Objective: To study the anti-tumor effect and the influence on the level of IL-2 and IL-4 by the decoction of branch of Juglans Maxim in mice bearing S180 tumor cells.

目的：探讨山核桃树枝水煎剂的抑瘤作用及其对S180荷瘤小鼠外周血白细胞介素-2(IL-2)和白细胞介素-4(IL-4)水平的影响。

Prophenoloxidase is a key enzyme for mediating melanotic encapsulation of oocysts,which may be transformed into active phenoloxidase by limiting proteolysis.

而前酚氧化酶(Prophenoloxidase，PPO)是介导卵囊黑化包被反应的一种关键酶，活化后可催化酪氨酸羟基化为二羟基苯基丙氨酸，二羟基苯基丙氨酸和多巴胺可进一步氧化为具有活性的苯醌活性，苯醌即可介导蛋白交联并聚合成黑色素层固定、隔离或杀死入侵的病原体。

A projectile with ground-air rocket by the burst of TNT has been designed for dispersing metaldehyde into the clouds on a large scale.

为了地面利用小火箭有效地对云大量撒播介乙醛，我们设计了一种用 TNT 分散介乙醛的药桂。

But hexagonal zinc metatitanate (ZnTiO_3) decomposes to orthotitanate (Zn_2TiO_4) with relatively bad microwave dielectric properties at ~945℃.

但是六方相ZnTiO_3会在945℃以上分解为微波介电性能极差的立方相Zn_2TiO_4，这将严重恶化陶瓷的微波介电性能。

SO42- bonded to free -OH on pore walls of metatitanic acid during the calcinations acts as the pore structure-directing agent and pore structure support.

不使用有机模板剂，采用超声化学法一步水解制得吸附硫酸根的介孔偏钛酸，500 ℃焙烧得到介孔SO42-/TiO2固体超强酸。

The number of hydrogen bond between methylol groups and other groups cut in dielectric relaxation increased with increasing WPG based on the activation enthalpy.

根据表观活化焓求得介电松弛过程中需要切断的氢键结合数量，构筑了二氧化硅/木材复合材料介电松弛回转取向运动模型，随着增重率的增加，需要切断的氢键数量增加。

Moreover, taking the adsorption process from oven-dry state to the equilibrium state in 20℃,60%RH environment as an example, the dielectric relaxation based on the reorientation of adsorbed water molecules was separated out from that based on the methylol groups in the amorphous region of wood cell wall.

以绝干状态→20℃，60%RH 平衡态的吸湿过程为例，将基于吸着水分子回转取向运动的介电弛豫与基于木材无定形区中伯醇羟基回转取向运动的介电弛豫进行分离，并在 Eyring 的绝对速度反应论的基础上，求得了与吸着水分子进行回转取向运动相关连的热力学量，得到了在吸着过程中吸着水分子与木材吸着点之间的氢键结合随着水分吸着进程的变化情况。

Insulation resistivity and kmax were not simply and monotonically changed with the content of silver.

结果表明：银迁移到陶瓷介质中导致介电性能的变化，具体表现为居里点的移动，介电峰值的下降，但并不是简单的单调上升或下降的关系。

In the C-terminal of the protein, there is a 40% homology to olfactomedin, which is a major component of the extracellular matrix of the olfactory neuroepithelium. The region includes all reported TIGR gene mutations, which indicates that it is associated with cellular binding activity.

在蛋白的 C-末端部分在一个区域与嗅觉介导素40%同源，嗅觉介导素是嗅神经上皮的细胞外基质的一种主要成分，这个区域含有所有已经报告的 TIGR 基因突变，提示其与细胞结合活性有关。

Thus our study indicates that impaired immunity against nontyphoidal Salmonella bacteremia in HIV infection results from excess inhibitory antibodies against Salmonella LPS whereas serum killing of Salmonella is induced by antibodies against outer membrane proteins.

他们的发现意味着HIV所造成的缺陷不止是细胞介导的免疫，而体液免疫（是由分泌的抗体所介导的）在以LPS蛋白为标靶的免疫反应中也受到了相当大的损害。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
