使承受

Industrial civilization free man from the slash-and-burn cultivation, and the progress of productivity brought about material wealth and satisfied the continual increasing material requisite. In the meantime, people have to endure the threat and the destruction to their self-living environment.

工业文明使人类摆脱了刀耕火种的时代，生产力水平的进步给人类带来了极大的物质财富，满足了人类不断增长的物质需求，但同时人们又不得不承受由此带来的对自身生存环境的威胁和破坏。

On the premise of limiting the contributing rate of oldage insurance to a generally acceptable amount and maintaining a stable replacement rate or a moderate growth, we can ensure a sustainable development of oldage insurance system.

养老保险的可持续发展，就是在养老保险缴费率保持在人们可承受限度内的前提下，使替代率基本不变或适当提高。随着人口日益老龄化，现收现付制难以维持及持续发展。

5 How can we use matter and energy more sustainably?

我们如何使物质和能量更加能承受？

In order to help for evaluating properties of soil in interaction more precisely, the paper applies elastic theory solution on different modulus in tension and compression for vertical load into semi-infinite elastic body. Through quoting Heaviside function, the solution of elasticity theory with different modulus in tension and compression is established founded on the solution of elasticity theory for the material incapable in tension and Mindlinsolution for equal modulus.

为使地基土在共同作用中的行为特征评价更为合理，本文应用了半空间问题竖向荷载下地基土的拉压模量不同弹性理论解，该理论解是通过引入Heaviside函数，利用不能承受拉应力材料的弹性理论解并结合拉压模量相等的经典Mindlin解而获得。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
