the basis of the above detection,CPAs extracted by limewater,ethanol,sulfuric acid water and the mixture of sulfuric acid-and-ethanol were choosen.

采用MTT法测定了热应激后小鼠脾淋巴细胞增殖的情况，以此作为醇提、碱提、酸醇提、酸提4种提取方法所得黄柏生物碱的筛选依据；采用ELISA法测定了醇提黄柏生物碱对热应激后小鼠脾淋巴细胞IFN-γ、IL-4分泌水平的动态影响。

It is shown that maximum temperature value of the field's will rise while the Mach number increases. After the Mach number exceeds one, a clear bowshock is obtained in the simulation result, and the Mach angle decreases along with the Mach number. Those are consistent with theoretical results. While the Mach number is 3.5, even the radome inside is adiabatic, the maximum temperature is below 1000K. So the CVD diamond thick film radome can meet practical requirement of flight at 3.5 Mach number.

研究发现，随着马赫数的增加，温度场中最大温度值也随之增大；在马赫数大于1时，会产生明显的弓形激波，且激波的锥角随马赫数增加而减小，这与理论结果相一致；当马赫数为3.5时，即使在头罩内壁绝热条件下，温度场中最高温度值也在1000K以下，表明CVD金刚石厚膜可以满足Ma=3.5的实际飞行要求。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
