Common Reflection Surface stack is a brand-new and special ZO imaging method, the theory of CRS stack stems from paraxial ray theory, the biggest difference between CRS stack and conventional ZO imaging method is that it consider a reflector R as a circular reflector segment Cr placed in the vinicity of reflector R, Cr can be seen as the second order approximation of the reflector. The CRS traveltime surface is the multi-coverage reflection response of the reflector mirror assigned to R.

共反射面元（CommonReflection Surface=CRS）叠加技术是一种全新的、特殊的零偏移距剖面成像方法，CRS迭加理论源于傍轴射线理论，它与普通的零偏移距剖面成像方法的最大区别是它认为地下反射层是由许多个小反射弧段互相叠合组成的，认为来自某反射点附近的一个邻域内的反射信息都可以对该反射点的成像作出贡献，因此对该反射点进行零偏移距成像时就应该聚焦更多的能量参与迭加。

In this study the clubroot resistant CR DH line, susceptible inbred line 94SK of Chinese cabbage, the resistant and susceptible DNA bulks constructed from F2 individuals of CR DH line and 94SK were used to select the adaptive AFLP primer combination. AFLP analysis was performed with 256 Pst Ⅰ/Mse Ⅰ primer combinations.

此外，Cr相中的NiAl微粒粗化，在Cr相中出现了位错线。

The results showed that the PUR/CR blends with better thermal aging resistance could be obtained when mass ratio of PUR/CR was 20/80, amount of sulfur was 1.0 phr to 1.5 phr, carbon black N 220 was 40 phr, softening agent coumarone indene resin was 5 phr and antioxidant was antioxidant RD.

结果表明，当PUR与CR的质量比20/80、硫黄用量1.0~1.5份、炭黑选用N220且其用量40份、软化剂选用古马隆树脂且用量5份以及选用防老剂RD时，可以得到耐热老化性能较好的PUR/CR共混物。

Experimental results show that the algorithm can segmentalize ROI effectively, CR is higher than 30, PSNR of the whole image is higher than 42 dB, and the object keeps original fidelity. Inter-frame CR is about 7, background has cumulative error and PSNR is higher than 40 dB.

实验结果表明，该算法在帧内能有效地划分感兴趣区域，压缩率在30以上，峰值信噪比在42dB以上，目标无失真；帧间压缩的压缩率在7左右，背景区域有误差累积，但整体图像的峰值信噪比都在40dB以上，目标无失真。

In this study, Fe and sodium dithionite solutions were added into Cr-spiked soils and their effects on the decrease of availability of Cr were investigated.

本研究旨在探讨将Fe或连二亚硫酸钠（Na2S2O4）等化学还原剂施於Cr污染之碱性土壤，降低有效性六价铬含量的效果。

In the presence of PD , the dissolution rates of Cr and Ni in 304 matrix decreased obviously, and the molar percentages by which various components in 304 stainless steel dissolved were different from those in the absence of PD. AAS data indicated that regardless of the presence of PD the dissolution of Fe, Ni and Mn took the form of divalence, while Cr dissolved in the form of trivalence.

PD对304不锈钢在盐酸中的腐蚀存在"选择性抑制"效应，能显著减缓Cr和Ni的溶解，改变各元素溶解的比例，导致耐蚀组分在电极表面富集。

The meta-peridotite consists of dunite, harzburgite, lherzolite, feldspar-bearing lherzolite and garnet-bearing lherzolite and contains residual spinel with Cr#s [100*Cr/] of 30-57 and Mg#s [100*Mg/(Mg+Fe2+)] of 50-75, indicating an Al- and Mg-rich series.

变质橄榄岩主要为纯橄岩、方辉橄榄岩、二辉橄榄岩、含长二辉橄榄岩和含石榴石二辉橄榄岩，岩石中残余尖晶石的Cr'值=100×Cr/(Cr+Al为30～57，Mg'值=100×Mg/(Mg+Fe2+为50～75，指示一个富Al和Mg成分系列。
