The method can calculate the Young's modulus and Poisson's ratio of rock mass which include rock, structure surface and anchor rope.

这种方法可以算出含有节理的岩体的变形模量和泊松比，以及加有锚索后岩体的变形模量和泊松比。

Some injected oocytes were activated by Sr(superscript 2+) after various incubation periods and observed for formation of a second polar body and pseudo-polar body.

在注射后的不同培养时间，对重构卵子以Sr(上标 2+)激活，观测第二极体和类极体的形成，同时对重构胚进行染色体计数，并将发育良好的重构胚进行输卵管移植。

To determine the most effectie temperature, different heat shocks (32, 35 and 38 8C) were applied to newly fertilized eggs at 8–11 min post-fertilization to inhibit the extrusion of polar body 1 (PB1), and ended when the second polar body began to form in control groups.

在受精后8－11分钟，用不同的热激温度（32，35，38℃）抑制第一极体（PB1）的排放，待对照组开始出现第二极体时停止处理，以确定最佳热激温度。

Within this context, microseparation and in vitro culture of early zygotic embryos from polyembryony Citrus is very important because it makes possible the use of immature hybrid embryos and accelerates the sexual hybridization breeding in Citrus.

本研究初步建立了多胚性柑桔早期合子胚的显微分离、离体培养及合子苗的鉴定体系，成功显微分离了柑桔早期合子胚并通过离体培养再生植株，具体结果如下： 1、多胚性柑桔早期合子胚显微分离的最适时期为授粉后50—55d。

Polycarbosilane was used as the preceramic for matrix formation and 2D layered 0°/90° fabrics as the reinforcement to fabricate C/SiC composites. The effect of pyrolysis temperature and slurry concentration on the properties of the composites was systematically studied.

采用聚碳硅烷作为碳化硅先驱体，以二维0°/90°正交编织碳布叠层后作为增强体，采用真空压力浸渍的方法制备了C/SiC复合材料，研究了裂解温度和浆料浓度对复合材料性能的影响。

The enantioselective degradation and pharmacokinetics of ethofumesate enantiomers in rabbits were investigated by a single intravenous administration at doses of 30 mg kg~-1 of racemate.

以大白兔为试验动物，采用静脉注射外消旋体的给药方式，考察了给药后不同时间点的血药浓度以及脑组织、肝脏和胆汁中左右旋体的残留量。

Methods Proteins existed in adult Schistosoma japonicum membrane were extracted by Triton X-100 and purified through reverse-phase high performance liquid chromatography,and the main protein peaks were then collected separately. 125 I-LDL of human plasma as the ligand, through the radioautography and radioligand binding assay, the protein which can bind human serum 125 I-LDL specifically was identified.

自人工感染家兔的肠系膜下静脉取日本血吸虫成虫，用非离子去污剂TritonX 10 0抽提出日本血吸虫成虫表膜蛋白，反相高效液相色谱进行分离纯化后，收集各主要分离蛋白峰，以12 5I标记的人血浆低密度脂蛋白作为放射性配体，经放射性自显影及放射性受体配体结合分析鉴定能与人血浆12 5I LDL特异结合的蛋白。

Methods 65 teeth resinified with radiopaque resinifying agent in vitro were evaluated on X-ray films and through stereomicroscope.

对采用碘化钠显影塑化剂塑化后的65颗离体牙，进行X线片和体视镜下评定。

After about six months, in the process of stabilizing may seem skewed to some extent, but if there is still askew after that, the reason for this is that the process of prosthesis surgery positioning itself slightly skewed, or in after not yet completely fixed period by the impact of, this situation need to unplug and then re-insert the prosthesis, but if it has not completely fixed may be corrected.

术后的6个月左右内，在稳定下来的过程中可能会在一定程度上显得歪斜，但如果这之后仍有歪斜，其原因就是手术过程中假体的定位本身稍有偏斜，或在术后还没有完全固定下来期间受到了冲击，这种情形需要拔除假体后再重新插入，但如果它还没有彻底固定下来则可予以矫正。

Methods Split the recombinant E. coli for expression of rhOP-1 by ultrasomication in ice bath and extract the inclusion body. Dissolve the inclusion body with 8mol/L urea, purify by SP-Sepharose chromatography, refold by gradient dialysis.

将表达rhOP-1的大肠杆菌菌体在冰浴下超声裂解，分离提取包涵体，用8mol/L尿素溶解，纯化后进行梯度透析复性。

The basic concept of FOP can be summarized as to further optimize effective prescription according to the standard of curative effects and with the aid of modern science and technology and theories of traditional Chinese medicine.

其基本内涵可概括为：以确有疗效的中药复方为研究对象，以现代科学技术和传统中医药理论为技术支持，以该复方所治病证的药效响应为评价标准，以优化重组疗效更优的新复方为研究目的。

Ever since our world has been a world, native forests have been indiscriminately exploited by man.

自从我们的世界一直是世界原生森林被任意剥削人。
