查询词典 strain

We selected Streptomyces strain FXJ2.014 with high bioactivity for further analysis and found additional metabolites in fermentation extracts of cocultures of strains FXJ2.014, FXJ1.296 and AS 4.1252 respectively with B. subtilis. Quinomycin A was the main bioactive metabolite produced by the monoculture of strain FXJ2.014, while a new quinomycin-like component named FXJ2.014-HB was produced when strain FXJ2.014 was cocultured with B.

发现FXJ2.014、FXJ1.296、AS 4.1252三株菌与枯草芽孢杆菌共培养时产生其在相同条件下单培养时没有的物质，其中链霉菌FXJ2.014单培养时主要产生醌霉素A，共培养时产物中增加了醌霉素结构类似物FXJ2.014-HB。

Mechanical strains also regulated the protein and mRNA expression of several differentiation markers, as well as the activation of extracellular signal-regulated kinases, p38 MAP kinase and protein kinase B in a frequency-dependent manner. Furthermore, the inhibition of p38 pathway could block the strain-frequency induced the phenotype modulation of VSMCs, neither ERKs nor Akt. Frequency of mechanical strain, not conditioned medium, regulated the phenotype of VSMCs in a frequency-dependent manner. Rho-GDI alpha was suppressed by the mechanical strain at 1Hz.

Gallo laboratory strain of AIDS was reported米库拉斯波Bo Weike separated, the source of its Boboweike has been vague, then simply said to be from a number of patients with mixed blood, This separation is very normal. In May 1986, Gallo laboratory in the "Science" made a correction of their May 4, 1984 posted on the "Science" on the paper, the French had mistakenly provided by the LAV strain of the photos as HTLV-3 The strain of photos.

盖洛实验室的艾滋病毒株据称是米库拉斯·波波维克分离出来的，对其来源波波维克一直含糊其词，后来干脆说是从许多患者的混合血液中分离的，这种分离方法是很不正常的。1986年5月，盖洛实验室在《科学》发了个更正，他们1984年5月4日登在《科学》上的论文中，误把法国人提供的LAV株的照片当成了HTLV-3株的照片。

The axial stress-strain curves under various level of confinement and strain rate were derived according to the experiment. It shows that the strength and ductility increase significantly because of confinement, and finally turn into plasticity, also it is strain rate sensitive.

实验得到了水泥砂浆在不同围压、不同应变率下的轴向应力应变曲线，发现材料在围压作用下抗压强度和韧性大大提高并且整体进入了伪塑性，而材料的应变率效应也是显著的。

The strain did not infect rice, soybean, sunflower and mung bean,then wheat, maize and yellow corn were susceptible to the strain. The strain has the characteristic of host selective-specificity.

水稻，大豆，向日葵和绿豆对菌株不敏感，而小麦，玉米和谷子等作物对菌株较敏感，表明菌株寄主相对专一。

When NiTi alloy was tensiled at 600 ℃ and at a lower strain rate, the dynamic recrystallization occurred. Without electric field the stress-strain curves were characterized by periodical undee graph, while under the electric field they presented steady state. When deformation under the electric field, both strain hardening and recrystallization take place simultaneously, thus the flow stress curves exhibits steady state.

NiTi合金高温拉伸变形过程中会发生动态再结晶，在应变速率较低时其应力-应变曲线呈周期性波浪形，在应变速率较高时其应力-应变曲线则呈现较平滑稳定的态势；施加电场作用时抑制了这种周期波浪形变化，使应力-应变曲线呈平滑稳态变化。

By the pot experiment in nitrogen-free sand, the difference of the parental strain and marked strains with cfp gene on three cultivars was tested. One marked strain which was not significantly different with the parental strain for the competition stady with soil indigenous strains under field conditions .

通过无菌砂培试验，进行了标记菌株与出发菌株在三个品种上的差异性检测，选出一株在瘤数、植株干重、叶绿素含、全氮含量等各方面指标与出发菌株最为接近的标记菌株用于控制条件下的田间小区试验，比较标记菌株与土著菌株在三个品种上的竞争结瘤能力，结果表明

The deforma-tion history and strain characteristic during deformation of material are describedby the flow line in which the deformation history and strain characteristic re-strain the crack initiation at stage II and the crack propagation at stage III.

材料的流变曲线描述了形变过程中的变形历史和应变特性，有明显的阶段性，其中第Ⅱ阶段的变形历史和应变特性制约着裂纹的启裂过程，第Ⅲ阶段的变形历史和应变特性制约着裂纹的扩展过程。

A red strain with an inferior dorsal bred to a red strain with a superior dorsal has a much better chance after the spin of the gene roulette wheel than a cross to another color strain.

但是同种的鱼线必须要多，如此才可补齐原有品系鱼种的原有基因（因为由於LINE BREEDING OR INBREEDING 后通常都会遗失掉一些对偶基因因而导致所谓基因弱化的发生）。

The developments of four strain components and the volumetric strain with number of cycles, the relationship between shear stress and shear strain and the effects of deviatoric stress and effective mean normal stress were studied.
